par value financial

"equivalent to a par value of US$ 7,961,386"

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.

nominal value financial

"average price equivalent to 99.87% of their nominal value"

Nominal value is the stated or face amount assigned to a financial instrument — for shares it’s the par value printed on the stock certificate, and for money or returns it can mean the number not adjusted for inflation. Think of it like a price tag on an item versus its buying power: the tag tells you the label, but not how much you can actually buy. Investors care because nominal values affect accounting, legal capital, dividend calculations and comparisons over time when inflation may distort real worth.
