Credit Facility

We have a $1.85 billion revolving syndicated credit facility that matures in January 2021. This syndicated credit facility is comprised of 18 financial institutions, including eight manufacturer-affiliated finance companies. As of December 31, 2015, our credit facility provides for up to $1.45 billion in new vehicle inventory floor plan financing, up to $200 million in used vehicle inventory floor plan financing and a maximum of $200 million in revolving financing for general corporate purposes, including acquisitions and working capital. This credit facility may be expanded to $2.1 billion total availability, subject to lender approval.

We may request a reallocation of any unused portion of our credit facility provided that the used vehicle inventory floor plan commitment does not exceed $250 million, the revolving financing commitment does not exceed $300 million, and the sum of those commitments plus the new vehicle inventory floor plan financing commitment does not exceed the total aggregate financing commitment. All borrowings from, and repayments to, our lending group are presented in the Consolidated Statements of Cash Flows as financing activities.

The new vehicle floor plan commitment is collateralized by our new vehicle inventory. Our used vehicle inventory financing facility is collateralized by our used vehicle inventory that has been in stock for less than 180 days. Our revolving line of credit is secured by our outstanding receivables related to vehicle sales, unencumbered vehicle inventory, other eligible receivables, parts and accessories and equipment.

We have the ability to deposit up to $50 million in cash in Principal Reduction “PR” accounts associated with our new vehicle inventory floor plan commitment. The PR accounts are recognized as offsetting credits against outstanding amounts on our new vehicle floor plan commitment and would reduce interest expense associated with the outstanding principal balance. As of December 31, 2015, we did not have any amounts deposited in our PR accounts.

If the outstanding principal balance on our new vehicle inventory floor plan commitment, plus requests on any day, exceeds 95% of the loan commitment, a portion of the revolving line of credit must be reserved. The reserve amount is equal to the lesser of $15.0 million or the maximum revolving line of credit commitment less the outstanding balance on the line less outstanding letters of credit. The reserve amount will decrease the revolving line of credit availability and may be used to repay the new vehicle floor plan commitment balance.

The interest rate on the credit facility varies based on the type of debt, with the rate of one-month LIBOR plus 1.25% for new vehicle floor plan financing, one-month LIBOR plus 1.50% for used vehicle floor plan financing; and a variable interest rate on the revolving financing ranging from the one-month LIBOR plus 1.25% to 2.50%, depending on our leverage ratio. The annual interest rate associated with our new vehicle floor plan commitment, excluding the effects of our interest rate swaps, was 1.68% at December 31, 2015. The annual interest rate associated with our used vehicle inventory financing facility and our revolving line of credit was 1.93% and 2.18%, respectively, at December 31, 2015.

Under the terms of our credit facility we are subject to financial covenants and restrictive covenants that limit or restrict our incurring additional indebtedness, making investments, selling or acquiring assets and granting security interests in our assets. As of December 31, 2015, we were in compliance with all financial covenants. The table below details our financial covenants:
