请问operating profit 是怎么计算出来的呢？

问题如下：

Based on the information below, calculate the Return on Invested Capital (ROIC) for the year 20X5. Values in each column are as of the end of the period. Assume an operating profit of 4,800 and a tax rate of 22% in Year 20X5.

The ROIC for year 20X5 is closest to:

选项：

A.

15.3%

B.

16.5%

C.

17.2%

解释：

To find the ROIC for the year 20X5, follow these steps:

1. Calculate Net Operating Profit After Taxes (NOPAT):

Operating Profit: 4,800

Tax Rate: 22%

NOPAT = Operating Profit × (1 - Tax Rate)

NOPAT = 4,800 × (1 - 0.22) = 4,800 × 0.78 = 3,744

2. Calculate Invested Capital:

Invested Capital = Long-term Debt + Share Capital

Invested Capital (20X5) = 12,000 + 13,100 = 25,100

Invested Capital (20X4) = 11,200 + 12,600 = 23,800

Average Invested Capital = (Invested Capital (20X5) + Invested Capital (20X4)) / 2

Average Invested Capital = (25,100 + 23,800) / 2 = 24,450

3. Calculate ROIC:

ROIC = NOPAT / Average Invested Capital

ROIC = 3,744 / 24,450 = 0.1532 = 15.32%
