The following is a listing of the Company’s assets required to be measured at fair value on a recurring basis and where they are classified within the fair value hierarchy as of April 30, 2019 and July 31, 2018: April 30, 2019 Level 1 Level 2 Level 3 Total Available-for-sale securities: (unaudited, in thousands) Hedge Funds $ — $ — $ 4,632 $ 4,632 Total $ — $ — $ 4,632 $ 4,632 July 31, 2018 Level 1 Level 2 Level 3 Total Available-for-sale securities: (unaudited, in thousands) Marketable Securities $ 10,755 $ 13,946 $ — $ 24,701 Hedge Funds — — 4,218 4,218 Rafael Pharmaceuticals convertible promissory notes — — 7,900 7,900 Total $ 10,755 $ 13,946 $ 12,118 $ 36,819 At April 30, 2019 and July 31, 2018, the Company did not have any liabilities measured at fair value on a recurring basis.
