The only way your assets would not be refigured and could use 200DDB/HY for the AMT calculation is if they are not section 1250 property AND were placed in service before 1999. Any non-section 1250 property placed in service after 12/31/1998 is required to use the 150DDB/HY and then switch to the straight-line method in the first year that calculation would provide a larger deduction for the partner. This rule is slightly different if the partner of the LLC is an estate or trust, but only for assets placed in service before 1999.
