Members of the association vary in the degree of market share that they possess in their respective areas. The range is from 1.5% to 16%, with the average being approximately 6%. While it is difficult to compare these figures with the market shares of larger regional and national chains because of the absence in the record of accurate statistics for these chains, there is much evidence in the record that Topco members are frequently in as strong a competitive position in their respective areas as any other chain. The strength of this competitive position is due, in some measure, to the success of Topco-brand products. Although only 10% of the total goods sold by Topco members bear the association's brand names, the profit on these goods is substantial and their very existence has improved the competitive potential of Topco members with respect to other large and powerful chains.
It is apparent that from meager beginnings approximately a quarter of a century ago, Topco has developed into a purchasing association wholly owned and operated by member chains, which possess much economic muscle, individually as well as cooperatively.
