RBSA Accounting
Recording Revenues
RBSAs have specific practices regarding the bookkeeping of revenues in relation to internal sales to grants and contracts, or sales to external customers. Selecting the wrong account code has implications for CU鈥檚 financial reporting.
| Fund | Customer Type | Account Description/Code | When to use |
| 28 | Internal - Non Sponsored Project | 380100 鈥 Service Center 鈥 IN REV | When receiving revenue from a non-sponsored project speedtype (Fund 10, 11, 26, 34, etc.) (i.e., performing DNA analysis for bone exhibit from the 麻豆免费版下载Museum of Natural History) |
| 28 | Internal - Sponsored Project | 380101- IN Sales to Grants/Contracts | When receiving revenue from a sponsored project (Fund 30, 31, 33, and 12, 22, and 32) (i.e., providing clean room usage to the department of Physics) |
| 28 | External - Federal | 325341- ISU Sales 鈥 RBSA EXTFED CUST | When receiving revenue from a federal agency (i.e., NREL wants to use a core facility to fabricate samples) |
| 28 | External 鈥 Non-Profit | 325342 鈥 ISU SALES 鈥 RBSA EXTNP CUST | When receiving revenue from an external customer considered non-profit, like a city government, another higher education institution. (i.e., analyzing soil samples from Colorado State University) |
| 28 | External - Corporate | 325343 鈥 ISU SALES 鈥 RBSA EXTCORP CUST | When receiving revenue from an external customer considered a corporation (i.e., providing economic consulting for Odell Brewing Company) |

Recording Expenses
Per policy guidelines, you should allocate expenses with the purpose of the expense. For example, a blender from Target may not seem like a reasonable research supply but it may be needed to process samples. Additional information is needed from the department at the time of purchase to adequately document the expenditure.
The Office of University Controller (OUC) has a听 that lists all available expense account codes. If you鈥檙e not sure what expense code to use, you can always reach out to your听campus accountant for guidance.
Note: Expense Account Codes range between 400000 - 989999
Depreciation Expense
Depreciation transfer spreads the cost of equipment over its useful life, helping stabilize service rates. It鈥檚 optional, but departments must commit to using or not using it consistently.
- Purpose: Build a reserve to support future equipment needs.
- Use of Funds: Funds can be accessed before the depreciation period ends and used for:
- Replacing equipment (including newer or different models)
- Maintenance and repairs
- Service contracts or other related costs
- Flexibility: Funds aren鈥檛 tied to the original equipment鈥攄epartments can upgrade to current technology or invest in other necessary instruments.
Depreciation expense on an RBSA can only be recorded if the following is true:
- Equipment is to be used for RBSA services
- Equipment at the time of purchase is greater than $5,000 and has been tagged with a 麻豆免费版下载identity sticker.
- Depreciation is listed on the RBSA rate sheet.
- Equipment has not been fully depreciated and has established annual depreciation in PeopleSoft Finance.

Recording depreciation expense on an RBSA cannot be considered for the following:
- Equipment has exceeded its depreciable life and is considered by university accounting standards to be fully depreciated
- Using manufacturer standards for recording depreciation. Only the CCO determined depreciation schedule in PeopleSoft Finance can be used.
- Using calculations developed by the lab/PI to lower depreciation expense, or inflate the useful life of equipment beyond CU鈥檚 expected useful life determination.
- Any portion of the equipment costs that were borne or donated by a federal fund source
If you have any questions regarding the depreciation of equipment, you can contact听property@colorado.edu for assistance. More information for recording deprecation can also be found on听Ch. 13 of the Departmental Financial Management Guide.
Recording Depreciation
Scenario 1: Equipment is bought outside the RBSA. ex. Faculty Startup/ICR
When recording听depreciation听in your RBSA, it鈥檚 important to account for the听percentage of time the equipment is used specifically for RBSA activities.
If a piece of equipment purchased听on a Fund 10 speedtype, such as a faculty startup, is used听75% of the time for non-RBSA work and听you determine that 25% of the time the machine will be used is for the RBSA, then听only 25% of the equipment鈥檚 annual depreciation听can be allocated to the RBSA.
For example:
Let鈥檚 say the equipment鈥檚听annual depreciation expense is $2,000听from PeopleSoft Finance:
Only听$500听($2,000 脳 0.25) can be allocated to the RBSA.
Scenario 2: Equipment is bought using funds from the RBSA
If a piece of equipment is purchased with funding from the RBSA at 100%, then the equipment should be depreciated using the depreciation schedule from PeopleSoft Finance.
Depreciation Transfer
Depreciation is not booked as an expense to an RBSA in the Finance System general ledger. However, a cash transfer using 995106 鈥 Voluntary Cash Transfer in ISC Depreciation听and 997106 鈥 Voluntary Cash Transfer Out ISC Depreciation听provides the same effect on fund balance. More information about Depreciation Transfers can be found on听Chapter 13 of the Departmental Financial Management Guide. For additional guidance, please contact your听campus accountant.听
Unallowable, Inappropriate, and Sensitive Expenses
Like any other funds on campus, PI鈥檚 and their units are expected to be good stewards of university funding. RBSAs are no exception, and it is essential to be mindful of the expenses allocated to an RBSA.
Unallowable Expenses
Since RBSAs may, during their operations, provide goods and services to sponsored projects supported by federal funds, it is important to be aware of what costs are permissible in billing rates for internal/federal customers.
