Suburban Lifestyles expanded into the precut housing market when it acquired Fairmont Company, one of its suppliers. In this market, various types of lumber are precut into the appropriate lengths, banded into packages, and shipped to customers lots for assembly. Suburban Lifestyles' management designated the Fairmont Division as an investment center. Suburban uses return on investment (ROI) as a performance measure with investment defined as average productive assets. Management bonuses are based in part on ROI. All investments are expected to earn a minimum return of 15 percent before income taxes. Fairmont's ROI has ranged from 24.6 to 27.8 percent since it was acquired.
