Global Reinsurer Capital

Aon Benfield estimates that global reinsurer capital totaled USD510 billion at June 30, 2013, an increase of 1% relative to December 31, 2012. This calculation is a broad measure of capital available for insurers to trade risk with and includes both traditional and non-traditional forms of reinsurer capital.

Major insurers and reinsurers generally maintained their solid operating performance in the first half of 2013, aided by tentative economic recovery in the US, continued growth in emerging markets and below average insured catastrophe losses. However, the support to capital positions was muted by the unwinding of unrealized investment gains that have accumulated on bond portfolios since the onset of the financial crisis. Interest rates began to climb in May and June ahead of expected tapering of the Federal Reserve’s quantitative easing program and yields have continued to rise into the second half. The impact on reported industry capital has been mitigated by the growing involvement of capital market investors in the reinsurance sector through non-equity participations, a trend presenting a growing challenge to ‘traditional’ reinsurer business models.

A NOTE OF CAUTION ON THE VAGARIES OF INSURANCE ACCOUNTING The first half of 2013 has highlighted the extent to which accounting choices can influence reported results. There have always been inconsistencies in the methodology applied to the calculation of combined ratios and returns on equity, two of the staple metrics for analyzing company performance. However, the real issue in this period was the accounting treatment of unrealized losses on bond portfolios relating to rising interest rates in May and June. Companies that classify a high proportion of their fixed-income securities as ‘held for trading’ saw a significant impact in the investment results reported through income statements, with consequent effects upon pre- and post-tax earnings and return on equity. In cases where the majority of bonds are held as ‘available for sale’, most of the impact was recorded below the line (in other comprehensive income) and taken directly to equity. As a consequence, direct comparison of company results can be misleading.

Executive Summary

Overview The first half of 2013 featured generally stable reinsurance demand and pricing, below average insured catastrophe losses, generally benign attritional loss experience and continued low interest rates. Bond yields rose in May and June ahead of expected tapering of the Federal Reserve’s quantitative easing program and, as a result, the unrealized gains that have accumulated on bond portfolios since the financial crisis have begun to unwind. This is negative for book values in the short-term, but positive for earnings in the longer-term.

New income streams and operating advantages are starting to flow to leading reinsurers that have engaged with the new capital flowing mainly from pension plans, life insurers, endowments and high net worth individuals. Their roles are mainly in (a) sponsoring transactions to lower their weighted average cost of underwriting capital, particularly for peak modeled perils (b) sharing quality underwriting performance and access to mature reinsurance and insurance relationships through sidecars and other managed vehicles and (c) managing bond funds where reinsurers have relationship and familiarity benefits with bond sponsors. These activities show the beginnings of a true rotation in how the reinsurance business will be capitalized.

Key Findings Aon Benfield estimates that global reinsurer capital rose by 1% to USD510 billion over the six months ending June 30, 2013, the generally solid earnings of major insurers and reinsurers and a continuing influx of new funds from capital markets investors being partially offset by unrealized losses on bond portfolios.

The shareholders’ funds of the 31 companies forming the Aon Benfield Aggregate (ABA) totaled USD313 billion, a reduction of 1% or USD4 billion since the end of 2012. The primary drivers were net income of USD16 billion offset by dividends and share buybacks totaling USD15 billion and unrealized investment losses of USD4 billion.

Gross property and casualty (P&C) premiums written by the ABA rose by 5% to USD109 billion, split 45% to direct insurance and 55% to reinsurance. The main engine of organic growth was the US market, driven by improving economic conditions and higher pricing in certain primary insurance lines.

Relative to the prior year, the ABA reported a 26% increase in P&C underwriting profit to USD8.9 billion, higher catastrophe losses being offset by more favorable prior year reserve development. The combined ratio improved by 1.7 points to 89.0%.

Annualized pre-tax operating returns (excluding all realized and unrealized gains and losses) relative to average total equity stood at 11.4%. Adjusting net income to include all unrealized movements reported through other comprehensive income, the return on average common equity stood at 7.8%.

Evolution of the ABA Aon Benfield Aggregate (ABA) reports are produced on a half-yearly basis and cover the reported results of 31 major reinsurers worldwide, with the aim of identifying trends in the non-life reinsurance marketplace. All of the constituents are publicly-listed, with the exception of two US subsidiaries of Berkshire Hathaway, namely General Reinsurance Corporation (Gen Re) and National Indemnity Company (NICO).

From 2013, Markel replaces Alterra as a constituent of the ABA, following its acquisition on May 1, 2013. Markel’s published results include Alterra’s contribution from that date only, but for the purposes of the ABA capital calculation (Exhibit 2), Alterra’s reported capital has been included in previous year-end totals.

