Yes, MCL 208.1417(9)(d) provides in part:
"Loss adjustment" means the amount by which adjusted business income was
less than zero in any of the 5 tax years immediately preceding the tax year
for which eligibility for the credit under this section is being determined...
The Department will allow the use of a "loss adjustment" from a period prior
to the start of the MBT for purposes of computing the loss adjustment in
calculating the small business alternative credit. Therefore, in 2008, a
calendar year taxpayer could look at years 2003 through 2007.
