Final answer:
Purchasing new insurance to cover an existing risk generally results in additional cash outflows and may not have a positive impact on cash flow, unlike other actions which can improve cash flow by reducing expenses or debts.
Step-by-step explanation:
Among the recommendations listed, the one that may not have a positive impact on cash flow is d. purchasing new insurance to cover an existing risk. This is because while raising insurance deductibles (a), reducing the amount of insurance coverage (b), and paying off existing debt with balance sheet assets (c) can contribute to immediate cash flow improvement by either reducing outgoing cash or eliminating interest payments, purchasing new insurance typically results in additional cash outflows due to premium payments, which can reduce cash flow.
