Risk sharing occurs when two or more parties agree to divide or collectively absorb the financial consequences of losses. Pooling money to cover malpractice exposures is a direct example because multiple participants contribute resources to a common fund from which qualifying losses can be paid.
The other choices illustrate different risk-management techniques. Purchasing an insurance policy is principally risk transfer because the insured transfers specified financial consequences of loss to an insurer in exchange for a premium. Installing a sprinkler system is risk reduction because the measure decreases the probability or severity of fire damage. Choosing not to purchase a car is an example of risk avoidance, since the individual avoids the activity or property that creates the particular exposure.
Risk sharing is closely related to the pooling principle underlying insurance, although the examination distinguishes sharing from formal contractual transfer to an insurer. Professional groups may create arrangements in which participants collectively fund malpractice exposures, thereby spreading losses across a larger pool rather than requiring a single participant to bear the entire financial burden.
Therefore, D most precisely demonstrates sharing of risk among multiple participants.
