Talked about GM, another thing which is very critical for the sustainable future success of any company and which we're very proud to mention that, we are very technology innovation driven company. I don’t know any company close to what we are doing. In our pipeline, we added some 600 patents and patents filing during fiscal 2012.
In last five years, we have added more patents than an entire company's history.

Good thing is we’re growing in all areas and we are market leader in all three divisions, Infotainment, Lifestyle, that is car audio and home and multimedia, and in our professional audio business where we are clear market leader and generate double-digit operating margin year-over-year.This is again, we are very happy that we have now 11 consecutive quarters of top line growth of 18% CAGR and bottom line EBITDA has grown 245% during 11 quarters.

We took lot of cost out and we invested heavily in technology, and we invested heavily in organic growth that is our BRIC country footprint. we are big player in Hungary, big player in Mexico, big player in China, and big player in Brazil and India now.
