Line of Credit Facility, Interest Rate Description	Interest on loans outstanding under the New Credit Agreement is based, at our election, on a base rate, a Eurodollar Rate or an index rate, in each case plus an applicable margin. The base rate is the highest of (i) the rate which the Administrative Agent announces from time to time as its prime lending rate, (ii) the Federal Funds rate, as in effect from time to time, plus one-half of one percent ( 1/2%) per annum and (iii) the Eurodollar Rate determined on a daily basis for an Interest Period of one (1) month, plus one percent (1.00%) per annum. The Eurodollar Rate is the London interbank offered rate for deposits in U.S. Dollars for approximately a term comparable to the applicable interest period (one, two, three or six months, at our election), subject to adjustment for any applicable reserve percentages. The index rate is the rate equal to the offered rate for deposits in U.S. Dollars for a one (1) month interest period, as appears on the Bloomberg reporting service, or such similar service as determined by the Administrative Agent that displays British Bankers’ Association interest settlement rates for deposits in Dollars, subject to adjustment for any applicable reserve percentages. The applicable margin is based upon our leverage ratio, as defined in the New Credit Agreement, and ranges from 0.50% to 1.25% in the case of base rate loans and 1.50% to 2.25% in the case of index rate loans and Eurodollar loans.
Line of Credit Facility, Commitment Fee Description	We must also pay a commitment fee to the Administrative Agent for the account of each lender, which, based on our leverage ratio, accrues at a rate of 0.20% or 0.25% per annum on the daily amount of the unused portion of the revolving loan.
Debt Instrument, Periodic Payment, Principal First Year	375
Debt Instrument, Principal Payment Second Year until Maturity	750
Line of Credit Hedging Requirement	The New Credit Agreement requires that, within one-year after entering into the New Credit Agreement (or such later date as agreed to by the Administrative Agent), we fix or limit our interest exposure to at least fifty percent (50%) of the term loan pursuant to one or more hedging arrangements reasonably satisfactory to the Administrative Agent. On May 15, 2012, pursuant to the terms of the New Credit Agreement we entered into an interest rate swap agreement with the Administrative Agent as a cash flow hedge.

Line of Credit Facility, Covenant Terms	the New Credit Agreement contains financial covenants requiring that we maintain a leverage ratio of not greater than 2.50 to 1.00 and a fixed charge coverage ratio (as defined in the New Credit Agreement) of not less than 2.00 to 1.00.
