3 terms

book-entry financial

"repurchased book-entry common shares"

A book-entry is an electronic record that shows who legally owns a share, bond or other security instead of a paper certificate. Think of it like a bank ledger entry that tracks ownership and transfers; it makes buying, selling, dividend payments and ownership checks faster, cheaper and less risky for investors because nothing physical needs to be moved or stored.

average daily trading volume financial

"25% of the average daily trading volume"

The average daily trading volume is the typical number of shares or units of a security that change hands each trading day, calculated over a set period. It tells investors how active a market is—like average traffic on a road—so higher volume usually means easier, faster trades and smaller price swings when buying or selling, while low volume can make orders harder to fill and cause bigger price moves.

par value financial

"a par value of ARS $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.
