The management of Wells Fargo (WFC_) designed the previously indeterminate cost of complying with new limits on debit-card interchange fees.

CFO Howard Atkins while attending a conference call on Friday, pointed out that the new rule may drain as much as two hundred and fifty million dollars from Wells' top line in each quarter in the initial stage as long as the bank can't implement new fees to make up the difference. But Atkins added several warnings because the interchange provision has not been implemented yet.

It's still being mooted and they would suggest there's a varied range of possible outcomes, there won't be any impact if this regulation is not implemented, stated Atkins further.

The supposedly termed "Durbin amendment," which was named after the senator, who put it into the financial reform bill, faced wide opposition from the financial industry, but the same bill was adored by merchants who will gain advantage from it. TCF Financial (WFC), whose income will be most exposed for the interchange fee restrictions, has filed a case against the Federal Reserve for preventing its implementation.

Atkins made came up with these comments while addressing a conference call of analysts for discussing Wells Fargo's fourth-quarter results. The bank based in San Francisco reported earnings which kept parity with Wall Street expectations, having better credit on its consumer selection. Its growth seen in wholesale banking and wealth management had helped to boost results.

Wells earned in the tune of $3.4 billion, or sixty one cents per share during the period that ended on Dec. 31, which is a rise of twenty one percent from the corresponding quarter of the previous year. Revenue generated in the tune of twenty one and a half billion dollars, a decline from the earlier year's period but up from the third quarter.
