We used $1.6 million of cash for investing activities during the six months ended June 30, 2013, compared to $0.4 million of cash used for the six months ended June 30, 2012. Cash used for investing activities for the six months ended June 30, 2013 compared to the same period in the prior year increased $1.2 million, primarily due to $1.6 million in purchases of machinery and equipment to expand the manufacturing lines in preparation for a future approval of AFREZZA.
