the carrying forward period are the number of period you are still entitled to use any tax advantage such as the DTA. You can't carry on your DTA indefinitely, that what i understood. Let say this time is limited to 3 years. So if for any reason you can't use your DTA, and you are in year 2, you'll account for a valuation allowance. If somehow your time is extend to 4 more years, then you'll decrease your valuation allowance since the probablity of using it is getting high again
