Note 2. Long-term Debt
Long-term debt consisted of the following:
We had one unsecured senior note agreement with an amount outstanding of $45.0 million and $95.0 million at December 31, 2018 and 2017, respectively. Our unsecured senior note agreement called for a scheduled principal payment of $50.0 million, which was paid on January 3, 2018. A second scheduled principal payment of $45.0 million is due on January 3, 2021. Interest rates on the January 3, 2018 and January 3, 2021 scheduled principal payments were 4.00% and 4.79%, respectively. The effective average interest rate on our outstanding senior note agreement was 4.79% and 4.37% at December 31, 2018 and 2017, 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 fully 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.
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%. 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.
For each of the years ended December 31, 2018 and 2017, the applicable margin on LIBOR loans and letter of credit fees was 1.0% and commitment fees were 0.125%. There were $61.5 million and $71.4 million of outstanding letters of credit at December 31, 2018 and 2017, respectively.
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, 2018, our only long-term debt was $45 million, which will mature in 2021.
