Notes to the Consolidated Financial Statements

(Unaudited)

1. General

Basis of Presentation

The accompanying unaudited consolidated financial statements of AAON, Inc., a Nevada corporation, and our operating subsidiaries, all of which are wholly-owned, (collectively, the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the rules and regulations of the Securities and Exchange Commission (“SEC”). These financial statements have not been audited by the Company's independent registered public accounting firm, except that the consolidated balance sheet at December 31, 2016 is derived from audited consolidated financial statements. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The financial statements reflect all adjustments (all of which are of a normal recurring nature) which are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. Interim results are not necessarily indicative of the results that may be expected for a full year. Certain disclosures have been condensed in or omitted from these consolidated financial statements. The accompanying unaudited financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. All intercompany balances and transactions have been eliminated in consolidation.

We are engaged in the engineering, manufacturing, marketing and sale of air conditioning and heating equipment consisting of standard, semi-custom and custom rooftop units, chillers, packaged outdoor mechanical rooms, air handling units, makeup air units, energy recovery units, condensing units, geothermal/water-source heat pumps and coils.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Because these estimates and assumptions require significant judgment, actual results could differ from those estimates and could have a significant impact on our results of operations, financial position and cash flows. We reevaluate our estimates and assumptions as needed, but at a minimum on a quarterly basis. The most significant estimates include, but are not limited to, the allowance for doubtful accounts, inventory reserves, warranty accrual, worker's compensation accrual, medical insurance accrual, income taxes and share-based compensation. Actual results could differ materially from those estimates.

Accounting Policies

A comprehensive discussion of our critical accounting policies and management estimates is included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2016.

Recent Accounting Pronouncements

Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of Accounting Standards Updates ("ASUs") to the FASB's Accounting Standards Codification.

We consider the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial statements and notes thereto.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, with the issuance of ASU 2015-14, the FASB amended the effective date for public companies to January 1, 2018.

The following ASUs were issued in 2016 along with ASU 2014-09 with the same effective dates and transition requirements:


•	ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which provides implementation guidance for Topic 606 on principal versus agent considerations.

- 5 -


•	ASU 2016-10, Identifying Performance Obligations and Licensing, which provides clarification for two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance.


•	ASU 2016-12, Revenue from Contracts with Customers, which further amends Topic 606.


•	ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which further amends Topic 606.

The Company plans to adopt using the retrospective transition method. The Company believes the impact will not be material to the consolidated financial statements. The Company has reviewed all types of customer contracts and gone through the five step process outlined in ASU 2014-09 for all contracts. The new five step process required by ASU 2014-09 provides results substantially consistent with our current revenue recognition policies. The Company is still in the process of determining categories to use to disaggregate revenue. The primary change upon adoption will be additional disclosures to show disaggregated revenue and further details around our revenue recognition process. Once we adopt ASU 2014-09, we do not anticipate that our internal control framework will materially change, but rather that existing internal controls will be modified and augmented, as necessary, to consider our new revenue recognition policy effective January 1, 2018.

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which will address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The ASU becomes effective in the annual reporting period beginning after December 31, 2017, including interim reporting periods. We do not expect ASU 2016-01 will have a material effect on our consolidated financial statements and notes thereto.

In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting, which addresses changes to the terms or conditions of a share-based payment award. The ASU becomes effective in the annual reporting period beginning after December 15, 2017, including interim reporting periods. We do not expect ASU 2017-09 will have a material effect on our consolidated financial statements and notes thereto.

2. Revenue Recognition

We recognize revenues from sales of products when the title and risk of ownership pass to the customer. Final sales prices are fixed based on purchase orders. Sales allowances and customer incentives are treated as reductions to sales and are provided for based on historical experiences and current estimates. Sales of our products are moderately seasonal with the peak period being July - November of each year.

