During the accumulation phase of a deferred annuity, what is happening?

Explanation

The accumulation (pay-in) phase is when the owner contributes premiums and the annuity's value grows on a tax-deferred basis, before income payments begin. Making periodic income payments describes the annuitization (payout or distribution) phase, not accumulation. Surrendering the contract ends it early. Paying a death benefit occurs if the owner/annuitant dies, which is a separate event. An immediate annuity skips accumulation, but a deferred annuity has this pay-in period first.
