How much inventory do you really think we're talking about? The lousy 400 stores had moderate inventory levels to start with and the valuation of the affected games you're talking about had to be costed at the current average buy back cost. If you mess it and don't disclose up front, you run into accounting irregularities. The real issue here is believing that GME would have been dumb enough to miss such an obvious oversight. Give the CEO and COO a little credit for they have been in the business a number of years.....these guys aren't fools.
The company is sitting on a big chunk of cash that was generated through the IPO. Any write-off can be justified easily enough, if it's the right thing to do and well explained to the analysts. As an investor, I'm interested the sales growth and will base the multiple, on what I believe to be the future stream of earnings. A one time write-down....unless it was some incredible number. Frankly, I think it is immaterial in the overall scheme of things because of the explosive growth GME we'll see from them.
