buy-back program financial

"Within the scope of our Company’s buy-back program"

A buy-back program is when a company uses cash to repurchase its own shares from the market or shareholders, reducing the total number of shares outstanding. It matters to investors because fewer shares can raise per-share earnings and ownership percentage—like cutting a pie into fewer slices so each slice is bigger—while also signaling management’s view of the company’s value and affecting cash available for other uses.

Nominal Value financial

"Nominal Value of Shares Subject to Transaction (TRY)"

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.

Ratio to Capital financial

"Ratio to Capital (%)"