In addition, the Company presents revenues net of sales tax and net of certain payments to our independent manufacturer representatives (“Representatives”). Representatives are national companies that are in the business of providing HVAC units and other related products and services to customers. The end user customer orders a bundled group of products and services from the Representative and expects the Representative to fulfill the order. Only after the specifications are agreed to by the Representative and the customer, and the decision is made to use an AAON HVAC unit, will we receive notice of the order. We establish the amount we must receive for our HVAC unit (“minimum sales price”), but do not control the total order price that is negotiated by the Representative with the end user customer.

We are responsible for billings and collections resulting from all sales transactions, including those initiated by our Representatives. The Representatives submit the total order price to us for invoicing and collection. The total order price includes our minimum sales price and an additional amount which may include both the Representatives’ fee and amounts due for additional products and services required by the customer. These additional products and services may include controls purchased from another manufacturer to operate the unit, start-up services, and curbs for supporting the unit (“Third Party Products”). All are associated with the purchase of a HVAC unit but may be provided by the Representative or another third party. The Company is under no obligation related to Third Party Products.

The Representatives’ fee and Third Party Products amounts (“Due to Representatives”) are paid only after all amounts associated with the order are collected from the customer. The amount of payments to our Representatives were $12.6 million and $15.8 million for the three months ended September 30, 2017 and 2016, respectively. The amounts of payments to our Representatives were $37.2 million and $43.5 million for the nine months ended September 30, 2017 and 2016, respectively.

The Company also sells extended warranties on parts for various lengths of time ranging from 6 months to 10 years. Revenue for these separately priced warranties is deferred and recognized on a straight-line basis over the separately priced warranty period.

3. Investments

Certificates of Deposit – We held approximately $5.0 million in certificates of deposit at September 30, 2017 and December 31, 2016, respectively. At September 30, 2017, the certificates of deposit bear interest ranging from 0.85% to 1.10% per annum and have various maturities ranging from less than one month to approximately 12 months.

Investments Held to Maturity – Our investments held to maturity are comprised of $11.3 million of corporate notes and bonds with original maturities ranging from less than two months to approximately 10 months. The investments have moderate risk with S&P ratings ranging from AAA to BBB-.

We record the amortized cost basis and accrued interest of the corporate notes and bonds in the Consolidated Balance Sheets. We record the interest and amortization of bond premium to interest income in the Consolidated Statements of Income.

The following summarizes the amortized cost and estimated fair value of our investments held to maturity as of

September 30, 2017 and December 31, 2016:

5. Inventories

Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out (“FIFO”) method. We establish an allowance for excess and obsolete inventories based on product line changes, the feasibility of substituting parts and the need for supply and replacement parts.

7. Warranties

The Company has warranties with various terms ranging from 18 months for parts to 25 years for certain heat exchangers. The Company has an obligation to replace parts or service its products if conditions under the warranty are met. A provision is made for estimated warranty costs at the time the related products are sold based upon the warranty period, historical trends, new products and any known identifiable warranty issues.

The Company has been working on modifications and refinements to its warranty policy. These modifications more clearly define what qualifies as a warranty claim and place a deadline for when claims may be submitted. This has increased our warranty reserve and increased our warranty expense for the three and nine months ended September 30, 2017, as detailed below.

9. Revolving Credit Facility

Our revolving credit facility, which is provided by BOKF, NA dba Bank of Oklahoma, formerly known as Bank of Oklahoma, N.A. ("Bank of Oklahoma"), provides for maximum borrowings of $30.0 million. Under the line of credit, there is one standby letter of credit totaling $0.8 million. Borrowings available under the revolving credit facility at September 30, 2017 were $29.2 million. Interest on borrowings is payable monthly at LIBOR plus 2.5%. No fees are associated with the unused portion of the committed amount. We had no outstanding balance under the revolving credit facility at September 30, 2017 and December 31, 2016. The termination date of the revolving credit facility is July 27, 2018.

As of September 30, 2017, we were in compliance with our financial covenants. These covenants require that we meet certain parameters related to our tangible net worth and total liabilities to tangible net worth ratio. At September 30, 2017, our tangible net worth was $230.3 million and met the requirement of being at or above $125.0 million. Our total liabilities to tangible net worth ratio was 0.32 to 1, and met the requirement of not being above 2 to 1.

