Beginning in 1996, level estimated by FOF Section as the sum of the market value of property-casualty insurance C-corporations and S-corporations. The market value of S-corporations is estimated by multiplying the net worth data of S-corporations in financial and nonfinancial industries (identified by 2-digit NAICS codes) from the IRS SOI Table S- Corporation Returns: Balance Sheet and Income Statement Items, by Major Industry, by the average ratio of market value to net worth from Standard and Poor's Compustat for public companies in the same industries. A ratio of how much property and casualty insurance companies make up each industry?s market value from Standard and Poor's Compustat, with property-casualty insurance companies being identified from SIC and NAICS codes, is used to split out the property-casualty insurance share of the calculated market level values from SOI for each industry. The market value of C-corporations is estimated by multiplying the revenue data of companies that appear on Forbes' annual list of America's Largest Private Companies by the ratio of total market value to total revenue of public companies from Standard and Poor's Compustat with similar industry, employment, and revenue profiles. The total market value of C-corporations is allocated to property and casualty insurance companies using the same splits available from the S-corporations calculations. The total market value of C-corporations and S-corporations is adjusted downward by 25 percent to reflect the lack of liquidity of closely held shares. Series has no transactions component.
