Level at book value from quarterly Reports of Condition for U.S.-chartered commercial banks (forms FFIEC 031 and FFIEC 041). Series is calculated as the sum of: for FFIEC 031 reporters, schedule RC-H-Selected Balance Sheet Items for Domestic Offices, a fraction of Investments in mutual funds and other equity securities with readily determinable fair values (series RCONA511), where the fraction is calculated from RC-B-Securities, as the ratio of Amortized cost to Fair Value of Available-for-sale Investments in mutual funds and other equity securities with readily determinable fair values (RCFDA510 divided by RCFDA511); for FFIEC 041 reporters, schedule RC-B-Securities, Investments in mutual funds and other equity securities with readily determinable fair values, Available for sale, Amortized cost (series RCONA510). Level is converted to market value using percentage changes in the NYSE Composite Index of Common Stock Prices (FOF series FI073164003). Unadjusted flow is the change in the book-value level; data for the most recent ten years show no significant seasonality.
