Which of the following is NOT a component of cash from operating activities?

Cash from operating activities primarily reflects the cash generated from a company's core business operations, which includes cash received from customers and cash paid to suppliers and employees. Each of the other options directly relates to operational cash flows.

Depreciation is added back to net earnings in the cash flow statement because it is a non-cash expense that reduces net income but does not affect cash flow. Therefore, it is a key component of operating cash flows.

Change in working capital involves fluctuations in current assets and current liabilities, impacting cash flow directly. This component measures how much cash is tied up or released in day-to-day operations, such as inventory and accounts receivable.

Net earnings represent the profit of a company after all expenses, including operating costs, have been deducted. It serves as the starting point for preparing the cash flow from operations section of the cash flow statement.

In contrast, acquisitions involve the purchase of other businesses or long-term assets and are classified under investing activities, not operating activities. This is why acquisitions is the option that does not belong within the context of cash from operating activities.
