Debt Disclosure [Abstract] |
Debt | Debt We have a loan agreement with a group of banks that was amended in January 2015 to fund our Aviation Acquisition, provide working capital for our continuing operations, and retire our existing debt. The loan agreement, which expires in January 2020, is comprised of a term loan facility and a revolving loan facility. The revolving loan facility provides for revolving loans and letters of credit. Financing costs associated with the inception of the amended loan agreement of approximately $2.7 million were capitalized and are being amortized over the five-year life of the loan. Our required term loan payments after December 31, 2016 are approximately $21.6 million in 2017, $28.1 million in 2018, $30.0 million in 2019, and $36.2 million in 2020. The amount of our term loan borrowings outstanding as of December 31, 2016 was $115.9 million. The maximum amount of credit available to us under the loan agreement for revolving loans and letters of credit as of December 31, 2016 was $150 million. We may borrow and repay the revolving loan borrowings as our cash flows require or permit. We pay an unused commitment fee and fees on letters of credit that are issued. We had approximately $100.4 million in revolving loan amounts outstanding and no letters of credit outstanding as of December 31, 2016. We had approximately $101 million in revolving loan amounts outstanding and no of letters of credit outstanding as of December 31, 2015. Under the loan agreement we may elect to increase the maximum availability of the term loan facility, the revolving loan facility, or a combination of both facilities up to an aggregate additional amount of $75 million. Total bank loan borrowed funds outstanding including term loan borrowings and revolving loan borrowings were approximately $216.3 million and $234.7 million as of December 31, 2016 and 2015, respectively. These amounts exclude unamortized deferred financing costs of approximately $1.7 million and $2.2 million as of December 31, 2016 and 2015, respectively. The fair value of outstanding debt under our bank loan facilities as of December 31, 2016 approximates its carrying value using Level 2 inputs based on market data on companies with a corporate rating similar to ours that have recently priced credit facilities. We pay interest on the term loan borrowings and revolving loan borrowings at LIBOR plus a base margin or at a base rate (typically the prime rate) plus a base margin. As of December 31, 2016, the LIBOR base margin was 2.25% and the base rate base margin was 1.00%. The base margins increase or decrease in increments as our Total Funded Debt/EBITDA Ratio increases or decreases. The loan agreement requires us to have interest rate hedges on a portion of the outstanding term loan for the first three years of the agreement. We executed interest rate hedges in February 2015 that complied with these terms. The amount of swapped debt outstanding as of December 31, 2016 was $100 million. After taking into account the impact of hedging instruments, as of December 31, 2016, interest rates on portions of our outstanding debt ranged from 2.96% to 4.75%, and the effective interest rate on our aggregate outstanding debt was 3.27%. Interest expense incurred on bank loan borrowings and interest rate hedges was approximately $7.8 million and $7.3 million during the years ended December 31, 2016 and 2015, respectively. The loan agreement contains collateral requirements to secure our loan agreement obligations, restrictive covenants, a limit on annual dividends, and other affirmative and negative covenants, conditions and limitations. Restrictive covenants include a maximum Total Funded Debt/EBITDA Ratio, which decreases over time, and a minimum Fixed Charge Coverage Ratio. We were in compliance with the financial covenants and other terms and conditions as of December 31, 2016.
