[1] The fair values of interest rate derivatives are the amount the company would receive or pay to terminate the contracts, considering quoted market prices of comparable agreements. (Also see Note 8)

[2] At June 30, 2013, a trade name originally determined to have an indefinite life was deemed to be impaired and an expense was recorded on a separate line in the Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2013. (Also see Note 5)

[3] The Monte Carlo simulation was used with a normal probability distribution of the best estimate of EBITDA for 2013 to approximate fair value. At June 30, 2013, the EBITDA target is not expected to occur and as such, the $7,950 of contingent consideration was deemed unlikely to be paid, and a benefit was recorded on a separate line in the Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2013.
