Ginnie Mae loans in forbearance decreased two basis points, from 7.34% to 7.32%; while the forbearance share for portfolio loans and private-label securities (PLS) decreased by 20 basis points, from 9.14% to 8.94%. The percentage of loans in forbearance for independent mortgage bank (IMB) servicers decreased 15 basis points to 5.54%, and the percentage of loans in forbearance for depository servicers increased two basis points to 5.28%.”The share of loans in forbearance has declined for three weeks in a row, with portfolio and PLS loans decreasing the most this week. This decline was due to a sharp increase in borrower exits, particularly for IMB servicers,” said Mike Fratantoni, MBA’s Senior Vice President and Chief Economist. “Requests for new forbearances dropped to six basis points, matching a survey low.”Of the cumulative forbearance exits for the period from June 1, 2020 through January 24, 2021, 27.9% represented borrowers who continued to make their monthly payments during their forbearance period; 25.8% resulted in a loan deferral/partial claim; 15.4% resulted in reinstatements; 13.8% represented borrowers who did not make all of their monthly payments and exited forbearance without a loss mitigation plan in place yet; 7.8% resulted in a loan modification or trial loan modification; and 7.5% resulted in loans paid off through either a refinance or by selling the home. The remaining 1.8% resulted in repayment plans, short sales, deed-in-lieus, or other reasons.“The housing market is quite strong, with home sales, home construction, and home price data all testifying to this strength,” said Fratantoni. “Policymakers and the mortgage industry have helped enable this during the pandemic by providing millions of homeowners support in the form of forbearance. The decision to extend the allowable duration of forbearance plans should provide for a smoother transition this year as the job market continues to recover.”The study also delved into weekly servicer call center volume, as a percentage of servicing portfolio volume calls increased from the previous week from 9.2% to 9.3%, while the average speed to answer decreased from 3.2 minutes to 2.3 minutes. The average call time to call centers decreased from 8.2 minutes to eight minutes.

Despite struggles, 2013 class will be fine

first_imgLet’s get this out of the way now: The recruiting season is going to turn out OK for USC. Come Wednesday, national signing day, the school is going to announce a recruiting class that will, naturally, be ranked near the top of essentially every national ranking possible. So exhale. It’ll be fine. It always is.In the wake of a disappointing 7-6 season, accentuated by a Sun Bowl loss to Georgia Tech on New Year’s Eve, you’ve read dozens of doom and gloom stories when it comes to the Trojans’ efforts on the recruiting trail. You’ve read about the de-commitments and, of course, there have been a handful of them: At least six once-USC commits reopened their recruiting process since November, seemingly the result of the disappointing 2012 campaign in which the program went from the Associated Press’ preseason No. 1 team to not receiving a single vote in the final AP poll. And so the speculation has continued: Will USC’s incoming recruiting class, once the consensus top class last July, fall apart?Well, no. Historically speaking, USC just doesn’t appear to do anything other than hailing in top-10 recruiting classes in football come winter time. It hasn’t had a class ranked lower than No. 8 nationally, per Yahoo! Sports’ Rivals.com, since February 2002.Moreover, isn’t it fair to give USC coach Lane Kiffin the benefit of the doubt here? For whatever shortcomings he has when it comes to leading a football program week in and week out as a head coach — and, to be clear, there are plenty — those aren’t what we’re dealing with here. Debating his recruiting prowess stands as a rather pointless exercise. The guy assembles football talent, can manage a roster and has quite the grasp on dealing with NCAA-imposed scholarship limitations. He might handle this just fine.Look at the class as currently constructed. As of Monday night, the Trojans’ class was ranked No. 7 by Rivals, with the highest average star rating (4.43) among any school. The next closest is Notre Dame with an average of 3.87. Not to mention, seven incoming freshmen, which include four five-star prospects in defensive tackle Kenny Bigelow of Elkton, Md., quarterback Max Browne of Sammamish, Wash., defensive back Su’a Cravens of Murrieta, Calif., and defensive back Leon McQuay III of Seffner, Fl., have enrolled for the spring semester and will participate in spring practices. Browne and Cravens were also the USA Today offensive and defensive national players of the year.“I can’t imagine a better collection of players to ever have joined a program mid-year,” Kiffin said in a statement last month. “It speaks volumes of the power of USC that four of the best players from the state of California and a trio of five-star out-of-state players chose to come here.”Yes, it does speak to USC’s “power,” or more specifically, to its ability to recruit. But this has never really been an honest question to ask. As much concern as there has been over a recruiting class some might proclaim to be falling apart, we’re arguing over semantics here. Is USC going to have the No. 1, the No. 5 or the No. 15-ranked recruiting class? Either way, in any scenario, the program’s going to be bringing in talent, even with scholarship reductions.USC, as a general rule, attracts talented football players, many from a Southern California region full of top-notch high school programs. And to Kiffin’s credit, he’s tapped into that during his tenure and convinced others from around the country to flock to South Los Angeles.This is what will happen Wednesday. This is what Kiffin does this time of year. He recruits — as well as any coach there is, really. But whether the Kiffin era, to put this in black and white terms, pans out for USC ultimately won’t stem from what happens in February. It won’t stem from whether a five-star defensive end flips, or commits, or de-commits or re-commits. Not that recruiting season is irrelevant by any means, but USC’s obstacles aren’t necessarily tied to it.It comes down to whether Kiffin can win not just in February but in November as well, to steal an old line once often used by Texas coach Mack Brown. It comes down to whether Kiffin, a collector of elite individual talent, can get USC to play elite, collectively. “The 19th Hole” runs Tuesdays.  To comment on this article email Joey at [email protected] or visit dailytrojan.com.last_img read more

