Fidelity Brokerage lists March 7th as date for 10k

Fidelity Brokerage lists March 7th as date for 10k release; yet we anticipate middle to end of march (90days past fiscal year to to file). I called brokerage specialist to inquire as to what information they base publication of these tentative days for some OTC stocks on. They said that is based on three things 1) previous timely SEC filings 2) being current 3) Info from company. When I asked specifically about ECIG they put me on hold for 10 min and then said its 1) and 2) but they have no record as to whether the company gave this date. When I asked about which date Fidelity posted this date they said they do not see that in their files (similarly, I did not get reliable info on why they changed the 10k date last week for ECIG from the 9th to the 7th). In other words (and it would not surprise me if TD Ameritrade has no info either on why they, too, list earnings release as March 7th) either these days are "made up" or companies can post anticipated dates somewhere (with the SEC; or similar) which some non-disclosed department in bigger brokerage firms has access to.
Weird, but we will find out on March 7th and learn from it. Among ECIG longs the consensus is that ECIG will file in the last week of March.
