Brave New Footnote: What SFAS No. 107 Disclosures Mean To Analysts: Historical cost accounting doesn't always present the most realistic balance sheets—especially where assets and liabilities are largely composed of "promises to pay" which have a market value that reflects current interest rates. SFAS No. 107 will provide disclosures in 1992 annual reports that show what these assets and liabilities are really worth right now, as opposed to what they were worth when first recorded. For value hunters, the disclosures may yield some pleasant surprises; and for those who are concerned with how a company allocates its capital, some new information for evaluating managements.
