"The shares are held as indirect ownership through IRAs"

Individual Retirement Accounts (IRAs) are personal investment accounts designed specifically to save for retirement, offering tax advantages that help savings grow faster than in a regular account. Think of an IRA as a dedicated piggy bank where contributions and earnings get special tax treatment—either tax-deferred or tax-free depending on the type—making it important for investors who want to lower current or future taxes while holding stocks, bonds, and funds for long-term goals.
