Forecasting interest expense !

Greetings,

I'm in the process of valuing the equity of a company and I would appreciate if anyone with Bloomberg access (or any other credited source) would help me with the following:

1. Nominal GDP growth, real GDP growth & Inflation forecast for Bahrain between 2017-2021.

2. 6 month LIBOR forecast for 2016-2021 as I have to forecast the interest expense for the following loan:
   Principal= USD 1.5 billion
   Interest rate= LIBOR+3.25%, semiannual payments
   tenor=7years, including 3years grace period on principal payment of 8 semiannual installments for principal starting from 2019

PS. Do we have to de-annualize a 6months LIBOR when calculating semiannual interest payments??
