Key Terms

2 terms

par value financial

"Common shares, 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.

voting rights regulatory

"exercises control over the voting rights of the holding company"

Voting rights are the ability of shareholders to have a say in important company decisions, like choosing leaders or approving big changes. They matter because they give owners a voice in how the company is run, similar to how voters influence elections, ensuring the company acts in shareholders’ interests.
