Management’s Annual Report on Internal Control Over Financial Reporting 39
Management’s Responsibilities
Management is responsible for establishing and maintaining adequate internal 
control over financial reporting for MGM MIRAGE (a Delaware corporation) and
subsidiaries (the “Company”).
Objective of Internal Control Over Financial Reporting
In establishing adequate internal control over financial reporting, management has
developed and maintained a system of internal contr ol, policies and procedures
designed to provide reasonable assurance that information contained in the accom-
panying consolidated financial statements and other information presented in this
annual report is reliable, does not contain any untrue statement of a material fact or
omit to state a material fact, and fairly presents in all material respects the financial
condition, results of operations and cash flows of the Company as of and for the
periods presented in this annual report. Significant elements of the Company’s
internal control over financial reporting include, for example:
• Hiring skilled accounting personnel and training them appr opriately;
• Written accounting policies;
• Written documentation of accounting systems and pr ocedures;
• Segregation of incompatible duties;
• Internal audit function to monitor the effectiveness of the system of 
internal control;
• Oversight by an independent Audit Committee of the Board of Directors.
