Pursuant to an Agreement and Plan of Merger, dated as of October 9, 2020 (as amended by Amendment No. 1, dated November 2, 2020, the “Merger Agreement”), by and among Arch Capital Group Ltd., a Bermuda company limited by shares (“Arch”), the Issuer and Greysbridge Ltd., a Bermuda exempted company limited by shares and a wholly owned subsidiary of Arch, Arch agreed to acquire all of the common shares of the Issuer not already owned by Arch Re Bermuda at a cash purchase price of $35.00 per common share. In connection with the transactions contemplated by the Merger Agreement, the Issuer, Arch Re Bermuda and Gulf Re entered into a voting and support agreement, dated as of October 9, 2020, pursuant to which, among other things, each of Arch Re Bermuda and Gulf Re agreed to vote the common shares held by it in favor of the merger. On November 2, 2020, pursuant to an assignment and assumption agreement between Arch and Greysbridge Holdings Ltd., a Bermuda exempted company limited by shares and a wholly owned subsidiary of Arch (“Holdco”), Arch assigned its rights under the Merger Agreement to Holdco.

On February 16, 2021, (i) Arch Re Bermuda sold 230,400 common shares in the aggregate to the Kelso Funds pursuant to a purchase agreement among the Kelso Funds and Arch Re Bermuda (the “Kelso Purchase Agreement”), and (ii) Arch Re Bermuda sold 230,400 common shares to WP Windstar Investments Ltd. (“WP Windstar”) pursuant to a purchase agreement between WP Windstar and Arch Re Bermuda. The foregoing sales are referred to herein as the “Co-Investor Transfers.” The funds for the Kelso Funds’ purchase of the common shares pursuant to the Kelso Purchase Agreement were provided by Kelso & Company on behalf of its managed funds.

In connection with the Co-Investor Transfers, (i) the Kelso Funds entered into a voting and support agreement, dated as of February 16, 2021 (the “Kelso Voting and Support Agreement”), with the Issuer, pursuant to which, among other things, each of the Kelso Funds agreed to vote the common shares held by it in favor of the merger, and (ii) WP Windstar entered into a voting and support agreement, dated as of February 16, 2021, with the Issuer, pursuant to which, among other things, WP Windstar agreed to vote the common shares held by it in favor of the merger.

To enable Holdco to fund payment of the cash merger consideration, Holdco obtained equity commitments as follows: (i) pursuant to an equity commitment letter, dated as of February 16, 2021, among Holdco and the Kelso Funds (the “Kelso Equity Commitment Letter”), the Kelso Funds committed to make an aggregate cash contribution of up to $201,936,000 and to contribute to Holdco the 230,400 common shares of the Issuer owned by the Kelso Funds, (ii) pursuant to an equity commitment letter, dated as of February 16, 2021, among Holdco, certain funds managed by Warburg Pincus LLC (“Warburg Pincus”) and WP Windstar, such funds committed to make an aggregate cash contribution of up $201,936,000 and WP Windstar committed to contribute to Holdco the 230,400 common shares of the Issuer owned by WP Windstar, and (iii) pursuant to an equity commitment letter, dated as of February 16, 2021, between Holdco and Arch Re Bermuda, Arch Re Bermuda committed to make a cash contribution of up to $208,628,000 and to contribute to Holdco the 2,039,200 common shares of the Issuer owned by Arch Re Bermuda (collectively, the “Equity Financing”). The source of funds for the Kelso Funds’ cash commitment in respect of the Equity Financing is expected to be capital contributions from their respective limited partners. Upon consummation of the Equity Financing, Arch Re Bermuda will own 40% of Holdco, the Kelso Funds will own 30% of Holdco, and funds managed by Warburg Pincus will own 30% of Holdco. Upon consummation of the merger pursuant to the Merger Agreement, Holdco will be the sole shareholder of the Issuer.

In connection with the foregoing, (i) Holdco, Arch Re Bermuda, KIA and WP Windstar entered into an interim investors agreement, dated as of February 16, 2021 (the “Interim Investors Agreement”), pursuant to which such parties have agreed, in relevant part, to vote all shares of any voting securities of the Issuer owned by them in favor of the merger, not to transfer any equity interests of the Issuer that each party holds directly or indirectly without the other parties’ consent and to share certain expenses incurred in connection with the merger, and (ii) Arch, Kelso & Company and Warburg Pincus entered into a participant agreement, dated as of September 3, 2020 (the “Participant Agreement”), pursuant to which such parties have agreed to share certain expenses incurred in connection with the merger.

