Segment information

ACE operates through five business segments: Insurance – North American P&C, Insurance – North American Agriculture, Insurance – Overseas General, Global Reinsurance, and Life. These segments distribute their products through various forms of brokers, agencies, and direct marketing programs. All business segments have established relationships with reinsurance intermediaries.

Effective January 1, 2013, the former Insurance – North American segment is presented in two distinct reportable segments:

Insurance – North American P&C and Insurance – North American Agriculture. Prior year amounts contained in this report have

been adjusted to conform to the new segment presentation.

The Insurance – North American P&C segment comprises our operations in the U.S., Canada, and Bermuda. This segment includes the operations of ACE USA (including ACE Canada), ACE Commercial Risk Services, ACE Private Risk Services, ACE Westchester, ACE Bermuda, and various run-off operations, including Brandywine. ACE USA is the North American retail operating division which provides a broad array of traditional and specialty P&C, A&H, and risk management products and services to a diverse group of North America commercial and non-commercial enterprises and consumers. ACE Commercial Risk Services addresses the insurance needs of small and mid-sized businesses in North America by delivering a broad array of specialty product solutions for targeted industries that lend themselves to technology-assisted underwriting. ACE Private Risk Services provides high-value personal lines coverages for high net worth individuals and families in North America. ACE Westchester focuses on the North American wholesale distribution of excess and surplus lines property, casualty, environmental, professional liability and inland marine products. ACE Bermuda provides commercial insurance products on an excess basis mainly to a global client base targeting Fortune 1000 companies and covering exposures that are generally low in frequency and high in severity. The run-off operations do not actively sell insurance products but are responsible for the management of certain existing policies and settlement of related claims.

The Insurance – North American Agriculture segment comprises our North American based businesses that provide a variety of coverages in the U.S. and Canada including crop insurance, primarily Multiple Peril Crop Insurance (MPCI) and crop-hail through Rain and Hail Insurance Services, Inc. as well as farm and ranch, and specialty P&C commercial insurance products and services through our ACE Agribusiness unit. The MPCI program is offered in conjunction with the U.S. Department of Agriculture.

The Insurance – Overseas General segment comprises ACE International and ACE Global Markets (AGM). ACE International comprises our retail commercial P&C, A&H, and personal lines businesses serving territories outside the U.S., Bermuda, and Canada, and the international supplemental A&H business of Combined Insurance. ACE International maintains a presence in every major insurance market in the world and is organized geographically along product lines that provide dedicated underwriting focus to customers. ACE International has four regions of operations: ACE Europe, ACE Asia Pacific, ACE Far East, and ACE Latin America. During 2013, ACE International expanded its operations with the acquisitions of ABA Seguros and Fianzas Monterrey in Mexico. Refer to Note 2 for additional information. Companies within the Insurance – Overseas General segment write a variety of insurance products including P&C, professional lines (directors and officers and errors and omissions), marine, energy, aviation, political risk, specialty consumer-oriented products, and A&H (principally accident and supplemental health). Combined Insurance distributes a wide range of supplemental A&H products. AGM, our London-based international specialty and excess and surplus lines business, includes Syndicate 2488, a wholly-owned ACE syndicate. AGM offers products through its parallel distribution network via ACE European Group Limited (AEGL) and Syndicate 2488. ACE provides funds at Lloyd's to support underwriting by Syndicate 2488, which is managed by ACE Underwriting Agencies Limited. AGM uses Syndicate 2488 to underwrite P&C business on a global basis through Lloyd's worldwide licenses. AGM uses AEGL to underwrite similar classes of business through its network of U.K. and European licenses, and in the U.S. where it is eligible to write excess and surplus lines business. The reinsurance operation of AGM is included in the Global Reinsurance segment.

The Global Reinsurance segment represents ACE's reinsurance operations comprising ACE Tempest Re Bermuda, ACE Tempest Re USA, ACE Tempest Re International, and ACE Tempest Re Canada. The Global Reinsurance segment also includes AGM's reinsurance operations. These divisions provide a broad range of traditional and specialty reinsurance products including property catastrophe, casualty, and property reinsurance coverages to a diverse array of primary P&C insurers.

The Life segment includes ACE's international life operations (ACE Life), ACE Tempest Life Re (ACE Life Re), and the North American supplemental A&H and life business of Combined Insurance. ACE Life provides a broad portfolio of protection and savings products including whole life, endowment plans, individual term life, group term life, group medical, personal accident, credit life, universal life and unit linked contracts through multiple distribution channels primarily in emerging markets including: Egypt, Hong Kong, Indonesia, South Korea, Taiwan, Thailand, and Vietnam; also throughout Latin America, selectively in Europe, and China through a non-consolidated joint venture insurance company. ACE Life Re helps clients (ceding companies) manage mortality, morbidity, and lapse risks embedded in their books of business. ACE Life Re's core business is a Bermuda-based operation which provides reinsurance to primary life insurers, focusing on guarantees included in certain fixed and variable annuity products and also on more traditional mortality reinsurance protection. ACE Life Re's U.S.-based traditional life reinsurance operation was discontinued for new business in January 2010. Since 2007, ACE Life Re has not quoted on new opportunities in the variable annuity reinsurance marketplace. Combined Insurance distributes specialty supplemental A&H and life insurance products targeted to middle income consumers and businesses in the U.S. and Canada.

Corporate includes ACE Limited, ACE Group Management and Holdings Ltd., ACE INA Holdings, Inc., and intercompany eliminations. Due to our initiatives to reduce reinsurance recoverable balances, losses recognized in connection with the commutation of ceded reinsurance contracts are generally not considered when assessing segment performance and, accordingly, are directly allocated to Corporate. Losses and loss expenses arise in connection with the commutation of ceded reinsurance contracts that result from a differential between the consideration received from reinsurers and the related reduction of reinsurance recoverable, principally related to the time value of money.

For segment reporting purposes, certain items have been presented in a different manner below than in the consolidated financial statements. Management uses underwriting income as the main measure of segment performance. ACE calculates underwriting income by subtracting Losses and loss expenses, Policy benefits, Policy acquisition costs, and Administrative expenses from Net premiums earned. For the Insurance – North American Agriculture segment, management includes gains and losses from fair value changes on crop derivatives as a component of underwriting income. For 2013, underwriting income in our Insurance – North American Agriculture segment was $89 million. This amount includes $1 million of realized losses related to crop derivatives which are included in Net realized gains (losses) below. For the Life segment, management includes Net investment income and (Gains) losses from fair value changes in separate account assets that do not qualify for separate account reporting under GAAP as components of Life underwriting income. For example, for 2013, Life underwriting income of $374 million includes Net investment income of $251 million and gains from fair value changes in separate account assets of $16 million.
