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.
