In June 2008, a FASB approved guidance related to the determination of whether a freestanding equity-linked instrument should be classified as equity or debt under the provisions of FASB ASC Topic No. 815-40, Derivatives and Hedging – Contracts in an Entity’s Own Stock. The adoption of this requirement will affect accounting for convertible instruments and warrants with provisions that protect holders from declines in the stock price (“down-round” provisions). Warrants with such provisions are no longer recorded in equity and are reclassified as a liability.

Instruments with down-round protection are not considered indexed to a company’s own stock under ASC Topic 815, because neither the occurrence of a sale of common stock by the company at market nor the issuance of another equity-linked instrument with a lower strike price is an input to the fair value of a fixed-for-fixed option on equity shares.

In connection with the issuance of its 6% convertible debentures and related warrants, the Company has determined that the terms of the convertible warrants include down-round provisions under which the exercise price could be affected by future equity offerings. Accordingly, the warrants are accounted for as liabilities at the date of issuance and adjusted to fair value through earnings at each reporting date. On May 17, 2016, the Company entered into exchange agreements with holders of the Company's outstanding $504,168 convertible notes originally issued on December 28, 2015 pursuant to which the Notes were cancelled and the exchanging holders were issued an aggregate of 10,083,351 shares of newly designated Series G Convertible Preferred. Upon the conversion, additional paid in capital increased $649,662 from the decrease in convertible notes payable of $504,168, decrease in derivative liabilities of $146,502 and increase in Preferred Stock Series G of $1,008.

The convertible notes were accounted for as liabilities at the date of issuance and adjusted to fair value through earnings at each reporting date. The Company recorded amortization for the discount to the convertible notes of $602,515 at June 30, 2016. As of June 30, 2016 and December 31, 2015, the Company has unamortized discount balance of $0 and $602,515, respectively. The Company has recognized derivative liabilities of $0 and $614,036 at June 30, 2016 and December 31, 2015, respectively. The gain (loss) resulting from the decrease (increase) in fair value of this convertible instrument was $422,974 and ($64,035) for the six months ended June 30, 2016 and the year ended December 31, 2015, respectively.

The Company has recognized derivative liabilities for related warrants of $2,484 and $4,355 at June 30, 2016 and December 31, 2015, respectively. The gain resulting from the decrease in fair value of this convertible instrument was $1,872 and $580 for the six months ended June 30, 2016 and the year ended December 31, 2015, respectively. Weighted average term is 1.11 years.

The Company used the following assumptions for determining the fair value of the convertible instruments granted under the Black-Scholes option pricing model:
