2. REQUIRED RECONCILIATION DATES 2.1 From time to time, DB shall provide a notice to Client (each, a "Required Reconciliation Date Notice") in which DB represents that, in its good faith belief, DB is required to perform a Data Reconciliation. A Required Reconciliation Date Notice will specify (1) whether such Data Reconciliation shall be performed quarterly or annually and (ii) if applicable, one or more Data Delivery Dates. 3. ONE-WAY DELIVERY OF PORTFOLIO DATA 3.1 Subject to Section 4 below, the following shall apply to all portfolio reconciliations between DB and Client: (a) The Required Reconciliation Date Notice will specify one or more Data Delivery Dates, provided that the first such date will be a day no earlier than the second Joint Business Day following the date on which such notice is given to Client, and provided further that if, prior to the first such date, Client requests one or more different Data Delivery Dates, the relevant Data Delivery Dates will be as agreed between DB and Client. On each Data Delivery Date, DB will provide Portfolio Data to Client (or its agent) for verification by Client. For these purposes, Portfolio Data will be considered to have been provided to Client (and Client will be considered to have received such Portfolio Data) if it has been provided (i) in accordance with the notice provisions set out in the Addendum, or (ii) to a third-party service provider agreed to between the DB and Client for this purpose. (c) On or as soon as reasonably practicable after each Data Delivery Date, and in any event not later than the close of business on the second business day following the Data Delivery Date, Client will review the Portfolio Data delivered by DB with respect to each relevant swap against Client's own books and records and Valuation for such swap and notify DB whether it affirms the relevant Portfolio Data or has identified any Discrepancy. Client shall notify DB of all Discrepancies identif
