Hang on though, this part has nothing to do with repair costs. This just sounds like an accounting issue, right? If anything I would expect this to benefit Hertz since they could write off the higher loss in their taxes immediately, instead of waiting until future years to write the value off via depreciation.
On the other hand, I can see how this would make their numbers look worse at a glance since it shows up as though they lost money, but in fact no actual assets have been lost; they have the same car, it was repaired, and the repair was paid for by insurance, but now it looks like they took a loss because an arbitrary accounting rule forces them to adjust their balance sheet in a different way than they would otherwise.
Not sure if I'm understanding this right but it sure sounds like Hertz is flat-out admitting that they're making sub-optimal business decisions to make their numbers look better. Wouldn't that be a blatant violation of their fiduciary duties?
