R. RESTRUCTURING

In connection with the CBR and Lumara Health acquisitions, we initiated restructuring programs in the third quarter of 2015 and the fourth quarter of 2014, respectively, which included severance benefits primarily related to certain former CBR and Lumara Health employees. As a result of these restructurings, we recorded charges of approximately $0.1 million and $0.7 million in the three and six months ended June 30, 2016, respectively as compared to $0.4 million and $1.0 million in the same periods in 2015 . We expect to pay substantially all of these restructuring costs by the end of 2016.

The following table outlines the components of our restructuring expenses which were included in current liabilities for the three and six months ended June 30, 2016 and 2015 (in thousands):
