Level 1 flows of an asset owner: the institutions that own the capital, with a FTSE 100 life insurer (GBP 100,000,000,000 of annuity assets under the matching adjustment, the bulk annuity business as the growth engine, an in-house asset manager with GBP 1,000,000,000,000 under management running the LDI and the index businesses for the pension schemes, a workplace pensions and retail business, Solvency UK, listed in London, illustrative) as the worked example, grouped by function (liabilities and ALM, investing, funding, liquidity and collateral, operations and custody, control and regulation). Each diagram follows one flow with the insurer at the center, the participants, the board and the actuary on one side, the managers, the dealers, the market, the custodian and the regulator on the other; the strip above it is the deal. Columns are the parties, rows the phases; numbered steps are messages, deliveries, payments or reports between them, with the channel or system in the pill. Hover a step for the detail, click it or use the walkthrough to be taken through the diagram step by step. The managers’ side of the same flows is on the buy-side page, the dealers’ side on the sell-side pages, the issuers’ side on the corporate treasury page, the rails on the market infrastructure page; the US flag opens the same cycle for a US life insurer.

How the diagrams work, the flow common to all 16 diagrams, a map of the flows, which entity books each and what it takes in funding, capital and reporting, and a glossary.
What the annuity book is and how it is managed: the bulk annuities written for the pension schemes, the insurer buying a scheme’s promises with its gilts; the matching adjustment portfolio that turns the spread on long-dated credit into capital under Solvency UK; and the longevity reinsurance that passes most of the risk of the members living longer to the global reinsurers.
LiabilitiesThe bulk annuities and the individual annuities: fixed or inflation-linked pensions for life, no surrender option, the longevity and the credit as the main risks.
DecisionThe pricing committee on each deal within the new business appetite; the MA portfolio within the PRA’s permission; the reinsurance strategy and the limits by the board.
ExecutionThe quote, the exclusivity and the policy with the scheme’s adviser; the assets bought and restructured by the in-house manager; the treaties with the reinsurers.
SettlementThe premium in gilts through CREST and cash by CHAPS; the MA assets into the designated custody accounts; the reinsurance net by CHAPS and the collateral at a custodian.
ControlThe SCR, the risk margin and the MA under Solvency UK; the matching tests and the attestation; the QRTs, the SFCR and the MALIR to the PRA; IFRS 17 in the accounts.
How the money is invested: the private credit the in-house manager originates for the matching adjustment portfolio; the LDI funds it runs for the pension schemes that have not yet bought out, with their leverage and their collateral; the with-profits and the unit-linked funds that belong to the policyholders; and the gilt and credit desk that buys for the annuity fund and the LDI funds in the auctions and the secondary market.
LiabilitiesThe annuities the MA portfolio backs; the schemes’ liabilities the LDI funds hedge; the policyholders’ own funds in the with-profits and the unit-linked business.
DecisionThe CIO’s pipeline and the credit committee; the trustees’ hedge ratio with their consultant; the PPFM and the bonus declaration; the portfolio managers’ orders.
ExecutionThe origination with the borrowers and the agents; the repo and the swaps with the dealers; the fund links and the mandates; the GEMMs, the DMO and the platforms.
SettlementThe drawdowns by CHAPS and the notes in Euroclear; the cleared swaps at LCH and the gilts in CREST; the funds’ custody and the unit registers; the agent lending.
ControlThe PRA’s reviews of the internal ratings; the LDI resilience standard; the Consumer Duty and the Value for Money framework; the FCA’s best execution and market abuse rules.
How the insurer funds its growth and keeps its liquidity: the funded reinsurance that sends part of an annuity block and its assets to an offshore reinsurer against a collateral trust; the daily collateral of the swaps that hedge the annuity book, with the gilt repo and the buffer sized against a 2022-style shock; and the Tier 2 and Restricted Tier 1 notes written to the Solvency UK tiering rules.
LiabilitiesThe annuity blocks written and their capital strain; the liabilities’ rate and inflation exposure the swaps hedge; the capital the new business needs.
DecisionThe board’s limits on the funded reinsurance and the recapture plan; the liquidity risk appetite and the buffer; the capital plan and the solvency target.
ExecutionThe treaty with the reinsurer and the premium in assets; the swaps dealt and cleared at LCH and the gilt repo; the notes drawn off the EMTN program with the joint lead managers.
SettlementThe premium through CREST and Euroclear and the collateral into the trust; the variation margin in cash every morning; the notes in the ICSDs at T+5.
ControlSS5/24 and the recapture scenario of LIST 2025; SS5/19 and the liquidity data; the tier limits each quarter and the PRA’s non-objection to the calls.
What happens after the decisions: the custody of the insurer’s portfolios with the matching adjustment portfolio kept apart and its cash flows fed to the actuaries; the payroll of hundreds of thousands of annuitants that a bulk annuity book becomes; and the monthly collection, unit allocation and transfers of the workplace pension business.
LiabilitiesThe annuity payments promised for decades; the members’ unit-linked pots; the data on each policy and each asset that the reserves and the matching rest on.
DecisionThe outsourcing of the custody and the administration; the payroll and the increase rules copied from the schemes; the employers’ choice of the scheme.
ExecutionThe trades instructed to the custodian; the monthly payroll run with PAYE; the contributions collected and the units allocated.
SettlementCREST and the ICSDs for the securities; Bacs for the pensions and the contributions; the transfer network for the pots.
ControlSS2/21 and the operational resilience; the Consumer Duty, HMRC and the FSCS; the IGC, the Value for Money framework and the dashboards.
How the insurer is measured and supervised: the Solvency UK reporting that values the business on the regulator’s rules and puts a senior manager’s name on the matching adjustment; the PRA’s supervision with the named senior managers, the yearly letter, the thematic reviews and the published stress test; and the IFRS 17 results that defer the profit of each buy-in into the contractual service margin.
LiabilitiesThe annuity liabilities valued three ways: the Solvency UK best estimate with the MA, the IFRS 17 fulfilment cash flows with the CSM, and the economics the pricing used.
DecisionThe board’s ownership of the model, the MA attestation, the SMCR responsibilities, the accounting judgments and the dividend.
ExecutionThe quarterly templates and the yearly SFCR, RSR and ORSA; the stress test submissions; the half-year and annual close.
SettlementThe filings through the Bank’s portal; the publications on the website and the RNS; the dividend through the registrar.
ControlThe PRA’s periodic letter and its tools; the published LIST 2025 results; the auditors, the FRC and the FCA’s disclosure rules.
How to read a diagram
Columns are the partiesThe policyholders, the members and the sponsors on the left, the board, the actuary and the parent group, the asset owner in olive at the center (the subject of every diagram), the managers and the desks, the dealers and the banks, the issuers and the market, the custodian and the rails, and the PRA, the FCA and the Pensions Regulator on the right.
Rows are the phasesTime runs down the page in the flow’s own cycle: the years of a liability, the annual policy, the quarterly allocation, the day of a trade, the settlement, the quarter-end books, the yearly filings. The band label gives the timing.
Arrows are stepsNumbered in order. