What is the source of the Balance total line within Cash Management's 5-Day Forecast?

Summary:

Could you provide more detail on what is driving the 'Balance' total highlighted in the screenshot attached? I understand that the forecast takes into account the likely cash inflows and outflows from transactions in Payables, Receivables, Payroll, and Cash Management Amounts are reported per Legal Entity and Reporting Currency (Defined at Specify Cash Positioning and Forecasting Options); however, I'm curious how I can confirm the different sources of the 'Balance.'
