 Expect fireworks in Washington on Tuesday morning. That’s when John Stumpf, the chairman and chief executive officer of Wells Fargo, is expected to appear in front of the Senate Banking Committee to answer questions about how, exactly, the corporate culture at his bank went so awry that employees opened an estimated 2 million bank and credit card accounts for customers without their permission. 
 
 Helaine Olen Helaine Olen is a former columnist for Slate and co-author of The Index Card. She was the host of the Slate Academy series the United States of Debt. 
 
 While the outlines of the situation at Wells Fargo have been known since a Los Angeles Times investigation in late 2013, few in the public or on Capitol Hill were worked up about or even aware of the problem until earlier this month, when the Consumer Financial Protection Bureau announced $185 million in penalties against the bank. The money will be split between the CFPB, the federal Comptroller of the Currency, and the Los Angeles City Attorney’s Office. Wells Fargo, which did not cop to or deny the allegations, also agreed to pay full restitution to the victims of the scam and says it’s already refunded $2.5 million.

 “I’ve got a lot of questions for that man,” Sen. Elizabeth Warren, a member of the banking committee and a harsh critic of wrongdoing in the financial industry, said on Bloomberg Television last week. No kidding! Slate also has a lot of questions for Stumpf—and we hope that Tuesday’s hearing includes at least some of these ones. 
 
 Do you believe that the problems at Wells Fargo went beyond a few rogue employees? 
 
 Wells Fargo has long had a reputation in the banking industry for outsize success in cross-selling. Have a Wells Fargo checking account? Then you need a Wells Fargo credit card! And a mortgage! And another checking account! To make all of these cross-sales, the bank set aggressive sales goals for its employees. Many former employees report that managers threatened to discipline or fire them if they didn’t meet the goals. And Wells Fargo knew there were issues. The bank conducted at least three internal investigations, the first in 2012, a year before the Los Angeles Times published its reporting, in an attempt to stop employees from opening sham accounts, which it must have known was a consequence of those insane goals. Nonetheless, even last week, Stumpf said that the bankers and frontline workers who engaged in the fraud refused to “put customers first” and didn’t “honor” Wells Fargo’s “vision and values.” 
 
 Is it really possible for thousands of low-level bank employees to thwart the will of senior management for years?

 The CFPB’s settlement with Wells Fargo covers the period between May of 2011 to the settlement date of Sept. 8, 2016. Wells Fargo says it’s fired more than 5,300 employees—somewhere between 1 and 2 percent of its entire workforce—as a result of the scandal. The New York Times and the Wall Street Journal reported that during this period the bank instituted trainings and subjected employees to lectures designed to knock out the fraudulent behavior. It also made some changes to the bonus system and beefed up internal compliance. But, again, many claim that supervisors continued to push employees to make the aggressive sales goals. So what values weren’t the fired employees honoring? 
 
 Why did Carrie Tolstedt, the head of community banking at Wells Fargo, announce her retirement earlier this year and receive a goodbye package worth an estimated $125 million? 
 
 Tolstedt was the executive responsible for oversight of all Wells Fargo branches, which is where the action took place. The announcement that Toldstedt, who is 56, planned to exit the bank came as a bit of a surprise. No reason was given at the time for her decision, though a bank spokeswoman subsequently said it was unrelated to the ongoing investigation. She was highly regarded by many both inside and outside the industry. Fortune magazine counted her as one of the “50 Most Powerful Women in Business.” In the news release the bank put out announcing Tolstedt’s retirement, Stumpf praised her, saying she was “one of our most valuable Wells Fargo leaders, a standard-bearer of our culture, a champion for our customers, and a role model for responsible, principled and inclusive leadership.” And yet during Toldstedt’s tenure as the senior executive responsible for bank branch management and performance, the fraud persisted and the sales goals that caused it were never rolled back. Meanwhile, Fortune reports, “Tolstedt was regularly praised for her unit’s ability to get customers to open numerous accounts. For a number of years, Wells Fargo’s proxy statement, which details executive pay, cited high ‘cross-selling ratios’ as a reason that Tolstedt had earned her roughly $9 million in annual pay.” 
 
 Will Wells Fargo attempt to recoup any of Tolstedt’s goodbye package or other payments?

