This excerpt taken from the AN 10-K filed Feb 17, 2010.
We are subject to interest rate risk in connection with our floorplan payable, revolving credit facility, term loan facility, and floating rate senior unsecured notes that could have a material adverse effect on our profitability.
Most of our debt, including our floorplan payable, is subject to variable interest rates. Our variable interest rate debt will fluctuate with changing market conditions and, accordingly, our interest expense will increase if interest rates rise. In addition, our net inventory carrying cost (new vehicle floorplan interest expense net of floorplan assistance that we receive from automotive manufacturers) may increase due to changes in interest rates, inventory levels, and manufacturer assistance. We cannot assure you that a significant increase in interest rates would not have a material adverse effect on our business, financial condition, results of operations, or cash flows.
