CFPB Dispels Myths Surrounding New Servicing Rules and QM Rule

first_img Data Provider Black Knight to Acquire Top of Mind 2 days ago Subscribe Servicers Navigate the Post-Pandemic World 2 days ago About Author: Brian Honea CFPB Credit Union National Association Mortgage Servicing Rules QM Rule Richard Cordray 2016-02-23 Brian Honea Data Provider Black Knight to Acquire Top of Mind 2 days ago The Consumer Financial Protection Bureau (CFPB)’s regulatory changes to the mortgage industry, namely the qualified mortgage (QM) rule and the new mortgage servicing rules adopted in January 2014, were met with a wave of criticism.Those criticisms were unfounded, according to CFPB Director Richard Cordray in an address given Tuesday at the Credit Union National Association (CUNA). The relationship between CUNA and the CFPB has been a rocky one, with CUNA claiming that credit unions should not fall under the CFPB’s oversight because they did not play a role in the 2008 financial crisis. Credit unions have complained that the CFPB’s oversight has resulted in higher compliance costs which in turn has resulted in fewer financial products available to their consumers.During his speech, Cordray defended the Bureau’s oversight of credit unions in addition to dispelling several myths surrounding the mortgage-related regulatory changes enacted by the CFPB since the Bureau’s inception four and a half years ago.In particular, he stated that the QM rule, or the “ability to repay” rule, was derided by many who called it the “quitting mortgage” rule and claimed that volume would plummet while mortgage costs would double. Critics of the QM rule claimed that no one would make any non-QM loans because of the risk of litigation, Cordray said. Still others claimed that smaller lenders would be unable to offer mortgage loans under the new regulatory environment.“We know change is hard and we understood the concerns, but at the Consumer Bureau, we never bought into the prophecies of doom and gloom,” Cordray said. “And as it turns out, we were right. The first set of mortgage rules have been in place for more than two years, and none of those pessimistic forecasts came to pass. In 2014, year one of our new rules, home purchase mortgages went up 4.6 percent, according to the authoritative HMDA (Home Mortgage Disclosure Act) data, and for jumbo loans, which are often non-QM loans, the increase was even higher. Even more relevant to this audience, the credit unions have thrived in this new and improved mortgage market. In fact, credit unions originated 39 percent more mortgage loans for home purchases in the first nine months of 2015 than the same period of 2014, according to the latest CUNA Mutual Group Report, which is prepared by CUNA’s own economists.”Richard CordrayCordray noted that the share of mortgage lending by credit unions is growing and that those institutions that have focused on compliance burdens have “overlooked the positive benefits of the rules.” Since the CFPB has build out a vigorous supervision program over non-bank lenders nad mortgage servicers, credit unions are being put on a level playing field for the first time, Cordray said.“Instead of attacking or resisting the CFPB, you should be supporting and speaking up for what it is doing for the best and most responsible financial institutions such as credit unions, that compete based on personal focus and strong customer service,” he said.Also, a “cottage industry” of lawyers and consultants expressed fear that widespread litigation against lenders would result from the passage of the QM rule, according to Cordray.“But now, more than two years later, so far as we can tell, not a single case has been brought against a mortgage lender for making a non-QM loan,” Cordray said.Click here to view Cordray’s entire speech. in Daily Dose, Featured, Government, News The Best Markets For Residential Property Investors 2 days ago Related Articles Share Save Brian Honea’s writing and editing career spans nearly two decades across many forms of media.

Sparsh Upadhyay7 May 2021 12:21 AMShare This – xUnderlining that the caretakers of Juvenile Centres, need to be vaccinated for their safety and also for the safety of the juveniles, the Gauhati High Court on Thursday (May 6) asked the Assam Government to consider treating them as “frontline warriors”. The Bench of Chief Justice Sudhanshu Dhulia and Justice Manash Ranjan Pathak observed, “The persons, who are taking care of juveniles in these Juvenile Centres, need to be vaccinated for their safety, but also for the safety of the juveniles. We, therefore, direct the State Government to consider treating these persons, who are taking care of Juvenile Care Centres as ‘frontline warriors’, and vaccinate them so that they do not pass on the disease to the children, who are under their care.”#GauhatiHighCourt: Persons, who are taking care of juveniles in the Juvenile Centres (in the state of #Assam), need to be vaccinated for their safety, and also for the safety of the juveniles.State Government asked to consider treating these persons, as “frontline warriors”. pic.twitter.com/Z6F0xBigf0— Live Law (@LiveLawIndia) May 7, 2021In related news, dealing with a petition filed by under-trial prisoners, currently locked in the Central Jail-6 Tihar, seeking certain directions for the provision of certain facilities in the jail, the Delhi High Court on Wednesday (May 5) issued a slew of directions. Considering that for inmates who are 45+ years of age, vaccines are already available and are with the Jail Superintendent, the Court directed that proper counseling be done for these inmates, and they be encouraged to take the vaccine, at the earliest. Recently, It was informed by the DG Prisoners (to the High Powered Committee of the Delhi High Court ) that the jail staff was declared “Front Line Workers” and thus was directed to be vaccinated in the First Phase of Vaccine Drive against COVID-19. “Members of the Committee have deliberated upon this issue and have resolved that all the jail inmates as well as jail staff are required to be vaccinated at the earliest so that the spread of COVID-19 inside the jail premises can be curtailed.” The Committee resolved. Further, dealing with a PIL filed regarding the state of prisoners amid the Covid-19 pandemic, the Uttarakhand High Court on Thursday (May 6) issued a slew of directions. The Bench directed the Jail Department and the Principal Secretary, Home / Prison, State of Uttarakhand, to ensure that the number of the prisoners being inoculated is drastically increased. The Government of Union Territory of Jammu and Kashmir recently informed the High Court that it was taking all relevant steps to ensure that all prisoners, whether convicted or under-trial, are inoculated against the Covid-19 virus. Also, the Orissa High Court recently passed significant directions to ensure that all inmates lodged in prisons of the State are vaccinated against the deadly Covid-19 virus. A Division Bench comprising of Chief Justice Dr. S. Muralidhar and Justice BP Routray was hearing two petitions concerning various issues persistent in the jails in Orissa. The Gauhati High Court also asked the Assam Government to file its response on a suo moto PIL concerning jail inmates, who are allegedly not being vaccinated in the state. Inter alia, the Division Bench at the Orissa High Court asked the State Government to work in coordination with the State Legal Services Authority and take time-bound steps for the remission of the sentences of prisoners found eligible for that benefit.

VA, NC and more digging out after snowstorm slams Southeast

first_imgABC News(NEW YORK) — The major winter storm that just pummeled the Southeast brought 2 feet of snow to Whitetop, Virginia, and up to 20 inches of powder in North Carolina. Richmond, Virginia, had its second-snowiest December day on record and double-digit totals were reported in South Carolina, Tennessee and as far west as Texas. Parts of West Virginia saw 20 inches of snow. Even Georgia got 8 inches. Now, the South is digging out. More than 276,000 people still were without power across seven states as of Monday morning — with over half of those in North Carolina. In Virginia, state police said they responded to over 1,000 car crashes on Sunday. The forecastThat storm now has moved to the coast, just off the Carolinas. Wet snow was falling Monday morning in the mountains of Tennessee, North Carolina, South Carolina, Virginia and Georgia. Snow and rain are expected to continue falling in the Southeast as the low pressure slowly begins to pull away from the coast. Not much snow accumulation is expected. Behind the massive storm, the Southeast will remain chilly into Tuesday, with early-morning wind chills in the 20s and 30s for many areas.Copyright © 2018, ABC Radio.

Doctors have wedding ceremony at hospital amid coronavirus pandemic

first_imgiStock(DURHAM, N.C.) — Two doctors working during the coronavirus pandemic marked what was supposed to be their wedding day with an impromptu ceremony at the hospital where they both work.Dr. Shelun Tsai, an OBGYN resident at Duke University Hospital, and Dr. Michael Sun, a resident in Duke Psychiatry’s program, planned to get married on Saturday, April 11, in North Carolina.With social distancing being encouraged during the novel coronavirus pandemic, one neighborhood has come up with a creative way to keep its annual Easter egg hunt alive. Brooke Peck a mom of one from Atlanta, Georgia, launched the Facebook event for the Spring egg hunt, encouraging other parents and their children to decorate and hang paper eggs in their windows.When the couple, who got engaged in 2016, had to postpone their official wedding, their colleagues at Duke University Hospital stepped in to make sure the couple’s would-be wedding day was still special.“They knew I’d postponed my wedding but people didn’t realize it was that day until I was there [at work] and I said it was supposed to be April 11,” Tsai told Good Morning America. “It started out small, that they wanted to make me a wedding dress, then it was a veil, then flowers and then it became everyone chipping in and jumping onboard.”“They literally started at 8 a.m. and in between patient care they’d get bits of stuff done and then had the ceremony at 3 p.m.,” she said of her colleagues. Before Tsai walked down the “aisle,” her colleagues set up a special room for her to change into her paper wedding gown and then arranged a “first look” moment between her and Sun.A nurse from the Labor and Delivery unit “officiated” the approximately 15-minute ceremony at Duke Birthing Center.The ceremony was watched on Zoom by nearly a dozen of Tsai’s and Sun’s friends, family and actual wedding party.At the end of the ceremony, Tsai and Sun rode off on a hospital transportation cart decorated with “Just Married” signs.The couple, who met in college, has moved their official wedding to October.“It was absolutely amazing,” Tsai said of her commemorative ceremony. “Every day I feel like we take care of our patients and we’re always so thoughtful and love what we do and to see that [my colleagues] also care so much about us and the things that mean so much to us, it was really touching.”“They’re really my work family and we really try to take care of each other,” she said.

