The Trustees of Princeton University’s Costs Incurred and Claimed for Fiscal Years 2016 Through 2019 Under Contract No. DE-AC02-09CH11466
This audit was performed by CohnReznick LLP (CohnReznick) on behalf of the Department of Energy Office of Inspector General. CohnReznick audited The Trustees of Princeton University’s costs incurred and claimed for fiscal years 2016 through 2019 at Princeton Plasma Physics Laboratory, under management and operating contract No. DE-AC02-09CH11466.
The audit’s objective was to determine if costs charged to Department contract No. DE-AC02-09CH11466 for fiscal years 2016 through 2019 were allowable, allocable, and reasonable in accordance with contract terms, applicable laws, and regulations.
CohnReznick performed the audit in accordance with generally accepted government auditing standards.
CohnReznick identified two control deficiencies related to inadequate timekeeping controls and lack of supporting documentation showing cost or price analysis. Additionally, CohnReznick considered approximately $1.5 million in subcontractor costs unresolved pending audit and reported two qualifications that may have impacted the results of the audit if the related information had been received and evaluated.
CohnReznick made two recommendations. The Office of Inspector General also recommends that the contractor coordinate with the contracting officer to address the unresolved costs identified in this report. If the issues identified are fully addressed, it should help ensure that costs charged to the Department are allowable, allocable, and reasonable in accordance with contract terms.
The Trustees of Princeton University withheld comment pending discussion with the contracting officer.
