This Amendment No. 10 amends and supplements the Schedule 13D, dated as of June 13, 1997, as amended, filed with respect to the common shares, par value $1.00 per share (the "Common Stock"), of PartnerRe Ltd., a Bermuda company (the "Company"). Item 3. Source and Amount of Funds or Other Consideration. Item 3 of the 13D is hereby amended and supplemented by adding the following paragraph before the final paragraph thereof: Capital Management's exercise of 677,873 warrants and 96,000 options was settled on May 2, 2003. Pursuant to such settlement, the Company issued 773,873 shares of Common Stock to SwissRe Capital Management (Bermuda) Ltd. ("Capital Management") and Capital Management paid the Company an aggregate exercise price of 271,238 shares of Common Stock. Following such settlement, Capital Management owns 8,340,731 shares of Common Stock. Item 4. Purpose of the Transaction. Item 4 of the 13D is hereby amended and supplemented by adding the following paragraphs at the end thereof: Capital Management's exercise of 677,873 warrants and 96,000 options was settled on May 2, 2003. Pursuant to such settlement, the Company issued 773,873 shares of Common Stock to Capital Management and Capital Management paid the Company an aggregate exercise price of 271,238 shares of Common Stock. Following such settlement, Capital Management owns 8,340,731 shares of Common Stock. Pursuant to Capital Management's request for registration, dated April 29, 2003, the Company filed a registration statement on Form S-3 with the Securities and Exchange Commission (the "SEC") on April 30, 2003 covering the resale by Capital Management of up to 8,340,731 shares of Common Stock. Such registration statement was declared effective on May 5, 2003. On May 6, 2003, Capital Management intends to enter into an agreement to sell to Citigroup Global Markets Inc. ("Citigroup") 8,340,731 shares of Common Stock pursuant to such registration statement, constituting all of the shares of Common Stock held by the reporting persons. Citigroup has informed Capital Management that Citigroup intends to reoffer such shares to investors. Given the positive outlook for the reinsurance market, SwissRe believes it can best capitalize on this opportunity by allocating its capacity directly to its reinsurance business. This transaction is also in line with SwissRe's strategy to reduce its equity exposure. Item 5. Interest in Securities of the Issuer. (a) The last sentence of Item 5(a) is hereby amended and restated in its entirety as follows: The reporting persons beneficially own 8,340,731 shares of Common Stock held by Capital Management or 15.6% of the outstanding Common Stock of the Company. (b) The last sentence of Item 5(b) is hereby amended and restated in its entirety as follows: The reporting persons have the shared power to vote and to dispose of 8,340,731 shares of Common Stock, or 15.6% of the outstanding Common Stock of the Company. (c) Item 5(c) is hereby amended and supplemented by adding the following language at the end thereof. Capital Management's exercise of 677,873 warrants and 96,000 options was settled on May 2, 2003. Pursuant to such settlement, the Company issued 773,873 shares of Common Stock to Capital Management and Capital Management paid the Company an aggregate exercise price of 271,238 shares of Common Stock. Following such settlement, Capital Management owns 8,340,731 shares of Common Stock. (d) - (e) Inapplicable.
