(B) Sales. Sales by each controlled participant in the business activities in which covered intangibles are exploited may be used as an indirect basis for measuring its anticipated benefits. This basis of measurement will be more reliable to the extent that each controlled participant is expected to have a similar increase in net profit or decrease in net loss attributable to covered intangibles per dollar of sales. This circumstance is most likely to arise if the costs of exploiting covered intangibles are not substantial relative to the revenues generated, or if the principal effect of using covered intangibles is to increase the controlled participants' revenues (e.g., through a price premium on the products they sell) without affecting their costs substantially. Sales by each controlled participant are unlikely to provide a reliable basis for measuring benefits unless each controlled participant operates at the same market level (e.g., manufacturing, distribution, etc.).
