Most Indexed Universal Life plans are sold around one central idea: build cash value while maintaining lifelong insurance protection.

Manulife Signature Indexed Income takes that concept in a different direction.

Its key proposition is lifetime monthly income, supported by a combination of Fixed Account and Index Account crediting, together with whole-life protection and legacy-planning features.

That can sound compelling, particularly for someone with substantial USD capital who wants more than simply leaving behind a death benefit.

But there is an important question to answer first:

Where does that monthly income actually come from — and how much of it is guaranteed?

The answer matters.

The policy has a guaranteed minimum Fixed Account crediting rate and several contractual safeguards, but the monthly income itself is linked to the interest generated by the policy after monthly deductions.

That means future index performance, crediting rates, charges and Policy Value all matter.

Here is how Manulife Signature Indexed Income actually works.

What Is Manulife Signature Indexed Income?

Manulife Signature Indexed Income is a USD-denominated, non-participating Universal Life insurance plan designed primarily for high-net-worth clients.

Its objectives combine:

• lifetime monthly income;
• potential Policy Value growth;
• index-linked crediting;
• whole-life death protection;
• estate and legacy planning.

Premiums can be paid through:

• a Single Premium; or
• Multi-pay terms ranging from 2 to 10 years.

Entry is available from age 15 days to age 70, with facultative consideration potentially available up to age 80.

Both Guaranteed Issuance Offer and Full Medical Underwriting routes are available, subject to the applicable eligibility requirements.

The core proposition is therefore not simply:

“Invest in an index.”

It is:

Use a Universal Life structure to generate potential recurring income while retaining Policy Value and a death benefit.

Whether that works well depends heavily on the mechanics underneath.

How Your Premium Is Allocated

After applicable Premium Charges, Net Premium can be split between two main accounts:

• Fixed Account
• Index Account

Manulife provides five preset allocation combinations:

Option	Fixed Account	Index Account
1	0%	100%
2	25%	75%
3	50%	50%
4	75%	25%
5	100%	0%

Reallocation between the Fixed and Index Accounts becomes available from two years after policy issuance.

This lets the policyowner choose how much emphasis to place on more predictable Fixed Account crediting versus market-linked Index Account crediting.

How the Fixed Account Works

The Fixed Account provides the more predictable side of the policy.

The supplied product information shows:

• current declared crediting rate: 4.20% p.a.
• guaranteed minimum crediting rate: 2.00% p.a.

Interest accrues daily and is credited monthly.

The distinction between the two numbers matters.

The 4.20% rate is the current declared rate.

The 2.00% rate is the contractual minimum.

And neither should automatically be interpreted as the net return on the entire policy.

Policy charges and monthly income distributions still affect the eventual Policy Value.

How the Index Account Works

The Index Account uses one-year point-to-point segments.

The supplied parameters include:

• 0% floor
• an illustrated 9.00% p.a. cap
• guaranteed minimum cap of 3.00% p.a.
• interest credited at Index Segment maturity.

The 0% floor means negative index performance does not create negative index interest for the relevant segment.

But there is an important distinction:

A 0% Index Account floor does not mean the entire Policy Value cannot decline.

Monthly policy deductions continue.

Income may also be paid out from the policy.

So a period could look like:

Index crediting: 0%
Monthly charges: deducted
Income payouts: made where applicable
Policy Value: may decline

The floor protects the index-crediting calculation.

It does not create a 0% floor beneath the entire insurance policy.

What Is the S&P PRISM Index?

One of the most interesting elements of Signature Indexed Income is the S&P PRISM Index.

Unlike simply tracking the S&P 500, PRISM is a multi-asset strategy built around three components:

Equities

S&P 500 Total Return exposure.

Fixed Income

S&P 10-Year U.S. Treasury Note Futures Excess Return exposure.

Commodities

S&P GSCI Excess Return exposure.

The objective is to combine different asset classes within a volatility-controlled index rather than relying solely on US equities.

Why PRISM Uses Volatility Control

The S&P PRISM Index targets approximately:

5.5% volatility

The strategy dynamically manages its exposures in an attempt to maintain that volatility target.

Why does that matter for an IUL?

Because the insurer does not simply buy the index for you.

It needs to support the index-crediting mechanism.

Lower-volatility index structures can make the options used to provide index-linked crediting less expensive.

The supplied product material illustrates this with an option-cost comparison of roughly:

US$0.70 for the volatility-managed strategy

versus:

US$1.00 for an unmanaged S&P 500 strategy

This cost difference can help support a higher Participation Rate.

PRISM Participation Rate: Why More Than 100% Is Possible

The supplied product information illustrates PRISM Participation Rates of approximately:

136% to 150%

with a guaranteed minimum Participation Rate of:

70%

A Participation Rate above 100% does not mean your premium earns 136% or 150%.

