Final answer:
Company Z's return on equity using year-end equity will be 100%.
Step-by-step explanation:
Company Z expenses the printer, which means it deducts the full cost of the printer (£300,000) in the year it was purchased. This will reduce the net income for the year compared to Company X, which only depreciates the printer over its useful life. To calculate Company Z's return on equity using year-end equity, we need to determine the net income for the year. Since Company Z expenses the printer, its net income will be lower than Company X. However, the book value of equity at the end of the year will remain the same for both companies, as the printer was expensed rather than depreciated.
Using the information provided, we can calculate Company Z's net income by subtracting the dividends and the change in equity from the beginning equity. The change in equity will be £0, as the printer was expensed. So, the net income for Company Z will be £10,000,000 - £0 - £0 = £10,000,000.
Now, we can calculate the return on equity for Company Z using the net income and the beginning equity. The return on equity formula is: Return on Equity = (Net Income / Beginning Equity) x 100%
Plugging in the values, we get: Return on Equity = (£10,000,000 / £10,000,000) x 100% = 100%
So, Company Z's return on equity using year-end equity will be 100%.
