In May 2013, Takeda recalled one specific batch of Rienso from the Swiss market. The batch was only distributed to and sold in Switzerland and the recall was limited to the specific batch and specifically in Switzerland. During the three months ended June 30, 2013, we expensed $0.5 million of inventory related to this batch of Rienso which we no longer believed was suitable for sale and which was the subject of the voluntary recall by Takeda in the Swiss market.

In connection with the Access License Agreement, we purchased the entire MuGard inventory held by Access, at cost. As of June 30, 2013, we recorded $0.2 million of MuGard inventory, which represented its full fair value in our condensed consolidated balance sheet.
