What Is a RILA? Registered Index-Linked Annuities Explained

A registered index-linked annuity, also sold under names such as structured annuity, buffered annuity, or index-linked variable annuity, is a contract with a life insurance company in which your premium earns interest based on the movement of a market index over a set term. You do not own the index or any stocks; the insurer credits interest according to a formula in the contract.

The word "registered" is the key. Because a RILA can lose value, it is a security registered with the Securities and Exchange Commission. It is sold with a prospectus, by an agent who also holds a securities registration through a broker-dealer regulated by FINRA. A fixed index annuity, which cannot lose value to the market, is an insurance product only and is regulated by state insurance departments alone.

RILAs exist because fixed index annuity caps are often low, and variable annuity losses are unlimited. The RILA offers a middle path: you accept a defined, limited share of losses, and the insurer can afford to offer more upside.

Takeaway: RILA in one line: index-linked growth with higher caps than an FIA, bought by agreeing to absorb part of a market loss.

Every RILA protects you from losses in one of two ways, and the difference matters more than the cap.

A buffer absorbs the first portion of a loss. With a 10% buffer, if the index falls 8% over the term, the insurer absorbs all of it and you lose nothing. If the index falls 15%, the insurer absorbs the first 10% and you lose 5%. If the index falls 40%, you lose 30%. Buffers protect well in ordinary down years and less well in a severe crash.

A floor limits your loss to a set maximum. With a 10% floor, you absorb losses up to 10% and the insurer absorbs everything beyond that. If the index falls 8%, you lose 8%. If it falls 40%, you lose 10%. Floors protect poorly in mild declines and well in a crash. Because a floor gives the insurer more risk in ordinary years, floor contracts usually carry lower caps than buffer contracts.

The table shows the arithmetic for both designs using illustrative index results.

Takeaway: Buffers are for people who expect ordinary corrections; floors are for people who want a hard limit in a crash. Pick the design before you compare caps.

On the upside, a RILA credits interest according to one or more of the same devices a fixed index annuity uses. A cap is the maximum interest you can receive in a term regardless of how far the index rises. A participation rate is the share of the index gain you receive, sometimes above 100% in exchange for less protection. Some contracts use a trigger or step rate that pays a fixed percentage whenever the index finishes flat or up.

Interest is calculated and credited at the end of the term, which may be one, three or six years. Longer terms usually carry higher caps because the insurer can hedge them more cheaply, but your money is committed to that segment for the full term. Withdrawing from a segment before it ends receives an interim value, which is the insurer's calculation of what your position is worth mid-term and can be less than the premium even when the index is up.

The insurer resets caps and participation rates at the start of each new term based on interest rates and option prices, so the terms you see in a quote apply only to the first segment. The prospectus states the minimum cap the insurer can ever set, which is the number that protects you over the long run.

The three index-oriented annuity designs differ mostly in how much loss you accept and how much gain you can keep.

Takeaway: If you would not accept any loss, an FIA is the right shelf. If you can accept a defined loss for more upside, a RILA is. If you want full market exposure, look at a variable annuity or an ordinary brokerage account.

Most RILAs carry no stated annual fee; the insurer earns its margin through the caps and buffers it sets. Optional riders, such as a return-of-premium death benefit or an income benefit, add annual charges when elected. Read the fee table in the prospectus rather than relying on the word "no fee".

RILAs have a surrender charge schedule like other deferred annuities, typically 3 to 6 years, with a free withdrawal allowance each year, commonly 10% of the account value. Two additional mechanics matter: the interim value adjustment applies to any money taken out of an index segment before the term ends, and, in some contracts, a market value adjustment applies on top of the surrender charge. Together they mean a RILA is best held to the end of each segment and, ideally, to the end of the surrender period.

At the end of each term you can usually move money among the contract's segments and crediting strategies, or into a fixed-rate account inside the contract, without a charge. That flexibility lets you dial protection up or down as your needs change without buying a new annuity.

A RILA follows deferred-annuity tax rules. Interest credited inside the contract is not taxed until withdrawn. Withdrawals from a non-qualified RILA are treated as earnings first and taxed as ordinary income; taxable amounts taken before age 59 and a half generally owe a 10% additional federal tax. If the RILA is held inside an IRA, the IRA's rules apply instead, including required minimum distributions.

One consequence is worth spelling out. Index gains in a taxable brokerage account can qualify for long-term capital gains rates; the same gains credited inside a RILA are ordinary income when withdrawn. The deferral is valuable, but the eventual rate is higher, so the comparison to simply owning an index fund depends on your tax bracket and how long the money stays in the contract.

A RILA suits a buyer in the years around retirement who wants more growth than a fixed index annuity offers, can tolerate a defined loss, and will not need the money before each index term ends. It also suits money already in a variable annuity that is out of its surrender period, where the owner wants to reduce downside without giving up market participation entirely; a tax-free 1035 exchange can move it.

It fits poorly for anyone who cannot accept a loss of principal, for money that may be needed during the surrender period, and for buyers who do not understand the difference between a buffer and a floor. Because the product is a security, you should receive and read the prospectus, and the representative must have a reasonable basis to believe it is suitable for you.

• Likely a fit: growth-minded pre-retirees, defined loss tolerance, a 3-to-6-year holding horizon, or an existing variable annuity you want to de-risk.
• Likely not a fit: no tolerance for loss, near-term liquidity needs, or a preference for the simplicity of a fixed rate.

Takeaway: Ask the representative two questions: is this a buffer or a floor, and what is the lowest cap the contract allows in future terms? The prospectus answers both.
