! Required information [The following information applies to the questions displayed below.) Wyalusing Industries has manufactured prefabricated houses for over 20 years. The houses are constructed in sections to be assembled on customers' lots. Wyalusing 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. Wyalusing designated the Fairmont Division as an investment center. Wyalusing 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 16 percent before income taxes. Fairmont's ROI has ranged from 19.7 to 22.9 percent since it was acquired. Fairmont had an investment opportunity in 20x1 that had an estimated ROI of 18 percent.
