rate and 5.5%. The interest rate on the line of credit was 5.5% as of March 31, 2021. The line of credit is secured by the Company’s consolidated assets.
There were no outstanding borrowings under the line as of March 31, 2021 and June 30, 2020, respectively. As of March 31, 2021, there was approximately $1,888,000 of available credit.
Note 4. Lease Obligations
On December 30, 2016, the Company entered into a 48 month non-cancellable lease for its office facilities that will require monthly payments ranging from $10,350 to $11,475 through January 2021. In accounting for the lease, the Company adopted ASU 2016-02, Leases which requires a lessee to record a right-of-use asset and a corresponding lease liability at the inception of the lease initially measured at the present value of the lease payments. The Company classified the lease as an operating lease and determined that the value of the lease assets and liability at the inception of the lease was $463,000 using a discount rate of 3.75%. During the nine months ended March 31, 2021, the Company made payments of $79,326 towards the lease liability. As of March 31, 2021 and June 30, 2020, lease liability amounted to $0 and $79,326, respectively. ASU 2016-02 requires recognition in the statement of operations of a single lease cost, calculated so that the cost of the lease is allocated over the lease term, generally on a straight-line basis. Rent expense, including real estate taxes, for the nine months ended March 31, 2021 and 2020 was $35,065 and $97,275, respectively. The right of use asset at June 30, 2020 was $72,331. During the nine months ended March 31, 2021, the Company reflected amortization of right of use asset of $72,331 related to this lease, resulting in a net asset balance of $0 as of March 31, 2021.
On October 8, 2019, the Company entered into an agreement to sublease its office facilities from November 1, 2019 through January 31, 2021, the end of the lease term, for $8,094 per month with one month of abated rent. The Company recorded rent income of $56,658 during the nine months ended March 31, 2021. This amount is reflected as an offset to rent expense that is included in general and administrative expenses in the accompanying statements of operations.
Note 5. Stockholders’ Equity
Stock Options
In December 2007, we established the 2007 Equity Compensation Plan (the “2007 Plan”) and in November 2017 we established the 2017 Omnibus Incentive Plan (the “2017 Plan”), collectively (the “Plans”). The Plans were approved by our board of directors and stockholders. The purpose of the Plans is to grant stock and options to purchase our common stock, and other incentive awards, to our employees, directors and key consultants. On November 10, 2016, the maximum number of shares of common stock that may be issued pursuant to awards granted under the 2007 Plan increased from 5,000,000 to 7,000,000. On November 21, 2017, the Company’s stockholders approved the adoption of the 2017 Plan (previously adopted by our board of directors on September 14, 2017), which authorized a maximum of 1,874,513 shares of common stock that may be issued pursuant to awards granted under the 2017 Plan. On November 17, 2020, the Company's stockholders approved an increase in the maximum number of shares of common stock that may be issued pursuant to awards granted under the 2017 Omnibus Incentive Plan from 2,374,513 to 3,374,513. Upon adoption of the 2017 Plan we ceased granting incentive awards under the 2007 Plan and commenced granting incentive awards under the 2017 Plan. The shares of our common stock underlying cancelled and forfeited awards issued under the 2017 Plan may again become available for grant under the 2017 Plan. Cancelled and forfeited awards issued under the 2007 Plan that were cancelled or forfeited prior to November 21, 2017 became available for grant under the 2007 Plan. As of March 31, 2021, there were 1,129,483 shares available for grant under the 2017 Plan, and no shares were available for grant under the 2007 Plan. All incentive stock award grants prior to the adoption of the 2017 Plan on November 21, 2017 were made under the 2007 Plan, and all incentive stock award grants after the adoption of the 2017 Plan on November 21, 2017 were made under the 2017 Plan.
The majority of awards issued under the Plan vest immediately or over three years, with a one year cliff vesting period, and have a term of ten years. Stock-based compensation cost is measured at the grant date, based on the fair value of the awards that are ultimately expected to vest, and recognized on a straight-line basis over the requisite service period, which is generally the vesting period.
