|Debt Disclosure [Abstract]|
We have a loan agreement with a group of banks, which was amended in January 2015 primarily to fund our Aviation Acquisition and provide working capital for our continuing operations. 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.
Our required term loan payments after June 30, 2017 are approximately $11.2 million in 2017, $28.1 million in 2018, $30.0 million in 2019, and $36.3 million in 2020. The amount of term loan borrowings outstanding as of June 30, 2017 was approximately $105.6 million.
The maximum amount of credit available to us under the loan agreement for revolving loans and letters of credit as of June 30, 2017 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 $95.2 million in revolving loan amounts outstanding and no letters of credit outstanding as of June 30, 2017. We had approximately $100.4 million in revolving loan amounts outstanding and no letters of credit outstanding as of December 31, 2016.
Under the loan agreement we may elect to increase the maximum availability of the term loan facility, the revolving loan facility, or 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 $200.8 million and $216.3 million, as of June 30, 2017 and December 31, 2016, respectively. These amounts exclude unamortized deferred financing costs of approximately $1.4 million and $1.7 million as of June 30, 2017 and December 31, 2016, respectively, which are being amortized over a five-year period through July 2020. The fair value of outstanding debt as of June 30, 2017 under our bank loan facilities 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 June 30, 2017, 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 swap agreements in February 2015 that complied with the loan agreement. The notional amount of the interest rate swap agreements as of June 30, 2017 was $85 million.
After taking into account the impact of interest rate swap agreements, as of June 30, 2017, interest rates on portions of our outstanding debt ranged from 3.42% to 5.25%, and the effective interest rate on our aggregate outstanding debt was 3.60%.
Interest expense incurred on bank loan borrowings and interest rate hedges was approximately $1.9 million and $1.9 million for the quarters ended June 30, 2017 and 2016, respectively. Interest expense incurred on bank loan borrowings and interest rate hedges was approximately $3.8 million and $3.8 million for the six months ended June 30, 2017 and 2016, respectively.
The loan agreement contains collateral requirements to secure our borrowings and other 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 required ratios and other terms and conditions at June 30, 2017.
The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.
