Example. Corp. X, a corporation to which section 593 applies, is a member of an affiliated group that files a consolidated return. For a particular taxable year, Corp. X has gross income of $1,000, and of this amount, $150 is an excess inclusion attributable to a residual interest that has significant value. Corp. X has $975 of allowable deductions for the taxable year. Corp. X must apply its allowable deductions first to offset the $850 of gross income that is not an excess inclusion, and then to offset the portion of its gross income that is an excess inclusion. Thus, Corp. X has $25 of taxable income ($1,000-$975), and that $25 is an excess inclusion that may not be offset by losses sustained by other members of the affiliated group.
