1. Read Note 2 from the 2009 Apples 10-K/A (see below), for each balance sheet item adjusted, explain why the adjustment was necessary. Hint: Other current assets and other assets include the pro rata cost of products (such as the iPhone) that were sold but for which revenue was deferred. Accrued expenses and other non-current liabilities include current and non-current portion of warranty accruals, respectively.
2. What was the cash flow effect of the new revenue recognition principle?

The following table present the effects of the retrospective adoption of the new accounting principles to the Company's previously reported financial statements as of September 26, 2009:
