Answer:
I. Residual Income:
Snow division
Residual Income = Operating income - (Total assets × Target rate of return)
Residual Income = $990,000 - ($4,400,000 * 15%)
Residual Income = $330,000
Thus, The residual income of the snow division is $330,000.
Non-snow division
Residual Income = Operating income - (Total assets × Target rate of return)
Residual Income = $1,512,000 - ($6,300,000 * 15%)
Residual Income = $567,000
Thus, The residual income of the non-snow division is $567,000
ii. The divisions have positive residual incomes, that is, both the divisions are earning income more than the target return on the investments.
iii. The results are consistent with the return on investment calculations of both the divisions.
