the revelation." In a separate but related action against Rolls-Royce, the US Department of Justice (DOJ) claimed that Rolls-Royce had paid more than US$11M in commissions, aware that some of the funds would be used to bribe officials at Thai energy company PTT and its subsidiary PTT Exploration and Production (PTTEP). The payments were made from 2003-2013 and related to contracts for equipment and after-market products and services. Admitting its guilt, Rolls-Royce paid US$170M to settle the case. PTT vowed to investigate. Subsequently, PTT Chairman and CEO Tevin Vongvanich said that the company was unable to find anyone who "allegedly took bribes".

The Bangkok Post estimates the value of Prawit's 16 known timepieces at "...up to 22M[illion baht]" (US$685,000). Critics have questioned why the NACC appears to be giving Prawit special treatment and ignoring its standard operating procedures in his case.
