ITEM 1. BUSINESS

GENERAL

Pentair plc is a focused diversified industrial manufacturing company comprising three reporting segments: Water Quality Systems, Flow & Filtration Solutions and Technical Solutions. Water Quality Systems designs, manufactures, markets and services innovative water system products and solutions to meet filtration and fluid management challenges in food and beverage, water, swimming pools and aquaculture applications. Flow & Filtration Solutions designs, manufactures, markets and services solutions for the toughest filtration, separation, flow and fluid management challenges in agriculture, food and beverage processing, water supply and disposal and a variety of industrial applications. Technical Solutions designs, manufactures, markets and services products that guard and protect some of the world's most sensitive electrical and electronic equipment, as well as heat management solutions designed to provide thermal protection to temperature sensitive fluid applications and engineered electrical and fastening products for electrical, mechanical and civil applications.

Pentair strategy

Our strategy is to drive sustainable, profitable growth and return on invested capital improvements through:


•	building operational excellence through the Pentair Integrated Management System ("PIMS") consisting of lean enterprise, growth and talent management;


•	driving long-term growth in sales, operating income and cash flows, through growth and productivity initiatives along with acquisitions;


•	developing new products and enhancing existing products;


•	penetrating attractive growth markets, particularly outside of the United States;


•	expanding multi-channel distribution; and


•	proactively managing our business portfolio for optimal value creation, including consideration of new business platforms.

Unless the context otherwise indicates, references herein to "Pentair," the "Company," and such words as "we," "us," and "our" include Pentair plc and its consolidated subsidiaries. We are an Irish public limited company that was formed in 2014. We are the successor to Pentair Ltd., a Swiss corporation formed in 2012, and Pentair, Inc., a Minnesota corporation formed in 1966 and our wholly-owned subsidiary, under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

HISTORY AND DEVELOPMENT

In December 2013, the Company's Board of Directors approved changing the Company's jurisdiction of organization from Switzerland to Ireland. At an extraordinary meeting of shareholders on May 20, 2014, Pentair Ltd. shareholders voted in favor of a reorganization proposal pursuant to which Pentair Ltd. would merge into Pentair plc and all Pentair Ltd. common shares would be cancelled and all holders of such shares would receive ordinary shares of Pentair plc on a one-to-one basis. The reorganization transaction was completed on June 3, 2014, at which time Pentair plc replaced Pentair Ltd. as the ultimate parent company (the "Redomicile"). Shares of Pentair plc began trading on the New York Stock Exchange ("NYSE") on June 3, 2014 under the symbol "PNR," the same symbol under which Pentair Ltd. shares were previously traded.

Although our jurisdiction of organization is Ireland, we manage our affairs so that we are centrally managed and controlled in the United Kingdom (the "U.K.") and therefore have our tax residency in the U.K.

Our former parent company, Pentair Ltd., took its form on September 28, 2012 as a result of a reverse acquisition (the "Merger") involving Pentair, Inc. and an indirect, wholly-owned subsidiary of Flow Control (defined below), with Pentair, Inc. surviving as an indirect, wholly-owned subsidiary of ours. "Flow Control" refers to Pentair Ltd. prior to the Merger. Prior to the Merger, Tyco International Ltd. ("Tyco") engaged in an internal restructuring whereby it transferred to Flow Control certain assets related to the flow control business of Tyco, and Flow Control assumed from Tyco certain liabilities related to the flow control business of Tyco. On September 28, 2012 prior to the Merger, Tyco effected a spin-off of Flow Control through the pro-rata distribution of 100% of the outstanding ordinary shares of Flow Control to Tyco's shareholders (the "Distribution"), resulting in the distribution of approximately 110.9 million of our ordinary shares to Tyco's shareholders. The Merger was accounted for as a reverse acquisition under the purchase method of accounting with Pentair, Inc. treated as the acquirer.

On September 18, 2015, we acquired, as part of Technical Solutions, all of the outstanding shares of capital stock of ERICO Global Company ("ERICO") for approximately $1.8 billion (the "ERICO Acquisition"). ERICO is a leading global manufacturer and marketer of engineered electrical and fastening products for electrical, mechanical and civil applications. ERICO has employees in 30 countries across the world with recognized brands including CADDY fixing, fastening and support products; ERICO electrical grounding, bonding and connectivity products and LENTON engineered systems.

On August 18, 2016, we entered into a share purchase agreement to sell our Valves & Controls business to Emerson Electric Co. for a purchase price of $3.15 billion in cash, subject to customary adjustments. We believe the sale will be completed by the end of the first quarter of 2017, subject to customary regulatory approvals and closing conditions. The results of the Valves and Controls business have been presented as discontinued operations and the related assets and liabilities have been reclassified as held for sale for all periods presented. The Valves & Controls business was previously disclosed as a stand-alone reporting segment.

Our registered principal office is located at 43 London Wall, London, EC2M 5TF, United Kingdom. Our management office in the United States ("U.S.") is located at 5500 Wayzata Boulevard, Suite 600, Minneapolis, Minnesota.

BUSINESS AND PRODUCTS

Reporting segment and geographical financial information is contained in ITEM 8, Note 16 of the Notes to Consolidated Financial Statements, included in this Form 10-K. The following is a brief description of each of the Company's reportable segments and business activities.

WATER QUALITY SYSTEMS

The Water Quality Systems segment designs, manufactures, markets and services innovative water system products and solutions to meet filtration and fluid management challenges in food and beverage, water, swimming pools and aquaculture applications.

Water Quality Systems offers a comprehensive product suite that includes a full range of recreational water treatment equipment including energy-efficient pumps, point-of-entry / point-of-use filtration for residential and commercial applications including foodservice, valves, UV sanitization and automation controls. We offer design and consulting services and our advanced water technologies are used across a wide number of industries including industrial, residential, commercial, municipal, foodservice, aquaculture, aquaponics, aquatic life support systems, irrigation and flood control, wastewater and more. Our equipment and solutions are found in swimming pools and spas, aquaculture farms, laboratories, water purification and sanitation systems, foodservice operations, and in other applications across the globe.

Brand names for Water Quality Systems include Pentair, Pentair Aquatic Eco-Systems, Everpure, Kreepy Krauly, Sta-Rite and Shurflo.

Customers

Water Quality Systems customers include businesses engaged in wholesale and retail distribution in the residential & commercial, food & beverage and infrastructure verticals. Customers in the residential & commercial vertical also include end-users and consumers.

Seasonality

We experience seasonal demand with several end customers and end-users within Water Quality Systems. End-user demand for pool equipment follows warm weather trends and is at seasonal highs from April to August. The magnitude of the sales increase is partially mitigated by employing some advance sale "early buy" programs (generally including extended payment terms and/or additional discounts).

Competition

Water Quality Systems faces numerous domestic and international competitors, some of which have substantially greater resources directed to the verticals in which we compete. Competition focuses on brand names, product performance (including energy-efficient offerings), quality and price. We compete by offering a wide variety of innovative and high-quality products, which are competitively priced. We believe our distribution channels and reputation for quality also provide us a competitive advantage.

FLOW & FILTRATION SOLUTIONS

The Flow & Filtration Solutions segment designs, manufactures, markets and services solutions for the toughest filtration, separation, flow and fluid management challenges in agriculture, food and beverage processing, water supply and disposal and a variety of industrial applications.

Flow & Filtration Solutions is involved in the entire water, water treatment and wastewater system from advanced filtration, desalination, water supply to water disposal, process and control. Our solutions also help in critical municipal challenges around flood control, storm water management, de-watering, dredging and fish friendly solutions. From engineered solutions to installation and maintenance, we support a broad range of solutions and services specifically tailored to address our customers' needs for water reuse, water availability and water stewardship. Solutions include light duty diaphragm pumps and pressure boosters, high-flow turbine pumps and solid handling pumps, as well as advanced filtration, oil & gas separation, membrane technology, energy recovery and quality control and instrumentation.

Applications for Flow and Filtration Solutions' products include precision agriculture, biogas upgrading, water supply and disposal, fire applications and food and beverage processing. Brand names for Flow & Filtration Solutions products include Aurora, Berkeley, Codeline, Fairbanks-Nijhuis, Haffmans, Hypro, Sta-Rite, Südmo and X-Flow.

Flow & Filtration Solutions customers include businesses engaged in wholesale distribution and retail across the residential, commercial, food and beverage, infrastructure, industrial, and energy verticals. Customers also include end-users as well as engineering procurement contractors, and original equipment manufacturers.

Seasonality

We experience demand for residential water supply products, infrastructure and agricultural products following warm weather trends, which are at seasonal highs from April to August. The magnitude of the sales increase is partially mitigated by employing some advance sale "early buy" programs (generally including extended payment terms and/or additional discounts). Seasonal effects may vary from year to year and are impacted by weather patterns, particularly by temperatures, heavy flooding and droughts.

Competition

Flow & Filtration Solutions faces numerous domestic and international competitors, some of which have substantially greater resources directed to the verticals in which we compete. Competition in Flow & Filtration Solutions focuses on brand names, product performance (including energy-efficient offerings and required specifications), quality, service and price. We compete by offering a wide variety of innovative and high-quality products, which are competitively priced.

TECHNICAL SOLUTIONS

The Technical Solutions segment designs, manufactures, markets and services products that guard and protect some of the world's most sensitive electrical and electronic equipment, as well as heat management solutions designed to provide thermal protection to temperature sensitive fluid applications and engineered electrical and fastening products for electrical, mechanical and civil applications.

Technical Solutions products include mild steel, stainless steel, aluminum and non-metallic enclosures, cabinets, cases, subracks, backplanes, engineered fastening solutions across a wide range of industries and verticals and thermal management systems including heat tracing, floor heating, fire-rated and specialty wiring, sensing, and snow melting and de-icing solutions for industrial, commercial and residential use.

The portfolio of products serves a range of industries, including use in the commercial, communications, energy, electronics, industrial, infrastructure, medical, and security & defense verticals. Brand names for Technical Solutions offerings include CADDY, ERICO, Hoffman, LENTON, Raychem, Schroff and Tracer.

Customers

Technical Solutions customers include electrical distributors, data center contractors, original equipment manufacturers, contractors mainly of greenfield developments and maintenance contractors. Technical Solutions has a global installed base of customers.

Seasonality

Technical Solutions generally experiences increased demand for thermal protection products and services during the fall and winter months in the Northern Hemisphere and increased demand for electrical fastening products during the spring and summer months in the Northern Hemisphere.

Competition

Within Technical Solutions, the equipment protection business faces significant competition in the verticals it serves, particularly within the communications industry, where product design, prototyping, global supply, price competition and customer service are significant factors. The industries and verticals served by the thermal management business are highly fragmented, comprising local markets and niches. The industries and verticals served by the engineered fastening solutions

business is relatively fragmented, with about a dozen major competitors and a large number of smaller suppliers. We compete by offering a wide variety of innovative and compatible products, which are competitively priced.

NEW SEGMENTATION

During the first quarter of 2017, we reorganized our business segments to reflect a new operating structure, resulting in a change to our reporting segments in 2017. As part of this reorganization, the legacy Water Quality Systems business segment was combined with the legacy Flow & Filtration Solutions business segment to form the Water reporting segment and now operates as a stand-alone business segment. In addition, the legacy Technical Solutions business segment will be renamed the Electrical reporting segment. All segment information presented throughout this Annual Report on Form 10-K, with exception of the table below, was prepared based on the reporting segments in place during 2016.

The below table presents sales and segment income under the revised reporting segments (Water and Electrical) for the years ended December 31, 2016, 2015, and 2014.

Total	$	642.1	$	750.0	$	(107.9	)	(14.4	)%

A substantial portion of our revenues result from orders received and product delivered in the same month. Our backlog typically has a short manufacturing cycle and products generally ship within 90 days of the date on which a customer places an order. However, a portion of our backlog, particularly from orders for major capital projects, can take more than one year depending on the size and type of order. We record as part of our backlog all orders from external customers, which represent firm commitments, and are supported by a purchase order or other legitimate contract. We expect the majority of our backlog at December 31, 2016 will be shipped in 2017.

Research and development

We conduct research and development activities primarily in our own facilities. These efforts consist primarily of the development of new products, product applications and manufacturing processes. Research and development expenditures during 2016, 2015 and 2014 were $114.1 million, $98.7 million and $96.4 million, respectively.

Environmental

Environmental matters are discussed in ITEM 3, ITEM 7 and ITEM 8, Note 17 of the Notes to Consolidated Financial Statements, included in this Form 10-K.

Raw materials

The principal materials we use in manufacturing our products are electric motors, mild steel, stainless steel, electronic components, plastics (resins, fiberglass, epoxies), copper and paint (powder and liquid). In addition to the purchase of raw materials, we purchase some finished goods for distribution through our sales channels.

We purchase the materials we use in various manufacturing processes on the open market and the majority is available through multiple sources which are in adequate supply. We have not experienced any significant work stoppages to date due to shortages of materials. We have certain long-term commitments, principally price commitments, for the purchase of various component parts and raw materials and believe that it is unlikely that any of these agreements would be terminated prematurely. Alternate sources of supply at competitive prices are available for most materials for which long-term commitments exist and we believe that the termination of any of these commitments would not have a material adverse effect on our financial position, results of operations or cash flows.

Certain commodities, such as metals and resin, are subject to market and duty-driven price fluctuations. We manage these fluctuations through several mechanisms, including long-term agreements with price adjustment clauses for significant commodity market movements in certain circumstances. Prices for raw materials, such as metals and resins, may trend higher in the future.

Intellectual property

Patents, non-compete agreements, proprietary technologies, customer relationships, trademarks, trade names and brand names are important to our business. However, we do not regard our business as being materially dependent upon any single patent, non-compete agreement, proprietary technology, customer relationship, trademark, trade name or brand name.

Patents, patent applications and license agreements will expire or terminate over time by operation of law, in accordance with their terms or otherwise. We do not expect the termination of patents, patent applications or license agreements to have a material adverse effect on our financial position, results of operations or cash flows.

Employees

As of December 31, 2016, we employed 26,000 people worldwide, of which 9,500 were in the U.S. and 9,000 were covered by collective bargaining agreements or works councils. Of the 26,000 people employed worldwide as of December 31, 2016, 7,500 relate to our Valves & Controls business classified as held for sale, of which 1,500 were in the U.S. and 2,200 were covered by collective bargaining agreements or works councils. We believe that our relations with the labor unions have generally been good.

Captive insurance subsidiary

We insure certain general and product liability, property, workers' compensation and automobile liability risks through our regulated wholly-owned captive insurance subsidiary, Penwald Insurance Company ("Penwald"). Reserves for policy claims are established based on actuarial projections of ultimate losses. Accruals with respect to liabilities insured by third parties, such as liabilities arising from acquired businesses, pre-Penwald liabilities and those of certain non-U.S. operations are established.

Matters pertaining to Penwald are discussed in ITEM 3 and ITEM 8, Note 1 of the Notes to Consolidated Financial Statements – Insurance subsidiary, included in this Form 10-K.

Available information

We make available free of charge (other than an investor's own Internet access charges) through our Internet website (http://www.pentair.com) our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and if applicable, amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act as soon as reasonably practicable after we electronically file such material with, or furnish it to, the U.S. Securities and Exchange Commission ("SEC"). Reports of beneficial ownership filed by our directors and executive officers pursuant to Section 16(a) of the Exchange Act are also available on our website. We are not including the information contained on our website as part of or incorporating it by reference into, this Annual Report on Form 10-K.

ITEM 1A. RISK FACTORS

You should carefully consider all of the information in this document and the following risk factors before making an investment decision regarding our securities. Any of the following risks could materially and adversely affect our business, financial condition, results of operations, cash flows and the actual outcome of matters as to which forward-looking statements are made in this document.

Risks Relating to Our Business

General global economic and business conditions affect demand for our products.

We compete in various geographic regions and product markets around the world. Among these, the most significant are global industrial markets and residential markets. We have experienced, and expect to continue to experience, fluctuations in revenues and operating results due to economic and business cycles. Important factors for our businesses and the businesses of our customers include the overall strength of the economy and our customers' confidence in the economy, industrial and governmental capital spending, the strength of the residential and commercial real estate markets, unemployment rates, availability of consumer and commercial financing, interest rates, and energy and commodity prices. The businesses of many of our industrial customers, particularly oil and gas companies, chemical and petrochemical companies, mining and general industrial companies, are to varying degrees cyclical and have experienced periodic downturns. While we attempt to minimize our exposure to economic or market fluctuations by serving a balanced mix of end markets and geographic regions, any of the above factors, individually or in the aggregate, or a significant or sustained downturn in a specific end market or geographic region could reduce demand for our products and services.

We compete in attractive markets with a high level of competition, which may result in pressure on our profit margins and limit our ability to maintain or increase the market share of our products.

The markets for our products and services are geographically diverse and highly competitive. We compete against large and well-established national and global companies, as well as regional and local companies and lower cost manufacturers. We compete based on technical expertise, reputation for quality and reliability, timeliness of delivery, previous installation history, contractual terms and price. Some of our competitors, in particular smaller companies, attempt to compete based primarily on price, localized expertise and local relationships, especially with respect to products and applications that do not require a great deal of engineering or technical expertise. In addition, during economic downturns average selling prices tend to decrease as market participants compete more aggressively on price. If we are unable to continue to differentiate our products, services and solutions, or if we are forced to cut prices or to incur additional costs to remain competitive, our business, financial condition, results of operations and cash flows could be materially and adversely affected.

Volatility in currency exchange rates may adversely affect our financial condition, results of operations and cash flows.

Sales outside of the U.S. for the year ended December 31, 2016 accounted for 41 percent of our net sales. Our financial statements reflect translation of items denominated in non-U.S. currencies to U.S. dollars. Therefore, if the U.S. dollar strengthens in relation to the principle non-U.S. currencies from which we derive revenue as compared to a prior period, our U.S. dollar reported revenue and income will effectively be decreased to the extent of the change in currency valuations, and vice-versa. During 2016, foreign currency translations had a 0.8 percent negative impact on our net sales. Fluctuations in foreign currency exchange rates, most notably the strengthening of the U.S. dollar against the Euro, could continue to adversely affect our reported revenue in future periods. In addition, currency variations can adversely affect margins on sales of our products in countries outside of the U.S. and margins on sales of products that include components obtained from suppliers located outside of the U.S.

Our future growth is dependent upon our ability to continue to adapt our products, services and organization to meet the demands of local markets in both developed and emerging economies and by developing or acquiring new technologies that achieve market acceptance with acceptable margins.

We operate in global markets that are characterized by customer demand that is often global in scope but localized in delivery. We compete with thousands of smaller regional and local companies that may be positioned to offer products produced at lower cost than ours, or to capitalize on highly localized relationships and knowledge that are difficult for us to replicate. Also, in several emerging markets potential customers prefer local suppliers, in some cases because of existing relationships and in other cases because of local legal restrictions or incentives that favor local businesses. Accordingly, our future success depends upon a number of factors, including our ability to adapt our products, services, organization, workforce and sales strategies to fit localities throughout the world, particularly in high growth emerging markets; identify emerging technological and other trends in our target end-markets; and develop or acquire competitive products and services and bring them to market quickly and cost-effectively. We have chosen to focus our growth initiatives in specific end markets and geographies, but we cannot provide assurance that these growth initiatives will be sufficient to offset revenue declines in other markets. The failure to effectively adapt our products or services could materially and adversely affect our business, financial condition, results of operations and cash flows.

Our business strategy includes acquiring businesses and making investments that complement our existing businesses. We may not be able to identify, finance and complete suitable acquisitions and investments, and any completed acquisitions and investments could be unsuccessful or consume significant resources, which could adversely affect our operating results.

We continue to analyze and evaluate the acquisition of strategic businesses or product lines with the potential to strengthen our industry position or enhance our existing set of product and service offerings. We cannot provide any assurance that we will be able to identify suitable acquisition candidates, obtain financing or have sufficient cash necessary for acquisitions or successfully complete acquisitions in the future or that completed acquisitions will be successful. Acquisitions and investments may involve significant cash expenditures, debt incurrences, equity issuances, operating losses and expenses that could have a material adverse effect on our business, financial condition, results of operations and cash flows. Acquisitions involve numerous other risks, including:


•	diversion of management time and attention from daily operations;


•	difficulties integrating acquired businesses, technologies and personnel into our business;


•	difficulties in obtaining and verifying the financial statements and other business information of acquired businesses;


•	inability to obtain required regulatory approvals;


•	potential loss of key employees, key contractual relationships or key customers of acquired companies or of ours;


•	assumption of the liabilities and exposure to unforeseen liabilities of acquired companies, including risks related to the U.S. Foreign Corrupt Practices Act (the "FCPA"); and


•	dilution of interests of holders of our shares through the issuance of equity securities or equity-linked securities.

It may be difficult for us to complete transactions quickly and to integrate acquired operations efficiently into our business operations. Any acquisitions or investments may ultimately harm our business, financial condition, results of operations and cash flows, as such acquisitions may not be successful and may ultimately result in impairment charges.

