Debt	6 Months Ended
Jun. 24, 2012
Debt	5. Debt Our long-term debt is comprised of the outstanding balance under our revolving line of credit. The balance was $50.0 million as of June 24, 2012 and $51.5 million as of December 25, 2011. In September 2010, we entered into a five-year, $175.0 million unsecured revolving credit facility (“Credit Facility”). The Credit Facility was amended in November 2011 (the “Amended Credit Facility”), which extended the maturity date of the Credit Facility to November 30, 2016. Under the Amended Credit Facility, outstanding balances accrue interest at 75 basis points to 150 basis points over LIBOR or other bank developed rates at our option (previously interest accrued at 100 basis points to 175 basis points above LIBOR). The remaining availability under the Amended Credit Facility, reduced for outstanding letters of credit, was approximately $111.5 million as of June 24, 2012. The fair value of the outstanding debt approximates the carrying value since the debt agreements are variable-rate instruments. The Amended Credit Facility contains customary affirmative and negative covenants, including financial covenants requiring the maintenance of specified fixed charges and leverage ratios. At June 24, 2012, we were in compliance with these covenants. In August 2011, we entered into an interest rate swap agreement that provides for a fixed rate of 0.53%, as compared to LIBOR, with a notional amount of $50.0 million. The interest rate swap agreement expires in August 2013. We previously had two interest rate swap agreements that expired in January 2011. The previous swap agreements provided for fixed rates of 4.98% and 3.74%, as compared to LIBOR, with each having a notional amount of $50.0 million. Our swaps are derivative instruments that are designated as cash flow hedges because the swaps provide a hedge against the effects of rising interest rates on borrowings. The effective portion of the gain or loss on the swap is reported as a component of accumulated other comprehensive income and reclassified into earnings in the same period or periods during which the swap affects earnings. Gains or losses on the swap representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. Amounts payable or receivable under the swap are accounted for as adjustments to interest expense. As of June 24, 2012, the swap is a highly effective cash flow hedge. The weighted average interest rates for our revolving credit facilities, including the impact of the swap agreements, were 1.3% and 1.2% for the three months ended June 24, 2012 and June 26, 2011, respectively, and 1.3% and 2.4% for the six months ended June 24, 2012 and June 26, 2011, respectively. Interest paid, including payments made or received under the swaps, was $232,000 and $248,000 for the three months ended June 24, 2012 and June 26, 2011, respectively, and $482,000 and $1.1 million for the six months ended June 24, 2012 and June 26, 2011, respectively. As of June 24, 2012, the portion of the $127,000 interest rate swap liability that would be reclassified into earnings during the next twelve months as interest expense approximates $109,000.
