I, unfortunately, provided all of the information from line 5 of the K-1. So, I can't say for certain what is meant or how it was calculated. Based on how things are referenced in other entries on this K-1 and other K-1s from the same source, I believe it is referring to margin interest. Note that there are amounts reported for investment interest expense (line 13, code H) and deductions, portfolio income (line 13, code AE). Neither of these amounts have additional detail that would reconcile to the amount reference in my original question for line 5.
