Tan Corporation of Japan has two regional divisions with headquarters in Osaka and Yokohama. Selected data on the two divisions follow: Division Osaka Yokohama Sales $ 9,400,000 $ 24,000,000 Net operating income $ 752,000 $ 2,400,000 Average operating assets $ 2,350,000 $ 8,000,000 Required: 1. For each division, compute the return on investment (ROI) in terms of margin and turnover. 2. Assume that the company evaluates performance using residual income and that the minimum required rate of return for any division is 18%. Compute the residual income for each division.

1. Osaka ROI 32 %

Yokohoma ROI 30%

2.Osaka Residual income $329,000

Yokohoma Residual income $960,000

Explanation:

1. Computation for return on investment (ROI) in terms of margin and turnover.

Using this formula

ROI = Net operating income/Average operating assets

Let plug in the morning

Osaka ROI = 752,000/2,350,000

Osaka ROI =32 %

Yokohoma ROI = 2,400,000/$ 8,000,000

Yokohoma ROI =30%

Therefore for return on investment (ROI) in terms of margin and turnover is :

Osaka ROI 32 %

Yokohoma ROI 30%

2. Computation for the residual income for each division.

Using this formula

Residual income = Net operating income - Required return

Let plug in the formula

Osaka Residual income= 752,000 - (2,350,000*18%)

Osaka Residual income= 752,000-423,000

Osaka Residual income = $329,000

Yokohoma Residual income = 2,400,000 - ($8,000,000*18%)

Yokohoma Residual income = 2,400,000-1,440,000

Yokohoma Residual income= $960,000

Therefore the residual income for each division is:

Osaka Residual income $329,000

Yokohoma Residual income $960,000