It means the relevant index performance is multiplied according to the policy’s crediting formula.

The important distinction is:

Index performance ≠ Participation Rate ≠ Policy return.

A high Participation Rate can improve credited interest when the underlying index performs positively.

But future index performance itself is not guaranteed.

Neither are illustrated Participation Rates above the contractual minimum.

Does PRISM Perform Better Than the S&P 500?

The supplied backtesting from 2018 to 2024 indicates that the S&P PRISM sub-account generated higher crediting rates than the capped S&P 500 sub-account over approximately 62% of the tested segment periods during volatile or relatively flat markets.

That is interesting.

But it should not be interpreted as a prediction that PRISM will outperform in 62% of future periods.

Backtesting tells you how a rules-based strategy would have behaved under historical conditions.

It does not tell you what the next 10 or 20 years will produce.

PRISM’s real attraction is therefore its different return structure, not a promise that it will outperform the S&P 500.

Automatic Premium Spread: Entering Over 12 Months

Policyholders can also opt for Automatic Premium Spread (APS).

Instead of allocating all Index Account-directed Net Premium into one starting date, APS divides it across:

12 monthly Index Segments over 12 months

This reduces reliance on one market-entry date.

But it is important not to call this a guaranteed return-enhancement strategy.

If markets rise strongly immediately after the policy begins, gradual allocation can also underperform investing the entire amount at the start.

APS is better understood as:

timing diversification

rather than:

guaranteed better performance.

How the Lifetime Monthly Income Actually Works

This is the section prospective buyers should understand most carefully.

Signature Indexed Income allows monthly income to begin from Policy Year 2 through Policy Year 21, depending on the selected premium-payment term.

But the income is not simply a guaranteed fixed coupon detached from policy performance.

The payout is derived from crediting interest generated by the Fixed and Index Accounts after monthly policy deductions.

In Policy Years 2 and 3, an Income Factor of 20% applies to the monthly income calculation.

This means the actual income outcome depends on how the policy performs.

Strong crediting can support higher distributions.

Weak crediting produces a different result.

That is why the phrase “lifetime monthly income” should not automatically be interpreted as:

“A fixed monthly amount guaranteed for life.”

The underlying mechanics matter.

What Happens to the Monthly Income?

Policyholders can either:

• receive the monthly payout; or
• leave it inside the policy’s Income Accumulation Account (IAA).

The IAA currently earns a non-guaranteed interest rate of:

2.00% p.a.

If the monthly payout is below:

US$300

it is automatically directed into the IAA rather than paid out.

This provides some flexibility between taking income now and retaining it within the policy.

The Policy Value Booster: A Major Part of the Structure

Signature Indexed Income also provides a Policy Value Booster.

The booster is equivalent to:

1.46% p.a. of the Face Amount

and is credited annually to the Fixed and Index Accounts from the end of Policy Year 2 through Policy Year 25.

This can materially affect illustrated Policy Value.

But there is an important condition:

The Policy Value Booster does not become fully vested immediately.

Vesting begins from Policy Year 11.

It only becomes:

100% fully vested at the end of Policy Year 30

This makes the Booster a strongly long-term feature.

Someone evaluating an early surrender should therefore not assume every Booster amount shown within Policy Value is fully available without reference to the vesting rules.

Guaranteed vs Non-Guaranteed: What Is Actually Locked In?

For a plan combining lifetime income with index-linked crediting, this is one of the most important tables to understand.

Feature	Guaranteed?	What It Means
2.00% p.a. Fixed Account minimum	Yes	Fixed Account crediting cannot fall below the contractual minimum
0% Index Account floor	Yes	Negative index performance does not generate negative segment crediting
Minimum Index Account cap of 3.00% p.a.	Yes	The applicable cap will not fall below the contractual minimum stated
PRISM minimum Participation Rate of 70%	Yes	Future PRISM Participation Rates remain subject to this minimum
Current Fixed Account rate of 4.20% p.a.	No	It is currently declared and may change
Illustrated 9.00% cap	No	Future declared caps may differ, subject to the minimum
Illustrated PRISM Participation Rate of 136%–150%	No	These should not be assumed to continue permanently
Future S&P PRISM performance	No	Index returns depend on future markets
Monthly income amount	No fixed amount stated as guaranteed	Payouts depend on crediting and policy deductions
IAA interest rate currently 2.00% p.a.	No	Current IAA interest is non-guaranteed
Illustrated future Policy Value	No	Depends on future crediting and policy mechanics

The practical takeaway is straightforward:

The policy contains guarantees, but much of the upside — and the income generated from that upside — remains dependent on future experience.

What Does the Surrender Value Floor Actually Protect?

