Samsung affiliates fined $206M for unfair business practice: Report

South Korea's antitrust regulator on Thursday said that it has decided to fine five affiliates of Samsung Group a combined 234.9 billion won ($206 million) for their alleged unfair business practice over an in-house cafeteria business.

The Korea Fair Trade Commission (KFTC) also said it will file complaints with the prosecution against Samsung Electronics Co. and its former executive Choi Gee-sung over alleged unfair support for Samsung Welstory Inc., the group's food service affiliate.

Samsung Electronics, Samsung Display and two other Samsung units are alleged to have unfairly supported Samsung Welstory since 2013 by allowing it to run their in-house cafeteria business for them, reports Yonhap news agency.

The regulator said Samsung Electronics and four other units, including Samsung Welstory, will face the largest-ever fine imposed for an unfair internal trading case.

Samsung Electronics, the group's crown jewel, will face a 101.2 billion-won fine, also the largest-ever one for a single company.

Established in 2013, Samsung Welstory is a wholly owned affiliate of Samsung C&T Corp., the group's de facto holding company. Lee Jae-yong, the apparent heir of Samsung Group, is the largest shareholder of Samsung C&T.

The commission said the four Samsung units helped Samsung Welstory continue to maintain high profitability by unfairly supporting labor and other costs.

The KFTC said Samsung Welstory has served as a "cash cow" for the group's founding family as large amounts of net profits by the cafeteria business affiliate were provided to Samsung C&T as dividends.

Internal trading is blamed here for allowing owner families of conglomerates to easily net large profits by having subsidiaries award lucrative contracts to each other, undermining the principle of fair competition.

Earlier this month, the KFTC rejected the Samsung affiliates' proposed measures to address their unfair business activity, including lowering the entry barrier for it's cafeteria business to non-affiliated firms.
