In November 2018, the Company repaid the previously outstanding borrowings under its revolving credit facility. At December 28, 2018, the Company’s borrowing capacity under the revolving credit facility was $2.25 billion.

The credit agreement governing the Company’s revolving credit facility and term loans (as amended, the “Credit Agreement”) requires the Company to comply with certain financial covenants with respect to the revolving credit facility and Term Loan A-1, consisting of a Leverage Ratio and an Interest Coverage Ratio (each as defined below). These covenants are based upon a trailing twelve-month consolidated adjusted EBITDA as defined in the Credit Agreement (“Adjusted EBITDA”). Adjusted EBITDA is defined as net income (loss) plus interest expense, income tax expense (benefit) and depreciation and amortization as well as other contractual adjustments as provided for in the Credit Agreement.

Pursuant to the Credit Agreement, the Company is required to maintain a maximum ratio of total funded debt to trailing twelve-month Adjusted EBITDA (“Leverage Ratio”) at the end of each quarter of 4.25 to 1.00 through the quarter ending October 4, 2019, 4.00 to 1.00 through the quarter ending October 2, 2020, and 3.75 to 1.00 thereafter. In addition, the Company is required to maintain a minimum ratio of Adjusted EBITDA to interest expense (“Interest Coverage Ratio”), both calculated on a trailing twelve-month basis, at the end of each quarter of 3.50 to 1.00. As of December 28, 2018, the Company was in compliance with all financial covenants under the Credit Agreement.

The Credit Agreement also requires the Company and its subsidiaries to comply with customary covenants that include, among others, limitations on the incurrence of additional debt, liens on property, acquisitions and investments, loans and guarantees, mergers, consolidations, liquidations and dissolutions, asset sales, dividends and other payments in respect of the Company’s capital stock, prepayments of certain debt, transactions with affiliates and certain modifications of organizational documents and certain debt agreements. In addition, the indentures governing the Company’s 2026 Senior Unsecured Notes and the 2024 Convertible Notes contain restrictive covenants that limit the Company’s and its subsidiaries’ ability to, among other things, consolidate, merge or sell all or substantially all of their assets; create liens; and incur, assume or guarantee additional indebtedness.