We may not complete the sale of our Valves & controls business in the time frame or on the terms we anticipate.

On August 18, 2016, we entered into an agreement to sell our Valves & Controls business to Emerson Electric Co. for a purchase price of $3.15 billion in cash, subject to certain customary adjustments. We believe the sale will be completed by the end of the first quarter of 2017, subject to customary regulatory approvals and closing conditions. The completion of the sale is subject to a number of risks and uncertainties, including the satisfaction of the conditions to the completion of the sale, the parties to the transactions obtaining the necessary regulatory approvals, the occurrence of any event, change or other circumstance that could give rise to the termination of the sale agreement and our ability to obtain the expected proceeds from the sale. These and other factors could impair our ability to complete the sale in the time frame and on the terms we anticipate, and this could have a material adverse effect on our financial position, results of operations or cash flows.

We may not achieve some or all of the expected benefits of our business initiatives.

During 2016, 2015 and 2014, we initiated and continued execution of certain business initiatives aimed at reducing our fixed cost structure and realigning our business. As a result, we have incurred substantial expense, including restructuring charges. We may not be able to achieve the operating efficiencies to reduce costs or realize benefits that were initially anticipated in connection with these initiatives. If we are unable to execute these initiatives as planned, we may not realize all or any of the anticipated benefits, which could adversely affect our business and results of operations.

We are exposed to political, regulatory, economic and other risks that arise from operating a multinational business.

Sales outside of the U.S. for the year ended December 31, 2016 accounted for 41 percent of our net sales. Further, most of our businesses obtain some products, components and raw materials from non-U.S. suppliers. Accordingly, our business is subject to the political, regulatory, economic and other risks that are inherent in operating in numerous countries. These risks include:


•	changes in general economic and political conditions in countries where we operate, particularly in emerging markets;


•	relatively more severe economic conditions in some international markets than in the United States;


•	the difficulty of enforcing agreements and collecting receivables through foreign legal systems;


•	the difficulty of communicating and monitoring standards and directives across our global network of after-market service centers and manufacturing facilities;


•	trade protection measures and import or export licensing requirements and restrictions;


•	the possibility of terrorist action affecting us or our operations;


•	the threat of nationalization and expropriation;


•	the imposition of tariffs, exchange controls or other trade restrictions;


•	difficulty in staffing and managing widespread operations in non-U.S. labor markets;


•	changes in tax treaties, laws or rulings that could have an adverse impact on our effective tax rate;


•	limitations on repatriation of earnings;


•	the difficulty of protecting intellectual property in non-U.S. countries; and


•	changes in and required compliance with a variety of non-U.S. laws and regulations.

Our success depends in part on our ability to anticipate and effectively manage these and other risks. We cannot assure you that these and other factors will not have a material adverse effect on our international operations or on our business as a whole.

Material cost and other inflation have adversely affected and could continue to affect our results of operations.

In the past, we have experienced material cost and other inflation in a number of our businesses. We strive for productivity improvements and implement increases in selling prices to help mitigate cost increases in raw materials (especially metals and resins), energy and other costs such as pension, health care and insurance. We continue to implement operational initiatives in order to mitigate the impacts of this inflation and continuously reduce our costs. We cannot provide assurance, however, that these actions will be successful in managing our costs or increasing our productivity. Continued cost inflation or failure of our initiatives to generate cost savings or improve productivity would likely negatively impact our results of operations.

Intellectual property challenges may hinder our ability to develop, engineer and market our products.

Patents, non-compete agreements, proprietary technologies, customer relationships, trademarks, trade names and brand names are important to our business. Intellectual property protection, however, may not preclude competitors from developing products similar to ours or from challenging our names or products. Our pending patent applications, and our pending copyright and trademark registration applications, may not be allowed or competitors may challenge the validity or scope of our patents, copyrights or trademarks. In addition, our patents, copyrights, trademarks and other intellectual property rights may not provide us a significant competitive advantage. Over the past few years, we have noticed an increasing tendency for participants in our markets to use conflicts over and challenges to intellectual property as a means to compete. Patent and trademark challenges increase our costs to develop, engineer and market our products. We may need to spend significant resources monitoring our intellectual property rights and we may or may not be able to detect infringement by third parties. If we fail to successfully enforce our intellectual property rights or register new patents, our competitive position could suffer, which could harm our business, financial condition, results of operations and cash flows.

We have significant goodwill and intangible assets and future impairment of our goodwill and intangible assets could have a material negative impact on our financial results.

We test goodwill and indefinite-lived intangible assets for impairment on at least an annual basis, and more frequently if circumstances warrant, by comparing the estimated fair value of each of our reporting units to their respective carrying values on their balance sheets. As of December 31, 2016 our goodwill and intangible assets were $5,849.2 million and represented 51% of our total assets. Long-term declines in projected future cash flows could result in future goodwill and intangible asset impairments.

We may be adversely affected by work stoppages, union negotiations, labor disputes and other matters associated with our labor force.

As of December 31, 2016, approximately 9,000 of our employees were covered by collective bargaining agreements or works councils. Although we believe that our relations with the labor unions and work councils that represent our employees are generally good and we have experienced no material strikes and only minor work stoppages recently, no assurances can be made that we will not experience in the future these and other types of conflicts with labor unions, works councils, other groups representing employees or our employees generally, or that any future negotiations with our labor unions will not result in significant increases in our cost of labor.

Seasonality of sales and weather conditions may adversely affect our financial results.

We experience seasonal demand in a number of markets within Flow & Filtration Solutions, Water Quality Systems and Technical Solutions. In Flow & Filtration Solutions, demand for residential water supply products, infrastructure and agricultural products follows warm weather trends and is at seasonal highs from April to August. In Water Quality Systems, end-user demand for pool equipment in our primary markets follows warm weather trends and is at seasonal highs from April to August. The magnitude of the sales increase in both Flow & Filtration Solutions and Water Quality Systems is partially mitigated by employing some advance sale or "early buy" programs (generally including extended payment terms and/or additional discounts). Seasonal effects may vary from year to year and are impacted by weather patterns, particularly by temperatures, heavy flooding and droughts. Technical Solutions generally experiences increased demand for thermal protection products and services during the fall and winter months in the Northern Hemisphere and increased demand for electrical fastening products during the spring and summer months in the Northern Hemisphere. We cannot provide assurance that seasonality and weather conditions will not have a material adverse effect on our results of operations.

Our share price may fluctuate significantly.

We cannot predict the prices at which our shares may trade. The market price of our shares may fluctuate widely, depending on many factors, some of which may be beyond our control, including:


•	actual or anticipated fluctuations in our operating results due to factors related to our business;


•	success or failure of our business strategy;


•	our quarterly or annual earnings, or those of other companies in our industry;


•	our ability to obtain third-party financing as needed;


•	announcements by us or our competitors of significant acquisitions or dispositions;


•	changes in accounting standards, policies, guidance, interpretations or principles;


•	changes in earnings estimates by us or securities analysts or our ability to meet those estimates;


•	the operating and share price performance of other comparable companies;


•	investor perception of us;


•	natural or other environmental disasters that investors believe may affect us;


•	overall market fluctuations;


•	results from any material litigation, including asbestos claims, government investigations or environmental liabilities;


•	changes in laws and regulations affecting our business; and


•	general economic conditions and other external factors.

Stock markets in general have experienced volatility that has often been unrelated to the operating performance of a particular company. These broad market fluctuations could adversely affect the trading price of our shares.

Risks Relating to Legal, Regulatory and Compliance Matters

Our subsidiaries are party to asbestos-related product litigation that could adversely affect our financial condition, results of operations and cash flows.

Our subsidiaries, along with numerous other companies, are named as defendants in a substantial number of lawsuits based on alleged exposure to asbestos-containing materials. These cases typically involve product liability claims based primarily on allegations of manufacture, sale or distribution of industrial products that either contained asbestos or were attached to or used with asbestos-containing components manufactured by third parties. Each case typically names between dozens to hundreds of corporate defendants. Historically, our subsidiaries have been identified as defendants in asbestos-related claims. We have experienced an increase in the number of asbestos-related lawsuits over the past several years, including lawsuits by plaintiffs with mesothelioma-related claims. A large percentage of these suits have not presented viable legal claims and, as a result, have been dismissed or withdrawn. Our strategy has been, and continues to be, to mount a vigorous defense aimed at having unsubstantiated suits dismissed, and, only where appropriate, settling claims before trial. As of December 31, 2016, there were approximately 3,800 claims pending against our subsidiaries, of which approximately 3,300 relate to the Valves & Controls business classified as held for sale. We cannot predict with certainty the extent to which we will be successful in litigating or

otherwise resolving lawsuits in the future and we continue to evaluate different strategies related to asbestos claims filed against us including entity restructuring and judicial relief. Unfavorable rulings, judgments or settlement terms could have a material adverse impact on our business and financial condition, results of operations and cash flows.

We could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar anti-corruption laws outside the United States.

The FCPA and similar anti-corruption laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials or other persons for the purpose of obtaining or retaining business. Recent years have seen a substantial increase in anti-bribery law enforcement activity, with more frequent and aggressive investigations and enforcement proceedings by both the U.S. Department of Justice ("DOJ") and the SEC, increased enforcement activity by non-U.S. regulators and increases in criminal and civil proceedings brought against companies and individuals. Our policies mandate compliance with these anti-bribery laws. We operate in many parts of the world that are recognized as having governmental and commercial corruption and in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. Because many of our customers and end users are involved in infrastructure construction and energy production, they are often subject to increased scrutiny by regulators. We cannot assure you that our internal control policies and procedures will always protect us from reckless or criminal acts committed by our employees or third-party intermediaries. In the event that we believe or have reason to believe that our employees or agents have or may have violated applicable anti-corruption laws, including the FCPA we may be required to investigate or have outside counsel investigate the relevant facts and circumstances, which can be expensive and require significant time and attention from senior management. Violations of these laws may result in criminal or civil sanctions, which could disrupt our business and result in a material adverse effect on our reputation, business, financial condition, results of operations and cash flows.

Prior to the Merger, the Flow Control business was subject to investigations by the DOJ and the SEC related to allegations that improper payments were made by the Flow Control business and other Tyco subsidiaries and third-party intermediaries in recent years in violation of the FCPA. Tyco reported to the DOJ and the SEC the remedial measures that it had taken in response to the allegations and Tyco's own internal investigations. As a result of discussions with the DOJ and SEC aimed at resolving these matters, on September 24, 2012, Tyco entered into a settlement with the SEC and a non-prosecution agreement with the DOJ. As a result, the Flow Control business may be subject to investigations in other jurisdictions or suffer other criminal or civil penalties or adverse impacts, including being subject to lawsuits brought by private litigants, each of which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our failure to satisfy international trade compliance regulations may adversely affect us.

Our global operations require importing and exporting goods and technology across international borders on a regular basis. Certain of the products we manufacture are "dual use" products, which are products that may have both civil and military applications, or may otherwise be involved in weapons proliferation, and are often subject to more stringent export controls. From time to time, we obtain or receive information alleging improper activity in connection with imports or exports. Our policy mandates strict compliance with U.S. and non-U.S. trade laws applicable to our products. However, even when we are in strict compliance with law and our policies, we may suffer reputational damage if certain of our products are sold through various intermediaries to entities operating in sanctioned countries. When we receive information alleging improper activity, our policy is to investigate that information and respond appropriately, including, if warranted, reporting our findings to relevant governmental authorities. Nonetheless, we cannot provide assurance that our policies and procedures will always protect us from actions that would violate U.S. and/or non-U.S. laws. Any improper actions could subject us to civil or criminal penalties, including material monetary fines, or other adverse actions including denial of import or export privileges, and could damage our reputation and business prospects.

We are exposed to potential environmental and other laws, liabilities and litigation.

We are subject to U.S. federal, state, local and non-U.S. laws and regulations governing our environmental practices, public and worker health and safety, and the indoor and outdoor environment. Compliance with these environmental, health and safety regulations could require us to satisfy environmental liabilities, increase the cost of manufacturing our products or otherwise adversely affect our business, financial condition and results of operations. Any violations of these laws by us could cause us to incur unanticipated liabilities that could harm our operating results and cause our business to suffer. We are also required to comply with various environmental laws and maintain permits, some of which are subject to discretionary renewal from time to time, for many of our businesses and we could suffer if we are unable to renew existing permits or to obtain any additional permits that we may require. Compliance with environmental requirements also could require significant operating or capital expenditures or result in significant operational restrictions. We cannot assure you that we have been or will be at all times in compliance with environmental and health and safety laws. If we violate these laws, we could be fined, criminally charged or otherwise sanctioned by regulators.

We have been named as defendant, target or a potentially responsible party ("PRP") in a number of environmental clean-ups relating to our current or former business units. We have disposed of a number of businesses in recent years and in certain cases, we have retained responsibility and potential liability for certain environmental obligations. We have received claims for indemnification from certain purchasers. We may be named as a PRP at other sites in the future for existing business units, as well as both divested and acquired businesses. In addition to cleanup actions brought by governmental authorities, private parties could bring personal injury or other claims due to the presence of, or exposure to, hazardous substances.

Certain environmental laws impose liability on current or previous owners or operators of real property for the cost of removal or remediation of hazardous substances at their properties or at properties at which they have disposed of hazardous substances. We have projects underway at several current and former manufacturing facilities to investigate and remediate environmental contamination resulting from our past operations or by other businesses that previously owned or used the properties. The cost of cleanup and other environmental liabilities can be difficult to accurately predict. In addition, environmental requirements change and tend to become more stringent over time. Thus, we cannot provide assurance that our eventual environmental clean-up costs and liabilities will not exceed the amount of our current reserves.

We are exposed to potential regulatory, financial and reputational risks related to certain "conflict minerals."

In 2012, the SEC adopted disclosure requirements related to certain minerals sourced from the Democratic Republic of Congo or adjoining countries, as required by Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act. The final rules impose inquiry, diligence and disclosure obligations with respect to "conflict minerals," defined as tin, tantalum, tungsten and gold, that are necessary to the functionality of a product manufactured, or contracted to be manufactured, by an SEC reporting company. Certain of these minerals are used extensively in components manufactured by our suppliers (or in components incorporated by our suppliers into components supplied to us) for use in our products. Under the final rules, an SEC reporting company must conduct a country of origin inquiry that is reasonably designed to determine whether any of the "conflict minerals" that are necessary to the functionality of a product manufactured, or contracted to be manufactured, by the company originated in the Democratic Republic of the Congo or an adjoining country. If any such "conflict minerals" originated in the Democratic Republic of Congo or an adjoining country, the final rules require the issuer to exercise due diligence on the source of such "conflict minerals" and their chain of custody with the ultimate objective of determining whether the "conflict minerals" directly or indirectly financed or benefited armed groups in the Democratic Republic of the Congo or an adjoining country. The issuer must then prepare and file with the SEC annually a report regarding its diligence efforts, which we have done since the SEC's reporting requirements became effective. We have incurred, and expect to continue to incur, significant costs to conduct country of origin inquiries and to exercise such due diligence.

We have a very large number of suppliers and our supply chain is very complex and multifaceted. While we have no intention to use minerals sourced from the Democratic Republic of Congo or adjoining countries that are not "conflict free" (meaning that they do not contain "conflict minerals" that directly or indirectly finance or benefit armed groups in the Democratic Republic of the Congo or an adjoining country), a significant number of our suppliers are small businesses, and those small businesses have limited or no resources to track their sources of minerals. As a result, we have experienced, and expect to continue to experience, ongoing significant difficulty in determining the country of origin or the source and chain of custody for all "conflict minerals" used in our products and disclosing that our products are "conflict free." We may face reputational challenges if we are unable to verify the country of origin or the source and chain of custody for all "conflict minerals" used in our products or if we continue to be unable to disclose that our products are "conflict free." The ongoing implementation of these rules may also affect the sourcing and availability of some minerals necessary to the manufacture of our products and may affect the availability and price of "conflict minerals" capable of certification as "conflict free." Accordingly, we have incurred, and expect to continue to incur, significant costs as a consequence of these rules, which may adversely affect our business, financial condition or results of operations.

We are exposed to certain regulatory and financial risks related to climate change.

Climate change is receiving ever increasing attention worldwide. Many scientists, legislators and others attribute global warming to increased levels of greenhouse gases, including carbon dioxide, which has led to significant legislative and regulatory efforts to limit greenhouse gas emissions. The U.S. Congress and federal and state regulatory agencies have been considering legislation and regulatory proposals that would regulate and limit greenhouse gas emissions. It is uncertain whether, when and in what form a federal mandatory carbon dioxide emissions reduction program may be adopted. Similarly, certain countries have adopted the Kyoto Protocol and this and other existing international initiatives or those under consideration could affect our international operations. To the extent our customers, particularly those involved in the oil and gas, power generation, petrochemical processing or petroleum refining industries, are subject to any of these or other similar proposed or newly enacted laws and regulations, we are exposed to risks that the additional costs by customers to comply with such laws and regulations could impact their ability or desire to continue to operate at similar levels in certain jurisdictions as historically seen or as currently anticipated, which could negatively impact their demand for our products and services. In addition, new laws and regulations that might favor the increased use of non-fossil fuels, including nuclear, wind, solar and bio-fuels or that are designed to increase energy efficiency, could dampen demand for oil and gas production or power generation

resulting in lower spending by customers for our products and services. These actions could also increase costs associated with our operations, including costs for raw materials and transportation. Because it is uncertain what laws will be enacted, we cannot predict the potential impact of such laws on our future financial condition, results of operations and cash flows.

Increased information technology security threats and more sophisticated computer crime pose a risk to our systems, networks, products and services. We are exposed to potential regulatory, financial and reputational risks relating to the protection of our data.

We rely upon information technology systems and networks in connection with a variety of business activities, some of which are managed by third parties. Additionally, we collect and store data that is sensitive to Pentair and its employees, customers, dealers and suppliers. The secure operation of these information technology systems and networks, and the processing and maintenance of this data is critical to our business operations and strategy. Information technology security threats -- from user error to attacks designed to gain unauthorized access to our systems, networks and data -- are increasing in frequency and sophistication. Attacks may range from random attempts to coordinated and targeted attacks, including sophisticated computer crime and advanced persistent threats. These threats pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of the data we process and maintain. Establishing systems and processes to address these threats and changes in legal requirements relating to data collection and storage may increase our costs. We have identified attempts to gain unauthorized access to our information technology systems and networks. To our knowledge, no such attack was ultimately successful in exporting sensitive data or controlling sensitive systems or networks. Should such an attack succeed it could expose us and our employees, customers, dealers and suppliers to misuse of information or systems, the compromising of confidential information, theft of assets, manipulation and destruction of data, defective products, production downtimes and operations disruptions, and breach of privacy, which may require notification under data privacy and other applicable laws. The occurrence of any of these events could adversely affect our reputation, competitive position, business and results of operations. In addition, such breaches in security could result in litigation, regulatory action and potential liability and the costs and operational consequences of implementing further data protection measures.

Our results of operations may be negatively impacted by litigation.

Our businesses expose us to potential litigation, such as product liability claims relating to the design, manufacture and sale of our products. While we currently maintain what we believe to be suitable product liability insurance, we cannot provide assurance that we will be able to maintain this insurance on acceptable terms or that this insurance will provide adequate protection against potential or previously existing liabilities. In addition, we self-insure a portion of product liability claims. Successful claims against us for significant amounts could materially and adversely affect our product reputation, financial condition, results of operations and cash flows.

We share responsibility for certain income tax liabilities for tax periods prior to and including the date of the Distribution.

In connection with the Distribution, we entered into a tax sharing agreement (the "2012 Tax Sharing Agreement") with Tyco (now known as Johnson Controls International plc, "Johnson Controls") and The ADT Corporation ("ADT"), which governs the rights and obligations of ADT, Johnson Controls and us for certain pre-Distribution tax liabilities, including Johnson Controls' obligations under a separate tax sharing agreement (the "2007 Tax Sharing Agreement") entered into by Johnson Controls, Covidien Ltd. (now known as Medtronic plc, "Medtronic") and TE Connectivity Ltd. ("TE Connectivity") in connection with the 2007 distributions of Medtronic and TE Connectivity by Johnson Controls.

