Report on Internal Control and on Compliance 
Financial statement finding 2024-01
County’s deficiencies in its process for managing and 
documenting its risks may put its operations and IT systems 
and data at unintended and unnecessary risk of potential 
harm
County should: 
Ask responsible officials and management for input on policies and 
procedures for managing risk
Implement policies and procedures to effectively manage IT-related risks
Evaluate and manage the risks of holding sensitive information by identifying, 
classifying, and inventorying the information

Report on Internal Control and on Compliance 
Financial statement finding 2024-02
County’s control procedures over IT systems and data were 
not sufficient, which increases the risk that the County may 
not adequately protect those systems and data
County should: 
Monitor employees’ adherence to IT policies and procedures
Restrict access to its IT systems and data
Configure IT systems securely and manage system changes
Secure IT systems and data

Report on Internal Control and on Compliance 
Financial statement finding 2024-03
County’s initial financial statements contained a $6.6 million 
inventory misstatement, which increased the risk that those 
relying on the reported financial information could be 
misinformed 
County should: 
Ensure the financial statements are accurate and prepared in accordance 
with GAAP
Ensure physical inventory counts and valuations are accurate and agree to its 
inventory management system
Ensure employees responsible for physical inventory counts follow 
County policies

Report on Internal Control and on Compliance 
Financial statement finding 2024-04
County School Superintendent’s Office risks receiving more 
or less State funding than statutorily allowed to support 
juvenile detention center education program operations 
because it did not accurately report program operations to 
the Arizona Department of Education (ADE) 
County should: 
Develop a process for separating program operations from the 
accommodation school or inform ADE it is not separating program operations
Ensure the program receives the correct statutory funding

Single Audit Report
Federal compliance finding 2024-101
County Human Services Department failed to report $953,103 
in subawards it made to 4 subrecipients for the Community 
Development Block Grants/Entitlement Grants 
County should:
Immediately report on the Subaward Reporting System the required 
information for its subawards
Follow the grant policies and procedures for reporting subaward 
actions equaling or exceeding $30,000 no later than month-end of 
the following month
