         Following is a summary table of second quarter and six months
information (in millions, except per share amounts).

SECOND QUARTER SIX MONTHS 2001 2000 Change 2001 2000 Change ---- ---- ------ ---- ---- ------ Net income, as reported $ 1,627.0 $ 1,407.0 15.6% $ 3,158.8 $ 2,753.1 14.7% Income, as adjusted* $ 1,656.9 $ 1,430.7 15.8% $ 3,228.6 $ 2,794.8 15.5% PER SHARE RESULTS:** Net income, as reported $ 0.69 $ 0.60 15.0% $ 1.34 $ 1.17 14.5% Income, as adjusted* $ 0.70 $ 0.61 14.8% $ 1.37 $ 1.19 15.1% Average shares outstanding 2,357.6 2,339.3 2,358.2 2,342.7
* Adjusted to exclude the cumulative effect of a first quarter 2001 accounting change and realized capital gains (losses), net of taxes. ** Share information reflects the three-for-two split in the form of a 50 percent common stock dividend, paid July 28, 2000. Income before income taxes, minority interest and realized capital gains (losses) for the second quarter of 2001 amounted to $2.43 billion, an increase of 14.0 percent over the $2.13 billion reported in 2000. For the first six months of 2001, income before income taxes, minority interest, cumulative effect of a first quarter accounting change and realized capital gains (losses) increased 14.7 percent to $4.75 billion from $4.14 billion reported last year. Foreign exchange rates negatively affected the translation into U.S. dollars of foreign currency general insurance net premiums written and life insurance premium income and other considerations, as shown in the following table, which compares second quarter 2001 to second quarter 2000.
WORLDWIDE FOREIGN WORLDWIDE FOREIGN GENERAL GENERAL LIFE LIFE INSURANCE INSURANCE INSURANCE INSURANCE --------- --------- --------- --------- Premium Growth in Original Currency 15.8% 7.3%* 22.8%** 21.9%** Foreign Exchange Impact (3.5) (10.2) (9.2) (10.0) Premium Growth as Reported in U.S. $ 12.3% (2.9%) 13.6% 11.9%
* Excluding Risk Finance business, core Foreign General net premiums written rose 16.2% in original currency. ** Premium growth in original currency is reflected on a GAAP basis. Life insurance premium income and other considerations reflect an increase in original currency of 21.1% and 5.4%, respectively for Worldwide and Foreign Life. Premium income and other considerations are impacted by a decline in sales of tax-driven Guaranteed Income Bonds in the U.K. -more- 4 -3- Commenting on second quarter performance, AIG Chairman M.R. Greenberg said, "AIG had a good second quarter as a result of solid progress in most of our principal businesses and geographic markets. Excluding realized capital gains and losses, AIG's net income rose 15.8 percent to $1.66 billion. In the property-casualty market, pricing continued to improve. While the global economy remains soft, the flight to quality underway in many markets benefits AIG with our strong ratings and financial condition. We have undertaken a number of new marketing initiatives and alliances, and launched an array of new products that will benefit future growth in our business. "Reflecting rate increases in the commercial property-casualty market, worldwide general insurance net premiums written grew 12.3 percent (15.8 percent in original currency) to $5.06 billion. The combined ratio improved to 95.52 in the second quarter of 2001, compared to 95.92 a year ago. Net catastrophe losses, the majority from tropical storm Allison, were $30.0 million in the quarter, compared to $19.0 million in the second quarter of 2000. "In the United States, our Domestic Brokerage Group had record net premiums written of $2.82 billion and a combined ratio of 98.77. In last year's second quarter, net premiums written were $2.21 billion and the combined ratio was 99.27. While rates continue to firm, much more is needed for the industry to get back on an even keel and achieve overall profitability. In fact, over the past decade, rates declined for many classes of business by 50 to 75 percent. Over the same period, policy conditions broadened, which increased exposures in many areas, while loss cost trends have also increased significantly. AIG has declined to underwrite in excess of $4 billion of gross premiums over the past decade that would not have yielded a satisfactory underwriting profit, and we will continue to press strongly for rate adequacy. "HSB Group, Inc., which is providing valuable specialized capabilities to our worldwide general insurance operations, continued to produce good results in the second quarter of 2001. "Personal lines rates are rising, but are not yet adequate in a number of states. We maintain