The 2012 Tax Sharing Agreement provides that we, Johnson Controls and ADT will share (i) certain pre-Distribution income tax liabilities that arise from adjustments made by tax authorities to our, Johnson Controls' and ADT's U.S. income tax returns, including withholding tax, income tax, or other tax liabilities that could arise if the Merger, Distribution or certain internal transactions undertaken in anticipation of the Distribution are determined to be taxable for U.S. federal or Swiss tax purposes, and (ii) payments required to be made by Johnson Controls with respect to the 2007 Tax Sharing Agreement (the liabilities in clauses (i) and (ii) collectively, "Shared Tax Liabilities"). Johnson Controls is responsible for the first $500 million of Shared Tax Liabilities. As of December 31, 2016, Johnson Controls has paid $210.0 million of Shared Tax Liabilities. We and ADT will share 42% and 58%, respectively, of the next $225 million of Shared Tax Liabilities. We, ADT and Johnson Controls will share 20%, 27.5% and 52.5%, respectively, of Shared Tax Liabilities above $725 million. Costs and expenses associated with the management of Shared Tax Liabilities will generally be shared 20% by us, 27.5% by ADT and 52.5% by Johnson Controls. As of December 31, 2016, we have a liability of $13.3 million recorded for this matter in Other non-current liabilities in the Consolidated Balance Sheets. However, the ultimate resolution of these matters, and the impact of that resolution, are uncertain. To the extent we are responsible for any liability under the 2012 Tax Sharing Agreement, and indirectly the 2007 Tax Sharing Agreement, in excess of the recorded liability, there could be a material adverse impact on our financial condition, results of operations, cash flows or our effective tax rate in future reporting periods.

failure is not the result of actions taken after the Distribution by us, ADT or Johnson Controls, then we, ADT and Johnson Controls would be responsible for any taxes imposed as a result of such determination in the same manner and in the same proportions as we, ADT and Johnson Controls are responsible for Shared Tax Liabilities. Such tax amounts could be significant.

Risks Relating to Our Liquidity

Disruptions in the financial markets could adversely affect us, our customers and our suppliers by increasing funding costs or reducing availability of credit.

In the normal course of our business, we may access credit markets for general corporate purposes, which may include repayment of indebtedness, acquisitions, additions to working capital, repurchase of shares, capital expenditures and investments in our subsidiaries. Although we expect to have sufficient liquidity to meet our foreseeable needs, our access to and the cost of capital could be negatively impacted by disruptions in the credit markets, which have occurred in the past and made financing terms for borrowers unattractive or unavailable. These factors may make it more difficult or expensive for us to access credit markets if the need arises. In addition, these factors may make it more difficult for our suppliers to meet demand for their products or for prospective customers to commence new projects, as customers and suppliers may experience increased costs of debt financing or difficulties in obtaining debt financing. Disruptions in the financial markets have had adverse effects on other areas of the economy and have led to a slowdown in general economic activity that may continue to adversely affect our businesses. These disruptions may have other unknown adverse effects. One or more of these factors could adversely affect our business, financial condition, results of operations or cash flows.

Covenants in our debt instruments may adversely affect us.

Our credit agreements and indentures contain customary financial covenants, including those that limit the amount of our debt, which may restrict the operations of our business and our ability to incur additional debt to finance acquisitions. Our ability to meet the financial covenants can be affected by events beyond our control, and we cannot provide assurance that we will meet those tests. A breach of any of these covenants could result in a default under our credit agreements or indentures. Upon the occurrence of an event of default under any of our credit facilities or indentures, the lenders or trustees could elect to declare all amounts outstanding thereunder to be immediately due and payable and, in the case of credit facility lenders, terminate all commitments to extend further credit. If the lenders or trustees accelerate the repayment of borrowings, we cannot provide assurance that we will have sufficient assets to repay our credit facilities and our other indebtedness. Furthermore, acceleration of any obligation under any of our material debt instruments will permit the holders of our other material debt to accelerate their obligations, which could have a material adverse effect on our financial condition.

We may increase our debt or raise additional capital in the future, which could affect our financial condition, and may decrease our profitability.

As of December 31, 2016, we had $4.3 billion of total debt outstanding. We may increase our debt or raise additional capital in the future, subject to restrictions in our debt agreements. If our cash flow from operations is less than we anticipate, if our cash requirements are more than we expect, or if we intend to finance acquisitions, we may require more financing. However, debt or equity financing may not be available to us on acceptable terms, if at all. If we incur additional debt or raise equity through the issuance of additional capital shares, the terms of the debt or capital shares issued may give the holders rights, preferences and privileges senior to those of holders of our ordinary shares, particularly in the event of liquidation. The terms of the debt may also impose additional and more stringent restrictions on our operations than we currently have. If we raise funds through the issuance of additional equity, the percentage ownership of existing shareholders in our company would decline. If we are unable to raise additional capital when needed, our financial condition could be adversely affected.

Our leverage could have a material adverse effect on our business, financial condition or results of operations.

Our ability to make payments on and to refinance our indebtedness, including our existing debt as well as any future debt that we may incur, will depend on our ability to generate cash in the future from operations, financings or asset sales. Our ability to generate cash is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. If we are not able to repay or refinance our debt as it becomes due, we may be forced to sell assets or take other disadvantageous actions, including (i) reducing financing in the future for working capital, capital expenditures and general corporate purposes or (ii) dedicating an unsustainable level of our cash flow from operations to the payment of principal and interest on our indebtedness. The lenders who hold such debt could also accelerate amounts due, which could potentially trigger a default or acceleration of any of our other debt.

Risks Relating to Our Jurisdiction of Incorporation in Ireland and Tax Residency in the United Kingdom

We are subject to changes in law and other factors that may not allow us to maintain a worldwide effective corporate tax rate that is competitive in our industry.

While we believe that we should be able to maintain a worldwide effective corporate tax rate that is competitive in our industry, we cannot give any assurance as to what our effective tax rate will be in the future because of, among other things, uncertainty regarding tax policies of the jurisdictions where we operate. Also, the tax laws of the U.S., the U.K., Ireland and other jurisdictions could change in the future, and such changes could cause a material change in our worldwide effective corporate tax rate. In particular, legislative action could be taken by the U.S., the U.K., Ireland or the European Union which could override tax treaties or modify tax statutes or regulations upon which we expect to rely and adversely affect our effective tax rate. We cannot predict the outcome of any specific legislative proposals. If proposals were enacted that had the effect of disregarding our incorporation in Ireland or limiting our ability as an Irish company to maintain tax residency in the U.K. and take advantage of the tax treaties among the U.S., the U.K. and Ireland, we could be subject to increased taxation, which could materially adversely affect our financial condition, results of operations, cash flows or our effective tax rate in future reporting periods.

A change in our tax residency could have a negative effect on our future profitability and taxes on dividends.

Under current Irish legislation, a company is regarded as resident for tax purposes in Ireland if it is centrally managed and controlled in Ireland, or, in certain circumstances, if it is incorporated in Ireland. Under current U.K. legislation, a company that is centrally managed and controlled in the U.K. is regarded as resident in the U.K. for taxation purposes. Where a company is treated as tax resident under the domestic laws of both the U.K. and Ireland then the provisions of article 4(3) of the Double Tax Convention between Ireland and the U.K. provide that such enterprise shall be treated as resident only in the jurisdiction in which its place of effective management is situated. We have managed, and we intend to continue to manage, our affairs so that we are centrally managed and controlled in the U.K. and therefore have our tax residency only in the U.K. However, we cannot provide assurance that we will continue to be resident only in the U.K. for tax purposes. It is possible that in the future, whether as a result of a change in law or the practice of any relevant tax authority or as a result of any change in the conduct of its affairs, we could become, or be regarded as having become resident in a jurisdiction other than the U.K. If we were considered to be a tax resident of Ireland, we could become liable for Irish corporation tax and any dividends paid by us could be subject to Irish dividend withholding tax.

Irish law differs from the laws in effect in the United States and may afford less protection to holders of our securities.

It may not be possible to enforce court judgments obtained in the U.S. against us in Ireland based on the civil liability provisions of the U.S. federal or state securities laws. In addition, there is some uncertainty as to whether the courts of Ireland would recognize or enforce judgments of U.S. courts obtained against us or our directors or officers based on the civil liabilities provisions of the U.S. federal or state securities laws or hear actions against us or those persons based on those laws. We have been advised that the United States currently does not have a treaty with Ireland providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. Therefore, a final judgment for the payment of money rendered by any U.S. federal or state court based on civil liability, whether or not based solely on U.S. federal or state securities laws, would not automatically be enforceable in Ireland.

As an Irish company, we are governed by the Irish Companies Act, which differs in some material respects from laws generally applicable to U.S. corporations and shareholders, including, among others, differences relating to interested director and officer transactions and shareholder lawsuits. Likewise, the duties of directors and officers of an Irish company generally are owed to the company only. Shareholders of Irish companies generally do not have a personal right of action against directors or officers of the company and may exercise such rights of action on behalf of the company only in limited circumstances. Accordingly, holders of our securities may have more difficulty protecting their interests than would holders of securities of a corporation incorporated in a jurisdiction of the U.S.

Transfers of our ordinary shares may be subject to Irish stamp duty.

Transfers of our ordinary shares effected by means of the transfer of book entry interests in the Depository Trust Company ("DTC") will not be subject to Irish stamp duty. However, if you hold your ordinary shares directly rather than beneficially through DTC, any transfer of your ordinary shares could be subject to Irish stamp duty (currently at the rate of 1% of the higher of the price paid or the market value of the shares acquired). Payment of Irish stamp duty is generally a legal obligation of the transferee.

We currently intend to pay, or cause one of our affiliates to pay, stamp duty in connection with share transfers made in the ordinary course of trading by a seller who holds shares directly to a buyer who holds the acquired shares beneficially. In other cases we may, in our absolute discretion, pay or cause one of our affiliates to pay any stamp duty. Our articles of association provide that, in the event of any such payment, we (i) may seek reimbursement from the buyer, (ii) will have a lien against the shares acquired by such buyer and any dividends paid on such shares and (iii) may set-off the amount of the stamp duty against

future dividends on such shares. Parties to a share transfer may assume that any stamp duty arising in respect of a transaction in our shares has been paid unless one or both of such parties is otherwise notified by us.

Our ordinary shares, received by means of a gift or inheritance could be subject to Irish capital acquisitions tax.

Irish capital acquisitions tax ("CAT") could apply to a gift or inheritance of our ordinary shares irrespective of the place of residence, ordinary residence or domicile of the parties. This is because our shares will be regarded as property situated in Ireland. The person who receives the gift or inheritance has primary liability for CAT. Gifts and inheritances passing between spouses are exempt from CAT. Children have a tax-free threshold of €310,000 per lifetime in respect of taxable gifts or inheritances received from their parents for periods on or after October 12, 2016.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

Our principal office is located in leased premises in London, United Kingdom, and our management office in the United States is located in leased premises in Minneapolis, Minnesota. Our operations are conducted in facilities throughout the world.

In addition, Technical Solutions has 16 distribution facilities, 52 sales offices and 3 service centers located in numerous countries throughout the world.

We believe that our production facilities are suitable for their purpose and are adequate to support our businesses.

ITEM 3. LEGAL PROCEEDINGS

We have been made parties to a number of actions filed or have been given notice of potential claims relating to the conduct of our business, including those pertaining to commercial disputes, product liability, asbestos, environmental, safety and health, patent infringement and employment matters.

While we believe that a material impact on our consolidated financial position, results of operations or cash flows from any such future claims or potential claims is unlikely, given the inherent uncertainty of litigation, a remote possibility exists that a future adverse ruling or unfavorable development could result in future charges that could have a material adverse impact. We do and will continue to periodically reexamine our estimates of probable liabilities and any associated expenses and receivables and make appropriate adjustments to such estimates based on experience and developments in litigation. As a result, the current estimates of the potential impact on our consolidated financial position, results of operations and cash flows for the proceedings and claims described in the notes to our consolidated financial statements could change in the future.

Asbestos matters

Our subsidiaries and numerous other companies are named as defendants in personal injury lawsuits based on alleged exposure to asbestos-containing materials. These cases typically involve product liability claims based primarily on allegations of manufacture, sale or distribution of industrial products that either contained asbestos or were attached to or used with asbestos-containing components manufactured by third-parties. Each case typically names between dozens to hundreds of corporate defendants. While we have observed an increase in the number of these lawsuits over the past several years, including lawsuits by plaintiffs with mesothelioma-related claims, a large percentage of these suits have not presented viable legal claims and, as a result, have been dismissed by the courts. Our historical strategy has been to mount a vigorous defense aimed at having unsubstantiated suits dismissed, and, where appropriate, settling suits before trial. Although a large percentage of litigated suits have been dismissed, we cannot predict the extent to which we will be successful in resolving lawsuits in the future.

As of December 31, 2016, there were approximately 3,800 claims outstanding against our subsidiaries, of which approximately 3,300 relate to the Valves & Controls business classified as held for sale. This amount is not adjusted for claims that are not actively being prosecuted, identified incorrect defendants, or duplicated other actions, which would ultimately reflect our current estimate of the number of viable claims made against us, our affiliates, or entities for which we assumed responsibility in connection with acquisitions or divestitures. In addition, the amount does not include certain claims pending against third parties for which we have been provided an indemnification.

Our estimated liability for asbestos-related claims was $228.3 million and $237.9 million as of December 31, 2016 and 2015, respectively, and was recorded in Non-current liabilities held for sale in the Consolidated Balance Sheets for pending and future claims and related defense costs. Our estimated receivable for insurance recoveries was $108.5 million and $111.0 million, respectively, at December 31, 2016 and 2015, and was recorded in Non-current assets held for sale in the Consolidated Balance Sheets.

Environmental matters

We are involved in or have retained responsibility and potential liability for environmental obligations and legal proceedings related to our current business and, including pursuant to certain indemnification obligations, related to certain formerly owned businesses. We are responsible, or alleged to be responsible, for ongoing environmental investigation and/or remediation of sites in several countries. These sites are in various stages of investigation and/or remediation and at some of these sites our liability is considered de minimis. We received notification from the U.S. Environmental Protection Agency and from similar state and non-U.S. environmental agencies that several sites formerly or currently owned and/or operated by us, and other properties or water supplies that may be or may have been impacted from those operations, contain disposed or recycled materials or waste and require environmental investigation and/or remediation. Those sites include instances where we have been identified as a potentially responsible party under U.S. federal, state and/or non-U.S. environmental laws and regulations. For several formerly owned businesses, we have also received claims for indemnification from purchasers of these businesses.

Our accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. It can be difficult to estimate reliably the final costs of investigation and remediation due to various factors. In our opinion, the amounts accrued are appropriate based on facts and circumstances as currently known. Based upon our experience, current information regarding known contingencies and applicable laws, we have recorded reserves for these environmental matters of $18.3 million and $22.8 million as of December 31, 2016 and 2015, respectively, which relate primarily to the Valves & Controls business classified as held for sale. We do not anticipate these environmental conditions will have a material adverse effect on our financial position, results of operations or cash flows. However, unknown conditions, new details about existing conditions or changes in environmental requirements may give rise to environmental liabilities that will exceed the amount of our current reserves and could have a material adverse effect in the future.

Product liability claims

We are subject to various product liability lawsuits and personal injury claims. A substantial number of these lawsuits and claims are insured and accrued for by Penwald, our captive insurance subsidiary. See discussion in ITEM 1 and ITEM 8, Note 1 of the Notes to Consolidated Financial Statements — Insurance subsidiary. Penwald records a liability for these claims based on actuarial projections of ultimate losses. For all other claims, accruals covering the claims are recorded, on an undiscounted basis, when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on existing information. The accruals are adjusted periodically as additional information becomes available. We have not experienced significant unfavorable trends in either the severity or frequency of product liability lawsuits or personal injury claims.

PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our ordinary shares are listed for trading on the New York Stock Exchange and trade under the symbol "PNR." As of December 31, 2016, there were 18,840 shareholders of record.

The high, low and closing sales price for our ordinary shares and the dividends paid for each of the quarterly periods for 2016 and 2015 were as follows:



	2016								2015
	First		Second		Third		Fourth		First		Second		Third		Fourth
High	$	54.54	$	63.39	$	66.99	$	64.39	$	68.24	$	66.52	$	69.65	$	59.69
Low	41.57		50.37		57.20		53.80		60.73		59.92		49.44		48.14
Close	54.26		58.29		64.24		56.07		62.39		63.75		51.98		49.53
Dividends paid	0.33		0.33		0.34		0.34		0.32		0.32		0.32		0.32

Pentair has paid 164 consecutive quarterly dividends. The Board of Directors has approved a plan to increase the dividend for 2017, which will mark the 41^st consecutive year we have increased dividends.

Future dividends on our ordinary shares or reductions of share capital for distribution to shareholders, if any, must be approved by our Board of Directors for payment out of distributable reserves on our statutory balance sheet. We are not permitted to pay dividends out of share capital, which includes share premiums. Distributable reserves may be created through the earnings of the Irish parent company and through a reduction in share capital approved by the Irish High Court. Distributable reserves are not linked to a U.S. generally accepted accounting principles ("GAAP") reported amount (e.g., retained earnings). On July 22, 2014, the Irish High Court approved Pentair plc's conversion of approximately $14.4 billion of share premium to distributable reserves. On July 29, 2014, following the approval of the Irish High Court, we made the required filing of Pentair plc's initial accounts with the Irish Companies Registration Office, which completed the process to allow us to pay future cash dividends and redeem and repurchase shares out of Pentair plc's "distributable reserves." Our distributable reserve balance was $9.4 billion and $9.6 billion as of December 31, 2016 and 2015, respectively.

The timing, declaration and payment of future dividends to holders of our ordinary shares will depend upon many factors, including our financial condition and results of operations, the capital requirements of our businesses, industry practice and any other relevant factors.

United Kingdom tax considerations

Although our jurisdiction of organization is Ireland, we manage our affairs so that we are centrally managed and controlled in the U.K. and therefore have our tax residency in the U.K.

As a result of its U.K. tax status, dividend distributions by Pentair plc to its shareholders are not subject to withholding tax, as the U.K. currently does not levy a withholding tax on dividend distributions.

See the discussion of "Dividends" under "Liquidity and Capital Resources—Financing Activities" in ITEM 7 of this annual report on Form 10-K for additional information required by this item.

Share Performance Graph

The following information under the caption "Share Performance Graph" in this ITEM 5 of this Annual Report on Form 10-K is not deemed to be "soliciting material" or to be "filed" with the SEC or subject to Regulation 14A or 14C under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or to the liabilities of Section 18 of the Exchange Act and will not be deemed to be incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except to the extent we specifically incorporate it by reference into such a filing.

The following graph sets forth the cumulative total shareholder return on our ordinary shares for the last five years, assuming the investment of $100 on December 31, 2011 and the reinvestment of all dividends since that date to December 31, 2016. The graph also contains for comparison purposes the S&P 500 Index and the S&P 500 Industrials Index, assuming the same investment level and reinvestment of dividends.

By virtue of our market capitalization, we are a component of the S&P 500 Index. On the basis of our size and diversity of businesses, we believe the S&P 500 Industrials Index is an appropriate published industry index for comparison purposes.

Overview

Pentair plc is a focused diversified industrial manufacturing company comprising three reporting segments: Water Quality Systems, Flow & Filtration Solutions and Technical Solutions. We classify our operations into business segments based primarily on types of products offered and markets served. For the year ended December 31, 2016, Water Quality Systems, Flow & Filtration Solutions and Technical Solutions accounted for 29 percent, 28 percent and 43 percent of total revenues, respectively.

In December 2013, the Company's Board of Directors approved changing the Company's jurisdiction of organization from Switzerland to Ireland. At an extraordinary meeting of shareholders on May 20, 2014, Pentair Ltd. shareholders voted in favor of a reorganization proposal pursuant to which Pentair Ltd. would merge into Pentair plc and all Pentair Ltd. common shares would be cancelled and all holders of such shares would receive ordinary shares of Pentair plc on a one-to-one basis. The reorganization transaction was completed on June 3, 2014, at which time Pentair plc replaced Pentair Ltd. as the ultimate parent company (the "Redomicile"). Shares of Pentair plc began trading on the New York Stock Exchange ("NYSE") on June 3, 2014 under the symbol "PNR", the same symbol under which Pentair Ltd. shares were previously traded.

Our former parent company, Pentair Ltd., took its form on September 28, 2012 as a result of a reverse acquisition (the "Merger") involving Pentair, Inc. and an indirect, wholly-owned subsidiary of Flow Control (defined below), with Pentair, Inc. surviving as an indirect, wholly-owned subsidiary of Pentair Ltd. "Flow Control" refers to Pentair Ltd. prior the Merger. Prior to the Merger, Tyco International Ltd. ("Tyco") engaged in an internal restructuring whereby it transferred to Flow Control certain assets related to the flow control business of Tyco, and Flow Control assumed from Tyco certain liabilities related to the flow control business of Tyco. On September 28, 2012 prior to the Merger, Tyco effected a spin-off of Flow Control through the pro-rata distribution of 100% of the outstanding ordinary shares of Flow Control to Tyco's shareholders (the "Distribution"), resulting in the distribution of approximately 110.9 million of our ordinary shares to Tyco's shareholders. The Merger was accounted for as a reverse acquisition under the purchase method of accounting with Pentair, Inc. treated as the acquirer.

On January 30, 2014, we acquired, as part of Water Quality Systems, the remaining 19.9 percent ownership interest in two entities, a U.S. entity and an international entity (collectively, Pentair Residential Filtration or "PRF"), from GE Water & Process Technologies (a unit of General Electric Company) ("GE") for $134.3 million in cash. Prior to the acquisition, we held a 80.1 percent ownership equity interest in PRF, representing our and GE's respective global water softener and residential water filtration businesses.

