Jason and a multidisciplinary team of forensic accountants, investigative research analysts, and economists performed independent forensic audits of the accuracy and completeness of proposed abatement cost components and the thousands of inputs and outputs underlying complex economic models used to estimate abatement periods and projected costs. The analyses required evaluation of both the functional relationships among the underlying data points and the viability of the economic models themselves, including whether the models produced logically and definitionally supportable results. The reviews additionally involved analysis of disparate datasets and public health sources, including ARCOS, TEDS, NSDUH, and CDC Wonder, as well as subsequent iterations of the models developed by plaintiffs’ experts in response to deficiencies identified during the review.

The investigation involved the review of large volumes of structured and semi-structured operational data across numerous locations and personnel records to identify patterns indicative of systemic misconduct, improper billing practices, and potential control deficiencies.
