WARSAW, Oct 5 (Reuters) - Poland's Alior Bank has increased the estimate of cost of credit vacations for mortgage holders that will negatively impact its third quarter results to 502 million zloty ($102.61 million), the bank said on Wednesday.

The estimate

adds 36 million zloty to the assessment released in July based on the assumption that 69% of mortgage holders entitled to participate in the program will do so.