On July 28, 2014, our Board of Directors approved a decision to exit our Water Transport business in Australia. The results of the Water Transport business have been presented as discontinued operations and the assets and liabilities of the Water Transport business have been reclassified as held for sale for all periods presented. During 2014, we recognized an impairment charge related to allocated amounts of goodwill, intangible assets, property, plant & equipment and other non-current assets totaling $380.1 million, net of tax, representing our estimated loss on disposal of the Water Transport business. The sale of the Water Transport business was completed in 2015.

On September 18, 2015, we acquired, as part of Technical Solutions, all of the outstanding shares of capital stock of ERICO Global Company ("ERICO") for approximately 1.8 billion (the "ERICO Acquisition"). ERICO is a leading global manufacturer and marketer of engineered electrical and fastening products for electrical, mechanical and civil applications. ERICO has employees in 30 countries across the world with recognized brands including CADDY fixing, fastening and support products; ERICO electrical grounding, bonding and connectivity products and LENTON engineered systems.

Key trends and uncertainties regarding our existing business

The following trends and uncertainties affected our financial performance in 2016 and 2015, and will likely impact our results in the future:


•	Despite the favorable long-term outlook for our end-markets, we experience differing levels of volatility depending on the end-market and may continue to do so over the medium and longer term. During 2015 and 2016, our core sales have been challenged by broad-based industrial capital expenditure and maintenance deferrals. We expect this trend to continue into 2017.


•	We experienced declines within our industrial and energy businesses. We expect headwinds in the industrial and energy businesses to continue and oil prices to remain depressed into 2017.


•	We initiated restructuring actions to offset the negative earnings impact of core revenue decline and foreign exchange. We expect to continue these actions into 2017 and these actions will contribute to margin growth in 2017.


•	In late 2015 and continuing through 2016, our results were negatively impacted due to the strengthening of the U.S. dollar against most key global currencies. We expect this trend to continue into 2017.

•

We have identified specific product and geographic market opportunities that we find attractive and continue to pursue, both within and outside the United States. We are reinforcing our businesses to more effectively address these opportunities through research and development and additional sales and marketing resources. Unless we successfully penetrate these markets, our core sales growth will likely be limited or may decline.


•	We have experienced material and other cost inflation. We strive for productivity improvements, and we implement increases in selling prices to help mitigate this inflation. We expect the current economic environment will result in continuing price volatility for many of our raw materials, and we are uncertain as to the timing and impact of these market changes.

In 2017, our operating objectives include the following:


•	Reducing long-term debt and overall leverage through improved cash flow performance and the pending sale of the Valves & Controls business;


•	Driving operating excellence through lean enterprise initiatives, with specific focus on sourcing and supply management, cash flow management and lean operations;


•	Achieving differentiated revenue growth through new products and global and market expansion;


•	Optimizing our technological capabilities to increasingly generate innovative new products; and


•	Focusing on developing global talent in light of our global presence.

•	sales of $516.1 million in 2016 as a result of the ERICO Acquisition, compared to sales of $147.0 million in 2015; and


•	core sales growth in Water Quality Systems, primarily as the result of increased volume in the United States and Canada.

These increases were partially offset by:


•	continued slowdown in capital spending, particularly in our industrial and energy businesses, driving core sales declines in Flow & Filtration Solutions and Technical Solutions;


•	slowing economic activity in certain developing regions, including China and Brazil; and


•	a strong U.S. dollar causing unfavorable foreign currency effects.

The 1.1 percent decrease in consolidated net sales in 2015 from 2014 was primarily the result of:


•	a strong U.S. dollar causing unfavorable foreign currency effects;


•	a slowdown in industrial capital spending, particularly in our industrial and infrastructure businesses; and


•	slowing economic activity in China, Brazil and other developing markets.

These decreases were partially offset by:


•	sales of $147.0 million as a result of the ERICO Acquisition;


•	core sales growth in Water Quality Systems and Technical Solutions, primarily as the result of increased volume in the United States and Canada; and


•	core sales growth in our food & beverage and residential & commercial businesses.

Gross profit

The 2.1 percentage point increase in gross profit as a percentage of sales in 2016 from 2015 was primarily the result of:


•	higher sales volumes, which resulted in increased leverage on fixed expenses included in cost of goods sold;


•	higher contribution margin as a result of savings generated from our Pentair Integrated Management System ("PIMS") initiatives including lean and supply management practices; and


•	a decrease in cost of goods sold of $35.7 million in 2016 compared to 2015 as a result of inventory fair value step-up recorded as part of the Technical Solutions acquisitions in 2015.

These increases were partially offset by:


•	inflationary increases related to raw materials and labor costs.

The 0.1 percentage point decrease in gross profit as a percentage of sales in 2015 from 2014 was primarily the result of:


•	an increase in cost of goods sold of $35.7 million in 2015 compared to 2014 as a result of inventory fair value step-up recorded as part of the Technical Solutions acquisitions in 2015; and


•	inflationary increases related to raw materials and labor costs.

These decreases were partially offset by:


•	higher contribution margin as a result of savings generated from our PIMS initiatives including lean and supply management practices.

Selling, general and administrative ("SG&A")

The 0.9 percentage point increase in SG&A expense as a percentage of sales in 2016 from 2015 and was driven by:


•	"mark-to-market" actuarial losses related to pension and other post-retirement benefit plans of $4.2 million in 2016, compared to "mark-to-market" actuarial gains of $23.0 million in 2015;


•	an increase in intangible asset amortization as a result of the ERICO Acquisition that occurred at the end of the third quarter in 2015;


•	a non-cash impairment charge of $13.3 million related to a trade name intangible asset in Technical Solutions; and


•	increased investment in sales and marketing to drive growth.

These increases were partially offset by:


•	restructuring costs of $24.5 million in 2016, compared to $41.3 million in 2015;


•	deal related costs and expenses of $14.3 million in 2015, which did not occur in 2016; and


•	savings generated from back-office consolidation, reduction in personnel and other lean initiatives.

The 2.0 percentage point decrease in SG&A expense as a percentage of sales in 2015 from 2014 and was driven by the following:


•	"mark-to-market" actuarial gains related to pension and other post-retirement benefit plans of $23.0 million in 2015, compared to "mark-to-market" actuarial losses of $31.5 million in 2014;


•	costs of $10.3 million incurred in 2014 as a result of the Redomicile of the Company from Switzerland to Ireland, which did not occur in 2015; and


•	cost savings generated from back-office consolidation, reduction in personnel and other lean initiatives.

These decreases were partially offset by:


•	deal related costs and expenses of $14.3 million in 2015; and


•	lower sales volume and the resultant loss of leverage on fixed operating expenses.

Net interest expense

The 37.5 percent increase in net interest expense in 2016 from 2015 was primarily the result of:


•	the impact of higher debt levels during 2016, compared to 2015, primarily as the result of the September 2015 issuance of senior notes used to finance the ERICO Acquisition; and


•	increased overall interest rates in effect on our outstanding debt.

The 48.5 percent increase in net interest expense in 2015 from 2014 was primarily the result of:


•	the amortization of $10.8 million of debt issuance costs during 2015 related to financing commitments for a senior unsecured bridge loan facility established (and subsequently terminated upon issuance of the September 2015 issuance of senior notes discussed in Liquidity and Capital Resources below) in connection with the ERICO acquisition; and


•	the impact of higher debt levels during 2015, compared to 2014, primarily as the result of the September 2015 issuance of senior notes used to finance the ERICO Acquisition.

Provision for income taxes

The 3.0 percentage point decrease in the effective tax rate in 2016 from 2015 was primarily due to:


•	the mix of global earnings toward lower tax jurisdictions; and


•	the unfavorable tax impact of transaction costs in 2015 related to the ERICO Acquisition.

The 1.8 percentage point decrease in the effective tax rate in 2015 from 2014 was primarily due to:


•	the mix of global earnings toward lower tax jurisdictions; and


•	non-recurring withholding taxes during 2014 which did not recur in 2015.

The decrease was partially offset by:


•	the unfavorable tax impact of transaction costs in 2015 related to the ERICO Acquisition.

SEGMENT RESULTS OF OPERATIONS

This summary that follows provides a discussion of the results of operations of each of our three reportable segments (Water Quality Systems, Flow & Filtration Solutions and Technical Solutions). Each of these segments comprises various product offerings that serve multiple end markets.

We evaluate performance based on sales and segment income and use a variety of ratios to measure performance of our reporting segments. During the third quarter of 2015, we revised our definition of segment income to exclude intangible amortization to better reflect how management assesses performance of the business. Segment income represents equity income of unconsolidated subsidiaries and operating income exclusive of intangible amortization, certain acquisition related expenses, costs of restructuring activities, "mark-to-market" gain/loss for pension and other post-retirement plans, impairments and other unusual non-operating items.

Total	(5.4	)%	(10.1	)%

The 5.4 percent decrease in Flow & Filtration Solutions sales in 2016 from 2015 was primarily the result of:


•	continued slowdown in industrial capital spending, driving core sales declines in our industrial business;


•	core sales declines in the food & beverage business due mainly to weak irrigation sales and lower project sales;


•	continued sales declines in China, Southeast Asia and Brazil as the result of economic uncertainty; and


•	a strong U.S. dollar causing unfavorable foreign currency effects.

These decreases were partially offset by:


•	core sales growth related to higher sales of pump and filtration solutions serving the infrastructure business;


•	core growth in the Middle East; and


•	selective increases in selling prices to mitigate inflationary cost increases.

The 10.1 percent decrease in Flow & Filtration Solutions sales in 2015 from 2014 was primarily the result of:


•	decrease in core sales due to significant declines in the global agricultural industry, broad-based slowing of global capital spending and customer inventory de-stocking;


•	decreased sales volume related to the loss of a customer in the residential retail business during the second half of 2014; and


•	a strong U.S. dollar causing unfavorable foreign currency effects.

LIQUIDITY AND CAPITAL RESOURCES

We generally fund cash requirements for working capital, capital expenditures, equity investments, acquisitions, debt repayments, dividend payments and share repurchases from cash generated from operations, availability under existing committed revolving credit facilities and in certain instances, public and private debt and equity offerings. We have grown our businesses in significant part in the past through acquisitions financed by credit provided under our revolving credit facilities and from time to time, by private or public debt issuance. Our primary revolving credit facilities have generally been adequate for these purposes, although we have negotiated additional credit facilities as needed to allow us to complete acquisitions. We intend to issue commercial paper to fund our financing needs on a short-term basis and to use our revolving credit facility as back-up liquidity to support commercial paper.

We are focusing on increasing our cash flow and repaying existing debt, while continuing to fund our research and development, marketing and capital investment initiatives. Our intent is to maintain investment grade ratings and a solid liquidity position.

We experience seasonal cash flows primarily due to seasonal demand in a number of markets within Flow & Filtration Solutions and Water Quality Systems. We generally borrow in the first quarter of our fiscal year for operational purposes, which usage reverses in the second quarter as the seasonality of our businesses peaks. End-user demand for pool and certain pumping equipment follows warm weather trends and is at seasonal highs from April to August. The magnitude of the sales spike is partially mitigated by employing some advance sale "early buy" programs (generally including extended payment terms and/or

additional discounts). Demand for residential and agricultural water systems is also impacted by weather patterns, particularly by heavy flooding and droughts. Additionally, Technical Solutions generally experiences increased demand for thermal protection products and services during the fall and winter months in the Northern Hemisphere.

Operating activities

Cash provided by operating activities of continuing operations was $702.4 million in 2016, or $104.7 million higher than in 2015. The increase in cash provided by operating activities from continuing operations was due primarily to a $122.6 million increase in Net income from continuing operations, net of the following non-cash items: depreciation and amortization, loss on sale of businesses, trade name impairment and pension and other post-retirement expense.

Cash provided by operating activities from continuing operations was $597.7 million in 2015, or $78.3 million lower than in 2014. The decrease in cash provided by operating activities from continuing operations was due primarily to changes in non-cash pension and other post-retirement expenses and increases in net working capital during 2015.

Investing activities

Net cash used for investing activities of continuing operations was $123.3 million in 2016, compared to $2,003.6 million in 2015 and $93.9 million in 2014. The following investing activities impacted our cash flow:

Acquisitions

In November 2016, we paid cash of $25.0 million to acquire a business as part of Water Quality Systems.

In 2015, we paid cash of $1,806.3 million, net of cash acquired, to acquire ERICO Global Company during the third quarter and cash of $96.0 million, net of cash acquired, to acquire Nuheat Industries Limited ("Nuheat") during the second quarter, both as part of Technical Solutions. During the fourth quarter, we paid an additional $0.9 million related to the Nuheat acquisition in settlement of a working capital adjustment.

In December 2014, we paid cash of $7.5 million and $4.8 million to acquire businesses as part of Water Quality Systems and Technical Solutions, respectively.

Capital expenditures

Capital expenditures in 2016, 2015 and 2014 were $117.8 million, $91.3 million and $83.7 million, respectively. We anticipate capital expenditures for fiscal 2017 to be approximately $100 million, primarily for capacity expansions of manufacturing facilities located in our low-cost countries, developing new products and general maintenance.

Financing activities

Net cash used for financing activities was $600.1 million in 2016. Cash used for financing activities in 2016 was primarily due to net repayments of commercial paper and revolving long-term debt and payment of dividends.

Net cash provided by financing activities was $1,286.3 million in 2015. Cash provided by financing activities in 2015 was primarily due to cash proceeds received from the September 2015 issuance of senior notes (discussed below), partially offset by share repurchases, repayment of $350.0 million of senior notes due 2015 and payment of dividends.

Net cash used for financing activities was $995.1 million in 2014. Cash used for financing activities in 2014 included share repurchases, payments of dividends and the purchase of the remaining noncontrolling interest in a business, partially offset by net receipts of commercial paper and revolving long-term debt to fund our operations in the normal course of business.

In September 2015, Pentair plc, Pentair Finance S.A. ("PFSA") and Pentair Investments Switzerland GmbH ("PISG"), a 100-percent owned subsidiary of Pentair plc and the 100-percent owner of PFSA, completed public offerings (the "September 2015 Offerings") of $500.0 million aggregate principal amount of PFSA's 2.90% Senior Notes due 2018, $400.0 million aggregate principal amount of PFSA's 3.625% Senior Notes due 2020, $250.0 million aggregate principal amount of PFSA's 4.65% Senior Notes due 2025 and €500.0 million aggregate principal amount of PFSA's 2.45% Senior Notes due 2019, all of which are guaranteed as to payment by Pentair plc and PISG. Pentair plc used the net proceeds from the September 2015 Offerings to finance the ERICO Acquisition.

The Senior Notes issued in the September 2015 Offerings, 1.875% Senior Notes due 2017, 2.65% Senior Notes due 2019, $373.0 million of the 5.00% Senior Notes due 2021 and 3.15% Senior Notes due 2022 issued by PFSA and $127.0 million of the 5.00% Senior Notes due 2021 issued by Pentair, Inc. (collectively, the "Notes"), are guaranteed as to payment by Pentair plc and PISG.

In October 2014, Pentair plc, PISG, PFSA and Pentair, Inc. entered into an amended and restated credit agreement (the "Credit Facility"), with Pentair plc and PISG as guarantors and PFSA and Pentair, Inc. as borrowers. The Credit Facility had a maximum aggregate availability to $2,100.0 million and a maturity date of October 3, 2019. Borrowings under the Credit

Facility generally bear interest at a variable rate equal to the London Interbank Offered Rate ("LIBOR") plus a specified margin based upon PFSA's credit ratings. PFSA must pay a facility fee ranging from 9.0 to 25.0 basis points per annum (based upon PFSA's credit ratings) on the amount of each lender's commitment and letter of credit fee for each letter of credit issued and outstanding under the Credit Facility.

In August 2015, Pentair plc, PISG and PFSA entered into a First Amendment to the Credit Facility (the "First Amendment"), which, among other things, increased the Leverage Ratio (as defined below). In September 2015, Pentair plc, PISG and PFSA entered into a Second Amendment to the Credit Facility (the "Second Amendment"), which, among other things, increased the maximum aggregate availability to $2,500.0 million. Additionally, in September 2016, Pentair plc, PISG and PFSA entered into a Third Amendment to the Credit Facility (the "Third Amendment," and collectively with the First Amendment and Second Amendment, the "Amendments"), which, among other things, increased the maximum Leverage Ratio to the amounts specified below, and amended the definition of EBITDA to include earnings from discontinued operations subject to a sale agreement until such disposition actually occurs.

PFSA is authorized to sell short-term commercial paper notes to the extent availability exists under the Credit Facility. PFSA uses the Credit Facility as back-up liquidity to support 100% of commercial paper outstanding. As of December 31, 2016 and 2015, we had $398.7 and $179.5, respectively, of commercial paper outstanding, all of which was classified as long-term as we have the intent and the ability to refinance such obligations on a long-term basis under the Credit Facility.

Our debt agreements contain certain financial covenants, the most restrictive of which are in the Credit Facility (as updated for the Amendments), including that we may not permit (i) the ratio of our consolidated debt plus synthetic lease obligations to our consolidated net income (excluding, among other things, non-cash gains and losses) before interest, taxes, depreciation, amortization, non-cash share-based compensation expense, up to a lifetime maximum $25.0 million of costs, fees and expenses incurred in connection with certain acquisitions, investments, dispositions and the issuance, repayment or refinancing of debt, ("EBITDA") for the four consecutive fiscal quarters then ended (the "Leverage Ratio") to exceed (a) 4.50 to 1.00 as of the last day of any period of four consecutive fiscal quarters ending on September 30, 2016; (b) 4.50 to 1.00 as of the last day of the period of four consecutive fiscal quarters ending on December 31, 2016; (c) 4.25 to 1.00 as of the last day of the period of four consecutive fiscal quarters ending on March 31, 2017; (d) 4.00 to 1.00 as of the last day of the period of four consecutive fiscal quarters ending on June 30, 2017; and (e) 3.50 to 1.00 as of the last day of the period of four consecutive fiscal quarters ending thereafter, and (ii) the ratio of our EBITDA for the four consecutive fiscal quarters then ended to our consolidated interest expense, including consolidated yield or discount accrued as to outstanding securitization obligations (if any), for the same period to be less than 3.00 to 1.00 as of the end of each fiscal quarter. For purposes of the Leverage Ratio, the Credit Facility provides for the calculation of EBITDA giving pro forma effect to certain acquisitions, divestitures and liquidations during the period to which such calculation relates. As of December 31, 2016, we were in compliance with all financial covenants in our debt agreements.

Total availability under the Credit Facility was $1,524.5 million as of December 31, 2016, which was limited to $803.5 million by the Leverage Ratio in the Credit Facility's credit agreement.

In addition to the Credit Facility, we have various other credit facilities with an aggregate availability of $49.4 million, of which there were no outstanding borrowings at December 31, 2016. Borrowings under these credit facilities bear interest at variable rates.

As of December 31, 2016, we had $122.4 million of cash held in certain countries in which the ability to repatriate is limited due to local regulations or significant potential tax consequences.

We expect to continue to have cash requirements to support working capital needs and capital expenditures, to pay interest and service debt and to pay dividends to shareholders quarterly. We believe we have the ability and sufficient capacity to meet these cash requirements by using available cash and internally generated funds and to borrow under our committed and uncommitted credit facilities.

Further, we plan to utilize a portion of the proceeds from the sale of our Valves & Controls business to retire a significant portion of outstanding debt, and thus reduce our future contractual obligations. We believe the sale of the Valves & Controls business will be completed by the end of the first quarter of 2017, subject to customary regulatory approvals and closing conditions.

Dividends

We paid dividends in 2016 of $243.6 million, or $1.34 per ordinary share, compared with $231.7 million, or $1.28 per ordinary share, in 2015 and $211.4 million, or $1.10 per ordinary share, in 2014.

Under Irish law, the payment of future cash dividends and repurchases of shares may be paid only out of Pentair plc's "distributable reserves" on its statutory balance sheet. Pentair plc is not permitted to pay dividends out of share capital, which includes share premiums. Distributable reserves may be created through the earnings of the Irish parent company and through a reduction in share capital approved by the Irish High Court. Distributable reserves are not linked to a U.S. generally accepted accounting principles ("GAAP") reported amount (e.g., retained earnings). On July 22, 2014, the Irish High Court approved Pentair plc's conversion of approximately $14.4 billion of share premium to distributable reserves. On July 29, 2014, following the approval of the Irish High Court, we made the required filing of Pentair plc's initial accounts with the Irish Companies Registration Office, which completed the process to allow us to pay future cash dividends and redeem and repurchase shares out of Pentair plc's "distributable reserves." Our distributable reserve balance was $9.4 billion and $9.6 billion as of December 31, 2016 and 2015, respectively.

Authorized shares

Our authorized share capital consists of 426.0 million ordinary shares with a par value of $0.01 per share.

Ordinary shares held in treasury

In August 2015, we canceled all of our ordinary shares held in treasury. At the time of the cancellation, we held 19.1 million ordinary shares in treasury at a cost of $1.2 billion.

