Changes to DRC Mining Code

If my information is correct,it will be necessary for mining companies operating in the DRC,to cede a 15% interest in that company,to the government in order to keep the tenements in good standing.Any comments from my learned friends with regard to possible implications,to TIGER going forward?As per previous ANN's it was originally to be a 5% interest.Doe's this have an effect in diluting shareholder value?
