This appendix lists the companies that were part of our study. The first three subsections list the 1,000 largest sample for 1950, divided into three groups, the 200 largest, 201–500 largest, and 501–1,000 largest. Column 2 of these three subsections indicates each firm's status as of 1972, where SR ≡ survived, AQ ≡ acquired through merger, LQ ≡ liquidated, PI ≡ privately held (i.e., the firm survived, but because of private control of the firm not enough information was available to include it in the sample), ID ≡ insufficient data to include in sample, NI ≡ no information as to what happened to the firm. Column 3 reports the same information for firms that is available in the 1980 Moody's Industrial Manual. If the firm was in our sample of 600 companies used to obtain original profit estimates, its rank in 1950–52 is presented in column 4. Column 5 lists either the company's current name, if the company survived, or, in parentheses, the name of the firm that acquired it and the year of acquisition.

Subsection D lists the names and 1950–52 profit ranks of companies in the 1972 1,000 largest sample that were not in the 1950 1,000 largest included in the study. Subsection E lists firms and 1950–52 profit ranks that were included in our study and that were in neither the 1950 nor the 1972 1,000 largest groups.
