CFI - A lot of times it is difficult to calculate this yourself. However, if this does show up on the test then it won't be too complicated. To calculate net purchases of PP&E, look at the change in gross PP&E year-over-year. If it decreased then they sold PP&E and thus have a cash inflow. For an increase, the opposite is true. You can do the same with marketable securities or long-term investments. If the company completed any acquisitions during the year then you wouldn't be able to calculate CFI yourself. You would need the company to break out PP&E purchases from the assets purchased in the acquisition. Any investments in joint ventures would also belong to CFI but I won't go into calculating the cash flow because I don't think you need to know if for LI.
CFF- Look at the difference in total interest-bearing debt year-over-year. By total debt I mean long-term debt, current maturities of long-term debt as well as any short-term notes payable. Subordinated debt would also be included. If debt increased then the company obviously issued debt, which is a cash inflow. If debt decreased then the reverse is true, the company retired some debt, which is a cash outflow. For cash flows from stock repurchases or issuances, look at the common stock account as well as paid in capital. If the number of shares issued and outstanding changes then the company either retired or issued shares. You will need to add up both the par value of the common stock and the paid in capital amount and take the difference year-over-year. Decreases are a cash outflow and increases are a cash inflow. NOTE: Sometimes companies will charge stock repurchases to retained earnings. I'm pretty sure CFAI wouldn't throw something like this at you on the test so I wouldn't worry about that. To calculate the dividend payment look at beginning retained earnings, net income and ending retained earnings. If there are no dividend payments then Ending RE=Beg RE + NI. If there are dividend payments then Ending RE = Beg RE + NI - Dividends. Alternatively, you can calculate dividend payments as Dividends = (Beg RE + Net Income) - Ending RE.