Share repurchases

Prior to the closing of the Merger, our Board of Directors, and Tyco as our sole shareholder, authorized the repurchase of our ordinary shares with a maximum aggregate value of $400.0 million following the closing of the Merger. In October 2012, the Board of Directors authorized the repurchase of our ordinary shares with a maximum dollar limit of $800.0 million. The authorization expired on December 31, 2015. There is no remaining availability under the 2012 authorizations.

In December 2013, the Board of Directors authorized the repurchase of our ordinary shares up to a maximum dollar limit of $1.0 billion. The authorization expired on December 31, 2016. There is no remaining availability under the 2013 authorization.

In December 2014, the Board of Directors authorized the repurchase of our ordinary shares up to a maximum dollar limit of $1.0 billion. The authorization expires on December 31, 2019.

During the year ended December 31, 2015, we repurchased 3.1 million of our ordinary shares for $200.0 million. We have $800.0 million remaining availability for repurchases under the 2014 authorization.

Contractual obligations

The following summarizes our significant contractual obligations that impact our liquidity:



	Years ended December 31
In millions	2017		2018		2019		2020		2021		Thereafter		Total
Debt obligations	$	0.8	$	500.0	$	2,096.2	$	400.0	$	500.0	$	800.0	$	4,297.0
Interest obligations on fixed-rate debt	107.0		98.1		83.5		64.2		38.3		55.3		446.4
Operating lease obligations, net of sublease rentals	29.8		23.9		19.3		14.4		10.7		12.2		110.3
Purchase and marketing obligations	61.2		19.0		5.0		2.4		2.4		9.5		99.5
Pension and other post-retirement plan contributions	13.5		13.5		14.4		16.1		13.9		71.4		142.8

The majority of the purchase obligations represent commitments for raw materials to be utilized in the normal course of business. For purposes of the above table, arrangements are considered purchase obligations if a contract specifies all significant terms, including fixed or minimum quantities to be purchased, a pricing structure and approximate timing of the transaction.

In addition to the summary of significant contractual obligations, we will incur annual interest expense on outstanding variable rate debt. As of December 31, 2016, variable interest rate debt was $976.3 million at a weighted average interest rate of 2.01%.

The total gross liability for uncertain tax positions at December 31, 2016 was estimated to be $71.1 million. We record penalties and interest related to unrecognized tax benefits in Provision for income taxes and Interest expense, respectively, which is consistent with our past practices. As of December 31, 2016, we had recorded $2.4 million for the possible payment of penalties and $11.0 million related to the possible payment of interest.

Other financial measures

In addition to measuring our cash flow generation or usage based upon operating, investing and financing classifications included in the Consolidated Statements of Cash Flows, we also measure our free cash flow. We have a long-term goal to consistently generate free cash flow that equals or exceeds 100 percent conversion of net income. Free cash flow is a non-GAAP financial measure that we use to assess our cash flow performance. We believe free cash flow is an important measure of operating performance because it provides us and our investors a measurement of cash generated from operations that is available to pay dividends, make acquisitions, repay debt and repurchase shares. In addition, free cash flow is used as a criterion to measure and pay compensation-based incentives. Our measure of free cash flow may not be comparable to similarly titled measures reported by other companies. The following table is a reconciliation of free cash flow:



	Years ended December 31
In millions	2016			2015			2014
Net cash provided by (used for) operating activities of continuing operations	$	702.4		$	597.7		$	676.0
Capital expenditures	(117.8		)	(91.3		)	(83.7		)
Proceeds from sale of property and equipment	24.7			4.6			1.9
Free cash flow from continuing operations	$	609.3		$	511.0		$	594.2
Net cash provided by (used for) operating activities of discontinued operations	159.0			141.6			332.4
Capital expenditures of discontinued operations	(20.4		)	(43.0		)	(45.9		)
Proceeds from sale of property and equipment of discontinued operations	21.9			22.7			11.2
Free cash flow	$	769.8		$	632.3		$	891.9

Off-balance sheet arrangements

At December 31, 2016, we had no off-balance sheet financing arrangements.

COMMITMENTS AND CONTINGENCIES

While we believe that a material impact on our consolidated financial position, results of operations or cash flows from any such future claims or potential claims is unlikely, given the inherent uncertainty of litigation, a remote possibility exists that a future adverse ruling or unfavorable development could result in future charges that could have a material impact. We do and will continue to periodically reexamine our estimates of probable liabilities and any associated expenses and receivables and make appropriate adjustments to such estimates based on experience and developments in litigation. As a result, the current estimates of the potential impact on our consolidated financial position, results of operations and cash flows for the proceedings and claims described in ITEM 8, Note 17 of the Notes to Consolidated Financial Statements could change in the future.

Asbestos matters

actions. In addition, the amount does not include certain claims pending against third parties for which we have been provided an indemnification.

Our estimated liability for asbestos-related claims was $228.3 million and $237.9 million as of December 31, 2016 and 2015, respectively, and was recorded in Non-current liabilities held for sale in the Consolidated Balance Sheets for pending and future claims and related defense costs. Our estimated receivable for insurance recoveries was $108.5 million and $111.0 million at December 31, 2016 and 2015, respectively, and was recorded in Non-current assets held for sale in the Consolidated Balance Sheets.

Environmental matters

We are involved in or have retained responsibility and potential liability for environmental obligations and legal proceedings related to our current business and, including pursuant to certain indemnification obligations, related to certain formerly owned businesses. Our accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. Based upon our experience, current information regarding known contingencies and applicable laws, we have recorded reserves for these environmental matters of $18.3 million and $22.8 million as of December 31, 2016 and 2015, respectively, which relate primarily to the Valves & Controls business classified as held for sale. We do not anticipate these environmental conditions will have a material adverse effect on our financial position, results of operations or cash flows.

Product liability claims

Stand-by letters of credit, bank guarantees and bonds

In certain situations, Tyco guaranteed Flow Control's performance to third parties or provided financial guarantees for financial commitments of Flow Control. In situations where Flow Control and Tyco were unable to obtain a release from these guarantees in connection with the spin-off, we will indemnify Tyco for any losses it suffers as a result of such guarantees.

In disposing of assets or businesses, we often provide representations, warranties and indemnities to cover various risks including unknown damage to the assets, environmental risks involved in the sale of real estate, liability to investigate and remediate environmental contamination at waste disposal sites and manufacturing facilities and unidentified tax liabilities and legal fees related to periods prior to disposition. We do not have the ability to reasonably estimate the potential liability due to the inchoate and unknown nature of these potential liabilities. However, we have no reason to believe that these uncertainties would have a material adverse effect on our financial position, results of operations or cash flows.

In the ordinary course of business, we are required to commit to bonds, letters of credit and bank guarantees that require payments to our customers for any non-performance. The outstanding face value of these instruments fluctuates with the value of our projects in process and in our backlog. In addition, we issue financial stand-by letters of credit primarily to secure our performance to third parties under self-insurance programs.

As of December 31, 2016 and 2015, the outstanding value of bonds, letters of credit and bank guarantees totaled $331.0 million and $402.2 million, respectively, of which $156.6 million and $202.3 million, respectively, relate to the Valves & Controls business classified as held for sale.

NEW ACCOUNTING STANDARDS

See ITEM 8, Note 1 of the Notes to Consolidated Financial Statements, included in this Form 10-K, for information pertaining to recently adopted accounting standards or accounting standards to be adopted in the future.

CRITICAL ACCOUNTING POLICIES

We have adopted various accounting policies to prepare the consolidated financial statements in accordance with GAAP. Our significant accounting policies are more fully described in ITEM 8, Note 1 of the Notes to Consolidated Financial Statements. Certain of our accounting policies require the application of significant judgment by management in selecting the appropriate

assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of uncertainty. These judgments are based on our historical experience, terms of existing contracts, our observance of trends in the industry and information available from other outside sources, as appropriate. We consider an accounting estimate to be critical if:


•	it requires us to make assumptions about matters that were uncertain at the time we were making the estimate; and


•	changes in the estimate or different estimates that we could have selected would have had a material impact on our financial condition or results of operations.

Our critical accounting estimates include the following:

Impairment of goodwill and indefinite-lived intangibles

Goodwill

Goodwill represents the excess of the cost of acquired businesses over the net of the fair value of identifiable tangible net assets and identifiable intangible assets purchased and liabilities assumed.

Goodwill is tested at least annually for impairment and is tested for impairment more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test is performed using a two-step process. In the first step, the fair value of each reporting unit is compared with the carrying amount of the reporting unit, including goodwill. If the estimated fair value is less than the carrying amount of the reporting unit there is an indication that goodwill impairment exists and a second step must be completed in order to determine the amount of the goodwill impairment, if any that should be recorded. In the second step, an impairment loss is recognized for any excess of the carrying amount of the reporting unit's goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation.

The fair value of each reporting unit is determined using a discounted cash flow analysis and market approach. Projecting discounted future cash flows requires us to make significant estimates regarding future revenues and expenses, projected capital expenditures, changes in working capital and the appropriate discount rate. Use of the market approach consists of comparisons to comparable publicly-traded companies that are similar in size and industry. Actual results may differ from those used in our valuations.

In developing our discounted cash flow analysis, assumptions about future revenues and expenses, capital expenditures and changes in working capital are based on our annual operating plan and long-term business plan for each of our reporting units. These plans take into consideration numerous factors including historical experience, anticipated future economic conditions, changes in raw material prices and growth expectations for the industries and end markets we participate in. These assumptions are determined over a six year long-term planning period. The six year growth rates for revenues and operating profits vary for each reporting unit being evaluated. Revenues and operating profit beyond 2022 are projected to grow at a perpetual growth rate of 3.0%.

Discount rate assumptions for each reporting unit take into consideration our assessment of risks inherent in the future cash flows of the respective reporting unit and our weighted-average cost of capital. We utilized a discount rate of 9.0% in determining the discounted cash flows in our fair value analysis.

In estimating fair value using the market approach, we identify a group of comparable publicly-traded companies for each reporting unit that are similar in terms of size and product offering. These groups of comparable companies are used to develop multiples based on total market-based invested capital as a multiple of earnings before interest, taxes, depreciation and amortization ("EBITDA"). We determine our estimated values by applying these comparable EBITDA multiples to the operating results of our reporting units. The ultimate fair value of each reporting unit is determined considering the results of both valuation methods.

We completed step one of our annual goodwill impairment evaluation as of the first day of the fourth quarter of 2016, 2015 and 2014 with each of our reporting units' fair value in excess of its carrying value.

During the latter part of the fourth quarter of 2015, the oil and gas industry continued to deteriorate, leading management to reconsider its estimates for future profitability of the reporting unit and thereby increasing the likelihood that the associated goodwill could be impaired. As such, we concluded that a triggering event occurred during the fourth quarter of 2015 requiring that we test Valves & Controls goodwill for impairment. As a result, we reperformed our step one analysis as of December 31, 2015. Consistent with our annual test, the fair value was estimated using both a discounted cash flow analysis and market approach.

The results of our step one goodwill impairment testing as of December 31, 2015 indicated that the fair value of Valves & Controls was below its carrying value. Accordingly, we performed the step two test and concluded the goodwill of the Valves & Controls business classified as held for sale was impaired. As a result, we recorded a non-cash goodwill impairment charge of $515.2 million for the year ended December 31, 2015. The impairment charge was recorded in Income (loss) from discontinued operations, net of tax in our Consolidated Statements of Operations and Comprehensive Income (Loss).

Identifiable intangible assets

Our primary identifiable intangible assets include: customer relationships, trade names and trademarks, proprietary technology, backlog and patents. Identifiable intangibles with finite lives are amortized and those identifiable intangibles with indefinite lives are not amortized. Identifiable intangible assets that are subject to amortization are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Identifiable intangible assets not subject to amortization are tested for impairment annually or more frequently if events warrant. We complete our annual impairment test during the fourth quarter each year for those identifiable assets not subject to amortization.

The impairment test consists of a comparison of the fair value of the trade name with its carrying value. Fair value is measured using the relief-from-royalty method. This method assumes the trade name has value to the extent that the owner is relieved of the obligation to pay royalties for the benefits received from them. This method requires us to estimate the future revenue for the related brands, the appropriate royalty rate and the weighted average cost of capital.

An impairment charge of $13.3 million was recorded in 2016 related to a trade name in Technical Solutions as the result of a rebranding strategy implemented in the fourth quarter of 2016. The trade name impairment charges were recorded in Selling, general and administrative in our Consolidated Statements of Operations and Comprehensive Income (Loss).

As noted above, during the latter part of the fourth quarter of 2015, the oil and gas industry continued to deteriorate, leading management to reconsider its estimates for future profitability of the Valves & Controls and thereby increasing the likelihood that the associated intangible assets could be impaired. As such, we concluded that a triggering event occurred during the fourth quarter of 2015 requiring that we test Valves & Controls trade names for impairment. As a result of this test, an impairment charge of $39.5 million was recorded in 2015 related to trade names in the Valves & Controls business classified as held for sale. The impairment charge was recorded in Income (loss) from discontinued operations, net of tax in our Consolidated Statements of Operations and Comprehensive Income (Loss).

There were no impairment charges recorded in 2014 for identifiable intangible assets.

Pension and other post-retirement plans

We sponsor U.S. and Non-U.S. defined-benefit pension and other post-retirement plans. The amounts recognized in our consolidated financial statements related to our defined-benefit pension and other post-retirement plans are determined from actuarial valuations. Inherent in these valuations are assumptions, including: expected return on plan assets, discount rates, rate of increase in future compensation levels and health care cost trend rates. These assumptions are updated annually and are disclosed in ITEM 8, Note 13 to the Notes to Consolidated Financial Statements. Differences in actual experience or changes in assumptions may affect our pension and other post-retirement obligations and future expense.

We recognize changes in the fair value of plan assets and net actuarial gains or losses for pension and other post-retirement benefits annually in the fourth quarter each year ("mark-to-market adjustment") and, if applicable, in any quarter in which an interim remeasurement is triggered. Net actuarial gains and losses occur when the actual experience differs from any of the various assumptions used to value our pension and other post-retirement plans or when assumptions change as they may each year. The primary factors contributing to actuarial gains and losses each year are (1) changes in the discount rate used to value pension and other post-retirement benefit obligations as of the measurement date and (2) differences between the expected and the actual return on plan assets. This accounting method also results in the potential for volatile and difficult to forecast mark-to-market adjustments. Mark-to-market adjustments resulted in a pre-tax charge of $4.2 million in 2016, pre-tax income of $23.0 million in 2015 and a pre-tax charge of $31.5 million in 2014. The remaining components of pension expense, including service and interest costs and the expected return on plan assets, are recorded on a quarterly basis as ongoing pension expense.

Discount rate

The discount rate reflects the current rate at which the pension liabilities could be effectively settled at the end of the year based on our December 31 measurement date. The discount rate was determined by matching our expected benefit payments to payments from a stream of bonds available in the marketplace rated AA or higher, adjusted to eliminate the effects of call provisions. This produced a weighted-average discount rate for our U.S. plans of 4.02% in 2016, 4.21% in 2015 and 3.63% in 2014. The discount rates on our Non-U.S. plans ranged from 0.50% to 4.00% in 2016, 0.50% to 4.25% in 2015 and 0.50% to 4.25% in 2014. There are no known or anticipated changes in our discount rate assumption that will impact our pension expense in 2017.

Expected rate of return

Our expected rate of return on plan assets for our U.S. plans was 4.28% for 2016, 3.65% in 2015 and 4.56% in 2014. The expected rate of return on our Non-U.S. plans ranged from 1.00% to 5.50% in 2016, 1.00% to 6.00% in 2015 and 1.00% to 6.00% in 2014. The expected rate of return is designed to be a long-term assumption that may be subject to considerable year-to-year variance from actual returns. In developing the expected long-term rate of return, we considered our historical returns, with consideration given to forecasted economic conditions, our asset allocations, input from external consultants and broader longer-term market indices.

During 2012, we adopted an investment strategy for our U.S. pension plans with a primary objective of preserving the funded status of the U.S. plans. This was achieved through investments in fixed interest instruments with interest rate sensitivity characteristics closely reflecting the interest rate sensitivity of our benefit obligations. The shifting of allocations away from equities to liability hedging fixed income investments, by reinvesting in fixed income instruments as equity investments were redeemed, was completed during 2013. As of December 31, 2016, the U.S. pension plans have an approximately 99 percent allocation to fixed income investments. As a result of the adoption of this investment strategy, we anticipate the expected rate of return on our U.S. funded pension plans will continue to be consistent with the discount rate.

See ITEM 8, Note 13 of the Notes to Consolidated Financial Statements for further information regarding pension and other post-retirement plans.

Loss contingencies

Accruals are recorded for various contingencies including legal proceedings, self-insurance and other claims that arise in the normal course of business. The accruals are based on judgment, the probability of losses and, where applicable, the consideration of opinions of internal and/or external legal counsel and actuarially determined estimates. Additionally, we record receivables from third party insurers when recovery has been determined to be probable.

We recognize asbestos-related liabilities on an undiscounted basis when a loss is probable and can be reasonably estimated. Certain of these liabilities are subject to insurance coverage. Our subsidiaries and numerous other companies are named as defendants in personal injury lawsuits based on alleged exposure to asbestos-containing materials. These cases typically involve product liability claims based primarily on allegations of manufacture, sale or distribution of industrial products that either contained asbestos or were attached to or used with asbestos-containing components manufactured by third-parties. The process of estimating asbestos-related liabilities and the corresponding insurance recoveries receivable is complex and dependent primarily on our historical claim experience, estimates of potential future claims, our legal strategy for resolving these claims, the availability of insurance coverage, and the solvency and creditworthiness of insurers.

See ITEM 8, Note 17 of the Notes to Consolidated Financial Statements for further information regarding loss contingencies.

Income taxes

In determining taxable income for financial statement purposes, we must make certain estimates and judgments. These estimates and judgments affect the calculation of certain tax liabilities and the determination of the recoverability of certain of the deferred tax assets, which arise from temporary differences between the tax and financial statement recognition of revenue and expense. In evaluating our ability to recover our deferred tax assets we consider all available positive and negative evidence including our past operating results, the existence of cumulative losses in the most recent years and our forecast of future taxable income. In estimating future taxable income, we develop assumptions including the amount of future pre-tax operating income, the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage the underlying businesses.

We currently have recorded valuation allowances that we will maintain until when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Our income tax expense recorded in the future may be reduced to the extent of decreases in our valuation allowances. The realization of our remaining deferred tax assets is primarily dependent on future taxable income in the appropriate jurisdiction. Any reduction in future taxable income including but not limited to any future restructuring activities may require that we record an additional valuation allowance against our deferred tax assets. An increase in the valuation allowance could result in additional income tax expense in such period and could have a significant impact on our future earnings.

Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Management records the effect of a tax rate or law change on the Company's deferred tax assets and liabilities in the period of enactment. Future tax rate or law changes could have a material effect on the Company's financial condition, results of operations or cash flows.

In addition, the calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations in a multitude of jurisdictions across our global operations. We perform reviews of our income tax positions on a quarterly basis

and accrue for uncertain tax positions. We recognize potential liabilities and record tax liabilities for anticipated tax audit issues in the tax jurisdictions in which we operate based on our estimate of whether, and the extent to which, additional taxes will be due. These tax liabilities are reflected net of related tax loss carryforwards. As events change or resolution occurs, these liabilities are adjusted, such as in the case of audit settlements with taxing authorities. The ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. If our estimate of tax liabilities proves to be less than the ultimate assessment, an additional charge to expense would result. If payment of these amounts ultimately proves to be less than the recorded amounts, the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the potential economic loss that may result from adverse changes in the fair value of financial instruments. We are exposed to various market risks, including changes in interest rates and foreign currency rates. Periodically, we use derivative financial instruments to manage or reduce the impact of changes in interest rates. Counterparties to all derivative contracts are major financial institutions. All instruments are entered into for other than trading purposes. The major accounting policies and utilization of these instruments is described more fully in ITEM 8, Note 1 of the Notes to Consolidated Financial Statements.

Interest rate risk

Our debt portfolio as of December 31, 2016, was comprised of debt predominantly denominated in U.S. dollars. This debt portfolio is comprised of 77% fixed-rate debt and 23% variable-rate debt. Changes in interest rates have different impacts on the fixed and variable-rate portions of our debt portfolio. A change in interest rates on the fixed portion of the debt portfolio impacts the fair value but has no impact on interest incurred or cash flows. A change in interest rates on the variable portion of the debt portfolio impacts the interest incurred and cash flows but does not impact the net financial instrument position.

Based on the fixed-rate debt included in our debt portfolio, as of December 31, 2016, a 100 basis point increase or decrease in interest rates would result in a $118.5 million decrease or a $124.3 million increase in fair value, respectively.

Based on the variable-rate debt included in our debt portfolio as of December 31, 2016, a 100 basis point increase or decrease in interest rates would result in a $9.8 million increase or decrease in interest incurred.

