METHOD AND SYSTEM FOR PROCESSING LOAN APPLICATIONS IN A
FINANCIAL INSTITUTION
FIELD OF THE INVENTION
The present invention relates, generally, to the field of loan processing systems, and in particular, to a unique method and system for processing loan applications in a financial institution.
BACKGROUND OF THE INVENTION
In financial institutions loan applications are processed by receiving information fi-om the loan applicant in the form of a form (electronic or paper). The loan applicant attaches details that include his personal information and his sources of income to the form while handing it over to the financial institution. The financial institution may receive this information directly fix)m the applicant either electronically or manually, or through an agent of the financial institution.
Traditionally, decisions to grant loans to loan applicants have been taken by loan officers of the financial institution. The loan officers analyze the form submitted by the loan applicant, manually determine the ability of the applicant to repay the loan and decide whether to grant the loan or not. This method, however, is perception based and a fixed rule is not used across the financial institution to grant loans. Perception leads to errors in judgments and may lead to numerous defeulted loan cases.
With the advent of technology, loan processing systems have been automated with the help of rule based engines. Business rules are set by administrators of the financial institution and configured based on ideal conditions required for the loan application to be granted. In most practical scenarios, the actual personal information does not allow the rule based engines to approve loan applications. Hence, manual intervention is required to approve loan applications with a little deviation fi-om the ideal conditions.

Complex rules based system can be built to cover many segments of applicants. However, configuring the rules engine for a new applicant segment is a tedious process involving manual intervention.
These and other problems in the existing systems in the art need to be addressed by a method and system that treats the loan processing systems in a bank, systematically. Hence, there is a need for a method and a system that establishes a relationship between past application data of the financial institution and the new applications received by the financial institution. Further, the method and system also needs to provide for fiinctionalities to easily refine the relationship between past application data and the new applications on a periodic basis without manual intervention.
SUMMARY OF THE INVENTION
In one embodiment of the present invention, a method for processing loan applications in a financial institution is provided. The method includes a step of receiving a first loan application fi"om a first loan applicant. The first loan apphcation includes personal information of the first loan applicant. Further, the method includes the step of determining a repayment score for the first loan applicant based on the personal information of the first loan applicant. The repayment score is calculated using a polynomial equation. The polynomial equation represents a relationship between personal information of a plurality of past loan applications and a plurality of past repayment scores. Furthermore, the method includes processing the first loan application based on a threshold set for repayment scores for a particular type of loan.
In another embodiment of the present invention, a system for processing loan applications in a financial institution is provided. The system comprises a user interface to receive a first loan application fi"om a first loan applicant. The first loan application includes personal information of the first loan applicant. The system further comprises a processor that is configured to determine a repayment score for the first loan applicant based on the personal information of the first loan applicant. The repayment score is

calculated using a polynomial equation that represents a relationship between a plurality of past loan ^plications and a plurality of past repayment scores. Furthermore, the processor is configured to process the first loan application based on a threshold set for repayment score for a particular type of loan.

DETAILED DESCRIPTION OF THE INVENTION
The following description is the fiill and informative description of the best method and system presently contemplated for carrying out the present invention which is known to the inventors at the time of filing the patent application. Of course, many modifications and adaptations will be apparent to those skilled in the relevant arts in view of the following description in view of the accompanying drawings and the appended claims. While the system and method described herein are provided with a certain degree of specificity, the present technique may be implemented with either greater or lesser specificity, depending on the needs of the user. Further, some of the features of the present technique may be used to get an advantage without the corresponding use of other

features described in the following paragraphs. As such, the present description should be considered as merely illustrative of the principles of the present technique and not in limitation thereof, since the present technique is defined solely by the claims.
Financial institutions such as banks and lending agencies are on a constant look out for people v^o are in need of money to fulfill their needs. To help people acquire assets or fulfill their needs, financial institutions offer loans of various types. Loans offered by various financial institutions include, but are not limited to, home loans, car loans, personal loans, educational loans, and medical loans. A process to process and grant loans to ^plicants is followed in every financial institution. FIG. 1 illustrates a conventional way of processing loan applications in financial institutions. A loan applicant 102 submits his loan application to the financial institution 104 through various means. Various means of submitting the loan application include filling a paper based form, submitting an online form, and contacting an agent. The loan application includes personal information of the loan applicant. Personal information of the loan applicant includes, but is not limited to, name, address, information about sources of income, and assets and liabilities of the applicant. The financial institution can process the loan application m multiple ways; it can either send the application to be processed by a rules engine 106 or the application can be sent to a loan officer 108 for decision making. In some cases, the rules engine 106 makes an initial decision based on personal information of the applicant and forwards the application to the loan officer 108 who then decides to grant or reject the loan. These methods however involve high level of human intervention and even the rules engine 106 needs to be re-configured to factor in new data that the financial institution receives every day.
FIG. 2 illustrates a method to process loan applications in a financial institution, according to one embodiment of the present invention. The method includes step 202 of receiving a first loan application for a first loan applicant. The first loan application includes personal information of the first loan applicant. Further, at step 204, a repayment score is determined for the first loan ^plicant based on the personal information of the first loan applicant. The repayment score is calculated using a polynomial equation that

