2 Risk Assessment Criteria Account Risk Criteria 1 Size and Composition 2 Transaction Volume 3 Transaction Complexity 4 Subjectivity and Estimation High (Points 3) Account balance greater than $10 million Multiple transactions per day Transactions are complex in nature (i.e. complex calculations, requiring significant financial disclosures, complex accounting guidance associated with account, etc.) 75% of the account balance is based on subjectivity or estimates. 5 Inherent Risks Historically a high risk account 6 Overall Score Total Score of 12 or greater Moderate (Points 2) Account balance less than $10 million but greater than $5 million More than 100 transactions per year but less frequent than one transaction a day Majority of the transactions are noncomplex. However, some transactions require additional attention due to their complexity. Greater than 10% and less than 75% of the account balance is based on subjectivity or estimates. Historically a moderate risk account Total Score less than 12 but greater than 8 Low (Points 1) Account balance less than $5 million Less than 100 transactions per year Transactions are routine in nature.

6 Purchase to Pay Process: Narrative Purchase to Pay Supporting Application: Application XYZ This document provides a description of the Purchase to Pay Process as performed by as of 6/30/XXXX. The following processes form part of the Purchase to Pay cycle at. New Vendor Setup: This is a prerequisite to the Purchase to Pay Process (P2P), since one cannot start the process without having vendors set up on the system. Purchasing (Purchase Request (PR) and Purchase Orders (PO); PR - This initiates the P2P process, since anyone in the company can request an item to be used in his or her daily activities. PO - This is where the purchasing department transforms related purchase requests to orders. Receiving: This is where the requestor and/or receiving clerk receives the goods ordered. Processing Invoices: This is where receives the vendor s invoice, performs a verification process on the invoice, and makes it ready for payment. Payments: This is where the vendor s payment is created and delivered. The account payable (AP) is maintained here. Update the General Ledger (GL)/Accrual: This is where the above transaction is reflected in the GL. New Vendor Setup Inputs: Vendor information (name, address, bank details, payment terms, discounts, matching principal, accounting, etc.) Output: Vendor in system A formal process exists to add or modify vendors. Note that Application XYZ does not permit the deletion of vendors; it will only allow a vendor to be altered or disabled. This process consists of the following activities: The Supplier Maintenance Form is filled out by the buyer. This form details the vendor s name, address, bank details, payment terms, discounts, matching principal, accounting information, etc. The form must be signed by the buyer s supervisor, who checks the details for accuracy. The form is then sent to the AP department where it is reviewed and entered into the system. Additional Notes: Application XYZ does not allow duplicate supplier names to reside in the system. EAGLE Training Program 6

7 Purchase to Pay Process: Narrative Purchasing Purchase Requests (PR) Inputs: Vendor in system, item to be purchased, quantity, delivery date and location Output: Approved purchase request A PR can be created by any Application XYZ user. This process typically consists of the following activities: Create PR using the system. The requestor enters the item needed, quantity, delivery date and location. The system routes the PR to the requestor s supervisor, who reviews the request for appropriateness. Based on the above review, the PR is approved or disapproved. If approved, the PR goes to Purchasing for creation of a PO. If disapproved, the requestor gets a notification for correction from the approver. Additional Notes: Application XYZ automatically (real-time) routes all PRs for approval upon creation. Every system user is assigned an approver to approve his or her requests (defined in HR hierarchy). Auto-numbering for purchase requisitions is being used. Narratives for remaining processes have been intentionally omitted. EAGLE Training Program 7

Preventive or Detective? Frequency of Control Activity Existence Unauthorized disbursements are made and recorded. Check printing is restricted to the AP Manager and the Corporate Controller who authorize the check run by its activation. These individuals do not have update access rights to the AP application other than to perform this function. AP10 XYZ Automated Preventive Continuous Payments Completeness Existence Unauthorized disbursements are made and recorded; cash disbursements are not recorded accurately. All checks are processed through an integrated check-writing function in Application XYZ. Checks can only be processed against vouchers already existing in the AP system and for the same amount (i.e. no changes can be made to amounts during the check processing). Checks can only be processed to payees recorded in the vendor master file (i.e. no input of temporary payee data). AP11 XYZ Automated Preventive Continuous Update to G/L Completeness Existence Valuation Rights & Obligations Presentation & Disclosure Transactions do not accurately update from Accounts Payable system to the General Ledger system, resulting in misstatements of the financial statements. General Ledger updates from Accounts Payable are controlled by integrated XYZ modules which use predefined control accounts and fields which ensure that postings are in balance and include complete data. Batches containing errors will not post to the general ledger and require resolution by the AP Supervisor prior to posting. General ledger accounts and accounts payable subsidiary ledgers are reconciled on a monthly basis by the AP Supervisor. Reconciliations are reviewed by the Financial Reporting Controller.

