Eugene is a pretty large business with an income of 100's of millions.  Any  business with revenues the magnitude of Eugene's would have a professional Auditor.   $400K is not even 1/10th of 1% of Eugene's budget.
Given the impotence of our Eugene's city council, we do not even have political accountability in Eugene.  It is literally mad to allow our all-powerful city manager to be financially unaccountable as well.
