nwtf: I hold substantial positions in ET in 2 different tax-deferred retirement accounts, and I frequently get that form letter which states that my account and K-1 (Form 1065) may be examined for a possible need to issue me a 990-T, and I have heard of some very rare situations when a 990-T was issued within a tax-deferred IRA, but I always receive the follow-up letter saying that there was nothing in my situation which warranted issuance of the 990-T.
