Acquisition of Biohaven

Not allowing me to type below ..

QUESTION Regarding Pfizers acquisition of Biohaven, what was the value of the consideration? Your answer should be in millions of dollars. It should be an integer and you should omit the dollar sign.

On October 3, 2022, we acquired Biohaven, the maker of rimegepant, an innovative therapy approved for acute treatment of migraines. Under the terms of the agreement, we acquired all outstanding common shares of Biohaven not already owned by us for $148.50 per share. On the date of the acquisition we transferred cash of $11,500 million to the shareholders of Biohaven.

This acquisition follows on the November 2021 collaboration agreement in which we acquired 2.6 percent of Biohavens common stock. On October 3, 2022, this 2.6 percent equity interest had a fair (carrying) value of $200 ($150) million.

Per the acquisition agreement, certain former shareholders of Biohaven transferred their shares in exchange for the right to receive tiered royalties from Pfizer on any annual net sales of rimegepant in the U.S. in excess of $5.25 billion. This contingent consideration was determined to have a fair value as of October 3, 2022 of $100 million.

In connection with this business combination, on October 3, 2022, we recorded the following identifiable assets and liabilities:

Identifiable intangible assets	12,100
