Performance Stock Units financial
"Each Performance Stock Unit ("PSU") represents a contingent right to receive one share"
Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.
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.

401(k) financial
"Common Stock ... nature_of_ownership: "by 401(k)""
A 401(k) is a type of retirement savings plan offered by employers that allows workers to set aside a portion of their paycheck before taxes are taken out. The money saved in a 401(k) can grow over time through investments, helping individuals build funds for their future retirement. It matters to investors because it provides a tax-advantaged way to save and invest for long-term financial security.