Foreign currency risk

We conduct business in various locations throughout the world and are subject to market risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. Periodically, we use derivative financial instruments to manage these risks. The functional currencies of our foreign operating locations are generally the local currency in the country of domicile. We manage these operating activities at the local level and revenues, costs, assets and liabilities are generally denominated in local currencies, thereby mitigating the risk associated with changes in foreign exchange. However, our results of operations and assets and liabilities are reported in U.S. dollars and thus will fluctuate with changes in exchange rates between such local currencies and the U.S. dollar.

From time to time, we may enter into short duration foreign currency contracts to hedge foreign currency risks. As the majority of our foreign currency contracts have an original maturity date of less than one year, there is no material foreign currency risk. At December 31, 2016 and 2015, we had outstanding foreign currency derivative contracts with gross notional U.S. dollar equivalent amounts of $475.6 million and $331.5 million, respectively. Changes in the fair value of all derivatives are recognized immediately in income unless the derivative qualifies as a hedge of future cash flows. Gains and losses related to a hedge are deferred and recorded in the Consolidated Balance Sheets as a component of AOCI and subsequently recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss) when the hedged item affects earnings.

In September 2015, we designated the €500.0 million 2.45% Senior Notes due 2019 (the "2019 Euro Notes") as a net investment hedge of our investments in certain international subsidiaries that use the Euro as their functional currency. The hedge is intended to reduce, but will not eliminate, the impact on our financial results of changes in the exchange rate between the Euro and the U.S. dollar. The currency risk related to the net investment hedge is measured by estimating the potential impact of a 10% change in the value of the U.S. dollar relative to the Euro. The rates used to perform this analysis were based on the market exchange rates in effect on December 31, 2016. A 10% appreciation of the U.S. dollar relative to the Euro would result in a $47.3 million net increase in Other comprehensive income. Conversely, a 10% depreciation of the U.S. dollar relative to the Euro would result in a $57.9 million net decrease in Other comprehensive income. However, these increases and decreases in Other comprehensive income would be offset by decreases or increases in the hedged net investments on our balance sheet due to currency translation.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of Pentair plc and its subsidiaries (the "Company") is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934. The Company's internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company's internal control over financial reporting includes those policies and procedures that (1) pertain to maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of the financial statements in accordance with generally accepted accounting principles and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of the effectiveness of internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2016. In making this assessment, management used the criteria for effective internal control over financial reporting described in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management believes that, as of December 31, 2016, the Company's internal control over financial reporting was effective based on those criteria.

Our independent registered public accounting firm, Deloitte & Touche LLP, has issued an attestation report on the Company's internal control over financial reporting as of December 31, 2016. That attestation report is set forth immediately following this management report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Pentair plc

London, United Kingdom

We have audited the internal control over financial reporting of Pentair plc and subsidiaries (the "Company") as of December 31, 2016, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule listed in the Index at Item 15 as of and for the year ended December 31, 2016 of the Company and our report dated February 21, 2017 expressed an unqualified opinion on those financial statements and financial statement schedule.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Pentair plc

London, United Kingdom

We have audited the accompanying consolidated balance sheets of Pentair plc and subsidiaries (the "Company") as of December 31, 2016 and 2015, and the related consolidated statements of operations and comprehensive income (loss), changes in equity, and cash flows for each of the three years in the period ended December 31, 2016. Our audits also included the consolidated financial statement schedule listed in the Index at Item 15. These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Pentair plc and subsidiaries as of December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2016, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such consolidated financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2016, based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 21, 2017 expressed an unqualified opinion on the Company's internal control over financial reporting.

Notes to consolidated financial statements


1.	Basis of Presentation and Summary of Significant Accounting Policies

Business

Pentair plc and its consolidated subsidiaries (the "Company" or "Pentair") is a focused diversified industrial manufacturing company comprising three reporting segments: Water Quality Systems, Flow & Filtration Solutions and Technical Solutions.

In December 2013, the Company's Board of Directors approved changing the Company's jurisdiction of organization from Switzerland to Ireland. At an extraordinary meeting of shareholders on May 20, 2014, Pentair Ltd. shareholders voted in favor of a reorganization proposal pursuant to which Pentair Ltd. would merge into Pentair plc, an Irish company, and all Pentair Ltd. CHF 0.50 par value common shares would be canceled and all holders of such shares would receive $0.01 par value ordinary shares of Pentair plc on a one-for-one basis. The reorganization transaction was completed on June 3, 2014, at which time Pentair plc replaced Pentair Ltd. as our ultimate parent company (the "Redomicile"). Shares of Pentair plc began trading on the New York Stock Exchange on June 3, 2014 under the symbol "PNR," the same symbol under which Pentair Ltd. shares were previously traded. Although our jurisdiction of organization is Ireland, we manage our affairs so that we are centrally managed and controlled in the United Kingdom (the "U.K.") and therefore have our tax residency in the U.K.

Basis of presentation

The accompanying consolidated financial statements include the accounts of Pentair and all subsidiaries, both the United States ("U.S.") and non-U.S., which we control. Intercompany accounts and transactions have been eliminated. Investments in companies of which we own 20% to 50% of the voting stock or have the ability to exercise significant influence over operating and financial policies of the investee are accounted for using the equity method of accounting and as a result, our share of the earnings or losses of such equity affiliates is included in the Consolidated Statements of Operations and Comprehensive Income (Loss).

The consolidated financial statements have been prepared in U.S. dollars ("USD") and in accordance with accounting principles generally accepted in the United States of America ("GAAP").

Fiscal year

Our fiscal year ends on December 31. Beginning in the first quarter of 2016, we report our interim quarterly periods on a calendar quarter basis. Prior to the first quarter of 2016, we reported our interim quarterly periods on a 13-week basis ending on a Saturday.

Use of estimates

The preparation of our consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes, disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates include our accounting for valuation of goodwill and indefinite lived intangible assets, estimated losses on accounts receivable, estimated realizable value on excess and obsolete inventory, percentage of completion revenue recognition, assets acquired and liabilities assumed in acquisitions, estimated selling proceeds from assets held for sale, contingent liabilities, income taxes and pension and other post-retirement benefits. Actual results could differ from our estimates.

Revenue recognition

We recognize revenue when it is realized or realizable and has been earned. Revenue is recognized when persuasive evidence of an arrangement exists, shipment or delivery has occurred (depending on the terms of the sale), our price to the buyer is fixed or determinable, and collectability is reasonably assured.

Generally, there is no post-shipment obligation on product sold other than warranty obligations in the normal and ordinary course of business. In the event significant post-shipment obligations were to exist, revenue recognition would be deferred until substantially all obligations were satisfied.

Pentair plc and Subsidiaries

Notes to consolidated financial statements

Percentage of completion

Revenue from certain long-term contracts is recognized over the contractual period under the percentage of completion method of accounting. Under this method, sales and gross profit are recognized as work is performed either based on the relationship between the actual costs incurred and the total estimated costs at completion ("the cost-to-cost method") or based on efforts for measuring progress towards completion in situations in which this approach is more representative of the progress on the contract than the cost-to-cost method. Changes to the original estimates may be required during the life of the contract and such estimates are reviewed on a regular basis. Sales and gross profit are adjusted using the cumulative catch-up method for revisions in estimated total contract costs. These reviews have not resulted in adjustments that were significant to our results of operations. Estimated losses are recorded when identified. Claims against customers are recognized as revenue upon settlement.

We record costs and earnings in excess of billings on uncompleted contracts within Other current assets and billings in excess of costs and earnings on uncompleted contracts within Other current liabilities in the Consolidated Balance Sheets.

Sales returns

The right of return may exist explicitly or implicitly with our customers. Generally, our return policy allows for customer returns only upon our authorization. Goods returned must be product we continue to market and must be in salable condition. Returns of custom or modified goods are normally not allowed. At the time of sale, we reduce revenue for the estimated effect of returns. Estimated sales returns include consideration of historical sales levels, the timing and magnitude of historical sales return levels as a percent of sales, type of product, type of customer and a projection of this experience into the future.

Pricing and sales incentives

We record estimated reductions to revenue for customer programs and incentive offerings including pricing arrangements, promotions and other volume-based incentives at the later of the date revenue is recognized or the incentive is offered. Sales incentives given to our customers are recorded as a reduction of revenue unless we (1) receive an identifiable benefit for the goods or services in exchange for the consideration and (2) we can reasonably estimate the fair value of the benefit received.

Pricing is established at or prior to the time of sale with our customers and we record sales at the agreed-upon net selling price. However, one of our businesses allows customers to apply for a refund of a percentage of the original purchase price if they can demonstrate sales to a qualifying end customer. At the time of sale, we estimate the anticipated refund to be paid based on historical experience and reduce sales for the probable cost of the discount. The cost of these refunds is recorded as a reduction in gross sales.

Volume-based incentives involve rebates that are negotiated at or prior to the time of sale with the customer and are redeemable only if the customer achieves a specified cumulative level of sales or sales increase. Under these incentive programs, at the time of sale, we reforecast the anticipated rebate to be paid based on forecasted sales levels. These forecasts are updated at least quarterly for each customer and sales are reduced for the anticipated cost of the rebate. If the forecasted sales for a customer changes, the accrual for rebates is adjusted to reflect the new amount of rebates expected to be earned by the customer.

Shipping and handling costs

Amounts billed to customers for shipping and handling are recorded in Net sales in the accompanying Consolidated Statements of Operations and Comprehensive Income (Loss). Shipping and handling costs incurred by Pentair for the delivery of goods to customers are included in Cost of goods sold in the accompanying Consolidated Statements of Operations and Comprehensive Income (Loss).

Research and development

We conduct research and development ("R&D") activities in our own facilities, which consist primarily of the development of new products, product applications and manufacturing processes. We expense R&D costs as incurred. R&D expenditures during 2016, 2015 and 2014 were $114.1 million, $98.7 million and $96.4 million, respectively.

Cash equivalents

We consider highly liquid investments with original maturities of three months or less at the date of acquisition to be cash equivalents.

Trade receivables and concentration of credit risk

We record an allowance for doubtful accounts, reducing our receivables balance to an amount we estimate is collectible from our customers. Estimates used in determining the allowance for doubtful accounts are based on current trends, aging of accounts receivable, periodic credit evaluations of our customers' financial condition, and historical collection experience. We generally do not require collateral. No customer receivable balances exceeded 10% of total net receivable balances as of December 31, 2016 or December 31, 2015.

Notes to consolidated financial statements

Inventories

Inventories are stated at the lower of cost or market with substantially all inventories recorded using the first-in, first-out ("FIFO") cost method and with an insignificant amount of inventories located outside the U.S. recorded using a moving average cost method which approximates FIFO.

Property, plant and equipment, net

Property, plant and equipment is stated at historical cost. We compute depreciation by the straight-line method based on the following estimated useful lives:



	Years
Land improvements	5 to 20
Buildings and leasehold improvements	5 to 50
Machinery and equipment	3 to 15

Significant improvements that add to productive capacity or extend the lives of properties are capitalized. Costs for repairs and maintenance are charged to expense as incurred. When property is retired or otherwise disposed of, the recorded cost of the assets and their related accumulated depreciation are removed from the Consolidated Balance Sheets and any related gains or losses are included in income.

We review the recoverability of long-lived assets to be held and used, such as property, plant and equipment, when events or changes in circumstances occur that indicate the carrying value of the asset or asset group may not be recoverable. The assessment of possible impairment is based on our ability to recover the carrying value of the asset or asset group from the expected future pre-tax cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset or asset group, an impairment loss is recognized for the difference between estimated fair value and carrying value. Impairment losses on long-lived assets held for sale are determined in a similar manner, except that fair values are reduced for the cost to dispose of the assets. The measurement of impairment requires us to estimate future cash flows and the fair value of long-lived assets. We recorded no impairment charges in 2016 in conjunction with restructuring activities. During 2015 and 2014, we recorded $5.1 million and $13.0 million, respectively, in conjunction with restructuring activities.

Goodwill and identifiable intangible assets

Goodwill

Goodwill is tested annually for impairment and is tested for impairment more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test is performed using a two-step process. In the first step, the fair value of each reporting unit is compared with the carrying amount of the reporting unit, including goodwill. If the estimated fair value is less than the carrying amount of the reporting unit there is an indication that goodwill impairment exists and a second step must be completed in order to determine the amount of the goodwill impairment, if any, that should be recorded. In the second step, an impairment loss is recognized for any excess of the carrying amount of the reporting unit's goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation.

In developing our discounted cash flow analysis, assumptions about future revenues and expenses, capital expenditures and changes in working capital, are based on our annual operating plan and long-term business plan for each of our reporting units. These plans take into consideration numerous factors including historical experience, anticipated future economic conditions, changes in raw material prices and growth expectations for the industries and end markets we participate in. These assumptions are determined over a six year long-term planning period. The six year growth rates for revenues and operating profits vary for each reporting unit being evaluated. Revenues and operating profit beyond 2022 are projected to grow at a perpetual growth rate of 3.0%.

Notes to consolidated financial statements

We completed step one of our annual goodwill impairment evaluation as of the first day of the fourth quarter of 2016, 2015 and 2014 with each reporting unit's fair value in excess of its carrying value.

During the latter part of the fourth quarter of 2015, the oil and gas industry continued to deteriorate, leading management to reconsider its estimates for future profitability of the Valves & Controls reporting unit and thereby increasing the likelihood that the associated goodwill could be impaired. As such, we concluded that a triggering event occurred during the fourth quarter of 2015 requiring that we test Valves & Controls goodwill for impairment. As a result, we reperformed our step one analysis as of December 31, 2015. Consistent with our annual test, the fair value was estimated using both a discounted cash flow analysis and market approach.

The results of our step one goodwill impairment testing as of December 31, 2015 indicated that the fair value of Valves & Controls was below its carrying value. Accordingly, we performed the step two test and concluded the goodwill of Valves & Controls was impaired. As a result, we recorded a non-cash goodwill impairment charge of $515.2 million for the year ended December 31, 2015. The impairment is included in Income (loss) from discontinued operations, net of tax in our Consolidated Statements of Operations and Comprehensive Income (Loss).

Identifiable intangible assets

Our primary identifiable intangible assets include: customer relationships, trade names, proprietary technology and patents. Identifiable intangibles with finite lives are amortized and those identifiable intangibles with indefinite lives are not amortized. Identifiable intangible assets that are subject to amortization are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Identifiable intangible assets not subject to amortization are tested for impairment annually or more frequently if events warrant. We complete our annual impairment test during the fourth quarter each year for those identifiable assets not subject to amortization.

The impairment test for trade names consists of a comparison of the fair value of the trade name with its carrying value. Fair value is measured using the relief-from-royalty method. This method assumes the trade name has value to the extent that the owner is relieved of the obligation to pay royalties for the benefits received from them. This method requires us to estimate the future revenue for the related brands, the appropriate royalty rate and the weighted average cost of capital. The non-recurring fair value measurement is a "Level 3" measurement under the fair value hierarchy described below.

An impairment charge of $13.3 million was recorded in 2016 related to a trade name in Technical Solutions as a result of a rebranding strategy implemented in the fourth quarter of 2016. The trade name impairment charges were recorded in Selling, general and administrative in our Consolidated Statements of Operations and Comprehensive Income (Loss).

As noted above, during the latter part of the fourth quarter of 2015, the oil and gas industry continued to deteriorate, leading management to reconsider its estimates for future profitability of the Valves & Controls and thereby increasing the likelihood that the associated intangible assets could be impaired. As such, we concluded that a triggering event occurred during the fourth quarter of 2015 requiring that we test Valves & Controls trade names for impairment. As a result of this test, an impairment charge of $39.5 million was recorded in 2015 related to trade names in the Valves & Controls business classified as held for sale. The impairment is included in Income (loss) from discontinued operations, net of tax in our Consolidated Statements of Operations and Comprehensive Income (Loss).

There were no impairment charges recorded in 2014 for identifiable intangible assets.

Income taxes

We use the asset and liability approach to account for income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period when the change is

Pentair plc and Subsidiaries

Notes to consolidated financial statements

enacted. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Changes in valuation allowances from period to period are included in our tax provision in the period of change. We recognize the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

Pension and other post-retirement plans

We sponsor U.S. and Non-U.S. defined-benefit pension and other post-retirement plans. The pension and other post-retirement benefit costs for company-sponsored benefit plans are determined from actuarial assumptions and methodologies, including discount rates, expected returns on plan assets and health care cost trend rates. These assumptions are updated annually and are disclosed in Note 13.

Environmental

We recognize environmental clean-up liabilities on an undiscounted basis when a loss is probable and can be reasonably estimated. Such liabilities generally are not subject to insurance coverage. The cost of each environmental clean-up is estimated by engineering, financial and legal specialists based on current law. Such estimates are based primarily upon the estimated cost of investigation and remediation required and the likelihood that, where applicable, other potentially responsible parties ("PRPs") will be able to fulfill their commitments at the sites where Pentair may be jointly and severally liable. The process of estimating environmental clean-up liabilities is complex and dependent primarily on the nature and extent of historical information and physical data relating to a contaminated site, the complexity of the site, the uncertainty as to what remedy and technology will be required and the outcome of discussions with regulatory agencies and other PRPs at multi-party sites. In future periods, new laws or regulations, advances in clean-up technologies and additional information about the ultimate clean-up remedy that is used could significantly change our estimates. Accruals for environmental liabilities are primarily included in Other current liabilities held for sale and Other non-current liabilities held for sale in the Consolidated Balance Sheets.

Asbestos matters

We recognize asbestos-related liabilities on an undiscounted basis when a loss is probable and can be reasonably estimated. Certain of these liabilities are subject to insurance coverage and we recognize receivables for asbestos-related insurance recoveries only when realization of the claim is deemed probable. Our subsidiaries and numerous other companies are named as defendants in personal injury lawsuits based on alleged exposure to asbestos-containing materials. These cases typically involve product liability claims based primarily on allegations of manufacture, sale or distribution of industrial products that either contained asbestos or were attached to or used with asbestos-containing components manufactured by third-parties. The process of estimating asbestos-related liabilities and the corresponding insurance recoveries receivable is complex and dependent primarily on our historical claim experience, estimates of potential future claims, our legal strategy for resolving these claims, the availability of insurance coverage, and the solvency and creditworthiness of insurers. On an annual basis, we review, and update as appropriate, such estimated asbestos liabilities and assets and the underlying assumptions. Accruals for asbestos-related liabilities are included in Other non-current liabilities held for sale and the estimated receivable for insurance recoveries are recorded in Other non-current assets held for sale in the Consolidated Balance Sheets.

Insurance subsidiary

We insure certain general and product liability, property, workers' compensation and automobile liability risks through our regulated wholly-owned captive insurance subsidiary, Penwald Insurance Company ("Penwald"). Reserves for policy claims are established based on actuarial projections of ultimate losses. As of December 31, 2016 and 2015, reserves for policy claims were $63.0 million ($13.2 million included in Other current liabilities and $49.8 million included in Other non-current liabilities) and $62.2 million ($13.2 million included in Other current liabilities and $49.0 million included in Other non-current liabilities), respectively.

Share-based compensation

We account for share-based compensation awards on a fair value basis. The estimated grant date fair value of each option award is recognized in income on an accelerated basis over the requisite service period (generally the vesting period). The estimated fair value of each option award is calculated using the Black-Scholes option-pricing model. From time to time, we have elected to modify the terms of the original grant. These modified grants are accounted for as a new award and measured

Pentair plc and Subsidiaries

Notes to consolidated financial statements

using the fair value method, resulting in the inclusion of additional compensation expense in our Consolidated Statements of Operations and Comprehensive Income (Loss). Restricted share awards and units are recorded as compensation cost on an accelerated basis over the requisite service periods based on the market value on the date of grant.

Performance share units ("PSU") are stock awards where the ultimate number of shares issued will be contingent on the Company's performance against certain financial performance targets. The fair value of each PSU is based on the market value on the date of grant. We recognize expense related to the estimated vesting of our PSUs granted. The estimated vesting of the performance share units is based on the probability of achieving certain financial performance thresholds over the specified performance period.

Earnings (loss) per ordinary share

Basic earnings (loss) per share are computed by dividing net income (loss) attributable to Pentair plc by the weighted-average number of ordinary shares outstanding. Diluted earnings (loss) per share are computed by dividing net income (loss) attributable to Pentair plc by the weighted-average number of ordinary shares outstanding including the dilutive effects of ordinary share equivalents.

Derivative financial instruments

We recognize all derivatives, including those embedded in other contracts, as either assets or liabilities at fair value in our Consolidated Balance Sheets. If the derivative is designated and is effective as a cash-flow hedge, changes in the fair value of the derivative are recorded in Accumulated other comprehensive income (loss) ("AOCI") as a separate component of equity in the Consolidated Balance Sheets and is recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss) when the hedged item affects earnings. If the underlying hedged transaction ceases to exist or if the hedge becomes ineffective, all changes in fair value of the related derivatives that have not been settled are recognized in current earnings. For a derivative that is not designated as or does not qualify as a hedge, changes in fair value are reported in earnings immediately.

Gains and losses on net investment hedges are included in AOCI as a separate component of equity in the Consolidated Balance Sheets.

