Subscription of NIS 2012, will it extend the days left or exactly end for 1 years

I'm new to NIS 2012, but love it when tried for a while.

 

I'm using the NIS trial - 60 days version .

I bought the retail (box) versioin with product code in my hand.

 

I wonder , now i have 35 days left for trial use.

 

If I "subscribe with the prodcut code from the box" , how many day left I will get 

 

1) 35 + 365 days  or

2) 365 dasy 

 

Thanks in advance,

Lee
