PART I

Item 1. Business.

General Development and Description of Business

AAON, Inc., a Nevada corporation, was incorporated on August 18, 1987. We have two operating subsidiaries, AAON, Inc., an Oklahoma corporation and AAON Coil Products, Inc., a Texas corporation. Unless the context otherwise requires, references in this Annual Report to “AAON,” the “Company”, “we”, “us”, “our”, or “ours” refer to AAON, Inc., and our subsidiaries.

We are engaged in the manufacture and sale of air-conditioning and heating equipment. Our products consist of rooftop units, chillers, air-handling units, make-up air units, heat recovery units, condensing units, commercial-self contained units and coils.

Products and Markets

Our products serve the commercial and industrial new construction and replacement markets. To date, our sales have been primarily to the domestic market. Foreign sales accounted for approximately 5% of our sales in 2012.

Our rooftop and condenser markets consist of units installed on commercial or industrial structures of generally less than 10 stories in height. Our air-handling units, commercial self-contained units, chillers, and coils are applicable to all sizes of commercial and industrial buildings.

The size of these markets is determined primarily by the number of commercial and industrial building completions. The replacement market consists of products installed to replace existing units/components that are worn or damaged. Currently, slightly over half of the industry's market consists of replacement units.

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 6-18 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.

Based on our 2012 level of sales of $303.1 million, we estimate that we have approximately a 14% share of the rooftop market and a 1% share of the coil market. Approximately 55% of our sales were generated from the sale to the renovation and replacement markets and 45% from new construction. The percentage of sales for new construction vs. replacement to particular customers is related to the customer’s stage of development.

We purchase certain components, fabricate sheet metal and tubing and then assemble and test the finished products. Our primary finished products consist of a single unit system containing heating, cooling and/or heat recovery components in a self-contained cabinet, referred to in the industry as "unitary products”. Our other finished products are chillers, coils, air-handling units, condensing units, make-up air units, heat recovery units and commercial self-contained units.

We offer four groups of rooftop units. The RQ Series consisting of six cooling sizes ranging from one to six tons; the RN Series offered in 18 cooling sizes ranging from six to 70 tons, and an expansion of the RN series introduced in 2012 that increased the cooling range up to 140 tons and the number of cooling sizes from 18 to 26. The RL Series, which is offered in 15 cooling sizes ranging from 40 to 230 tons; and the HA Series, which is a horizontal discharge package for either rooftop or ground installation offered in eight sizes ranging from seven and one-half to 50 tons. We also offer the SA and SB models as an indoor package water cooled units with cooling capacities of 3 to 70 tons.

We manufacture a Model LC Chiller, air cooled, and a Model LL chiller, which is available in both air-cooled condensing and evaporative cooled configurations covering a range of 3 to 540 tons.

Our air-handling units consist of the F1 and H3/V3 Series and the modular (M2 and M3) Series as well as air handling unit versions of the RN, RL and SA units.

Our heat recovery option applicable to our RQ, RN and RL units, as well as our M2 and M3 Series air handlers, respond to the U.S. Clean Air Act mandate to increase fresh air in commercial structures. Our products are designed to compete on the higher quality end of standardized products.

Performance characteristics of our products range in cooling capacity from 1½ to 540 tons and in heating capacity from 69,000 - 9,000,000 BTU's. All of our products meet the Department of Energy's (“DOE”) minimum efficiency standards, which define the maximum amount of energy to be used in producing a given amount of cooling. Many of our units far exceed these minimum standards and are among the highest efficiency units currently available.

A typical commercial building installation requires a ton of air-conditioning for every 300-400 square feet or, for a 100,000 square foot building, 250 tons of air-conditioning, which can involve multiple units.

Major Customers

No customer accounted for 10% of our sales during 2012, 2011 or 2010.

Sources and Availability of Raw Materials

The most important materials we purchase are steel, copper and aluminum, which are obtained from domestic suppliers. We also purchase from other domestic manufacturers certain components, including compressors, electric motors and electrical controls used in our products. We attempt to obtain the lowest possible cost in our purchases of raw materials and components, consistent with meeting specified quality standards. We are not dependent upon any one source for raw materials or the major components of our manufactured products. By having multiple suppliers, we believe that we will have adequate sources of supplies to meet our manufacturing requirements for the foreseeable future.

We attempt to limit the impact of increases in raw materials and purchased component prices on our profit margins by negotiating with each of our major suppliers on a term basis from six months to one year.

Distribution

We employ a sales staff of 20 individuals and utilize approximately 93 independent manufacturer representatives' organizations (“Representatives”) having 108 offices to market our products in the United States and Canada. We also have one international sales organization, which utilizes 12 distributors in other countries. Sales are made directly to the contractor or end user, with shipments being made from our Tulsa, Oklahoma and Longview, Texas plants to the job site.

Our products and sales strategy focus on niche markets. The targeted markets for our equipment are customers seeking products of better quality than offered, and/or options not offered, by standardized manufacturers.

To support and service our customers and the ultimate consumer, we provide parts availability through our sales offices and have factory service organizations at each of our plants. Also, a number of the Representatives we utilize have their own service organizations, which, in connection with us, provide the necessary warranty work and/or normal service to customers.

Our product warranty policy is: the earlier of one year from the date of first use or 18 months from date of shipment for parts only; an additional four years for compressors (if applicable); 15 years on aluminized steel gas-fired heat exchangers (if applicable); 25 years on stainless steel heat exchangers (if applicable); and 10 years on gas-fired heat exchangers in RL products (if applicable). Our warranty policy for the RQ series covers parts for two years from date of unit shipment and labor for one year from date of unit shipment.

Research and Development

Our products are engineered for performance, flexibility and serviceability. This has become a critical factor in competing in the heating, ventilation and air conditioning (“HVAC”) equipment industry. We must continually develop new and improved products in order to compete effectively and to meet evolving regulatory standards in all of our major product lines.

All of our R&D activities are self-sponsored, rather than customer-sponsored. R&D has involved the RQ, RN and RL (rooftop units), F1, H/V, M2 and M3 (air handlers), LC and LL (chillers), CB and CC (condensing units), SA (commercial self-contained units) and BL (boilers), as well as component evaluation and refinement, development of control systems and new product development. We incurred research and development expenses of approximately $3.6 million, $4.8 million, and $3.6 million in 2012, 2011 and 2010, respectively.

Backlog

Our current backlog as of March 1, 2013 was approximately $51.1 million compared to approximately $55.3 million as of March 1, 2012. The current backlog consists of orders considered by management to be firm and generally are filled on average within approximately 60 days to 92 days after an order is deemed to become firm; however, the orders are subject to cancellation by the customers.

Working Capital Practices

Working capital practices in the industry center on inventories and accounts receivable. Our management regularly reviews our working capital with a view of maintaining the lowest level consistent with requirements of anticipated levels of operation. Our greatest needs arise during the months of July - November, the peak season for inventory (primarily purchased material) and accounts receivable. Our working capital requirements are generally met by cash flow from operations and a bank revolving credit facility, which currently permits borrowings up to $30 million (currently unused). We believe that we will have sufficient funds available to meet our working capital needs for the foreseeable future.

Seasonality

Sales of our products are moderately seasonal with the peak period being July - November of each year.

Competition

In the standardized market, we compete primarily with Lennox International, Inc., Trane (Ingersoll Rand Limited), York (Johnson Controls Inc.) and Carrier (United Technologies Corporation). All of these competitors are substantially larger and have greater resources than we do. Our products compete on the basis of total value, quality, function, serviceability, efficiency, availability of product, product line recognition and acceptability of sales outlet. However, in new construction where the contractor is the purchasing decision maker, we are often at a competitive disadvantage because of the emphasis placed on initial cost. In the replacement market and other owner-controlled purchases, we have a better chance of getting the business since quality and long-term cost are generally taken into account.

