At March 31, 2016, we did not hold any marketable securities. The municipal bonds all matured and the proceeds were transferred to our operating cash accounts. There were no material realized or unrealized gains or losses for the three or nine months ended March 31, 2016 and March 31, 2015. See also Note 12, “Fair Value Measurements".
