"gift of Common Stock to a charitable donor-advised fund"

A donor-advised fund is a charitable giving account that lets an individual or family deposit cash, stock, or other assets now, get an immediate tax benefit, and then recommend grants to charities over time. Think of it like a private charitable bucket you control without running a charity yourself; investors care because it’s a tax-efficient way to give appreciated securities, can change when and how donated shares enter the market, and affects personal and corporate tax planning.
