Which source of cash is the best indicator of a firm's viability as an ongoing concern?

Cash from production activities can be misleading as it may not encompass all operational cash flows. While production is a vital part of the business, it does not fully represent the cash generated from sales, collections, or overall operational efficiency. Therefore, it lacks the comprehensive view needed to assess ongoing viability effectively.

Cash from investing activities pertains to cash flows related to the purchase and sale of assets, such as property or equipment. While important for growth and expansion, it does not reflect the day-to-day operational performance of the business. Heavy investments may not indicate viability if the core operations are not generating adequate cash flow.

Cash from financing activities involves cash flows from borrowing or repaying debt and issuing or repurchasing stock. This source can provide temporary liquidity but does not indicate whether the underlying operations are profitable or sustainable. Reliance on financing can signal potential issues regarding a firm's ongoing viability.
