Overview of Data Preparation

Data preparation involves collection of the required data, and deciding sources and systems to extract data. It also involves cleansing the data by removing financial statements that do not satisfy the following criteria:

» Ratio checks: running the dataset through a series of data cleansing rules

» Default definition: consistent definition of default has to be determined to properly classify the obligors of the underlying data into defaulters and non-defaulters

» Determine the default horizon: determining a time window to classify the financial statements into defaults and non-defaults

Above criteria ensure that the data contains information of all obligors and the information is consistent with the business segment for which the model is being built .

Probability of Default Modeling 7

Defining DefaultMethodology for tagging financial statements as default

» If financial statements were less than 3 month before default event then these statements were removed from the model development

» If 2 statements were available from 4 to 21 months before default event then statement closer to default event was kept and tagged as default and other statement was dropped

» If a defaulted obligor had a statement that was more than 21 months before default event then the statement was tagged as non-default

> 21 months

Tag as non-default Remove statement Tag as default Remove statement

4 - 21 months <= 3 months Default Event

Basic ChecksAll statements were passed through a series of filtering criteria

» Total Assets <=0

» Total Liabilities < =0

» Total Revenue <=0

» Total assets do not match to the sum of total liabilities and total equity reserves (a threshold of 2% was used)

» Cash and Equivalents < 0

1. Refer appendix 11 for details of basic check analysis

FINAL DATA SAMPLE (Before Basic Checks)

Total Statements: 868

Unique MFIs: 293

Defaults: 16 (1.84%)

34 (3.9%) statements dropped

FINAL SAMPLE FOR MODEL DEVELOPMENT

Total Statements: 834

Unique MFIs: 292

Defaults: 16 (1.92%)

» Total Current Assets < 0

» Total Non Current Assets < 0

» Depreciation and Amortization < 0

» Total Operating Expenses < 0

» Total Long Term Liabilities < 0

In general, factors are evaluated on the following set of criteria

» Position Analysis: There must be enough observations. Observations where many values are missing typically indicate that the information is difficult to obtain. This information should therefore not be included in the final model

» Factors must be intuitive. Experienced credit analysts should be familiar with the factor and its relationship with credit risk given the credit culture in which they operate

» Factors must be consistent with expectations. Factor behaviour should be consistent with business judgment and any deviations in expectations should be easily explained

» Factors must be powerful. The ultimate list of factors incorporated into the model should exhibit a high degree of discriminatory power on the basis of credit risk

» As number of defaults are very low i.e. 16, we kept all the factors with positive accuracy ratio for MFA

» Return ratios e.g. ROA and ROE are not present in the candidate factors list because MFIs typically operate on low return and higher base i.e. large assets

Logistic Regression Models

1. For estimated coefficients and p value refer appendix 1

2. AR = Accuracy Ratio

Model Number of Factors Significance Level1 AR2 Comments

Model 1 5 P Value <= 0.05 69.5%  

Model 2 8 P Value <= 0.1 77.8%  

Model 3 6 P Value <= 0.1 73.4% Best model after dropping Pct_Urban_Clients_Volume

Model 4 4 P Value <= 0.05 65.5% Best model after dropping Avg_outstanding_loansize

Model 5 5 P Value <= 0.1 69.4% Best model after dropping Avg_outstanding_loansize

» Due to low number of defaults we also considered models with 90% significance level of estimated coefficients

» Pct_Urban_Clients_Volume represents percentage of urban and semi-urban borrowers of an MFI’s portfolio. Though this factors comes significant at 90% significance but we recommend not to include this factor in the model because MFIs typically have semi-urban and rural borrowers. Model should not penalize an MFI for having large base of rural clients

» Avg_outstanding_loansize was used as a proxy for income level of borrowers of MFIs. But given low accuracy ratio of this factor we also considered models after dropping this factor which resulted in a drop of 6% in AR for model 4 and 11% for model 5 compared to model 1 and model 2 respectively
