Final answer:
General ledger updates for periodic adjusting entries are typically fed to the GL/BR process by one of the AIS feeder systems, as adjusting entries are part of the AIS, and not directly handled by high-level executives like the controller, treasurer, or CEO.
Step-by-step explanation:
Typically, general ledger updates for periodic adjusting entries would be fed to the GL/BR process by D) One of the AIS feeder systems. Adjusting entries are part of the accounting cycle and are used to record changes that have occurred but are not yet documented as transactions. This function is commonly automated within an Accounting Information System (AIS), which consists of various subsystems or feeder systems.Feeder systems are responsible for collecting data from different functional areas of business like sales, purchases, cash receipts, etc., and then processing this data to update the general ledger. They can be viewed as the intermediaries between a company's business activities and its financial records. The controller, treasurer, and CEO usually oversee or interpret financial data rather than being directly involved in the minutiae of data entry.
