Age 70½ Default Provisions. If the Depositor does not choose any of the distribution methods under Article IV of this Custodial Agreement by the April 1st following the calendar year in which the Depositor reaches age 70½, distribution shall be determined based upon the distribution period in the uniform lifetime distribution period table in Regulation section 1.401(a)(9)-9. However, no payment will be made until the Depositor provides the Custodian with a proper distribution request acceptable to the Custodian. The Custodian reserves the right to require a minimum balance in the account in order to make periodic payments from the account. Upon receipt of such distribution request, the Depositor may switch to a joint life expectancy in determining the required minimum distribution if the Depositor’s spouse was the sole beneficiary as of the January 1st of the distribution calendar year and such spouse is more than 10 years younger than the Depositor.
