Accrued Interest

“Accrued interest is the accumulated interest that has been recognized and recorded but has not been paid as of a specific date… The total accrued interest should be recognized and recorded in the income statement even before the payment is received. The amount of interest that has been recognized as an expense by the borrower but has not yet been paid to the lender is known as accrued interest payable, which is recorded in the income statement as an expense… The accrual accounting concept requires that transactions should be recognized when they occur even if the payment has not been made. It ensures that the accumulated accrued interest is recognized and recorded in the right period when it occurs rather than when it is paid. It is contrary to the cash accounting concept, which requires that revenue and expense transactions be recorded when cash changes hands.” – CFI

Clearing system

“A set of rules and procedures whereby financial institutions present and exchange data and/or documents relating to transfers of funds or securities to other financial institutions at a single location (e.g a clearing house).
