principal accounting officer financial

"In this role, Mr. Stringham will serve as the Bank's principal accounting officer"

The Principal Accounting Officer is the person responsible for making sure a company's financial records are accurate and follow the rules. They play a key role in preparing financial reports that show how well the company is doing. This helps investors, managers, and regulators trust the company's financial information.

Non-Cumulative Perpetual Preferred Stock financial

"Depositary Shares each representing a 1/40th ownership interest in a share of Series A Floating-Rate Non-Cumulative Perpetual Preferred Stock"

Non-cumulative perpetual preferred stock is a type of investment that pays a fixed dividend forever, without a set end date. If the company skips some dividends in a year, you don’t get that money later, and it’s gone forever. It matters because investors get regular income but may miss out if the company faces financial trouble.

Inline XBRL technical

"Cover Page Interactive Data File - the cover page XBRL tags are embedded within the Inline XBRL document"

Inline XBRL is a file format for financial filings that embeds machine-readable data tags directly inside the human-readable report, so the same document can be read by people and parsed by software. For investors it makes extracting, comparing and verifying financial numbers faster and more reliable—like a grocery list where each item also has a barcode—reducing manual errors and speeding up analysis.

Regulation S-K regulatory

"There are no transactions involving Mr. Stringham that would require disclosure under Item 404(a) of Regulation S-K"

A set of U.S. Securities and Exchange Commission rules that tell public companies which narrative and qualitative details must be disclosed in filings, such as risk factors, management discussion, executive pay, legal proceedings and business description. Think of it as a standardized checklist or blueprint that ensures investors get the same types of background information from every company so they can compare risks, management quality and strategy before making investment decisions.
