SVB, and to maintain its and its subsidiaries’ primary operating and other deposit accounts with SVB. In compliance with the foregoing covenants the Company and its subsidiaries maintained with SVB substantially all of the dollar value of the Company’s and its subsidiaries’ accounts. At February 28, 2023, the Company held cash at SVB of $10,832,000, of which we estimate $9,738,000 was in excess of government insured limits.
On March 10, 2023, SVB was closed by the California Department of Financial Protection and Innovation, and the Federal Deposit Insurance Corporation (“FDIC”) was appointed as receiver and SVB was subsequently transferred into a new entity, Silicon Valley Bridge Bank, N.A. (“SVB Bridge Bank”). On March 12, 2023, the U.S. Treasury Department, the Federal Reserve and the FDIC jointly announced enabling actions that fully protect all SVB depositors’ insured and uninsured deposits, and that such depositors would have access to all of their funds starting March 13, 2023. On March 14, 2023, the Company was able to access its full deposits with SVB Bridge Bank. At June 30, 2023, the Company held cash at SVB Bridge Bank of $7,580,000, of which we estimate $6,443,000 was in excess of government insured limits.
There were no outstanding borrowings under the line as of June 30, 2023 and June 30, 2022, respectively. As of June 30, 2023, there was approximately $2,264,000 of available credit. On March 27, 2023, First Citizens BancShares, Inc entered into an agreement with the Federal Deposit Insurance Corporation (FDIC) to purchase all of the assets and liabilities of SVB. The Company has confirmed that the Loan and Security Agreement remains in effect post this transaction and that, in addition to having access to all of its deposits with SVB, it continues to have access to the revolving line of credit.
SVB Bridge Bank agreed that the Company can lower its cash balance threshold requirement associated with the SVB LSA, reducing the required balances of its and its subsidiaries’ primary operating and other accounts with SVB, and the Company continues to evaluate the SVB LSA. At June 30, 2023, the Company also held cash at Bank of America, N.A. of $1,500,000 and at PNC Bank, N.A. of $4,448,000. The Company continues to re-allocate its cash position across all three banks and explore an overall banking diversification strategy as well as additional access to lending facilities.
Note 6. 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. On November 17, 2021, 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 3,374,513 to 6,874,513. 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 June 30, 2023, there were 1,495,927 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
