Company Overview

Watsco, Inc. was incorporated in Florida in 1956, and, together with its subsidiaries (collectively, “Watsco,” or “we”, “us” or “our”) is the largest distributor of air conditioning, heating and refrigeration equipment and related parts and supplies (“HVAC/R”) in the HVAC/R distribution industry in North America. At December 31, 2016, we operated from 565 locations in 37 U.S. States, Canada, Mexico and Puerto Rico with additional market coverage on an export basis to portions of Latin America and the Caribbean.

Revenues primarily consist of sales of air conditioning, heating and refrigeration equipment and related parts and supplies. Selling, general and administrative expenses primarily consist of selling expenses, the largest components of which are salaries, commissions and marketing expenses that are variable and correlate to changes in sales. Other significant selling, general and administrative expenses relate to the operation of warehouse facilities, including a fleet of trucks and forklifts and facility rent, which are payable mostly under non-cancelable operating leases.

Sales of residential central air conditioners, heating equipment and parts and supplies are seasonal. Furthermore, results of operations can be impacted favorably or unfavorably based on weather patterns, primarily during the Summer and Winter selling seasons. Demand related to the residential central air conditioning replacement market is typically highest in the second and third quarters, and demand for heating equipment is usually highest in the fourth quarter. Demand related to the new construction market is fairly consistent during the year, subject to weather and economic conditions, including their effect on the number of housing completions.

Joint Ventures with Carrier Corporation

In 2009, we formed a joint venture with Carrier Corporation (“Carrier”), which we refer to as Carrier Enterprise I, in which Carrier contributed 95 of its company-owned locations in 13 Sun Belt states and Puerto Rico and its export division in Miami, Florida, and we contributed 15 locations that distributed Carrier products. In July 2012, we exercised our option to acquire an additional 10% ownership interest in Carrier Enterprise I, which increased our ownership interest to 70%; and, on July 1, 2014, we exercised our last remaining option to acquire an additional 10% ownership interest in Carrier Enterprise I, which increased our controlling interest to 80%. Neither Watsco nor Carrier has any remaining options to purchase additional ownership interests in Carrier Enterprise I or any of our other joint ventures with Carrier, which are described below.

In 2011, we formed a second joint venture with Carrier and completed two additional transactions. In April 2011, Carrier contributed 28 of its company-owned locations in eight Northeast U.S. states, and we contributed 14 locations in the Northeast United States. In July 2011, we purchased Carrier’s distribution operations in Mexico, which included seven locations. Collectively, the Northeast locations and the Mexico operations are referred to as Carrier Enterprise II. On November 29, 2016, we purchased an additional 10% ownership interest in Carrier Enterprise II, and, on February 13, 2017, we again purchased an additional 10% ownership interest in Carrier Enterprise II, which together increased our controlling interest to 80%.

In 2012, we formed a third joint venture, which we refer to as Carrier Enterprise III, with UTC Canada Corporation, referred to as UTC Canada, an affiliate of Carrier. Carrier contributed 35 of its company-owned locations in Canada to Carrier Enterprise III. We have a 60% controlling interest in Carrier Enterprise III, and UTC Canada has a 40% non-controlling interest.

Critical Accounting Policies

Management’s discussion and analysis of financial condition and results of operations is based upon the consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting period. Actual results may differ from these estimates under different assumptions or conditions. At least quarterly, management reevaluates its judgments and estimates, which are based on historical experience, current trends and various other assumptions that are believed to be reasonable under the circumstances.

Our significant accounting policies are discussed in Note 1 to our audited consolidated financial statements included with this Annual Report on Form 10-K. Management believes that the following accounting policies include a higher degree of judgment and/or complexity and, thus, are considered to be critical accounting policies. Management has discussed the development and selection of critical accounting policies with the Audit Committee of the Board of Directors and the Audit Committee has reviewed the disclosures relating to them.

Allowance for Doubtful Accounts

An allowance for doubtful accounts is maintained for estimated losses resulting from the inability of customers to make required payments. We typically do not require our customers to provide collateral. Accounting for doubtful accounts contains uncertainty because management must use judgment to assess the collectability of these accounts. When preparing these estimates, management considers a number of factors, including the aging of a customer’s account, past transactions with customers, creditworthiness of specific customers, historical trends and other information. Our business is seasonal and our customers’ businesses are also seasonal. Sales are lowest during the first and fourth quarters and past due accounts receivable balances as a percentage of total trade receivables generally increase during these quarters. We review our accounts receivable reserve policy periodically, reflecting current risks, trends and changes in industry conditions.

The allowance for doubtful accounts was $6.2 million and $5.3 million at December 31, 2016 and 2015, respectively, an increase of $0.9 million. The increase from December 31, 2015 is primarily due to an increase in the over 90 day balances. Accounts receivable balances greater than 90 days past due as a percent of accounts receivable at December 31, 2016 increased to 1.6% compared to 1.4% at December 31, 2015 primarily due to one account in which our exposure is mitigated by credit insurance.

Although we believe the allowance for doubtful accounts is sufficient, a decline in economic conditions could lead to the deterioration in the financial condition of our customers, resulting in an impairment of their ability to make payments and additional allowances may be required that could materially impact our consolidated results of operations. We believe our exposure to customer credit risk is limited due to the large number of customers comprising our customer base and their dispersion across many different geographical regions. Additionally, we mitigate credit risk through credit insurance programs.

Inventory Valuation Reserves

Inventory valuation reserves are established in order to report inventories at the lower of weighted-average cost or market and the first-in, first-out method. As part of the valuation process, inventories are adjusted to reflect excess, slow-moving and damaged inventories at their estimated net realizable value. The valuation process for excess, slow-moving and damaged inventory contains uncertainty because management must make estimates and use judgment to determine the future salability of inventories. Inventory policies are reviewed periodically, reflecting current risks, trends and changes in industry conditions. A reserve for estimated inventory shrinkage is also maintained and reflects the results of cycle count programs and physical inventories. When preparing these estimates, management considers historical results, inventory levels and current operating trends.

Valuation of Goodwill and Indefinite Lived Intangible Assets

The recoverability of goodwill is evaluated at least annually and when events or changes in circumstances indicate that the carrying amount may not be recoverable. We have one reporting unit that is subject to goodwill impairment testing. In performing the goodwill impairment test, we use a two-step approach. The first step compares the reporting unit’s fair value to its carrying value. If the carrying value exceeds the fair value, a second step is performed to measure the amount of impairment loss, if any. The identification and measurement of goodwill impairment involves the estimation of the fair value of our reporting unit and contains uncertainty because management must use judgment in determining appropriate assumptions to be used in the measurement of fair value. On January 1, 2017, we performed our annual goodwill impairment test and determined that the estimated fair value of our reporting unit significantly exceeded its carrying value.

The recoverability of indefinite lived intangibles is also evaluated on an annual basis or more often if deemed necessary. Indefinite lived intangibles not subject to amortization are assessed for impairment by comparing the fair value of the intangible asset to its carrying amount to determine if a write-down to fair value is required. Our annual impairment tests did not result in any impairment of our indefinite lived intangibles.

The estimates of fair value of our reporting unit and indefinite lived intangibles are based on the best information available as of the date of the assessment and incorporates management’s assumptions about expected future cash flows and contemplates other valuation techniques. Future cash flows can be affected by changes in the industry, a declining economic environment or market conditions. There have been no events or circumstances from the date of our assessments that would have had an impact on this conclusion. The carrying amounts of goodwill and intangibles were $538.3 million and $538.8 million at December 31, 2016 and 2015, respectively. Although no impairment has been recorded to date, there can be no assurances that future impairments will not occur. An adjustment to the carrying value of goodwill and intangibles could materially impact the consolidated results of operations.

Self-Insurance Reserves

Self-insurance reserves are maintained relative to company-wide casualty insurance and health benefit programs. The level of exposure from catastrophic events is limited by the purchase of stop-loss and aggregate liability reinsurance coverage. When estimating the self-insurance liabilities and related reserves, management considers a number of factors, which include historical claims experience, demographic factors, severity factors and valuations provided by independent third-party actuaries. Management reviews its assumptions with its independent third-party actuaries to evaluate whether the self-insurance reserves are adequate. If actual claims or adverse development of loss reserves occur and exceed these estimates, additional reserves may be required. The estimation process contains uncertainty since management must use judgment to estimate the ultimate cost that will be incurred to settle reported claims and unreported claims for incidents incurred but not reported as of the balance sheet date. Reserves in the amounts of $3.0 million and $3.2 million at December 31, 2016 and 2015, respectively, were established related to such insurance programs.

