(1) Under risk-based capital rules, CSC and CSB are also required to maintain additional capital buffers above the regulatory minimum risk-based capital ratios. As of June 30, 2023, CSC was subject to a stress capital buffer of 2.5%. In addition, CSB is required to maintain a capital conservation buffer of 2.5%. CSC and CSB are also required to maintain a countercyclical capital buffer above the regulatory minimum risk-based capital ratios, which was zero for both periods presented. If a buffer falls below the minimum requirement, CSC and CSB would be subject to increasingly strict limits on capital distributions and discretionary bonus payments to executive officers. At June 30, 2023, the minimum capital ratio requirements for both CSC and CSB, inclusive of their respective buffers, were 7.0%, 8.5%, and 10.5% for Common Equity Tier 1 Risk-Based Capital, Tier 1 Risk-Based Capital, and Total Risk-Based Capital, respectively.
N/A Not applicable.

Based on its regulatory capital ratios at June 30, 2023, CSB is considered well capitalized (the highest category) under its respective regulatory capital rules. There are no conditions or events since June 30, 2023 that management believes have changed CSB’s capital category.

At June 30, 2023, the balance sheets of Charles Schwab Premier Bank, SSB (CSPB) and Charles Schwab Trust Bank (Trust Bank) consisted primarily of investment securities, and the entities held total assets of $29.9 billion and $11.8 billion, respectively. Based on their regulatory capital ratios, at June 30, 2023, CSPB and Trust Bank are considered well capitalized under their respective regulatory capital rules.

Pursuant to the SEC’s Customer Protection Rule and other applicable regulations, Schwab had cash and investments segregated for the exclusive benefit of clients at June 30, 2023. The SEC’s Customer Protection Rule requires broker-dealers to segregate client fully-paid securities and cash balances not collateralizing margin positions and not swept to money market funds or bank deposit accounts. Amounts included in cash and investments segregated and on deposit for regulatory purposes represent actual balances on deposit. Cash and cash equivalents included in cash and investments segregated and on deposit for regulatory purposes are presented as part of Schwab’s cash balances in the condensed consolidated statements of cash flows.
