Definition: "Sub-account" Means Different Things in the Two Types of VUL

"Sub-account" originated as a US variable life term. Premiums go into a separate account kept apart from the insurer's general account, and the separate account is divided into sub-accounts investing in different funds, whose value moves with the investment performance of the underlying funds (FINRA Notice 00-44, 2000-06-16). In Singapore the concept applies to two products of quite different form:

Dimension Retail VUL / investment-linked policy (ILP) High-net-worth self-directed VUL
Investment vehicle ILP sub-funds set up by the insurer (the fund range), priced in units A segregated custody account opened at a custodian bank nominated by the policy owner and accepted by the insurer, holding securities directly
Who selects the assets The policy owner picks from the list of funds the insurer offers The policy owner or their manager, within the Investment Mandate and Asset Parameters
Who manages The insurer and the fund managers it appoints The policy owner (self-managed) or an external licensed asset manager
Pricing Unit price, often with a bid-offer spread Daily valuation at the market value of the holdings
Key documents Product summary, Product Highlights Sheet (PHS), fund factsheets Product summary, Investment Mandate, Asset Parameters, custody and management agreements
Entry requirements Available to retail customers Usually Accredited Investors only; single premium; minimum premium per the product summary
Common regulation MAS Notice 307 sets disclosure, valuation, audit and investment guideline requirements for investment-linked policies Same

This article covers both types, with the emphasis on the high-net-worth self-directed type. Fund platforms, regular investment plans and disputes in retail ILPs are covered at the sister site ilp.com.sg; this site explains only how the two differ.

Retail Type: How the Insurer's Fund Range Works

A retail ILP can be summed up as "premiums become units, and charges sell units":

  • After the premium allocation is deducted, the premium buys units in ILP sub-funds. The insurance protection charge rises with age and is usually paid by selling units bought with premiums (MoneySense, 2026-09-28).
  • Sub-funds are run by fund managers appointed by the insurer, who charge a fund management fee. Units are bought at the offer price and redeemed at the bid price, and MoneySense notes that this bid-offer spread is typically about 5%, which covers distribution, marketing and general administration costs.
  • A limited number of fund switches each year are free; later switches carry a switching fee.
  • MAS Notice 307 requires insurers to value, audit and report on ILP sub-funds to MAS and to make disclosures, and sets standards for investment guidelines and borrowing limits (last revised 2021-06-28).
  • What the policy owner sees is "number of units × unit price", not individual securities.

The strengths of this form are a low entry threshold, standardised processes and a uniform disclosure format. The limitations are that the insurer decides the available range, existing holdings cannot be moved in, charges are mainly collected through spreads and unit deductions, and transparency depends on the Product Highlights Sheet.

High-net-worth Type: What Can Usually Go In Under a Self-directed Mandate

The "sub-account" of a high-net-worth VUL is a custody account in the name of the policy, and what can go in is decided by two documents: the insurer's Asset Parameters (common to all policies) and the policy's own Investment Mandate (agreed between the policy owner and the manager). The following are acceptance conditions commonly seen in the Singapore market; the insurer's documents prevail.

Asset class Common acceptance conditions Common restrictions
Cash and cash equivalents Held at the custodian in the policy currency or a permitted currency The account must maintain a minimum proportion (see below)
Listed shares Listed on an exchange the insurer recognises, sufficiently liquid and priced daily; a common requirement is membership of a major global index Single-holding limit; must not cause the insurer to cross substantial shareholding disclosure or mandatory takeover offer thresholds; related-party securities are restricted
Public bonds Publicly issued, custodiable and valued daily; investment grade is commonly required Single-issuer limit; contingent convertible bonds (CoCos) are often excluded
Funds and ETFs (collective investment schemes) Singapore-constituted schemes must be authorised by MAS and foreign-constituted schemes must be recognised; alternatively, a restricted scheme offered only to "relevant persons" under section 305(5) of the SFA, or requiring at least S$200,000 per transaction, which is exempt from the authorisation or recognition and prospectus requirements (MAS, 2026-10-05); the period from redemption to settlement is capped Leveraged, inverse and single-stock ETFs are usually excluded
Structured products Issuer rating, valuation and custody feasibility; usually approved one by one Lower aggregate cap for the category
Hedge funds and other alternative funds Assessed case by case Liquidity and valuation frequency are the key issues

A general principle: "a bank can trade it" does not mean "a VUL can accept it". Assets that the client already holds, or that a private bank can trade, must still be approved by the insurer one by one before they can enter the policy.

Assets That Usually Cannot Go In, and Why

The insurer's screening logic comes down to four questions: can it be sold, can it be valued, is leverage too high, and can it be held by an approved custodian. On that basis the following are usually excluded:

  1. Derivatives and leveraged instruments: options, futures, FX forwards, warrants, short sales through borrowed securities, and highly leveraged funds. The reasons are amplified risk and complex valuation and margin management, which conflict with the requirement that the account must always be able to pay charges.
  2. Restricted investment vehicles: leveraged, inverse and single-stock ETFs, crypto-asset and NFT-related instruments (including crypto ETFs), and contingent convertible bonds.
  3. Physical and non-public assets: real estate, physical commodities, private equity and private debt. They are hard to value daily, hard to hold in custody, and harder still to liquidate at market price when charges fall due.
  4. Pledged or non-custodiable assets: securities already pledged to a bank cannot be transferred in.
  5. Other exclusions: restricted related-party securities, sanctioned assets, special purpose vehicles backed by assets or mortgages, and underwriting commitments.

