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 the Credit Facility, we have the ability to increase the commitments to $150.0 million. At June 30, 2018 and December 31, 2017, we had $2.3 million and $2.8 million, respectively, in letters of credit outstanding and no outstanding borrowings under the Credit Facility. Our borrowing capacity is equal to 2.5 x our trailing 12-month Adjusted EBITDA less letters of credit outstanding under the Credit Facility. 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 a 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. As of June 30, 2018, we were in compliance with the covenants included in the Credit Agreement. 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. We are currently negotiating a new credit facility which we expect to be in place on or around the expiration of the existing Credit Facility in August 2018. Citibank Credit Facility In 2016, we entered into a three-year credit facility with Citibank N.A., UAE Branch in the amount of $6.0 million for the issuance of standby letters of credit and guarantees. The credit facility also allows for open ended guarantees. Outstanding amounts under the credit facility bear interest of 1.25% per annum for amounts outstanding up to one year. Amounts outstanding more than one year bear interest at 1.5% per annum. As of June 30, 2018 and December 31, 2017, we had $4.9 million and $2.6 million, respectively, in letters of credit outstanding. Insurance Notes Payable In 2017, we entered into three notes to finance our annual insurance premiums totaling $5.1 million. The notes bear interest at an annual rate of 2.9% with a final maturity date in October 2018. At June 30, 2018 and December 31, 2017, the total outstanding balance was $1.8 million and $4.7 million, respectively.
