Purchase of Telos ID/Non-Controlling Interests [Abstract]
Purchase of Telos ID Non-controlling Interests	Purchase of Telos ID Non-controlling InterestsTelos ID was formed as a limited liability company under the Delaware Limited Liability Company Act in 2007. Prior to the IPO, the Company owned a 50% interest in Telos ID, with the remaining interest owned by Hoya ID Fund A, LLC ("Hoya") as the non-controlling interest. Distributions were made to the members only when and to the extent determined by Telos ID’s Board of Directors, in accordance with its Operating Agreement.On October 5, 2020, we entered into a Membership Interest Purchase Agreement between the Company and Hoya to purchase all of the Class B Units of Telos ID owned by Hoya (the “Telos ID Purchase”). Upon the closing of the Telos ID Purchase, Telos ID became our wholly owned subsidiary. On November 23, 2020, the Telos ID Purchase was consummated with the Company transferring $30.0 million in cash and issuing 7.3 million shares of our common stock at $20.39 per share (which totals approximately $148.4 million); the total consideration transferred to Hoya was $178.4 million. As part of the common stock issuance, the Company recognized a credit to additional paid-in capital (“APIC”) of $148.4 million. The Company further recognized a debit to APIC of $173.9 million as part of the elimination of Hoya’s non-controlling interest in Telos ID. The net impact to APIC associated with the acquisition of the additional 50% interest in Telos ID was a debit of $25.5 million. Hoya received the final distribution of $2.4 million in January 2021.
