During the six months ended June 30, 2013, depreciation rates being used to compute the provision for depreciation of revenue earning equipment were adjusted on certain vehicles in our car rental operations to reflect changes in the estimated residual values to be realized when revenue earning equipment is sold. These depreciation rate changes resulted in net decreases of $14.8 million and $15.5 million in depreciation expense for the three-month and six-month periods ended June 30, 2013, respectively. Prospective changes include the impact of car sales channel diversification and acceleration of our retail sales expansion.