11 Purchase to Pay Process: Walkthrough Process: Sub-process: Supporting Application: Title: Purchase to Pay New Vendor Setup Application XYZ New Vendor Setup Walkthrough This walkthrough template assists in documenting our understanding of the design of controls. We document the procedures performed, evidence obtained and conclusions as to the effective design of the underlying controls and whether the controls have been implemented. Process Owner Name / Title: Jane Smith, AP Buyer Interview Date: January 1, 20XX Selection: South Telephone (Vendor #101) Procedures Performed: To perform a walkthrough of the New Vendor Setup process, we obtained the Vendor Report listing all current vendors as of the walkthrough date. We randomly selected vendor #100, South Telephone. We then performed the procedures below. The Supplier Maintenance Form is filled out by the buyer. This form details the vendor s name, address, bank details, payment terms, discounts, matching principal, accounting information, etc. -Walkthrough procedures: We obtained the Supplier Maintenance Form for South Telephone vendor and noted that all the form details were filled out (refer to w/p XX.X). The Supplier Maintenance Form must be signed by the buyer s supervisor, who checks the details for accuracy (Control AP1). -Walkthrough procedures: We noted the approval by the buyer s Supervisor on the Supplier Maintenance Form (refer to w/p XX.X). The Supplier Maintenance Form is then sent to the AP department where it is reviewed and entered into the system (Control AP2). -Walkthrough procedures: We noted the form details including the vendor s name, address, bank details, payment terms, and discounts and agreed these to the system (refer to w/p XX.X). Application XYZ does not allow duplicate supplier names to reside in the system (Control AP3). -Walkthrough procedures: We obtained a listing of suppliers report from the system and noted that our selected vendor, South Telephone, resides within the system. We requested that the Buyer enter the same vendor name into the system. We noted that the system appropriately rejected the vendor (refer to w/p XX.X). EAGLE Training Program 11

12 Purchase to Pay Process: Walkthrough Vendor maintenance is performed by the AP department and limited to supervisors. Role-based security is utilized in Application XYZ, such that individuals having access to perform vendor maintenance do not also have access to perform other AP functions such as processing vouchers and printing checks (Control AP4). -Walkthrough procedures: We obtained a user access log for Application XYZ for vender maintenance and noted that there are excessive users with access. Additionally, we noted that a few of the users with access to vendor maintenance had the ability to perform other AP functionality (refer to w/p XX.X; also refer to Issue Summary Log for details on the exception noted).

16 Purchase to Pay Process: Issue Summary Log Issue Summary Log June 30, 20XX Process - Sub process Control Control Reference 1 Purchase to Pay - New Vendor maintenance is AP4 Vendor Set-Up performed by the AP department and limited to supervisors. Role-based security is utilized in Application XYZ, such that individuals having access to perform vendor maintenance do not also have access to perform other Accounts Payable functions - process vouchers and print checks. Issue Risk/Implication Recommendation Managements Response We obtained a user access log for Application XYZ for vendor maintenance and noted that there are excessive users with access. Additionally, we noted that a few of the users with access to vendor maintenance had the ability to perform other AP functionality. Issue was noted during walkthrough. Unauthorized or incorrect changes are made to the vendor master file, increasing the risk of fraudulent payment transactions. We recommend that management review the listing of AP users and their access rights in detail to help ensure that access to perform vendor maintenance be restricted to only AP supervisors. Additionally, we recommend that those AP supervisors be restricted from performing other AP functions. A listing of users with access to perform vendor maintenance will be reviewed for appropriateness by Joe Controller and restricted only to AP supervisors. Additionally, a segregation of duties review will be performed to further restrict access within the AP department. 2 Purchase to Pay - Processing Invoices All invoices are approved by the AP Clerk prior to validation. AP8 For two of the 40 selections, no evidence of the AP Clerk's approval existed. Issue was noted during testing. Invoices are posted to accounts payable without proper authorization, increasing the risk of fraudulent transactions or misstatements of accounts payable. We recommend that employees need to be reminded of the agency policy regarding documentation of their review. We will review the policy around approval of invoice documentation and remind employees of the importance of signing off as evidence of approval. EAGLE Training Program 16