Daunte Wright’s parents speak out after shooting in ABC News exclusive: ‘He’s never coming back’

first_imgABC News(NEW YORK) — The parents of Daunte Wright, a 20-year-old Black man who was shot and killed by a white police officer in a Minneapolis suburb on Sunday, said they “can’t accept” the notion that their son’s killing was “a mistake.”“I lost my son, he’s never coming back,” Daunte Wright’s father, Aubrey Wright, told ABC News’ Robin Roberts in an exclusive interview Tuesday on Good Morning America.“I can’t accept that — a mistake, that doesn’t even sound right,” he added. “This officer has been on the force for 26 years. I can’t accept that.”Daunte Wright was driving in Brooklyn Center, about 10 miles northwest of Minneapolis, when he was stopped by police on Sunday afternoon. The officers initially pulled him over for an expired registration tag on his car but determined during the traffic stop that he had an outstanding gross misdemeanor warrant, according to Brooklyn Center Police Chief Tim Gannon.As police attempted to take him into custody, Daunte Wright reentered the vehicle and one of the officers fired their weapon, striking him. The officer — identified by authorities as Kim Potter, a 26-year veteran of the Brooklyn Center Police Department — intended to deploy her Taser instead of her gun when she “accidentally” shot Daunte Wright, Gannon said.The car sped off, traveling several blocks before crashing into another vehicle. A female passenger in Daunte Wright’s car sustained non-life-threatening injuries during the crash and was transported to a nearby hospital. The passengers in the other vehicle were not injured, according to Gannon.Officers and medical personnel “attempted life-saving measures” on Daunte Wright but he died at the scene, Gannon said.Daunte Wright’s mother, Katie Wright, told ABC News that her son had called her during the traffic stop. She said he told her that police had pulled him over due to air fresheners hanging in his rear view mirror. She told him to take them down and to let her speak with police over the phone if they ask for his car insurance so she could give them the information. That’s when she heard police ask her son to step out of the vehicle.“Daunte said, ‘For what, am I in trouble?’ I heard the phone getting put down pretty hard,” Katie Wright said on GMA during Tuesday’s exclusive interview. “And then I heard scuffling and the girl that was with him screaming, and I heard an officer ask for them to hang up the phone and then I didn’t hear anything else.”“I tried to call back three, four times and the girl that was with him answered the phone and she said that they shot him and he was lying in the driver’s seat unresponsive,” the mother recalled, with tears streaming down her face. “And then I heard an officer ask her to hang up the phone again and then after that, that’s the last time I’ve seen my son. I haven’t seen him since.”She said she’s unsure why the situation escalated.“I know my son was scared. He’s afraid of the police, and I just seen and heard the fear in his voice,” she added. “But I don’t know why and it should have never escalated the way it did.”The mother described her son as “an amazing, loving kid” who “had a big heart,” “bright” smile and “loved basketball.”“He had a 2-year-old son that’s not going to be able to play basketball with him. He had sisters and brothers that he loved so much,” Katie Wright said. “He just had his whole life taken away from him. We had our hearts pulled out of our chests. He was my baby.”The parents said they want to see “justice served” and the officer who shot their son “held accountable for everything that she’s taken from us.” Brooklyn Center Mayor Mike Elliott has said he “fully support[s] releasing the officer of her duties.”“My position is that we cannot afford to make mistakes that lead to the loss of life of other people in our profession,” Elliott told reporters Monday.A preliminary report released Monday evening by the Hennepin County Medical Examiner said Daunte Wright died from a gunshot wound to the chest and that his death was a homicide.Earlier Monday at a press conference, the Brooklyn Center Police Department released body camera footage of the fatal encounter. The police chief said Potter can be heard in the video warning Daunte Wright and her fellow officers that she will be deploying her Taser.