UNAUDITED PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS

On March 22, 2019, RenaissanceRe Specialty Holdings (UK) Limited, a wholly owned subsidiary of RenaissanceRe Holdings Ltd. (“RenaissanceRe”), completed its previously announced purchase of all of the share capital of Tokio Millennium Re AG (now known as RenaissanceRe Europe AG) (“RenaissanceRe Europe”), Tokio Millennium Re (UK) Limited (now known as RenaissanceRe (UK) Limited) (“RenaissanceRe UK”), and their respective subsidiaries (collectively, the “TMR Group Entities”) pursuant to a Stock Purchase Agreement by and among the Company, Tokio Marine & Nichido Fire Insurance Co. Ltd. (“Tokio”) and, with respect to certain sections only, Tokio Marine Holdings, Inc. entered into on October 30, 2018 (the “TMR Stock Purchase Agreement”) (the “TMR Stock Purchase”). The following unaudited pro forma consolidated statement of operations combines the separate historical consolidated statement of operations of RenaissanceRe and the TMR Group Entities after giving effect to the acquisition of the TMR Group Entities, and the assumptions and adjustments described in the accompanying notes to the unaudited pro forma consolidated statement of operations. The unaudited pro forma consolidated statement of operations for the nine months ended September 30, 2019 is presented as if the acquisition of the TMR Group Entities had occurred on January 1, 2018. The historical statement of operations has been adjusted to reflect factually supportable items that are directly attributable to the acquisition of the TMR Group Entities and expected to have a continuing impact on the results of operations of the combined company. The unaudited pro forma consolidated statement of operations gives effect to the gross proceeds of Renaissance’s $400.0 million offering of 3.600% Senior Notes due 2029, which closed on April 2, 2019 (the “Senior Notes”), and the application of $200.0 million of such proceeds to repay indebtedness under RenaissanceRe’s revolving credit facility which was used to fund the purchase price for the TMR Stock Purchase.

The preparation of the unaudited pro forma consolidated statement of operations and related adjustments required management to make certain assumptions and estimates. The unaudited pro forma consolidated statement of operations should be read together with:

In connection with the integration of the operations of RenaissanceRe and the TMR Group Entities, RenaissanceRe has incurred, and anticipates that it may incur additional, nonrecurring charges. RenaissanceRe is not able to determine the timing, nature, and amount of any additional future charges. However, these charges may affect the results of operations of the combined company in the period in which they are incurred.

The unaudited pro forma consolidated statement of operations is provided for informational purposes only. Additionally, the unaudited pro forma consolidated statement of operations is not necessarily, and should not be assumed to be, an indication of the results that would have been achieved had the transaction been completed as of the dates indicated or that may be achieved in the future. In addition, the unaudited pro forma consolidated statement of operations does not give consideration to the impact of possible revenue enhancements, expense efficiencies, synergies or asset dispositions that may result from the acquisition of the TMR Group Entities.

NOTES TO UNAUDITED PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS

Note 1. Pro Forma Basis of Presentation

The unaudited pro forma consolidated statement of operations for the nine months ended September 30, 2019 is based on the historical financial statements of RenaissanceRe and the TMR Group Entities after giving effect to the completion of the acquisition of the TMR Group Entities and the assumptions and adjustments described in the accompanying notes. The unaudited pro forma consolidated statement of operations for the nine months ended September 30, 2019 is presented as if the acquisition of the TMR Group Entities had occurred on January 1, 2019. The unaudited pro forma consolidated statement of operations does not give consideration to the impact of possible revenue enhancements, expense efficiencies, synergies, strategy modifications, asset dispositions or other actions.

RenaissanceRe’s financial statements have been prepared on the basis of accounting principles generally accepted in the U.S. (“U.S. GAAP”) and presented in U.S. dollars (“USD”). TMR AG’s financial statements were prepared in accordance with international financial reporting standards as issued by the International Accounting Standards Board (“IFRS”) and presented in USD. TMR UK’s financial statements were prepared in accordance with generally accepted accounting principles in the United Kingdom (“U.K. GAAP”) and presented in pounds sterling (“GBP”). The unaudited pro forma consolidated statement of operations includes adjustments to (i) convert the financial information of TMR AG and TMR UK to U.S. GAAP, and (ii) translate the historical results of TMR UK to USD using an average spot rate of 1.306 for the pro forma consolidated statement of operations.

The transaction was accounted for under the acquisition method of accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 805 Business Combinations, with RenaissanceRe as the acquiring entity. In business combination transactions in which the consideration given is not in the form of cash (that is, in the form of non-cash assets, liabilities incurred, or equity interests issued), measurement of the acquisition consideration is based on the fair value of the consideration given or the fair value of the assets (or net assets) acquired, whichever is more clearly evident and, thus, more reliably measurable.

Under FASB ASC Topic No. 805 Business Combinations, all of the TMR Group Entities assets acquired and liabilities assumed in this business combination are recognized at their acquisition-date fair value, while transaction costs and restructuring costs associated with the business combination are expensed as incurred. The excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed, if any, is allocated to goodwill. Changes in deferred tax asset valuation allowances and income tax uncertainties, if any, after the acquisition date will generally affect income tax expense. RenaissanceRe is in the process of implementing an integration plan, which will affect how the assets acquired, including intangible assets, are and will be utilized by the combined company.

A final determination of the fair value of the TMR Group Entities assets acquired and liabilities assumed, including the fair value of the identifiable intangible assets and the value of business acquired, was made on March 22, 2019. The Company recognized goodwill of $13.1 million primarily attributable to the excess of the purchase price over the fair value of the net assets of the acquired TMR Group Entities. There were no other adjustments to carried goodwill during the period ended March 31, 2019 reflected on the Company’s consolidated balance sheet at March 31, 2019. The Company recognized identifiable finite lived intangible assets of $11.2 million, which will be amortized over a weighted average period of 10.5 years, identifiable indefinite lived intangible assets of $6.8 million, and certain other adjustments to the fair values of the assets acquired, liabilities assumed and shareholders’ equity of the TMR Group Entities at March 22, 2019.

In connection with the integration of the operations of RenaissanceRe and the TMR Group Entities, RenaissanceRe has incurred and anticipates that additional nonrecurring charges may be incurred. RenaissanceRe is not able to determine the timing, nature, and amount of any additional future charges. However, these charges may affect the results of operations of the combined company in the period in which they are incurred.

The unaudited pro forma consolidated statement of operations is presented solely for informational purposes and is not necessarily indicative of the consolidated results of operations or financial position that might have been achieved for the periods or dates indicated, nor is it necessarily indicative of the future results of the combined company.

Note 2. TMR Group Entities

Certain financial information of the TMR Group Entities, as presented in its interim financial statements, has been reclassified to conform to the historical presentation in RenaissanceRe’s consolidated financial statements and combined for purposes of preparing the unaudited pro forma consolidated statement of operations.

TMR AG’s historical consolidated financial statements are prepared in accordance with IFRS. The consolidated financial statements are presented in U.S. dollars, which is the reporting currency.

TMR UK’s historical financial statements are prepared in accordance with U.K. GAAP. TMR UK’s reporting and functional currency is GBP. For purposes of preparing the unaudited pro forma condensed consolidated statement of operations, TMR UK’s interim historical income statement has been translated into U.S. dollars using an average spot rate of 1.306 for the pro forma consolidated statement of operations.

Unaudited adjustments have been made to convert IFRS and U.K. GAAP, to U.S. GAAP and are noted in Note 3. There are no material intercompany balances or transactions between TMR AG and TMR UK.

Note 3. Unaudited Pro Forma Adjustments

The unaudited pro forma consolidated statement of operations is not necessarily indicative of what the financial position and results from operations would have been had the acquisition of the TMR Group Entities been completed at the date indicated. The unaudited pro forma consolidated statement of operations does not give consideration to the impact of possible revenue enhancements, expense efficiencies, synergies, strategy modifications, asset dispositions or other actions that may result from the acquisition of the TMR Group Entities.

The following unaudited pro forma adjustments result from accounting for the acquisition of the TMR Group Entities. The descriptions related to these unaudited pro forma adjustments are as follows:

Adjustments to the Pro Forma Condensed Consolidated Statement of Operations

The entries include decreasing premiums receivable, assumed and ceded unearned premium and reinsurance balances payable on the pro forma condensed consolidated balance sheet to reflect the gross premiums written due to the TMR Group Entities, net of the related acquisition costs payable by the TMR Group Entities as well as the ceded premiums written due from the TMR Group Entities, net of the related acquisition costs payable to the TMR Group Entities, which would have been recognized at the reinsurance contract inception date by the TMR Group Entities. In the pro forma consolidated statement of operations, there is a related decrease in gross and net premiums written. As the premium and related acquisition expenses are unearned there is no impact to net income related to conforming this accounting policy.
