i think your right there, plus he may not have to give another notification, till over the next whole %, ie 4%
"LONDON (AFX) - Pan Andean Resources PLC said Thomas and Philomena O'Gorman
hold 4 mln shares in the company, representing a stake of 3.36 pct."
"The Company's issued share capital comprises 119,227,733 ordinary shares of 1p
each. All of the ordinary shares have equal voting rights and none of the
shares are held in treasury. The total number of voting rights is, therefore,
119,227,733."
so, to get over 4%, and trigger an rns, he needs another
(119,227,733 *4/100) - 4,000,000 = 769,109 shares
of course, it was 27/9 that he had the 4 mil, so could well have picked more up since, and therefore be quite near the 4%
