Agreement and Plan of Merger regulatory

"The reported securities were disposed of pursuant to the terms of the Agreement and Plan of Merger"

An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.

par value $0.01 per share financial

"MasterCraft Common Stock, par value $0.01 per share and $2.43 in cash"

withholding taxes regulatory

"$2.43 in cash, without interest and less applicable withholding taxes"

Withholding taxes are amounts a payer or government takes out of payments — such as wages, interest, or dividends — before the recipient gets the money, functioning like a cashier keeping part of a bill to pay taxes on your behalf. For investors this matters because it reduces the cash they actually receive, affects net returns and yield calculations, and may require additional paperwork or treaty claims to recover or offset the withheld amount against final tax bills.