“However, the officer drew their handgun instead of their Taser,” Gannon told reporters. “It is my belief that the officer had the intention to deploy their Taser, but instead shot Mr. Wright with a single bullet. This appears to me, from what I viewed and the officer’s reaction and distress immediately after, that this was an accidental discharge that resulted in the tragic death of Mr. Wright.”Potter can be heard in the video yelling, “Holy s—, I just shot him!”The Minnesota Department of Public Safety’s Bureau of Criminal Apprehension is investigating the incident.A source with knowledge of the investigation told ABC News that Potter was field training another officer at the time of the deadly shooting.Civil rights attorney Benjamin Crump — who has represented the families of Trayvon Martin, Breonna Taylor, George Floyd and more — is one of the lawyers representing the Wright family and said that fatal encounters between police and people of color will only stop “when we start treating each other all the same.”“She was a training officer and so it’s not about training, it’s about implicit bias,” Crump said on GMA during Tuesday’s exclusive interview. “It’s about giving the same respect and consideration to people of color that we give to white American citizens. We don’t see these sort of things happening to white young people that we see happening over and over and over again to young, marginalized minorities.”“They could have given him a ticket, given him a notice to show up. But just like in George Floyd — they could have given him a ticket — they used the most force when it comes to dealing with marginalized minorities,” he added. “And we can’t have these two Americas — one where we treat Black Americans different from white Americans in policing.”Daunte Wright’s killing has sparked demonstrations — some violent — in Brooklyn Center, Minneapolis, Portland, New York and other U.S. cities. A curfew was imposed in Brooklyn Center, Minneapolis and other parts of Minnesota on Monday evening, and dozens of people were arrested amid riots overnight, according to Col. Matt Langer of the Minnesota State Patrol.Minnesota has mobilized its National Guard to Brooklyn Center at the request of local authorities. National Guard troops were already deployed in Minneapolis for the ongoing murder trial of Derek Chauvin, the former Minneapolis police officer charged in the May 2020 death of Floyd, which ignited protests nationwide and abroad.Daunte Wright’s family has called for peaceful protests.“I want to say thank you so much for the support and standing by us,” Katie Wright said, “and making sure that my son’s name doesn’t get swept under the rug.”President Joe Biden on Monday also called for “peace” and “calm.”“Peaceful protests, understandable, and the fact is that ,you know, we do know that the anger pain and trauma that exists in the Back community, and that environment is real, it’s serious, and it’s consequential,” Biden said. “But it doesn’t — will not justify violence and/or looting. And so, the question is, how we, in an orderly way, make clear that they get down to a full-blown investigation to determine what the facts are, and what is likely to have happened?”“The question is: was it an accident? Was it intentional? That remains to be determined by a full blown investigation,” Biden said.Former President Barack Obama and former first lady Michelle Obama said in a statement Tuesday, “The fact that this could happen even as the city of Minneapolis is going through the trial of Derek Chauvin and reliving the heart-wrenching murder of George Floyd indicates not just how important it is to conduct a full and transparent investigation, but also just how badly we need to reimagine policing and public safety in this country.”“We empathize with the pain that Black mothers, fathers, and children are feeling after yet another senseless tragedy,” the Obamas said. “And we will continue to work with all fair-minded Americans to confront historical inequities and bring about nationwide changes that are so long overdue.”Copyright © 2021, ABC Audio.

Wave breaking in dense plumes

first_imgSinking dense plumes are important in many oceanographic settings, notably the polar formation of deep and bottom waters. The dense water sources feeding such plumes are commonly affected by tidal modulation, leading to plume variability on short time scales. In a simple unsteady theory of one-dimensional plumes (based on conservation equations for volume, momentum, and buoyancy), this plume variability is manifested as waves that travel down the resulting current. Using numerical techniques applied to the hyperbolic conservation equations, this study investigates the novel concept that these waves may break as they travel down the plumes, triggering intense local mixing between the dense fluid and surrounding ocean. The results demonstrate that the waves break at geophysically relevant distances from the plume source. The location of wave breaking is very sensitive to plume drag from the seabed, the properties of the dense source, and the amplitude and period of the source modulation. To the extent that the simple model represents the real world, these results suggest that wave breaking originating from the tidal modulation of dense plumes could lead to a strong and previously unexplored source of local deep-ocean mixing.last_img read more
