An audit report found the following:

The required background checks for all new employees were not performed by Human Resources. The corporation had two new sales representatives who committed fraud on their expense reports when they were visiting golf courses across the country.Background checks later were found that they had criminal backgrounds. This loss totaled a $9,051.Additionally, ICE raided the manufacturing facility and found 2 other employees who were illegal aliens who used false social security information to be hired. This hit the local news.

Based on the above answer the following:

cost or problem?

how does the auditor (you) recommend fixing the problem?
