Material Definitive Agreement regulatory
"Item 1.02 Termination of a Material Definitive Agreement."
A material definitive agreement is a legally binding contract that creates major, long‑term obligations or rights for a company, such as loans, asset sales, mergers, or supplier deals. Think of it like a mortgage or lease for a business: it can change future cash flow, risk and control, so investors watch these agreements closely because they can materially affect a company’s value, financial health and stock price.

Net asset value is the total value of an investment fund's assets minus any liabilities, divided by the number of shares or units outstanding. It represents the per-share worth of the fund, similar to how the value of a house is determined by its total worth after debts are subtracted.