The foregoing descriptions of each of the Kelso Purchase Agreement, the Kelso Voting and Support Agreement, the Kelso Equity Commitment Letter, the Interim Investors Agreement and the Participant Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of such agreements, each of which is attached as an exhibit to this statement and is incorporated herein by reference.

Item 4.

Purpose of Transaction

The information set forth in Items 3 and 6 hereof are hereby incorporated by reference into this Item 4.

The purpose of the merger is to enable Holdco to acquire all of the common shares of the Issuer so that Holdco can operate the Issuer as a privately held company while retaining access to the Issuer’s underwriting platform and its licenses in Bermuda, the United States and Europe. The purpose of the Co-Investor Transfers is to enable the common shares transferred to be voted by the transferees in favor of the merger. In addition, in connection with the merger:

Dividend rate or policy, or indebtedness or capitalization. After the merger, the Issuer’s dividend policy with respect to its common shares will be determined by the board of the surviving company and the surviving company’s sole shareholder, which will be Holdco. Holders of the Issuer’s preference shares will be entitled to the same dividend and other relative rights, preferences, limitations and restrictions after the merger as are applied to the preference shares prior to the merger.

Board of directors; management. At the effective time of the merger, the director(s) of Greysbridge Ltd. immediately prior to the effective time will become the initial director(s) of the surviving company.

Delisting and deregistration of the Issuer’s equity securities. After the merger, the Reporting Persons expect that the Issuer’s common shares will be delisted from the Nasdaq Global Select Market, and the registration of the common shares under the Exchange Act will be terminated pursuant to Section 12(g)(4) of the Exchange Act. The Issuer’s preference shares will remain outstanding and, so long as the preference shares remain outstanding, the Issuer will remain obligated to file reports under the Exchange Act. If the Issuer’s outstanding preference shares are redeemed, the Reporting Persons expect that the Issuer’s preference shares thereafter would be delisted from the Nasdaq Global Select Market, and registration of the preference shares under the Exchange Act would be terminated pursuant to Section 12(g)(4) of the Exchange Act.

In addition to the foregoing, the Reporting Persons may communicate with current or prospective shareholders of the Issuer or other interested or relevant parties, concerning the business, operations, board composition, management, strategy and future plans of the Issuer and the matters set forth in this Item 4. The Reporting Persons have retained, and may in the future retain, advisors or consultants to assist them in evaluating their investment in the Issuer. The Reporting Persons may exchange information with any of the foregoing persons pursuant to confidentiality or similar agreements. The Reporting Persons may, at any time and from time to time, review and reconsider their position or change their purpose or take actions with respect to their investment in the Issuer as they deem appropriate, including formulating other plans, making other proposals or changing their intention with respect to the matters referred to in this Item 4. The Reporting Persons may also take steps to explore and prepare for various plans and actions, and hire advisors or consultants and consider potential proposals, before forming a plan or intention to engage in any such plan or action. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. The foregoing list of intentions, plans, strategies, negotiations, discussions, activities and potential transactions under consideration is subject to termination, evolution, modification or change at any time, without notice, and there can be no assurance that any of the Reporting Persons will take any of the actions set forth above.

Item 5.

Kelso LP and Kelso GP may be deemed to have beneficial ownership of the common shares held by KIA and KSN because (i) Kelso LP is the general partner of each of KIA and KSN and (ii) Kelso GP is the general partner of Kelso LP. Each of Kelso LP and Kelso GP disclaim beneficial ownership of all securities owned of record, or deemed beneficially owned by, KIA, KSN or KEP, and inclusion of these securities in this report shall not be deemed an admission of beneficial ownership of such securities for any purpose. In addition, due to their common control, KIA and KSN could be deemed to beneficially own each other’s securities. Each of KIA and KSN disclaim such beneficial ownership and inclusion of these securities in this report shall not be deemed an admission of beneficial ownership of all such securities for any purpose. To the best knowledge of the Reporting Persons, none of the individuals listed on Annex A attached hereto beneficially owns any common shares.

In addition, by virtue of the agreements discussed in Item 3 of this statement, the Reporting Persons, WP Windstar and Arch may be deemed to constitute a group for purposes of Rule 13d-3 under the Exchange Act. In the aggregate, such group would beneficially own 2,500,000 common shares, representing 12.57% of the outstanding common shares.

The following table sets forth the beneficial ownership of common shares of the Issuer as of the date hereof by persons that may, together with the Reporting Persons, be deemed to comprise a group for purposes of Rule 13d-3 under the Exchange Act. Each of the Reporting Persons disclaims beneficial ownership of all of the securities of the Issuer owned of record, or deemed beneficially owned by such persons, and inclusion of these securities in this statement shall not be deemed an admission of beneficial ownership of such securities for any purpose.
