Stockholders' Deficit, Option Plans, and Employee Benefit Plan [Abstract]
Stockholders' Deficit, Option Plans, and Employee Benefit Plan	Note 8. Stockholders' Deficit and Employee Benefit Plan General Our authorized capital stock consists of 250,000,000 shares of common stock, $0.001 par value per share, and 10,000,000 shares of preferred stock, $0.01 par value per share. Prior to our Second Amended and Restated Articles of Incorporation, which were effective November 12, 2020, the relative rights, preferences, and limitations of the Class A common stock and the Class B common stock were in all respects identical. The holders of the common stock had one vote for each share of common stock held. Our Second Amended and Restated Articles of Incorporation authorize our Board of Directors to classify or reclassify shares of our stock in one or more classes or series, to cause the issuance of additional shares of our stock, and to amend our charter without stockholder approval to increase or decrease the number of shares of stock that we have authority to issue. On November 12, 2020, we filed Articles of Amendment (the “Articles”) with the State Department of Assessments and Taxation of the State of Maryland, effective as of the same date (the “Effective Time”). The Articles amend the Company’s charter to effect a reverse stock split such that (1) every 1.259446 shares of Class A Common Stock that were issued and outstanding immediately prior to the Effective Time were changed into one issued and outstanding share of Class A Common Stock, and (2) every 1.259446 shares of Class B Common Stock that were issued and outstanding immediately prior to the Effective Time were changed into one issued and outstanding share of Class B Common Stock. Also on November 12, 2020, we filed the Second Articles of Amendment and Restatement (the “Second Amended Articles”) with the State Department of Assessments and Taxation of the State of Maryland, effective as of the same date (the “Effective Time”). The Second Amended Articles amend the Company’s charter to effect a conversion of each share of the Class B Common Stock that were issued and outstanding immediately prior to the Effective Time into one fully paid and nonassessable share of Class A Common Stock. From and after the Effective Time, certificates representing the Class B Common Stock now represent the number of shares of Class A Common Stock in which such Class B Common Stock was converted. Also at the Effective Time, the Class A Common Stock was renamed and redesignated as common stock, par value $0.001 per share, of the Corporation. As of December 31, 2020, there were 64,625,071 shares of common stock outstanding and no shares of preferred stock outstanding. Restricted Stock Grants Since June 2008, we have issued restricted stock to our executive officers, directors and employees. Such stock is subject to a vesting schedule as follows: 25% of the restricted stock vests immediately on the date of grant, thereafter, an additional 25% will vest annually on the anniversary of the date of grant subject to continued employment or services. In the event of death of the employee or a change in control, as defined by the Telos Corporation 2008 Omnibus Long-Term Incentive Plan, the 2013 Omnibus Long-Term Incentive Plan, or the 2016 Omnibus Long-Term Incentive Plan, all unvested shares shall automatically vest in full. In accordance with ASC 718, we recorded immaterial compensation expense for any of the issuances as the value of the common stock was nominal, based on the deduction of our outstanding debt, capital lease obligations, and preferred stock from an estimated enterprise value, which was estimated based on discounted cash flow analysis, comparable public company analysis, and comparable transaction analysis. Additionally, we determined that a significant change in the valuation estimate for common stock would not have a significant effect on the consolidated financial statements. In May 2017, we issued grants of 3,972,007 shares to our executive officers and employees. The shares vest according to the schedule set forth above. There were 3,948,199 shares outstanding at the beginning of 2018, and 43,649 shares were forfeited during 2018. There were no new grants in 2018. There were 3,904,550 shares outstanding at the beginning of 2019, and 11,904 shares were forfeited during 2019. There were no new grants in 2019. At the beginning of 2020 there were 3,892,646 shares outstanding and 47,616 were forfeited prior to May 2020, when the remaining 3,845,030 shares became fully vested. Upon vesting there were no remaining restrictions on these shares and they are able to be sold or disposed of, subject to any lock-up agreements subsequently entered into by certain holders of the shares in connection with the IPO of the Company’s common stock in November 2020. In May 2020, 79,361 shares were granted. As of December 31, 2020, there were 59,521 shares of restricted stock that remained subject to vesting. Telos Shared Savings Plan We sponsor a defined contribution employee savings plan (the “Plan”) under which substantially all full-time employees are eligible to participate. As of December 31, 2020, the Plan held 2,391,552 shares of Telos common stock. We match one-half of employee contributions to the Plan up to a maximum of 2% of such employee’s eligible annual base salary. Participant contributions vest immediately, and Company contributions vest at the rate of 20% each year, with full vesting occurring after completion of five years of service. Our total contributions to the Plan for 2020, 2019, and 2018 were $998,000, $861,000, and $721,000, respectively. Additionally, Telos ID sponsors a defined contribution savings plan (the “Telos ID Plan”) under which substantially all full-time employees are eligible to participate. Telos ID matches one-half of employee contributions to the Telos ID Plan up to a maximum of 2% of such employee’s eligible annual base salary. The total 2020, 2019, and 2018 Telos ID contributions to this plan were $179,000, $151,000, and $125,000, respectively.
