gaming operations? 

(a) Internal audit personnel. (1) For Tier B gaming operations, a separate internal audit 

department must be maintained. Alternatively, designating personnel (who are 

independent with respect to the departments/procedures being examined) to perform 

internal audit work satisfies the requirements of this paragraph. 

(2) The internal audit personnel shall report directly to the Tribe, Tribal gaming 

regulatory authority, audit committee, or other entity designated by the Tribe in 

accordance with the definition of internal audit in §542.2. 

Note: (b) (1) and (2) have been updated for consistency with final proposals. 

(b) Audits. (1) Internal audit personnel shall perform audits of all major gaming areas of 

the gaming operation. The following shall be reviewed at least annually: 

Comment (July): Replace “all areas” with “gaming areas”. 

Response: Agree to strike “all areas” as overly inclusive. Disagree to replace 

with “gaming areas” as audit standards for areas that could be classified as nongaming are included in this subsection, including cage, credit, information 

technology, and accounting. 

Comment (July): Replace with “Internal audit personnel shall perform audits of 

the following areas at least annually.” 

Response: Agree. However, recommend modification of (b), (b) (1), and (b) (2) 

to reduce repetition and incorporate the comment into the standards. 

(b) Audits. Internal audit personnel shall perform audits of all major gaming areas of 

the gaming operation. 

(1) The following areas shall be reviewed at least annually:

(xi) Any other internal audits as required by the Tribe, Tribal gaming regulatory 

authority, audit committee, or other entity designated by the Tribe. 

(2) The following areas shall be reviewed at least semi-annually: 

(i) Table games, including but not limited to, computer applications, fill and credit 

procedures, table inventory forms, computer generated documentation, playing 

cards and dice, plastic cards, supervision, table game analysis, accounting/auditing, 

marker credit play, named credit instruments, call bets, rim credit and foreign 

currency; and

(ii) Gaming machines, including but not limited to, standards for gaming machines, 

computer applications, jackpot payouts, gaming machine fills, short pays and 

accumulated credit payouts, promotional payouts, department funds, EPROM’s, 

theoretical and actual hold, hopper content standards, player tracking, in-house

access cards and smart cards. 

(3) In addition to the observation and examinations performed under paragraph (b)(1) of 

this section, follow-up observations and examinations shall be performed to verify that 

corrective action has been taken regarding all instances of noncompliance cited by 

internal audit, the independent accountant, and/or the Commission. The verification shall 

be performed within six (6) months following the date of notification. 

Comment (July): Add a statement that semi-annual testing satisfies the 6 month 

follow up requirement.

6-30-10 Version 

Page 7 of 10 
Comment (October): Replace “date of notification” with “end date of the half 

year during which the audit was performed”. 

Comment (October): Add “or the end date of the half year during which the 

audit was performed” as an alternative to “date of notification”. 

Response: Disagree. The half year concept as described by the commenter is 

difficult to define in a way that will be readily understood. Six months from 

notification provides sufficient time for performance of follow-up procedures, and 

for design and implementation of compliant procedures by management.

However, staff remains receptive to suggestions of the committee. 

 

Comment (October): Move (b) (3) to follow (b) (1). 

Response: Agree. (b)(2) then becomes (b) (3). 

(2) (3) In addition to the observation and examinations performed under paragraph (b)(1) 

of this section, follow-up observations and examinations shall be performed to verify that 

corrective action has been taken regarding all instances of noncompliance cited by 

internal audit, the independent accountant, and/or the Commission. The verification shall 

be performed within six (6) months following the date of notification. 

(3) (2) The following areas shall be reviewed at least semi-annually: 

Written Comment (March): If the intent of this section is the same as (1), 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: 

(3) (2) The following areas shall be reviewed audited at least semi-annually:

and counts to satisfy the internal audit observation requirements and independent 

accountant tests of controls as required by the American Institute of Certified Public 

Accountants guide.
