A computer glitch at PNC Financial (PNC) last week delayed overnight processing for some customer transactions.

The glitch occurred overnight on Thursday, Jan. 2, affecting customers in markets including Louisville, Philadelphia, Northwest Pennsylvania, Northeast Pennsylvania and Delaware, according to PNC spokeswoman Marcey Zwiebel. Zwiebel said that she did not know how many PNC clients were impacted by the glitch.

PNC corrected the delayed transactions on Friday to reflect posting or payment dates of Thursday.

"All transactions from Friday have since been processed normally, so the issue is behind is," Zwiebel said in an email.
