GDANSK, July 31 (Reuters) - Commerzbank's CBKG.DE Polish unit mBank MBK.WA posted on Thursday a 127% rise in second-quarter profit driven by a drop in provisions for the bank's Swiss franc mortgage portfolio and high net interest income.
Its net profit more than doubled to 959.4 million zlotys ($256.6 million) in the quarter against 422 million zlotys reported for the same period a year earlier. That exceeded analysts' average forecast for a profit of 933 million zlotys.
($1 = 3.7387 zlotys)
