Stockholders' Equity Note [Abstract]  
Stockholders' Equity Stockholders’ Equity AGI maintains two stock-based incentive plans: the 2012 Equity Incentive Plan (the “2012 Plan”) and 2018 Equity Incentive Plan (the “2018 Plan”) that provides for the grant of shares in the form of incentive stock options, non-qualified stock options, restricted shares, stock appreciation rights and RSUs to employees, consultants, officers and directors.
On December 30, 2020, the Company held its Annual Meeting of Shareholders at which the shareholders voted to amend the 2018 Plan to increase the number of shares of common stock available for issuance under the 2018 Plan from 1,100,000 to 1,600,000 shares.

As of July 31, 2021 and April 30, 2021 there were 431,869 and 549,739 shares remaining available for future issuance under the 2012 and the 2018 Plans, respectively.

Restricted Stock
As of July 31, 2021 and 2020, there were 8,224 and 16,448 unvested shares of restricted common stock outstanding, respectively. Total unrecognized compensation expense related to the unvested shares as of July 31, 2021 was $17,545, and is expected to be recognized over a weighted-average period of approximately 0.42 years.

Restricted Stock Units
A summary of the Company’s RSU activity during the three months ended July 31, 2021 is presented below:
Restricted Stock Units Number of Shares Weighted Average Grant Price
Unvested balance outstanding, April 30, 2021 549,972  $ 6.58

Unvested balance outstanding, July 31, 2021 653,937  $ 6.07 
Of the 127,542 RSUs granted in the three months ended July 31, 2021, 125,000 RSUs correspond to the Chief Executive Officer grant. On July 21, 2021, as part of a new employment agreement, the Compensation Committee approved a 125,000 RSU grant to the Company's Chief Executive Officer under the Company's 2018 Equity Incentive Plan. The grant has a grant date fair value of $873,750 based on a closing stock price of $6.99 per share. As stipulated in the grant, vesting is subject to continued employment with the Company and will occur in full on the date the Company files with the SEC a quarterly or annual report on Forms 10-Q or 10-K, as applicable, which reflects the Company reported net income on a GAAP basis. The Company is amortizing the expense over one year through July 2022 (the filing date of the Form 10-K for Fiscal Year 2022). At each reporting period of Fiscal Year 2022, the Company will re-assess the likelihood of the performance condition to be met in the fourth quarter of 2022. If the RSUs do not vest within three years from the July 21, 2021 effective date, they will expire and automatically be forfeited. The amortization expense related to this grant for the three months ended July 31, 2021 was $72,813, which is included in general and administrative expense in the consolidated statements of operations. The remaining 2,542 RSUs were granted to employees and have a grant date fair value that ranges from $4.92 to $6.50 per share, or a total of $14,943, vesting annually over three years.
Of the 653,937 unvested RSUs outstanding at July 31, 2021, there are 195,000 RSUs remaining from the February 4, 2020 executive grant. These RSUs vest four years from the grant date, if each applicable executive is still employed by the Company on the vesting date and subject to accelerated vesting for all RSUs if the closing price of the Company’s common stock is at least $12 for 20 consecutive trading days, all of the unvested RSUs will vest immediately. On the grant date, the closing price of the Company's common stock on The Nasdaq Global Market was $9.49 per share. The amortization expense related to these transactions for the three months ended July 31, 2021 and 2020, was approximately $112,155 and $111,211, respectively, which is included in general and administrative expense in the consolidated statements of operations.
At July 31, 2021, total unrecognized compensation expense related to unvested RSUs is $3,972,803 and is expected to be recognized over a weighted-average period of approximately 1.49 years. The total unrecognized compensation expense related to the February 4, 2020 executive RSU grant, discussed above, is $1,121,555.
Warrants
The Company estimates the fair value of warrants utilizing the Black-Scholes pricing model, which is dependent upon several variables such as the expected term, expected volatility of the Company’s stock price over the expected term, expected risk-free interest rate over the expected term and expected dividend yield rate over the expected term. The Company believes this valuation methodology is appropriate for estimating the fair value of warrants issued to directors which are subject to ASC Topic 718 requirements. These amounts are estimates and thus may not be reflective of actual future results, nor amounts ultimately realized by recipients of these grants. The Company recognizes expense on a straight-line basis over the vesting period of each warrant issued.

On July 21, 2021, the Compensation Committee approved warrants to a former member of the Board of Directors for the purchase of 25,000 shares of the Company's common stock with an exercise price of $6.99 per share. The warrants have an exercise period of five years from the July 21, 2021 issuance date and vest annually over a three year period subject to continued service on the Company's Advisory Board on each applicable vesting date. The warrants will terminate automatically and immediately upon the expiration of the exercise period. The relative fair value of the warrants is $84,000 and is being amortized over the three year vesting period. The Company has recognized $2,333 of amortization expense in connection with the fair value of the warrants for the three months ending July 31, 2021, which is included in “general and administrative” expense in the consolidated statement of operations.
During the three months ended July 31, 2020, there was a warrant modification and acceleration charge of $25,966 related to the exercise of 192,049 warrants by the Leon and Toby Cooperman Family Foundation, which was included in “other income (expense), net” in the consolidated statement of operations.
Stock Option Grants to Employees and Directors
The Company estimates the fair value of share-based compensation utilizing the Black-Scholes option pricing model, which is dependent upon several variables such as the expected option term, expected volatility of the Company’s stock price over the expected term, expected risk-free interest rate over the expected option term and expected dividend yield rate over the expected option term. The Company believes this valuation methodology is appropriate for estimating the fair value of stock options granted to employees and directors which are subject to ASC Topic 718 requirements. These amounts are estimates and thus may not be reflective of actual future results, nor amounts ultimately realized by recipients of these grants. The Company recognizes compensation on a straight-line basis over the requisite service period for each award.

The Company utilizes the simplified method to estimate the expected life for stock options granted to employees. The simplified method was used as the Company does not have sufficient historical data regarding stock option exercises. The expected volatility is based on historical volatility. The risk-free interest rate is based on the U.S. Treasury yields with terms equivalent to the expected life of the related option at the time of the grant. Dividend yield is based on historical trends. While the Company believes these estimates are reasonable, the compensation expense recorded would increase if the expected life was increased, a higher expected volatility was used, or if the expected dividend yield increased.
