The fixed charge coverage ratio compares (a) EBITDA (as adjusted and defined in the Credit Agreement) less (1) cash income tax expense, (2) non-financed capital expenditures, and (3) cash dividends and distributions to (b) interest expense plus (1) scheduled principal payments and (2) stock purchases. The Fourth Amendment provides that the fixed charge coverage ratio may not be less than 1.25 to 1 as of the end of any fiscal quarter. The consolidated leverage ratio covenant was amended and may not exceed (a) 4.00 to 1 at the end of the fiscal quarters ending during the period from and including June 30, 2016 through and including March 31, 2018, (b) 3.75 to 1 at the end of the fiscal quarters ending during the period from and including June 30, 2018 through and including December 31, 2018, and (c) 3.5 to 1 at the end of each of the fiscal quarters thereafter.

In addition, subsequent to the Fourth Amendment, borrowings will bear interest at the British Bankers Association LIBOR rate plus 2.25% to 4.00%, or an alternate base rate plus 0.00% to 1.00%, in each case depending on one of our financial ratios, and the commitment fee on unused portions of the facility will range from 0.35% to 0.75%.
          
Debt instrument, collateral description          
The Fourth Amendment also resulted in additional modifications, including a requirement that all obligations under the Credit Agreement and the guarantees of such obligations be secured by first-lien security interests in substantially all of our assets and the assets of our subsidiaries (limited, in the case of foreign subsidiaries, to 66% of the voting stock or equity interests of first-tier foreign subsidiaries).
