BNP Paribas CFO Lars Machenil speaks with Bloomberg TV's Guy Johnson and Anna Edwards as the bank reported better-than-expected revenue and profit for the second quarter. "If you look at the cost of risk in our divisions, it is basically stable," he says. "What is that additional basis point coming from? It's because we took a prudent stand saying there is some geopolitical uncertainty and that allows us to take a generic provision for that uncertainty," Machenil adds.
