Key Terms

3 terms

book entry financial

"common, book entry, Class B shares"

A book entry is an electronic record that shows who owns a share, bond or other financial asset without issuing a paper certificate, like keeping money in a bank account instead of carrying cash. It matters to investors because it makes buying, selling and proving ownership faster, cheaper and less risky—reducing lost or forged certificates and simplifying transfers and record-keeping for dividends, votes and tax reporting.

par value financial

"with a par value of Ps$. 1"

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.

Class B shares financial

"common, book entry, Class B shares"

Class B shares are one type of a company’s stock that carries a specific set of rights — often different voting power or dividend rules compared with other classes. For investors, that affects influence over company decisions and potential income: owning Class B might mean fewer or more votes per share or different claim on profits, like having a different seat at a decision table or a different slice of the payout pie.
