## Title
Credit risk framework

## Abstract

A credit risk framework and systems and methods for using the same. The credit risk framework provides information regarding the eligibility of loans to be sold (delivered) to a purchaser, such as in the secondary mortgage market. The credit risk framework includes determining categories of potentially eligible loans. At least one risk segment is determined and an eligibility grid associated therewith. The eligibility grid is organized using two data elements as axes and forming boxes representing ranges of the two data elements. Each box is then further associated with additional information regarding any restrictions on loans that would fall in the box. Each risk segment may have its own level of delegated authority so as to tie risk to a delegation structure.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is a continuation of U.S. patent application Ser. No. 12/208,221, filed Sep. 10, 2008, which claims priority to U.S. Provisional Patent Application No. 60/971,838, filed Sep. 12, 2007, the contents of which are incorporated herein by reference in their entirety.


FIELD OF THE INVENTION
The present invention relates generally to the field of providing an indication of types of loans that a purchaser in the secondary mortgage market is willing to purchase.
BACKGROUND OF THE INVENTION
Potential homebuyers typically must borrow at least a portion of the cost of the home from lenders such as banks, credit unions, mortgage companies, savings and loan institutions, state and local housing finance agencies, and so on, to obtain the funds necessary to purchase or refinance their homes using the home as security for the loan. These lenders offer mortgage products to potential home buyers and, after the borrower applies for a loan, underwrite the borrower's loan application. The lenders who make (originate and fund) mortgage loans directly to home buyers comprise the “primary mortgage market.”
When a mortgage is made in the primary mortgage market, the lender can: (i) hold the loan as an investment in its portfolio, or (ii) sell the loan. The market for the sale and purchase of mortgages is referred to as “secondary mortgage market”. The secondary mortgage market includes sellers, typically lenders, and purchasers, e.g., pension funds, insurance companies, securities dealers, financial institutions and various other investors. Lenders often sell the loans they have issued, typically retaining a small percentage of the income stream from the loan, in order to procure a new supply of funds to make more home mortgage loans, thereby assuring home buyers a continual supply of mortgage credit.
However, most purchasers in the secondary mortgage market have requirements regarding the type of loan that they are willing to purchase. Current systems for communicating the types of loans a purchaser is willing to purchase are cumbersome and unclear. The plethora of loan types as well as the variability in borrowers and lenders themselves leads to a vast array of credit risks for each type of loan and a complex set of criteria for determining whether a loan is eligible for sale to a purchaser.
SUMMARY OF THE INVENTION
Generally speaking, the present invention relates to a credit risk framework and systems and methods for issuing and managing the same. According to one embodiment, a method of creating a credit risk framework including the steps of determining attributes that prevent a loan from being potentially eligible such that all loans are either potentially eligible or not; providing a visual representation of the potentially eligible loans; grouping the loans based upon at least two data elements, into a plurality of groups such that loans exhibiting like risk are grouped together; providing a visual representation of the grouping of loans as at least one eligibility grid; associating with each group of loans, a list of data element properties which exclude from eligibility loans having those data elements; and providing a visual representation of the list of data element properties as a sheet associated with the eligibility grid.
In another exemplary embodiment, a method for establishing the eligibility of a loan for purchase in the secondary mortgage market, includes the steps of determining if the loan is within a group of loans defined as potentially eligible based upon legal, business, and or financial restraints; selecting, based upon the seller of the loan, one of a plurality of eligibility grids that organize loans based on a risk metric; selecting a box within the selected grid, the box corresponding to certain data elements of the loan; and determining if additional information associated with the box indicates the loan is excluded from eligibility.
In another exemplary embodiment, a method of providing a visual representation of loans acceptable to a purchaser in the secondary mortgage market, including the steps of determining a group of loans ineligible to be purchased by the purchaser due to outside restrictions on the purchaser with the remainder of loans potentially eligible for purchase; determining credit risk segments within a group of potentially eligible loans; associating with each credit risk segment an eligibility grid, the eligibility grid having a first axis corresponding to a first data element and a second axis corresponding to a second data element, with each axis having gridlines extending therefrom, the intersection of first axis gridlines and second axis gridlines forming boxes representing potentially eligible loans having the same range of the first data element and the second data element; and associating with each box of the eligibility grid the presence or absence of additional information regarding eligibility based on one or more additional data elements.
