Prior to reading the standard on Material Transactions Substantiation, it is beneficial to review the below sections to gain foundational information:

  1. Accounting Fundamentals Section
  2. Financial Statements Section
  3. Closing Standards and Procedures - Closing Standards Section


This section discusses the elements of the material transactions substantiation process and how it is conducted internally within Indiana University. Information presented below will outline requirements for transaction support, the documentation required to substantiate a transaction, and requirements and best practices related to this process.


Material transactions substantiation is key to ensuring the accuracy of the University financial statements and compliance with external regulatory requirements. Material transaction substantiation at IU, refers to detailed documentation and/or work papers substantiating line-item transactions that exceed the $5 million threshold (NOTE: the threshold does not apply to document total amounts, but to individual transactions). The supporting documentation or substantiation should be detailed enough that a person without extensive knowledge of the transaction can review the support, understand the nature of the transaction, and tie it back to the general ledger detail. Auditors request documentation that supports financial transactions showing why and how a transaction was completed in order to ensure the accuracy, completeness and compliance with all local, state and federal requirements. In order to ensure all fiscal officers and transaction initiators are familiar with the requirements for material transactions substantiation, examples of appropriate support to provide are discussed below.

Importance and Impact of Material Transactions Substantiation

Substantiating material transactions is an important tool for account management and preparation for external audits. Reviewing material financial transactions helps identify transaction errors, inaccurate balances, improper spending, embezzlement, and highlights other negative activity, such as theft or fraud, before balances are finalized for a period-end close. Failure to detect these errors may lead to issues concerning internal controls or the accuracy of the financial statements which impacts future funding from government organizations, creditors, or individual donors. In order to ensure the integrity of an entity’s financial reports, it is important that each entity review and substantiate material transactions on a quarterly basis. By reviewing and substantiating material transactions as part of the quarterly closing procedures, the university can produce reliable and accurate financial statements free from material misstatement that could result in false conclusions. This is important for the university’s externally audited consolidated financial statements as well as internal management reporting for decision making.

Identifying and Substantiating Material Transactions

Documentation is a critical aspect of substantiating financial transactions. To meet the material transaction substantiation requirements, documentation needs to answer the questions of: Who, What, Where, When and Why?

Properly identifying and substantiating material transactions involves:

  • Reviewing line-item detail transactions for amounts $5 million and above
  • Determining and gathering the appropriate supporting documentation (i.e. contracts, written agreements, schedules and invoices) for each material transaction
  • Ensuring transactions are substantiated, supported and answer all of the who, what, where, when and why questions
  • Submitting documentation to University Accounting and Reporting Services at

Transaction Substantiation Process

Examples of types of transactions that need to be substantiated include; accounts receivable, accounts payable, contract and grants, unearned revenue, and state appropriations. Please see the Financial Transaction Substantiation standard for more information. Standard procedures should be in place to ensure entities are reviewing material transactions and submitting the appropriate documentation to University Accounting and Reporting Services at on no less than a quarterly basis. The substantiation process at the account line-item level typically comprises the following steps:

NOTE: The focus of the material transaction substantiation process is to gather information to support the transactions prior to the external audit to aid in streamlining the audit process.

  1. Identify material transactions. Run the Material Transactions Report to identify the unit-level generated transactions that will require supporting documentation be submitted to UARS.
  2. Gather appropriate documentation. Each transaction is required to have the following:
    1. A copy of the original source document such as an agreement, contract or grant documentation, analysis conducted, calculations completed, emails, memos, receipts, etc. that supports the transaction).
    2. The KFS document number (i.e, invoice, cash receipt, ACH).
    3. An appropriate storage index which is retrievable by KFS document and date in the event of an audit. Fiscal officers are responsible for ensuring that substantiation is maintained for their accounts.
  3. Examples of Who, What, When, Where, & Why Questions as it relates to documentation
    1. Who: Who completed the transaction and was involved in the transaction? What parties? Anyone outside of IU?
    2. What: What was the reason for the transaction?
    3. Where: Where did the transaction originate from if not KFS? Was it from an outside system?
    4. When: When did activity that caused transaction take place? For example, when were services provided or items purchased? Is the activity taking place over multiple reporting periods or fiscal years?
    5. Why: Why was the entry booked the way it was? For example, was there a specific methodology or calculation completed to support the transaction amount. The detailed calculation should accompany the documentation. Why was this account and object code used? It should be evident from the documentation why a particular account and object code were used.
  4. Submit documentation. Combine all supporting documentation into one Excel file and submit to If a unit has a screenshot or a PDF, they can insert it on a tab of the Excel workbook.
