Debt [Abstract]
Debt	(7) Debt We have a loan agreement with a group of banks that was entered into in June 2011 to fund our acquisition of Wheeler Bros., Inc ("WBI") and provide working capital for our continuing operations. The loan agreement, which expires in June 2016, consists of a term loan facility and a revolving loan facility that also provides us with letters of credit. Financing costs associated with the loan inception of approximately $1.7 million were capitalized and are being amortized over the five-year life of the loan. The loan agreement replaced a predecessor loan agreement that also consisted of a term loan, revolving loan, and letters of credit. The fair value of our outstanding debt as of December 31, 2012 approximates its carrying value. The term loan requires quarterly installment payments. Our future term loan payments are: $23.4 million in 2013, $25 million in 2014, $34.3 million in 2015, and $9.4 million in 2016. The amount of term loan borrowings outstanding as of December 31, 2012 is approximately $92.2 million. The amount of term loan borrowings outstanding as of December 31, 2011 was approximately $110.9 million. The maximum amount of credit available to us from the banking group for revolving loans and letters of credit as of December 31, 2012 was $125 million. The loan agreement provides that we may elect to increase this maximum to $175 million. Under the loan agreement terms, we may borrow revolving loan amounts at any time and can repay the borrowings at any time without premium or penalty. We pay an unused commitment fee and fees on letters of credit that are issued. We had outstanding as of December 31, 2012, approximately $48 million in revolving loan borrowings and $1.3 million of letters of credit. We had outstanding as of December 31, 2011, approximately $53.3 million in revolving loan borrowings and $5 million of letters of credit. Total bank loan borrowed funds outstanding as of December 31, 2012, including term loan borrowings and revolving loan borrowings, were approximately $140.2 million. Total bank loan borrowed funds outstanding as of December 31, 2011 were $164.2 million. We pay interest on the term loan borrowings and revolving loan borrowings at LIBOR plus a base margin or at a base rate (typically the prime rate) plus a base margin. As of December 31, 2012, the LIBOR base margin is 2.00% and the base rate base margin is 0.25%. The base margins increase or decrease in increments as our Total Funded Debt/EBITDA Ratio increases or decreases. We have employed interest rate hedges on a portion of our outstanding borrowings. In July 2011, we purchased a three-year amortizing LIBOR interest rate swap on the term loan debt for a notional amount of $101 million. The swap amount amortizes as the term loan amortizes, with reductions in the swap amount occurring on the same dates and for approximately the same amounts as term loan repayments. With the swap in place, we paid an effective rate on the hedged term debt of 0.56% plus our base margin from July 2011 through June 2012, and we pay an effective rate of 1.615% plus our base margin from July 2012 through June 2014. The amount of swapped term loan debt outstanding as of December 31, 2012 is $72.8 million. In July 2011, we purchased a two-year LIBOR interest rate swap on the revolving loan debt for a notional amount of $40 million. The swap amount declined to $20 million in June 2012, and expires in June 2013. With the swap in place, we pay an effective rate on the hedged term debt of 0.7775% plus our base margin during the two years. After taking into account the impact of hedging instruments, as of December 31, 2012, interest rates on portions of our outstanding debt ranged from 2.21% to 3.62%, and the effective interest rate on our aggregate outstanding debt was 3.10%. Interest expense incurred on bank loan borrowings was approximately $5.2 million and $3.1 million during the years ended December 31, 2012 and 2011, respectively. The loan agreement contains collateral requirements that secure our assets, restrictive covenants, a limit on annual dividends, other affirmative and negative covenants, and subjects us to certain conditions and other limitations. Restrictive covenants include a maximum Total Funded Debt/EBITDA Ratio, which decreases over time, a minimum Fixed Charge Coverage Ratio, and a minimum Asset Coverage Ratio, which increases over time. We were in compliance with required ratios and other terms and conditions at December 31, 2012.
