We got a couple of replies to this question.
Stacey Ash at iFunds said: "Unless the fund has reporting status all gains will be treated as income by HMRC."
Charles Mackinnon at Thurleigh Investment Management said: "Remembering that we are not accountants or tax experts, my understanding is that if a security is showing a loss, it counts as a capital loss irrespective as to reporting status or not. The fact that the fund is “seeking” reporting status is irrelevant."
