Revolving Credit Facility [Abstract]
Revolving Credit Facility	11. Revolving Credit Facility Our Second Restated Credit Agreement with The Frost National Bank (“Frost”) dated June 30, 2015, reinstated the credit facility with Frost which expired by its terms on April 30, 2015. The Second Restated Credit Agreement also amended certain provisions of the credit facility and restated the agreement with Frost in its entirety. The Second Restated Credit Agreement provides a $15.0 million revolving credit facility, with a $5.0 million letter of credit sub-facility. The outstanding balance of the revolving credit facility bears interest at a rate equal to the prime rate or LIBOR plus 2.5%, at our election. We pay an annual fee of 0.25% of the average daily unused balance of the credit facility and letter of credit fees at the rate of 1.00% per annum. The revolving credit facility contains covenants that, among other things, require us to maintain certain financial and operating ratios and restrict certain distributions, transactions and organizational changes. As of June 30, 2016 we were in compliance with all of our covenants and had no outstanding borrowings under this revolving credit facility. On December 17, 2015, we entered into a First Amendment to Second Restated Credit Agreement (the “First Amendment”) and a Revolving Facility B Agreement (the “Facility B Agreement”) with Frost. The First Amendment amended the existing Second Restated Credit Agreement with Frost to incorporate the additional credit facility reflected by the Facility B Agreement. The Facility B Agreement provided a new $30.0 million revolving credit facility (“Facility B”), in addition to the existing $15.0 million revolving credit facility with Frost. We may use Facility B loan proceeds solely for the purpose of making capital contributions to AHIC and HIC. We may borrow, repay and reborrow under the Facility B until December 17, 2017, at which time all amounts outstanding under the Facility B are converted to a term loan. In connection with Facility B, we paid Frost a one-time commitment fee of $75,000 and will pay Frost an additional quarterly fee through December 17, 2017 of 0.25% per annum of the average daily unused balance of Facility B. Facility B bears interest at a rate equal to the prime rate or LIBOR plus 3.00%, at our election. Until December 17, 2017, interest only on amounts from time to time outstanding under Facility B are payable quarterly. Any amounts outstanding on Facility B as of December 17, 2017 are converted to a term loan payable in quarterly installments over five years based on a seven year amortization of principal plus accrued interest. All remaining principal and accrued interest become due and payable on December 17, 2022. The obligations under Facility B are secured by the same collateral as the existing credit facility, being a security interest in the capital stock of AHIC and HIC. Facility B is subject to the same covenants as the existing credit facility. As of June 30, 2016, we had $30.0 million outstanding under Facility B.
