Depositary shares financial

"DEPOSITARY SHARES EACH REPRESENTING 1/1,000TH OF A SHARE"

Depositary shares are tradable certificates that represent a fractional piece of a larger security held by a third-party bank, like owning a slice of a single big pie instead of the whole pie. They let companies issue and investors buy smaller, more affordable portions of preferred stock or other instruments; holders usually receive proportional dividends and market pricing similar to ordinary shares, but may have limited voting rights and different liquidity or tax implications, which can affect income and resale value.

Fixed-to-Floating Rate financial

"FIXED-TO-FLOATING RATE NON-CUMULATIVE PREFERRED STOCK"

A fixed-to-floating rate is a type of loan or investment that starts with a fixed interest rate for a certain period, meaning the payments stay the same, then switches to a variable rate that can change over time based on market conditions. This matters because it offers the stability of fixed payments initially, but also the flexibility to benefit if interest rates drop later.

Non-Cumulative Preferred Stock financial

"NON-CUMULATIVE PREFERRED STOCK, SERIES I"

Preferred stock that pays a fixed dividend but does not require the company to make up missed payments later; if a dividend is skipped, shareholders lose that income permanently rather than accumulating a balance the company must repay. Investors care because this structure offers higher priority than common shares for payouts but less protection for dividend income, so it’s a trade-off between steady yield and the risk of permanent missed payments.

Prospectus Supplement regulatory

A prospectus supplement is an additional document provided alongside a company's main offering details, offering updated or extra information about a specific financial product being sold. It helps investors understand the latest terms, risks, and details of the investment, similar to how an update or revision clarifies or expands on original instructions, ensuring they have current and complete information before making a decision.