	September 30, 2017		September 30, 2016		September 30, 2017		September 30, 2016
Federal statutory rate	35.0	%	35.0	%	35.0	%	35.0	%
State income taxes, net of Federal benefit	5.3		4.9		4.5		5.0
Domestic manufacturing deduction	(3.1	)	(3.0	)	(3.0	)	(3.4	)
Excess tax benefits	(0.9	)	(2.8	)	(3.8	)	(2.9	)
Other	(1.0	)	(3.0	)	(0.6	)	(1.3	)
Effective tax rate	35.3	%	31.1	%	32.1	%	32.4	%

The Company's estimated annual 2017 effective tax rate, excluding discrete events, is approximately 36%. We file income tax returns in the U.S., state and foreign income tax returns jurisdictions. We are subject to U.S. examinations for tax years 2013 to present, and to non-U.S. income tax examinations for the tax years of 2012 to present. In addition, we are subject to state and local income tax examinations for the tax years 2012 to present. The Company continues to evaluate its need to file returns in various state jurisdictions. Any interest or penalties would be recognized as a component of income tax expense.

11. Share-Based Compensation

On May 22, 2007, our stockholders adopted a Long-Term Incentive Plan (“LTIP”) which provided an additional 3.3 million shares that could be granted in the form of stock options, stock appreciation rights, restricted stock awards, performance units and performance awards. Since inception of the LTIP, non-qualified stock options and restricted stock awards were granted with the same vesting schedule as the previous plan. Under the LTIP, the exercise price of shares granted could not be less than 100% of the fair market value at the date of the grant.

On May 24, 2016, our stockholders adopted the 2016 Long-Term Incentive Plan ("2016 Plan") which provides for approximately 3.8 million shares, comprised of 3.4 million new shares provided for under the 2016 Plan and approximately 0.4 million shares that were available for issuance under the previous LTIP, that are now authorized for issuance under the 2016 Plan, that can be granted in the form of stock options, stock appreciation rights, restricted stock awards, performance awards, dividend equivalent rights, and other awards. Under the 2016 Plan, the exercise price of shares granted may not be less than 100% of the fair market value at the date of the grant. The 2016 Plan will be administered by the Compensation Committee of the Board of Directors or such other committee of the Board of Directors as is designated by the Board of Directors (the “Committee”). Membership on the Committee shall be limited to independent directors. The Committee may delegate certain duties to one or more officers of the Company as provided in the 2016 Plan. The Committee will determine the persons to whom awards are to be made, determine the type, size and terms of awards, interpret the 2016 Plan, establish and revise rules and regulations relating to the 2016 Plan and make any other determinations that it believes necessary for the administration of the 2016 Plan.

The compensation cost related to unvested stock options not yet recognized as of September 30, 2017 is $9.3 million and is expected to be recognized over a weighted-average period of 2.40 years.

The following weighted average assumptions were used to determine the fair value of the stock options granted on the original grant date for expense recognition purposes for options granted during the nine months ended September 30, 2017 and 2016 using a Black Scholes Model:



	Nine months ended
	September 30, 2017			September 30, 2016
Director and Officers:
Expected dividend rate	$	0.26		$	0.22
Expected volatility	30.81		%	42.38		%
Risk-free interest rate	1.90		%	2.02		%
Expected life (in years)	5.0			8.0

Employees:
Expected dividend rate	$	0.26		$	0.22
Expected volatility	30.70		%	40.41		%
Risk-free interest rate	1.88		%	1.60		%
Expected life (in years)	5.0			7.3

The expected term of the options is based on evaluations of historical and expected future employee exercise behavior. The risk-free interest rate is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected life at the grant date. Volatility is based on historical volatility of our stock over time periods equal to the expected life at grant date.