In another exemplary embodiment, a computer implemented system for managing a mortgage obligation collateralized by a pool of mortgage backed-securities. The computer implemented system includes a central processing unit (CPU) and a storage device coupled to the CPU and having information stored therein for configuring the CPU to: determine a group of loans ineligible to be purchased by the purchaser due to outside restrictions on the purchaser with the remainder of loans potentially eligible for purchase; determine credit risk segments within a group of potentially eligible loans; associating with each credit risk segment an eligibility grid, the eligibility grid having a first axis correspond to a first data element and a second axis corresponding to a second data element, with each axis having gridlines extending therefrom, the intersection of first axis gridlines and second axis gridlines forming boxes representing potentially eligible loans having the same range of the first data element and the second data element; and associate with each box of the eligibility grid the presence or absence of additional information regarding eligibility based on one or more additional data elements.
In another exemplary embodiment, a credit risk framework. The credit framework comprises an eligibility grid, the eligibility grid has a first axis and a second axis, the first axis depicting borrower credit scores and the second axis depicting loan to value ratios. A plurality of first axis gridlines are provided extending from the first axis and corresponding to a credit score. A plurality of second axis gridlines are provided extending from the second axis and corresponding to a loan to value ratio. A plurality of boxes are defined by the intersection of first axis gridlines and second axis gridlines and representing discrete groupings of loans based the range of credit scores and range of loan to value ratios are defined by the respective gridlines forming each box, wherein some of the plurality of boxes are associated with exclusions that that indicate restrictions on loan eligibility.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Purchasers of mortgages in the secondary mortgage market typically have a particular range of risk that is acceptable in the loans they are willing to purchase. Purchasers make this determination based in part on data elements associated with the loan. Thus, certain loans are “eligible loans” and certain other loans will be “ineligible loans”. Eligible loans are those that the purchaser is willing to purchase. Ineligible loans are those that the purchaser is unwilling to purchase. In accordance with one embodiment, a purchaser in the secondary mortgage market utilizes a credit risk framework to communicate to potential sellers (typically lenders) the range of mortgage products that are ineligible and/or eligible. The credit framework segregates the universe of loans into those that are eligible for purchase by the purchaser and those that are not based on an empirical analysis of risk.
The credit risk framework utilizes a risk metric to assign a risk value to types of loans. In one embodiment, the risk metric is a measure of relative risk of each category of loans vis-à-vis the others rather than an exact measure of the absolute risk of that category of loan. The risk metric utilizes one or more data elements to determine risk. In this manner, the credit risk framework defines acceptable loans using a plurality of data elements associated with the loan. Data elements describe the attributes of a loan. These data elements may concern the loan, such as but not limited to loan dollar amount, the value of the loan compared to the value of the collateral, the type of interest rate structure, and the amount of the interest rate. In addition, the data elements may concern the borrower, including but not limited to borrower credit rating, borrow income levels, and borrower. Further, the data elements may concern the lender, such as but not limited to volume of mortgages sold in the secondary mortgage market, leverage, credit rating.
The credit risk framework may also reflect certain limitations that a purchaser may experience. Purchasers in the secondary mortgage market are often restricted by their own business model, by legal barriers, by capital requirements limitations and so on. The credit risk framework, in one embodiment, reflects these limitations on the purchaser, defining a universe of loans that are not eligible for purchase, either due to risk considerations or due to other limitations on the purchaser as discussed above.
