Statement of cash flows investing activities will look at cash flows related to investing activities. Investing activities will include cash flows from investments like stocks and bonds but also includes investments in long term assets like property plant and equipment. Cash outflows and cash inflows for property plant and equipment will be included in the investing activities section. Because equipment is often financed when purchased we often need to look at the detail of the transaction to complete the investing activities section.
