Market Dominant Position.

Section 27

SEC. 27. Market Dominant Position. – In determining whether an entity has market dominant position for purposes of this Act, the Commission shall consider the following: (a) The share of the entity in the relevant market and whether it is able to fix prices unilaterally or to restrict supply in the relevant market; (b) The existence of barriers to entry and the elements which could foreseeably alter both said barriers and the supply from competitors; (c) The existence and power of its competitors; (d) The possibility of access by its competitors or other entities to its sources of inputs; (e) The power of its customers to switch to other goods or services; (f) Its recent conducts; and (g) Other criteria established by the regulations of this Act. There shall be a rebuttable presumption of market dominant position if the market share of an entity in the relevant market is at least fifty percent (50%), unless a new market share threshold is determined by the Commission for that particular sector. The Commission shall from time to time determine and publish the threshold for dominant position or minimum level of share in the relevant market that could give rise to a presumption of dominant position. In such determination, the Commission would consider the structure of the relevant market, degree of integration, access to end-users, technology and financial resources, and other factors affecting the control of a market, as provided in subsections (a) to (g) of this section. The Commission shall not consider the acquiring, maintaining and increasing of market share through legitimate means not substantially preventing, restricting, or lessening competition in the market such as but not limited to having superior skills, rendering superior service, producing or distributing quality products, having business acumen, and the enjoyment and use of protected intellectual property rights as violative of this Act.
