Liquidity and Continued Operations	LIQUIDITY AND CONTINUED OPERATIONS On November 14, 2014, the Company entered into a securities purchase agreement (the "November 2014 Purchase Agreement") with one institutional and accredited investor (the "Investor"). Pursuant to the terms of the November 2014 Purchase Agreement, the Company sold to the Investor (i) $3,000,000 (3,000 shares) of Series D Convertible Preferred Stock (the "Series D Preferred Stock"), and (ii) $32,000,000 original principal amount of senior secured convertible notes (the "Notes"). On September 4, 2015, the Company entered into a Cancellation and Waiver Agreement (the “Cancellation Agreement”), between the Company and the Investor. The Cancellation Agreement was amended on October 8, 2015 and November 22, 2015. Pursuant to the Cancellation Agreement, the Company has agreed to retire all $21.2 million aggregate principal amount of its currently outstanding Notes. See Note 9 for further information related to the Cancellation Agreement and the subsequent Cancellation Agreement amendments. In February 2015, the Company completed the sale of 2,500 shares of Series D-1 preferred stock in a private placement for gross proceeds of $2.5 million. The transaction closed on February 25, 2015. See Note 9 for further information. On April 6, 2015, the Company entered into a securities purchase agreement with TFG Radiant for a private placement of a total of 1,000,000 shares of the Company’s common stock which resulted in gross proceeds of approximately $1 million to the Company. The transaction closed on April 17, 2015. On June 10, 2015, the Company entered into a securities purchase agreement with TFG Radiant for a private placement of a total of 1,000,000 shares of the Company’s common stock which resulted in gross proceeds of approximately $1 million to the Company. The transaction closed on July 10, 2015. On September 4, 2015, the Company entered into a note purchase agreement between the Company and two accredited investors (the “Lenders”). Pursuant to the new loan agreement, the Company issued to the Lenders $1.5 million original principal amount of secured subordinated convertible notes on September 4, 2015, and an additional $0.5 million original principal amount of secured subordinated convertible notes on September 28, 2015. See Note 10 for further information. On November 4, 2015, the Company entered into a securities purchase agreement with a Private Investor to issue 2,800 shares of Series E Preferred Stock to an investor in exchange for $2,800,000. See Note 11 for further information. On November 10, 2015, the Company and the Private Investor entered into a committed equity line purchase agreement (the "CEL"). Under the terms and subject to the conditions of the CEL purchase agreement, at its option the Company has the right to sell to the Private Investor, and the Private Investor is obligated to purchase from the Company, up to $32.2 million of the Company’s common stock, subject to certain limitations, from time to time, over the 36-month period commencing on December 18, 2015, the date that the registration statement was declared effective by the SEC. The remaining availability under the CEL as of December 31, 2015 is $30.2 million. Actual sales of shares of common stock to the Private Investor under the CEL purchase agreement will depend on a variety of factors to be determined by the Company from time to time, including, among others, our ability to register shares of common stock with the SEC, market conditions, the trading price of the common stock and determinations by the Company as to the appropriate sources of funding for the Company and its operations. As of January 27, 2016, the Company is not able to access the CEL because the Company does not have any registered shares available for use in connection with the CEL purchase agreement. The Company is in the process of registering an additional 48,000,000 shares for such purpose with the SEC. If such additional registration statement is declared effective by the SEC and such additional shares become available for use by the Company, the Company’s sales of shares pursuant to the CEL purchase agreement during 2016 would be limited to such 48,000,000 shares. The Company’s use of the CEL in 2017 and beyond would require, among other things, the Company to file additional registration statements in the future that cover additional shares and have such registration statements declared effective. The Company would also need to maintain the effectiveness of such additional registration statements. The Company has continued PV production at its manufacturing facility. The Company does not expect sales revenue and cash flows will be sufficient to support operations and cash requirements until it has fully implemented its new consumer products strategy. Changes in the level of expected operating losses, the timing of planned capital expenditures or other factors may negatively impact cash flows and reduce current cash and investments faster than anticipated. During 2015 the Company used $22.1 million in cash for operations, or an average of $5.5 million per quarter. During the fourth quarter of 2015 the Company used $4.6 million in cash for operations. The Company's primary significant long term obligation consists of a note payable of $5.8 million to a financial institution secured by a mortgage on its headquarters and manufacturing building in Thornton, Colorado. Total payments of $0.8 million, including principal and interest, will come due in 2016. Additionally, the Company owes $0.9 million as of December 31, 2015 related to a litigation settlement reached in April 2014, which is being paid in equal installments over 40 month which began April 2014. Additional projected product revenues are not anticipated to result in a positive cash flow position for the year 2016 overall. As such, cash liquidity sufficient for the year ending December 31, 2016 will require additional financing. Subsequent to year end, on January 19, 2016, the Company entered into a securities purchase agreement (the “Series F SPA”) with the Private Investor for the sale of $7,000,000 of the Company’s newly designated Series F 7% Convertible Preferred Stock (the “Series F Preferred Stock”). See Note 20 for further information. The Company continues to accelerate sales and marketing efforts related to its consumer products strategy through increased hiring and expansion of its sales channel. The Company has begun activities related to securing additional financing through strategic or financial investors, but there is no assurance the Company will be able to raise additional capital on acceptable terms or at all. If the Company's revenues do not increase rapidly, and/or additional financing is not obtained, the Company will be required to significantly curtail operations to reduce costs and/or sell assets. Such actions would likely have an adverse impact on the Company's future operations. As a result of the Company’s recurring losses from operations, and the need for additional financing to fund its operating and capital requirements, there is uncertainty regarding the Company’s ability to maintain liquidity sufficient to operate its business effectively, which raises substantial doubt as to the Company’s ability to continue as a going concern.