Employees

As of March 1, 2013, we employed 1,392 permanent employees and 4 temporary employees. Our employees are not currently represented by unions. Management considers its relations with our employees to be good.

Patents, Trademarks, Licenses and Concessions

We do not consider any patents, trademarks, licenses or concessions to be material to our business operations, other than patents issued regarding our heat recovery wheel option, blower, gas-fired heat exchanger and evaporative condenser desuperheater which have terms of twenty years with expiration dates ranging from 2016 to 2022.

Environmental Matters

Laws concerning the environment that affect or could affect our domestic operations include, among others, the Clean Water Act, the Clean Air Act, the Resource Conservation and Recovery Act, the Occupational Safety and Health Act, the National Environmental Policy Act, the Toxic Substances Control Act, regulations promulgated under these Acts, and any other federal, state or local laws or regulations governing environmental matters. We believe that we are in compliance with these laws and that future compliance will not materially affect our earnings or competitive position.

Our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act of 1934 will be available through our Internet website as soon as reasonably practical after we electronically file such material with, or furnish it to, the SEC.

Item 1A. Risk Factors.

The following risks and uncertainties may affect our performance and results of operations.

Our business can be hurt by economic conditions.

Our business is affected by a number of economic factors, including the level of economic activity in the markets in which we operate. Since 2008, the state of the United States economy has negatively impacted the commercial and industrial new construction markets. The decline in economic activity in the United States has materially affected our financial condition and results of operations. Sales in the commercial and industrial new construction markets correlate 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. In the HVAC business, a decline in economic activity as a result of these cyclical or other factors typically results in a decline in new construction and replacement purchases; but, thus far, has not resulted in a decrease in our sales volume and profitability.

We may be adversely affected by problems in the availability, or increases in the prices, of raw materials and components.

Problems in the availability, or increases in the prices, of raw materials or components could depress our sales or increase the costs of our products. We are dependent upon components purchased from third parties, as well as raw materials such as steel, copper and aluminum. Occasionally, we enter into cancelable and noncancelable contracts on terms from six months to one year for raw materials and components at fixed prices. However, if a key supplier is unable or unwilling to meet our supply requirements, we could experience supply interruptions or cost increases, either of which could have an adverse effect on our gross profit.

We risk having losses resulting from the use of non-cancelable fixed price contracts.

Historically, we attempted to limit the impact of price fluctuations on commodities by entering into non-cancelable fixed price contracts with our major suppliers for periods of 6 - 18 months. We expect to receive delivery of raw materials from our fixed price contracts for use in our manufacturing operations. These fixed price contracts are not accounted for as derivative instruments since they meet the normal purchases and sales exemption.

We may not be able to successfully develop and market new products.

Our future success will depend upon our continued investment in research and new product development and our ability to continue to realize new technological advances in the HVAC industry. Our inability to continue to successfully develop and market new products or our inability to achieve technological advances on a pace consistent with that of our competitors could lead to a material adverse effect on our business and results of operations.

We may incur material costs as a result of warranty and product liability claims that would negatively affect our profitability.

The development, manufacture, sale and use of our products involve a risk of warranty and product liability claims. Our product liability insurance policies have limits that, if exceeded, may result in material costs that would have an adverse effect on our future profitability. In addition, warranty claims are not covered by our product liability insurance and there may be types of product liability claims that are also not covered by our product liability insurance.

We may not be able to compete favorably in the highly competitive HVAC business.

Competition in our various markets could cause us to reduce our prices or lose market share, or could negatively affect our cash flow, which could have an adverse effect on our future financial results. Substantially all of the markets in which we participate are highly competitive. The most significant competitive factors we face are product reliability, product performance, service and price, with the relative importance of these factors varying among our product line. Other factors that affect competition in the HVAC market include the development and application of new technologies and an increasing emphasis on the development of more efficient HVAC products. Moreover, new product introductions are an important factor in the market categories in which our products compete. Several of our competitors have greater financial and other resources than we have, allowing them to invest in more extensive research and development. We may not be able to compete successfully against current and future competition and current and future competitive pressures faced by us may materially adversely affect our business and results of operations.

The loss of Norman H. Asbjornson could impair the growth of our business.

Norman H. Asbjornson, our founder, has served as our President and Chief Executive Officer from inception to date. He has provided the leadership and vision for our growth. Although important responsibilities and functions have been delegated to other highly experienced and capable management personnel, and our products are technologically advanced and well positioned for sales into the future, his death, disability or retirement could impair the growth of our business. We do not have an employment agreement with Mr. Asbjornson.

It should be noted, however, that the Board of Directors is in the process of evolving a succession plan relating to Mr. Asbjornson and the positions currently held by him.

Our business is subject to the risks of interruptions by problems such as computer viruses.

We depend upon information technology infrastructure, including network, hardware and software systems to conduct our business. Despite our implementation of network and other cyber security measures, our information technology system and networks could be disrupted or experience a security breach from computer viruses, break-ins and similar disruptions from unauthorized tampering with our computer systems. Any such event could have a material adverse effect on our business.

Exposure to environmental liabilities could adversely affect our results of operations.

Our future profitability could be adversely affected by current or future environmental laws. We are subject to extensive and changing federal, state and local laws and regulations designed to protect the environment in the United States and in other parts of the world. These laws and regulations could impose liability for remediation costs and result in civil or criminal penalties in case of non-compliance. Compliance with environmental laws increases our costs of doing business. Because these laws are subject to frequent change, we are unable to predict the future costs resulting from environmental compliance.

Extreme governmental regulations.

We always face the possibility of new governmental regulations which could have a substantial or even extreme negative effect on our operations and profitability. Specifically, Final Rule, Regulatory Identification No. 1904-AC23, published on March 7, 2011, which, if fully implemented subsequent to the current extension to the implementation date of January 1, 2014, would have highly detrimental consequences to all industries involving sales of energy using products by imposing burdensome, excessive and, in part, impossible testing requirements.

In addition, several other intrusive component part regulations have been proposed recently. If these proposals become final rules, the effect would be the regulation of compressors and fans in products for which the DOE does not have current authority. This could affect equipment we currently manufacture and could have an impact on our product design, operations and profitability.

We are subject to adverse changes in tax laws.

Our tax expense or benefits could be adversely affected by changes in tax provisions, unfavorable findings in tax examinations or differing interpretations by tax authorities. We are unable to estimate the impact that current and future tax proposals and tax laws could have on our results of operations. We are currently subject to state and local tax examinations for which we do not expect any major assessments.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

As of December 31, 2012, we own approximately 1.5 million square feet of space for office, manufacturing, warehouse and assembly operations in Tulsa, Oklahoma and Longview, Texas. We believe that our facilities are well maintained and are in good condition and suitable for the conduct of our business.

Our plant and office facilities in Tulsa, Oklahoma, consist of a 342,000 sq. ft. building (327,000 sq. ft. of manufacturing/warehouse space and 15,000 sq. ft. of office space) located on a 12-acre tract of land at 2425 South Yukon Avenue (the “original facility”), and a 861,000 sq. ft. manufacturing/warehouse building and a 70,000 sq. ft. office building (the “expansion facility”) located on a 40-acre tract of land across the street from the original facility (2440 South Yukon Avenue). We own the original facility and the expansion facility. Both plants are of sheet metal construction.

Our manufacturing area is in heavy industrial type buildings, with total coverage by bridge cranes, containing manufacturing equipment designed for sheet metal fabrication and metal stamping. The manufacturing equipment contained in the facilities consists primarily of automated sheet metal fabrication equipment, supplemented by presses. Assembly lines consist of seven cart-type conveyor lines with variable line speed adjustment, which are motor driven. Subassembly areas and production line manning are based upon line speed.

