We engineer, manufacture and market air-conditioning and heating equipment consisting of standardized and custom rooftop units, chillers, air-handling units, make-up units, heat recovery units, condensing units, coils and boilers. Custom units are marketed and sold to retail, manufacturing, educational, medical and other commercial industries. We market units to all 50 states in the United States and certain provinces in Canada. International sales are less than five percent as the majority of all sales are domestic.

We sell our products to property owners and contractors through a network of manufacturers' representatives and our internal sales force. 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 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. The raw materials market was volatile during 2009 and 2008 due to the economic environment. We attempt to limit the impact of price fluctuations on these materials by entering cancelable and noncancelable fixed price contracts with our major suppliers for periods of 6 - 18 months. We have entered into contracts that are both above and below the average index price as of June 30, 2009. Prices decreased by approximately 47% for steel, 74% for aluminum and 38% for copper from June 30, 2008 to June 30, 2009. The lower commodity prices have contributed to our lower cost of goods sold and higher gross profit.

Selling, general, and administrative ("SG&A") costs include our internal sales force, warranty costs, profit sharing and administrative expense. Warranty expense is estimated based on historical trends and other factors. Our product warranty is: the earlier of one year from the date of first use or 18 months from date of shipment for parts; an additional four years on compressors; 15 years on gas-fired heat exchangers; and 25 years on stainless steel heat exchangers. Warranty charges on heat exchangers occur infrequently.

Our office facilities consist of a 337,000 square foot building (322,000 sq. ft. of manufacturing/ warehouse space and 15,000 sq. ft. of office space) located at 2425 S. Yukon Avenue, Tulsa, Oklahoma ("the original facility"), and a 563,000 square foot manufacturing/warehouse building and a 22,000 square foot office building ("the expansion facility") located across the street from the original facility at 2440 S. Yukon Avenue. We previously leased 61% of the expansion facility to a third party. Upon expiration of the lease on May 31, 2009, we began renovations on the expansion facility to give us increased manufacturing capacity. Our 2009 capital expenditures budget reflects the projected outlay to remodel the facility.

Other operations are conducted in a plant/office building at 203-207 Gum Springs Road in Longview, Texas, containing 258,000 square feet (251,000 sq. ft. of manufacturing/ warehouse and 7,000 sq. ft. of office space). An additional 15 acres of land was purchased for future expansion in 2004 and 2005 in Longview, Texas.

Our operations in Burlington, Ontario, Canada, are located at 279 Sumach Drive, consisting of an 82,000 sq. ft. office/manufacturing facility on a 5.6 acre tract of land. The facility will be available for sale upon completion of our manufacturing operations in third quarter 2009. We have not yet contracted with a realtor; however we plan to sell the property within one year of the Canadian facility's closure.

Results of Operations

Key events impacting our cash balance, financial condition, and results of operations for the six months ended June 30, 2009, include the following:

o We remained the leader in the industry for environmentally-friendly, energy efficient and quality innovations, utilizing R410A refrigerant and phasing out pollutant causing R22 refrigerant. The phase out of R22 began in early 2004. We also utilize a high performance composite foam panel to eliminate over half of the heat transfer from typical fiberglass insulated panels. We continue to utilize sloped condenser coils, and access compartments to filters, motor, and fans. All of these innovations increase the demand for our products thus increasing market share.

o In February 2006, the Board of Directors initiated a program of semi-annual cash dividend payments. Cash dividend payments of $5.8 million were made in 2008 and $2.8 million in 2009. Cash dividends of $3.1 million were declared and accrued for in June 2009, and paid in July 2009. In May 2009, the Board of Directors increased the semi-annual cash dividend from $0.16 per share to $0.18 per share.

o Stock repurchases from employee's 401(k) savings and investments plan were authorized in 2005. Stock repurchases from directors and officers were authorized in 2006. Stock repurchases from the open market were authorized in 2007. Total purchases resulted in cash payments of $1.9 million for the first six months of 2009. The cash received in the six months ended June 30, 2009 from options exercised was $0.3 million.

o Purchases of equipment and expansion of facilities to create efficiencies remained a priority. Our capital expenditures were $5.8 million. Equipment purchases create significant efficiencies, lower production costs and allow continued growth in production. We currently expect to spend approximately $7.0 million to $8.0 million on capital expenditures during 2009 for continued growth. A portion of our budgeted capital expenditures will be spent expanding our manufacturing facilities in Tulsa. Such expansion provides manufacturing capacity to increase production of our products traditionally manufactured in Tulsa. The expansion also provides operational flexibility for us to establish production lines in Tulsa to manufacture custom products which are currently being manufactured at our Canadian facilities. We expect to close our Canadian facility in third quarter of 2009.

Net Sales

Net sales decreased $6.2 million or 8.3% to $68.6 million from $74.8 million for the three months ended, and decreased $7.6 million or 5.4% to $132.6 million from $140.2 million for the six months ended June 30, 2009, compared to the same periods in 2008. The decrease in net sales was a result of the current economic environment and lower sales from our Canadian operations.

Gross Profit

Gross profit increased $0.1 million or 0.6% to $18.1 million from $18.0 million for the three months ended, and increased $1.4 million or 4.2% to $35.0 million from $33.6 million for the six months ended June 30, 2009, compared to the same periods in 2008. As a percentage of sales, gross margins were 26.4% compared to 24.1% for the three months ended, and 26.4% compared to 24.0% for the six months ended June 30, 2009 and 2008, respectively. The increase in gross margins for the three months and six months was primarily a result of lower material costs and production and labor efficiencies which offset expenses related to the Canadian facility closure.

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. The raw materials market was volatile during 2009 and 2008 due to the economic environment. We attempt to limit the impact of price fluctuations on these materials by entering cancelable and noncancelable fixed price contracts with our major suppliers for periods of 6 - 18 months. We have entered into contracts that are both above and below the average index price as of June 30, 2009. Prices decreased by approximately 47% for steel, 74% for aluminum and 38% for copper from June 30, 2008 to June 30, 2009. The lower commodity prices have contributed to our lower cost of goods sold and higher gross profit.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $0.7 million or 11.5% to $6.8 million from $6.1 million for the three months ended, and increased $1.3 million or 10.8% to $13.3 million from $12.0 million for the six months ended June 30, 2009, compared to the same periods in 2008. The change was primarily due to an increase in warranty expense related to higher trade sales, bad debt expense to increase the bad debt reserve and sales related expenses.

Other Income (Expense)

Other expense increased approximately $188,000 to $71,000 compared to other income of approximately $117,000 for the three months ended June 30, 2009 and 2008, respectively. Other income decreased approximately $73,000 to $174,000 from $247,000 for the six months ended June 30, 2009, compared to the same periods in 2008. The increase in other expense was primarily related to foreign currency losses that resulted from operations in Canada in 2009 and 2008.

Other income is primarily attributable to rental income from our expansion facility which we received through the lease expiration on May 31, 2009. All expenses associated with the facility that are allocated to the rental portion of the building are included in other income. We previously leased 61% of the expansion facility to at third party. Upon expiration of the lease, we began renovations on the expansion facility to give us increased manufacturing capacity. Our 2009 capital expenditures budget reflects the projected outlay to remodel the facility.

Analysis of Liquidity and Capital Resources

Our working capital and capital expenditure requirements are generally met through net cash provided by operations and occasionally, based on current liquidity at the time, the revolving bank line of credit.

Our revolving credit facility provides for maximum borrowings of $15.2 million which is provided by the Bank of Oklahoma, National Association. Under the line of credit, there is one standby letter of credit totaling $1.0 million. The letter of credit was a requirement of our workers compensation insurance which has been renewed and will expire December 31, 2009. Interest on borrowings is payable monthly at the Wall Street Journal prime rate less 0.5% or LIBOR plus 1.6%, at our election (1.92% at June 30, 2009). No fees are associated with the unused portion of the committed amount.

At June 30, 2009, we did not have an outstanding balance under the revolving credit facility. At December 31, 2008, we had $2.9 million borrowed under the revolving credit facility. Borrowings available under the revolving credit facility at June 30, 2009 were $14.2 million. At June 30, 2009 and 2008, we were in compliance with our financial ratio covenants. The covenants are related to our tangible net worth, total liabilities to tangible net worth ratio and working capital. At June 30, 2009 our tangible net worth was $106.6 million. Our total liabilities to tangible net worth ratio was 2:5. Our working capital was $48.8 million. On July 30, 2009, we renewed the line of credit with a maturity date of July 30, 2010 with terms substantially consistent with the previous agreement.

Management believes our projected cash flows from operations and bank revolving credit facility, or comparable financing, will provide the necessary liquidity and capital resources for fiscal year 2009 and the foreseeable future. Our belief that we will have the necessary liquidity and capital resources is based upon our knowledge of the heating, ventilation, and air conditioning ("HVAC") industry and our place in that industry, our ability to limit the growth of our business if necessary, our ability to adjust dividend cash payments, and our relationship with the existing bank lender. For information concerning our revolving credit facility at June 30, 2009, see Note 6 to our Consolidated Financial Statements, Revolving Credit Facility.

Cash Flows Provided by Operating Activities. Net cash provided by operating activities increased in the six months ended June 30, 2009, by $9.9 million from the six months ended June 30, 2008. The increase was primarily due to changes in accounts receivable and provision for losses on accounts receivable, inventories, accrued liabilities and accounts receivable.

Cash Flows Used in Investing Activities. Cash flows used in investing activities were $5.8 million and $1.4 million for the six months ended June 30, 2009 and 2008, respectively. The increase in cash flows used in investing activities in 2009 was related to higher capital expenditures of $5.8 million for additions to machinery and equipment and manufacturing facilities, compared to $1.4 million for the same period in 2008. Capital expenditures in 2008 related to a building expansion and additions of machinery and equipment to further automate production. Management utilizes cash flows provided from operating activities to fund capital expenditures that are expected to increase growth and create efficiencies. We have budgeted capital expenditures of approximately $7.0 million to $8.0 million in 2009 to complete the building expansion that started in 2008, for our building renovation of the previously third party leased production facility, and for machinery and equipment purchases. We expect our cash requirements to be provided from cash flows from operations.

Cash Flows Used in Financing Activities. Cash flows used in financing activities were $7.1 million and $15.5 million for the six months ended June 30, 2009 and 2008, respectively. The decrease of cash used in financing activities is primarily due to fewer repurchases of our stock during the period.

We repurchased shares of stock from employees' 401(k) savings and investment plan, from directors and officers and the open market for the six months ended June 30, 2009 in the amount of $1.9 million for 100,358 shares of stock. There were shares of stock repurchased for a total of $17.3 million for the same period in 2008.

We received cash from stock options exercised of $0.3 million and classified the excess tax benefit of stock options exercised and restricted stock awards vested of $0.2 million in financing activities for the six months ended June 30, 2009. The cash received for options exercised and income tax effect partially offset the stock repurchase and dividend payments for the six months ended June 30, 2009. The cash received from stock options exercised for the same period in 2008 was $0.4 million and the excess tax benefit of stock options exercised and restricted stock awards vested was approximately $0.2 million.

Cash dividends were declared in December 2008 and were paid in January 2009 in the amount of $2.8 million. Cash dividends of $3.1 million were declared on May 19, 2009, and accrued then paid on July 2, 2009, to shareholders of record on June 11, 2009. Cash dividends of $2.8 million were declared on May 20, 2008, and accrued then paid on July 3, 2008 to shareholders of record on June 12, 2008. Board of Director approval is required to determine the date of declaration and amount for each semi-annual payment.

Critical Accounting Policies

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.

There have been no significant changes in critical accounting policies or management estimates since the year ended December 31, 2008. 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, 2008.

New Accounting Pronouncements

In December 2007, the FASB issued SFAS 141(R), Business Combinations ("SFAS 141R"), which replaced FASB Statement 141, Business Combinations. This statement significantly changed the accounting for business combinations and noncontrolling interests. Among other things, when compared to the predecessor guidance SFAS 141R requires (i) more assets acquired and liabilities assumed to be measured at fair value as of the acquisition date, (ii) liabilities related to contingent consideration to be remeasured to fair value each subsequent reporting period, and (iii) an acquirer in preacquisition periods to expense all acquisition-related costs. SFAS 141R must be applied prospectively for fiscal years beginning after December 15, 2008. Adoption of SFAS 141R did not have a material impact on our Consolidated Financial Statements.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements - an Amendment of ARB No. 51 ("SFAS 160"), which changes the accounting and reporting for minority interests, which will be recharacterized as noncontrolling interests and classified as a component of equity. SFAS 160 was required to be adopted no later than January 1, 2009. Adoption of SFAS 160 did not have a material impact on our Consolidated Financial Statements.

In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities--an Amendment of FASB Statement No. 133 ("SFAS 161"), which requires enhanced disclosures about (i) how and why an entity uses derivative instruments, (ii) how derivative instruments and related hedged items are accounted for under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended ("SFAS 133") and its related interpretations and (iii) how derivative instruments and related hedged items affect an entity's financial position, financial performance and cash flows. SFAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. Adoption of SFAS 161 did not have a material impact on our Consolidated Financial Statements.

In May 2009, the FASB issued SFAS No. 165, Subsequent Events ("SFAS 165"), which requires entities to disclose the date through which they have evaluated subsequent events and whether the date corresponds with the release of their financial statements. SFAS 165 is effective for interim and annual periods ending after June 15, 2009. Adoption of SFAS 165 did not have a material impact on our Consolidated Financial Statements.

In June 2009, the FASB issued SFAS No. 167, Amendments to FASB Interpretation No. 46 ("SFAS 167"), which alters how a company determines when an entity that is insufficiently capitalized or not controlled through voting should be consolidated. SFAS 167 will be effective for fiscal years beginning after November 15, 2009. We do not expect the adoption of SFAS 167 to have a material impact on our Consolidated Financial Statements.

In June 2009, the FASB issued SFAS No. 168, The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles ("SFAS 168"), which will supersede all accounting standards in U.S. GAAP, aside from those issued by the SEC. SFAS 168 will be effective for reporting periods ending after September 15, 2009.

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", 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.
