Hey! I'm studying Proprietary Funds right now. (Its not my favorite.)
Its the fund that provides services to other departments within the government, like janitorial services. The accounting is full accrual just like a regular business, except all the “customers” are other departments. So, you might have a Central Janitorial Service Fund that hires janitors, sends them to all the government buildings, and then sends bills out to each entity.
It shows up with the enterprise fund on the Proprietary Fund financial statements.
It gets combined with the governmental funds into the government-wide financial statements.
It shows up in the reconciliation from governmental funds up to the government-wide financials.
The general fund is a governmental fund. It uses modified accrual basis, like a cash checkbook.
You can get a ton of governmental MCQ's right on the exam just by knowing the three types of funds, the funds in each type, the accounting method (full accrual or modified accrual), and the purpose of each fund. It also helped me to know the Governmental Financial Statement Presentation format (MD&A, Government-wide FS, Fund FS, Required Supplementary Info, and also know what a CAFR is).
Sorry if that's more than you asked for 🙂
