In Britain around 1900, established financial institutions for long-term savings such as life assurers, and pension funds which were just in their formative phase, did not make material allocations to publicly quoted equity markets or ordinary shares; long-established life assurers, for example, had less than 3 per cent allocated to the asset class (Baker and Collins 2003). Over the following 100 years, this picture radically changed, with equities emerging as the central asset class for many institutional investors and the term ‘the cult of (the) equity’ was coined (Scott 2002; Avrahampour 2015). As the century progressed, institutional investors superseded private individuals and became the dominant holders of British publicly quoted companies (Cheffins 2010). Despite the attractions of the asset class and their generally high returns, within a relatively short period by the end of the century, institutional equity exposure had peaked and was in decline both at life assurers and within pension funds. Here we highlight, and link together, the key actuarial (Turnbull 2017) and investing (Morecroft 2017) ideas that were influential in these developments. We also identify the main individuals who were instrumental in the application of equity investing to institutional portfolios. The article has an emphasis towards years from 1920 to 1960 when most of the changes to investment practice and actuarial theory occurred.

This paper takes a broad look at tax in general and some of the tax issues peculiar to life offices. A theoretical model for the taxation of life offices and their policyholders is then developed. Moving from theory to practice, the paper then offers its own solution to the ‘puzzle’. Appended by way of background reading are brief histories and summaries of life office tax in the UK, New Zealand, USA and Canada.

The paper first considers concepts of profit in economics, accountancy and the law relating to financial reporting. It then considers the nature of life assurance business and suggests the accounting standards appropriate to life assurance companies which would ordinarily result in accounts showing a ‘true and fair view’. An analysis of the E. C. Insurance Accounts Directive shows that there may be circumstances where its provisions conflict with such standards.

The paper considers each of the statutory solvency method, embedded value reporting and the accruals method, and the author finds all of them to be inconsistent with accounting standards and the requirements of the Directive.

The author puts forward the ‘Earned Profits’ method, which applies accountancy principles in determining assets and liabilities and takes credit for outstanding revenue matching acquisition costs. This approach is then used in analysing the value of a life assurance company and measuring the rate of return on capital.

The working party was required to establish what actuarial information is needed by the financial world for the proper evaluation of a bid for a quoted insurance company, and, in the light of these findings, to consider what may be required in the way of guidance to actuaries. The report considers the issuesw hich occur when life insurance companies aresu bject to takeovers and to other changes of ownership. The Takeover Code has many implications in such situations and these are discussed fully, particularly any conflicts of interest and the independence or otherwise of the actuaries involved. The interests of policyholders are considered and advice is proffered to actuaries. A Guidance Note is being issued.

In this paper an asset/liability model is used to compare the quality of information available from a set of stochastic simulations with a traditional deterministic sensitivity test approach.

The traditional approach applied to a range of variants of the basic model office fails to distinguish adequately very risky strategies from relatively secure strategies. The stochastic simulation method succeeds in ranking the various strategies considered into an intuitively satisfactory order of insolvency risk, as well as giving quantitative information on the relative probabilities of insolvency of different strategies and on the timing of potential solvency problems.

The theme of this paper is that life office valuation can be based on an analysis of the characteristics of the individual cash flows which form the net cash flow of an office. These cash flows may be compared with the income and gains derived from traded securities such as equities and gilts in order to assess their values. Standard asset pricing models of modern portfolio theory enable one to allow for lapse, mortality and other risks.

The methodology outlined in the paper is illustrated by reference to the very different types of revenue generated by non-profit, unit-linked and with-profits products. It is also used, in the valuation of future new business, to allow for the risks that expected sales volumes and profitability levels will not be achieved.

The paper provides a rationale for the choice of discount rates used in the valuation of a life office and facilitates the comparison of life office and alternative investment opportunities.