underwriting discipline, and in fact, recently announced that we intend to exit the New Jersey personal auto market, where necessary rate increases are virtually impossible to obtain. The rate application process takes years, and if a company decides to stop underwriting in the state, it can be held hostage for two or more years. The absence of meaningful reform ultimately increases costs for New Jersey drivers. This is hardly an example of a market economy. "United Guaranty Corporation, our mortgage guaranty insurance subsidiary, continues to achieve outstanding performance. Net premiums written increased 10.0 percent. -more- 5 -4- "Our Foreign General insurance operations had an excellent quarter and benefited from the global strengthening of property-casualty pricing. The combined ratio improved to 90.77 in the second quarter of 2001. Excluding Risk Finance business, which is highly transaction-oriented, the core business of our Foreign General operations increased by 16.2% in original currency. Both Japan and the United Kingdom, two of our major property-casualty markets, did particularly well. During the quarter, we announced plans to form an underwriting syndicate at Lloyd's, which will further enhance our global reach and product capabilities. "Transatlantic Holdings, Inc., whose results are reported through both AIG's Domestic and Foreign General insurance segments, grew in net premiums written and had a combined ratio of 102.9. Excluding $15 million in catastrophe losses, the combined ratio was 99.6. "Our Worldwide Life business had a very good quarter in both its domestic and foreign operations. This segment of our business met our targeted growth projections in most areas of the world. Overall, our Worldwide Life Division's operating income rose 19.7 percent, to $1.07 billion. Life insurance premiums and other considerations grew 14.8 percent or 21.1 percent on an original currency basis. Japan, one of our largest overseas markets, had an excellent quarter. Our life business in Japan now includes, in addition to ALICO, AIG Star Life Insurance Co., Ltd., the business we acquired as part of the Chiyoda reorganization. The addition of AIG Star Life increases the scope of our Japanese life operations and adds approximately 5,000 agents to our Japan life agency force. "A major development in the second quarter was the definitive agreement we announced in May to acquire American General Corporation. This acquisition will significantly strengthen our position in the domestic life insurance business and enhance our leadership in the rapidly growing retirement savings market, complementing SunAmerica's operations. The American General acquisition remains on track and American General has scheduled a shareholder vote for August 15. We have received approvals from a number of states, and expect the remaining approvals in August. We plan to close the transaction as soon as possible thereafter. Our third quarter results will include the costs and restructuring charges associated with the American General acquisition. AIG and American General already have extensive studies underway to identify and plan for revenue enhancement programs. We have project teams working on all aspects of the integration process, and are enthusiastic about the benefits we expect to realize from bringing American General into the AIG family. -more- 6 -5- "Our Financial Services Group had a very good quarter. Operating income increased 22.3 percent. International Lease Finance Corporation and AIG Financial Products Corp. both had excellent results. AIG's Consumer Finance Group continues to grow in the foreign markets in which it operates. American General's significant presence in domestic consumer finance will add materially to the overall scope of AIG's worldwide consumer finance business. AIG Trading Group Inc. strengthened its management team during the quarter, and operations are showing improved results. "The asset management business was obviously impacted by soft economic and financial market conditions during the second quarter. Nevertheless, our Asset Management Group experienced better results than the industry in sales of both variable annuities and mutual funds." GENERAL INSURANCE General insurance pretax income before realized capital losses for the second quarter of 2001 was $946.2 million, 6.6 percent above the $887.6 million last year. For the first six months of 2001, general insurance pretax income before realized capital gains (losses) was $1.92 billion, an increase of 8.9 percent, compared to $1.76 billion in 2000.
