We were engaged by counsel for a Fortune 100 financial services company specializing in the development and management of retirement products. The scope of the engagement included the extraction, conversion, and loading of more than 2 billion financial records from legacy mainframe systems during an 11-year period (beginning in the early 1980s). Our team recreated historical data layouts to correctly interpret and reconcile the restored data to contemporaneous financial statements. Economic and valuation experts then used the data to prepare a multi-billion-dollar valuation claim.
