GENERAL
GENERAL
	NOTE 1.GENERAL
	Basis of Presentation
	The accompanying unaudited consolidated financial statements include the results of operations, financial position and cash flows of US Ecology, Inc. and its wholly-owned subsidiaries. All significant intercompany balances have been eliminated.  Throughout these financial statements words such as “we,” “us,” “our,” “US Ecology” and the “Company” refer to US Ecology, Inc. and its subsidiaries.
	In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments necessary to present fairly, in all material respects, the results of the Company for the periods presented. These consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been omitted pursuant to the rules and regulations of the SEC. These consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. The results of operations and cash flows for the three months ended March 31, 2015 are not necessarily indicative of results to be expected for the entire fiscal year.
	The Company’s Consolidated Balance Sheet as of December 31, 2014 has been derived from the Company’s audited Consolidated Balance Sheet as of that date and has been revised for purchase price measurement period adjustments related to the acquisition of EQ as disclosed in Note 2. Business Combination.
	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 the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our financial statements. As it relates to estimates and assumptions in amortization rates and environmental obligations, significant engineering, operations and accounting judgments are required. We review these estimates and assumptions no less than annually. In many circumstances, the ultimate outcome of these estimates and assumptions will not be known for decades into the future. Actual results could differ materially from these estimates and assumptions due to changes in applicable regulations, changes in future operational plans and inherent imprecision associated with estimating environmental impacts far into the future.
	Restricted Cash and Investments
	Restricted cash and investments represent funds held in third-party managed trust accounts as collateral for our financial assurance obligations for post-closure activities at our non-operating facilities.  These funds are invested in fixed-income U.S. Treasury and government agency securities and money market accounts.  The balances are adjusted monthly to fair market value based on quoted prices in active markets for identical or similar assets.
	Recently Issued Accounting Pronouncements
	In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-03 Simplifying the Presentation of Debt Issuance Costs, which changes the presentation of debt issuance costs in the financial statements. Under the standard, debt issuance costs are presented in the balance sheet as a direct deduction from the related debt liability rather than as an asset. The guidance is effective for annual and interim reporting periods beginning after December 15, 2015. We do not believe the adoption of this update will have a material effect on our financial position and results of operations.
	In May 2014, the FASB issued ASU No. 2014-09 Revenue from Contracts with Customers, which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. At its April 1, 2015, meeting, the FASB agreed to propose a one-year deferral of the revenue recognition standard’s effective date for all entities. The FASB intends to issue an exposure draft in the near term with a 30-day comment period. The Company is currently assessing the potential impact of ASU No. 2014-09 on its consolidated financial statements.

BUSINESS COMBINATION
BUSINESS COMBINATION
	NOTE 2.BUSINESS COMBINATION
	On June 17, 2014, the Company acquired 100% of the outstanding shares of EQ Holdings, Inc. and its wholly-owned subsidiaries (collectively “EQ”).  EQ is a fully integrated environmental services company providing waste treatment and disposal, wastewater treatment, remediation, recycling, industrial cleaning and maintenance, transportation, total waste management, technical services, and emergency response services to a variety of industries and customers in North America. The total purchase price was $460.9 million, net of cash acquired, and was funded through a combination of cash on hand and borrowings under a new $415.0 million term loan.
	We have recognized the assets and liabilities of EQ based on our preliminary estimates of their acquisition date fair values. The preliminary purchase price allocations are subject to change as additional information becomes available concerning the fair value and tax basis of the assets acquired and liabilities assumed. Any adjustments to the purchase price allocations are made as soon as practicable but no later than one year from the acquisition date. The following table summarizes the consideration paid for EQ and the preliminary fair value estimates of assets acquired and liabilities assumed recognized at the acquisition date, with purchase price allocation adjustments since the preliminary purchase price allocation as previously disclosed as of December 31, 2014:
		Purchase Price Allocation
	$s in thousands	As Reported in			Adjustments			As Retrospectively
		Form 10-K						Adjusted
	Current assets	$	111,982		$	294		$	112,276

