From the Executive Summary: "The Department of Homeland Security (DHS) hosts or sponsors conferences to enhance its mission. These conferences bring DHS employees and stakeholders together to share information, deliver education or training, and coordinate and collaborate with other Federal and non-Federal stakeholders on common issues or goals. According to DHS, during fiscal year 2012, DHS components hosted or sponsored 35 conferences exceeding $100,000 at a total cost of $7.5 million. We conducted this audit as a follow-on to our prior report 'DHS' Policies and Procedures Over Conferences', OIG-13-96, to determine whether the DHS conference spending was appropriate, reasonable, and necessary."
