For many years, Miner Industries has manufactured prefabricated garden sheds where the sheds are constructed in sections to be assembled on customers$$ property. The company expanded into the pre$-$fabricated shed market when it acquired V$-$Shed Company. V$-$Shed pre$-$cuts various types of lumber into the appropriate lengths, packages them, and ships the product to customers for assembly. Miner decided to maintain V$-$Shed$$s separate identity and, thus, established the V$-$Shed Division as an investment center of Miner.

Miner uses return on average investment $($ROI$)$ as a performance measure, with the investment defined as $$operating assets employed.$$ All investments in operating assets are expected to earn a minimum return of $18\%$ before income taxes. V$-$Shed$$s ROI has ranged from $21\%$ to $24\%$ since it was acquired.

V$-$Shed$$s operating statement for the year just ended is presented below. The division$$s $$operating assets employed$$ were $$11,550,000$ at the end of the year, a $5\%$ increase over the balance at the end of the previous year.
