Anyone can help me with the exercise number 8?

Under IFRS firms can capitalize development outlays, whereas under US GAAP such outlays must be expensed as incurred. In its 2008 IFRS-based financial statements, Philips Electronics recognized a development asset of E357 million (E518 million in 2007). The company's development expenditures amounted to E233, E259, E295, E233, and E154 million in 2004, 2005, 2006, 2007, and 2008, respectively. In these years, total R&D expenditures were E1,615, E1,602, E1,659, E1,629, and E1,622 million, respectively. Philips' statutory tax rate is 25.5 percent. a Estimate the average expected life of Philips' investments in development at the end of 2008. b Using the estimate derived under a, what adjustments should an analyst make to the 2008 beginning balance sheet and 2008 income statement to immediately expense all development outlays and derecognize the development asset? c What adjustments should be made to the 2008 beginning balance sheet and 2008 income statement to recognize an asset for both research and development investments? Assume that the average expected life of Philips' investments in research at the end of 2007 and 2008 is equal to that of Philips' development investments at the end of 2008.
