Consider two industries, each comprising ten firms. In industry A, the largest firm has a market share of 49 percent. The next three firms have market shares of 7 percent each, and the remaining six firms have equal shares of 5 percent each. In industry B, the top four firms share the bulk of the market with 19 percent apiece. The next largest firm accounts for 14 percent, and the smallest five firms equally split the remaining 10 percent of the industry.
