In our condensed consolidated balance sheets, as of September 30, 2018 and June 30, 2018, money market balances were included in cash and cash equivalents and as of June 30, 2018, auction rate securities, or ARS investments, were included in non-current other assets. During the three months ended September 30, 2018 we converted our ARS investments to senior surplus notes, under an offering memorandum, which also included a receipt of a small amount of cash and warrants. We sold the senior surplus notes during the three months ended September 30, 2018, resulting in a gain of $2.8 million. There were no transfers in or out of our Level 1, 2, or 3 assets during the three months ended September 30, 2018 and 2017. The fair values of our accounts receivable and accounts payable approximate their carrying values because of the short-term nature of those instruments. Intangible assets, property and equipment, and goodwill are measured at fair value on a non-recurring basis if impairment is indicated.
