Note: Changing your iterations setting, combined with the circularity of the debt plug and interest expense (later we’ll add the circularity of data tables), can lead to some confusing situations. It is easy to forget where you have your iterations set (more data tables lead to more circularity). When comparing your work to someone else’s, be sure that both of you have the same iterations setting and have hit (F9) the same number of times (be sure you either have no data tables or the same data tables). Your worksheet should now look like Exhibit 3.
