Global Reinsurer Capital Aon Benfield estimates that global reinsurer capital totaled USD480 billion at June

30, 2012, an increase of 5% relative to December 31, 2011. This calculation is a

broad measure of capital available for reinsurance and includes both traditional and

non-traditional forms of reinsurer capital.

Exhibit 1: Global Reinsurer Capital

Source: Company reports, Aon Benfield Analytics

The relatively low level of insured catastrophe losses in the first half of 2012 allowed most mainstream insurance and reinsurance companies to report good earnings and consequent capital growth. Also noteworthy were the launch of two new rated Bermudian reinsurers (Third Point Re and PAC Re) and an increased level of investment in sidecars and catastrophe bonds. The new capital flowing into the sector is estimated at USD5 billion.

The Aon Benfield Aggregate – Results for the Six Months Ended June 30, 2012

Executive Summary Global reinsurer capital reached a record level of USD480 billion at June 30, 2012, an increase of 5% or USD25 billion since the end of 2011. New capital entering the sector is estimated at USD5 billion.

The reported capital of the 31 companies forming the ABA rose by 6% or USD15 billion to USD286 billion, driven primarily by USD14.5 billion of common net income and USD8.6 billion of unrealized capital gains. Dividends and share buybacks totaled USD9.1 billion.

Gross property and casualty insurance and reinsurance premiums written by the ABA rose by 6% to USD92.0 billion, principally driven by higher pricing in loss affected lines, with a number of companies deploying new sidecar capacity for catastrophe business. Net premiums written rose by 5% to USD76.3 billion.

The ABA combined ratio stood at 90.1%, down from 117.8% in the first half of 2011, producing an underwriting profit of USD6.6 billion, with all but one constituent reporting positive results.

The contribution to the combined ratio from natural catastrophe losses stood at 2.5 percentage points (USD1.6 billion), down from 31.8 percentage points (USD19.6 billion) in the first half of 2011.

The benefit to the combined ratio from prior year reserve releases stood at 3.2 percentage points (USD2.1 billion), down from 4.7 percentage points (USD2.9 billion) in the first half of 2011.

The total investment return reported by the ABA companies through their income statements fell by 4.9% to USD18.1 billion, equating to an annualized investment yield of 3.8%.

Direct exposure to sovereign debt issued by Greece, Ireland, Italy, Portugal and Spain remains low and is restricted to a handful of ABA companies.

Pre-tax profits reported by the ABA totaled USD17.8 billion, up from only USD1.4 billion in the first half of 2011, with all 31 constituents reporting positive results.

The ABA earned an annualized return on equity of 10.7% for the first half of 2012, calculated as common net income divided by average common equity.

Evolution of the ABA Going forward, the Aon Benfield Aggregate (ABA) report will be produced on a half-yearly basis, to allow the inclusion of certain companies that do not report quarterly. The aim is to provide a more representative view of the global property and casualty reinsurance marketplace. The new constituents are Amlin, Beazley, Catlin, Hiscox, Lancashire and QBE, while American Agricultural, Ariel and Maiden are no longer included. A full list of the 31 ABA companies can be found in Appendix 1. All are publicly-listed, with the exception of two US subsidiaries of Berkshire Hathaway, namely General Reinsurance Corporation (Gen Re) and National Indemnity Company (NICO). Prior year comparisons have been restated to reflect these changes.

Alleghany Corporation has replaced Transatlantic Holdings, Inc. as a constituent of the ABA, as a result of the acquisition that became effective on March 6, 2012. Alleghany’s published results only include the contribution of Transatlantic from that date. For the purposes of the ABA capital calculation, Transatlantic’s reported capital has been included in previous year-end totals.

Aon Benfield Aggregate Capital Reported capital is currently at a record level. The shareholders’ funds of the 31 ABA

companies totaled USD286 billion at June 30, 2012, an increase of 6% or USD15

billion since the end of 2011.

Exhibit 2: ABA Shareholders’ Funds

Source: Company reports, Aon Benfield Market Analysis

Capital Development The main drivers of the growth in capital were net income of USD14.7 billion and unrealized capital gains of USD8.6 billion (including a contribution of USD4.6 billion from NICO). Additional capital of USD2.7 billion included a contingent issuance of USD1.1 billion at Swiss Re and a USD635 million share placement at QBE. The principal offsetting factors were dividends of USD6.8 billion, share buybacks of USD2.3 billion and adverse foreign exchange movements of USD0.5 billion.

Alleghany’s shareholders’ funds more than doubled to USD6.3 billion in the period, as a result of the acquisition of Transatlantic. The only ABA constituent to report a reduction in shareholders’ funds was White Mountains - share buybacks totaling USD490 million in the wake of recent divestments out-weighed net income of USD120 million, resulting in a decline of 8%.

Premium Income The ABA wrote gross property and casualty (P&C) insurance and reinsurance

premiums totaling USD92.0 billion in the first half of 2012, an increase of 6.0%

relative to the prior year. Net premiums written rose by 5.3% to USD76.3 billion,

representing a retention rate of 82.9%.

Exhibit 6: ABA Gross Premiums Written


The main driver of premium growth in the first half of 2012 was increased pricing, particularly in loss-affected lines, with a number of companies deploying new sidecar capacity for catastrophe business. The sharp increase at Alleghany reflected a contribution of USD1.2 billion from newly-acquired Transatlantic. The premium reductions at Flagstone and Platinum were primarily driven by the desire to reduce catastrophe exposure.

Premium Distribution Net P&C insurance and reinsurance premiums written by the ABA totaled USD76.3 billion in the first half of 2012, an increase of 5% relative to the prior year. The top five represented almost 50% of the total and the top ten 69%. This study excludes P&C business written via Munich Re’s primary insurance operations (principally ERGO), to allow more consistent comparison with European peers.

Earnings The ABA reported pre-tax profit of USD17.8 billion for the first half of 2012, a

significant improvement on the near breakeven result seen in the prior year. The key

driver was the relative absence of natural catastrophe losses. The total investment

return fell by 5% to USD18.1 billion.

Exhibit 9: ABA Pre-Tax Result


All of the ABA companies reported pre-tax profits in the first half of 2012, a strong contrast to the comparative prior year period, when natural catastrophe losses drove over half of the constituents to pre-tax losses. Between them, NICO, Munich Re, Swiss Re and ACE represented 51% of the total.

Exhibit 10: Pre-Tax Profit/Loss (USD millions)


Underwriting Performance The ABA reported a P&C combined ratio of 90.1% for the first half of 2012, which equated to an underwriting profit of USD6.6 billion. Natural catastrophe losses totaled USD1.6 billion, down from USD19.6 billion in the prior year comparative period. Prior year reserve releases fell by 27% to USD2.1 billion.

Exhibit 11: ABA Combined Ratio Composition


All but one of the ABA companies reported P&C underwriting profits in the first half of 2012. Underwriters of material volumes of property catastrophe business were obvious beneficiaries of the relatively benign period for major losses. Expense ratios display significant variance, as shown in Exhibit 12.

A number of more short-tail focused ABA companies continue to derive significant benefit from positive prior year reserve development. White Mountains, QBE and Flagstone added to prior year reserves in the period.
