Assuming the number of shares held by the POLIS Group remained the same, then the anser to your qerry about how many shares were issued by the company is;

8.5-7.2= 1.3% of the aggregate number of total shares were issued last year...

Putting it another way you could conclude that whatever the number of share were at the start of 2009 was increased by a number which made the percentage of total shares owned by POLIS drop by 1.3%...

As dischino would say, CAPISH?...Lol...Lol...