We use derivative instruments for the purpose of hedging interest rate and currency exposures, which exist as part of ongoing business operations. We do not hold or issue derivative financial instruments for trading or speculative purposes. All other contracts that contain provisions meeting the definition of a derivative also meet the requirements of and have been designated as, normal purchases or sales. Our policy is not to enter into contracts with terms that cannot be designated as normal purchases or sales. From time to time, we may enter into short duration foreign currency contracts to hedge foreign currency risks.

Fair value measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date:

Level 1: Valuation is based on observable inputs such as quoted market prices (unadjusted) for identical assets or liabilities in active markets.

Level 2: Valuation is based on inputs such as quoted market prices for similar assets or liabilities in active markets or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3: Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

In making fair value measurements, observable market data must be used when available. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.

Foreign currency translation

The financial statements of subsidiaries located outside of the U.S. are generally measured using the local currency as the functional currency, except for certain corporate entities outside of the U.S. which are measured using USD. Assets and liabilities of these subsidiaries are translated at the rates of exchange at the balance sheet date. Income and expense items are translated at average monthly rates of exchange. The resultant translation adjustments are included in AOCI, a separate component of equity.

New accounting standards

In March 2016, the Financial Accounting Standards Board ("FASB") issued a new accounting standard that will change certain aspects of accounting for share-based payments to employees, including the accounting for income taxes, forfeitures and statutory withholding requirements, as well as classification in the statement of cash flows. The new standard is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. We will adopt this standard during the first quarter of 2017. We do not expect the adoption of the standard to have a significant impact on our financial condition or results of operations.

In February 2016, the FASB issued new accounting requirements regarding accounting for leases, which require an entity to recognize both assets and liabilities arising from financing and operating leases, along with additional qualitative and quantitative disclosures. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within that reporting period, and early adoption is permitted. We have not yet determined the potential effects on our financial condition or results of operations.

In November 2015, the FASB issued a new accounting standard which clarifies and simplifies the balance sheet classification of deferred tax assets and liabilities. Under the new standard, all deferred tax assets and liabilities are required to be classified as non-current in a classified balance sheet. The Company adopted the new standard on a prospective basis in the fourth quarter of 2016 and the prior period was not retrospectively adjusted. The adoption of the standard did not impact the Company's consolidated financial position, results of operations, equity or cash flows.

In April 2015, the FASB issued a new accounting standard which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. The new standard was effective for annual and interim periods beginning after December 15, 2015. We adopted the new standard during the first quarter of 2016 and, as a result, reclassified unamortized debt issuance costs of $23.5 million from Other current assets and Other non-current assets to Long-term debt on the Consolidated Balance Sheet as of December 31, 2015.

In May 2014, the FASB issued new accounting requirements for the recognition of revenue from contracts with customers. The new requirements also include additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The requirements are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The Company intends to adopt the new revenue guidance as of January 1, 2018 and is currently evaluating the overall impact this standard will have on our consolidated financial statements and related disclosures, as well as the expected method of adoption.


2.	Acquisitions

Material acquisitions

The purchase price has been allocated based on the fair value of assets acquired and liabilities assumed at the date of the ERICO Acquisition. The purchase price allocation was completed in the third quarter of 2016.

The following table summarizes our preliminary estimates of the fair values of the assets acquired and liabilities assumed in the ERICO Acquisition as previously reported at December 31, 2015 and as revised for adjustments made during 2016:

In millions	As Originally Reported			As Revised
Cash	$	11.8		$	11.8
Accounts receivable	75.9			75.9
Inventories	102.4			101.8
Other current assets	2.9			2.8
Property, plant and equipment	53.4			53.1
Identifiable intangible assets	1,033.8			1,033.8

Other liabilities	(8.0		)	(15.1		)
Purchase price	$	1,818.1		$	1,818.1

The excess of purchase price over tangible net assets and identified intangible assets acquired has been allocated to goodwill in the amount of $1,031.0 million, none of which is expected to be deductible for income tax purposes. Identifiable intangible assets acquired as part of the ERICO Acquisition include $228.4 million of indefinite-lived trade name intangible assets and $805.4 million of definite-lived customer relationships with an estimated useful life of 21 years.

The following unaudited pro forma consolidated condensed financial results of operations are presented as if the ERICO Acquisition was consummated on January 1, 2014, the beginning of the comparable prior annual reporting period:



	Years ended December 31
In millions, except share and per-share data	2015		2014
Pro forma net sales	$	5,002.6	$	5,223.8
Pro forma net income from continuing operations	460.4		358.8
Pro forma earnings per ordinary share - continuing operations
Basic	$	2.55	$	1.88
Diluted	2.52		1.85

The unaudited pro forma net income from continuing operations for the year ended December 31, 2014 was adjusted to include the impact of $32.8 million in non-recurring items related to acquisition date fair value adjustments to inventory. The unaudited pro forma net income for the year ended December 31, 2015 excludes the impact of $24.6 million of non-recurring transaction related and bridge financing costs.

The pro forma condensed consolidated financial information has been prepared for comparative purposes only and includes certain adjustments, as noted above. The adjustments are estimates based on currently available information and actual amounts may differ materially from these estimates. They do not reflect the effect of costs or synergies that would have been expected to result from the integration of the ERICO Acquisition. The pro forma information does not purport to be indicative of the results of operations that actually would have resulted had the ERICO Acquisition occurred on January 1, 2014.

Other acquisitions

In November 2016, we completed an acquisition as part of Water Quality Systems with a purchase price of $25.0 million in cash, net of cash acquired. The pro forma impact of the acquisition was not material.

In April 2015, we acquired, as part of Technical Solutions, all of the outstanding shares of capital stock of Nuheat Industries Limited ("Nuheat") for $96.0 million in cash (120.5 million Canadian dollars translated at the April 2, 2015 exchange rate), net of cash acquired. In November 2015, cash of $0.9 million (1.2 million Canadian dollars translated at the average monthly exchange rate) was paid to Nuheat in settlement of a working capital adjustment. Based in Canada, Nuheat is a leading manufacturer of electric floor heating systems that are distributed across North America. Total goodwill recorded as part of the purchase allocation was $43.2 million, none of which is tax deductible. Identified intangible assets acquired consisted of customer relationships of $53.3 million, with an estimated useful life of 17 years. The pro forma impact of this acquisition was not material.

3.	Discontinued Operations

On August 18, 2016, we entered into a Share Purchase Agreement (the "Purchase Agreement") to sell our Valves & Controls business to Emerson Electric Co. for a purchase price of $3.15 billion in cash, subject to certain customary adjustments. We believe the sale will be completed by the end of the first quarter of 2017, subject to customary regulatory approvals and closing conditions.

We have concluded, as a result of the signing of the Purchase Agreement, that the Valves & Controls business has met the criteria to be classified as held for sale. The results of the Valves & Controls business have been presented as discontinued operations and the related assets and liabilities have been reclassified as held for sale for all periods presented. The Valves & Controls business was previously disclosed as a stand-alone reporting segment. Transaction costs of $24.2 million related to the sale of Valves & Controls were incurred during the year ended December 31, 2016 and were recorded within Selling, general and administrative expenses in the operating results of discontinued operations presented below.

On July 28, 2014, our Board of Directors approved a decision to exit our Water Transport business in Australia. During the third quarter of 2014, we recognized an impairment charge related to allocated amounts of goodwill, intangible assets, property, plant & equipment and other non-current assets totaling $380.1 million, net of a $12.3 million tax benefit, representing our estimated loss on disposal of the Water Transport business. The impairment charge was determined using significant unobservable inputs ("Level 3" fair value measurements). In addition, during the first quarter of 2014 and fourth quarter of 2013, we sold portions of our Water Transport business in Australia and New Zealand, respectively, resulting in losses of $5.6 million, net of a $2.4 million tax benefit, and $0.8 million, net of a $0.3 million tax benefit, respectively.

During 2015, we sold the remainder of our Water Transport business and received cash proceeds of $59.0 million. The results of the Water Transport business have been presented as discontinued operations.

Operating results of discontinued operations are summarized below:

maximum aggregate availability to $2,100.0 million and a maturity date of October 3, 2019. Borrowings under the Credit Facility generally bear interest at a variable rate equal to the London Interbank Offered Rate ("LIBOR") plus a specified margin based upon PFSA's credit ratings. PFSA must pay a facility fee ranging from 9.0 to 25.0 basis points per annum (based upon PFSA's credit ratings) on the amount of each lender's commitment and letter of credit fee for each letter of credit issued and outstanding under the Credit Facility.

PFSA is authorized to sell short-term commercial paper notes to the extent availability exists under the Credit Facility. PFSA uses the Credit Facility as back-up liquidity to support 100% of commercial paper outstanding. As of December 31, 2016 and 2015, we had $398.7 million and $179.5 million, respectively, of commercial paper outstanding, all of which was classified as long-term as we have the intent and the ability to refinance such obligations on a long-term basis under the Credit Facility.

Total availability under the Credit Facility was $1,524.5 million as of December 31, 2016, which was limited to $803.5 million by the Leverage Ratio in the Credit Facility's credit agreement.

We have $350.0 million of fixed rate senior notes maturing in September 2017. We classified this debt as long-term as of December 31, 2016 as we have the intent and ability to refinance such obligation on a long-term basis under the Credit Facility.

11.	Derivatives and Financial Instruments

Derivative financial instruments

We are exposed to market risk related to changes in foreign currency exchange rates. To manage the volatility related to this exposure, we periodically enter into a variety of derivative financial instruments. Our objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign currency rates. The derivative contracts contain credit risk to the extent that our bank counterparties may be unable to meet the terms of the agreements. The amount of such credit risk is generally limited to the unrealized gains, if any, in such contracts. Such risk is minimized by limiting those counterparties to major financial institutions of high credit quality.

Foreign currency contracts

We conduct business in various locations throughout the world and are subject to market risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. We manage our economic and transaction exposure to certain market-based risks through the use of foreign currency derivative financial instruments. Our objective in holding these derivatives is to reduce the volatility of net earnings and cash flows associated with changes in foreign currency exchange rates. The majority of our foreign currency contracts have an original maturity date of less than one year.

At December 31, 2016 and 2015, we had outstanding foreign currency derivative contracts with gross notional U.S. dollar equivalent amounts of $475.6 million and $331.5 million, respectively. The impact of these contracts on the Consolidated Statements of Operations and Comprehensive Income (Loss) was not material for any period presented.

Gains or losses on foreign currency contracts designated as hedges are reclassified out of AOCI and into Selling, general and administrative expense in the Consolidated Statements of Operations and Comprehensive Income (Loss) upon settlement. Such reclassifications during 2016, 2015 and 2014 were not material.

Net investment hedge

We have net investments in foreign subsidiaries that are subject to changes in the foreign currency exchange rate. In September 2015, we designated the €500 million 2.45% Senior Notes due 2019 (the "2019 Euro Notes") as a net investment hedge for a portion of our net investment in our Euro denominated subsidiaries. The gains/losses on the 2019 Euro Notes have been included as a component of the cumulative translation adjustment account within AOCI. As of December 31, 2016 and 2015, we had deferred foreign currency gains of $44.2 million and $16.4 million, respectively, in AOCI associated with the net investment hedge activity.

Fair value of financial instruments

The following methods were used to estimate the fair values of each class of financial instrument:


•	short-term financial instruments (cash and cash equivalents, accounts and notes receivable, accounts and notes payable and variable-rate debt) — recorded amount approximates fair value because of the short maturity period;


•	long-term fixed-rate debt, including current maturities — fair value is based on market quotes available for issuance of debt with similar terms, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance; and


•	foreign currency contract agreements — fair values are determined through the use of models that consider various assumptions, including time value, yield curves, as well as other relevant economic measures, which are inputs that are classified as Level 2 in the valuation hierarchy defined by the accounting guidance.

The recorded amounts and estimated fair values of total debt, excluding unamortized issuance costs and discounts, at December 31 were as follows:



	2016				2015
In millions	Recorded Amount		Fair Value		Recorded Amount		Fair Value
Variable rate debt	$	976.3	$	976.3	$	1,360.9	$	1,360.9

(1)

During the fourth quarter of 2016, we completed our annual intangible assets impairment review. As a result, we recorded a pre-tax non-cash impairment charge of $13.3 million for a trade name intangible in 2016. The impairment charge reduced the carrying value of the impacted trade name intangible to $0. The fair value of trade names is measured using the relief-from-royalty method. This method assumes the trade name has value to the extent that the owner is relieved of the obligation to pay royalties for the benefits received from them. This method requires us to estimate the future revenue for the related brands, the appropriate royalty rate and the weighted average cost of capital.

(2)

Deferred compensation plan assets include mutual funds, common/collective trusts and cash equivalents for payment of certain non-qualified benefits for retired, terminated and active employees. The fair value of mutual funds and cash equivalents were based on quoted market prices in active markets. The underlying investments in the common/collective trusts primarily include intermediate and long-term debt securities, corporate debt securities, equity securities and fixed income securities. The overall fair value of the common/collective trusts are based on observable inputs.

(3)

During the fourth quarter of 2015, we performed a goodwill impairment test for the Valves & Controls reporting unit using the required two-step process as of December 31, 2015. As a result, we recorded a non-cash goodwill impairment charge of $515.2 million. The first step of this process includes comparing the fair value to the carrying value of the reporting unit to which the goodwill is allocated to identify potential impairment. If the fair value of the reporting unit exceeds its carrying value, goodwill allocated to that reporting unit is not considered impaired. If the inverse result is observed, the reporting unit is considered to be impaired and step two of the test to measure the amount of impairment must be completed.

The fair value of the reporting unit was determined using a discounted cash flow analysis and market approach. Projecting discounted future cash flows requires us to make significant estimates regarding future revenues and expenses, projected capital expenditures, changes in working capital and the appropriate discount rate. Use of the market approach consists of comparisons to comparable publicly-traded companies that are similar in size and industry. Actual results may differ from those used in our valuations.

Step two compares the implied fair value of the goodwill with the carrying value of that goodwill. If the carrying value of the goodwill exceeds its implied fair value, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination.

During the fourth quarter of 2015, we performed an impairment test for our Valves & Controls trade names. As a result, we recorded a pre-tax, non-cash trade name impairment charge of $39.5 million. The fair value of trade names is measured using the relief-from-royalty method. This method assumes the trade name has value to the extent that the owner is relieved of the obligation to pay royalties for the benefits received from them. This method requires us to estimate the future revenue for the related brands, the appropriate royalty rate and the weighted average cost of capital.

The Valves & Controls business referred to above has met the criteria to be classified as held for sale and is presented as discontinued operations for all periods presented. See Note 3 of the Notes to the Consolidated Financial Statements for additional information.

Reconciliations of the beginning and ending gross unrecognized tax benefits were as follows:



	Years ended December 31
In millions	2016			2015			2014

Gross increases due to acquisitions	5.3			6.6			—
Ending balance	$	71.1		$	45.6		$	40.3

Included in the $71.1 million of total gross unrecognized tax benefits as of December 31, 2016 was $68.3 million of tax benefits that, if recognized, would impact the effective tax rate. It is reasonably possible that the gross unrecognized tax benefits as of December 31, 2016 may decrease by a range of zero to $42.2 million during 2017, primarily as a result of the resolution of non-U.K. examinations, including U.S. federal and state examinations, and the expiration of various statutes of limitations. The $27.4 million gross increase for tax positions in prior periods consists primarily of a tentative settlement with the Internal Revenue Service ("IRS") related to the value of certain intellectual property sold from the U.S. to a non-U.S. affiliate. The increase for tax positions in prior periods had no impact on our effective tax rate.

Based on the outcome of these examinations, or as a result of the expiration of statute of limitations for specific jurisdictions, it is reasonably possible that certain unrecognized tax benefits for tax positions taken on previously filed tax returns will materially change from those recorded as liabilities in our financial statements. The IRS is currently examining the Panthro Acquisition Co. U.S. federal income tax returns for tax years ending December 31, 2012 and December 31, 2013. A number of tax periods from 2002 to present are under audit by tax authorities in various jurisdictions, including Canada, France, Germany, India, Italy, New Zealand and Singapore. We anticipate that several of these audits may be concluded in the foreseeable future. We are also subject to the 2012 Tax Sharing Agreement, discussed below, which generally applies to pre-Distribution Tyco tax periods which remain subject to audit by the IRS.

We record penalties and interest related to unrecognized tax benefits in Provision for income taxes and Interest expense, respectively, in the Consolidated Statements of Operations and Comprehensive Income (Loss). As of December 31, 2016 and 2015, we have liabilities of $2.4 million and $2.3 million, respectively, for the possible payment of penalties and $11.0 million and $7.9 million, respectively, for the possible payment of interest expense, which are recorded in Other current liabilities in the Consolidated Balance Sheets.

Taxes have not been provided on undistributed earnings of subsidiaries where it is our intention to reinvest these earnings permanently or to repatriate the earnings only when it is tax effective to do so. It is not practicable to estimate the amount of tax that might be payable if such earnings were to be remitted.

Deferred taxes arise because of different treatment between financial statement accounting and tax accounting, known as "temporary differences." We record the tax effect of these temporary differences as "deferred tax assets" (generally items that can be used as a tax deduction or credit in future periods) and "deferred tax liabilities" (generally items for which we received a tax deduction but the tax impact has not yet been recorded in the Consolidated Statements of Operations and Comprehensive Income (Loss)).

Deferred taxes were recorded in the Consolidated Balance Sheets as follows:

As of December 31, 2016, tax loss carryforwards of $1,462.4 million were available to offset future income. A valuation allowance of $378.9 million exists for deferred income tax benefits related to the tax loss carryforwards which may not be realized. The increase in tax loss carryforwards and valuation allowance from 2015 to 2016 were primarily related to restructuring and interest expense. We believe sufficient taxable income will be generated in the respective jurisdictions to allow us to fully recover the remainder of the tax losses. The tax losses relate to Non-U.S. carryforwards of $1,388.0 million which are subject to varying expiration periods. Non-U.S. carryforwards of $1,130.6 million are located in jurisdictions with unlimited tax loss carryforward periods, while the remainder will begin to expire in 2017. In addition, there were no U.S. federal tax loss carryforwards and $74.4 million of state tax loss carryforwards as of December 31, 2016, which will expire in future years through 2036.

Tax sharing agreement

The 2012 Tax Sharing Agreement provides that we, Johnson Controls and ADT will share (i) certain pre-Distribution income tax liabilities that arise from adjustments made by tax authorities to our, Johnson Controls' and ADT's U.S. income tax returns, including withholding tax, income tax or other tax liabilities that could arise if the Merger, Distribution or certain internal transactions undertaken in anticipation of the Distribution are determined to be taxable for U.S. federal or Swiss tax purposes, and (ii) payments required to be made by Johnson Controls with respect to the 2007 Tax Sharing Agreement (the liabilities in clauses (i) and (ii) collectively, "Shared Tax Liabilities"). Johnson Controls is responsible for the first $500 million of Shared Tax Liabilities. As of December 31, 2016, Johnson Controls has paid $210.0 million of Shared Tax Liabilities. We and ADT will share 42% and 58%, respectively, of the next $225 million of Shared Tax Liabilities. We, ADT and Johnson Controls will share 20%, 27.5% and 52.5%, respectively, of Shared Tax Liabilities above $725 million. Costs and expenses associated with the management of Shared Tax Liabilities will generally be shared 20% by us, 27.5% by ADT and 52.5% by Johnson Controls. As of December 31, 2016, we have a liability of $13.3 million recorded for this matter in Other non-current liabilities in the Consolidated Balance Sheets.

In addition, under the terms of the 2012 Tax Sharing Agreement, in the event the Distribution, the ADT distribution, the internal transactions or the Merger were determined to be taxable as a result of actions taken after the Distribution by us, ADT or Johnson Controls, the party responsible for such failure would be responsible for all taxes imposed as a result thereof. If such failure is not the result of actions taken after the Distribution by us, ADT or Johnson Controls, then we, ADT and Johnson Controls would be responsible for any taxes imposed as a result of such determination in the same manner and in the same proportions as we, ADT and Johnson Controls are responsible for Shared Tax Liabilities.

13.	Benefit Plans

Pension and other post-retirement plans

We sponsor U.S. and Non-U.S. defined-benefit pension and other post-retirement plans. Pension benefits are based principally on an employee's years of service and/or compensation levels near retirement. In addition, we provide certain post-retirement health care and life insurance benefits. Generally, the post-retirement health care and life insurance plans require contributions from retirees. In December 2007, we announced that we will be freezing certain U.S. pension plans as of December 31, 2017.

The information herein relates to defined-benefit pension and other post-retirement plans of our continuing operations only.

Uncertainty in the securities markets and U.S. economy could result in investment returns less than those assumed. Should the securities markets decline or medical and prescription drug costs increase at a rate greater than assumed, we would expect increasing annual combined net pension and other post-retirement costs for the next several years. Should actual experience

Notes to consolidated financial statements

differ from actuarial assumptions, the projected pension benefit obligation and net pension cost and accumulated other post-retirement benefit obligation and other post-retirement benefit cost would be affected in future years.

