Q. Example on completion method?

Assume that by the end of the first year (2010) the company had incurred actual construction costs of USD 30 million. These costs are 75 percent of the total approximate construction costs (USD 30 million/USD 40 million = 75 percent). In the percentage-of-completion method the firm would use the 75 percent figure to assign revenue to the first year. In 2011 it acquires another USD 6 million of construction costs. In 2012 it earns the final USD 4 million of construction costs. The amount of revenue to assign to every year is as follows

The sum of gross margin to recognize in each year is as follows

This company would subtract other costs incurred in the accounting period such as general and administrative expenses from gross margin to determine net income. For example assuming general and administrative expenses were USD 100000 in 2010 net income would be (USD 3000000 - USD 100000) = USD 2900000.
