Stock Appreciation Rights financial

"One third of the Stock Appreciation Rights became exercisable"

Stock appreciation rights (SARs) are a form of employee compensation that give the holder the right to receive the increase in a company's stock price over a set baseline, paid in cash or shares, without having to buy the stock. For investors, SARs matter because they can create future cash outflows or share dilution and signal how a company rewards and motivates executives — similar to giving a bonus tied directly to how well the company’s stock performs.
