"Consists of 3,586 restricted stock units ("RSUs"). Each RSU represents the right to receive, at settlement, one share"

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

Cumulative Perpetual Preferred Stock financial

"8.625% Series A Cumulative Perpetual Preferred Stock"

A cumulative perpetual preferred stock is a share that acts like a long-lasting hybrid between a bond and a dividend-paying stock: it promises regular fixed payments that, if missed, accumulate and must be paid later before common shareholders get dividends, and it has no set maturity date. Investors care because it can provide steady, higher-priority income similar to interest, but with limited capital upside, sensitivity to interest rates, and the risk that payments can be delayed even though they continue to accrue.

Depositary Shares financial

"Depositary Shares - 8.375% B Cumulative Stock"

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.