Our operations in Longview, Texas, are conducted in a plant/office building at 203-207 Gum Springs Road, containing 258,000 sq. ft. on 14 acres. The manufacturing area (approximately 251,000 sq. ft.) is located in three 120-foot wide sheet metal buildings connected by an adjoining structure. The remaining 7,000 square feet are utilized as office space. The facility is built for light industrial manufacturing. An additional, contiguous 15 acres were purchased in 2004 and 2005 for future expansion. We own both the existing plant/office building, and the 15 acres designated for future expansion.

Item 3. Legal Proceedings.

We are not a party to any pending legal proceeding which management believes is likely to result in a material liability and no such action is contemplated by or, to the best of our knowledge, has been threatened against us.

Item 4. Mine Safety Disclosure.

Not applicable.

PART II

At the discretion of the Board of Directors we pay semi-annual cash dividends. Board approval is required to determine the date of declaration and amount for each semi-annual dividend payment. The Board of Directors approved dividend payments of $0.12 per share related to the 3-for-2 stock split effective June 13, 2011.

We declared dividends to shareholders of record at the close of business on June 11, 2012, which were paid on July 2, 2012. At a meeting of the Board of Directors on November 7, 2012, the Board declared a regular semi-annual cash dividend of $0.12 per share, and, in view of our strong financial position, the Board also declared a one-time special cash dividend of $0.12 per share. Both dividends were paid to shareholders of record at the close of business on December 3, 2012 and paid on December 24, 2012.

We paid cash dividends of $8.8 million, $5.9 million, and $9.2 million in 2012, 2011, and 2010, respectively.

On November 6, 2007, our Board of Directors authorized a stock buyback program, targeting repurchases of up to approximately 10% (2.7 million shares) of our outstanding stock from time to time in open market transactions. On May 12, 2010, we completed the stock buyback program. Through May 12, 2010, we repurchased a total of 2.7 million shares under this program for an aggregate price of $36.1 million, or an average price of $13.36 per share. We purchased the shares at current market prices.

On May 17, 2010, the Board authorized a new stock buyback program, targeting repurchases of up to approximately 5% (1.3 million shares) of our outstanding stock from time to time in open market transactions. Through June 28, 2010, we repurchased a total of approximately 0.718 million shares under this program for an aggregate price of $11.5 million, or an average price of $16.04 per share. We purchased the shares at current market prices. We did not repurchase any of our equity securities during 2012.

On July 1, 2005, we entered into a stock repurchase arrangement by which employee-participants in our 401(k) savings and investment plan are entitled to have shares of AAON stock in their accounts sold to us to provide diversification of their investments. The maximum number of shares to be repurchased is contingent upon the number of shares sold by employees. Through December 31, 2012, we repurchased approximately 1.9 million shares for an aggregate price of $25.1 million, or an average price of $13.38 per share. We purchased the shares at current market prices.

On November 7, 2006, the Board of Directors authorized us to repurchase shares from certain directors and officers following their exercise of stock options. The maximum number of shares to be repurchased is contingent upon the number of shares sold. Through December 31, 2012, we repurchased approximately 0.734 million shares for an aggregate price of $11.2 million, or an average price of $15.25 per share. We purchased the shares at current market prices.

Repurchases during the fourth quarter of 2012 were as follows:

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

Overview

We engineer, manufacture and market air-conditioning and heating equipment consisting of rooftop units, chillers, air-handling units, make-up air units, heat recovery units, condensing units, commercial self-contained units and coils. These products are marketed and sold to retail, manufacturing, educational, 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 5% of our 2012 sales.

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 recent state 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 6-18 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 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 moderated from the high prices we experienced a year ago, but the market continues to be volatile and unpredictable as a result of the uncertainty related to the U.S. economy, a weakening global economy, and November 2012’s presidential election. For the year ended December 31, 2012, the price for copper increased by approximately 0.5% and the cost for steel and aluminum decreased approximately 2.5% and 8.0% respectively, from a year ago. For the year ended December 31, 2011 prices for copper and steel increased approximately 3% and 10%, respectively from prior year, while the cost of aluminum decreased approximately 2%.

We attempt to limit the impact of price fluctuations on these materials by entering into cancelable and non-cancelable fixed price contracts with our major suppliers for periods of 6 to 18 months. We expect to receive delivery of raw materials from our fixed price contracts for use in our manufacturing operations. In addition, from time to time we use derivative contracts to partially mitigate the volatility in the prices for some of these commodities. We did not enter into a derivative contract for any of our key raw materials during the years ended December 31, 2012 and 2011.

The following are key highlights and events that impacted our results of operations, cash flows, and financial condition in 2012:

·	Net sales for 2012 were $303.1 million, the highest in the Company’s history, compared to $266.2 million in 2011. The increase in net sales can be attributed to gains in market share in the non-residential and replacement markets along with price increases introduced earlier in the year.

·	We estimate that we have captured approximately 14% share of the rooftop market and a 1% share of the coil market. Approximately 55% of our sales were generated from the sale to the renovation and replacement markets and 45% from new construction markets.

·	Income from operations was $44.2 million compared to $22.2 million in 2011. The increase in operational income can be attributed to higher sales and improved productivity during the year.

·	Net income for 2012 was $27.4 million, up by $13.4 million, compared to $14.0 million in 2011.

·	We paid $14.1 million in capital expenditures, a decrease of $21.8 million from 2011.

·	We paid cash dividends of $8.8 million in 2012 compared to $5.9 million in 2011. The 2012 dividends included a one-time special dividend of $0.12, in addition to the regular semi-annual dividend of $0.12, declared by the Board on November 7, 2012, due to our strong financial position.

Year Ended December 31, 2012 vs. Year Ended December 31, 2011

Net Sales

Net sales for the year ended December 31, 2012 increased by 13.9%, or $36.9 million to $303.1 million, compared with the same period in 2011. The increase in net sales was the result of the favorable reception to our new products, increased market share along with price increases introduced earlier in the year.

Gross Profit

Gross profit increased by 52.3%, or $24.2 million, to $70.5 million in 2012 compared to 2011. As a percentage of sales, gross profit was 23.3% and 17.4% in 2012 and 2011, respectively. The improvement in gross profit can be attributed to cost savings in raw materials, increased product prices, product mix and improved productivity.

The principal components of cost of goods sold are labor, raw materials, component costs, factory overhead, freight out and engineering expense. The principal high volume raw materials used in our manufacturing processes are steel, copper and aluminum, which are obtained from domestic suppliers. For the year ended December 31, 2012, the price for copper increased by approximately 0.5% and the cost for steel and aluminum decreased approximately 2.5% and 8.0% respectively, from a year ago.

Selling, General and Administrative Expenses

Selling, General and Administrative (“SG&A”) expenses increased by 17.7%, or $4.0 million, to $26.3 million in 2012 compared to 2011, and as a percentage of net sales, SG&A expenses increased to 8.7% in 2012 from 8.4% in 2011. The increase in SG&A is primarily due to higher profit sharing expense as a result of higher operating income before income taxes of approximately $2.5 million and higher employee salaries of approximately $2.1 million as a result of salary pay increases and management discretionary bonus incentive plan, partially offset by decreases in our warranty expenses of $0.6 million and advertising expenses of approximately $0.3 million.

Interest Expense

Interest expense was approximately $0.044 million and $0.277 million in 2012 and 2011, respectively. The decrease in interest expense of $0.233 million in 2012 from prior year was due to decreased borrowings on the revolving credit facility. During 2012 we borrowed $34.8 million from the revolving credit facility as compared to $82.1 million in 2011. Interest on borrowings is payable monthly at LIBOR plus 2.5%. For the year ended December 31, 2012, we paid a weighted average interest rate of approximately 2.8%.

Interest Income

Interest income decreased by approximately $0.012 million to $0.086 million in 2012 compared to the same period in 2011. The decrease was due primarily to the fact that we held investments from January of 2011 until November 2011, when the investments fully matured, and we did not purchase additional interest bearing investments until May of 2012.

