DURHAM, N.C. — An audit conducted by North Carolina Central University found employees charged unauthorized personal items to university credit cards in 2002 and 2003.

The public university in Durham yesterday refused to disclose the total amount of unauthorized charges, the number employees who made them, or their names.

NCCU officials say they need time to consult with an attorney because they're unsure whether the detailed information is public.

Before receiving a university credit card, an employee must sign an agreement limiting its use to business-related travel and expenses. N.C.C.U. employees are expected to pay monthly bills associated with their school-issued American Express cards.

Employees can then submit their statements and proof of payment to the university for reimbursement.

A university spokeswoman says no employee has been reimbursed for unauthorized, personal charges.

Also, no employee cards have been confiscated or canceled for violating the policy.
