Phantom Stock Units financial

"Security title listed as "Phantom Stock Units" with a one-to-one stock conversion."

Phantom stock units are company promises that pay a cash or stock-equivalent award tied to the firm’s share price or value growth, but they do not issue actual shares. Think of them as a bonus check that moves with the stock like a mirror rather than handing over an ownership slice. Investors care because these awards can affect a company’s future cash obligations, executive incentives and reported expenses without causing share dilution.

Non-Employee Director Deferred Compensation Plan financial

"Grant represents annual director compensation under the Olin Corporation Non-Employee Director Deferred Compensation Plan."

Grant, award, or other acquisition financial

"Transaction code description notes a "Grant, award, or other acquisition" of units."