Income Taxes

Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial reporting basis and the tax basis of assets and liabilities at enacted tax rates expected to be in effect when such amounts are recovered or settled. The use of estimates by management is required to determine income tax expense, deferred tax assets and any related valuation allowance and deferred tax liabilities. No valuation allowance was recorded at December 31, 2016 or 2015. The valuation allowance is based on estimates of future taxable income by jurisdiction in which the deferred tax assets will be recoverable. These estimates can be affected by a number of factors, including possible tax audits or general economic conditions or competitive pressures that could affect future taxable income. Although management believes that the estimates are reasonable, the deferred tax asset and any related valuation allowance will need to be adjusted if management’s estimates of future taxable income differ from actual taxable income. An adjustment to the deferred tax asset and any related valuation allowance could materially impact the consolidated results of operations.

New Accounting Standards

Refer to Note 1 to our audited consolidated financial statements included in this Annual Report on Form 10-K for a discussion of new accounting standards.

Note: Due to rounding, percentages may not add up to 100.

The following narratives reflect our additional 10% ownership interest in Carrier Enterprise II, which became effective on November 29, 2016 and our additional 10% ownership interest in Carrier Enterprise I, which became effective on July 1, 2014. We did not acquire any businesses during 2016, 2015 or 2014.

In the following narratives, computations and disclosure information referring to “same-store basis” exclude the effects of locations acquired or locations opened or closed during the immediately preceding 12 months unless they are within close geographical proximity to existing locations. At December 31, 2016 and 2015, 21 and 26 locations, respectively, were excluded from “same-store basis” information. The table below summarizes the changes in our locations for 2016 and 2015:

2016 Compared to 2015

Revenues

Revenues for 2016 increased $107.5 million, or 3%, to $4,220.7 million, including $1.4 million from locations opened during the preceding 12 months, offset by $18.4 million from locations closed. On a same-store basis, revenues increased $124.5 million, or 3%, as compared to 2015, reflecting a 3% increase in sales of HVAC equipment (66% of sales), which included a 4% increase in residential HVAC equipment and a 1% increase in commercial HVAC equipment, a 1% increase in sales of other HVAC products (29% of sales) and a 6% increase in sales of commercial refrigeration products (5% of sales). The increase in same-store revenues was primarily due to demand for the replacement of residential HVAC equipment.

Gross Profit

Gross profit for 2016 increased $27.2 million, or 3%, to $1,034.6 million, primarily as a result of increased revenues. Gross profit margin remained consistent at 24.5% in 2016 as compared to 2015.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for 2016 increased $18.3 million, or 3%, to $689.0 million, primarily due to increased revenues. Selling, general and administrative expenses as a percentage of revenues remained consistent at 16.3% in 2016 as compared to 2015. Selling, general and administrative expenses for 2016 included $3.3 million of additional costs related to ongoing technology initiatives, as compared to 2015. On a same-store basis, selling, general and administrative expenses increased 3% as compared to 2015.

Operating Income

Operating income for 2016 increased $8.9 million, or 3%, to $345.6 million. Operating margin remained consistent at 8.2% in 2016 as compared to 2015.

Interest Expense, Net

Interest expense, net, for 2016 decreased $1.8 million, or 33%, to $3.7 million, primarily as a result of a decrease in average outstanding borrowings, partially offset by a higher effective interest rate in 2016, in each case as compared to 2015.

Income Taxes

Income taxes increased to $105.9 million for 2016, as compared to $104.7 million for 2015 and are a composite of the income taxes attributable to our wholly owned operations and income taxes attributable to the Carrier joint ventures, which are primarily taxed as partnerships for income tax purposes. The effective income tax rates attributable to us were 36.0% and 37.0% in 2016 and 2015, respectively. The decrease was primarily due to a $2.9 million benefit from the adoption of new accounting guidance related to share-based payments in 2016. See Note 1 to our consolidated financial statements contained in this Annual Report on Form 10-K.

Net Income Attributable to Watsco, Inc.

