| | - | -------------------------------------------------------------------------------------------------------------------------------
| |  | Implemented automated and manual controls for our primary
    financial system to monitor unauthorized password changes;       
|
| |  | Developed a segregation of duties matrix for our primary
    financial system that documents existing role
    assignments; and
|
| |  | Implemented an accounting policy that requires a higher level of
    review of non-routine transactions.                       





| |   |                                                                                                                                                                                           
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |  | Performed an in-depth analysis of the companys primary
    financial accounting system to examine existing functional
    access to identify any potentially incompatible duties.        
|
| |  | Enhanced the segregation of duties matrix for our primary
    financial accounting system based on the in-depth analysis of
    user access.                                              
|
| |  | Modified the primary financial accounting system to eliminate or
    modify potentially conflicting functionality.                                                                        
|
| |  | Implemented a process to evaluate all new user access requests
    against segregation of duties matrices to ensure no new
    conflicts are created for our applications described above.
|
| |  | Separated security administration rights from system update
    capabilities for our applications described above.                                                                        
|
| |  | Implemented monitoring procedures to monitor activities of
    security administration roles for our applications described
    above.                                                    
|
| |  | Improved communications to establish the expectation that
    non-routine transactions must be communicated to ensure timely
    identification and thorough review of transactions.      
|
| |  | Established periodic business unit meetings to discuss and
    review non-routine transactions.
