CREDIT FACILITIES

As of December 31, 2015, we had unsecured committed credit facilities with three banks as well as a term commitment with one of these banks. We had with Wells Fargo Bank, N.A., a $100.0 million credit facility which will expire on July 12, 2020, and a $75.0 million term commitment with principal due and payable on September 15, 2019. On July 13, 2015, we amended our existing credit agreement, dated June 1, 2012, as previously amended, with Wells Fargo Bank, N.A. This amendment lowered the maximum principal amount of the unsecured line of credit to $100.0 million from $175.0 million and extended the term of the credit agreement to July 12, 2020 from May 31, 2016. Also on July 13, 2015, we entered into a new credit agreement with U.S. Bank, N.A. The new credit agreement is an unsecured line of credit of $75.0 million and expires on July 13, 2020. We also had a $75.0 million credit facility with BMO Harris Bank, N.A., which will expire on March 5, 2020. On March 5, 2015, we replaced our existing $75.0 million credit agreement with BMO Harris Bank, N.A., with a new credit agreement. The new BMO Harris Bank, N.A., agreement includes a $75.0 million credit facility which will expire on March 5, 2020. Borrowings under these credit facilities and term note bear variable interest (0.9305% at December 31, 2015) based on the London Interbank Offered Rate (“LIBOR”), with interest on the term note effectively fixed at 2.5% with an interest rate swap agreement.

As of December 31, 2015 and 2014, our outstanding debt totaled $75.0 million. The $325.0 million of credit available under these facilities is further reduced by $31.0 million in stand-by letters of credit under which we are obligated. Each of the debt agreements includes, among other things, financial covenants requiring us (i) not to exceed a maximum ratio of total debt to total capitalization and/or (ii) not to exceed a maximum ratio of total funded debt to earnings before interest, income taxes, depreciation and amortization (as such terms are defined in each credit facility). At December 31, 2015, we were in compliance with these covenants.

At December 31, 2015, the aggregate future maturities of long-term debt by year are as follows (in thousands):



2016	$	—
2017	—
2018	—
2019	75,000
2020	—
Total	$	75,000

The carrying amounts of our long-term debt approximate fair value due to the duration of the notes and the variable interest rates.
