Debt Disclosure [Abstract]
Debt	Debt Credit Facility We have a $100.0 million revolving credit facility with certain financial institutions, including up to $20.0 million in letters of credit and up to $10.0 million in swingline loans, which matures in August 2018 (the “Credit Facility”). Subject to the terms of our Credit Facility, we have the ability to increase the commitments to $150.0 million. At December 31, 2017 and 2016, we had no outstanding indebtedness under the Credit Facility. In addition, we had $2.8 million and $3.7 million in letters of credit outstanding as of December 31, 2017 and 2016, respectively. Our borrowing capacity is equal to 2.5x our Adjusted EBITDA less letters of credit outstanding under the Credit Facility. Our borrowing capacity under the Credit Facility could be reduced or eliminated depending on our future Adjusted EBITDA. Borrowings under the Credit Facility bear interest, at our option, at either a base rate or an adjusted Eurodollar rate. Base rate loans under the Credit Facility bear interest at a rate equal to the higher of (i) the prime rate as published in the Wall Street Journal, (ii) the Federal Funds Effective Rate plus 0.50% or (iii) the adjusted Eurodollar rate plus 1.00%, plus an applicable margin ranging from 0.50% to 1.50%, subject to adjustment based on the leverage ratio. Interest is in each case payable quarterly for base-rate loans. Eurodollar loans under the Credit Facility bear interest at an adjusted Eurodollar rate equal to the Eurodollar rate for such interest period multiplied by the statutory reserves, plus an applicable margin ranging from 1.50% to 2.50%. Interest is payable at the end of applicable interest periods for Eurodollar loans, except that if the interest period for a Eurodollar loan is longer than three months, interest is paid at the end of each three-month period. The unused portion of the Credit Facility is subject to a commitment fee ranging from 0.250% to 0.375% based on certain leverage ratios. The Credit Facility contains various covenants that, among other things, limit our ability to grant certain liens, make certain loans and investments, enter into mergers or acquisitions, enter into hedging transactions, change our lines of business, prepay certain indebtedness, enter into certain affiliate transactions, incur additional indebtedness or engage in certain asset dispositions. The Credit Facility also contains financial covenants, which, among other things, require us, on a consolidated basis, to maintain: (i) a ratio of total consolidated funded debt to adjusted EBITDA (as defined in our credit agreement) of not more than 2.5 to 1.0; and (ii) a ratio of EBITDA to interest expense of not less than 3.0 to 1.0. In addition, the Credit Facility contains customary events of default, including, among others, the failure to make required payments, the failure to comply with certain covenants or other agreements, breach of the representations and covenants contained in the agreements, default of certain other indebtedness, certain events of bankruptcy or insolvency and the occurrence of a change in control. On April 28, 2017, the Company obtained a limited waiver under its Revolving Credit Agreement, dated August 14, 2013, by and among FICV (as borrower), Amegy Bank National Association (as administrative agent), Capital One, National Association (as syndication agent) and the other lenders party thereto (the "Credit Agreement"), of its leverage ratio and interest coverage ratio for the fiscal quarters ending March 31, 2017 and June 30, 2017 (the “Waiver”) in order to not be in default for the first quarter of 2017.
