This post completes our exploration of the definition of “derivatives transactions” in Rule 18f-4, which is relevant to business development companies, closed-end funds and open-end funds other than a money market fund (“Funds”). Our object is to generate a fairly comprehensive list of what is, is not, and may be a “derivatives transaction” by using our touchstone of a “future payment obligation” in combination with the literal definition in the rule and points made in earlier posts.
