Statistics is baffling enough without being footloose with terminology.  So let’s clear up what we mean by a statistical sample.

The term “Statistical Sample” has a very specific meaning in the Cogent system.  It refers to a sample that is randomly selected from the entire population of loans eligible for a particular sample type (aka “audit shell”).  The suggested sample size is calculated every period by the system and is designed to yield a 95% confidence and 2% precision over 12 months.  This is the standard originally established by FNMA, FHLMC, and HUD for lenders who qualify to substitute ‘statistical sampling’ for the traditional 10% random sample.

The generic term ‘statistical sample’ is not very meaningful, in and of itself.  It simply refers to a sample in which some statistical principle has been employed, without defining which principle.  For example, it could refer merely to a randomly drawn sample, without specifying what population is being drawn from or how much precision will be achieved across what period.

To illustrate: most Cogent ProductionQC clients have at minimum a “Production” sample type, for which all loans originated in a particular period (typically a month) are eligible.  When a Statistical Sample (in the Cogent definition) is randomly drawn from this population, all loans have the same probability of being selected.  No distinction is made between loan type, loan source or any other loan characteristic.  It is intended  to establish a baseline of overall loan quality across the organization.

In order to achieve a 95% confidence and 2% precision for a particular category of loan, it is necessary to go beyond the “Statistical Sample”.  For example, in the Cogent system, to achieve this standard for all FHA loans originated, define a Targeted Query (Loan Type = FHA) and run the query.  The resulting screen displays all qualifying loans, including qualifying loans  that were randomly drawn previously in the “Statistical Sample” or any other samples in this period.  These count towards the total required.  Use the embedded Cogent Statistical Calculator to calculate the required (“suggested”) sample size for the period.  From the suggested sample size, subtract the number of qualifying loans that have previously been sampled and enter the result in the Sample Size box. The Cogent system will then randomly select the entered number of loans from the qualifying loans.

The Cogent “Stratified Sample” is in effect a pre-defined Targeted Sample.  Most typically, the Cogent system stratifies originations by Source or Channel and automatically tracks and calculates the sample size required for each stratum (Source or Channel), net of qualifying loans randomly drawn in the “Statistical Sample.”  Over 12 months, the Stratified Sample achieves 95% confidence and 2% precision for each stratum.  In Targeted Samples, this automated operation is performed by the user, using Cogent’s embedded tools.

Thus, in order to leverage the Cogent system’s sampling optimization, clients should begin sampling from the broadest category (all loans eligible) to the most narrow category (e.g., individual underwriters).  In this way, all loans selected in previous broad categories are counted towards ever narrower categories, minimizing the number of loans to be sampled and audited.

Berkery Noyes, “the only middle-market investment bank with research and M&A transaction teams dedicated to the mortgage technology, regulatory and compliance market,” has just published its 2009 Recap and 2010 Predictions For the Mortgage Technology Market.

Providing a view from 30,000 feet, the report lists a number of high-profile M&A transactions from 2009 and offers up a few trends in the mortgage technology space, including:

• accelerating vendor movement towards becoming a complete end-to-end solution provider
• more stringent lending guidelines and regulations increasing the need for compliance, fraud prevention and risk-mitigating technology solutions
• burden of ensuring proper compliance moves to the point of sale rather than merely at closing, and falls on all mortgage industry participants

In the context of these trends, the report states that market participants no longer see compliance and auditing solutions as “nice to have” – they have become “must have” solutions.

We couldn’t agree more.

 

 

One of the ways that servicers or investors can excise nonperforming assets from their portfolios is to try to put them back to originators by claiming fraud and/or breach of representations and warrants.   Potential malfeasance like this is uncovered via forensic audits, which have become increasingly popular since the mortgage crisis hit.  While forensic auditing for this purpose has typically been limited to institutions – investors, servicers, originators and mortgage insurers – the practice has now spread to the retail borrower, as described in today’s MortgageOrb article “When Forensic Loan Audits Are Used Against Lenders.”

This phenomenon has even touched Cogent.  Recently, we’ve been approached by a handful of clients to help them extract loan audit data from their Cogent systems for the purpose of forensic loan auditing.  Typically, this is in support of litigation in which opposing counsel requires every scrap of data that could be relevant.  Without a knowledge of both the mortgage quality control workflow and the application supporting it, this can be difficult for clients to accomplish on their own, especially after layoffs have reduced knowledgeable staff. 

Although projects like this are outside Cogent’s normal scope of work, we have the expertise to help clients.  More than anything, though, this is yet another reminder of why robust quality control is imperative in today’s world.

Here’s a timely and relevant learning experience: Sheshunoff, an established publisher of financial information, is offering a webinar on February 23rd called “Mortgage Servicing from A to Z: What Every Mortgage Servicer Needs to Know“.

The blurb reads as follows: “With the continuing scrutiny on the mortgage industry and the ever-changing regulatory landscape, it is more important than ever for mortgage servicers to stay on top of the latest regulatory developments and industry trends affecting this volatile area. Join our interactive audio conference, Mortgage Servicing from A to Z, as our expert speaker gives you an insiders view into federal and state regulatory requirements, hot topics and best practices.”

The ‘expert speaker’ in question is Dena M. Roudybush, senior counsel for Compliance Counsel, PC a Virginia based law firm that is dedicated to serving the mortgage banking and financial services industries.

Cogent, for one, has seen tremendous activity in the mortgage servicing arena, with particular interest in servicing quality control.  This session sounds like a good way to get up to speed on the major changes taking shape.

At the launch of HAMP (Housing Affordable Modification Program), the Treasury Department and the Department of Housing and Urban Development (HUD) set as their goal the modification of 3m to 4m mortgages.  Through December 2009, approximately 850,000 borrowers had been placed into trial modification programs and 66,000 had been placed into permanent modifications.  Hardly a blistering pace.

We outlined some of the issues with the structure and deployment of the program in our HAMP Best Practices article published in the December 2009 issue  of Servicing Management magazine.  Mentioned in that article were the documentation requirements of the program, which slowed the process down.  In recognition of this, Treasury and HUD have released new requirements for upfront documents and guidance on permanent modification conversion.

Effective for all trial period plans with effective dates on or after June 1, 2010, a servicer can only evaluate a borrower for HAMP after receiving an initial package that includes a request for modification and affidavit (RMA) form; the Internal Revenue Service (IRS) 4506T-EZ form, which gives servicers the ability to pull the borrower’s tax return; and two pay stubs from the borrower for proof of income.

Said Herb Allison, the assistant secretary for the Treasury: ““We’re making it as easy as possible for homeowners to provide the documents. A lot of the problem of converting the trial mods to permanent mods has been time delay between the verbal communication about their eligibility to actually getting the documents and sending them in.”

Every little bit helps.
