General and administrative expenses increased by $0.8 million for the nine months ended June 30, 2022, as compared to the nine months ended June 30, 2021, primarily due to increases in professional fees, settlement costs, and wage expenses, partially offset by a decrease in stock-based compensation expense.

Change in Fair Value of Warrant Liabilities
Change in fair value of warrant liabilities reflects the changes in the fair value of outstanding warrants measured at fair value on a reoccurring basis, which is primarily driven by changes in our stock price. The fair value of warrant liabilities was $0 at June 30, 2022 and September 30, 2021, therefore, no change in fair value was recognized during the nine months ended June 30, 2022. During the nine months ended June 30, 2022, warrants measured at fair value expired unexercised. We recognized a gain of $0.9 million from the change in fair value of warrant liabilities for the nine months ended June 30, 2021.
Equity in Losses on Equity Method Investment
We account for our investment in DepYmed common shares using the equity method of accounting and record our proportionate share of DepYmed’s net income and losses. As of June 30, 2022 and September 30, 2021, the carrying value of our investment in DepYmed common shares was reduced to zero, therefore, during the nine months ended June 30, 2022, we recorded our share of equity losses to the extent of our investment in preferred shares of DepYmed. We will continue to monitor the operating results of DepYmed and will record equity in earnings when the equity in earnings exceeds our previously unrecognized losses. Equity in losses was $0.4 million for the nine months ended June 30, 2022, and $0.1 million for the nine months ended June 30, 2021.
