Fidelity insurance requires employer satisfaction of employee dishonesty before notice, and strict notice periods can bar recovery. Fidelity insurance indemnifies employers for pecuniary loss caused by employee dishonesty, distinct from contingency guarantees. The duty to notify insurers does not arise from mere suspicion but only after the employer is satisfied of the employee's dishonesty; prescribed notice periods from the date of loss can bar recovery if expiry occurs before employer satisfaction.