Other Income (Expense)

Other income, net was $0.041 million for the year ended 2012, an increase of $0.518 million from $0.477 million of expense in 2011. The higher 2011 expense was primarily due to repair expenses related to roof damages to one of our manufacturing facilities in Tulsa, Oklahoma caused by a severe snowstorm in February 2011.

Year Ended December 31, 2011 vs. Year Ended December 31, 2010

Net Sales

Net sales for the year ended December 31, 2011 increased by 9%, or $21.7 million to $266.2 million, compared with the same period in 2010. The increase in net sales was the result of the favorable reception to our new products, a significant increase in the replacement market of approximately 10% over prior year, and increased market share.

Gross Profit

Gross profit decreased by 16.1%, or $8.9 million, to $46.3 million in 2011 compared to 2010. As a percentage of sales, gross profit was 17.4% and 22.6% in 2011 and 2010, respectively. The decrease in gross profit was caused by increases in raw material and component part costs of approximately 6% that we were unable to neutralize completely with price increases for some of our product lines, and increased labor costs and freight cost of 8% and 1%, respectively.

The principal components of cost of goods sold are labor, raw materials, component costs, factory overhead, freight out and engineering expense. The principal high volume raw materials used in our manufacturing processes are steel, copper and aluminum, which are obtained from domestic suppliers. For the year ended December 31, 2011 we experienced price increases in copper and steel of approximately 3% and 10%, and an overall price decrease in aluminum of approximately 2% as compared to 2010.

Selling, General and Administrative Expenses

Selling, General and Administrative (“SG&A”) expenses decreased by $0.236 million, or 1.0% to $22.3 million in 2011 compared to 2010, and as a percentage of net sales, SG&A expenses declined to 8.4% in 2011 from 9.2% in 2010. The decrease was primarily due to lower profit sharing expense of approximately $1.4 million as a result of lower operating income before income tax offset by increases in salaries and employee benefits of $0.6 million, and advertising expense and professional fees of approximately $0.6 million.

Interest Expense

Interest expense was approximately $0.277 million and $0.045 million in 2011 and 2010, respectively. The increase in interest expense of $0.232 million in 2011 from prior year was due to increased borrowings on the revolving credit facility. During 2011 we borrowed $82.1 million from the revolving credit facility as compared to $20.8 million in 2010. Interest on borrowings is payable monthly at LIBOR plus 2.5%. For the year ended December 31, 2011, we paid a weighted average interest rate of approximately 3.4%.

Interest Income

Interest income decreased by approximately $0.160 million to $0.098 million in 2011 compared to the same period in 2010. The decreased was due primarily to all of our investments maturing and no additional funds invested in 2011.

Other Income (Expense)

Other expense, net increased by $0.242 million to $0.477 million in 2011 from $0.235 million in 2010 due to repair expenses related to the snowstorm in February of 2011, as noted above.

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 the revolving bank line of credit based on our current liquidity at the time.

General

On July 29, 2012 we renewed the line of credit with the Bank of Oklahoma, National Association. The revolving line of credit matures on July 28, 2013. We expect to renew our line of credit in July 2013 with favorable terms as we do not anticipate a tightening of funds in the financial markets. Under the line of credit, there is one standby letter of credit of $0.9 million. At December 31, 2012 we have approximately $29.1 million of borrowings available under the revolving credit facility. No fees are associated with the unused portion of the committed amount.

As of December 31, 2012, there was no outstanding balance under the revolving credit facility and $4.6 million borrowings were outstanding at December 31, 2011. Interest on borrowings is payable monthly at LIBOR plus 2.5%. The weighted average interest rate was 2.8% and 3.4% for the years ended December 31, 2012 and 2011, respectively.

At December 31, 2012 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, total liabilities to tangible net worth ratio and working capital. At December 31, 2012 our tangible net worth was $138.1 million, which meets the requirement of being at or above $95.0 million. Our total liabilities to tangible net worth ratio was 0.4 to 1.0 which meets the requirement of not being above 2 to 1. Our working capital was $51.9 million, which meets the requirement of being at or above $40.0 million.

We repurchased shares of stock under our authorized stock buyback programs, employees’ 401(k) savings, investment plan, and from option exercises of our directors and officers in the open market in the amount of $6.7 million for 0.336 million shares, $3.7 million for 0.212 million shares and $19.5 million for approximately 1.2 million shares of stock in 2012, 2011 and 2010, respectively.

For the year ended December 31, 2012, 2011 and 2010 we paid cash dividends of $8.8 million, $5.9 million, and $9.2 million respectively.

Based on historical performance and current expectations, we believe our cash and cash equivalents balance, the projected cash flows generated from our operations, our existing committed revolving credit facility (or comparable financing) and our expected ability to access capital markets will satisfy our working capital needs, capital expenditures and other liquidity requirements associated with our operations in 2013 and the foreseeable future.

Statement of Cash Flows

The table below reflects a summary of our net cash flows provided by operating activities, net cash flows used in investing activities, and net cash flows used in financing activities for the years indicated.

	2012			2011			2010
	(in millions)

Net cash provided by operating activities	$	51.2		$	26.5		$	32.2
Net cash used in investing activities		(30.3	)		(24.5	)		(28.3	)
Net cash used in financing activities		(17.7	)		(4.3	)		(27.2	)

Cash Flows from Operating Activities

Net cash provided by operating activities was $51.2 million in 2012 compared to $26.5 million in 2011. This increase was due to higher net income and a favorable change in working capital. For the year ended December 31, 2012, net income increased by $13.5 million. For 2011, net income decreased by $7.9 million from 2010.

Significant fluctuations in working capital were as follows:

Inventory - less cash was used in 2012 as we experienced decreases in raw materials prices from the prior year end. Overall, inventories decreased $2.3 million to $32.6 million at December 31, 2012 compared to $34.9 million the previous year. More cash was used in 2011 as improved demand resulted in increased volume and higher prices for raw materials, component, and parts in our inventory balance as compared to 2010 resulting in decreased cash flows of $1.3 million.

Accounts receivable – increased by approximately $9.6 million from the prior year primarily as a result of increased sales. In 2011, we experienced improved collection rates as a result of targeted sales discounts for some of our selected customers. This resulted in a decrease in our accounts receivable balance of approximately $6.1 million from 2010.

Accrued liabilities – accrued liabilities increased cash flows by approximately $6.6 million due to an increase in customer product pre-payments and credits of approximately $2.1 million, an increase in payroll and employee benefit accruals of approximately $3.0 million and an increase in the accrual of amounts due to our representatives of approximately $1.5 million. Accrued liabilities decreased cash flows by approximately $3.0 million in 2011 due to changes in certain reserves estimates as a result of better and improved experience and a decreased in amounts due to our representatives offset by a slight increase in accrued payroll and employee benefits.

Cash Flows from Investing Activities

Net cash used in investing activities was $30.3 million for the year ended December 31, 2012 compared with net cash used in investing activities of $24.5 million in 2011. The change is primarily attributable to 2012 investments of $6.5 million in certificates of deposit and $11.7 million in corporate notes and bonds, proceeds from investments in 2012 of $1.3 million compared to approximately $10.9 million in 2011, offset by a decrease in capital expenditures of $21.7 million from the prior year. Net cash used in investing activities was $24.5 million for the year ended December 31, 2011 compared with $28.3 million in 2010. The change in investing activities is primarily attributable to the net proceeds from investments in 2011 that were offset by a net increase in capital expenditures during 2011.

Capital expenditures were $14.1 million, $35.9 million and $17.5 million in 2012, 2011 and 2010, respectively. Capital expenditures in 2012 were primarily investments in our manufacturing and production equipment to support our growth and improve efficiencies with equipment which combines the latest advancement in automation and laser technology.

