foreign private issuer regulatory
"The Issuer is a foreign private issuer as defined under Rule 3b-4"
A foreign private issuer is a company organized outside the United States that meets tests showing it is primarily foreign-controlled and therefore qualifies for a different set of U.S. reporting rules. For investors, that means the company files less frequent or differently formatted disclosures with U.S. regulators and may follow home-country accounting and governance practices, so buying its stock is like dining at a well-reviewed restaurant that follows its home kitchen’s rules instead of the local menu — you get access but should check what standards apply.
short-swing profit recovery provisions regulatory
"the Reporting Person is exempt from the short-swing profit recovery provisions"
Section 16(b) regulatory
"short-swing profit recovery provisions of Section 16(b) of the Exchange Act"
A federal rule that requires company insiders—like officers, directors and large shareholders—to return any profits made from buying and selling the company’s stock within a six-month window. It matters to investors because it discourages short-term trades that could exploit non-public information and helps protect outside shareholders by creating a simple, enforceable way to recover unfair gains, much like a rule stopping someone from flipping a limited-edition item for quick profit after getting early access.
restricted stock units (RSUs) financial
"consist of shares underlying RSUs that were granted to the Reporting Person"
Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

No. Several rows, including certain ordinary share and option holdings, are footnoted as informational only, stating that no transactions were effected for those securities; they simply disclose existing positions.

How is the spouse’s ownership of MDWD shares treated in this Form 4?

The trades in ordinary shares are reported as indirect ownership "By spouse", meaning the shares are held by Rubinstein’s spouse but are attributed to him for reporting purposes under the securities rules.
