independent director financial
"The Board has determined that Mr. Greene is an “independent” director under the Nasdaq Stock Market rules."
An independent director is a member of a company's board of directors who is not involved in the company's day-to-day operations and has no significant relationships with the company that could influence their judgment. Their role is to provide unbiased oversight and ensure the company is managed in the best interests of all shareholders. This helps build trust and confidence among investors by promoting transparency and accountability.
2020 Stock Incentive Plan financial
"he received, under the Company’s 2020 Stock Incentive Plan, an option to purchase 57,463 shares"
change in control financial
"In the event of a change in control of the Company, the vesting schedule of the option will accelerate in full."
A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.
indemnification agreement financial
"Mr. Greene will enter into the Company’s standard form of indemnification agreement."
An indemnification agreement is a contract in which one party promises to cover losses, costs, or legal claims that another party might face, acting like a tailored safety net or private insurance policy. For investors, it matters because such agreements shift potential financial risk away from a company or its officers and onto the indemnifier, which can affect a company’s future liabilities, cash flow and how risky the investment appears during deal-making or litigation.