represents a relationship between a plurality of past loan qjplications and a plurality of past repayment scores. At step 206, based on a threshold set for repayment scores for different types of loan, the first loan application is processed.
According to one embodiment of the present invention, the plurality of past repayment scores are decided based on a repayment history of each of the plurality of past loan applications. An administrator of the financial institution analyzes repayment trend of each loan application fi-om the plurality of past loan applications. Based on the duration in vs^ich the loan was closed or whether the loan was closed or no, the administrator assigns a repayment score to each of the plurality of past loan applications. The plurality of the past repayment scores are representative of a risk involved in granting loan to a particular profile of a loan qjplicant.
The plurality of past repayment scores are fiirther used in the polynomial equation, along with personal information in the plurality of past loan applications, to establish a relationship between personal infijrmation and repayment scores. According to one embodiment of the present invention, the polynomial equation that represents the relationship between personal information and repayment scores can be as follows:
y = ax:;'+bx^+cx^+dx"^'+... (1)
In Eq. (1) >- is repayment score for a loan application and xi to X4 represent personal information fi-om a loan application.
According to another embodiment of the present invention, the administrator of the financial institution selects a set of values for a set of coefficients (a, b, c, d...) and a degree (n) of the polynomial equation (1). According to another embodiment of the present invention, a random number generation module is used to select a set of values for the set of coefficients and the degree of Eq. (1). Further, personal information fi-om the plurality of past loan applications and the set of values are fed into Eq. (1) to calculate a plurality of automated repayment scores for each of the plurality of past loan applications. Furthermore, the plurality of automated repayment scores and the plurality
6

of past repayment scores, set by the administrator, are subtracted to calculate an error. If the error between the automated repayment scores and the past repayment scores is above a certain threshold, a new set of values for the set of coefficients and the degree of the polynomial equation is selected. The earlier process of calculating the error is then performed cyclically until the error between the plurality of automated repayment scores and the plurality of past repayment scores is below the threshold. The set of values that lead to error below the threshold is fed to the polynomial equation (1). Eq. (I) with the set of values and personal mformation fi-om the first loan application are used to calculate the repayment score for the first loan applicant. Based on the repayment score of the first loan applicant, the first loan application is processed.
FIG. 3 illustrates a system for processing loan applications in a financial institution, according to one embodiment of the present invention. The system includes a user interfiice 302, a processor 304, data repository 306, and an administrator user interfece 308. The user interfece 302 is configured to receive a first loan application fi-om a first loan applicant. The first loan application includes personal information of the loan applicant. The processor 304 is configured to determine a repayment score for the first loan ^plicant using personal information of the first loan applicant. The repayment score is calculated using a polynomial equation that represents a relationship between a plurality of past repayment scores and a plurality of past loan applications. Furthermore, the process 304 is configured to process tiie first loan application based on a threshold set for a particular type of loan.
According to one embodiment of the present invention, the data repository 306 stores personal information of the plurality of past loan applications. An administrator of the financial institution uses the administrator user interface 308 to set the plurality of past repayment scores for each of the plurality of past loan applications. The plurality of past repayment scores are set based on a duration taken to close the loan or whether the loan was closed or no. Further, the plurality of past repayment scores are stored in the data repository 306 corresponding to each of the plurality of loan applications. According to one embodiment of the present invention, the polynomial equation that represents the

relationship between personal information and repayment scores has been expressed as Eq. (1) in conjunction with description of FIG. 2.
In Eq. (1) >» is repayment score for a loan application and xi to X4 represent pereonal information fi-om a loan application. According to another embodiment of the present invention, the administrator of the financial institution uses the administrator user interfece 308 to select a set of values for a set of coefficients (a, b, c, d...) and a degree (n) of the polynomial equation (1). According to another embodiment of the present invention, a random number generation module is used to select a set of values for the set of coefficients and the degree of Eq. (1). Further, the processor 304 reads personal information of the plurality of past loan applications fi-om the data repository 306 and uses the set of values in Eq. (1) to calculate a plurality of automated repayment scores for each of the plurality of past loan applications.
Furthermore, the processor 304 calculates an error between the plurality of automated repayment scores and the plurality of past repayment scores. If the processor 304 communicates to the administrator via the administrator user interface 308 that the error between the automated repayment scores and the past repayment scores is above a certain threshold, a new set of values for the set of coefficients and the degree of the polynomial equation is selected using the administrator user interface 308. The processor 304 then calculates the error cyclically until the error between the plurality of automated repayment scores and the plurality of past repayment scores is below the threshold. The set of values that lead to error below the threshold is fed to the polynomial equation (1). Eq. (1) with the set of values and personal information fi-om the first loan application are used to calculate the repayment score for the first loan applicant. Based on the repayment score of the first loan appHcant, the first loan application is processed.