Net income attributable to Watsco in 2016 increased $9.9 million, or 6%, to $182.8 million. The increase was primarily driven by higher revenues and by a reduction in the net income attributable to the non-controlling interest related to Carrier Enterprise II following our purchase of an additional 10% ownership interest in Carrier Enterprise II in November 2016.

2015 Compared to 2014

Revenues

Revenues for 2015 increased $168.7 million, or 4%, to $4,113.2 million, including $4.9 million from locations opened during the preceding 12 months, offset by $32.8 million from locations closed. On a same-store basis, revenues increased $196.6 million, or 5%, as compared to 2014, reflecting a 7% increase in sales of HVAC equipment (66% of sales), which included a 6% increase in residential HVAC equipment and an 8% increase in commercial HVAC equipment, a 2% increase in sales of other HVAC products (29% of sales) and a 2% increase in sales of commercial refrigeration products (5% of sales). The increase in same-store revenues was primarily due to strong demand for the replacement of residential and commercial HVAC equipment. Revenues from sales of residential HVAC equipment also benefited from an improved sales mix of higher-efficiency air conditioning and heating systems, which sell at higher unit prices.

Gross Profit

Gross profit for 2015 increased $51.0 million, or 5%, to $1,007.4 million, primarily as a result of increased revenues. Gross profit margin improved 30 basis-points to 24.5% in 2015 from 24.2% in 2014, primarily due to higher realized gross margins for non-HVAC equipment products.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for 2015 increased $20.0 million, or 3%, to $670.6 million, primarily due to increased revenues. Selling, general and administrative expenses as a percentage of revenues decreased to 16.3% for 2015 from 16.5% for 2014. The decrease in selling, general, and administrative expenses as a percentage of revenues was primarily due to improved leveraging of fixed operating costs as compared to 2014. Selling, general and administrative expenses included $7.1 million of additional costs for 2015 in excess of 2014 for ongoing technology initiatives. On a same-store basis, selling, general and administrative expenses increased 4% as compared to 2014.

Operating Income

Operating income for 2015 increased $31.0 million, or 10%, to $336.7 million. Operating margin improved 40 basis-points to 8.2% in 2015 from 7.8% in 2014. The increase was driven by higher revenues, expanded gross profit margin and reduced selling, general and administrative expenses as a percent of revenues, as discussed above.

Interest Expense, Net

Interest expense, net, for 2015 increased $0.3 million, or 7%, to $5.5 million, primarily as a result of an increase in average outstanding borrowings, partially offset by a lower effective interest rate in 2015, in each case as compared to 2014.

Income Taxes

Income taxes increased to $104.7 million for 2015, as compared to $91.8 million for 2014 and are a composite of the income taxes attributable to our wholly owned operations and income taxes attributable to the Carrier joint ventures, which are primarily taxed as partnerships for income tax purposes. The effective income tax rate attributable to us was 37.0% in both 2015 and 2014.

Net Income Attributable to Watsco, Inc.

Net income attributable to Watsco in 2015 increased $21.5 million, or 14%, to $172.9 million. The increase was primarily driven by higher revenues, expanded profit margins and reduced selling, general and administrative expenses as a percent of revenues, as discussed above, and by a reduction in the net income attributable to the non-controlling interest related to Carrier Enterprise I following our purchase of an additional 10% ownership interest in Carrier Enterprise I in July 2014.

Liquidity and Capital Resources

We assess our liquidity in terms of our ability to generate cash to execute our business strategy and fund operating and investing activities, taking into consideration the seasonal demand for HVAC/R products, which peaks in the months of May through August. Significant factors that could affect our liquidity include the following:

Sources and Uses of Cash

We rely on cash flows from operations and borrowing capacity under our revolving credit agreement to fund seasonal working capital needs and for other general corporate purposes, including dividend payments, if and as declared by our Board of Directors, capital expenditures, business acquisitions and development of our long-term operating and technology strategies.

As of December 31, 2016, we had $56.0 million of cash and cash equivalents, of which, $50.7 million was held by foreign subsidiaries. The repatriation of cash balances from our foreign subsidiaries could have adverse tax consequences or be subject to capital controls; however, those balances are generally available without legal restrictions to fund ordinary business operations. Refer to Note 7 to our consolidated financial statements included in this Annual Report on Form 10-K for a discussion of undistributed earnings of our foreign subsidiaries.

