CSL is one of the largest global biotech companies and has two main segments. CSL Behring either uses plasma-derived proteins or recombinants to treat conditions including immunodeficiencies, bleeding disorders and neurological indications. Seqirus is now the world's second largest influenza vaccination business and was acquired in fiscal 2015. CSL has a strong R&D track record, and the product portfolio and pipeline include nonplasma products as the firm continues to broaden its scope. Originally formed in Australia as a government-owned entity, CSL now earns roughly half its revenue in North America and a quarter in Europe.