Discount rates

The discount rate reflects the current rate at which the pension liabilities could be effectively settled at the end of the year based on our December 31 measurement date. The discount rate was determined by matching our expected benefit payments to payments from a stream of bonds rated AA or higher available in the marketplace, adjusted to eliminate the effects of call provisions. This produced a weighted-average discount rate for our U.S. pension plans of 4.02%, 4.21% and 3.63% in 2016, 2015 and 2014, respectively. The discount rates on our non-U.S. pension plans ranged from 0.50% to 4.00%, 0.50% to 4.25% and 0.50% to 4.25% in 2016, 2015 and 2014, respectively. There are no known or anticipated changes in our discount rate assumptions that will impact our pension expense in 2017.

Expected rates of return

Our expected rates of return on U.S. pension plan assets were 4.28%, 3.65% and 4.56% for 2016, 2015 and 2014, respectively. The expected rates of return on non-U.S. pension plan assets ranged from 1.00% to 5.50%, 1.00% to 6.00% and 1.00% to 6.00% in 2016, 2015 and 2014, respectively. The expected rate of return is designed to be a long-term assumption that may be subject to considerable year-to-year variance from actual returns. In developing the expected long-term rate of return, we considered our historical returns, with consideration given to forecasted economic conditions, our asset allocations, input from external consultants and broader longer-term market indices. U.S. pension plan assets yielded returns of 7.50%, (3.20)% and 22.30% in 2016, 2015 and 2014, respectively. As a result of our de-risking strategy to reduce U.S. pension plan liability, we anticipate the expected rate of return on our U.S. funded pension plans will continue to be consistent with the discount rate utilized. Any difference in the expected rate and actual returns will be included with the actuarial gain or loss recorded in the fourth quarter when our plans are remeasured.

Healthcare cost trend rates

The assumed healthcare cost trend rates for other post-retirement plans as of December 31 were as follows:



	2016		2015
Healthcare cost trend rate assumed for following year	7.0	%	7.4	%
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)	4.4	%	4.4	%
Year the cost trend rate reaches the ultimate trend rate	2038		2038

The assumed healthcare cost trend rates can have a significant effect on the amounts reported for healthcare plans. A one-percentage-point change in the assumed healthcare cost trend rates would have the following effects as of and for the year ended December 31, 2016:



	One Percentage Point

Objective

The primary objective of our investment strategy is to meet the pension obligation to our employees at a reasonable cost to us. This is primarily accomplished through growth of capital and safety of the funds invested.

During 2012, we adopted an investment strategy for our U.S. pension plans with a primary objective of preserving the funded status of the U.S. plans. This was achieved through investments in fixed interest instruments with interest rate sensitivity characteristics closely reflecting the interest rate sensitivity of our benefit obligations. Shifting of allocations away from equities to liability hedging fixed income investments, by reinvesting in fixed income instruments as equity investments were redeemed, was completed during 2013. As of December 31, 2016, the U.S. pension plans have an approximately 99 percent allocation to fixed income investments.

Asset allocation

Our actual overall asset allocation for our U.S. and non-U.S. pension plans as compared to our investment policy goals as of December 31 was as follows:

•	Cash and cash equivalents: Cash consists of cash held in bank accounts and was classified as Level 1. Cash equivalents consist of investments in commingled funds valued based on observable market data. Such investments were classified as Level 2.

•

Fixed income: Investments in corporate bonds, government securities, mortgages and asset backed securities were valued based upon quoted market prices for similar securities and other observable market data. Investments in commingled funds were generally valued at the net asset value of units held at the end of the period based upon the value of the underlying investments as determined by quoted market prices or by a pricing service. Such investments were classified as Level 2.


•	Global equity securities: Investments in commingled funds were valued at the net asset value of units held at the end of the period based upon the value of the underlying investments as determined by quoted market prices or by a pricing service. Such investments were classified as Level 2.

•

Other investments: Other investments include investments in commingled funds with diversified investment strategies. Investments in commingled funds that were valued at the net asset value of units held at the end of the period based upon the value of the underlying investments as determined by quoted market prices or by a pricing service were classified as Level 2. Investments in commingled funds that were valued based on unobservable inputs due to liquidation restrictions were classified as Level 3.

Activity for our Level 3 pension plan assets held during the years ended December 31, 2016 and 2015 was not material.

Cash flows

Contributions

Pension contributions totaled $10.0 million and $9.2 million in 2016 and 2015, respectively. Our 2017 pension contributions are expected to be approximately $22.0 million to $27.0 million. The 2017 expected contributions will equal or exceed our minimum funding requirements.

Estimated future benefit payments

The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid by the plans for the years ended December 31 as follows:



In millions	U.S. pension plans		Non-U.S. pension plans		Other post- retirement plans
2017	$	13.9	$	4.3	$	3.1

Savings plan

We have a 401(k) plan (the "401(k) plan") with an employee share ownership ("ESOP") bonus component, which covers certain union and all non-union U.S. employees who meet certain age requirements. Under the 401(k) plan, eligible U.S. employees may voluntarily contribute a percentage of their eligible compensation. We match contributions made by employees who meet certain eligibility and service requirements. Our matching contribution is 100% of eligible employee contributions for the first 1% of eligible compensation and 50% of the next 5% of eligible compensation.

In addition to the matching contribution, all employees who meet certain service requirements receive a discretionary ESOP contribution equal to 1.5% of annual eligible compensation.

Our combined expense for the 401(k) plan and the ESOP was $27.1 million, $26.5 million and $21.5 million in 2016, 2015 and 2014, respectively.

Other retirement compensation

Total other accrued retirement compensation, primarily related to deferred compensation and supplemental retirement plans, was $61.0 million and $65.8 million as of December 31, 2016 and 2015, respectively, and is included in Pension and other post-retirement compensation and benefits and Other non-current liabilities in the Consolidated Balance Sheets.

14.	Shareholders' Equity

Authorized shares

Our authorized share capital consists of 426.0 million ordinary shares with a par value of $0.01 per share.

Ordinary shares held in treasury

In August 2015, we canceled all of our ordinary shares held in treasury. At the time of the cancellation, we held 19.1 million ordinary shares in treasury at a cost of $1.2 billion.

Share repurchases

Prior to the closing of the Merger, our Board of Directors, and Tyco as our sole shareholder, authorized the repurchase of our ordinary shares with a maximum aggregate value of $400.0 million following the closing of the Merger. This authorization does not have an expiration date. In October 2012, the Board of Directors authorized the repurchase of our ordinary shares with a maximum dollar limit of $800.0 million. The authorization expired on December 31, 2015 and was in addition to the $400.0 million share repurchase authorization . There is no remaining availability under the 2012 authorizations.

In December 2014, the Board of Directors authorized the repurchase of our ordinary shares up to a maximum dollar limit of $1.0 billion. The authorization expires on December 31, 2019.

During the year ended December 31, 2015, we repurchased 3.1 million of our ordinary shares for $200.0 million under the 2014 authorization. We have $800.0 million remaining availability for repurchases under the 2014 authorization.

Dividends payable

On December 6, 2016, the Board of Directors declared a quarterly cash dividend of $0.345 that was paid on February 10, 2017 to shareholders of record at the close of business on January 27, 2017. Additionally, the Board of Directors approved a plan to increase the 2017 annual cash dividend to $1.38, which is intended to be paid in four quarterly installments. As a result, the balance of dividends payable included in Other current liabilities on our Consolidated Balance Sheets was $61.8 million at December 31, 2016. Dividends paid per ordinary share were $1.34, $1.28 and $1.10 for the years ended December 31, 2016, 2015 and 2014, respectively.

Share incentive plans

Prior to the Merger, our Board of Directors, and Tyco as our sole shareholder, approved the Pentair plc 2012 Stock and Incentive Plan (the "2012 Plan"). The 2012 Plan became effective on September 28, 2012 and authorizes the issuance of 9.0 million of our ordinary shares. The shares may be issued as new shares or from shares held in treasury. Prior to the cancellation of our shares held in treasury in August 2015, our practice was to settle equity-based awards from shares held in treasury. Subsequent to the cancellation, our practice is to settle equity-based awards by issuing new shares. The 2012 Plan terminates in September 2022. The 2012 Plan allows for the granting to our officers, directors, employees and consultants of non-qualified stock options, incentive stock options, stock appreciation rights, performance shares, performance units, restricted shares, restricted stock units, deferred stock rights, annual incentive awards, dividend equivalent units and other equity-based awards.

The 2012 Plan is administered by our compensation committee (the "Committee"), which is made up of independent members of our Board of Directors. Employees eligible to receive awards under the 2012 Plan are managerial, administrative or other key employees who are in a position to make a material contribution to the continued profitable growth and long-term success of our company. The Committee has the authority to select the recipients of awards, determine the type and size of awards,

Pentair plc and Subsidiaries

Notes to consolidated financial statements

establish certain terms and conditions of award grants and take certain other actions as permitted under the 2012 Plan. The 2012 Plan prohibits the Committee from re-pricing awards or cancelling and reissuing awards at lower prices.

The 2008 Omnibus Stock Incentive Plan as Amended and Restated (the "2008 Plan") terminated upon the completion of the Merger. Prior grants of restricted stock units and stock options made under the 2008 Plan and earlier stock incentive plans outstanding at completion of the Merger were converted into equity-based awards with respect to our ordinary shares and were assumed by us on the terms in effect at the time of grant and are outstanding under the 2012 Plan.

Non-qualified and incentive stock options

Under the 2012 Plan, we may grant stock options to any eligible employee with an exercise price equal to the market value of the shares on the dates the options were granted. Options generally vest over a three-year period commencing on the grant date and expire 10 years after the grant date.

Restricted shares and restricted stock units

Under the 2012 Plan, eligible employees may be awarded restricted shares or restricted stock units of our common stock. Restricted shares and restricted stock units generally vest one-third each year over a three-year period after issuance, subject to continuous employment and certain other conditions. Restricted shares and restricted stock units are valued at market value on the date of grant and are expensed over the vesting period.

Stock appreciation rights, performance shares and performance units

Under the 2012 Plan, the Committee is permitted to issue these awards which are generally earned over a three-year vesting period and tied to specific financial metrics. In December 2015, the Committee approved the grant of performance share units ("PSUs") to certain employees that vest based on the satisfaction of a three-year service period and the achievement of certain performance metrics over that same period. Upon vesting, PSU holders receive dividends that accumulate during the vesting period. The fair value of these PSUs is determined based on the closing market price of the Company's ordinary shares at the date of grant. Compensation expense is recognized over the period an employee is required to provide service based on the estimated vesting of the PSUs granted. The estimated vesting of the PSUs is based on the probability of achieving certain financial performance metrics during the three year vesting period.

Stock options

The following table summarizes stock option activity under all plans for the year ended December 31, 2016:



Shares and intrinsic value in millions	Number of shares		Weighted- average exercise price		Weighted- average remaining contractual life (years)	Aggregate intrinsic value
Outstanding as of January 1, 2016	5.6		$	42.55

Fair value of options granted

The weighted average grant date fair value of options granted under Pentair plans in 2016, 2015 and 2014 was estimated to be $9.74, $16.40 and $23.23 per share, respectively. The total intrinsic value of options that were exercised during 2016, 2015 and 2014 was $27.1 million, $20.8 million and $34.8 million, respectively. At December 31, 2016, the total unrecognized compensation cost related to stock options was $11.6 million. This cost is expected to be recognized over a weighted average period of 2.1 years.

Pentair plc and Subsidiaries

Notes to consolidated financial statements

We estimated the fair value of each stock option award on the date of grant using a Black-Scholes option pricing model, modified for dividends and using the following weighted average assumptions:



	December 31
	2016		2015		2014
Risk-free interest rate	1.56	%	1.60	%	1.44	%
Expected dividend yield	2.49	%	1.97	%	1.46	%
Expected share price volatility	27.3	%	30.4	%	35.3	%
Expected term (years)	5.9		6.0		5.6

These estimates require us to make assumptions based on historical results, observance of trends in our share price, changes in option exercise behavior, future expectations and other relevant factors. If other assumptions had been used, share-based compensation expense, as calculated and recorded under the accounting guidance, could have been affected.

We based the expected life assumption on historical experience as well as the terms and vesting periods of the options granted. For purposes of determining expected volatility, we considered a rolling average of historical volatility measured over a period approximately equal to the expected option term. The risk-free rate for periods that coincide with the expected life of the options is based on the U.S. Treasury Department yield curve in effect at the time of grant.

Cash received from option exercises for the years ended December 31, 2016, 2015 and 2014 was $31.6 million, $28.7 million and $46.6 million, respectively. The actual tax benefit realized for the tax deductions from option exercises totaled $5.5 million, $4.8 million and $8.3 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Restricted stock units

Vested	(0.5	)	52.37
Forfeited	—		—
Outstanding as of December 31, 2016	0.7		$	55.31

As of December 31, 2016, there was $29.1 million of unrecognized compensation cost related to restricted share compensation arrangements granted under the 2012 Plan and previous plans. That cost is expected to be recognized over a weighted-average period of 2.3 years. The total fair value of shares vested during the years ended December 31, 2016, 2015 and 2014, was $27.2 million, $26.0 million and $26.3 million, respectively. For the year ended December 31, 2016 there was no actual tax benefit realized. The actual tax benefit realized for the years ended December 31, 2015, and 2014 was $2.4 million and $3.1 million, respectively.

•	Flow & Filtration Solutions — The Flow & Filtration Solutions segment designs, manufactures, markets and services solutions for the toughest filtration, separation, flow and fluid management challenges in agriculture, food and beverage processing, water supply and disposal and a variety of industrial applications.

•

Technical Solutions — The Technical Solutions segment designs, manufactures, markets and services products that guard and protect some of the world's most sensitive electrical and electronic equipment, as well as heat management solutions designed to provide thermal protection to temperature sensitive fluid applications and engineered electrical and fastening products for electrical, mechanical and civil applications.


•	Other — Other is primarily composed of unallocated corporate expenses, our captive insurance subsidiary and intermediate finance companies.

During the first quarter of 2017, we reorganized our business segments to reflect a new operating structure, resulting in a change to our reporting segments in 2017. All segment information presented in this note and throughout this Annual Report on Form 10-K was prepared based on the reporting segments in place during 2016, unless otherwise noted.

The accounting policies of our reporting segments are the same as those described in the summary of significant accounting policies. We evaluate performance based on the net sales and segment income (loss) and use a variety of ratios to measure performance of our reporting segments. These results are not necessarily indicative of the results of operations that would have occurred had each segment been an independent, stand-alone entity during the periods presented. Segment income (loss) represents equity income of unconsolidated subsidiaries and operating income exclusive of intangible amortization, certain acquisition related expenses, costs of restructuring activities, "mark-to-market" gain/loss for pension and other post-retirement plans, impairments and other unusual non-operating items.

Net sales are based on the geographic destination of the sale. Long-lived assets represent property, plant and equipment, net of related depreciation. Net sales shipped to and long-lived assets held in Ireland for each year presented above were not material.

We offer a broad array of products and systems to multiple markets and customers for which we do not have the information systems to track revenues by primary product category. However, our net sales by segment are representative of our sales by major product category. We sell our products through various distribution channels including wholesale and retail distributors, original equipment manufacturers and home centers. No customer accounted for more than 10% of net sales in 2016, 2015, or 2014.

Asbestos matters

Notes to consolidated financial statements

actions. In addition, the amount does not include certain claims pending against third parties for which we have been provided an indemnification.

Periodically, we perform an analysis with the assistance of outside counsel and other experts to update our estimated asbestos-related assets and liabilities. Our estimate of the liability and corresponding insurance recovery for pending and future claims and defense costs is based on our historical claim experience and estimates of the number and resolution cost of potential future claims that may be filed. Our legal strategy for resolving claims also impacts these estimates.

Our estimate of asbestos-related insurance recoveries represents estimated amounts due to us for previously paid and settled claims and the probable reimbursements relating to our estimated liability for pending and future claims. In determining the amount of insurance recoverable, we consider a number of factors, including available insurance, allocation methodologies and the solvency and creditworthiness of insurers.

Our estimated liability for asbestos-related claims was $228.3 million and $237.9 million as of December 31, 2016 and 2015, respectively, and was recorded in Non-current liabilities held for sale in the Consolidated Balance Sheets for pending and future claims and related defense costs. Our estimated receivable for insurance recoveries was $108.5 million and $111.0 million, respectively, at December 31, 2016 and 2015 and was recorded in Non-current assets held for sale in the Consolidated Balance Sheets.

The amounts recorded by us for asbestos-related liabilities and insurance-related assets are based on our strategies for resolving our asbestos claims and currently available information as well as estimates and assumptions. Key variables and assumptions include the number and type of new claims filed each year, the average cost of resolution of claims, the resolution of coverage issues with insurance carriers, the amounts of insurance and the related solvency risk with respect to our insurance carriers, and the indemnifications we have provided to third parties. Furthermore, predictions with respect to these variables are subject to greater uncertainty in the latter portion of the projection period. Other factors that may affect our liability and cash payments for asbestos-related matters include uncertainties surrounding the litigation process from jurisdiction to jurisdiction and from case to case, reforms of state or federal tort legislation and the applicability of insurance policies among subsidiaries. As a result, actual liabilities or insurance recoveries could be significantly higher or lower than those recorded if assumptions used in our calculations vary significantly from actual results.

Environmental matters

We are involved in or have retained responsibility and potential liability for environmental obligations and legal proceedings related to our current business and, including pursuant to certain indemnification obligations, related to certain formerly owned businesses. We are responsible, or alleged to be responsible, for ongoing environmental investigation and/or remediation of sites in several countries. These sites are in various stages of investigation and/or remediation and at some of these sites our liability is considered de minimis. We received notification from the U.S. Environmental Protection Agency and from similar state and non-U.S. environmental agencies, that several sites formerly or currently owned and/or operated by us, and other properties or water supplies that may be or may have been impacted from those operations, contain disposed or recycled materials or waste and require environmental investigation and/or remediation. Those sites include instances where we have been identified as a potentially responsible party under U.S. federal, state and/or non-U.S. environmental laws and regulations. For several formerly owned businesses, we have also received claims for indemnification from purchasers of these businesses.

Our accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. It can be difficult to estimate reliably the final costs of investigation and remediation due to various factors. In our opinion, the amounts accrued are appropriate based on facts and circumstances as currently known. Based upon our experience, current information regarding known contingencies and applicable laws, we have recorded reserves for these environmental matters of $18.3 million and $22.8 million as of December 31, 2016 and 2015, respectively, which relate primarily to the Valves & Controls business classified as held for sale and were recorded in Other current liabilities held for sale and Other non-current liabilities held for sale in the Consolidated Balance Sheets.

We do not anticipate these environmental conditions will have a material adverse effect on our financial position, results of operations or cash flows. However, unknown conditions, new details about existing conditions or changes in environmental requirements may give rise to environmental liabilities that will exceed the amount of our current reserves and could have a material adverse effect in the future.

Notes to consolidated financial statements

Other matters

In addition to the matters described above, from time to time, we are subject to disputes, administrative proceedings and other claims arising out of the normal conduct of our business. These matters generally relate to disputes arising out of the use or installation of our products, product liability litigation, personal injury claims, commercial and contract disputes and employment related matters. On the basis of information currently available to it, management does not believe that existing proceedings and claims will have a material impact on our Consolidated Financial Statements. However, litigation is unpredictable, and we could incur judgments or enter into settlements for current or future claims that could adversely affect our financial statements.

Warranties and guarantees

In connection with the disposition of our businesses or product lines, we may agree to indemnify purchasers for various potential liabilities relating to the sold business, such as pre-closing tax, product liability, warranty, environmental, or other obligations. The subject matter, amounts and duration of any such indemnification obligations vary for each type of liability indemnified and may vary widely from transaction to transaction.

Generally, the maximum obligation under such indemnifications is not explicitly stated and as a result, the overall amount of these obligations cannot be reasonably estimated. Historically, we have not made significant payments for these indemnifications. We believe that if we were to incur a loss in any of these matters, the loss would not have a material effect on our financial condition or results of operations.

We recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee.

We provide service and warranty policies on our products. Liability under service and warranty policies is based upon a review of historical warranty and service claim experience. Adjustments are made to accruals as claim data and historical experience warrant.

The changes in the carrying amount of service and product warranties for the years ended December 31, 2016 and 2015 were as follows:



	Years ended December 31
In millions	2016			2015
Beginning balance	$	47.0		$	51.8

Payments	(67.3		)	(60.4		)
Foreign currency translation	(0.5		)	(1.0		)
Ending balance	$	38.9		$	47.0

Stand-by letters of credit, bank guarantees and bonds

In certain situations, Tyco guaranteed Flow Control's performance to third parties or provided financial guarantees for financial commitments of Flow Control. In situations where Flow Control and Tyco were unable to obtain a release from these guarantees in connection with the spin-off of Flow Control from Tyco, we will indemnify Tyco for any losses it suffers as a result of such guarantees.
