Samsung Electronics said Thursday that it decided to buy back its own shares worth one-point-eight trillion won.

The buyback, also known as a share repurchase, will begin Friday for a duration of three months.

Through the buyback, Samsung will purchase or retire 990-thousand common stocks and 230-thousand preferred stocks.

In October last year, the tech giant announced a buyback plan of its own special treasury stocks worth a total of eleven-point-three trillion won.

Three rounds have been completed through which nine-point-five trillion won worth of shares were repurchased, and the fourth and last rounds begin Friday.
