We determined that the Department failed to report 6 conferences in FY 2014 and 14 conferences in FY 2015 that were greater than $100,000 in its Annual Report to the Office of Inspector General and on the public website, as required by Federal regulations. The total dollar value of these unreported conferences was $862,881 and $2,822,561 for FYs 2014 and 2015, respectively. In addition, the Department did not always report actual conference costs timely or accurately. We made five recommendations that would improve conference reporting and recordkeeping and ensure the accuracy and timeliness of conference submissions. DHS concurred with all five of our recommendations and has implemented corrective actions, resulting in the resolution and closure of all the recommendations.
