On April 4, 2017, the Company entered into a Second Amended and Restated Credit Agreement (the “Credit Agreement”) with MUFG Union Bank, N.A., as administrative agent (“Agent”). The Credit Agreement amends and restates the Company’s existing Amended and Restated Credit Agreement, and increased the Company's borrowing capacity under the revolving credit facility to $400.0 million, with a $15.0 million letter of credit sub-facility. The Credit Agreement contains an increase option permitting the Company, subject to certain conditions and requirements, to arrange with existing lenders and/or new lenders to provide up to an aggregate of $100.0 million in additional commitments. Loan proceeds may be used for general corporate purposes, including acquisitions permitted under the Credit Agreement. The Company may prepay loans under the Credit Agreement in whole or in part at any time without premium or penalty. The fees incurred in connection with this Credit Agreement are classified as a direct deduction from long-term debt in the condensed consolidated balance sheets.

The loans bear interest, at the Company’s option, at either (i) a London Interbank Offered Rate (LIBOR) determined in accordance with the Credit Agreement, plus a margin ranging from 1.25% to 2.25%, or (ii) a base rate determined in accordance with the Credit Agreement, plus a margin ranging from 0.25% to 1.25%, in either case with such margin determined based on the Company’s consolidated leverage ratio for the preceding four fiscal quarter period. Interest is due and payable in arrears quarterly for base rate loans and at the end of an interest period for LIBOR rate loans. Principal, together with all accrued and unpaid interest, is due and payable on April 4, 2022. The Company elected option (i) and, as of September 30, 2018, the interest rate applicable to the revolving credit facility was 3.63%.

The Company’s obligations under the Credit Agreement are secured by substantially all of the Company’s assets. All of the Company’s existing and future material subsidiaries are required to guarantee its obligations under the Credit Agreement. The guarantees by future material subsidiaries are and will be secured by substantially all of the assets of such subsidiaries.

The Credit Agreement contains financial and non-financial covenants including debt ratio and interest coverage ratio requirements. The Company is currently in compliance with all the covenants under the credit facility.

On April 5, 2018, the Company's Board of Directors concluded the previously issued financial statements for (i) the quarterly periods ended September 30, June 30 and March 31, 2017, (ii) the annual period ended December 31, 2016 and (iii) the quarterly periods ended September 30 and June 30, 2016 (collectively, the “Non-Reliance Periods”) should be restated and should no longer be relied upon. On March 22, 2018 the Company entered a “First Reporting Extension” Agreement and on June 25, 2018 entered a “Second Reporting Extension” Agreement. These agreements are amendments to the Credit Agreement dated April 4, 2017 and provide credit accommodations to the Company in the form of modification of the reporting and Compliance Certificates. In 2018, the Company paid the Agent $0.8 million to extend the delivery date of the delinquent financial statements to March 16, 2019 pursuant to the Reporting Extension Agreement. In March 2019, the Company entered into a Third Reporting Extension Agreement and paid the Agent $0.1 million to extend the delivery date of any remaining delinquent financial statements to May 10, 2019.

As of September 30, 2018, the Company had $247.0 million outstanding under the revolving credit facility and $150.2 million unused revolving credit facility still available to borrow under the Credit Agreement.

The credit facility contains customary events of default including, among others, payment defaults, covenant defaults, inaccuracy of representations and warranties, cross-defaults to other material indebtedness, judgment defaults, a change of control default and bankruptcy, and insolvency defaults. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default under the loan agreement at a per annum rate of interest equal to 2.00% above the applicable interest rate. Upon an event of default, the lenders may terminate the commitments, declare the outstanding obligations payable by the Company to be immediately due and payable, and exercise other rights and remedies provided for under the credit facility.
