Detailed Answer
(c) The requirement is to determine the exempt portion
of Rona Corp.’s alternative minimum taxable income (AMTI). A
corporation is allowed an exemption of $40,000 in computing its
AMTI. However, the $40,000 exemption is reduced by 25% of
the corporation’s AMTI in excess of $150,000. Here, the amount
of exemption is $40,000 � [($200,000 � $150,000) � 25%] =
$27,500.
