What value GILD received in KITE purchase?

I see few sell side model updates for GILD for Kite Pharma purchase. The revenue predictions are running $1.5 to $5.5 but after 3 years, peaking around 2022, and the range based on the assumption of various % of the success of the pipeline.

So I am trying to understand what is the upside for Gilead in this purchase.

Thanks in advance.
