Contemporaneously with the offering, each outstanding share of preferred stock was automatically converted into two million shares of common stock. (b) Preferred Stock The Company is authorized to issue 20,000,000 shares of preferred stock. The Board of Directors is authorized to divide these shares into classes or series, and to fix and determine the relative rights, preferences, qualifications and limitations of the shares of any class or series so established. At December 31, 2019 and 2018, there was no preferred stock outstanding.

In conjunction with these agreements, the Company issued warrants to purchase up to 3,958 shares of common stock at $9.00 per share within 10 years of issuance. All of these warrants expired during 2017. In connection with the amendment to the debt agreements in 2009, the Company issued warrants to purchase up to 7,500 shares of common stock at $17.00 per share that expired in July 2019.

(f) Cumberland Emerging Technologies In April 2019, Cumberland Emerging Technologies ("CET"), our majority-owned subsidiary, entered into an agreement with WinHealth whereby WinHealth made a $1 million investment through the purchase of shares of CET stock. As part of the agreement, WinHealth obtained a Board position at CET and the first opportunity to license CET products for the Chinese market. In connection with WinHealth’s investment in CET, the Company also made an additional $1 million investment in CET. Cumberland purchased additional CET shares through contribution of $0.3 million in cash and a conversion of $0.7 million in intercompany loans payable. Upon completion of the additional investment by WinHealth and Cumberland, Gloria Pharmaceuticals agreed to return its shares in CET in exchange for consideration of $0.8 million. After the additional investment, the Company’s ownership in CET is 85%. As CET is a consolidated subsidiary, the Company reports the operating results of CET and allocates the noncontrolling interests to the non-majority partners. (g) Cumberland Foundation In December 2017, the Company formed the Cumberland Pharma Foundation (the "Foundation") to serve as a vehicle to facilitate the ongoing philanthropic endeavors of Cumberland Pharmaceuticals Inc. The Foundation was formed as a nonprofit corporation designed to qualify as a tax-exempt organization pursuant to Section 501(a) of the Internal Revenue Code. The Foundation’s Board of Directors is comprised of Cumberland Pharmaceuticals executives who are responsible for overseeing the Foundation’s ongoing activities including charitable contributions. In 2018, Cumberland provided a grant of 50,000 shares of the Company's common stock to the Foundation. The shares will address the ongoing financial needs of the organization, with most of the shares expected to be held for the opportunity to realize long term appreciation to support the Foundation’s future. The Foundation maintains separate financial statements and its ongoing operations will not impact the financial statements of Cumberland Pharmaceuticals. Initial annual grants by the Foundation have been and are expected to remain consistent with the historic level of contributions made by Cumberland Pharmaceuticals. During 2019, Cumberland Pharmaceuticals committed approximately $50,000 in cash contributions to be paid to the Foundation during 2020. (h) Nordic Group B.V.
