Average

Based on our test results, we found that departments are not reconciling their Chevron accounts which allowed

frequent and reoccuring unusual activity to continue without being detected. We found Chevron accounts often

incurred late charges. We also found one fuel statement that is significantly higher than average.

To determine whether Chevron fuel card accounts are being monitored and reconciled by the departments that

have Chevron accounts.

We tested if the charges for the month were significantly higher than average (We determined that a bill is

significantly higher if it is over 2 standard deviations more than average)
