Plans announced Tuesday by Gov. Mike Easley to deal with a $900 million state budget shortfall prompted the estimates.
UNC-Chapel Hill's share of the cuts could reach more than $15 million.
Easley announced Tuesday he would cut funds to most state agencies by an additional 3 percent -- on top of a 4 percent reversion in October. But the governor exempted education agencies from the 3 percent cut, instead requesting that the UNC system return an additional $21.1 million, a budget cut of about 1.5 percent.
"We've asked them to come forward with a significant amount of funds that they contribute without harming classroom instruction," Easley said. "The universities and community colleges have done their part."
In October, UNC-system officials reverted 2.7 percent of their budget, about $43 million, to the state because of dismal revenue projections. In addition to the $21.1 million cut, Easley made the October reversion an official cut.
As a result, the UNC system will lose a total of $64 million from this year's operating budget and $51 million slated to fund construction.
Jeff Davies, UNC-system vice president of finance, said system officials hope to decide by today how to distribute the $21.1 million cut among the 16 campuses, basing their decision partly on overall state funding.
If budget cuts are allotted proportionately, UNC-CH's share would be about $5 million, bringing UNC-CH's total budget cut for the fiscal year to more than $15 million.
Davies said every effort would be made to shield instruction from cuts. "The plan is to continue to try to protect classroom instruction," he said. "It's difficult to revert money at this point in the year."