 In a letter released last week, Warren and four other Democratic senators—Sherrod Brown, Jack Reed, Robert Menendez, and Jeff Merkley, all also members of the Senate Banking Committee—asked whether Tolstedt’s payday would be clawed back and pointed out that Wells Fargo’s own governance rules say that the company can demand payback for payments received as a result of false information, misconduct, or negligent behavior. In a response received on Monday, the company said this call will be made by the bank’s board of directors. Stumpf, in addition to serving as the company’s CEO, is also chairman of its board. 
 
 Will Wells Fargo attempt to claw back all or part of performance bonuses of other senior employees, including Stumpf's? 
 
 Even if Wells Fargo finds fault in the C-suite, doesn’t Tolstedt report to someone? Well, yes, she reports to CEO Stumpf. And what’s his pay? Stumpf earned $19 million last year, including a $10 million performance bonus. In fact, between 2012 and 2015, he collected $155 million in stock options related to performance bonuses, according to the Institute for Policy Studies, which calculated the value of stock options, bonuses, salary, and other compensation. 
 
 Did the lower-level people fired by Wells Fargo for their part in this scandal receive settlements, too? If so, how much did they receive?

 Because it’s worth noting that according to Glass Door, the typical Wells Fargo teller earns a base pay of $12 an hour, and a personal banker a little less than $40,000. These are the people Stumpf now blames for the endemic culture of fraud at the bank. 
 
 The Los Angeles City’s Attorney’s office first filed suit against Wells Fargo for this activity in the spring of 2015. The federal government also began looking into the bank later in the year. Why wasn’t this disclosed in corporate filings with the Securities and Exchange Commission? 
 
 Despite the internal probes, newspaper investigations, and government interest in the fraudulent sales practices at Wells Fargo, the bank continued to boast of its cross-selling prowess in its annual reports, reporting numbers that authorities challenged. Nonetheless, bank executives deemed none of this worthy of disclosing as a material fact in SEC filings. No doubt holders of Wells Fargo stock would disagree. Since authorities announced the $185 million settlement on Sept. 8, the stock price has dropped by almost 8 percent. 
 
 Will Wells Fargo continue to fight victims of this scheme who attempt to take them to court?

 Even as Wells Fargo conducted multiple investigations that found evidence of fraud at the bank, bank officials aggressively fought back against people who attempted to get restitution via the courts. Incredibly, courts ruled the mandatory arbitration agreements customers sign when doing business with Wells Fargo also cover accounts they did not authorize and were opened without their permission. Nonetheless, lawyers are now circling. Last week, a lawsuit was filed in Utah against the bank, seeking restitution for everything from actual financial harm to mental anguish as a result of the fraud. Lawyers are seeking class-action status. 
 
 Will Wells Fargo continue to stonewall victims who say they suffered significant financial losses because of the actions of their employees? 
 
 Latina singing star Ana Barbara claims she was the victim of identity theft. In a lawsuit filed this summer, she alleges that Wells Fargo employees opened multiple accounts and credit lines in her name, costing her more than $400,000. When she sought restitution, she says the bank would only give her $250,000, saying she waited too long to notify them of the missing funds and fraudulent activity. 
 
 What do you know about damage to the credit records and scores of customers? 
 
 Wells Fargo customers are beginning to surface with tales of credit-report harm. New Jersey mom Linda Edwards reported last week that someone—likely a bank employee—opened a credit card in her teenage daughter’s name. That someone then ran up charges on that card he or she did not pay. Her daughter’s credit record was damaged. Wells Fargo eventually refunded the fees it charged, but “they never addressed the identify theft, forgery, or fraud,” Edwards said, instead attempting to pin the blame for the unpaid bill on her daughter. This despite the fact the girl never applied for the card or had it in her possession. 
 
 In a phone call with reporters on Friday, California Rep. Brad Sherman said he would ask the CFPB to determine if any Wells Fargo customers' credit records or scores suffered damage as a result of the wide-scale fraud. Even without full-scale identity theft, it certainly sounds like a reasonable supposition. Many consumers racked up fees and penalties on the accounts they did not authorize and often did not know about. Even multiple inquiries for credit can result in a temporary lowering of one’s credit score. If a customer was seeking any other loan, it’s possible they paid higher interest rates as a result of Wells’ actions without even knowing the reason why. 
 