In an exemplary embodiment, the risk metric is a credit risk model fee. The model fee metric utilizes data elements to assign a certain number of basis points (bps). In one embodiment, the model fee metric utilizes as data elements the loan to value (LTV) or combined loan to value ratio (CLTV), a credit score such as Fair Isaac & Co (FICO), product type, property type, occupancy type, loan purpose, document type, and mortgage insurance level. In an exemplary embodiment, the data elements utilized for the risk metric are the only data elements upon which eligibility is determined. At each tier of the credit risk framework, certain data elements are utilized to determine if the loan is eligible or not. All of the data elements used in the credit risk framework provide an aggregate risk indication for the loans they describe. Any other data elements not used in the credit risk framework (for risk determination), may be used to determine the pricing of the loans in the credit risk framework. Thus, any data elements used in the credit risk framework are used to determine if the purchaser is willing to buy the loan but not how much the purchaser will pay for the loan. Any remaining data elements not used in the credit risk framework may be used to affect the price the purchaser is willing to pay for a loan, but not whether the purchaser is willing to buy the loan.
The credit risk framework provides layers or tiers of restrictions regarding data elements in order to determine eligibility. Each tier removes some loans from potential eligibility and categorizes them as non-eligible loans with the remainder of potentially eligible loans grouped based on similarity of data elements. Each subsequent tier adds more data elements and more restrictions. The credit risk framework can consist of as many tiers as a purchaser feels are necessary to define the type of loans that are eligible for purchase.
In one exemplary embodiment shown in FIGS. 1-3, a credit risk framework 101 may be visualized as a two dimensional shape 102 whose perimeter 104 defines the boundary between eligible and ineligible loans. All of the potentially eligible loans lie within the shape 102, with the area 103 outside the perimeter 104 of the shape 102 representing the non-eligible loans. A segment 107 within the shape 102 represents the loans that are eligible by default for all sellers. In one embodiment, the segment 107 is visualized as substantially in the center of the shape 102. The subarea 111 between the segment 107 and the perimeter 104 of the shape 102 represents custom eligibility loans, i.e., loans that are not automatically eligible through the default eligibility segment, but which may be eligible if certain requirements are met.
In an exemplary embodiment, the category of loans defined as being potentially eligible for purchase may be further divided into risk segments. Risk segments represent a grouping of loans having similar data elements and risk. The credit risk framework can be used to tie risk for a particular segment of loans to a specific level of delegated authority. For example, credit and counterparty risk may be tied to a delegation structure. FIG. 2 illustrates an embodiment wherein a default eligibility segment 107 and two delegated authority segments 113, 114 are utilized. In FIG. 2 includes delegated authority segment A 113 and delegated authority segment B 114 are illustrated as substantially overlapping and as being disposed within the overall shape 102 representing the pool of potentially eligible loans in the credit risk framework.
The delegation structure represents one or more levels of authority, typically within the purchaser, that must approve a loan (or group of loans) for purchase. In one embodiment the delegation structure may represent a series of nested levels of authority, each level of delegated authority requiring a higher level of authority for approval. For embodiments utilizing the model risk fee metric, the bps value can be used to place the loans within a segment. For example, as seen in FIG. 2, a model fee threshold 116 can be provided to indicate which risk segment should be used. Thus, a different set of eligible loans than the default eligible loans can be designated, such as for a specific seller (such as one with extensive prior dealings with the purchaser) or a specific range of loan risk. In an exemplary embodiment, the application of the default eligibility structure or one of the delegated structures is based upon the lender, such that a certain lender may qualify for application of a delegated structure in determining which loans the purchaser can purchase. The delegated authority segments may represent a more relaxed risk outlook, wherein a broader range of loans are eligible with relatively fewer restrictions. In the alternative, delegated authority segments may represent a more conservative risk outlook, wherein a narrower range of loans are eligible for purchase and with relatively greater restrictions.
FIG. 3 illustrates a visualization an embodiment of the invention where eligible loans are subdivided into a delegated authority segment based on counterparty risk, measured by risk model fees in the embodiment of FIG. 3. For embodiments further parsing the eligible loans according to level of delegated authority, the levels of delegated authority, and their associated loans, are viewed as including at least a portion of the default eligibility segment 108 as well as at least a portion of the custom eligibility segment 111. In an exemplary embodiment, a plurality of levels of delegated authority are provided, each visualized as a delegated authority segment 112. In one embodiment, the visualization of the credit risk framework further includes an indication of the risk metric value for each set of eligible loans. As seen in FIG. 3, for embodiments utilizing a model fee, the threshold for qualification 116 for each of the segments 107, 113, 114 within the shape 102 is displayed within the respective segments 107, 113, 114.
