AAON, Inc., and Subsidiaries

Notes to the Consolidated Financial Statements

(Unaudited)

1. Basis of Presentation

The accompanying unaudited consolidated financial statements of AAON, Inc., a Nevada corporation, and our operating subsidiaries, all of which are wholly-owned, (collectively, the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the rules and regulations of the Securities and Exchange Commission (“SEC”). These financial statements have not been audited by the Company's independent registered public accounting firm, except that the consolidated balance sheet at December 31, 2013 is derived from audited consolidated financial statements. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The financial statements reflect all adjustments (all of which are of a normal recurring nature) which are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. Interim results are not necessarily indicative of the results that may be expected for a full year. Certain disclosures have been condensed in or omitted from these consolidated financial statements. The accompanying unaudited financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 . All intercompany balances and transactions have been eliminated in consolidation.

We are engaged in the manufacture and sale of air conditioning and heating equipment consisting of rooftop units, chillers, outdoor mechanical rooms, air handling units, makeup air units, energy recovery units, condensing units, commercial self-contained units and coils.

Use of Estimates

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

Accounting Policies

A comprehensive discussion of our critical accounting policies and management estimates is included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2013 . There have been no significant changes in our critical accounting policies.

2. Revenue Recognition

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

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

- 5 -

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

The Representatives’ fee and Third Party Products amounts (“Due to Representatives”) are paid only after all amounts associated with the order are collected from the customer. The amount of payments to our representatives were $11.9 million and $13.6 million for the three months ended March 31, 2014 and 2013 , respectively.

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

3. Investments

Certificates of Deposit – We held $9.3 million and $10.7 million in certificates of deposit at March 31, 2014 , and December 31, 2013 , respectively. At March 31, 2014 , the certificates of deposit bear interest ranging from 0.20% to 0.90% per annum and have various maturities ranging from less than one month to approximately 13 months .

Investments Held to Maturity – Our investments held to maturity are comprised of $23.8 million of corporate notes and bonds with original maturities ranging from less than one month to approximately 13 months . The investments have moderate risk with S&P ratings ranging from AA+ to BBB-.

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

The following summarizes the amortized cost and estimated fair value of our investments held to maturity as of March 31, 2014 and December 31, 2013 :



	Amortized Cost		Gross Unrealized Gain		Gross Unrealized (Loss)		Fair Value

9. Revolving Credit Facility

Our revolving credit facility provides for maximum borrowings of $30.0 million which is provided by BOKF, NA dba Bank of Oklahoma, formerly known as Bank of Oklahoma, N.A. ("Bank of Oklahoma"). Under the line of credit, there is one standby letter of credit totaling $0.8 million . Borrowings available under the revolving credit facility at March 31, 2014 , were $29.2 million . Interest on borrowings is payable monthly at LIBOR plus 2.5% . No fees are associated with the unused portion of the committed amount. We had no outstanding balance under the revolving credit facility at March 31, 2014 and December 31, 2013 . Our weighted average interest rate was 2.65% at March 31, 2014 and 2.70% at December 31, 2013 .

As of March 31, 2014 , 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 March 31, 2014 , our tangible net worth was $ 172.1 million and met the requirement of being at or above $95.0 million . Our total liabilities to tangible net worth ratio was 0.33 to 1, and met the requirement of not being above 2 to 1. Our working capital was $ 96.4 million and met the requirement of being at or above $40.0 million .

The revolving credit facility matures on July 27, 2014.

10. Income Taxes

Income tax expense for each of the three months ended March 31, 2014 and 2013 , was $4.5 million , or 31.3% of pre-tax income, and $1.2 million , or 14.6% of pre-tax income, respectively. The Company’s estimated 2014 effective tax rate at March 31, 2014 is 34.0% . This differs from the U.S. federal statutory rate of 35% due principally to items such as state and local income taxes, the federal domestic activities deduction and various other federal and state income tax credits. The Company's income tax expense for the three months ended March 31, 2014, was decreased by $0.7 million due to a change in method of accounting for state investment credits to recognize them as each annual portion of the credit becomes available for use on tax returns. The income tax provision for the three months ended March 31, 2013 reflects discrete benefits related to the Research and Development (“R&D”) Credit and the Indian Employment Credit. These federal credits were retroactively reinstated on January 2, 2013, with the enactment of the American Taxpayer Relief Act of 2012. The Company also had a change in estimate related to the recoverability of certain 2012 tax credits that was recorded in the first quarter of 2013, causing our effective tax rate to be reduced. This change in estimate was the result of additional and better information.

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 2011 to present, and to non-U.S. income tax examinations for the tax years of 2008 through 2011. In addition, we are subject to state and local income tax examinations for the tax years 2010 to present. The Company continues to evaluate its need to file returns in various state jurisdictions. Any interest or penalties would be recognized as a component of income tax expense.

11. Share-Based Compensation

As discussed in Note 13, the Company had a three-for-two stock split effective July 2, 2013. All share information herein has been updated to reflect the effect of this stock split.

We have historically maintained a stock option plan for key employees, directors and consultants (“the 1992 Plan”). The 1992 Plan provided for 9.9 million shares to be issued under the plan in the form of stock options. Under the terms of the 1992 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 1.7 million 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 LTIP, 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 March 31, 2014 is $2.2 million and is expected to be recognized over a weighted-average period of 2.0 years.

- 9 -

The following weighted average assumptions were used to determine the fair value of the stock options granted on the original grant date for expense recognition purposes for options granted during the three months ended March 31, 2014 and 2013 using a Black Scholes Model:



	Three months ended
	March 31, 2014		March 31, 2013
Director and Officers:
Expected dividend yield	N/A		N/A
Expected volatility	N/A		N/A
Risk-free interest rate	N/A		N/A
Expected life (in years)	N/A		N/A

Employees:
Expected dividend yield	2.00	%	1.00	%
Expected volatility	45.73	%	45.62	%
Risk-free interest rate	2.40	%	1.23	%
Expected life (in years)	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 following is a summary of stock options vested and exercisable as of March 31, 2014 :



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

Outstanding at March 31, 2014	892,528		$	10.91
Exercisable at March 31, 2014	391,618		$	8.44

The total intrinsic value of options exercised during the three months ended March 31, 2014 and 2013 was $0.7 million and $0.8 million , respectively. The cash received from options exercised during the three months ended March 31, 2014 and 2013 was $0.3 million and $0.4 million , respectively. The impact of these cash receipts is included in financing activities in the accompanying Consolidated Statements of Cash Flows.

Since 2007, as part of the LTIP, the Compensation Committee of the Board of Directors has authorized and issued restricted stock awards to directors and key employees. Restricted stock awards granted to directors vest one-third each year. All other restricted stock awards vest at a rate of 20% per year. The fair value of restricted stock awards is based on the fair market value of AAON 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 March 31, 2014 , unrecognized compensation cost related to unvested restricted stock awards was approximately $2.7 million , which is expected to be recognized over a weighted average period of 2.5 years.

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




Restricted stock	Shares		Weighted Average Grant Date Fair Value
Unvested at December 31, 2013	157,354		$	19.16
Granted	9,855		27.39

12. Earnings Per Share

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

13. Stockholders’ Equity

Stock Repurchase - On May 17, 2010, the Board authorized a stock buyback program, targeting repurchases of up to approximately 5% (approximately 2.0 million shares) of our outstanding stock from time to time in open market transactions. Since the inception of the program, we repurchased a total of approximately 1.1 million shares for an aggregate price of $11.5 million , or an average price of $10.69 per share. We purchased the shares at current market prices. No repurchases were made under the program for the three months ended March 31, 2014 or the year ended December 31, 2013 .

- 12 -

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 the Company. The maximum number of shares to be repurchased is contingent upon the number of shares sold by employees. Through March 31, 2014 , we repurchased approximately 3.1 million shares for an aggregate price of $33.2 million , or an average price of $10.55 per share. We purchased the shares at current market prices. For the three months ended March 31, 2014 and 2013 , we repurchased shares of approximately 0.1 million , respectively.

Periodically, the Company repurchases shares of AAON stock from certain of its directors and employees. The number of shares to be repurchased is contingent upon Board approval. Through March 31, 2014 , we repurchased approximately 1.2 million shares for an aggregate price of $13.2 million , or an average price of $11.22 per share. We purchased the shares at current market prices. For the three months ended March 31, 2014 and 2013 we repurchased approximately 0.03 million and zero shares, respectively, under this program.

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.

On May 21, 2013, the Board of Directors declared a three-for-two stock split of the Company's common stock to be paid in the form of a stock dividend on July 2, 2013. Stockholders of record at the close of business on June 13, 2013 received one additional share for every two shares they held as of that date. All share and per share information has been updated to reflect the effects of this stock split.

On May 21, 2013, the Board of Directors approved a semi-annual cash dividend of $ 0.10 per share, post split, to the holders of our outstanding Common Stock as of the close of business on June 13, 2013, the record date. Those dividends were paid on July 2, 2013.

At a meeting of the Board of Directors on November 6, 2013, the Board declared a regular semi-annual cash dividend of $ 0.10 per share. The dividends were payable to shareholders of record at the close of business on December 2, 2013, the record date, and were paid on December 23, 2013.

On May 2, 2014, the Board declared a regular semi-annual cash dividend of $ 0.13 per share. The dividends will be payable to stockholders of record at the close of business on June 12, 2014, the record date, and payable on July 1, 2014. No dividends were declared or paid during the three months ended March 31, 2014 and 2013 .

14. Commitments and Contingencies

We are subject to various claims and legal actions that arise in the ordinary course of business. We closely monitor these claims and legal actions and frequently consult with our legal counsel to determine whether they may, when resolved, have a material adverse effect on our financial position, results of operations, or cash flows and we accrue and/or disclose loss contingencies as appropriate.

We are party to short-term, cancelable and 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 derivatives instruments because they meet the normal purchases and sales exemption. At March 31, 2014, we had one material contractual purchase obligation for approximately $1.0 million that expires in December 2014.

15. Subsequent Events

In April 2014, the Company pledged to donate a combination of air handling units and cash, with a combined total value of $1.0 million , to the Tulsa Library Trust.

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

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the notes thereto, which are included in this report, and our audited consolidated financial statements and the notes thereto, which are included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 . This discussion contains or incorporates by reference “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are not historical facts, but rather are based on expectations, estimates, assumptions and projections about our industry, business and future financial results, based on information available at the time this report is filed with the SEC or, with respect to any document incorporated by reference, available at the time that such document was prepared. Our actual results could differ materially from the results contemplated by these forward-looking statements due to a number of factors, including those identified in the section entitled “Forward-Looking Statements” in this Item 2 of this Quarterly Report on Form 10-Q and in the section entitled “Risk Factors” in Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 . We do not assume any obligation to update or revise any forward-looking statements to reflect changed assumptions, the occurrence of anticipated or unanticipated events, new information or circumstances or otherwise, except as required by law.

Overview

We engineer, manufacture and market air-conditioning and heating equipment consisting of rooftop units, chillers, outdoor mechanical rooms, air handling units, makeup air units, energy recovery units, condensing units, commercial self-contained units and coils. These products are marketed and sold to retail, manufacturing, educational, lodging, supermarket, medical and other commercial industries. We market our products to all 50 states in the United States and certain provinces in Canada. Foreign sales were approximately $4.7 million of our total net sales for the three months just ended and $4.8 million of our sales during the same period of 2013 .

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

We sell our products to property owners and contractors through a network of manufacturers’ representatives and our internal sales force. The demand for our products is influenced by national and regional economic and demographic factors. The commercial and industrial new construction market is subject to cyclical fluctuations in that it is generally tied to housing starts, but has a lag factor of six to 18 months. Housing starts, in turn, are affected by such factors as interest rates, the state of the economy, population growth and the relative age of the population. When new construction is down, we emphasize the replacement market. The new construction market in 2013 and the first quarter of 2014 continued to be unpredictable and uneven. Thus, throughout the year, we emphasized promotion of the benefits of AAON equipment to property owners in the replacement market.

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

The price levels of our raw materials have remained relatively consistent the past few years, but the market continues to be volatile and unpredictable as a result of the uncertainty related to the U.S. economy and a weakening global economy. For the three months ended March 31, 2014 , the prices for copper, galvanized steel, stainless steel and aluminum decreased by approximately 4.3% , 4.2% , 12.3% , and 6.2% respectively, from the three months ended March 31, 2013 .

In 2011, we began using an all aluminum microchannel condenser coil on our small rooftop unit product line and, in 2013, we began using this condenser coil in our new large rooftop product line as well. The condenser coil is the outdoor coil of a conventional air conditioning system. We expect to be using this type of condenser coil throughout the complete rooftop unit product line by the end of 2014 . This will reduce our copper tube usage in this component of the product, however, copper will remain a high volume raw material because of its use throughout the equipment.

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 six to 18 months. We expect to receive delivery of raw materials from our fixed price contracts for use in our manufacturing operations.

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


•	We had $ 3.6 million of capital expenditures during the three months ended March 31, 2014 , an increase of $ 2.6 million as compared to the same period in 2013 .


•	Our working capital increased $19.2 million or 24.8% for the three months ended March 31, 2014 , as compared to working capital at December 31, 2013.

The Company’s estimated 2014 effective tax rate at March 31, 2014 is 34.0%. The Company's income tax expense for the three months ended March 31, 2014 was decreased by $0.7 million due to a change in method of accounting for state investment credits to recognize them as each annual portion of the credit becomes available for use on tax returns. The income tax provision for the three months ended March 31, 2013 reflects discrete benefits related to the Research and Development (“R&D”) Credit and the Indian Employment Credit. These federal credits were retroactively reinstated on January 2, 2013, with the enactment of the American Taxpayer Relief Act of 2012. The Company also had a change in estimate related to the recoverability of certain 2012 tax credits that was recorded in the first quarter of 2013, causing our effective tax rate to be reduced. This change in estimate was the result of additional and better information.

Liquidity and Capital Resources

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

- 16 -

Our cash and short-term investments increased $15.4 million from December 31, 2013 to March 31, 2014 and totaled $51.6 million at March 31, 2014; while long-term investments decreased $12.4 million during the first quarter of 2014 as compared to the same period a year ago, from $13.6 million to $1.2 million, respectively.

Under the line of credit, there was one standby letter of credit of $0.8 million as of March 31, 2014 . At March 31, 2014 , we have $29.2 million of borrowings available under the revolving credit facility. No fees are associated with the unused portion of the committed amount.

We had no outstanding balance under the revolving credit facility at March 31, 2014 and December 31, 2013 . Interest on borrowings is payable monthly at LIBOR plus 2.5%. Our weighted average interest rate was 2.65% at March 31, 2014 and 2.70% at December 31, 2013 .

At March 31, 2014 , 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 March 31, 2014 , our tangible net worth was $172.1 million , which meets the requirement of being at or above $95.0 million. Our total liabilities to tangible net worth ratio was 0.33 to 1.0 which meets the requirement of not being above 2 to 1. Our working capital was $96.4 million , which meets the requirement of being at or above $40.0 million.

The revolving credit facility matures on July 27, 2014. We expect to renew our line of credit in July 2014 on comparable terms as we do not anticipate a tightening of funds in the financial markets.

We repurchased shares of stock from our employees’ 401(k) savings investment plan; option exercises of our directors and officers; and vested restricted stock from employees, directors and officers in the amount of $3.0 million for 0.1 million shares and $1.1 million for 0.1 million shares during the three months ended March 31, 2014 and 2013 , respectively. We repurchased the shares at current market prices. Prior year share amounts have been adjusted for the three-for-two stock split effective July 2, 2013.

On May 2, 2014, the Board declared a regular semi-annual cash dividend of $0.13 per share. The dividends will be payable to stockholders of record at the close of business on June 12, 2014, the record date, and payable on July 1, 2014. No dividends were declared or paid during the three months ended March 31, 2014 and 2013 .

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 2014 and the foreseeable future.

Cash Flows Provided by Operating Activities

Changes in cash flows provided by operating activities were primarily a result of increased net sales in the first quarter of 2014 as compared to the comparable period in 2013 and the fourth quarter of 2013 as well as timing of cash receipts and payments.

Cash Flows Used in Investing Activities

Capital expenditures increased in the first quarter of 2014 as compared to the same period in 2013 and were primarily related to investments in additional land and manufacturing and production equipment to support our growth and improve efficiencies.

The capital expenditure program for 2014 is estimated to be approximately $13.0 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.

No investment purchases were made in the first quarter of 2014 and maturities of previously purchased investments increased as compared to prior periods. We may make additional investment purchases during the remainder of 2014. Investment purchase activity is primarily attributable to investment of excess cash flows from operations.

Cash Flows Used in Financing Activities

We continued to make stock buybacks in 2014; see Part II, Item 2 of this report.

Forward-Looking Statements

This Quarterly Report on Form 10-Q includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as “expects”, “anticipates”, “intends”, “plans”, “believes”, “seeks”, “estimates”, “will”, “should”, and variations of such words and similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions, which are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they are made. We undertake no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Important factors that could cause results to differ materially from those in the forward-looking statements include (1) the timing and extent of changes in raw material and component prices, (2) the effects of fluctuations in the commercial/industrial new construction market, (3) the timing and extent of changes in interest rates, as well as other competitive factors during the year, and (4) general economic, market or business conditions.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Commodity Price Risk

We are exposed to volatility in the prices of commodities used in some of our products and we use fixed price cancellable and non-cancellable contracts with our major suppliers for periods of six to 18 months to manage this exposure.
