In late 2017, the Justice Department asked Wells Fargo WFC to look into its wealth-management business due to allegations from whistleblowers from within the bank about its sales problem.The firm hired to conduct this independent investigation, Shearman Sterling, is the same firm that represented the Wells Fargo board on the sales-scandal disclosed in September 2016. In April 2017, they released a 113-page report that was a long-anticipated deep dive into the questionable sales conduct affecting as many as 3.5 million accounts that dated to 2002 and ultimately resulted in a 185 million regulatory penalty in September 2016. At this time, nothing is confirmed about what Sherman Sterling has discovered about WFCs wealth management division. According to the bank, the investigation is in preliminary stages and is about whether there have been inappropriate referrals or recommendations, including with respect to rollovers for 401k plan participants, certain alternative investments, or referrals of brokerage customers to the companys investment and fiduciary services business.WFC has continued to face a series of problems including:- The Federal Reserve announced an unprecedented enforcement action capping the banks assets. The Fed also said the bank would be replacing four members of its boards in 2018- Last year, Wells Fargo said it also improperly charged around 800,000 auto-loan customers and up to 110,000 mortgage customers. The bank has said it is in the process of refunding those customers more than 100 million- Wells Fargo also disclosed in the Thursday filing that it is reviewing fee calculations within certain fiduciary and custody accounts. The bank has found instances of incorrect fees applied to certain assets and accounts that resulted in overcharging customers, according to the filing- The Wall Street Journal reported in late 2017 that the bank had fired four FX bankers, and federal prosecutors opened an investigation of the FX operationOn a related note, Fed chairperson Jerome Powell conceded after an intense exchange with Sen. Elizabeth Warren D., Mass. that WFCs plans would be put in front of the Fed board for a vote instead of being determined solely by a low-ranking Fed official. As a response, WFC CEO Mr. Sloan said that while the problems may seem discouraging, he asked employees to remember that we are making significant progress in our work to build a better Wells Fargo, and we recognize that more challenges and more hard work lie ahead.  <response>: Whats the point of this article?
