In connection with this acquisition, we preliminarily recorded $151.5 million of marketed product assets, with $55.4 million of other net assets. The final determination may result in asset and liability fair values that differ from the preliminary estimates, but it is not expected that these differences will be material to our consolidated financial statements.

We obtained a portfolio of more than 50 animal health products. In connection with this acquisition, we recorded $234.4 million of marketed product assets and $29.6 million of acquired in-process research and development (IPR&D) assets, with $43.8 million of other net assets.