The following is a summary of stock options vested and exercisable as of September 30, 2017:



Range of Exercise Prices	Number of Shares	Weighted Average Remaining Contractual Life (in years)	Weighted Average Exercise Price		Intrinsic Value (in thousands)

A summary of option activity under the plans is as follows:



Options	Shares		Weighted Average Exercise Price
Outstanding at December 31, 2016	1,450,704		$	21.33
Granted	403,260		34.43
Exercised	(165,876	)	10.34
Forfeited or Expired	(85,326	)	30.63
Outstanding at September 30, 2017	1,602,762		$	25.27
Exercisable at September 30, 2017	416,282		$	12.42

The total intrinsic value of options exercised during the nine months ended September 30, 2017 and 2016 was $4.2 million and $4.3 million, respectively. The cash received from options exercised during the nine months ended September 30, 2017 and 2016 was $1.7 million in each period. The impact of these cash receipts is included in financing activities in the accompanying Consolidated Statements of Cash Flows.

Since 2007, as part of the LTIP and since May 2016 as part of the 2016 Plan, the Compensation Committee of the Board of Directors has authorized and issued restricted stock awards to directors and key employees. Restricted stock awards granted to directors vest one-third each year. All other restricted stock awards vest at a rate of 20% per year. The fair value of restricted stock awards is based on the fair market value of AAON, Inc. common stock on the respective grant dates, reduced for the present value of dividends.

These awards are recorded at their fair value on the date of grant and compensation cost is recorded using straight-line vesting over the service period. At September 30, 2017, unrecognized compensation cost related to unvested restricted stock awards was approximately $7.4 million, which is expected to be recognized over a weighted average period of 1.9 years.

A summary of the unvested restricted stock awards is as follows:



Restricted stock	Shares		Weighted Average Grant Date Fair Value
Unvested at December 31, 2016	408,162		$	20.47
Granted	123,151		33.96

12. Earnings Per Share

Basic net income per share is calculated by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share assumes the conversion of all potentially dilutive securities and is calculated by dividing net income by the sum of the weighted average number of shares of common stock outstanding plus all potentially dilutive securities. Dilutive common shares consist primarily of stock options and restricted stock awards.

ASU 2016-09 impacts the calculation of diluted weighted average shares under the treasury stock method as the Company no longer increases or decreases the assumed proceeds from an employee vesting in, or exercising, a share-based payment award by the amount of excess tax benefits or deficiencies taken to additional paid-in capital.

13. Stockholders’ Equity

Stock Repurchase - The Board has authorized three stock repurchase programs for the Company. The Company may purchase shares on the open market from time to time, up to a total of 5.7 million shares. The Board must authorize the timing and amount of these purchases. Effective May 24, 2016, the Board authorized up to $25.0 million in open market repurchases and on June 2, 2016, the Company executed a repurchase agreement in accordance with the rules and regulations of the SEC allowing the Company to repurchase an aggregate amount of $25.0 million or a total of approximately 2.0 million shares from the open market. The agreement expired on April 15, 2017. The Company also has a stock repurchase arrangement by which employee-participants in our 401(k) savings and investment plan are entitled to have shares in AAON, Inc. stock in their accounts sold to the Company. The maximum number of shares to be repurchased is contingent upon the number of shares sold by employee-participants. Lastly, the Company repurchases shares of AAON, Inc. stock from certain of its directors and employees for payment of statutory tax withholdings on stock transactions. Al1 other repurchases from directors or employees are contingent upon Board approval. All repurchases are done at current market prices.

Our repurchase activity is as follows:

14. Commitments and Contingencies

We are subject to various claims and legal actions that arise in the ordinary course of business. We closely monitor these claims and legal actions and frequently consult with our legal counsel to determine whether they may, when resolved, have a material adverse effect on our financial position, results of operations or cash flows and we accrue and/or disclose loss contingencies as appropriate. We have concluded that the likelihood is remote that the ultimate resolution of any pending litigation or claims will be material or have a material adverse effect on the Company's business, financial position, results of operations or cash flows.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the notes thereto, which are included in this report, and our audited consolidated financial statements and the notes thereto, which are included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016. This discussion contains or incorporates by reference “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are not historical facts, but rather are based on expectations, estimates, assumptions and projections about our industry, business and future financial results, based on information available at the time this report is filed with the SEC or, with respect to any document incorporated by reference, available at the time that such document was prepared. Our actual results could differ materially from the results contemplated by these forward-looking statements due to a number of factors, including those identified in the section entitled “Forward-Looking Statements” in this Item 2 of this Quarterly Report on Form 10-Q and in the section entitled “Risk Factors” in Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016. We do not assume any obligation to update or revise any forward-looking statements to reflect changed assumptions, the occurrence of anticipated or unanticipated events, new information or circumstances or otherwise, except as required by law.

Overview

We engineer, manufacture and market air conditioning and heating equipment consisting of standard, semi-custom and custom rooftop units, chillers, packaged outdoor mechanical rooms, air handling units, makeup air units, energy recovery units, condensing units, geothermal/water-source heat pumps and coils. These products are marketed and sold to retail, manufacturing, educational, lodging, supermarket, medical and other commercial industries. We market our products to all 50 states in the United States and certain provinces in Canada. Foreign sales were approximately $11.4 million of our total net sales for the nine months just ended and $11.1 million of our sales during the same period of 2016.

Our business can be affected by a number of economic factors, including the level of economic activity in the markets in which we operate. The uncertainty of the economy has negatively impacted the commercial and industrial new construction markets. A further decline in economic activity could result in a decrease in our sales volume and profitability. Sales in the commercial and industrial new construction markets correlate closely to the number of new homes and buildings that are built, which in turn is influenced by cyclical factors such as interest rates, inflation, consumer spending habits, employment rates and other macroeconomic factors over which we have no control.

We sell our products to property owners and contractors through a network of manufacturers’ representatives and our internal sales force. The demand for our products is influenced by national and regional economic and demographic factors. The commercial and industrial new construction market is subject to cyclical fluctuations in that it is generally tied to housing starts, but has a lag factor of six to 18 months. Housing starts, in turn, are affected by such factors as interest rates, the state of the economy, population growth and the relative age of the population. When new construction is down, we emphasize the replacement market. The new construction market in 2016 through the third quarter of 2017 continued to be unpredictable and uneven. Thus, we continue to emphasize promotion of the benefits of AAON equipment to property owners in the replacement market.

The principal components of cost of goods sold are labor, raw materials, component costs, factory overhead, freight and engineering expense. The principal high volume raw materials used in our manufacturing processes are steel, copper and aluminum, and are obtained from domestic suppliers. We also purchase from domestic manufacturers certain components, including compressors, motors and electrical controls.

The price levels of our raw materials have remained relatively consistent the past few years, but the market continues to be volatile and unpredictable as a result of the uncertainty related to the U.S. economy and a weakening global economy. For the nine months ended September 30, 2017, the price for copper, galvanized steel, stainless steel and aluminum increased by approximately 2.7%, 13.5%, 2.6% and 1.8%, respectively, for the nine months ended September 30, 2016.

In 2015, AAON initiated the design of a new Water Source Heat Pump product line and its affiliated manufacturing facility. We have brought the product into the marketplace and are in the final stages of completing this introduction into a $500-$600 million new market.

In 2016, we began construction of a 162,000 square foot laboratory building with ten testing cells contained within it. This unique laboratory will have capabilities beyond anything known to exist in the world and will elevate AAON's research and design capabilities accordingly. Completion of this lab in 2018 will therefore be quite significant.

- 15 -

The following are recent highlights and items that impacted our results of operations, cash flows and financial condition:


•	Overall units sold increased approximately 7.7% as compared to the same period last year.


•	We invested $26.4 million in capital expenditures in connection with the construction of our new research and development lab, water source heat pump line and other internal projects.


•	Increased warranty costs due to modifications and refinements in our policy, which are expected to be short-term.