Chapter 13 of the Departmental听 Financial Management Guide outlines costs that are unallowable to RBSA鈥檚.
Inappropriate Expenses
While some costs may be allowable on other fund types, like a general or discretionary fund, it might not be the same for RBSA activities and may be deemed inappropriate. A common misconception is that the department can use money generated by an RBSA for other purposes, like official functions or covering overages for travel on a sponsored project. This is not necessarily true. The money generated by the RBSA should only be used to support that RBSA鈥檚 activities and should not be used for other activities.
Exception:
If an RBSA generates revenue from an external customer, after its expenses are covered the external profit can be transferred to another Fund 29 to be used for other University approved expenses, such as official functions, travel overages, or conference registration fees for conferences unrelated to the RBSA or can be transferred to the RBSA Fund 78 to be used for later RBSA operations.
Caveat:
If an RBSA generates revenue from an Internal/Federal customer, and after covering its expenses, has a surplus, the surplus can only be used for RBSA activities it was generated for. The surplus can be earmarked for future expenses, such as maintenance and repairs on equipment used to operate the RBSA, replacing items to keep the RBSA running, etc., but cannot be earmarked for other expenses outside the RBSA.
Sensitive Expenses
Any revenue generated by an RBSA is considered university funding. All expenses made using university funds must comply with the Tests of Propriety outlined in听. The Office of the University Controller (OUC) has a听 and tool that can be used to determine if your expenses are considered sensitive expenses.
If you cannot answer yes to the eight questions in the Test of Propriety, then the transaction is not an appropriate use of university funds.
When making purchases, it is important to use your best judgment and understand the intended use of the goods and services. Think about whether an outsider, such as the general public or an auditor, would consider the expenditure a reasonable expense for university business and an appropriate use of university funds.
- 鈥淲ould a university outsider, such as your dentist, a teacher at the local elementary school, the clerk at your grocery store, or your neighbor, consider the expenditure to be a reasonable and necessary expense of public funds?
- 鈥淲ould you want others 鈥 such as newspapers, radio, television, or other media outlets 鈥 knowing and reporting about what you have decided?鈥
Best Practice:
If you鈥檙e making purchases through your PCard or in 麻豆免费版下载Marketplace, it is best to document the justification for your expenses in the following way to justify the expense:
- What are you purchasing?
- Why is the purchase needed?
- How does the purchase benefit the University of Colorado?
Justifying the expense does not mean it exonerates it from being an inappropriate expense; it only provides reviewers and auditors with insight into the justification for the expense.
Campus Pooled Investment Earnings/Charges (PIE) Interest Expense
Pooled Investment Earnings/Charges (PIE) is a fancy way of saying interest. Similar to overdrawing a bank account or carrying a balance on a credit card, borrowing money incurs a cost. SpeedTypes with a negative cash balance are essentially 鈥渂orrowing money鈥 and are charged interest accordingly.
For more details about campus PIE, visit听CCOs website.
FAQ
My equipment has a longer useful life than what the university has established. 麻豆免费版下载says the equipment has a useful life of 7 years (84 months) and is depreciated annually at $5800 ($483.33/month), The manufacturer says the equipment has a useful life of 15 years (180 months) and should be depreciated annually at $2600 ($216.67/month). Can I use the manufacture depreciation guidelines?
No.听, depreciation on assets is calculated using the straight-line method ((asset cost - salvage value) / Useful Life) and is calculated in PeopleSoft. Each type of equipment is assigned an estimated useful life based on historical experience at CU. If no history exists, industry standards may be used, but please consult with听property@colorado.edu to confirm the appropriate useful life.
If an addition to the equipment is an economic enhancement and the useful life of the equipment is extended, depreciation is recalculated for the total cost of the item based on the new life.
The depreciation amount we are inputting is too high and is affecting the price I want to charge. Can I change the amount I want to depreciate?
No. If depreciation expense is included on the RBSA it must remain consistent. You should keep the depreciation amount that was calculated.
Why are interest charges on my RBSA SpeedType a thing?
The spending authority on a Fund 28/29 is cash-based, meaning the cash you have available is what you can spend. This is similar to other Fund 2X and 80 SpeedTypes. Overspending on an RBSA SpeedType is like borrowing money. Since it is cash-based, that money has to come from somewhere, and borrowing money incurs a cost.
PIE charges were developed due to a 1982 State Auditor recommendation.
How is PIE charged?
Quarterly interest is charged based on the daily average cash balance. Following each month end close, the average daily balances are calculated and stored in the PeopleSoft Finance System. For more details about campus PIE, visit听CCOs website.
What is the interest rate for PIE?
The interest rate for PIE is subject to change. As of 7/1/2025, the interest rate for PIE is currently set at 7.5% annually or 1.875% quarterly.
Why do I not see interest charged on my Fund 10 or 11, but on my Fund 28/29 RBSA?
Fund 1x and Fund 2x are two different spending authorities. A Fund 1x is budget-based (not cash-based), and its spending authority is based on the budget available from the general fund. A Fund 2x is cash-based, and its spending authority is based on its cash available.
Can I transfer cash from my Fund 28 to a Fund 29 or 78?
The only allowable cash transfers out of a fund 28 (or a fund 29 that charges federal customers) are to move any profits from non-federal external customers and a depreciation transfer. Any other cash balance must remain in the fund 28 (or federal charging fund 29). You are allowed to have excess cash in your fund 28/29 that is equal to 60 days of operating expenses. If you have anything in excess of this, you likely need to consider lowering your rates.