The capital expenditure program for 2013 is estimated to be approximately $10 million. Many of these projects are subject to review and cancellation at the discretion of our CEO and Board of Directors without incurring substantial charges.

Cash Flows from Financing Activities

Net cash used in financing activities during the year ended December 31, 2012 was $17.7 million, compared with $4.3 million during 2011. The change in financing activities is primarily related to approximately $6.7 million of share repurchases as well as dividend payments of $8.8 million, and reduced borrowings and increased payments on our credit facility resulting in no outstanding borrowings at December 31, 2012.

Net cash used in financing activities during the year ended December 31, 2011 was $4.3 million, compared with $27.2 million during 2010. The change in financing activities is primarily related to approximately $3.7 million of share repurchases as well as dividend payments of $5.9 million, partially offset by an increase in net borrowing of approximately $4.6 million and stock options and restricted stock awards exercised.

Off-Balance Sheet Arrangements

We are not party to any off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues, expenses, results of operations, liquidity, capital expenditures or capital resources.

Commitments and Contractual Agreements

We have no material contractual agreements as of December 31, 2012.

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 or results of operations. While we are unable to estimate the ultimate dollar amount of exposure or loss in connection with these matters, we make accruals as warranted. We believe that we have adequately provided in our consolidated financial statements for the potential impact of these contingencies. We also believe that the outcomes will not significantly affect the long-term results of operations, our financial position or our cash flows.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) requires management to make estimates and assumptions about future events, and apply judgments that affect the reported amounts of assets, liabilities, revenue and expenses in our consolidated financial statements and related notes. We base our estimates, assumptions and judgments on historical experience, current trends and other factors believed to be relevant at the time our consolidated financial statements are prepared. However, because future events and their effects cannot be determined with certainty, actual results could differ from our estimates and assumptions, and such differences could be material. We believe the following critical accounting policies affect our more significant estimates, assumptions and judgments used in the preparation of our consolidated financial statements.

Revenue Recognition – We recognize revenues from sales of products when the products are shipped and the title and risk of ownership pass to the customer. Final sales prices are fixed and 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.

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 which 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 do not provide us with a break-out of the amount of the total order price over the minimum sales price which includes the Representatives’ fee and Third Party Product amounts (“Due to Representatives”). The Due to Representatives amount is paid only after all amounts associated with the order are collected from the customer. The amount of payments to our Representatives was $57.1 million, $51.6 million and $51.4 million for the years ended December 31, 2012, 2011, and 2010, respectively.

Allowance for Doubtful Accounts - Our allowance for doubtful accounts is estimated to cover the risk of loss related to accounts receivable. We establish an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends in collections and write-offs, current customer status, the age of the receivable, economic conditions and other information. Aged receivables are reviewed on a monthly basis to determine if the reserve is adequate and adjusted accordingly at that time. The evaluation of these factors involves subjective judgments. Thus, changes in these factors or changes in economic circumstances may significantly impact our Consolidated Financial Statements.

Inventory Reserves – We establish a reserve for inventories based on the change in inventory requirements due to product line changes, the feasibility of using obsolete parts for upgraded part substitutions, the required parts needed for part supply sales, replacement parts and for estimated shrinkage.

Warranty – A provision is made for estimated warranty costs at the time the product is shipped and revenue is recognized. The warranty period is: the earlier of one year from the date of first use or 18 months from date of shipment for parts only; an additional four years on compressors (if applicable); 15 years on aluminized steel gas-fired heat exchangers (if applicable); 25 years on stainless steel heat exchangers (if applicable); and 10 years on gas-fired heat exchangers in RL products (if applicable). With the introduction of the RQ product line in 2010, our warranty policy for the RQ series was implemented to cover parts for two years from date of unit shipment and labor for one year from date of unit shipment. Warranty expense is estimated based on the warranty period, historical warranty trends and associated costs, and any known identifiable warranty issue.

Due to the absence of warranty history on new products, an additional provision may be made for such products. Our estimated future warranty cost is subject to adjustment from time to time depending on changes in actual warranty trends and cost experience. Should actual claim rates differ from our estimates, revisions to the estimated product warranty liability would be required.

Medical Insurance – A provision is made for medical costs associated with our Medical Employee Benefit Plan, which is primarily a self-funded plan. A provision is made for estimated medical costs based on historical claims paid and potential significant future claims. The plan is supplemented by employee contributions and any claim over $125,000 is covered by insurance.

Stock Compensation – We measure and recognize compensation expense for all share-based payment awards made to our employees and directors, including stock options and restricted stock awards, based on their fair values at the time of grant. Compensation expense, net of estimated forfeitures, is recognized on a straight-line basis during the service period of the related share-based compensation award. Forfeitures are estimated based on the Company's historical experience. The fair value of each option award and restricted stock award is estimated on the date of grant using the Black-Scholes-Merton option pricing model. The use of the Black-Scholes option valuation model requires the input of subjective assumptions such as: the expected volatility, the expected term of the options granted, expected dividend yield, and the risk free rate.

New Accounting Pronouncements

In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income and the update to this standard was issued December 2011. This standard eliminates the option to report other comprehensive income and its components in the statement of changes in equity. The amendment requires that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement should present total net income and its components followed consecutively by a second statement that should present total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. The amendment must be applied retrospectively and is effective for fiscal years and interim periods within those years, beginning after December 15, 2011. The adoption of this standard did not have a material effect on our consolidated financial statements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

We experience various market risks, primarily from commodity prices and interest rates. We do not use derivative financial instruments to hedge our interest rate risk. However, occasionally we use financial derivatives to economically hedge our commodity price risk. We do not use financial derivatives for speculative purposes.

Interest Rate Risk

We are exposed to interest rate risk on our revolving credit facility, which bears a variable interest rate of LIBOR plus 2.5%. At December 31, 2012 we had no borrowings outstanding under the revolving credit facility. The weighted average interest rate was 2.8% and 3.4% for the years ended December 31, 2012 and 2011, respectively.

Commodity Price Risk

We are exposed to volatility in the prices of commodities used in some of our products and occasionally we use fixed price cancellable and non-cancellable contracts with our major suppliers for periods of 6 to 18 months to manage this exposure. From time to time we use financial derivatives to economically hedge our commodity price risk. We do not have committed commodity derivative instruments in place at December 31, 2012.

Item 9A. Controls and Procedures.

(a) Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Annual Report on Form 10-K (the Evaluation Date), we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer with the oversight of the Audit Committee, regarding the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded, as of the end of the period covered by this Annual Report, that our disclosure controls and procedures were not effective as a result of the identified material weakness in internal control over financial reporting, the nature of which is summarized below.

(b) Management's Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting is a process 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.

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

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2012 based on the criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the results of this evaluation, we concluded that our internal control over financial reporting was not effective as of December 31, 2012 due to a material weakness in the review procedures associated with key financial statement elements related to intercompany activities, income taxes and inventory.

In light of the material weakness, the Company performed additional analysis and other post-closing procedures to ensure that the Company’s consolidated financial statements were prepared in accordance with generally accepted accounting principles and accurately reflect the results for the year ended December 31, 2012. As a result, notwithstanding the material weakness as described above, management concluded that the consolidated financial statements included in this Form 10-K present fairly in all material respects, the Company’s financial position, results of operations and cash flows for the periods presented.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2012 has been audited by Grant Thornton LLP, our independent registered public accounting firm, as stated in their report which is included in this Item 9A of this report on Form 10-K.

To remediate the material weakness described above and improve the operational effectiveness of our internal control over financial reporting, management is in the process of implementing the following items:

·	Hire a new Chief Accounting Officer with requisite technical and financial reporting skills to help address the identified matters.

·	Create a better model for analyzing inventory variances and automating this process to help eliminate errors.

·	Verify the accuracy of reports and data used in critical calculations.

