The second part of a cash flow statement shows the cash flow from all investing activities, which generally include purchases or sales of long-term assets, such as property, plant and equipment, as well as investment securities. If a company buys a piece of machinery, the cash flow statement would reflect this activity as a cash outflow from investing activities because it used cash. If the company decided to sell off some investments from an investment portfolio, the proceeds from the sales would show up as a cash inflow from investing activities because it provided cash.
