[1] Trading assets are primarily pledged against liabilities associated with repurchase agreements.

[2] As discussed in Note 21, "New Accounting Pronouncements," beginning January 1, 2020, an allowance for credit losses is recognized for debt securities while, prior to January 1, 2020, debt securities were assessed for other-than-temporary impairment. At December 31, 2019, we did not consider any of our debt securities to be other-than-temporarily impaired.

[3] See Note 4, "Securities," for additional information regarding the allowance for credit losses associated with our security portfolios.

[4] Primarily includes accrued interest receivables and customer acceptances.
