Key Terms

2 terms

Rule 10b5-1 plan regulatory

"No Rule 10b5-1 plan is reported for the sale."

A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.

donor advised fund financial

"gift to a charitable 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.
