Written Comment (March): If the intent of this section is the same as (b), then 

we ask then the NIGC ensure that the term “reviewed” is consistent with the term 

“audit”. If that is not the intent, then we ask the NIGC to clarify the purpose, 

scope and intent of the term “reviewed” in this section 

Response: Although NIGC believes that the introductory sentence in (b) makes it 

clear that “audits” of the specified areas are required, in the interest of clarity, we 

agree to replace “reviewed” with “audited” in (b) (1) and (b) (3). 

Revised proposal as a result of written comment:
