Liquidity and Capital Resources
Liquidity and Capital Resources	2. Liquidity and Capital Resources As of June 30, 2019, the Company had approximately $21.4 million of cash and cash equivalents, $13.8 million of investments available-for-sale, working capital of $33.4 million and an accumulated deficit of $291.4 million. Net cash used in operating activities for the six months ended June 30, 2019 was approximately $15.8 million. On June 20, 2019, the Company closed a public offering of 5,833,334 shares of common stock at a price of $3.00 per share. The aggregate proceeds from this public offering (net of the underwriters’ commissions and offering expenses) were approximately $16.1 million. On July 9, 2019, the underwriters of the public offering partially exercised their over-allotment option and purchased an additional 425,800 shares of common stock at a price of $3.00 per share, which closed on July 11, 2019. The aggregate proceeds from the exercise of the over-allotment option (net of the underwriters’ discount and offering expenses) were approximately $1.2 million. On March 22, 2019, the Company entered into a sales agreement with Cantor Fitzgerald & Co. (the “Agent”), pursuant to which the Company may offer and sell from time to time shares of the Company’s common stock, no par value, through the Agent up to $40,000,000. We are not required to sell any shares at any time during the term of the facility. Our ability to sell common stock under the facility may be limited by several factors including, among other things, the trading volume of our common stock and certain black-out periods that we may impose upon the facility, among other things. Based on the capital raised from the June 20, 2019 offering and proceeds from the partial exercise of the over-allotment option on July 11, 2019, management believes the Company currently has sufficient funds to meet its operating requirements for at least the next twelve months from the date of the filing of this report. The Company will require additional capital to sustain its operations and make the investments it needs to execute upon its longer-term business plan, including the launch of Dialysate Triferic and I.V. Triferic. If the Company is unable to generate sufficient revenue from its existing long-term business plan, the Company will need to obtain additional equity or debt financing. If the Company attempts to obtain additional debt or equity financing, the Company cannot assume that such financing will be available on favorable terms, if at all.
