On December 1, 2016, the Company acquired all of the outstanding capital stock of Donna Karan International (“DKI”) from LVMH Moet Hennessy Louis Vuitton Inc. (“LVMH”) for a total purchase price of approximately $650 million, subject to certain adjustments. The stock purchase agreement provided for the purchase price to be paid by the Company with a combination of (i) cash, (ii) $75 million of newly issued shares of G-III common stock, par value $0.01 per share, equivalent to approximately 2.6 million shares, to the seller and (iii) a junior lien secured promissory note in favor of LVMH in the principal amount of $125 million. The Company plans to pay the cash portion of the purchase price from the proceeds of $350.0 million of borrowings under a senior secured term loan facility (“The Term Loan”) and the balance from borrowings under a $650.0 million senior secured asset-based revolving credit facility (the “New ABL Facility”).

The Term Loan will mature in December 2022. The Term Loan is subject to amortization payments of 0.625% of the original aggregate principal amount of the Term Loan per quarter, with the balance due at maturity. Interest on the outstanding principal amount of the Term Loan accrues at a rate equal to LIBOR plus an applicable margin of 5.25% or an alternate base rate (defined as the greatest of (i) the “prime rate” as published by the Wall Street Journal from time to time, (ii) the federal funds rate plus 0.5% and (iii) the LIBOR rate for a borrowing with an interest period of one month) plus 4.25%, per annum, payable in cash. The Term Loan may be prepaid, at the option of the Company, in whole or in part, at any time at par plus accrued interest, and, in the case of prepayments from the proceeds of certain refinancings prior to December 1, 2017, subject to a 1% prepayment fee applicable. The Term Loan is required to be prepaid with the proceeds of certain asset sales if such proceeds are not applied as required by the Term Loan Credit Agreement within certain specified deadlines. The Term Loan is also required to be prepaid in an amount equal to 75% of the Excess Cash Flow (as defined in the Term Loan Credit Agreement) of the Company with respect to each fiscal year ending on or after January 31, 2018. The percentage of Excess Cash Flow that must be so applied is reduced to 50% if the Company’s senior secured leverage ratio is less than 3.00 to 1.00, to 25% if the Company’s senior secured leverage ratio is less than 2.75 to 1.00 and to 0% if the Company’s senior secured leverage ratio is less than 2.25 to 1.00.

Amounts available under the ABL Facilities are subject to borrowing base formulas and over advances as specified in the ABL Credit Agreement. Borrowings bear interest, at the Company’s option, at LIBOR plus a margin of 1.25% to 1.75% or an alternate base rate (defined as the greatest of (i) the “prime rate” of JPMorgan Chase Bank, N.A. from time to time, (ii) the federal funds rate plus 0.5% and (iii) the LIBOR rate for a borrowing with an interest period of one month) plus a margin of 0.25% to 0.75%, with the applicable margin determined based on the Company’s availability under the ABL Credit Agreement.

Upon closing of the acquisition of Donna Karan, the Company’s previous credit agreement (see note 5) was refinanced and replaced by the New ABL Facility.
