Net Interest Income

Table 3: Summarized Average Balances and Net Interest Income (a)

(a)Interest income calculated as taxable-equivalent interest income. To provide more meaningful comparisons of interest income and yields for all interest-earning assets, as well as net interest margins, we use interest income on a taxable-equivalent basis in calculating average yields and net interest margins by increasing the interest income earned on tax-exempt assets to make it fully equivalent to interest income earned on taxable investments. This adjustment is not permitted under GAAP on the Consolidated Income Statement. For more information, see Table 35 Reconciliation of Taxable-Equivalent Net Interest Income (non-GAAP).

(b)Interest income from Interest-earning deposits with banks primarily includes interest earned on our balances held with the FRB and is reported as Other interest income on our Consolidated Income Statement.

Changes in net interest income and net interest margin result from the interaction of the volume and composition of interest-earning assets and related yields, interest-bearing liabilities and related rates paid and noninterest-bearing sources of funding. See Table 34 Average Consolidated Balance Sheet and Net Interest Analysis for additional information.
