The formula for the return on assets is calculated by dividing the net income by the total average assets. The profit margin and total asset sales can also be represented as a consequence of this ratio. For the calculation of the total asset return, either formula may be used.

bixtya [17]

a) With Lake's 60% controlling interest in Boxwood, the total income tax expense reported on a consolidated income statement for this period is $99,023 ($471,540 x 21%).

b)  With Lake's 60% controlling interest in Boxwood, the total amount of income taxes payable for the current year is $101,400 ($363,000 + $120,000) x 21%.

c)  With Lake's 90% controlling interest in Boxwood, the amount of income tax expense to be reported on the consolidated income statement for the year is $97,820 ($465,810 x 21%).

<h3>What is controlling interest?</h3>

Controlling interest exists when a company or an individual owns more than 50% of the shareholdings of another company.  This gives the investor shareholder a majority voting share to influence decisions of the subsidiary company.

<h3>Data and Calculations:</h3>

                                    Lake        Boxwood

Income reported    $363,000    $120,000

Dividend paid             60,000          5,000

Dividend income          3,000 ($5,000 x 60%)

Increase in intra-entity gross profits = $19,100 ($41,500 - $22,400).

Excludable intra-entity gross profits = $11,460 ($19,100 x 60%).

Consolidated Income = $471,540 ($363,000 + $120,000 - $11,460)

Excludable intra-entity gross profits = $17,190 ($19,100 x 90%).

Consolidated Income = $465,810 ($363,000 + $120,000 - $17,190)
