Identify the internal control principle that was violated in each of the following separate situations.

Situations

a$.$ An employee was put in charge of handling cash. That employee later stole cash from the business. The company incurred

an uninsured loss of $$184,000.$

b$.$ There is $$500$ in cash missing from a cash register drawer. Three salesclerks shared the cash register drawer, so the

owner cannot determine who is at fault.

c$.$ An employee stole thousands of dollars worth of equipment over many years. It took years for the company to discover the

fraud because accounting records for equipment were rarely updated.