Signature Indexed Income also includes a Surrender Value Floor (SVF).

The floor is calculated using the higher of zero or:

Total Premiums Paid − a specified percentage of Face Amount

The supplied schedule begins at 20% of Face Amount during Policy Years 1 to 10 and scales to 40% by Policy Year 30.

This provides a contractual floor for full surrender.

But it should not be described as:

“100% capital guaranteed.”

The calculation itself allows a deduction based on a percentage of Face Amount.

The SVF therefore provides a defined contractual minimum, but that minimum is not necessarily equal to all premiums paid.

How the Death Benefit Works

The policy provides whole-life protection.

The Death Benefit is based on the highest of:

1. 105% of total premiums paid, after adjusting for applicable withdrawals, Terminal Illness claims and monthly income payouts;
2. Policy Value;
3. Surrender Value Floor;

less applicable policy debt.

This structure links the protection benefit to both premiums paid and the evolving value of the policy.

It also demonstrates why taking monthly income and making withdrawals can affect the eventual legacy outcome.

Income and legacy are connected.

They should not be evaluated separately.

Terminal Illness Benefit

The policy provides an accelerated Terminal Illness benefit for qualifying diagnoses before age 99.

The maximum accelerated payout is:

US$2 million

subject to the applicable policy conditions.

This allows part of the death benefit to become available earlier in a qualifying terminal-illness scenario.

Change of Life Insured

From two years after policy issuance, the Life Insured can be changed.

For individually owned policies, this can be done up to:

2 times

For corporate-owned policies:

unlimited changes

are permitted subject to the relevant policy rules.

This can be useful for longer-term estate or corporate planning where the insured person may need to change over time.

What Does Signature Indexed Income Cost?

The policy contains several layers of charges.

These should be considered together rather than focusing only on the Index Account crediting rate.

Premium Charge

A Premium Charge is deducted before premium enters the policy accounts.

The supplied schedule includes:

Policy Year	Premium Charge
Year 1	8.0%
Year 2	7.5%
Year 3	7.0%
Year 4	6.5%
Year 5	6.0%
Year 6	5.5%
Year 9 onwards	4.0%

The supplied data does not specify the exact Year 7 and Year 8 rates, so they should be checked against the applicable policy documents before illustration or advice.

This charge means not every dollar of gross premium begins compounding.

Policy Fee

A monthly Policy Fee of:

US$2.108333 per US$1,000 of Face Amount

applies during the first 25 policy years.

Because this is linked to Face Amount, the actual dollar charge depends on the size of the policy.

Administration Fee

An Administration Fee of:

0.03% of Policy Value per month

is charged while the policy remains in force.

As Policy Value increases, the dollar amount of this charge also increases.

Surrender Charge

A Surrender Charge applies during the first:

11 policy years

This reinforces the long-term nature of the product.

The Key Trade-Off: Income Today vs Policy Value Tomorrow

Signature Indexed Income has an interesting proposition because it attempts to combine:

current income + long-term Policy Value + whole-life legacy

But those objectives are connected.

Monthly income comes from the economics of the policy.

Taking income out means that value is no longer remaining inside the policy to compound.

Similarly, charges continue to be deducted.

That does not make the strategy inappropriate.

It simply means the correct question is not:

“How much income can I receive?”

It is:

“How much income can the policy distribute while still maintaining the Policy Value and legacy outcome I want?”

For someone considering this for decades, that is a much more useful conversation.

Pros and Cons of Manulife Signature Indexed Income

Potential Strengths	Potential Limitations
Lifetime monthly income feature	Monthly income amount is linked to policy crediting and deductions
Fixed and Index Account allocation choices	More complex than a simple income product
2.00% minimum Fixed Account rate	Does not equal a guaranteed 2% net policy return
0% Index Segment floor	Policy Value can still decline after charges and payouts
S&P PRISM multi-asset strategy	Future PRISM performance is non-guaranteed
PRISM Participation Rate can exceed 100%	Illustrated rates above the 70% minimum are not guaranteed
Automatic Premium Spread	Does not guarantee better returns
1.46% Policy Value Booster	Booster takes many years to become fully vested
Surrender Value Floor	Does not mean all premiums are capital guaranteed
Whole-life legacy protection	Income withdrawals can affect eventual legacy values
Change of Life Insured	Long-term commitment required
Single-pay or 2–10 year Multi-pay	Premium Charges apply to each premium

Who May Find Signature Indexed Income Worth Considering?

The policy may be worth examining if you:

• have substantial long-term USD capital;
• want potential recurring income rather than only leaving a death benefit;
• still want whole-life estate protection;
• value a combination of Fixed and Index Account crediting;
• have a sufficiently long time horizon for the Booster vesting structure;
• are comfortable with non-guaranteed index-linked outcomes;
• want flexibility to retain or withdraw monthly income;
• value Change of Life Insured flexibility for family or corporate planning.

