Trending @Infosys; Still waiting for rating.

I have been in a project for 9 months and before it was showing frozen in rating.Now it has been moved to rating with appraiser. And today it's 5th of Jan and still it's same. A person from my project and working with me got rating but for me there is no update. I spoke to manager he said for us it has not been updated. So I just wanted to know that is there any deadline for rating to be provided.
