Subsequent Events [Abstract]
Subsequent Event	Note 10— Subsequent Event On October 26, 2018, the Company and a syndicate of banks, led by Citibank, N.A., as agent, entered into the Second A&R Credit Agreement. The Second A&R Credit Agreement amends and restates the Company’s existing credit facility previously entered into on May 9, 2017, and consists of a $150.0 million revolving loan facility, with a $20.0 million sublimit for swingline borrowings and a $15.0 million sublimit for the issuance of letters of credit (the “Second A&R Credit Facility”). Under certain circumstances, the Company has the right to increase the Second A&R Credit Facility by an amount not to exceed $100.0 million. The Second A&R Credit Agreement is collateralized by substantially all of the Company’s assets, including a pledge of certain of its accounts receivable, deposit accounts, intellectual property, investment property, and equipment. Loans under the Second A&R Credit Facility bear interest through maturity at a variable rate based upon, at the Company’s option, an annual rate of either a Base Rate or a LIBOR rate, plus an applicable margin (“Base Rate Borrowings” and “LIBOR Rate Borrowings”). The Base Rate is defined as a fluctuating interest rate equal to the greatest of (1) the federal funds rate plus 0.50%, (2) Citibank, N.A.’s prime rate, and (3) one month LIBOR rate plus 2.00%. The applicable margin is between 0.25% to 1.25% for Base Rate Borrowings and between 1.25% and 2.25% for LIBOR Rate Borrowings based on the Company maintaining certain leverage ratios. The fee for undrawn amounts under the Second A&R Credit Facility ranges, based on the applicable leverage, from 0.225% to 0.400%. The Company will also be required to pay customary letter of credit fees, as necessary. The Second A&R Credit Facility matures and all outstanding amounts become due and payable on May 9, 2022. The Second A&R Credit Agreement contains customary conditions to borrowings, events of default and covenants, including covenants that restrict our ability to sell assets, make changes to the nature of our business, engage in mergers or acquisitions, incur, assume or permit to exist additional indebtedness and guarantees, create or permit to exist liens, pay dividends, issue equity instruments, make distributions or redeem or repurchase capital stock or make other investments, engage in transactions with affiliates and make payments in respect of subordinated debt. The Second A&R Credit Agreement also requires the Company to maintain compliance with (a) a maximum ratio of consolidated funded debt to consolidated EBITDA of 3.50 to 1.00 and (b) a minimum ratio of consolidated EBITDA to interest expense of at least 3.00 to 1.00. The Company entered into the Second A&R Credit Agreement primarily to lower its borrowing costs and to change from an asset-based structure to a cash-flow based structure.

Note 10— Subsequent Event

On October 26, 2018, the Company and a syndicate of banks, led by Citibank, N.A., as agent, entered into the Second A&R Credit Agreement. The Second A&R Credit Agreement amends and restates the Company’s existing credit facility previously entered into on May 9, 2017, and consists of a $150.0 million revolving loan facility, with a $20.0 million sublimit for swingline borrowings and a $15.0 million sublimit for the issuance of letters of credit (the “Second A&R Credit Facility”). Under certain circumstances, the Company has the right to increase the Second A&R Credit Facility by an amount not to exceed $100.0 million. The Second A&R Credit Agreement is collateralized by substantially all of the Company’s assets, including a pledge of certain of its accounts receivable, deposit accounts, intellectual property, investment property, and equipment.

Loans under the Second A&R Credit Facility bear interest through maturity at a variable rate based upon, at the Company’s option, an annual rate of either a Base Rate or a LIBOR rate, plus an applicable margin (“Base Rate Borrowings” and “LIBOR Rate Borrowings”). The Base Rate is defined as a fluctuating interest rate equal to the greatest of (1) the federal funds rate plus 0.50%, (2) Citibank, N.A.’s prime rate, and (3) one month LIBOR rate plus 2.00%. The applicable margin is between 0.25% to 1.25% for Base Rate Borrowings and between 1.25% and 2.25% for LIBOR Rate Borrowings based on the Company maintaining certain leverage ratios. The fee for undrawn amounts under the Second A&R Credit Facility ranges, based on the applicable leverage, from 0.225% to 0.400%. The Company will also be required to pay customary letter of credit fees, as necessary.

The Second A&R Credit Facility matures and all outstanding amounts become due and payable on May 9, 2022.

The Second A&R Credit Agreement contains customary conditions to borrowings, events of default and covenants, including covenants that restrict our ability to sell assets, make changes to the nature of our business, engage in mergers or acquisitions, incur, assume or permit to exist additional indebtedness and guarantees, create or permit to exist liens, pay dividends, issue equity instruments, make distributions or redeem or repurchase capital stock or make other investments, engage in transactions with affiliates and make payments in respect of subordinated debt.