It is particularly important that the policy be viewed as a long-term income-and-legacy structure, rather than a short-term yield product.

Who Should Think Twice?

You should compare alternatives carefully if you:

• require a fixed guaranteed monthly income amount;
• need significant short-term liquidity;
• want low-cost direct market exposure;
• are buying mainly because of a high illustrated PRISM Participation Rate;
• assume a 0% floor guarantees your capital;
• expect the entire Policy Value Booster to be immediately available;
• do not need the life-insurance or estate-planning component;
• are uncomfortable with a long surrender period or complex policy mechanics.

What You Should Pay Attention To

1. “Lifetime Income” Does Not Automatically Mean “Guaranteed Fixed Income”

Understand exactly how the payout is calculated under your Policy Illustration.

2. The 0% Floor Applies to Index Crediting

Policy deductions and income payouts still affect Policy Value.

3. Current Rates Are Not the Same as Guaranteed Rates

Compare:

• 4.20% current Fixed Account vs 2.00% minimum;
• illustrated 9% cap vs 3% minimum cap;
• illustrated PRISM participation of 136%–150% vs 70% minimum.

4. The Booster Has a Long Vesting Schedule

100% vesting only occurs at the end of Policy Year 30.

5. Income and Legacy Compete for the Same Policy Economics

More value distributed today means less value remaining inside the policy.

6. Look Beyond Backtested PRISM Results

Historical backtesting may demonstrate how the strategy behaved in past conditions, but it does not guarantee future outcomes.

7. Charges Continue

Premium Charges, Policy Fees and Administration Fees affect the amount that ultimately compounds.

FAQs

Is Manulife Signature Indexed Income an IUL?

It is a USD-denominated, non-participating Universal Life policy incorporating index-linked crediting and a lifetime monthly income feature.

Is the monthly income guaranteed?

The supplied product information states that monthly payouts are derived from Fixed and Index Account crediting after monthly policy deductions.

A fixed lifetime monthly payout amount is therefore not identified in the supplied information as guaranteed.

Does the 0% floor mean I cannot lose money?

No.

The 0% floor prevents negative Index Segment crediting.

Policy charges and monthly income payouts can still reduce Policy Value.

Is the current 4.20% Fixed Account rate guaranteed?

No.

The current declared rate is 4.20% p.a.

The contractual minimum is 2.00% p.a.

Is the PRISM Participation Rate guaranteed at 136% or 150%?

No.

Those are illustrated Participation Rates in the supplied data.

The guaranteed minimum is 70%.

Is the 9% Index Account cap guaranteed?

No.

The supplied material identifies 9% as an illustrated cap and a contractual minimum cap of 3%.

Is the Policy Value Booster guaranteed to be fully available immediately?

No.

The Booster follows a vesting schedule beginning from Policy Year 11 and becomes fully vested only at the end of Policy Year 30.

Does the Surrender Value Floor guarantee all my premiums?

Not necessarily.

The SVF uses a contractual calculation based on premiums paid less a specified percentage of Face Amount.

It should not be interpreted as a simple 100% capital guarantee.

Final Verdict: An Income IUL — But Understand Where the Income Comes From

Manulife Signature Indexed Income is interesting because it combines three objectives that are normally discussed separately:

monthly income

long-term Policy Value

whole-life legacy protection

The S&P PRISM strategy, 0% Index Segment floor, Policy Value Booster and flexible Fixed/Index Account allocation give the policy several mechanisms for supporting those objectives.

But the monthly income does not exist independently of the policy.

It ultimately depends on the crediting generated by the Fixed and Index Accounts after policy deductions.

And the headline figures need context:

A 136%–150% illustrated PRISM Participation Rate is not guaranteed permanently.

A 0% floor does not prevent Policy Value from declining.

A 1.46% Policy Value Booster is not immediately fully vested.

And lifetime monthly income should not automatically be interpreted as a fixed guaranteed monthly payout for life.

For a high-net-worth client who genuinely wants to combine income, estate planning and long-term USD wealth, that structure may be worth examining.

But the decision should be made by stress-testing the income and Policy Value together — not by looking only at the most attractive illustrated scenario.

Considering Manulife Signature Indexed Income?

If you are exploring Signature Indexed Income, the most useful comparison is not simply its illustrated monthly payout.

We can help you examine the guaranteed and non-guaranteed values, S&P PRISM mechanics, Participation Rate, Policy Value Booster, charges, surrender values and projected income under different assumptions.

We can also compare the structure against other indexed and income solutions using the same premium assumptions, so you can see whether the income comes at an acceptable cost to your long-term Policy Value and legacy.