 Has there been any attempt to quantify how many customers succumbed to pressure from bank employees and signed on for bank products they did not need or even truly want? Will Wells Fargo attempt to track these customers down and make restitution to them, even though they don’t all seem to be part of the settlement with the CFPB? 
 
 On Reddit, one person claiming to be a former Wells Fargo banker explained how fellow employees conned existing customers into signing up for less than necessary services by falsely claiming they needed separate checking accounts for online shopping or separate debit cards for every signer on their business checking or savings account. The Los Angeles Times investigation also reported on this sort of employee behavior, claiming, for instance, that one supervisor caught her underlings convincing a homeless woman to open and pay fees on half a dozen Wells accounts. No surprise, others are coming forward to complain of similar treatment. Frank Ahn, a Los Angeles laundromat and check-cashing business owner, told Bankrate.com about Wells Fargo bankers who repeatedly told him to open multiple checking and savings accounts for his establishments, promising these would be no-fee accounts. They were not. It’s also possible—make that likely—more than a few people gave in to badgering and signed up for a credit card they didn’t need or really want. 
 
 This is not the first allegation of fraudulent activities at Wells Fargo in the past decade, nor is it the first settlement. Do you believe Wells Fargo might need to re-examine its culture and values? 
 
 In April of this year, Wells Fargo agreed to a $1.2 billion settlement with the federal government for misrepresenting the risk posed by certain mortgages during the housing bubble run-up (to be fair, before Stumpf was appointed CEO) so they could insure them through the Federal Housing Administration. In 2012, there was another housing-bubble settlement, this one on accusations Wells Fargo steered minority buyers to subprime loans during the go-go years even when they were qualified for mortgages with better financial terms. 
 
 Investors suffered too. Earlier this year, a unit at the bank was charged with fraud by the SEC, who claimed the bank did not reveal vital details to investors in a bond offering for baseball player Curt Schilling’s failed 38 Studios venture. Also earlier this year, Florida’s American Seminole tribe sued the bank for mismanaging a trust, claiming it lost $100 million to secretive fees fraudulently imposed on its funds by Wells Fargo. And in 2014, there was yet another settlement, this one for pushing risky investments between 2006 and 2008 on pension funds seeking more conservative strategies. 
 
 Student loans are also a problem spot. Last month, Wells Fargo agreed to pay $4.1 million to settle charges levied by the CFPB that it tacked illegal fees onto the accounts of some student loan borrowers. A deal to market student loans with online shopping giant Amazon unraveled this summer, after a number of elected officials expressed concern the plan could be “deceptive.” 
 
 Why do you still have a job? ||||| Everyone hates paying bank fees. But imagine paying fees on a ghost account you didn't even sign up for. 
 
 That's exactly what happened to Wells Fargo customers nationwide. 
 
 On Thursday, federal regulators said Wells Fargo (WFC) employees secretly created millions of unauthorized bank and credit card accounts -- without their customers knowing it -- since 2011. 
 
 The phony accounts earned the bank unwarranted fees and allowed Wells Fargo employees to boost their sales figures and make more money. 
 
 "Wells Fargo employees secretly opened unauthorized accounts to hit sales targets and receive bonuses," Richard Cordray, director of the Consumer Financial Protection Bureau, said in a statement. 
 
 Wells Fargo confirmed to CNNMoney that it had fired 5,300 employees over the last few years related to the shady behavior. Employees went so far as to create phony PIN numbers and fake email addresses to enroll customers in online banking services, the CFPB said.

 The scope of the scandal is shocking. An analysis conducted by a consulting firm hired by Wells Fargo concluded that bank employees opened over 1.5 million deposit accounts that may not have been authorized. 
 
 The way it worked was that employees moved funds from customers' existing accounts into newly-created ones without their knowledge or consent, regulators say. The CFPB described this practice as "widespread." Customers were being charged for insufficient funds or overdraft fees -- because there wasn't enough money in their original accounts. 
 
 Additionally, Wells Fargo employees also submitted applications for 565,443 credit card accounts without their customers' knowledge or consent. Roughly 14,000 of those accounts incurred over $400,000 in fees, including annual fees, interest charges and overdraft-protection fees. 
 
