Key Terms

4 terms

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.

MasterCraft Boat Holdings, Inc. financial

"by and among MasterCraft Boat Holdings, Inc., a Delaware corporation"

par value financial

"MasterCraft Common Stock, par value $0.01 per share"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.

withholding taxes financial

"$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.
