                        is the number of days in the taxable year after 
                        December 31, 2011, and the denominator of which

Summary: Amends the Internal Revenue Code to: (1) extend for one year the 100% bonus depreciation allowance for business assets, and (2) increase the amount of alternative minimum tax (AMT) credits that corporate taxpayers may elect to accelerate in a taxable year in lieu of claiming bonus depreciation.
