[1] The Company maintains a rabbi trust that serves as an investment designed to offset its deferred compensation plan liability. The investment assets of the trust consist of company-owned life insurance policies for which the Company recognizes income or expense based upon changes in cash surrender value.

[2] The fair value of the interest rate swaps was obtained from external sources. The interest rate swaps were valued using observable inputs (e.g., LIBOR yield curves, credit spreads). Valuations of interest rate swaps may fluctuate considerably from period-to-period due to volatility in underlying interest rates, which are driven by market conditions and the duration of the instrument. Credit adjustments could have a significant impact on the valuations due to changes in credit ratings of the Company or its counterparties.

[3] Senior management and other highly compensated associates may defer a specified percentage of their compensation into a non-qualified deferred compensation plan. Changes in the value of the deferred compensation under this plan are recognized each period based on the fair value of the underlying measurement funds.

[4] As a result of acquisitions in 2013 and 2012, the Company recorded contingent consideration liabilities at fair value. These fair value measurements were based on significant inputs related to future sales volumes in the Crown Rug and Colormaster acquisitions and incremental growth in gross margins of selected products of the Company in the Robertex acquisition and thus represent Level 3 measurements. Accordingly, changes in management's judgments or estimations could result in additional charges or benefits, respectively, as appropriate.
