Table 35: Investment Securities Summary (a)(b)

(a) At June 30, 2024, the accrued interest associated with our held to maturity and available for sale portfolios totaled $268 million and $252 million, respectively. The comparable amounts at December 31, 2023 were $281 million and $144 million, respectively. These amounts are included in Other assets on the Consolidated Balance Sheet.

(b) Credit ratings represent a primary credit quality indicator used to monitor and manage credit risk. Of our total securities portfolio,97% were rated AAA/AA at both June 30, 2024 and December 31, 2023.

(c) Amortized cost is presented net of allowance of $88 million for securities available for sale, primarily related to non-agency commercial mortgage-backed securities, and $5 million for securities held to maturity at June 30, 2024. The comparable amounts at December 31, 2023 were $86 million and $6 million, respectively.

(d) Held to maturity securities transferred from available for sale are included in held to maturity at fair value at the time of the transfer. The amortized cost of held to maturity securities included net unrealized losses of $3.8 billion at June 30, 2024 related to securities transferred, which are offset in AOCI, net of tax. The comparable amount at December 31, 2023 was $4.2 billion.

The fair value of investment securities is impacted by interest rates, credit spreads, market volatility and liquidity conditions. Securities available for sale are carried at fair value with net unrealized gains and losses included in Total shareholders’ equity as AOCI, unless credit-related. Net unrealized gains and losses are determined by taking the difference between the fair value of a security and its amortized cost, net of any allowance. Securities held to maturity are carried at amortized cost, net of any allowance. Investment securities at June 30, 2024 included $151 million of net unsettled purchases that represent non-cash investing activity, and accordingly, are not reflected on the Consolidated Statement of Cash Flows. The comparable amount for June 30, 2023 was $197 million of net unsettled purchases.

The PNC Financial Services Group, Inc. –Form 10-Q 47

We maintain the allowance for investment securities at levels that we believe to be appropriate as of the balance sheet date to absorb expected credit losses on our portfolio. At June 30, 2024, the allowance for investment securities was $93 million and primarily related to non-agency commercial mortgage-backed securities in the available for sale portfolio. The comparable amount at December 31, 2023 was $92 million. See Note 1 Accounting Policies in our 2023 Form 10-K for a discussion of the methodologies used to determine the allowance for investment securities.

At June 30, 2024, AOCI included pretax losses of $285 million from derivatives that hedged the purchase of investment securities classified as held to maturity. The losses will be accreted to interest income as an adjustment of yield on the securities.

Table 36 presents the gross unrealized losses and fair value of securities available for sale that do not have an associated allowance for investment securities at June 30, 2024 and December 31, 2023. These securities are segregated between investments that had been in a continuous unrealized loss position for less than twelve months and twelve months or more, based on the point in time that the fair value declined below the amortized cost basis. All securities included in the table have been evaluated to determine if a credit loss exists. As part of that assessment, as of June 30, 2024, we concluded that we do not intend to sell and believe we will not be required to sell these securities prior to recovery of the amortized cost basis.
