Stock Appreciation Rights financial
"Stock Appreciation Rights granted pursuant to the Plan in exempt transactions under Rule 16b-3."
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.
Performance Earned Restricted Stock financial
"Includes an aggregate of 6,061 unvested restricted shares of Common Stock and 5,540 shares of Common Stock, issued as Performance Earned Restricted Stock."
Rule 16b-3 regulatory
"Stock Appreciation Rights granted pursuant to the Plan in exempt transactions under Rule 16b-3."
Rule 16b-3 is a Securities and Exchange Commission regulation that exempts certain routine, pre-approved transactions by company insiders from automatic liability for short-term trading profits. It acts like a safe harbor: if an insider follows a formal plan or the board approves specific transactions in advance, profits from buying and selling company stock within six months are not automatically reclaimed. Investors care because the rule clarifies when insider trades are permissible and reduces uncertainty about potential clawbacks.
401(k) Trust and Plan financial
"Approximate number of shares of Common Stock held ... in the account ... by Fidelity Trust Management Company, as Trustee of the RPM International Inc. 401(k) Trust and Plan."
tax obligations financial
"the Reporting Person disposed of 748 shares back to the issuer to satisfy tax obligations of the Reporting Person."