The overall increase in SG&A was primarily due to increased warranty expenses. The Company has been working on modifications and refinements to its warranty policy. These modifications more clearly define what qualifies as a warranty claim and place a deadline for when claims may be submitted. This has increased our warranty reserve and increased our warranty expense for the three months ended September 30, 2017.

The Company’s estimated annual 2017 effective tax rate, excluding discrete events, is expected to be approximately 36.0%. The rate is higher for the three months ended September 30, 2017 due to shifts in income to states with a higher tax rate and a smaller excess tax benefit from stock compensation.

The Company’s estimated annual 2017 effective tax rate, excluding discrete events, is expected to be approximately 36.0%. Our rate is lower than expected due to the impact of excess tax benefits on stock compensation.

Liquidity and Capital Resources

Our working capital and capital expenditure requirements are generally met through net cash provided by operations and the occasional use of our revolving credit facility.

Our cash and investments decreased $3.9 million from December 31, 2016 to September 30, 2017 and totaled $39.9 million at September 30, 2017.

Under the line of credit, there was one standby letter of credit of $0.8 million as of September 30, 2017. At September 30, 2017, we have $29.2 million of borrowings available under the revolving credit facility. No fees are associated with the unused portion of the committed amount.

We had no outstanding balance under the revolving credit facility at September 30, 2017 and December 31, 2016. Interest on borrowings is payable monthly at LIBOR plus 2.5%. The termination date of the revolving credit facility is July 27, 2018.

At September 30, 2017, we were in compliance with all of the covenants under the revolving credit facility. We are obligated to comply with certain financial covenants under the revolving credit facility. These covenants require that we meet certain parameters related to our tangible net worth and total liabilities to tangible net worth ratio. At September 30, 2017, our tangible net worth was $230.3 million, which meets the requirement of being at or above $125.0 million. Our total liabilities to tangible net worth ratio was 0.32 to 1.0 which meets the requirement of not being above 2 to 1.

Authorizations - The Board has authorized three stock repurchase programs for the Company. The Company may purchase shares on the open market from time to time, up to a total of 5.7 million shares. The Board must authorize the timing and amount of these purchases. Effective May 24, 2016, the Board authorized up to $25.0 million in open market repurchases and on June 2, 2016, the Company executed a repurchase agreement in accordance with the rules and regulations of the SEC allowing the Company to repurchase an aggregate amount of $25.0 million or a total of approximately 2.0 million shares from the open market. The agreement expired on April 15, 2017. The Company also has a stock repurchase arrangement by which employee-participants in our 401(k) savings and investment plan are entitled to have shares in AAON, Inc. stock in their accounts sold to the Company. The maximum number of shares to be repurchased is contingent upon the number of shares sold by employee-participants. Lastly, the Company repurchases shares of AAON, Inc. stock from certain of its directors and employees for payment of statutory tax withholdings on stock transactions. Any other repurchases from directors or employees are contingent upon Board approval. All repurchases are done at current market prices.

Cash Flows Provided by Operating Activities

Cash outflows for inventory purchases has increased related to increased volume of unit sales as well as for new production on our Water Source Heat Pump line. Cash outflows from receivables has also increased as we've seen activity in our prepayment program decrease slightly and sales slightly increase too.

Cash Flows Provided by Investing Activities

Our capital expenditures continue to increase with new equipment for our various product lines and construction on our research and development lab. The capital expenditure program for 2017 is estimated to be approximately $48.5 million.

Cash Flows Used in Financing Activities

While the number of shares repurchased remained relatively consistent as compared to the prior year, the increase in the Company's share price drove the increased cash outflows for buyback activity.

Words such as “expects”, “anticipates”, “intends”, “plans”, “believes”, “seeks”, “estimates”, “will”, “should”, and variations of such words and similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions, which are difficult to predict.

Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they are made. We undertake no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Important factors that could cause results to differ materially from those in the forward-looking statements include (1) the timing and extent of changes in raw material and component prices, (2) the effects of fluctuations in the commercial/industrial new construction market, (3) the timing and extent of changes in interest rates, as well as other competitive factors during the year, and (4) general economic, market or business conditions.