A common misunderstanding is a founder who wants to pay the premium with shares in their own company. Unlisted company shares count as private equity and are usually not accepted. Even for listed company shares, the single-holding concentration limit applies, the insurer may not be able to take the whole position the founder wishes to transfer, and a low-dividend holding may be unable to sustain ongoing charges.

Concentration Limits, Minimum Cash Ratio and Minimum Account Value

These three rules are the guardrails of a high-net-worth VUL account, and they are linked:

  • Concentration limits: percentage caps on a single holding and on a single asset class, by reference to account net value, usually tested at inception. The insurer bears the consequences of extreme swings in account value (policy lapse, benefit calculation), so concentration is restricted.
  • Minimum cash ratio: the policy fee, administration charge and cost of insurance are deducted from the account quarterly or monthly, and custody and management fees must also be paid in cash, so the account must keep a certain proportion of cash or cash equivalents. If it falls below that proportion, there is usually a grace period to top up, after which the insurer can sell assets to restore it.
  • Minimum account value: a common formulation is the higher of a fixed amount and a set percentage of the initial premium. Below it, funds must be added or the policy may be terminated.

The transmission chain is: market falls, account value falls, fixed charges take a larger share and cash is steadily drawn down, the cash ratio or account value hits its threshold, and a top-up requirement or forced sale follows. Specific ratios and amounts are product parameters, and the product summary and Investment Mandate documents prevail; this site does not quote figures from any product.

What an In-specie Transfer Means and What It Triggers

An in-specie transfer (also called an asset premium payment) means that, instead of selling first, securities the insurer has accepted are transferred from the original custodian to the policy's custody account and credited as premium at their valuation on the transfer date. The typical process:

  1. At the preliminary assessment stage, submit the list of assets proposed for transfer (asset class, ISIN, quantity, market value, current custodian and jurisdiction).
  2. The insurer pre-assesses each item and issues a conditional acceptance letter and transfer instructions.
  3. The policy owner notifies the original bank, and the insurer's operations team coordinates the transfer with the original custodian and the policy's custodian.
  4. Once the transfer completes, the assets are credited at valuation; any portion not accepted is replaced with cash or removed.

A transfer triggers the following: transfer-out fees at the original bank (usually borne by the client); trading or transfer fees at the policy's custodian (which may be deducted from the policy value); market movements during the transfer that change the premium finally credited; and a change of legal ownership, which in some tax jurisdictions may be treated as a disposal event, so obtain professional advice in your tax residence jurisdiction. Dividends and interest received after the transfer go into the policy account, and corporate actions are handled by the custodian. What a transfer does not remove is the need for cash. After paying in specie, the minimum cash ratio, charge deductions and minimum account value must still be met, and adding premium later with assets also requires approval and must meet the acceptance conditions.

Who Decides What to Trade and What the Insurer Reviews

Step Who Notes
Proposing trades The asset manager, or the self-managing policy owner Based on the Investment Mandate
Review The insurer Checks that the asset is on the eligible list, within concentration and class limits, free of related-party issues, and that the instruction comes from an authorised person
Execution and settlement The custodian Executes after verification and reports the fill or rejection
Viewing The manager Usually read-only access: holdings, transaction records, custodian notices

The insurer checks whether a trade follows the rules, not whether the investment is wise, fairly valued or well timed; nor does it give investment advice. Processing times are service targets rather than commitments, and neither execution time nor price is guaranteed. On the other side, when the account's cash is insufficient for charges or falls below the minimum, the insurer has the right to sell assets on its own initiative, and this usually cannot be excluded in the Investment Mandate.

Illustrated Returns and Asset-class Assumptions: How to Read Them

A Policy Illustration (also called a Benefit Illustration) projects account value and death benefit using an assumed rate of return and current charges. High-net-worth VULs usually allow the whole illustration to be run on an assumption chosen within a range, and may give different reference ranges by asset class (the insurer's documents prevail). Three points to remember when reading one:

  • The LIA member guidance (undated; it applies to protection-oriented single-premium and recurrent single-premium ILPs and to regular-premium ILPs) permits an illustration only for protection-oriented single-premium ILPs, meaning death and critical illness benefits together of at least 150% of the single premium paid. It requires an upper scenario (capped at 8%), a lower scenario (capped at 4%) and a 0% column, with a statement that the policy value may fall to zero, in which case the policy will terminate. A GIO-type VUL with a low sum assured may have no illustration at all; see Guarantees and non-guarantees.
  • An assumed rate of return is neither a promise nor equal to the policy's internal rate of return after charges. The underlying investments have no floor, so the account value can fall below the premiums paid, and past performance does not indicate future results.
  • Read the illustration together with the Investment Mandate. For a mandate made up mainly of investment-grade bonds, the high-scenario column says little about the future; it is more useful to see in which year the policy hits the minimum account value in the 0% column.
