For banks located in U.S.-affiliated areas, market value level from quarterly Reports of Condition for U.S.-chartered depository institutions (forms FFIEC 031 and FFIEC 041).

For branches of U.S. banks located in U.S.-affiliated areas, quarterly level for significant branches (those with total assets of at least $2 billion or total gross commitments to purchase foreign currencies and U.S. dollar exchange of at least $5 billion) and year-end level for other branches (those with total assets in excess of $250 million) from the Foreign Branch Report of Condition (form FFIEC 030), Securities and obligations of U.S. government and states and political subdivisions in the U.S. (FORB6597). Capital gains are computed using the change in the Merrill Lynch AAA Treasury par weighted price index. Transactions are calculated as the change in market value level less capital gains less any other volume changes. Data for the most recent ten years show no significant seasonality.