ABA Capital

The reported shareholders’ funds of the 31 ABA companies totaled USD313 billion at June 30, 2013, a reduction of 1% since the end of 2012. Bond valuations were impacted by rising interest rates in May and June, denting reported earnings and resulting in significant unrealized losses taken directly to equity.

Capital Development Exhibit 3 shows the principal components of the change in ABA shareholders’ funds over the six months ending June 30, 2013. Improved underwriting performance relative to the prior year drove a 6% increase in reported net income, but this was out-weighed by the effects of more active capital management, adverse exchange rate movements and higher interest rates. NICO benefitted from USD6.1 billion of unrealized gains on its large equity holdings. The remainder of the ABA reported unrealized losses of USD10.0 billion, driven by the impact of rising yields on bond valuations. Excluding NICO, the reduction in ABA capital stood at 4%.

Exhibit 5 shows the movements in the reported shareholders’ funds of the ABA constituents over the six months ending June 30, 2013. Two-thirds of the companies reported reductions, driven by a combination of active capital management and unrealized losses on bond portfolios. Hiscox, Lancashire, and Validus all paid special dividends in the period. The effect of unrealized losses was most significant at Munich Re (USD2.8 billion), Swiss Re (USD2.7 billion), ACE (USD1.3 billion), XL (USD0.8 billion) and (USD0.5 billion). Markel reported a substantial increase in shareholders’ funds to USD6.3 billion, driven by the Alterra acquisition.

Capital Management Relative to the first half of 2012, dividends and share buybacks increased by 32% to USD14.9 billion, equivalent to 4.8% of opening shareholders’ funds. Dividend payments rose by 20% to USD10.9 billion, the most significant in capital terms being at Lancashire (16%), Hiscox (14%), Gen Re (10%), Beazley (9%) and Swiss Re (8%). Share buybacks rose by 81% to USD4.0 billion, the most active purchasers being Platinum (12%), PartnerRe (11%), Validus (9%), Axis (8%) and Montpelier Re (7%).

Premium Income

Gross property and casualty (P&C) premiums written by the ABA totaled USD109 billion in the first six months of 2013, an increase of 5% relative to the same period in the prior year. This was split 45% to direct insurance and 55% to reinsurance.

Exhibit 9 shows year-on-year movements in P&C gross premiums written across the ABA. Strong growth at Markel, Alleghany and Validus was partly acquisition-related: Alterra, Transatlantic and Flagstone were consolidated from May 1, 2013, March 6, 2012 and November 30, 2012, respectively. Excluding a large quota share contract in Florida, Everest Re reported growth of 12% (US insurance and reinsurance).

At the other end of the spectrum, Lancashire reported an 18% reduction in gross premiums written, driven by its exit from property direct and facultative and most retrocession business. The 15% reduction at NICO reflected the termination of a 20% quota share across most of Swiss Re’s P&C book (which represented 50% of net premiums earned in the first half of 2012), offset by non-specified growth elsewhere.

Exhibit 10 shows year-on-year movements in gross P&C reinsurance premiums written across the ABA, based on segmental disclosure. Six companies reported growth in excess of 15%, the top three results being influenced by the aforementioned acquisitions. Validus reported underlying growth of 21%, driven by new proportional crop treaties and property business written through the AlphaCat division. Allied World reported growth of 28%, driven by US property cat (through its partnership with Aeolus), crop and general casualty.

Net P&C insurance and reinsurance premiums written by the ABA rose by 7% to USD91.6 billion in the first half of 2013, an overall retention ratio of 84.2%, compared with 83.1% in the comparative period of the prior year. The result was skewed by the termination of the 20% quota share between Swiss Re and NICO at the end of 2012. More than half of the ABA companies actually reported increased reinsurance cession rates, contributory factors being increased use of third party capital and opportunistic purchases of additional catastrophe protection. It should be noted that Gen Re operates with an internal quota share to NICO.

Earnings

Operating performance remained solid in the first half of 2013, driven by higher premium leverage, below average insured natural catastrophe losses and increased prior year reserve releases. Bond valuations were reduced by rising interest rates in May and June, with only part of the impact reported through income statements.

Pre-tax profit reported through ABA income statements was unchanged at USD18.9 billion in the first half of 2013. P&C underwriting profit rose by 26% to USD8.9 billion, including an increased contribution of USD3.7 billion from prior year reserve releases. Ordinary investment income was stable and remained the main driver of the result. Capital gains more than halved to USD0.5 billion, but this outcome is misleading, as the majority of the unrealized losses on bond portfolios were taken directly to equity.

