Key Terms

4 terms

bona fide gift financial

"Transaction code G is described as a bona fide gift"

A bona fide gift is a genuine, voluntary transfer of money, property, or benefits from one party to another made without expectation of repayment, services, or hidden conditions. Investors care because such gifts can affect company disclosures, related‑party transaction rules, tax treatment, and perceived conflicts of interest; think of it like someone giving you a present with no strings attached — but on a corporate scale, auditors and regulators need to verify it really is unconditional.

Donor Advised Fund financial

"Represents a charitable donation of shares to a Donor Advised Fund"

A donor advised fund is a charitable savings account you fund with cash or assets (including stocks) that lets you take an immediate tax benefit while recommending when and which charities receive grants over time. Think of it like a dedicated piggy bank for giving: you get tax relief when you put money in, can avoid selling appreciated securities and triggering capital gains, and still control the timing and recipients of donations, which affects tax planning, portfolio decisions, and public giving signals.

beneficial ownership financial

"Each of Heard Capital LLC and the Reporting Person disclaims beneficial ownership"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

pecuniary interest financial

"except to the extent of his or its pecuniary interest therein"