	Identifiable intangible assets	252,874			—			252,874
	Current liabilities	(57,585		)	(727		)	(58,312		)
	Other liabilities	(139,331		)	(3,674		)	(143,005		)
	Total identifiable net assets	269,483			(4,107		)	265,376
	Goodwill	197,163			4,107			201,270
	Total purchase price	$	466,646		$	—		$	466,646
	Purchase price allocation adjustments relate primarily to the receipt of additional information regarding the fair values of income taxes payable and receivable, deferred income taxes and residual goodwill.
	Goodwill of $201.3 million arising from the acquisition is the result of several factors. EQ has an assembled workforce that serves the U.S. industrial market utilizing state-of-the-art technology to treat a wide range of industrial and hazardous waste. The acquisition of EQ increases our geographic base providing a coast-to-coast presence and an expanded service platform to better serve key North American hazardous waste markets. In addition, the acquisition of EQ provides us with an opportunity to compete for additional waste clean-up project work; expand penetration with national accounts; improve and enhance transportation, logistics, and service offerings with existing customers and attract new customers. $134.9 million of the goodwill recognized was allocated to reporting units in our Environmental Services segment and $66.4 million of the goodwill recognized was allocated to reporting units in our Field & Industrial Services segment. None of the goodwill recognized is expected to be deductible for income tax purposes.
	The preliminary fair value estimate of identifiable intangible assets by major intangible asset class and related weighted average amortization period are as follows:
	$s in thousands	Fair Value			Weighted Average
					Amortization Period
					(Years)
	Customer relationships	$	98,400		15

	Total identifiable intangible assets	$	252,874
	The following unaudited pro forma financial information presents the combined results of operations as if EQ had been combined with us at the beginning of each of the periods presented. The pro forma financial information includes the accounting effects of the business combination, including the amortization of intangible assets, depreciation of property, plant and equipment, and interest expense.  The unaudited pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of the periods presented, nor should it be taken as indication of our future consolidated results of operations.

	No customer accounted for more than 10% of total revenue for the three months ended March 31, 2015. Revenue from a single customer accounted for approximately 11% of total revenue for the three months ended March 31, 2014. No customer accounted for more than 10% of total trade receivables as of March 31, 2015 or December 31, 2014.
	Credit Risk Concentration
	We maintain most of our cash and cash equivalents with nationally recognized financial institutions like Wells Fargo Bank, National Association (“Wells Fargo”) and Comerica, Inc. Substantially all balances are uninsured and are not used as collateral for other obligations. Concentrations of credit risk on accounts receivable are believed to be limited due to the number, diversification and character of the obligors and our credit evaluation process.

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS
	NOTE 6.FAIR VALUE MEASUREMENTS
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  Assets and liabilities recorded at fair value are categorized using defined hierarchical levels directly related to the amount of subjectivity associated with the inputs to fair value measurements, as follows:
	Level 1 - Quoted prices in active markets for identical assets or liabilities;
	Level 2 - Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable;
	Level 3 - Unobservable inputs in which little or no market activity exists, requiring an entity to develop its own assumptions that market participants would use to value the asset or liability.
	The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, restricted cash and investments, accounts payable, accrued liabilities, debt and interest rate swap agreements. The estimated fair value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their carrying value due to the short-term nature of these instruments.
	The Company estimates the fair value of its variable-rate debt using Level 2 inputs, such as interest rates, related terms and maturities of similar obligations. The fair value of the Company’s debt approximated its carrying amount as of March 31, 2015.
	The Company’s assets and liabilities measured at fair value on a recurring basis consisted of the following:

	(1) We invest a portion of our Restricted cash and investments in fixed-income securities, including U.S. Treasury and U.S. agency securities. We measure the fair value of U.S. Treasury securities using quoted prices for identical assets in active markets. We measure the fair value of U.S. agency securities using observable market activity for similar assets. The fair value of our fixed-income securities approximates our cost basis in the investments.
	(2) We invest a portion of our Restricted cash and investments in money market funds. We measure the fair value of these money market fund investments using quoted prices for identical assets in active markets.
	(3) In order to manage interest rate exposure, we entered into an interest rate swap agreement in October 2014 that effectively converts a portion of our variable-rate debt to a fixed interest rate. The swap is designated as a cash flow hedge, with gains and losses deferred in other comprehensive income to be recognized as an adjustment to interest expense in the same period that the hedged interest payments affect earnings. The interest rate swap has an effective date of December 31, 2014 in an initial notional amount of $250.0 million. The fair value of the interest rate swap agreement represents the difference in the present value of cash flows calculated (i) at the contracted interest rates and (ii) at current market interest rates at the end of the period. We calculate the fair value of interest rate swap agreements quarterly based on the quoted market price for the same or similar financial instruments.  The fair value of the interest rate swap agreement is included in Other long-term liabilities in the Company’s consolidated balance sheet.

	Long-term debt	$	369,079		$	390,825
	On June 17, 2014, in connection with the acquisition of EQ, the Company entered into a new $540.0 million senior secured credit agreement (the “Credit Agreement”) with a syndicate of banks comprised of a $415.0 million term loan (the “Term Loan”) with a maturity date of June 17, 2021 and a $125.0 million revolving line of credit (the “Revolving Credit Facility”) with a maturity date of June 17, 2019. Upon entering into the Credit Agreement, the Company terminated its existing credit agreement with Wells Fargo, dated October, 29, 2010, as amended (the “Former Agreement”). Immediately prior to the termination of the Former Agreement, there were no outstanding borrowings under the Former Agreement.  No early termination penalties were incurred as a result of the termination of the Former Agreement.
	Term Loan
	The Term Loan provides an initial commitment amount of $415.0 million, the proceeds of which were used to acquire 100% of the outstanding shares of EQ and pay related transaction fees and expenses. The Term Loan bears interest at a base rate (as defined in the Credit Agreement) plus 2.00% or LIBOR plus 3.00%, at the Company’s option. The Term Loan is subject to amortization in equal quarterly installments in an aggregate annual amount equal to 1.00% of the original principal amount of the Term Loan. At March 31, 2015, the effective interest rate on the Term Loan was 3.75%. Interest only payments are due either monthly or on the last day of any interest period, as applicable. As set forth in the Credit Agreement, the Company is required to enter into one or more interest rate hedge agreements in amounts sufficient to fix the interest rate on at least 50% of the principal amount of the $415.0 million Term Loan.  In October 2014, the Company entered into an interest rate swap agreement with Wells Fargo, effectively fixing the interest rate on $250.0 million, or 67%, of the Term Loan principal outstanding as of March 31, 2015.
	Revolving Credit Facility
	The Revolving Credit Facility provides up to $125.0 million of revolving credit loans or letters of credit with the use of proceeds restricted solely for working capital and other general corporate purposes. Under the Revolving Credit Facility, revolving loans are available based on a base rate (as defined in the Credit Agreement) or LIBOR, at the Company’s option, plus an applicable margin which is determined according to a pricing grid under which the interest rate decreases or increases based on our ratio of funded debt to earnings before interest, taxes, depreciation and amortization (“EBITDA”). The Company is required to pay a commitment fee of 0.50% per annum on the unused portion of the Revolving Credit Facility, with such commitment fee to be reduced based upon the Company’s total leverage ratio as defined in the Credit Agreement.  The maximum letter of credit capacity under the new revolving credit facility is $50.0 million and the Credit Agreement provides for a letter of credit fee equal to the applicable margin for LIBOR loans under the Revolving Credit Facility. Interest only payments are due either monthly or on the last day of any interest period, as applicable. At March 31, 2015, there were no borrowings outstanding on the Revolving Credit Facility. The availability under the Revolving Credit Facility was $90.9 million with $34.1 million of the Revolving Credit Facility issued in the form of standby letters of credit utilized as collateral for closure and post-closure financial assurance and other assurance obligations.
	Except as set forth below, the Company may prepay the Term Loan or permanently reduce the Revolving Credit Facility commitment under the Credit Agreement at any time without premium or penalty (other than customary “breakage” costs with respect to the early termination of LIBOR loans).  On or prior to six months after the closing of the Credit Agreement, if we prepay the initial term loans or amend the pricing terms of the initial term loans, in each case in connection with a reduction of the effective yield, we are required to pay a 1% prepayment premium (unless in connection with a change of control, sale or permitted acquisition).  Subject to certain exceptions, the Credit Agreement provides for mandatory prepayment upon certain asset dispositions, casualty events and issuances of indebtedness.  The Credit Agreement is also subject to mandatory annual prepayments commencing in December 2015 if our total leverage (defined as the ratio of our consolidated funded debt as of the last day of the applicable fiscal year to our adjusted EBITDA for such period) exceeds certain ratios as follows: 50% of our adjusted excess cash flow (as defined in the Credit Agreement and which takes into account certain adjustments) if our total leverage ratio is greater than 2.50 to 1.00, with step-downs to 0% if our total leverage ratio is equal to or less than 2.50 to 1.00.
	Pursuant to (i) an unconditional guarantee agreement (the “Guarantee”) and (ii) a collateral agreement (the “Collateral Agreement”), each entered into by the Company and its domestic subsidiaries on June 17, 2014, the Company’s obligations under the Credit Agreement are jointly and severally and fully and unconditionally guaranteed on a senior basis by all of the Company’s existing and certain future domestic subsidiaries and the Credit Agreement is secured by substantially all of the Company’s and its domestic subsidiaries’ assets except the Company’s and its domestic subsidiaries’ real property.
	The Credit Agreement contains customary restrictive covenants, subject to certain permitted amounts and exceptions, including covenants limiting the ability of the Company to incur additional indebtedness, pay dividends and make other restricted payments, repurchase shares of our outstanding stock and create certain liens. We may only declare quarterly or annual dividends if on the date of declaration, no event of default has occurred and no other event or condition has occurred that would constitute default due to the payment of the dividend.
	The Credit Agreement also contains a financial maintenance covenant, which is a maximum Consolidated Senior Secured Leverage Ratio, as defined in the Credit Agreement, and is only applicable to the Revolving Credit Facility.  Our Consolidated Senior Secured Leverage Ratio as of the last day of any fiscal quarter, commencing with June 30, 2014, may not exceed the ratios indicated below:
	Fiscal Quarters Ending	Maximum Ratio
	June 30, 2014 through September 30, 2015	4.00 to 1.00
	December 31, 2015 through September 30, 2016	3.75 to 1.00
	December 31, 2016 through September 30, 2017	3.50 to 1.00
	December 31, 2017 through September 30, 2018	3.25 to 1.00
	December 31, 2018 and thereafter	3.00 to 1.00
	At March 31, 2015, we were in compliance with all of the financial covenants in the Credit Agreement.