We believe that our operating cash flows, cash on hand and funds available for borrowing under our line of credit will be sufficient to meet our liquidity needs in the foreseeable future. However, there can be no assurance that our current sources of available funds will be sufficient to meet our cash requirements.

Our access to funds under our line of credit depends on the ability of the syndicate banks to meet their respective funding commitments. Disruptions in the credit and capital markets could adversely affect our ability to draw on our line of credit and may also adversely affect the determination of interest rates, particularly rates based on LIBOR, which is one of the base rates under our line of credit. Disruptions in the credit and capital markets could also result in increased borrowing costs and/or reduced borrowing capacity under our line of credit.

Working Capital

Working capital increased 2% to $925.3 million at December 31, 2016 from $911.0 million at December 31, 2015, primarily reflecting higher levels of accounts receivable commensurate with our increase in overall business volume.

The individual items contributing to cash flow changes for the years presented are detailed in the audited consolidated statements of cash flows contained in this Annual Report on Form 10-K.

Operating Activities

The increase in net cash provided by operating activities was primarily due to the timing of payments for accounts payable and other liabilities in 2016 as compared to 2015.

Investing Activities

The increase in net cash used in investing activities in 2016 as compared to 2015 was primarily due to the purchase of a corporate aircraft, which is replacing a previously leased aircraft, for $30.7 million in 2016 partially offset by the purchase of owned space for expansion of our corporate headquarters in 2015.

Financing Activities

The increase in net cash used in financing activities was primarily attributable to the purchase of an additional 10% ownership interest in Carrier Enterprise II for $42.9 million and an increase in dividends paid in 2016, partially offset by lower net repayments under our revolving credit agreement in 2016 as compared to 2015.

Revolving Credit Agreement

We maintain an unsecured, syndicated revolving credit agreement that provides for borrowings of up to $600.0 million. Borrowings are used to fund seasonal working capital needs and for other general corporate purposes, including acquisitions, dividends (if and as declared by our Board of Directors), capital expenditures, stock repurchases and issuances of letters of credit. The credit agreement matures on July 1, 2019. Included in the facility are a $90.0 million swingline subfacility, a letter of credit subfacility and a $75.0 million multicurrency borrowing sublimit. On January 24, 2017, we entered into an amendment to this credit agreement, which reduced the letter of credit subfacility from $50.0 million to $10.0 million and modified certain definitions.

Borrowings under the credit facility bear interest at either LIBOR-based rates plus a spread, which ranges from 87.5 to 250.0 basis-points (LIBOR plus 100.0 basis-points at December 31, 2016), depending on our ratio of total debt to EBITDA, or on rates based on the higher of the Prime rate or the Federal Funds Rate, in each case plus a spread which ranges from 0 to 150.0 basis-points (0 basis-points at December 31, 2016), depending on our ratio of total debt to EBITDA. We pay a variable commitment fee on the unused portion of the commitment under the revolving credit agreement, ranging from 12.5 to 35.0 basis-points (15.0 basis-points at December 31, 2016).

At December 31, 2016 and 2015, $235.3 million and $245.3 million were outstanding under the revolving credit agreement, respectively. The revolving credit agreement contains customary affirmative and negative covenants, including financial covenants with respect to consolidated leverage and interest coverage ratios, and other customary restrictions. We believe we were in compliance with all covenants at December 31, 2016.

Commercial obligations outstanding at December 31, 2016 under our revolving credit agreement consisted of borrowings totaling $235.3 million with revolving maturities of seven to eight days.

Off-Balance Sheet Arrangements

Refer to Note 12 to our audited consolidated financial statements, under the caption “Off-Balance Sheet Financial Instruments,” for a discussion of standby letters of credit and performance bonds for which we were contingently liable under at December 31, 2016. Such discussion is incorporated herein by reference.

Purchase of Additional Ownership Interest in Joint Venture

On November 29, 2016, we purchased an additional 10% ownership interest in Carrier Enterprise II for cash consideration of $42.9 million, and, on February 13, 2017, we purchased an additional 10% ownership interest in Carrier Enterprise II for cash consideration of $42.7 million, following which we have an 80% controlling interest in Carrier Enterprise II. The source of cash was borrowings under our revolving credit agreement.