·	Design a process and controls to ensure a more precise review is performed for manual journal entries relating to critical calculations and estimates.

The Company began implementing these items in the fourth quarter of 2012. However, not all items have been implemented yet and some items will be implemented subsequent to the filing of this Form 10-K. The material weakness will be fully remediated when, in the opinion of management, the revised control processes have been operating for a sufficient period of time to provide reasonable assurance as to their effectiveness. The remediation and ultimate resolution of our material weakness will be reviewed by the Audit Committee of our Board of Directors.

(d) Changes in Internal Control over Financial Reporting

Except as discussed in item (c) above, there have been no changes in internal control over financial reporting that occurred during the fourth quarter of 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

AAON, Inc.

We have audited the internal control over financial reporting of AAON, Inc. (a Nevada corporation) and subsidiaries (the “Company”) as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). 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 Annual Report on Internal Control over Financial Reporting (“Management’s Report”). 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 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.

A material weakness is a deficiency, or combination of control deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management’s assessment:

·	As indicated in the accompanying Management’s Report, management has identified a material weakness in the review procedures associated with key financial statement elements related to intercompany activities, income taxes and inventory.

In our opinion, because of the effect of the material weakness described above on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements of the Company as of and for the year ended December 31, 2012. The material weakness identified above was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2012 consolidated financial statements, and this report does not affect our report dated March 14, 2013, which expressed an unqualified opinion on those financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

AAON, Inc.

We have audited the accompanying consolidated balance sheets of AAON, Inc. (a Nevada Corporation) and subsidiaries (the “Company”) as of December 31, 2012 and 2011, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2012. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements 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, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of AAON, Inc. and subsidiaries as of December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012, in conformity with accounting principles generally accepted in the United States of America.

We also have 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, 2012, based on criteria established in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 14, 2013, expressed an adverse opinion on the effectiveness of internal control over financial reporting.

AAON, Inc. and Subsidiaries

Notes to Consolidated Financial Statements

December 31, 2012

1. Business Description

AAON, Inc. is a Nevada corporation which was incorporated on August 18, 1987. Our operating subsidiaries include AAON, Inc., an Oklahoma corporation and AAON Coil Products, Inc., a Texas corporation. The Consolidated Financial Statements include our accounts and the accounts of our subsidiaries. Unless the context otherwise requires, references in this Annual Report to “AAON,” the “Company”, “we,” “us,” “our” or “ours” refer to AAON, Inc., and our subsidiaries.

We are engaged in the manufacture and sale of air conditioning and heating equipment consisting of rooftop units, chillers, air-handling units, make-up air units, heat recovery units, condensing units and coils.

2. Summary of Significant Accounting Policies

Principles of Consolidation

These financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Cash and Cash Equivalents

We consider all highly liquid temporary investments with original maturity dates of three months or less to be cash equivalents. Cash and cash equivalents consist of bank deposits and highly liquid, interest-bearing money market funds. The Company's cash and cash equivalents are held in a few financial institutions in amounts that exceed the insurance limits of the Federal Deposit Insurance Corporation. However, management believes that the Company's counterparty risks are minimal based on the reputation and history of the institutions selected.

Investments

Certificates of Deposit

We invested $6.5 million in certificates of deposit for the year ending December 31, 2012 with various maturities ranging from two months to two years. The certificates of deposit bear interest ranging from 0.3% to 0.85% per annum. We did not invest in any certificates of deposit in 2011.

Investments Held to Maturity

Our investments held to maturity are comprised of $10.9 million of corporate notes and bonds with various maturities ranging from two months to 25 months. The investments have moderate risk with S&P ratings ranging from A+ to BBB-. We did not invest in any investments held to maturity in 2011.

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 at December 31, 2012:

			Gross		Gross
	Amortized		Unrealized		Unrealized			Fair
	Cost		Gain		Loss			Value
Current assets:	(in thousands)
Investments held to maturity	$	2,832	$	-	$	(1	)	$	2,831
Non current assets:
Investments held to maturity		8,041		-		(9	)		8,032
Total	$	10,873	$	-	$	(10	)	$	10,863

We evaluate these investments for other-than-temporary impairments on a quarterly basis. We do not believe that any of the unrealized losses represent an other-than-temporary impairment.

Accounts and Notes Receivable

Accounts and notes receivable are stated at amounts due from customers, net of an allowance for doubtful accounts. We generally do not require that our customers provide collateral. The Company determines its allowance for doubtful accounts by considering a number of factors, including the credit risk of specific customers, the customer’s ability to pay current obligations, historical trends, economic and market conditions and the age of the receivable. Accounts are considered past due when the balance has been outstanding for greater than ninety days. Past due accounts are generally written-off against the allowance for doubtful accounts only after all collection attempts have been exhausted.

Concentration of Credit Risk

Our customers are concentrated primarily in the domestic commercial and industrial new construction and replacement markets. To date, our sales have been primarily to the domestic market, with foreign sales accounting for approximately 5% of revenues for the years ended December 31, 2012, 2011 and 2010. No customer accounted for 10% of our sales during 2012, 2011 or 2010. Other than one customer who placed an exceptionally large order with an invoice date of 12/27/12 and a payment date of 1/17/13, no customer accounted for more than 5% of our accounts receivable balance at December 31, 2012, 2011 or 2010.

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, receivables, accounts payable and accrued liabilities approximate fair value because of the short-term maturity of the items. The carrying amount of the Company's revolving line of credit, and other payables, approximate their fair values either due to their short term nature, the variable rates associated with the debt or based on current rates offered to the Company for debt with similar characteristics.

Inventories

Inventories are valued at the lower of cost or market using the first-in, first-out (“FIFO”) method. Cost in inventory includes purchased parts and materials, direct labor and applied manufacturing overhead. 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.

Property, Plant and Equipment

Property, plant and equipment, including significant improvements, are recorded at cost, net of accumulated depreciation. Repairs and maintenance and any gains or losses on disposition are included in operations.

Depreciation is computed using the straight-line method over the following estimated useful lives:

Buildings	3-40 years
Machinery and equipment	3-15 years
Furniture and fixtures	3-7 years

Impairment of Long-Lived Assets

We review long-lived assets for possible impairment when events or changes in circumstances indicate, in management’s judgment, that the carrying amount of an asset may not be recoverable. Recoverability is measured by a comparison of the carrying amount of an asset or asset group to its estimated undiscounted future cash flows expected to be generated by the asset or asset group. If the undiscounted cash flows are less than the carrying amount of the asset or asset group, an impairment loss is recognized for the amount by which the carrying amount of the asset or asset group exceeds its fair value.

Research and Development

The costs associated with research and development for the purpose of developing and improving new products are expensed as incurred. For the years ended December 31, 2012, 2011, and 2010 research and development costs amounted to approximately $3.6 million, $4.8 million, and $3.6 million, respectively.

Advertising

Advertising costs are expensed as incurred. Advertising expense for the years ended December 31, 2012, 2011, and 2010 was approximately $0.9 million, $1.2 million, and $0.9 million, respectively.

Shipping and Handling

We incur shipping and handling costs in the distribution of products sold that are recorded in cost of sales. Shipping charges that are billed to the customer are recorded in revenues and as an expense in cost of sales. For the years ended December 31, 2012, 2011 and 2010 shipping and handling fees amounted to approximately $8.6 million, $8.7 million, and $8.6 million, respectively.

Income Taxes

Income taxes are accounted for under the asset and liability method. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the book carrying amounts and the tax basis of assets and liabilities. We establish accruals for uncertain tax positions when it is more likely than not that our tax return positions may not be fully sustained. The Company records a valuation allowance for deferred tax assets when, in the opinion of management, it is more likely than not that deferred tax assets will not be realized.

Stock Compensation

The Company recognizes expense for its share-based compensation based on the fair value of the awards that are granted. The Company’s share-based compensation plans provide for the granting of stock options, and restricted stock. The fair values of stock options are estimated at the date of grant using the Black-Scholes option valuation model. The use of the Black-Scholes option valuation model requires the input of subjective assumptions. Measured compensation cost, net of estimated forfeitures, is recognized ratably over the vesting period of the related share-based compensation award. Forfeitures are estimated based on the Company's historical experience. The fair value of restricted stock awards is determined based on the market value of the Company’s shares on the grant date and the compensation expense is recognized on a straight-line basis during the service period of the respective grant.

Financial Derivatives

The Company occasionally uses derivative financial instruments to reduce its exposure to the risk of increasing commodity prices. Contract terms of the hedging instrument closely mirror those of the hedged forecasted transaction providing for the hedge relationship to be highly effective both at inception and continuously throughout the term of the hedging relationship. The Company does not engage in speculative transactions, nor does the Company hold or issue financial instruments for trading purposes.

The Company recognizes all derivatives on the balance sheets at fair value. Derivatives that do not meet the criteria for hedge accounting are adjusted to fair value through income. If the derivative is designated as a cash flow hedge, changes in the fair value are recognized in accumulated other comprehensive income (loss) until the hedged transaction is recognized in income. If a hedging instrument is terminated, any unrealized gain (loss) at the date of termination is carried in accumulated other comprehensive income (loss) until the hedged transaction is recognized in income. The ineffective portion of a derivative’s change in fair value is recognized in income in the period of change.

Revenue Recognition

We recognize revenues from sales of products when the products are shipped and the title and risk of ownership pass to the customer. Final sales prices are fixed and 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.

The Representatives do not provide us with a break-out of the amount of the total order price over the minimum sales price which includes the Representatives’ fee and Third Party Product amounts (“Due to Representatives”). The Due to Representatives amount is paid only after all amounts associated with the order are collected from the customer. The amount of payments to our representatives was $57.1 million, $51.6 million, and $51.4 million for each of the years ended December 31, 2012, 2011, and 2010, respectively.

Insurance Reserves

Under the Company’s insurance programs, coverage is obtained for significant liability limits as well as those risks required to be insured by law or contract. It is the policy of the Company to self-insure a portion of certain expected losses related primarily to workers’ compensation and medical liability. Provisions for losses expected under these programs are recorded based on the Company’s estimates of the aggregate liabilities for the claims incurred.

Product Warranties

A provision is made for the estimated cost of maintaining product warranties to customers at the time the product is sold based upon historical claims experience by product line. The Company records a liability and an expense for estimated future warranty claims based upon historical experience and management's estimate of the level of future claims. Changes in the estimated amounts recognized in prior years are recorded as an adjustment to the liability and expense in the current year.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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, future 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 on a monthly basis. The most significant estimates include the allowance for doubtful accounts, inventory reserves, warranty accrual, workers compensation accrual, medical insurance accrual, share-based compensation and the fair value of derivative financial instruments. Actual results could differ materially from those estimates.

In connection with the closure of our Canadian facility on May 18, 2009 we sold land and a building in September 2010 and assumed a note receivable from the borrower secured by the property. The $1.1 million, fifteen-year note has an interest rate of 4.0% and is payable to us monthly, and has a $0.6 million balloon payment due in October 2025. Interest payments are recognized in interest income.

We evaluate the note for impairment on a quarterly basis. We determine the note receivable to be impaired if we are uncertain of its collectability based on the contractual terms. At December 31, 2012 and 2011 there was no impairment.

9. Revolving Credit Facility

Our revolving credit facility provides for maximum borrowings of $30.0 million which is provided by the Bank of Oklahoma, National Association. Under the line of credit, there is one standby letter of credit totaling $0.9 million. Borrowings available under the revolving credit facility at December 31, 2012, were $29.1 million. Interest on borrowings is payable monthly at LIBOR plus 2.5%. No fees are associated with the unused portion of the committed amount. As of December 31, 2012, we had no balance outstanding under our revolving credit facility and $4.6 million was outstanding at December 31, 2011. At December 31, 2012 and 2011, the weighted average interest rate was 2.8% and 3.4%, respectively

At December 31, 2012, we were in compliance with our financial covenants. These covenants require that we meet certain parameters related to our tangible net worth, total liabilities to tangible net worth ratio and working capital. At December 31, 2012 our tangible net worth was $138.1 million, which meets the requirement of being at or above $95.0 million. Our total liabilities to tangible net worth ratio was 0.4 to 1.0, which meets the requirement of not being above 2 to 1. Our working capital was $51.9 million which meets the requirement of being at or above $40.0 million.

10. Income Taxes

The provision for income taxes consists of the following:

	Years Ending December 31,
	2012			2011			2010
	(in thousands)
Current	$	18,896		$	(2,595	)	$	11,357
Deferred		(2,028	)		10,122			(558	)
	$	16,868		$	7,527		$	10,799

The provision for income taxes differs from the amount computed by applying the statutory federal income tax rate before the provision for income taxes.

The reconciliation of the federal statutory income tax rate to the effective income tax rate is as follows:

	Years Ending December 31,
	2012			2011			2010
Federal statutory rate	35		%	35		%	35		%
State income taxes, net of federal benefit	5		%	4		%	4		%
Other	(2	)	%	(4	)	%	(6	)	%
	38		%	35		%	33		%

Other primarily relates to the domestic production activity credit, certain domestic credits and a change in rate applied to deferred taxes.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amount used for income tax purposes.

The significant components of the Company’s deferred tax assets and liabilities are as follows:

	December 31
	2012			2011
	(in thousands)
Net current deferred assets and (liabilities) relating to:
Valuation reserves	$	164		$	221
Warranty accrual		2,287			2,376
Other accruals		1,996			1,216
Other, net		46			710
	$	4,493		$	4,523

Net long-term deferred assets and (liabilities) relating to:
Depreciation	$	(16,659	)	$	(18,802	)
Share-based compensation		653			648
Other, net		274			364
	$	(15,732	)	$	(17,790	)

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 2010 through 2012, and to non-U.S. income tax examinations for the tax years of 2007 through 2010. In addition, we are subject to state and local income tax examinations for the tax years 2009 through 2012.

The Company evaluates uncertain tax positions for recognition and measurement in the consolidated financial statements. To recognize a tax position, the Company determines whether it is more likely than not that the tax positions will be sustained upon examination, including resolution of any related appeals or litigation, based on the technical merits of the position. A tax position that meets the more likely than not threshold is measured to determine the amount of benefit to be recognized in the consolidated financial statements. The amount of tax benefit recognized with respect to any tax position is measured as the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement. The Company had no uncertain tax positions that required recognition in the consolidated financial statements at December 31, 2012 and 2011. Any interest or penalties would be recognized as a component of income tax expense.

The year ended December 31, 2011 resulted in a net operating loss (NOL) of $4.6 million. The full amount of the NOL is expected to be utilized with the filing of the 2012 federal tax return.

On January 2, 2013 the American Taxpayer Relief Act (ATRA) of 2012 was signed into law. Some of the provisions were retroactive to January 1, 2012, including the extension of certain tax credits. The tax rate above reflects the tax law that was in place as of December 31, 2012. Had the ATRA had been enacted prior to January 1, 2013, our overall tax expense would have been approximately $0.53 million lower at an overall effective rate of 37%. This $0.53 million difference will be reflected as a reduction in expense in the first quarter of 2013.

11. Share-Based Compensation

We have historically maintained a stock option plan for key employees, directors and consultants (“the 1992 Plan”). The 1992 Plan provided for 6.6 million shares to be issued under the plan in the form of stock options. Under the terms of the plan, the exercise price of shares granted may not be less than 85% of the fair market value at the date of the grant. Options granted to directors prior to May 25, 2004, vest one year from the date of grant and are exercisable for nine years thereafter. Options granted to directors on or after May 25, 2004, vest one-third each year, commencing one year after the date of grant. All other options granted vest at a rate of 20% per year, commencing one year after date of grant, and are exercisable during years 2-10.

