a. Describe the impact that implementing FAS 157 had on EMC's financial statements, based on the footnote information provided. Can you tell if the current economic conditions influenced the valuation of their financial assets and liabilities from this disclosure? If yes, what information told you this, if not, what information do you feel is missing? As an investor, would this disclosure give you enough information to be satisfied that this is a truly fair valuation? Why or why not? b. From the disclosures and computations for the pension plans that EMC has responsibility for (primarily from the previous acquisition of Data General-current EMC employees are covered by a 401k plan), what impacts did the economic situation have in the plan from 2007 to 2008? Be specific. Do you think they should convert to a Cash Balance Plan? Why do you think they have not done this, when many other major companies have? (you can do other research for this outside the footnote if it helps) c. If these 2 sections were tagged with XBRL, and you had access to software that could use XBRL data, would you be able to answer questions A and B faster and more thoroughly? Or is good old- fashioned reading and analysis just as effective in this case?