The decrease for the three months ended March 31, 2015 primarily reflects a higher proportion of earnings from our Canadian operations, which are taxed at a lower corporate tax rate.
	We file a consolidated U.S. federal income tax return with the Internal Revenue Service as well as income tax returns in various states and Canada.

	NOTE 15.   OPERATING SEGMENTS
	Financial Information by Segment
	Subsequent to our acquisition of EQ on June 17, 2014, we made changes to the manner in which we manage our business, make operating decisions and assess our performance. Under our new structure our operations are managed in two reportable segments reflecting our internal reporting structure and nature of services offered as follows:
	Environmental Services - This segment includes all of the legacy US Ecology operations and the legacy EQ treatment and disposal facilities. It provides a broad range of hazardous material management services including transportation, recycling, treatment and disposal of hazardous and non-hazardous waste at Company-owned landfill, wastewater and other treatment facilities.
	Field & Industrial Services - This segment includes all of the field and industrial service business of the legacy EQ operation. It provides packaging and collection of hazardous waste and total waste management solutions at customer sites and through our 10-day transfer facilities.  Services include on-site management, waste characterization, transportation and disposal of non-hazardous and hazardous waste.  This segment also provides specialty services such as high-pressure and chemical cleaning, centrifuge and materials processing, tank cleaning, decontamination, remediation, transportation, spill cleanup and emergency response and other services to commercial and industrial facilities and to government entities.
	Prior to the acquisition of EQ, our operations were managed in two reportable segments: Operating Disposal Facilities and Non-Operating Disposal Facilities. The Operating Disposal Facility segment represented disposal facilities accepting hazardous and radioactive waste while the Non-Operating Disposal Facility segment represented facilities not accepting hazardous and/or radioactive waste or formerly proposed new facilities. All operations of both the former Operating Disposal Facilities and the Non-Operating Disposal Facilities segment are now included in the Environmental Services segment. None of the Company’s operations prior to the acquisition of EQ have been assigned to the Field & Industrial Services segment.
	The operations not managed through our two reportable segments are recorded as “Corporate.” Corporate selling, general and administrative expenses include typical corporate items such as legal, accounting and other items of a general corporate nature. Income taxes are assigned to Corporate, but all other items are included in the segment where they originated. Inter-company transactions have been eliminated from the segment information and are not significant between segments.
	Summarized financial information of our reportable segments is as follows:

	Total assets		$	155,149		$	—		$	145,007	$	300,156
	The primary financial measure used by management to assess segment performance is Adjusted EBITDA.  Adjusted EBITDA is defined as net income before net interest expense, income tax expense, depreciation, amortization, stock based compensation, accretion of closure and post-closure liabilities, foreign currency gain/loss and other income/expense, which are not considered part of usual business operations.  Adjusted EBITDA is a complement to results provided in accordance with accounting principles generally accepted in the United States (“GAAP”) and we believe that such information provides additional useful information to analysts, stockholders and other users to understand the Company’s operating performance. Since Adjusted EBITDA is not a measurement determined in accordance with GAAP and is thus susceptible to varying calculations, Adjusted EBITDA as presented may not be comparable to other similarly titled measures of other companies. Items excluded from Adjusted EBITDA are significant components in understanding and assessing our financial performance. Adjusted EBITDA should not be considered in isolation or as an alternative to, or substitute for, net income, cash flows generated by operations, investing or financing activities, or other financial statement data presented in the consolidated financial statements as indicators of financial performance or liquidity.  Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation or a substitute for analyzing our results as reported under GAAP.  Some of the limitations are:
		·		Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;
		·		Adjusted EBITDA does not reflect our interest expense, or the requirements necessary to service interest or principal payments on our debt;
		·		Adjusted EBITDA does not reflect our income tax expenses or the cash requirements to pay our taxes;
		·		Adjusted EBITDA does not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments; and
		·		Although depreciation and amortization charges are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements.

