Cash Settled Restricted Stock Units financial
"The security title includes Cash Settled Restricted Stock Units with underlying common stock."
Cash-settled restricted stock units are employee compensation promises that mirror the value of company shares but pay out in cash instead of delivering actual stock once the units vest. Think of them as a future paycheck tied to the company’s share price that is paid after time or performance conditions are met. Investors watch them because they create future cash obligations for the company and avoid share dilution, both of which can affect earnings, cash flow and per-share metrics.
Disposition to issuer financial
"Transaction code D is described as Disposition to issuer for common stock."

"Transaction code M is described as Exercise or conversion of derivative security."
economic equivalent of one share financial