Exhibit 15 shows the distribution of reported pre-tax profits across the 31 ABA constituents. The impact of rising interest rates varied depending on investment classification choices and direct result comparison can therefore be misleading. The combined results of NICO, Swiss Re, Munich Re and ACE rose by 15% to USD10.5 billion, representing 56% of the total. Fairfax, one of the few companies taking all investment valuation changes through the income statement, reported an overall deficit, despite improved underwriting performance, driven by USD0.7 billion of unrealized losses.

Underwriting Performance The ABA combined ratio improved by 1.7 percentage points in the first half of 2013, reflecting higher premium leverage, lower attritional loss activity and increased prior year reserve releases. Worldwide insured natural catastrophe losses totaled USD20 billion, down 20% relative to both 2012 and the 10 year average (Source: Impact Forecasting). However, net catastrophe losses disclosed by the ABA rose by 55% to USD4.2 billion, reflecting higher cessions to the reinsurance market, particularly in the case of the floods in Central Europe.

The consequences of the low interest rate environment of recent years can clearly be seen in the declining yields on average cash and investments displayed in Exhibit 21.

ABA Business Model Evolution

A structural shift in the way capital is raised and deployed to mitigate insurance risk is in progress. The pool of potential investors is broadening and new money is flowing towards structures offering access to quality business at relatively low cost. These changes are forcing the ABA companies to re-evaluate their business models.

Who Are The New Investors? Reinsurance as an asset class has performed relatively well in an environment of low interest rates and is viewed as having limited correlation with broader capital market movements. These attributes have broadened the pool of potential investors to pension funds, high net worth individuals and sovereign wealth funds, who typically will:

 only enter the sector after extensive due diligence  invest a small percentage of the substantial assets at their disposal as a diversifying strategy  seek lower, more stable returns over longer timeframes than has historically been the case

How Is New Money Being Deployed? Much of the new capital is being channelled to specialist fund managers, who then deploy it into the insurance- linked securities (ILS) sector via products such as catastrophe bonds and industry loss warranties, or other ‘non- traditional’ structures, such as sidecars and collateralized reinsurance, on their investors’ behalf. The current focus is property catastrophe and retrocession business, particularly in the US market where exposures tend to be best understood, although diversification into other lines and territories is underway.

Implications for ‘Traditional’ Reinsurers Earnings were already under pressure from below average premium gearing and low interest rates. Now new vehicles operating at a lower cost of capital are making in-roads into higher-margin areas that remain a key driver of profits. These dynamics are forcing many ABA constituents to rethink their business models in the pursuit of differentiation and relevance in the market. In the catastrophe reinsurance space, this increasingly means being able to offer bigger line sizes, a full product suite including collateralized limits and enhanced claims service. Companies that are successful in attracting and deploying third party capital will potentially be able to advance their client offering, reduce earnings volatility through fee income, lower their own risk transfer costs and manage their capital base more effectively.

ABA Reaction Cost structures and client offerings are currently under review. Over time, it is expected that less reinsurance business will be written on rated balance sheets and more through ‘satellite’ structures backed by third party capital. RenaissanceRe has operated this model for many years and other ABA companies are now pursuing similar strategies. Capital market involvement that may previously have been limited to secondary investment in catastrophe bonds or simple quota share ‘sidecar’ structures is now morphing into full-on engagement.

Several ABA companies are already involved in the management of third party funds, including Amlin (Leadenhall), Montpelier Re (Blue Water), SCOR (Atropos) and Validus (AlphaCat). New capital markets divisions were established by Aspen, Axis, Lancashire, Montpelier Re, Sirius and XL in 2013, while Hannover Re (Leine) and RenaissanceRe (Medici) recently opened existing internal funds to third parties. An alternative route, pursued by Alleghany/Transatlantic (Pillar), Allied World (Aeolus) and Hiscox (Third Point Re), is to invest in strategic partnerships with established independent specialist fund managers.

19 The Aon Benfield Aggregate – Results for the six months ended June 30, 2013

Convergence in Action More than USD1 billion of capital has been injected into ABA sidecar vehicles in 2013, including eight new structures. Investors favor these reloadable joint ventures, as they have lower regulatory and operational entry barriers than new start-ups and a built-in exit strategy. These transactions included several Bermuda sponsors that have tapped the market multiple times, including Alterra (New Point V), Lancashire (Saltire I), Hiscox (Kiskadee Re), RenaissanceRe (Upsilon Re II) and Validus (AlphatCat Re). However, there were also new sponsors, such as ACE (Altair Re), Argo (Harambee Re), Everest Re (Mt. Logan Re) and PartnerRe (Lorenz Re).

Many ABA constituents have been able to take advantage of the newly available capacity from the capital markets to drive down their own risk transfer costs. Retrocession costs have reduced and several companies have purchased additional protection, with consequent impact on disclosed modeled exposures.
