Which of the following is NOT a purpose for which normal income security proceeds can be used?

Normal income security proceeds are typically utilized for essential operating costs and obligations that are critical for maintaining a farm's viability and supporting the farmer's household. Using these funds for family living expenses helps ensure that the basic needs of the family are met, which is important for the overall stability of the household. Similarly, farm operating expenses are crucial for maintaining production and ensuring that the farm can continue to generate income.

Bank loan repayment is also a valid use of these proceeds, as it helps maintain the farmer's creditworthiness and keeps the farm financially stable by meeting existing obligations.

However, personal investments fall outside the typical scope of normal income security proceeds. These funds are intended for immediate, necessary expenses and obligations associated with running the farm and supporting the farmer's family, rather than for investing in personal ventures, which could potentially divert resources away from the farm's operational needs. Thus, personal investments do not align with the intended use of normal income security proceeds.
