What are four reasons why a depositors records and a banks records may differ?

Depositors' records and bank records may differ due to timing discrepancies, such as outstanding checks or deposits in transit that haven't been processed yet. Errors in recording transactions or data entry mistakes can also lead to inconsistencies. Additionally, fees or interest adjustments applied by the bank may not be reflected in the depositor's records. Lastly, unauthorized transactions or fraud can create discrepancies that need to be addressed.