In one embodiment the risk metric accounts for distinctions between flow transactions and bulk transactions, providing for a qualification threshold for each that may differ. In a further embodiment, the qualification threshold for bulk transactions may include a modifier to account for a predetermined tolerance determined based upon the relative risk of bulk transactions compared to flow transactions.
In an exemplary embodiment, the use of a delegated authority segment rather than the default eligibility segment is determined based on attributes of the lender. Such attributes may be included in a lender profile that indicates what attributes are necessary for a lender to qualify for the delegated authority. As shown in FIG. 5, the lender profile 510 includes counterparty assessment information 512, such as financial strength 513, regulatory structure 514, operational capabilities 515, and credit culture 516. The lender profile 510 also includes operational/processing capabilities 520, which typically alternative options for non-standard mortgage loans such as, but not limited to, reverse mortgages 521 and automated valuation model appraisals (AVM) 523.
Another method of visualizing the credit framework comprises utilizing an eligibility grid structure. In an exemplary embodiment, each risk segment is associated with an eligibility grid. Thus, a multitude of individual mortgage products may be associated with a single eligibility grid. Where more than one risk segment is present, such as a default eligibility segment and a delegated authority segment, each segment has an associated grid. The eligibility grid has at least two axes, with each axis being associated with a characteristic contributing to the calculation of risk. For example FIGS. 3-5 and 6A-6C depict an embodiment of a two-dimensional eligibility grid 301 having two axes 303, 304 perpendicular to each other, with the vertical or y-axis 303 being the credit score of the borrower (depicted in this case as the borrowers FICO score) and the horizontal axis or x-axis 304 being the loan to value ratio of the loan (or the CLTV ratio for loans whose collateral collateralizes more than one loan). As can be seen in FIGS. 3 to 5, horizontal grid lines 307 and vertical gridlines 308 extending from the axes define a box 310 on the grid. Each box 310 represents a group of loans having data elements within the range defined by the gridlines 307, 308 (i.e. by the corresponding value for each of the axes 303, 304 respectively), all of the loans meeting the defined attributes being eligible loans (either via default eligibility or delegated authority).
In one embodiment, not all loans defined by the attributes associated with each box are eligible loans. For example, in an exemplary embodiment, for each box 310, additional information is associated with each box 310 regarding the loans defined by the box 310. Such information may provide restrictions for eligibility of loans. The additional information may be inclusionary or exclusionary, i.e., the additional information may indicate data elements required for loans to be eligible loans or may indicate data elements of loans that will prevent them from being eligible loans.
By selecting the gradation and direction of the axes 303, 304, it is possible to organize the eligibility grid into restriction levels, i.e. areas of the eligibility grid having identical or similar levels of restriction (or inclusions) as evidence by the additional information. FIGS. 3 and 4 illustrate a eligibility grid for default eligibility having a “no restriction” area 311, a “restrictions” area 312, a “more restrictions” area 314, and a “even more restrictions” area 316, with each area having more restrictions than the preceding area and thus encompassing a smaller number of the loans than would otherwise be categorized within the box based solely on the data elements defined by the axes 303, 304. This additional information may be displayed on its own or as part of the box 310. The presence (or absence) of additional information may be indicated, such as visually, for the boxes of the grid.
In an exemplary embodiment, the additional information may constitute further limitations on the loans within the box that are required for the loan to be an eligible loan. In one embodiment, the additional information may constitute the existence of no additional limitations on the loans within the box in order for them to be eligible loans, i.e. all of the loans within the box are eligible loans, as shown in FIG. 3 with group 311.
FIGS. 4, 5, and 7A to 7L illustrate an embodiment wherein the additional information is displayed on a “jump sheet”. The jump sheets, in one embodiment, include information relating to the lender, information relating to the loan, and information relating to the borrower. As shown in FIG. 4, the jump sheet 701 may further include a reference identifier, such as a header 702, to identify at least some of the data elements associated with the loans encompassed by the jump sheet 701, for example the range of x-axis and y-axis value ranges associated with the box 510. The additional information is displayed on the jump sheet 701 as additional information text 703.
As previously mentioned, in one embodiment, the boxes 510 can be grouped based on associated risk. In a further embodiment, the jump sheet 701 includes group information 710. The group information 710 indicates with which group of boxes the jump sheet 701 is associated. FIG. 5 illustrates an embodiment where the boxes have been designated a group number and the associated jump page 701 includes that group number at 710. Additional indicators may be provided to identify the box 310 or boxes with which the jump sheet 701 is associated. For example, but without limitation, such additional indicators may include the use of a key-code system such as a colored box 310 or boxes that have identical or corresponding colors on their associated jump sheets 701.
Furthermore, boxes from different grids (and therefore different risk segments) can be associated with the same jump page. FIGS. 6A-6C illustrate eligibility grids for risk segments having model risk fees of 150, 250, and 300 bps respectively. As can be seen, the groupings 630-642 of the specific boxes 510 on each eligibility grids 301 changes as the model fee changes, but each utilizes the same jump pages 701 associated with each group 630-642. FIGS. 7A-7L illustrate the jump pages 701 that correspond to all three of the eligibility grids in FIGS. 6A-6C. It should be understood that any number of different eligibility grids 301 could utilize the same set of jump pages 701.
In an alternative embodiment shown in FIGS. 7A-7L, the additional information text 703 is further organized to include a matrix correlating the additional information to specific data elements. For example, FIGS. 7A-7L organize the additional information based upon document type 704 and property type 705, providing document and property specific additional information 706.
In an exemplary embodiment, the jump sheets 701 are presented as a separate document, such as a separate sheet of paper. In an exemplary embodiment, the credit risk framework is a component of an automated system such as a computer system. The computer system includes a graphical user interface, a processor, and memory. The credit risk framework, in one embodiment, is resident in the memory of the computer system and the graphical user interface is configured to display the credit risk framework when requested by a user. In one embodiment, the shape 102 is displayed on a graphical user interface, including all of the risk segments therein. Each risk segment may be associated with a corresponding eligibility grid, such that selecting or “mousing over” on the segment results in the corresponding eligibility grid being displayed.
For embodiments utilizing a graphical user interface, the jump sheets may be displayed in a number of ways to provide information to the user. In one exemplary embodiment, the jump sheets are associated with the eligibility grid such that selecting or “mousing over” a square in the eligibility grid results in a subwindow being displayed, preferably also on the graphical user interface.
In a further embodiment, the credit risk framework is implemented as a web based feature that is accessible over a network connection (e.g., over the World Wide Web). The functionality of the credit risk framework is implemented by one or more programs running on a web server or application server associated with such home and mortgage related product web site. An entity seeking to sell loans on the secondary mortgage market, such as a lender, accesses the credit risk framework web site through the World Wide Web or Internet network using a client machine. The client machine may be located at a user's home or office and is connectable to the Internet through an Internet Service Provider (ISP) or other available connection means. In one embodiment, the client machine may require authorization or be required to provide authentication before accessing the credit risk framework. As is well known, a client machine makes a request to a web server identified by a uniform resource locator (URL) and receives in return a web page formatted according to a Hyper Text Markup Language (“HTML”) or similar markup language, such as SGML or XML. In an alternative embodiment, the risk segments include hyperlinks to the corresponding eligibility grid and the boxes of the eligibility grid include hyperlinks to a web page that displays the corresponding jump sheet.
In a further embodiment, the lender profile 510 illustrated in FIG. 5 can be displayed as discussed above for the jump sheets to provide an indication of the lender profile for a currently displayed grid.
In a further embodiment, the information and restrictions expressed in the eligibility grid can be expressed as a business rule or a series of business rules. The business rules could, in an exemplary embodiment, be integrated with an underwriting or other loan procurement system of the purchaser to provide an indication as to the eligibility of the loan. Also, the business rules could be implemented as part of a loan originator system of the lender, such that the business rules are accessed during origination to ensure a loan is eligible before it closes.
