b) Independent Internal Verification
c) Physical Control
Explanation:
I'll list the internal control principle in bold letters and then explain them a little.
(a) Company checks are prenumbered. DOCUMENTATION PROCEDURES.
These are meant to provide a paper trail to identify the events that occur in a company and pre numbering check ensures that the number is always known.
(b) The bank statement is reconciled monthly by an internal auditor. INDEPENDENT INTERNAL VERIFICATION.
Here the company runs its own checks and balances to ensure that they are in good shape.
(c) Blank checks are stored in a safe in the treasurer’s office. PHYSICAL CONTROL.
This refers to the use of physical devices to keep documents and assets safe and can include safes, vaults and safety deposit boxes.