	The accompanying unaudited consolidated financial statements include the results of operations, financial position and cash flows of US Ecology, Inc. and its wholly-owned subsidiaries. All significant intercompany balances have been eliminated.  Throughout these financial statements words such as “we,” “us,” “our,” “US Ecology” and the “Company” refer to US Ecology, Inc. and its subsidiaries.
	In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments necessary to present fairly, in all material respects, the results of the Company for the periods presented. These consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been omitted pursuant to the rules and regulations of the SEC. These consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. The results of operations and cash flows for the three months ended March 31, 2015 are not necessarily indicative of results to be expected for the entire fiscal year.
	The Company’s Consolidated Balance Sheet as of December 31, 2014 has been derived from the Company’s audited Consolidated Balance Sheet as of that date and has been revised for purchase price measurement period adjustments related to the acquisition of EQ as disclosed in Note 2. Business Combination.
Use of Estimates
	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 the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our financial statements. As it relates to estimates and assumptions in amortization rates and environmental obligations, significant engineering, operations and accounting judgments are required. We review these estimates and assumptions no less than annually. In many circumstances, the ultimate outcome of these estimates and assumptions will not be known for decades into the future. Actual results could differ materially from these estimates and assumptions due to changes in applicable regulations, changes in future operational plans and inherent imprecision associated with estimating environmental impacts far into the future.
Restricted Cash and Investments
	Restricted Cash and Investments
	Restricted cash and investments represent funds held in third-party managed trust accounts as collateral for our financial assurance obligations for post-closure activities at our non-operating facilities.  These funds are invested in fixed-income U.S. Treasury and government agency securities and money market accounts.  The balances are adjusted monthly to fair market value based on quoted prices in active markets for identical or similar assets.
Recently Issued Accounting Pronouncements
	Recently Issued Accounting Pronouncements
	In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-03 Simplifying the Presentation of Debt Issuance Costs, which changes the presentation of debt issuance costs in the financial statements. Under the standard, debt issuance costs are presented in the balance sheet as a direct deduction from the related debt liability rather than as an asset. The guidance is effective for annual and interim reporting periods beginning after December 15, 2015. We do not believe the adoption of this update will have a material effect on our financial position and results of operations.
	In May 2014, the FASB issued ASU No. 2014-09 Revenue from Contracts with Customers, which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. At its April 1, 2015, meeting, the FASB agreed to propose a one-year deferral of the revenue recognition standard’s effective date for all entities. The FASB intends to issue an exposure draft in the near term with a 30-day comment period. The Company is currently assessing the potential impact of ASU No. 2014-09 on its consolidated financial statements.

	(1) We invest a portion of our Restricted cash and investments in fixed-income securities, including U.S. Treasury and U.S. agency securities. We measure the fair value of U.S. Treasury securities using quoted prices for identical assets in active markets. We measure the fair value of U.S. agency securities using observable market activity for similar assets. The fair value of our fixed-income securities approximates our cost basis in the investments.
	(2) We invest a portion of our Restricted cash and investments in money market funds. We measure the fair value of these money market fund investments using quoted prices for identical assets in active markets.
	(3) In order to manage interest rate exposure, we entered into an interest rate swap agreement in October 2014 that effectively converts a portion of our variable-rate debt to a fixed interest rate. The swap is designated as a cash flow hedge, with gains and losses deferred in other comprehensive income to be recognized as an adjustment to interest expense in the same period that the hedged interest payments affect earnings. The interest rate swap has an effective date of December 31, 2014 in an initial notional amount of $250.0 million. The fair value of the interest rate swap agreement represents the difference in the present value of cash flows calculated (i) at the contracted interest rates and (ii) at current market interest rates at the end of the period. We calculate the fair value of interest rate swap agreements quarterly based on the quoted market price for the same or similar financial instruments.  The fair value of the interest rate swap agreement is included in Other long-term liabilities in the Company’s consolidated balance sheet.
