Re:   Validus Holdings, Ltd.
Form 10-K for the Fiscal Year Ended December 31, 2010
Filed on February 18, 2011
File No. 001-33606

Dear Mr. Rosenberg:

     Validus Holdings, Ltd. (the “Company” or “Validus”), hereby submits responses to the comments of the Staff regarding the above-referenced filing (the “Form 10-K”) as set forth in your letter dated June 30, 2011 (the “Comment Letter”).

     Set forth below are the Staff’s comments contained in the Comment Letter and immediately following each comment is the Company’s response.

     The Company is available at your convenience to discuss any comments or questions. Thank you in advance for your consideration.

Management’s Discussion and Analysis of Financial Condition and Results of Operations
Loss and Loss Expenses, page 70

     1. You state the following on page 71 “Potential losses in excess of the estimated ultimate loss assigned to a contract on the basis of a specific review, or loss amounts from contracts not specifically included in the detailed review are reserved for in the reserve for potential development on notable loss events.” Please tell us the amount recorded as of December 31, 2010 in your balance sheet and the amounts reflected in each period presented in your consolidated statements of operations and comprehensive income for these potential losses, separately for those in excess of the estimated ultimate loss assigned to a contract on the basis of a specific review and those from contracts not specifically included in the detailed review. Further, tell us how the notion of potential is consistent with your accounting policy and how your accounting for these potential losses complies with ASC 944-40-25.

     Response: The Company acknowledges the Staff’s comment with respect to the reserve for potential development on notable loss events. As disclosed on page 93 of the Form 10-K and included below, the amount recorded as at December 31, 2010 in the balance sheet in the reserve for potential development on 2010 notable loss events is $33.4 million.

     ‘In the first quarter of 2010, the Company incurred $19.2 million for a reserve for potential development on 2010 notable loss events, which in the second quarter of 2010 was allocated to development on the Chilean Earthquake. In the second quarter of 2010, the Company made a provision for losses and loss expenses of $20.0 million in the reserve for development on 2010 notable loss events. In the third quarter of 2010, the reserve was increased by an additional provision of $30.0 million. In the fourth quarter of 2010, no further provisions were made and the Company allocated $16.6 million of the reserve for potential development on 2010 notable loss events to development on the New Zealand Earthquake. Therefore, as at December 31, 2010, the reserve for potential development on 2010 notable loss events is $33.4 million.’

     The Company did not record an amount in respect of the reserve for potential development on notable loss events prior to January 1, 2010.

     The Company notes that under the requirements of ASC 944-40-25 the Company’s obligation is to provide its best estimate of losses in the aggregate as at each balance sheet date. The concept of an ‘actuarial central estimate’ of a population of claims being different from the sum of the ‘actuarial central estimates’ of each individual claim is accepted in the actuarial profession. As such, the requirement for a reserve provision in respect of development on notable loss events in a quarter is a function of:

          (a) The number of significant events occurring in that quarter; and

          (b) The complexity and volatility of those events.

-2-

     The evaluation of each quarter’s requirement for a reserve for development on notable loss events takes place as part of the Company’s quarterly evaluation of its reserve requirements. It is not directly linked in isolation to any one significant /notable loss in the quarter and therefore it is not ‘assigned to a contract on the basis of a specific review.’

     The provision for the reserve for development on notable loss events is evaluated by the Company’s in-house actuaries as part of their normal process in the setting of indicated reserves for the quarter.

The guidance in ASC 944-40-25-2 specifies that:

‘The estimated liability for unpaid claims includes the amount of money that will be required for future payments on both of the following:

     (a) Claims that have been reported to the insurer; and

     (b) Claims relating to insured events that have occurred but have not been reported to the insurer as of the date the liability is estimated.’

     This provision therefore represents a reserve for development on known notable loss events occurring prior to the balance sheet date which is required to ensure sufficiency of reserves in the aggregate as required under ASC 944-40-25-2 (b).

     On page 51 of the Form 10-K, under ‘Critical Accounting Policies and Estimates’ the Company discloses the process for establishing the reserve for potential development on notable loss events as highlighted below:

‘Reserve for Losses and Loss Expenses. For insurance and reinsurance companies, a significant judgment made by management is the estimation of the reserve for losses and loss expenses. The Company establishes its reserve for losses and loss expenses to cover the estimated remaining liability incurred for both reported claims (“case reserves”) and unreported amounts (“incurred but not reported” or “IBNR reserves”). For insurance and reinsurance business, the IBNR reserves include provision for loss incidents that have occurred but have not yet been reported to the Company as well as for future variation in case reserves (where the claim has been reported but the ultimate cost is not yet known). Within the reinsurance business, the portion of total IBNR related to future variation on known claims is calculated at the individual claim level in some instances (an additional case reserve or individual claim IBNR). Within the insurance business, the provision for future variation in current case reserves is generally calculated using actuarial estimates of total IBNR, while individual claim IBNR amounts are sometimes calculated for larger claims. During 2010, given the complexity and severity of notable loss events in the year, an explicit reserve for development on 2010 notable loss events was included within the Company’s IBNR reserving process. As uncertainties surrounding initial notable loss events develop, it is expected that the

-3-

reserve will be allocated to specific notable loss events.’

     The methodology that the Company applies is to provide for losses below its defined event threshold by actuarial methodology (attritional losses). The Company provides for losses above its defined event threshold by accumulating loss information from modeling agencies, where possible, publicly available sources and information contained in client reports and estimates. The loss information is applied to the Company’s book of in-force contracts to establish an estimate of the Company’s ultimate exposure to the loss event. The balance sheet and income statement amounts in respect of the reserve for development on notable loss events indicated above represent both: (1) loss reserves in excess of the estimated ultimate loss assigned to affected contracts on the basis of a specific review; and (2) loss reserves related to affected contracts that were initially not considered to be affected during our detailed review. The reserve amount is determined in consideration of both components, rather than separately for each component.

     As a reinsurer, the Company’s ‘event driven’ reserving process is more difficult than for a direct insurance writer due to the fact that (i) reinsurance contracts typically cover multiple events and (ii) there is an extended time lag from when a loss event occurs to when specific loss information becomes available to the reinsurer. Historically, the difficulty in estimating large complex loss events has been clearly demonstrated in the reinsurance industry. Set forth in Exhibits 1.1 and 1.2 attached hereto are analyses of significant 2005 and 2008 catastrophe events which illustrate the changes in our peer group companies’ initial publicized loss estimate to that which is recorded in such companies’ respective results upon the passage of time. The Company respectfully suggests that the adverse development with respect to these complex events not only demonstrates the prudence in establishing a reserve for potential development on notable loss events but also demonstrates that establishing such a reserve is in compliance with both the letter and spirit of ASC 944-40-25.

Notes to Consolidated Financial Statements
10. Reserve for Losses and Loss Expenses, page F-25

     2. Please refer to the line item “total net paid losses” in the table reconciling the reserve for losses and loss expenses beginning of the year to the end of the year. Provide us proposed disclosure to be included in future filings showing, for each period presented, separate disclosure of payments of claims and claim adjustment expenses attributable to insured events of the current fiscal and to insured events of prior fiscal years as specified in ASC 944-40-50-3c.

     Response: The Company acknowledges the Staff’s comment and will include the following disclosure in the Company’s Form 10-K for the year ended December 31, 2011:
