Discount Outlet has net income of $389,100, a profit margin of 2.8 percent, and a return on assets of 8.6 percent. What is the c
Ratling [72]

An efficiency ratio known as the capital intensity ratio provides valuable insight into a company's financial situation.

Capital Intensity Ratio = Total Assets/Total Revenue

Return on assets = Net income/Total Assets

Total Assets = Net income/Return on Assets= $389,100/0.086

Total Revenue = Net income/Net Profit Margin = $389,100/0.028

Capital intensity ratio = ($389,100 /0.086) / ($389,100 / 0.028) =0.33

This ratio reveals how much capital or other resources a company has to have in order to make single dollar in sales. This ratio is the inverse of the asset turnover ratio, making it simple to calculate the capital intensity ratio if you already know the asset turnover ratio. For all capital-intensive firms, we require a good or higher capital intensity ratio. A company that invests a significant amount of capital in its manufacturing process is said to be capital-intensive. E.g., Power generating facilities. A company that has made significant investments in assets to generate income has a high capital intensity ratio (CIR). A company with a low CIR is able to produce larger revenues while owning fewer assets. As a result, businesses can use this ratio to modify their capital budgeting and planning.

Nadya [2.5K]

Answer:

The 9,300 should Allegheny report as Uncollectible Accounts Expense on its Year 2 income statement

Explanation:

The non-collectible accounts expenses on its Year 2 income statement is shown below:

= Ending balance + write off balance - opening balance

= $6,000 + $7,200 - $3,900

=$9,300

The accounts receivable is not to be considered because we have to find out the uncollectible accounts expense, so the account receivable balance should not be taken in the computation part.

Hence, the 9,300 should Allegheny report as Uncollectible Accounts Expense on its Year 2 income statement
