Revolving Credit Facility [Abstract]
Revolving Credit Facility	11. Revolving Credit Facility Our Second Restated Credit Agreement with Frost 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 (“Facility A’), with a $5.0 million letter of credit sub-facility. The outstanding balance of the Facility A 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 Facility A and letter of credit fees at the rate of 1.00% per annum. As of September 30, 2016, we had no outstanding borrowings under Facility A. On December 17, 2015, we entered into a First Amendment to Second Restated Credit Agreement and a Revolving Facility B Agreement (the “Facility B Agreement”) with Frost to provide a new $30.0 million revolving credit facility (“Facility B”), in addition to Facility A. On November 1, 2016, we amended the Facility B Agreement with Frost to extend by one year the termination date for draws under Facility B and the maturity date for amounts outstanding thereunder. We paid Frost a commitment fee of $75,000 when Facility B was established and an additional $30,000 fee when Facility B was extended. We may use Facility B loan proceeds solely for the purpose of making capital contributions to AHIC and HIC. As amended, we may borrow, repay and reborrow under Facility B until December 17, 2018, at which time all amounts outstanding under Facility B are converted to a term loan. Through December 17, 2018, we pay Frost a quarterly fee 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, 2018, 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, 2018 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 on Facility B become due and payable on December 17, 2023. As of September 30, 2016, we had $30.0 million outstanding under Facility B. The obligations under both Facility A and Facility B are secured by a security interest in the capital stock of AHIC and HIC. Both Facility A and Facility B contain covenants that, among other things, require us to maintain certain financial and operating ratios and restrict certain distributions, transactions and organizational changes. As of September 30, 2016, we were in compliance with all of these covenants.
