Net vs gross premiums

Before delving further into the world of net premiums, let's revisit the distinction between net …

In this post, we will build a model for an insurance product with riders. The model will be built in Python using the cashflower package. An interesting part of this project will be that we will use two model point sets.

Data format

In this post, we will model an insurance product where a policyholder can have multiple coverages. For example, the policyholder can be insured against death and illness within the same policy.

In terms of model point data, the easiest approach would be to have additional columns in the …

Everyone - not only actuaries - becomes very interested in the mechanics of a real estate mortgage once they buy their first home.

A real estate mortgage is a loan from the bank to the customer that must be used to purchase real estate. The amount borrowed is typically quite large and the term is quite long (usually between 15 and 30 years). The payment frequency of real estate …

In this post, we will discuss the output of a cash flow model using the cashflower package in Python. In particular, we will check how to create individual and aggregated output, create an output only with a subset of columns and save a custom output.

Structure

The output of a cash flow model is a table where rows represent periods and columns represent variables. Data are the values of the variables for the given period.

The structure of the output depends on two …
