We have three outstanding unsecured senior note agreements with an aggregate amount outstanding of $227.1 million at December 31, 2012. These notes call for periodic principal payments with maturities that range from 2015 to 2021, of which $35.7 million is due in the next twelve months. Interest rates on these notes are fixed and range from 4.00% to 5.85%. The effective average interest rate on our outstanding senior note agreements was 5.07% and 5.17% at December 31, 2012 and 2011, respectively.

We have a five-year, $200.0 million senior unsecured revolving credit facility pursuant to the terms of a second amended and restated credit agreement on August 10, 2011 (the “Credit Agreement”), with Wells Fargo Bank, National Association (“Wells Fargo”) serving as administrative agent for the lenders. Of the $200.0 million line of credit commitments, $150.0 million may be used for letters of credit and $20.0 million may be used for borrowings under the Wells Fargo Sweep Plus Loan Program. This sweep program is a daily cash management tool that automatically initiates borrowings to cover overnight cash requirements up to an aggregate of $20.0 million. In addition, we have the right to request an increase in the line of credit commitments up to a total of $300.0 million in minimum increments of $25.0 million. At our option, revolving loans under the facility bear interest at either: (a) the Applicable Margin Percentage for Base Rate Loans plus the higher of Wells Fargo’s prime rate, the federal funds rate plus 0.5% per annum, or the one month LIBOR Rate plus 1.0% per annum; (b) the LIBOR Rate plus the Applicable Margin Percentage for LIBOR Loans; or (c) the LIBOR Market Index Rate (“LIBOR Index Rate”) plus the Applicable Margin Percentage for LIBOR Market Index Loans. The Applicable Margin Percentage is determined by a pricing grid in the Credit Agreement and ranges from 1.0% to 1.875%. The Applicable Margin Percentage was 1.125% at December 31, 2012 and 2011, respectively, and ranged from 1.0% to 1.125% during 2012. Revolving loans under the sweep program bear interest at the LIBOR Index Rate.

The outstanding balance of borrowings on the line of credit facility was $10.0 million and zero at December 31, 2012 and 2011, respectively. There were $52.4 million and $49.9 million of outstanding letters of credit at December 31, 2012 and 2011, respectively.

Commitment fees ranging from 0.175% to 0.30% are charged quarterly in arrears on the aggregate unutilized portion of the Credit Agreement. Letter of credit fees equal to the applicable margin for Adjusted LIBOR Rate loans are charged quarterly in arrears on the daily average aggregate stated amount of all letters of credit outstanding during the quarter. The commitment fees ranged from 0.175% to 0.20% and letter of credit fees ranged from 1.0% to 1.125% during 2012. In addition, the Company will pay to Wells Fargo as issuer of letters of credit (i) a facing fee with respect to each letter of credit in an amount equal to 0.125% of the daily average aggregate Stated Amount thereof, payable quarterly in arrears and calculated on an actual/360-day basis and (ii) such fees and charges customarily charged in connection with the issuance and administration of such letters of credit. Wells Fargo, as administrative agent, shall also receive an annual administrative fee for providing such services.

Our Credit Agreement limits the amount of dividends that could be paid to shareholders to the greater of (i) $20.0 million, (ii) the amount of dividends paid in the immediately preceding fiscal year, or (iii) an amount equal to 25% of net income from the immediately preceding fiscal year. We did not declare or pay a dividend on our common stock in 2012 or 2011, and we have no plans to declare or pay a dividend in 2013.

Our three outstanding senior note agreements and the Credit Agreement contain customary covenants, including financial covenants that require us to observe a maximum ratio of debt to total capital and a minimum fixed charge coverage ratio. Any future wholly-owned subsidiaries of the Company would be required to guarantee payment of all of our obligations under these agreements.

Capitalized lease obligations are collateralized by property and equipment with a net book value of $7.6 million at December 31, 2012.
