Former Exelon Chief Compliance Ethics Officer Kristopher Keys took the stand as a witness on Tuesday.
He discussed three buckets in place at Exelon: operational controls, compliance and regulatory controls, and financial controls.
During his testimony, there was great discussion about the internal Exelon's code of business conduct.
From 2011 to 2019, Exelon had a Code of Business conduct that applied to ComEd employees; however, it was revised from 2015 to 2019.
Keys explained that the code of conduct was to prevent any falsification of data and serve as a reminder of the expectation that that behavior does not occur.
The code advises employees to use third parties like vendors.
Keys adds that ComEd employees had to undergo any training and complete a yearly certification where they were required to report any potential violations.
Keys agreed that Anne completed and certified that she had complied with the code of conduct; John Hooker did as well until he retired.