Steelers’ Harrison mentoring LB Jones

first_imgJarvis Jones (AP Photo/File)PITTSBURGH (AP) – Pittsburgh Steelers outside linebacker Jarvis Jones is making the most of his wrist injury, getting mentored by 12-year veteran James Harrison.A five-time Pro Bowler and 2008 NFL defensive player of the year with 70 career sacks, Harrison signed to a one-year contract after Jones suffered a broken right wrist Sept. 21 at Carolina. Harrison retired Sept. 5, but the club needed someone to step in who knew the defense.“Right now, Jarvis is trying to be a student of the game, because he’s hurt, and he’s working hard to try to get back to being healthy,” Harrison said Friday. “But he’s always asking questions, why I’m doing something one way or another, and he’s taking notes to try to get as much information as possible.”Jones, the Steelers No. 1 pick last year, started eight of 14 games during an uneven rookie season. After an intense offseason program, Jones appeared ready this year to secure the right outside linebacker spot Harrison vacated when he signed a free-agent contract with Cincinnati in 2013. However, any progress Jones made was stunted when he was injured in Week 3.Jones had the cast removed Monday and has begun the rehabilitation process. There are still medical hurdles to clear, but Jones is on his way. He can begin practicing as early as the Steelers bye week, which begins after a Nov. 17 game at Tennessee, and then the club has three weeks to either activate him or put him on injured reserve for the rest of the season.“I’m mostly just doing some things to improve range of motion,” Jones said. “It was pretty stiff when I first got the cast off, but it’s slowly improving. I really can’t do anything to try to strengthen it, because I’m just four days out of my cast. Maybe I can do that next week, so I just hope to continue to get better.”If Jones can quickly get into shape and pick up near where he left off, the Steelers would be loaded at the linebacker position. Either Harrison or Arthur Moats, who has started the six games on the right side since Jones was injured, will have their playing time cut. While Moats has been solid, Harrison has made a bigger impact with four sacks in the past two games.Pittsburgh Steelers linebacker James Harrison (92) yells at an official from the sidelines during the first half of an NFL football game against the Tampa Bay Buccaneers on Sunday, Sept. 28, 2014 in Pittsburgh. (AP Photo/Gene J. Puskar)“I’ll be ready when my number is finally called, but as long as we’re winning it doesn’t matter who gets the most snaps,” Jones said. “If it’s me, I need to maintain the standard, getting sacks and making big plays.”Until then, he’ll continue to learn from Harrison and assistant coach Joey Porter, the Steelers starting right outside linebacker before Harrison.“Those guys played this game very hard, and they were very productive,” Jones said. “If I even come close to what they accomplished, I’ll have played a long time. So, I can’t wait to get back on the field and get started.”Notes: SS Troy Polamalu (knee) ILB Ryan Shazier (right knee), CB Ike Taylor (right forearm), S Shamarko Thomas (hamstring) and S Ross Ventrone (hamstring) are out this week. .

