Ann: AR9 to Present at Henslow Defence and Security Conference, page-330

I'd have to say your last line is a very valid point.
We don't get business updates like we used to get because there is the excuse of convenience - it's Defence. After 12 months the "Trust us we know what we're doing" mantra just isn't palatable anymore. They really do need to communicate with shareholders. While the financials in the last quarter are better than they have been in the past it does not alleviate the need to inform shareholders(who are essentially the owners of the Company) on business progress inlcuding POC's.