 The CFPB said Wells Fargo will pay "full restitutions to all victims."

 Wells Fargo is being slapped with the largest penalty since the CFPB was founded in 2011. The bank agreed to pay $185 million in fines, along with $5 million to refund customers. 
 
 "We regret and take responsibility for any instances where customers may have received a product that they did not request," Wells Fargo said in a statement. 
 
 Wells Fargo has the highest market valuation among any bank in America, worth just north of $250 billion. Berkshire Hathaway (BRKA), the investment firm run legendary investor Warren Buffett, is the company's biggest shareholder. 
 
 Of the total fines, $100 million will go toward the CFPB's Civil Penalty Fund, $35 million will go to the Office of the Comptroller of the Currency, and another $50 million will be paid to the City and County of Los Angeles. 
 
 "One wonders whether (the CFPB) penalty of $100 million is enough," said David Vladeck, a Georgetown University law professor and former director of the Federal Trade Commission's Bureau of Consumer Protection. "It sounds like a big number, but for a bank the size of Wells Fargo, it isn't really." 
 
 Wells Fargo confirmed to CNNMoney that the 5,300 firings took place over several years. The bank listed 265,000 employees as of the end of 2015.

 "At Wells Fargo, when we make mistakes, we are open about it, we take responsibility, and we take action," the bank said in a memo to employees on Thursday. 
 
 The CFPB declined to comment on when the investigation began and what sparked it, citing agency policy. "We don't comment on how we uncover these matters," a spokesman said. 
 
 As part of the settlement, Wells Fargo needs to make changes to its sales practices and internal oversight. 
 
 Customers are fuming. Brian Kennedy, a Maryland retiree, told CNNMoney he detected an unauthorized Wells Fargo account had been created in his name about a year ago. He asked Wells Fargo about it and the bank closed it, he said. 
 
 "I didn't sign up for any bloody checking account," Kennedy, who is 57 years old, told CNNMoney. "They lost me as a banking customer and I have warned family and friends." 
 
 "Consumers must be able to trust their banks," said Mike Feuer, the Los Angeles City Attorney who joined the settlement. 
 
 Feuer's office sued Wells Fargo in May 2015 over allegations of unauthorized accounts. After filing the suit, his office received more than 1,000 calls and emails from customers as well as current and former Wells Fargo employees about the allegations. 
 
 Wells Fargo declined to say when it hired a consulting firm to investigate the allegations. However, a person familiar with the matter told CNNMoney the bank launched the review after the L.A. lawsuit was filed. 
 
 Even though the Wells Fargo scandal took place nationally, the settlement with L.A. requires the bank to specifically alert all its California customers to review their accounts and shut down ones they don't recognize or want. 
 
 "How does a bank that is supposed to have robust internal controls permit the creation of over a half-million dummy accounts?" asked Vladeck. "If I were a Wells Fargo customer, and fortunately I am not, I'd think seriously about finding a new bank."

– The city of Los Angeles is suing Wells Fargo, claiming the California-based bank pushed employees to engage "in unfair, unlawful, and fraudulent conduct" to hit sales quotas. The suit notes bank employees opened unauthorized accounts for customers, failed to close them when asked, and applied phony fees that hurt customers' credit. The bank says the issues stem from a few bad eggs, who have been disciplined or fired. But "on the rare occasions when Wells Fargo did take action against its employees for unethical sales conduct, Wells Fargo further victimized its customers by failing to inform them of the breaches, refund fees they were owed, or otherwise remedy the injuries that Wells Fargo and its bankers have caused," the suit alleges, per the Los Angeles Times. The suit also claims bank employees robbed customer accounts of money that was used to pay fees on accounts they never wanted, while the bank placed customers in collections and added "derogatory information" to credit reports, Courthouse News reports. The lawsuit follows a 2013 Times investigation which described Wells Fargo employees forging customers' signatures to open unwanted accounts. In new interviews, a former employee says false accounts were opened "daily," while a customer describes "a three-year battle" with the bank after his three accounts multiplied to 10. Per the suit: "Wells Fargo has generated a virtual fee-generating machine, through which its customers are harmed, its employees take the blame, and Wells Fargo reaps the profit." LA hopes to put an end to the practices, with up to a $2,500 fine for each violation, plus refunds for customers.
