Series C Convertible Preferred Stock [Abstract]
SERIES C CONVERTIBLE PREFERRED STOCK	9. SERIES C CONVERTIBLE PREFERRED STOCK On October 10, 2000, Andrea issued and sold in a private placement $7,500,000 of Series C Redeemable Convertible Preferred Stock (the “Series C Preferred Stock”). Each of these shares of Series C Preferred Stock had a stated value of $10,000 plus a $1,671 increase in the stated value, which sum is convertible into Common Stock at a conversion price of $0.2551. On February 17, 2004, Andrea announced that it had entered into an Exchange and Termination Agreement and an Acknowledgment and Waiver Agreement, which eliminated the dividend of 5% per annum on the stated value. The additional amount of $1,671 represents the 5% per annum from October 10, 2000 through February 17, 2004. The shares of Series C Preferred Stock are subject to antidilution provisions, which are triggered in the event of certain stock splits, recapitalizations, or other dilutive transactions. In addition, issuances of common stock at a price below the conversion price then in effect (currently $0.2551), or the issuance of warrants, options, rights, or convertible securities which have an exercise price or conversion price less than that conversion price, other than for certain previously outstanding securities and certain “excluded securities” (as defined in the certificate of amendment), require the adjustment of the conversion price to that lower price at which shares of common stock have been issued or may be acquired. In the event that Andrea issues securities in the future which have a conversion price or exercise price which varies with the market price and the terms of such variable price are more favorable than the conversion price in the Series C Preferred Stock, the purchasers may elect to substitute the more favorable variable price when making conversions of the Series C Preferred Stock. In accordance with Sub Topic 815-40, Andrea evaluated the Series C Preferred Stock and concluded that it is not indexed to the Company’s stock because of the conversion price adjustment feature described above. Accordingly, under the provisions of ASC 815, “Derivatives and Hedging” (“ASC 815”), Andrea evaluated the Series C Preferred Stock embedded conversion feature. The Company has concluded that the embedded conversion feature would be classified in shareholders’ equity if it were a freestanding instrument, but as the Series C Preferred Stock is more akin to equity and as such it should not be bifurcated from the Series C instrument and accounted for separately. As of December 31, 2020, there were 11.469249 shares of Series C Preferred Stock outstanding, which were convertible into 524,736 shares of Common Stock and had remaining accrued dividends of $19,168.
