The TFTC promulgated the Fair Trade Commission Guidelines on Handling Merger Filings, as amended, on July 7, 2014.  Highlights of the Amendment are summarized as follows: (1) for transactions involving a horizontal merger, the simplified procedure for merger filing is applicable where the aggregate market share of the parties is less than 25%, and the market share of one of the parties is less than 5%; or where the aggregate market share of the parties is less than 10 % notwithstanding that the aggregate market share of the top two competitors reaches 2/3, or that the aggregate market share of the top three competitors reaches 3/4; (2) “the probability of raising competitors’ costs” and “the probability of resulting in concerted actions” are added as factors to be considered in the assessment of the effects of restricting competition in vertical mergers; (3) “economic efficiency” is added as a factor to be considered in the assessment of overall economic benefits.  To satisfy the said economic efficiency factor, the efficiency must be that which may be proven to be realized within a short period of time, that which cannot be achieved by means other than the merger, and that which may reflect the interests of consumers.
