When Grifols SA, one of the world’s largest blood plasma products manufacturers, decided to buy Triangle-based rival Talecris, it came with a price.

A big one – $4 billion.

The financing is the biggest leveraged loan to be raised this year, according to data compiled by Bloomberg.

The Talecris-Grifols deal closed last June.
