B is corrent. The requirement is to determine the adjustment for adjusted current earnings (ACE) that will be used in the computation of Axel Corp.’s alternative minimum tax for 2012. The ACE adjustment is equal to 75% of the difference between ACE and pre-ACE alternative minimum taxable income (AMTI). The ACE adjustment can be positive or negative, but a negative ACE adjustment is limited in amount to prior years’ net positive ACE adjustments. For 2011, Axel had a positive ACE adjustment of ($500,000 — $450,000) x 75% = $37,500. For 2012, Axel’s ACE is less than its pre-ACE AMTI, leading to a tentative negative ACE adjustment of ($200,000 — $300,000) x 75% = ($75,000). However, this negative ACE adjustment is allowed only to the extent of $37,500, the amount of Axel’s net positive adjustment for prior years.
A is incorrect. A negative ACE adjustment is allowed only to the extent of the net positive adjustment for prior years.  
C is incorrect. A negative ACE adjustment is allowed only to the extent of the net positive adjustment for prior years. 
D is incorrect. A negative ACE adjustment is allowed only to the extent of the net positive adjustment for prior years.
