JPMorgan CFO: We've found some cross-selling issues, but nothing 'systemic'

JPM CFO: Doing 'deep dive' probe of cross-selling

JPMorgan CFO Marianne Lake said Friday that her bank is conducting a "deep dive" into potential cross-selling issues.

"I've found no systemic issues," she said.

Lake, however, explained that "it's impossible to have zero defects," acknowledging that there have been some instances of cross-selling issues of their own.

Attentions are turned to the subject since Wells Fargo become the focus of intense criticism and multiple investigations as a result of a phony bank accounts scandal. That bank paid $185 million in penalties for opening roughly 2 million consumer deposit and credit card accounts without customer authorization.

Wells' John Stumpf retired Wednesday as chairman and CEO at the bank, which still faces a number of ongoing investigations by regulators, as well as private lawsuits.

On the JPMorgan earnings call, Lake said the bank is focused on developing "deep customer relationships," so cross-selling is an outcome, but not necessarily an objective.

JPMorgan announced Friday that it had easily topped expectations for its third-quarter results, saying it had seen strong loan growth.

The bank reported quarterly earnings of $1.58 per share on revenue of $25.51 billion. Analysts had expected earnings of $1.39 a share on about $24 billion in revenue, according to a consensus estimate from Thomson Reuters.
