We have three outstanding unsecured senior note agreements with an aggregate amount outstanding of $155.7 million at December 31, 2014. 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 weighted average interest rate on our outstanding senior note agreements was 4.87% and 4.99% at December 31, 2014 and 2013, 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 dated August 10, 2011, as amended on November 7, 2014 (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. We utilize the sweep program to manage our daily cash needs, as the sweep program 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% based upon the ratio of debt to total capitalization. The Applicable Margin Percentage remained at 1.0% during 2014 and ranged from 1.0% to 1.125% during 2013. Revolving loans under the sweep program bear interest at the LIBOR Index Rate. There were $63.2 million and $57.7 million of outstanding letters of credit at December 31, 2014 and 2013, respectively.

Commitment fees ranging from 0.175% to 0.30% are charged quarterly in arrears on the aggregate unutilized portion of the Credit Agreement based upon the ratio of debt to total capitalization. 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 were 0.175% during 2014 and ranged from 0.175% to 0.2% during 2013. Letter of credit fees were 1.0% during 2014 and ranged from 1.0% to 1.125% during 2013. 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 restricted payments, including dividends and/or share repurchases, to (i) $40.0 million during the same fiscal quarter or (ii) $200.0 million in the aggregate after November 7, 2014. We did not declare or pay a dividend on our common stock in 2014 or 2013, and we have no plans to declare or pay a dividend in 2015. During the fourth quarter of 2014 we repurchased $5.5 million of our common stock, which represents the full amount repurchased under the program in 2014.

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.
