This industry Subtopic supplements ASC 320-10 for depository and financial institutions (banks, thrifts, savings banks, credit unions, finance companies, insurance entities), addressing how they measure and disclose investments in debt and equity securities. Its core content is disclosure: securities must be broken out by prescribed major security types and by at least four maturity groupings, collateral pledged must be disclosed, and the accounting policy (including basis for classification) explained. It also confirms that amortization or accretion of debt securities generally runs from the purchase date to maturity, and that bank regulators' general divestiture authority does not by itself defeat held-to-maturity classification.
Key points (7)
- The period of amortization or accretion for debt securities generally extends from the purchase date to the maturity date unless other Topics apply (320-942-35-1).
- For purposes of the ASC 320-10-50-1 through 50-3 and 50-5 through 50-5C disclosures, 'financial institutions' includes banks, savings and loan associations, savings banks, credit unions, finance companies, and insurance entities (320-942-50-1).
- Disclosures must present prescribed major security types—equity securities segregated by industry type, entity size, or investment objective; U.S. Treasury/agency, state and political subdivision, foreign government, and corporate debt; residential and commercial mortgage-backed securities; collateralized debt obligations; and other debt obligations (320-942-50-2).
- Mutual funds that invest only in U.S. government debt securities may be shown separately rather than grouped with other equity securities (320-942-50-2A).
- The net carrying amount of debt securities must be disclosed in at least four maturity groupings (within 1 year, 1–5 years, 5–10 years, after 10 years), with securities lacking a single maturity date (e.g., mortgage-backed securities) either shown separately or allocated with the basis of allocation disclosed (320-942-50-3); public business entities must also disclose fair value by the same groupings (320-942-50-3A).
- The carrying amount of investment assets pledged as collateral for public funds, repurchase agreements, and other borrowings, if not otherwise disclosed under Topic 860, must be disclosed in the notes, and the notes must explain the institution's securities accounting policy including the basis for classification (320-942-50-4; 320-942-50-5).
- A regulator's general authority to require divestiture is not an automatic impairment of the ability to hold a security to maturity, though specific facts and circumstances may indicate the institution lacks that ability (320-942-55-1; 320-942-55-2).
For students. This is where bank and insurance securities-portfolio footnote disclosures come from—expect questions on the four maturity buckets and the required major security types. A common misunderstanding is that regulators' power to force a sale destroys held-to-maturity intent; 320-942-55-1 says the general authority alone does not, only specific facts and circumstances can.
