We have one unsecured senior note agreement with an amount outstanding of $95.0 million at December 31, 2016. At December 31, 2015, we had two unsecured senior note agreements with an aggregate amount outstanding of $120.0 million. The remaining unsecured senior note agreement calls for two scheduled principal payments of $50.0 million and $45.0 million on January 3, 2018 and January 3, 2021, respectively. Interest rates on the January 3, 2018 and January 3, 2021 scheduled principal payments are 4.00% and 4.79%, respectively. The effective average interest rates on our outstanding senior note agreements were 4.37% and 4.68% at December 31, 2016 and 2015, 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 "Credit Agreement"). The Credit Agreement originally provided for a five-year, $250.0 million senior unsecured revolving line of credit and a $100.0 million accordion feature, which if exercised and approved, would expand the total borrowing capacity up to an aggregate of $350.0 million. On September 9, 2016, we exercised a portion of the accordion feature and entered into an amendment to the Credit Agreement to increase the aggregate commitments from existing lenders by $50.0 million to an aggregate of $300.0 million. Of the $300.0 million line of credit commitments under the Credit Agreement, as amended, 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. The Credit Agreement matures on December 15, 2020. At our option, borrowings under the Credit Agreement bear interest at either: (i) LIBOR plus an applicable margin (based on our ratio of net 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 net 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 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 net debt-to-total capitalization) are charged quarterly in arrears on the aggregate unutilized portion of the Credit Agreement. Wells Fargo, as administrative agent, also receives an annual fee for providing administrative services. For the year ended December 31, 2016, the applicable margin on LIBOR loans was 1.0% and commitment fees were 0.125%. For the year ended December 31, 2015, the applicable margin on LIBOR loans was 1.0% and commitment fees ranged from 0.125% to 0.175%. There were $74.6 million and $67.7 million of outstanding letters of credit at December 31, 2016 and 2015, respectively. Letter of credit fees remained at 1.0% during the years ended December 31, 2016 and 2015. The 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 Credit Agreement are ongoing (or would be caused by such restricted payment). Our senior note agreement and 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. As of December 31, 2016, aggregate maturities of long-term debt are as follows:
(In thousands) | Total
2017 | $ | — |