On May 22, 2007, our stockholders adopted a Long-Term Incentive Plan (“LTIP”) which provides an additional 1,125,000 shares that can be granted in the form of stock options, stock appreciation rights, restricted stock awards, performance units and performance awards. Since inception of the Plan, non-qualified stock options and restricted stock awards have been granted with the same vesting schedule as the previous plan. Under the LTIP, the exercise price of shares granted may not be less than 100% of the fair market value at the date of the grant.

The total pre-tax compensation cost related to unvested stock options not yet recognized as of December 31, 2012 is $2.4 million and is expected to be recognized over a weighted-average period of 2.4 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 December 31, 2012, 2011 and 2010 using a Black Scholes Model:

	2012			2011			2010
Director and Officers:
Expected dividend yield		1.22	%		N/A			1.53	%
Expected volatility		47.54	%		N/A			45.37	%
Risk-free interest rate		1.19	%		N/A			2.63	%
Expected life (in years)		7			N/A			7

Employees:
Expected dividend yield		1.22	%		1.19	%		1.53	%
Expected volatility		45.99	%		45.22	%		45.29	%
Risk-free interest rate		1.19	%		1.41	%		2.44	%
Expected life (in years)		8			8			8

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 total intrinsic value of options exercised during December 31, 2012, 2011 and 2010 was $4.0 million, $1.1 million and $2.4 million, respectively. The cash received from options exercised during December 31, 2012, 2011 and 2010 was $2.0 million, $0.5 million and $1.2 million, respectively. The impact of these cash receipts is included in financing activities in the accompanying Consolidated Statements of Cash Flows.

During 2007, the Compensation Committee of the Board of Directors authorized and issued restricted stock awards to directors and key employees. The restricted stock award program offers the opportunity to earn shares of AAON Common Stock over time, rather than options that give the right to purchase stock at a set price. Restricted stock awards granted to directors vest one-third each year. All other restricted stock awards vest at a rate of 20% per year. Restricted stock awards are grants that entitle the holder to shares of common stock subject to certain terms. The fair value of restricted stock awards is based on the fair market value of AAON 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 December 31, 2012, unrecognized compensation cost related to unvested restricted stock awards was approximately $0.837 million which is expected to be recognized over a weighted average period of 2.2 years.

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

				Weighted
				Average
				Grant date

12. Employee Benefits

Defined Contribution Plan - 401(k) - We sponsor a defined contribution plan (“the Plan”). Eligible employees may make contributions in accordance with the Plan and IRS guidelines. In addition to the traditional 401(k), effective July 2010, eligible employees were given the option of making an after-tax contribution to a Roth 401(k) or a combination of both. Effective May 30, 2005, the Plan was amended to provide for automatic enrollment and provided for an automatic increase to the deferral percentage at January 1st of each year and each year thereafter, unless the employee elects to decline the automatic increase and enrollment. Beginning with pay periods after May 30, 2005, the one year enrollment waiting period was waived.

Under the plan the Company contributes a specified percentage of each eligible employee’s compensation. In addition, the Company contributes 1.5% of eligible payroll to the 401(k) plan each year. We contribute in the form of cash and direct the investment to shares of AAON stock. Employees are 100% vested in salary deferral contributions and vest 20% per year at the end of years two through six of employment in employer matching contributions. For the year ended December 31, 2012, 2011 and 2010 we made matching contributions of $2.4 million, $2.2 million and $1.7 million, respectively. Administrative expenses remained consistent at approximately $0.1 million for the years ended 2012, 2011 and 2010, respectively.

Profit Sharing Bonus Plan - We maintain a discretionary profit sharing bonus plan under which 10% of pre-tax profit is paid to eligible employees on a quarterly basis in order to reward employee productivity. Eligible employees are regular full-time employees who are actively employed and working on the first day of the calendar quarter and remain continuously, actively employed and working through the 15th of the third month following the calendar quarter and who work at least 80% of the five and one-half month period. Profit sharing expense was $4.9 million, $2.4 million and $3.8 million for the years ended December 31, 2012, 2011 and 2010, respectively.

13. Shareholders’ Equity

Stockholder Rights Plan - During 1999, the Board of Directors adopted a Stockholder Rights Plan (the “Plan”), which was amended in 2002. Under the Plan, stockholders of record on March 1, 1999, received a dividend of one right per share of our Common Stock. Stock issued after March 1, 1999, contains a notation incorporating the rights. Each right entitles the holder to purchase one one-thousandth (1/1,000) of a share of Series A Preferred Stock at an exercise price of $90. The rights are traded with our Common Stock. The rights become exercisable after a person has acquired, or a tender offer is made for, 15% or more of our Common Stock. If either of these events occurs, upon exercise the holder (other than a holder owning more than 15% of the outstanding stock) will receive the number of shares of our Common Stock having a market value equal to two times the exercise price.

The rights may be redeemed by us for $0.001 per right until a person or group has acquired 15% of our Common Stock. The rights expired on August 20, 2012.

Stock Repurchase - On May 12, 2010, we completed a stock buyback program under a Board of Directors authorization dated November 6, 2007. As authorized we repurchased a total of 2.7 million shares under this program for an aggregate price of approximately $36.1 million, or an average price of $13.36 per share. We purchased these shares at current market prices.

On May 17, 2010, the Board authorized a new stock buyback program, targeting repurchases of up to approximately 5% (approximately 1.3 million shares) of our outstanding stock from time to time in open market transactions. Through June 28, 2010, we repurchased a total of approximately 0.718 million shares for an aggregate price of $11.5 million, or an average price of $16.04 per share. We purchased the shares at current market prices. No purchases were made for the years ended December 31, 2012 and 2011.

Dividends - At the discretion of the Board of Directors we pay semi-annual cash dividends. Board approval is required to determine the date of declaration and amount for each semi-annual dividend payment. The Board of Directors approved dividend payments of $0.12 per share related to the 3-for-2 stock split effective on June 13, 2011.

We paid cash dividends of $8.8 million, $5.9 million and $9.2 million in 2012, 2011 and 2010, respectively.

14. Commitments and Contingencies

We are party to several short-term, cancelable and occasionally non-cancelable, fixed price contracts with major suppliers for the purchase of raw material and component parts. We expect to receive delivery of raw materials for use in our manufacturing operations. These contracts are not accounted for as derivative instruments because they meet the normal purchase and normal sales exemption.

15. New Accounting Pronouncements

16. 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.

The following table sets forth the computation of basic and diluted earnings per share:

Higher component prices adversely affected both gross margins and profits in the fourth quarter of 2011. Also, the Company experienced the negative effect of manufacturing inefficiencies due to the introduction of new products and, quite significantly, a $1.8 million charge to earnings caused by our decision to replace approximately 50% of AAON’s heavily-used sheet metal equipment to benefit from a Federal law allowing 100% depreciation (for tax purposes) of qualified capital expenditures put in service in calendar year 2011 and to gain greatly improved manufacturing efficiencies in 2012 and beyond. The charge to earnings was caused by a pre-tax loss of $1.8 million on the trade in of the old equipment. The new equipment is state of the art and combines the latest advancements in automation and laser technology, in furtherance of our strategic vision to improve manufacturing efficiencies.

A number of additional one-time charges were incurred in the fourth quarter of 2011:

·	Inefficient sheet metal production due to the changing out of approximately 50% of our capacity in a short period of time in order to have our new equipment operable by the end of the year.

·	Numerous costs expensed during the change out of the equipment.

·	Inefficiencies in production due to lack of sheet metal parts in a timely fashion.

·	Costs associated with relocating three assembly lines and rearranging two other assembly lines.
