Subsequent Events [Abstract]
Subsequent Events	Subsequent Events In November 2017, concurrent with the closing of Oragenics' preferred stock financing, the Company exchanged its Oragenics' Promissory Note and receivables due from Oragenics, as well as accrued interest, totaling $3,376 for Oragenics Series C preferred stock ("Series C Preferred Stock"). The Series C Preferred Stock is non-voting and non-convertible and is redeemable in whole or part at any time by Oragenics in cash. The Series C Preferred Stock accrues an annual 12% dividend payable in additional Series C Preferred Stock through May 10, 2019, and after such date, the annual dividend increases to 20%. Additionally, the Company and Oragenics amended certain future payment terms under its ECCs. In October 2017, the Company entered into a Preferred Stock Equity Facility ("Preferred Stock Facility") with an affiliate of Third Security ("Third Security Affiliate"). Under the Preferred Stock Facility, the Company may, from time to time at its sole and exclusive option, issue and sell to the Third Security Affiliate, up to $100,000 of newly issued Series A Redeemable Preferred Stock ("Series A Preferred Stock"). Any issued Series A Preferred Stock is non-voting, accrues dividends of 8% per annum and, subject to limited exceptions, is senior to Intrexon's common stock with respect to the rights to the payment of dividends and on parity with the common stock with respect to the distribution of assets in the event of any liquidation, dissolution or winding up or change of control of Intrexon. Any issued Series A Preferred Stock is convertible into common stock only following receipt of shareholder approval by the Company, including a majority of the shares voted by those shareholders unaffiliated with Mr. Kirk (the "Shareholder Approval"), subject to any necessary regulatory approvals. Following receipt of the Shareholder Approval and receipt of any necessary regulatory approvals, any issued Series A Preferred Stock is convertible into Intrexon common stock based on a conversion price using the 20-day volume-weighted average market price as of market closing on the fifth business day prior to the mailing of the proxy statement soliciting the Shareholder Approval, subject to adjustment for certain stock splits and similar events. The Company has agreed to take all reasonable steps necessary to seek Shareholder Approval on or before the date of its annual meeting of shareholders in 2019. Any issued Series A Preferred Stock is redeemable at the election of the Company at any time, or at the election of the Third Security Affiliate after December 31, 2020. The Preferred Stock Facility will expire on the earliest to occur of: (i) the date on which the Third Security Affiliate has purchased shares of Series A Preferred Stock in the aggregate amount of $100,000, (ii) April 30, 2019, (iii) the date of the Shareholder Approval, and (iv) the mutual agreement of the parties. Also, in November 2017, the Company filed with the State Corporation Commission of the Commonwealth of Virginia (the "SCC") Articles of Amendment to the Company's Amended and Restated Articles of Incorporation (the "Amendment"), which amended Article III thereof to set the designations of the Series A Preferred Stock (described above) to be issued pursuant to the Preferred Stock Facility. The Amendment became effective upon the issuance by the SCC in November 2017 of a certificate of amendment.
