Required information (The following information applies to the questions displayed below.) Blackwood Industries manufactures die machinery. To meet its expansion needs, it recently (2017) acquired one of its suppliers, Delta Steel. To maintain Delta's separate identity, Blackwood reports Delta's operations as an investment center. Blackwood monitors all of its investment centers on the basis of return on investment (ROI), Management bonuses are based on ROI, and all investment centers are expected to earn a minimum 10% return before income taxes. Delta's ROI has ranged from 14% to 18% since 2017. The company recently had the opportunity for a new investment that would have yielded a 13% ROI.

The division's operating assets were $17,600,000 at the end of 2019, a 6% increase over the 2018 year-end balance.
