The franchise agreements generally limit the location of the dealership and provide the auto manufacturer approval rights over changes in dealership management and ownership. The auto manufacturers are also entitled to terminate the franchise agreement if the dealership is in material breach of the terms. Our ability to expand operations depends, in part, on obtaining consents of the manufacturers for the acquisition of additional dealerships.

Because net loss performance can vary substantially over time, estimating net losses requires assumptions about matters that are uncertain. The allowance for loan and lease losses is determined using a net loss timing curve, primarily based on the composition of the portfolio of managed receivables and historical gross loss and recovery trends. Determining the appropriateness of the allowance for loan and lease losses requires management to exercise judgement about matters that are inherently uncertain, including the timing and distribution of net losses that could materially affect the allowance or loan and lease losses and, therefore, net earnings.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We also use estimates in the calculation of various expenses, accruals and reserves, including anticipated losses related to workers’ compensation insurance; anticipated losses related to self-insurance components of our property and casualty and medical insurance; self-insured lifetime lube, oil and filter service contracts; discretionary employee bonuses, the Transition Agreement with Sidney B.

This warranty is based on mileage and time. We also offer a mileage and time based warranty on parts used in our service repair work and on tire purchases. The cost that may be incurred for these warranties is estimated at the time the related revenue is recorded. A reserve for these warranty liabilities is estimated based on current sales levels, warranty experience rates and estimated costs per claim. The annual activity for reserve increases and claims is immaterial.
