Income protection investigation

The CMI investigates the sickness experience of income protection policyholders

Brief history

A sub-committee of the CMI was set up in 1970 to investigate sickness rates under policies providing permanent health insurance, now better known as income protection. The main dataset extends back to 1975 although occupation class is only included from 1991. There are separate pools for individual business (still open) and group business (closed 2006).

Data and methodology

Data is submitted annually by life offices. Records were historically provided for each individual policy at the start and end of the year, and for each claim in payment during the year, but we now seek to capture movements in more detail and are flexible with formatting. See CMI data for more information about data submission.

Initially the investigations used a Manchester Unity approach, but now the experience is analysed in terms of claim inceptions and terminations (by recovery or death). The current methodology is described in CMI Working Paper 59.

Results

Subscribing life offices receive results in respect of the business for which they have submitted data. Aggregate 'All offices' results are also produced. CMI Working Paper 124 presents the most recent published analysis covering the period 2011 to 2016. Note: Data issues were subsequently discovered affecting the 2011-2016 claim inceptions experience. A summary of the impact is included in Working Paper 149.

The actual claim inceptions experience is compared with that expected using the IP06 graduated inception rates from investigation year 2011, and with that expected using the IPM 1991-98 graduations for 2011-2016 and earlier years. The actual claim terminations experience is compared with that expected using the IPM 1991-98 graduations.

An overview of the IPM 1991-98 graduations is presented in CMI Working Paper 48; details of the IP06 inceptions graduations can be found in CMI Working Paper 120

Claim experience tables

“IP11” claim inception and termination rates, based on individual IP experience of males and females, separately by occupation class, in 2007-2016, were finalised in September 2020. Note: Data issues were subsequently discovered affecting the claim inception rates. A spreadsheet of indicative adjustments to the rates is available alongside Working Paper 136.

Analysis of actual experience compared to that expected using the IP11 rates will commence from investigation year 2017.

The CMI has previously published three main sets of graduated rates for individual IP claim inceptions and two for terminations. The “IP06” claim inception rates were based on individual IP experience of males and females, separately by occupation class, in 2003-2010, and were published in March 2019 alongside Working Paper 120. IPM 1991-98, reflects the experience of male lives in CMI occupation class 1 policies for 1991-98, with an overview presented in CMI Working Paper 48.

The CMI Income Protection Rate Table Tool is a spreadsheet-based application, designed to assist practitioners in deriving claim inception and termination rates, as well as other factors required for their in-house profit testing, valuation and experience analysis tools, such as claim annuity values. It is intended to help practitioners make full use of the published graduations and experience. Version 1.2 of the CMI IP Tool incorporates the “IP11” claim inception and termination rates.

Further analysis

An analysis of individual Income Protection experience, 1991-2009, by cause of sickness is contained in CMI Working Paper 72.  An accompanying spreadsheet containing two databases, covering inceptions and terminations experience, was also made available to enable practitioners to pursue further investigations. An updated version of these databases, covering 1991-2010, was released alongside Working Paper 96 in which some of the previous analyses were updated.

Supplementary analyses to those included in regular ‘all offices’ results were released in Working Paper 102. These consider IP experience in 2003-2010 by benefit amount and policy duration.

    The world is changing. The fourth industrial revolution, globalisation and the COVID-19 pandemic are up-ending traditional social and business norms around the world; changes that were once predictable and steady are now faster and more profound. In response to this tumultuous transformation, Tan Suee Chieh has advocated a reinvention of the actuarial profession, through the adoption of the IFoA’s Vision, Skills, Mindsets and Domains (VSMD) Strategy, to ensure actuaries remain relevant and forward-looking.

    Tools like python/R are being heavily used to provide end-to-end analytical solutions for risk management. They help to set up a framework/platform to collect risk data and work out stochastic analytics to provide insights into the risks faced by a firm, be it in any sector. Data science techniques are being used to not only assess risk, but to predict outcomes in the future based on stochastic analysis and impacts of mitigation techniques. This webinar talks about the possible applications of technology to assist actuarial advice in such situations.

    The paper “Asset liability modelling in the quantum era” shall be presented by its authors, Tim Berry and James Sharpe, and chaired by Andrew Smith, Assistant Professor in the School of Mathematics and Statistics at University College Dublin. This gives a summary of historical and current practices in ALM, and then gives an insight into what ALM may be like in the immediate future by demonstrating how quantum computers can be used for ALM. A quantum algorithm for optimising ALM calculations is presented and tested using a quantum computer.

    Internal audit is often the Cinderella of the audit world. It’s a regulatory requirement for insurance companies to have an internal audit function, so why not make it as useful as possible?  This session will look at how to link an internal audit plan to the risk register, and how that helps audit committees and boards to spot problems and fix them. And, of course, how to demonstrate that this is happening.