Titan Takes the Age Stage

first_imgSaturn’s giant moon has prompted a flurry of new science papers. Can anyone keep it billions of years old?Ever since the predicted global ocean on Titan was falsified, planetary scientists have been in theory-repair mode to keep it billions of years old. Cassini arrived in 2004 and started looking at a largely crater-free surface. The Huygens Probe landed on moist sand in January 2015, further puzzling scientists about the vast lakes of liquid that had been predicted. Now, after 12 years of encounters with the larger-than-Mercury moon of Saturn, Cassini has sent enough data for a comprehensive look at the geology, atmosphere and life span of Titan.There’s way too much verbiage to review in all these papers. What we will focus on are data and arguments that might keep this young-looking world as old as 4.5 billion years (its assumed age). First, take a look at the beautiful new global maps assembled by Cassini’s Virtual and Infrared Mapping Spectrometer (VIMS) posted by Space.com.  Titan still has “secrets”, the article says, calling it “a still-mysterious moon” after a decade of detailed study. There’s only one large crater visible, named Sinlap, “one of the youngest impact craters to dot Titan’s surface.” OK, so where are all the old ones?Cassini Spies Titan’s Tallest Peaks (Astrobiology Magazine). Enjoy the picture of Titan’s ski resort, rising almost 11,000 feet high. Smaller Pluto has bigger mountains than that.Discovering the bath scum on Titan (Helen Maynard-Casely on The Conversation). Features in one of the northern lakes seem to appear and disappear. Maynard-Casely helped identify one of the crystal forms of benzene and ethane in the “scum” on Titan’s lakeshores, but fails to mention the missing ethane that should have accumulated in deep deposits over billions of years. See also PhysOrg‘s writeup.Bubblin’ crude (New Scientist): A JPL scientist surmises that “if a methane-nitrogen mix rained down on a pure ethane lake, as much as 15 times the volume of nitrogen would be released, potentially making for some very big bubbles.” This might explain the “magic islands” disappearing act (see next article).  Quote:It just goes to show how much these alien worlds can surprise us, says Malaska. “We used to think of Titan as very Earth-like, but the more we learn about it, we learn it is really weird.”Titan’s “Magic Islands”: Transient features in a hydrocarbon sea (Icarus). Possible waves in the few northern lakes might explain the transient features. Can this dynamic environment have existed for billions of years?Nature, distribution, and origin of Titan’s Undifferentiated Plains (Icarus). Wind-driven materials forming “blandlands” at mid latitudes represent “an important repository of organic materials on Titan,” this paper says, claiming that depositional or sedimentary processes account for them. But why is the material not liquid, if predominantly ethane and methane?Fluvial erosion as a mechanism for crater modification on Titan (Icarus). Where are all the craters? They’ve been eroded away by liquid, this paper claims. Processes such as weathering, mass wasting, fluvial incision and deposition “may explain Titan’s crater distribution” (i.e., the surprisingly few that have been found). Wind can’t do it all, so rainfall and rivers must be accounting for the rest of the erosion.The fate of ethane in Titan’s hydrocarbon lakes and seas (Icarus). This paper seems tailor-made to answer the missing ethane problem. Where did it all go? A little hocus-pocus with unobservable processes might help, especially if we ignore the global-ocean deficiency and just focus on one lake, making assumptions that cannot be tested.Ethane is expected to be the dominant photochemical product on Titan’s surface and, in the absence of a process that sequesters it from exposed surface reservoirs, a major constituent of its lakes and seas. Absorption of Cassini’s 2.2 cm radar by Ligeia Mare however suggests that this north polar sea is dominated by methane. In order to explain this apparent ethane deficiency, we explore the possibility that Ligeia Mare is the visible part of an alkanofer [a layer that stores alkanes, a class of hydrocarbons] that interacted with an underlying clathrate layer and investigate the influence of this interaction on an assumed initial ethane–methane mixture in the liquid phase. We find that progressive liquid entrapment in clathrate allows the surface liquid reservoir to become methane-dominated for any initial ethane mole fraction below 0.75. If interactions between alkanofers and clathrates are common on Titan, this should lead to the emergence of many methane-dominated seas or lakes. Geomorphological map of the Afekan Crater region, Titan: Terrain relationships in the equatorial and mid-latitude regions (Icarus). These scientists make judgment calls on which terrains are the oldest: the undifferentiated plains, the mountains, the dunes, or the craters. They figure the dunes are the youngest, but their conclusions appear theory-dependent. “Our geomorphological mapping results are consistent with the equatorial and mid-latitudes of Titan being dominated by organic materials that have been deposited and emplaced by aeolian activity.”Material transport map of Titan: The fate of dunes (Icarus). In the massive dunefields, fluvial processes do not dominate, these planetary scientists say.  “Our results are consistent with aeolian transport being the dominant mechanism in the equatorial and mid-latitude zones.” They claim the dunes are in steady state, with material migrating poleward from the equator to an ultimate sink at 35 degrees latitude. But then what? “This observation suggests that either dune materials are converted or modified into plains units or that the margins of dunes are transport limited.” Remember, though, they have to account for 4.5 billion years of this process.Structure of Titan’s evaporites (Icarus). Liquid lands on the surface and evaporates. What’s left behind, and how much? They invent a model to explain the amount and distribution of evaporite deposits, needing to explain why there seems to be less in the south compared to the north. They estimate the maximum thickness of the deposits (not described in the Abstract). Why is it not liquid? Can the mass of solid deposits compensate for the expected global ocean?Alluvial Fan Morphology, distribution and formation on Titan (Icarus). The first survey of alluvial fans on Titan identified 82 of them, primarily at polar latitudes. These imply sediment transport downhill by rivers or wind, “suggesting that fluvial sediment transport may have been concentrated in the near-polar terrains in the geologically recent past.”Role of fluids in the tectonic evolution of Titan (Icarus). This paper tries to hide the missing liquid under the surface again. They link subsurface liquid to crustal deformations, claiming that subsurface liquid causes surface contraction, forming ridges. Once again, though, is this enough to sequester all the liquid that should have been found after billions of years? How does the liquid get under the sediments? This theory seems to raise more questions than answers.Update 4/05/16: Cryolava flow destabilization of crustal methane clathrate hydrate on Titan (Icarus). Another paper on Titan arrived since this entry was written. Famous planetary scientists Dennis Matson, Torrence Johnson and Christophe Sotin struggle to keep Titan’s methane concentrations going for long ages. They propose periodic cryovolcanic emissions, but admit: “However, this process cannot maintain methane resupply over geological time.” Conclusion: “The origin of Titan’s atmospheric methane and current resupply mechanism remain a mystery.”Tethys News. That’s all for Titan. Since our previous entry about Saturn’s other youthful moons (4/02/16), another Saturnian moon made the news: Tethys, third major moon out from the rings. Another paper in Icarus shares a surpising reversal in thinking: the big canyon, Ithaca Chasma—stretching nearly from pole to pole—was apparently not formed by the huge Odysseus impact on the opposite hemisphere. Although Tethys shares chemical/physical properties with Dione and Rhea (the next two big moons outward), the scientists “also identified spectral variations [on Tethys] that are unique in the Saturnian system.” Tethys is another “yold” world, bearing “geologically young surface features” made of large ice cubes and “geologically old weathered regions” made of small ice flakes. What? Tethys has weather? There’s no atmosphere to speak of. There is space weathering by the solar wind, but that should affect all surfaces equally. Unique features cause headaches for theorizers.It’s kind of fun watching the scientists pull their hair out to keep Titan old (what little hair is left after Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, comets, asteroids, etc.). We’re very happy that intelligent engineers got us out there for a close look, so we could witness the reactions. (Visited 34 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Canada Keeps Rolling Out Green Demo Homes

first_imgA national program launched three years ago invites homebuilders and developers to show off their greenest designsIn May 2006, the Canada Mortgage and Housing Corporation – the country’s national housing agency – announced an initiative designed to generate interest in eco-friendly housing among builders, developers, and the public.The CMHC, which calls the program the EQuilibrium Sustainable Housing Demonstration Initiative, solicited proposals for demonstration homes that, once built, would serve as models and inspiration for comparable home construction on a larger scale. Completed homes are open to the public for a minimum six-month demonstration period and are then monitored for performance for at least a year thereafter.The CMHC says 72 builder- and developer-led teams submitted proposals, and an independent committee of housing experts selected 12 teams to build demo homes. Six homes have been completed and winning project proposals for three more were announced in February.The completed homes include the Avalon Discovery House and the Laebon CHESS Project, both in Red Deer, Alberta; the Riverdale NetZero Project in Edmonton; the EcoTerra house in Eastman, Quebec; the Now House project, in Toronto; and the Minto Ecohome in Manotick, Ontario.last_img read more