Acquisitions

We continually evaluate potential acquisitions and/or joint ventures and routinely hold discussions with a number of acquisition candidates. Should suitable acquisition opportunities arise that would require additional financing, we believe our financial position and earnings history provide a sufficient basis for us to either obtain additional debt financing at competitive rates and on reasonable terms or raise capital through the issuance of equity securities.

Common Stock Dividends

We paid cash dividends of $3.60, $2.80 and $2.00 per share of Common stock and Class B common stock in 2016, 2015 and 2014, respectively. On January 3, 2017, our Board of Directors declared a regular quarterly cash dividend of $1.05 per share of Common and Class B common stock that was paid on January 31, 2017 to shareholders of record as of January 17, 2017. Future dividends and/or changes in dividend rates will be at the sole discretion of the Board of Directors and will depend upon such factors as cash flow generated by operations, profitability, financial condition, cash requirements, future prospects and other factors deemed relevant by our Board of Directors.

Company Share Repurchase Program

In September 1999, our Board of Directors authorized the repurchase, at management’s discretion, of up to 7,500,000 shares of common stock in the open market or via private transactions. Shares repurchased under the program are accounted for using the cost method and result in a reduction of shareholders’ equity. No shares were repurchased in 2016, 2015 or 2014. In aggregate, 6,370,913 shares of Common and Class B common stock have been repurchased at a cost of $114.4 million since the inception of the program. At December 31, 2016, there were 1,129,087 shares remaining authorized for repurchase under the program.

Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risks, including fluctuations in foreign currency exchange rates and interest rates. To manage certain of these exposures, we use derivative instruments, including forward contracts and swaps. We use derivative instruments as risk management tools and not for trading purposes.

Foreign Currency Exposure

We are exposed to cash flow and earnings fluctuations resulting from currency exchange rate variations. These exposures are transactional and translational in nature. The foreign currency exchange rates to which we are exposed are the Canadian dollar and Mexican peso. Revenues in these markets accounted for 6% and 3%, respectively, of our total revenues for 2016.

Our transactional exposure primarily relates to purchases by our Canadian operations in currencies other than their local currency. To mitigate the impact of currency exchange rate movements on these purchases, we use foreign currency forward contracts. By entering into these foreign currency forward contracts, we lock in exchange rates that would otherwise cause losses should the U.S. dollar strengthen and gains should the U.S. dollar weaken, in each case against the Canadian dollar. The total notional value of our foreign currency forward contracts as of December 31, 2016 was $37.9 million, and such contracts have varying terms expiring through September 2017.

We have exposure related to the translation of financial statements of our Canadian operations into U.S. dollars, our functional currency. Currently, we do not hold any derivative contracts that hedge our foreign currency translational exposure.

Historically, fluctuations in these exchange rates have not materially impacted our results of operations. Our exposure to currency rate fluctuations could be material in the future if these fluctuations become significant or if our Canadian and Mexican markets grow and represent a larger percentage of our total revenues.

See Note 13 to our audited consolidated financial statements included in this Annual Report on Form 10-K for further information on our derivative instruments.

Interest Rate Exposure

Our revolving credit facility exposes us to interest rate risk because borrowings thereunder accrue interest at one or more variable interest rates. Our interest rate risk management objectives are to limit the impact of interest rate changes on earnings and cash flows and to lower overall borrowing costs. To achieve these objectives, we have historically entered into interest rate swap agreements with financial institutions that have investment grade credit ratings, thereby minimizing credit risk associated with these instruments. We do not currently hold any such swap agreements or any other derivative contracts that hedge our interest rate exposure, but we may enter into such instruments in the future.

We have evaluated our exposure to interest rates based on the amount of variable debt outstanding under our revolving credit agreement at December 31, 2016, and determined that a 100 basis-point change in interest rates would result in an impact to income before taxes of approximately $2.4 million. See Note 6 to our audited consolidated financial statements included in this Annual Report on Form 10-K for further information about our debt.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Our internal control system was designed to provide reasonable assurance to our management and Board of Directors regarding the reliability of financial reporting and the preparation and fair presentation of our published consolidated financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective may not prevent or detect misstatements and can provide only reasonable assurance with respect to financial statement preparation and presentation.
