AWS / 13-month

I am currently working for this company since 15 August 2012.

I would like to find out if i am entitled to PRO-Rated 13mths?

In my Letter of Offer, it was stated

So am i entitled to PRO-RATED 13mths??

13-month or AWS is based on the individual company policy and it is governed under the MOM. To clarify on your enquiry, you shall seek your HR for clarification.
