INCOME TAXES	'
	INCOME TAXES
	The Company’s income tax provision consists of federal, state and foreign income taxes.  The tax provisions for the three months ended March 31, 2014 and 2013 were based on the estimated effective tax rates applicable for the full years ending December 31, 2014 and 2013, after giving effect to items specifically related to the interim periods.  The Company’s effective tax rate was 35.3% for the three months ended March 31, 2014 and 39.8% for the three months ended March 31, 2013. The decrease in the Company's effective tax rate for the three months ended March 31, 2014, was primarily a result of the geographic mix of pretax income and the different tax rates of these jurisdictions.
	As of March 31, 2014 and December 31, 2013, the Company had unrecognized tax benefits of approximately $0.9 million and $0.8 million, respectively.  These unrecognized tax benefits amounts would affect the effective tax rate if recognized.  As of March 31, 2014, the Company is subject to U.S. Federal income tax examinations for the tax years 2010 through 2013, and to non-U.S. income tax examinations for the tax years 2005 through 2013.  In addition, the Company is subject to state and local income tax examinations for the tax years 2005 through 2013.

FAIR VALUE OF FINANCIAL INSTRUMENTS	'
	FAIR VALUE OF FINANCIAL INSTRUMENTS
	Fair value is 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. The Company uses the following valuation techniques to measure fair value for its financial assets and financial liabilities:
	·                  Level 1: Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
	·                  Level 2: Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.
	·                  Level 3: Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.
	The fair value of the Company's cash and cash equivalents, accounts receivable and accounts payable approximate carrying value due to their short maturities.
	The fair value of the Company’s long-term debt approximates its carrying value, as it is variable rate debt and the terms are comparable to market terms as of the balance sheet dates, and are classified as Level 2.

	Assets and Liabilities Recorded at Fair Value on a Recurring Basis
	The following table represents the financial assets and liabilities, measured at fair value on a recurring basis as of March 31, 2014 and the basis for that measurement (in thousands):

	Contingent purchase price payments related to the acquisition of HOLLY HUNT®	$	—	$	—	$	16,000	$	16,000
	Pursuant to the agreement governing the acquisition of HOLLY HUNT®, the Company may be required to make annual contingent purchase price payments for the next three years. The payouts are based upon HOLLY HUNT® reaching an annual net sales target, for each year over the next three calendar years, and are paid out by February 15 of the following calendar year. The Company classifies this as a Level 3 measurement and is required to remeasure this liability at fair value on a recurring basis. The fair value of such contingent purchase price payments was determined based upon net sales projections for HOLLY HUNT® for 2014, 2015, and 2016. Excluding the initial recognition of the liability for the contingent purchase price payments and payments made to reduce the liability, any changes in the fair value would be included within selling, general and administrative expenses.
	There were no assets and/or liabilities recorded at fair value on a recurring basis as of December 31, 2013.
	Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis
	The following table represents the financial assets and liabilities, measured at fair value on a nonrecurring basis as of December 31, 2013 and the basis for that measurement (in thousands):

	(1) The Company estimated the fair value of the indefinite-life intangible asset using the relief-from-royalty method under the income approach. The Company used a royalty rate of 5% based on comparable market rates and used a discount rate of 12.7%.
	In the fourth quarter of 2013, the Company completed the annual goodwill and indefinite-lived intangible assets impairment analysis and determined that the Edelman Leather Tradename was impaired. As a result, the carrying amount of the Edelman Leather Tradename was reduced from $26.1 million to $17.2 million, resulting in an impairment charge of $8.9 million. There were no assets or liabilities recorded at fair value on a nonrecurring basis as of March 31, 2014.

As a result of these actions, the Company recorded restructuring charges of $2.7 million in the Office segment and $3.0 million in the Studio segment during the fourth quarter of 2013.
