How a life insurance company insulated reduced churn through a predictive model

With the regulatory regime changing for insurance companies, the focus is on sufficient capital to cover risk. One of the key aspects of this new regime is to estimate the probability of Surrender, Lapsation and Claims.  With a well specified model, the insurance company was able to operate with the optimal capital based on the risk its portfolio carries. The same model can also be used by marketing to reduce Lapsation and Surrender by identifying vulnerable customers. It can also be used to target a less risky customer by using the insights from the Claims model.

A logistic regression model was used to score the customers based on a number of variables that include demographics of the policy holders, environmental variables such as interest rates and performance of the stock exchange as well as behaviour data in terms of purchase and payment modes. A high level of significance was set to ensure accuracy of the model as it was to be used by a regulator, and easily available data was used to keep the model practical and usable.

The results were that 90% of the lapsers were in the top three deciles of customers organised according to their probability of lapse (anything closer to 1). This was a robust model that identified the vulnerable consumers and the insurance company could target this group and retain them thus reducing churn.
