There is some degree of uncertainty about what the prices for standard and superior materials will be
in the upcoming year. If many companies up the usage of superior materials, in an effort to boost their
S/Q ratings, there’s reason to expect that worldwide use of superior materials will exceed 50% of all
materials used in making athletic footwear, thereby resulting in (1) a 2.0% increase in the price of
superior materials for each 1% that the worldwide percentage use of superior materials exceeds 50%
and (2) a 0.5% decline in the price of standard materials for each 1% that the global usage of standard
materials falls below 50%. Shifting prices for standard and superior materials, which are not known in
advance, cause actual costs for materials to differ (up or down) from the projected materials costs
shown on the screen.
