DOL Audit and closing letter

Group:

I may be going crazy given this day and age we are living in. 

I thought I read on one of the older benefits link.com messages/posts that the DOL - in some investigations - will not issue a closing letter but still close out their audit. 

Could this occur in a small case DOL Audit for an esop with less than $5k value?

Or did I misunderstand the posting that the DOL Audit will always include some form of closing agreement or determination? 

Thank you in advance. 

In my experience, this happens sometimes when there is a self correction, and both parties are trying to prevent the application of 502(l).
