Change in Fair Value of Common Stock Warrant Liability. Change in fair value of common stock warrant liability for the nine months ended September 30, 2022 was zero compared to income of $0.6 million for the nine months ended September 30, 2021. The warrants were issued in November 2016 and May 2017 and the change in the liability fair value was due to a change in our stock price, volatility, and a shorter remaining term.
Income Tax Benefit. Income tax benefit was $2.4 million for the nine months ended September 30, 2022, compared to $1.8 million for the nine months ended September 30, 2021, an increase of $0.6 million, or 34%. In April 2022, we sold $25.1 million of state NOLs and $0.2 million of R&D tax credits under the State of New Jersey's Technology Business Tax Certificate Transfer Program for net proceeds of $2.2 million. In June 2021, we sold $16.4 million of state NOLs and $0.3 million of R&D tax credits under the State of New Jersey's Technology Business Tax Certificate Transfer Program for net proceeds of $1.7 million. The proceeds from such sales are recorded as income tax benefit when sales occur and proceeds are received.
Liquidity and Capital Resources
In the course of our development activities, we have sustained operating losses and expect such losses to continue over the next several years. We expect to continue to incur significant expenses and operating losses for the foreseeable future as we continue to develop, conduct clinical trials and seek regulatory approval for our product candidates. Our primary uses of capital are, and we expect will continue to be, compensation and related expenses, third-party clinical research and development services, contract manufacturing services, laboratory and related supplies, clinical costs, legal and other regulatory expenses and general overhead costs.
If we obtain regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses. We do not have a sales, marketing, manufacture or distribution infrastructure for a pharmaceutical product. To develop a commercial infrastructure, we will have to invest financial and management resources, some of which would have to be deployed prior to having any certainty of marketing approval.
We had unrestricted cash and cash equivalents of $11.3 million as of September 30, 2022. Our existing cash and cash equivalents as of September 30, 2022 will be used primarily to fund the Phase 3 trial of INOpulse for fILD.
The State of New Jersey’s Technology Business Tax Certificate Transfer Program enables qualified, unprofitable New Jersey based technology or biotechnology companies to sell a percentage of NOL and research and development (R&D) tax credits to unrelated profitable corporations, subject to meeting certain eligibility criteria. Based on consideration of various factors, including application processing time and past trend of benefits made available under the program, we believe that it is probable that our plans to sell our NOLs can be effectively implemented to address our short term financial needs. During April 2022, we completed the sale of $25.1 million of state NOLs and $0.2 million of R&D credits under the State of New Jersey’s Technology Business Tax Certificate Transfer Program for net proceeds of $2.2 million. We sold $16.4 million of state NOLs and $0.3 million of R&D tax credits under the State of New Jersey’s Technology Business Tax Certificate Transfer Program in June 2021 for net proceeds of $1.7 million. We plan to sell additional NOLs and R&D credits under the same program in the future subject to program availability
