Note 2. Long-term Debt
Long-term debt consisted of the following:
We had two outstanding unsecured senior note agreements with an aggregate amount outstanding of $120.0 million at December 31, 2015. At December 31, 2014, we had three outstanding unsecured senior note agreements with an aggregate amount outstanding of $155.7 million. These notes include scheduled principal payments with maturities that range from 2016 to 2021, of which $25.0 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 4.68% and 4.87% at December 31, 2015 and 2014, respectively.
On December 15, 2015, we entered into an amended and restated credit agreement with Wells Fargo Bank, National Association ("Wells Fargo") serving as administrative agent for the lenders (the "2015 Credit Agreement"). The 2015 Credit Agreement provides for a five-year, $250.0 million senior unsecured revolving line of credit. We may also request an increase in the line of credit commitments up to an aggregate of $350.0 million, which may include Term Loan Commitments, in minimum increments of $25.0 million. Of the $250.0 million line of credit commitments, up to $100.0 million may be used for letters of credit and $30.0 million may be used for borrowings under the Wells Fargo Sweep Plus Loan Program (the "Sweep Program"). We utilize the Sweep Program to manage our daily cash needs, as it automatically initiates borrowings to cover overnight cash requirements primarily for working capital needs.
At our option, borrowings under the 2015 Credit Agreement bear interest at either: (i) LIBOR plus an applicable margin (based on our ratio of debt-to-total capitalization) that ranges from 1.0% to 1.50%; or (ii) a Base Rate plus an applicable margin (based on our ratio of debt-to-total capitalization) that ranges from 0.0% to 0.5%. Loans under the Sweep Program bear interest at the LIBOR plus applicable margin rate. Letter of credit fees equal to the applicable margin for LIBOR and Base Rate loans are charged quarterly in arrears on the daily average aggregate stated amount of all letters of credit outstanding during the quarter. Commitment fees ranging from 0.125% to 0.2% (based upon the ratio of debt-to-total capitalization) are charged quarterly in arrears on the aggregate unutilized portion of the 2015 Credit Agreement. Wells Fargo, as administrative agent, also receives an annual fee for providing administrative services.
For the periods covered under the 2015 Credit Agreement, the applicable margin and letter of credit fees were 1.0% and commitment fees were 0.125%.
The 2015 Credit Agreement superseded and replaced our previous five-year, $200.0 million senior unsecured revolving credit facility dated August 10, 2011, as amended on November 7, 2014 (the "2011 Credit Agreement"). For periods in 2015 and 2014 under the 2011 Credit Agreement, the applicable margin and letter of credit fees were 1.0%, and commitment fees were 0.175%.
There were $67.7 million and $63.2 million of outstanding letters of credit at December 31, 2015 and 2014, respectively.
The 2015 Credit Agreement includes a provision limiting our ability to make restricted payments, including dividends and payments for share repurchases, unless, among other conditions, no defaults or events of default under the 2015 Credit Agreement are ongoing (or would be caused by such restricted payment). We did not declare or pay a cash dividend on our common stock in 2015 or 2014, and we have no plans to declare or pay a cash dividend in 2016. Our share repurchases are described above in “Stock Repurchase Program.”
Our two outstanding senior note agreements and 2015 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 material domestic subsidiaries of the Company would be required to guarantee payment of all of our obligations under these agreements. We were in compliance with all covenants in our outstanding debt instruments for the period ended December 31, 2015.
As of December 31, 2015, aggregate maturities of long-term debt are as follows:
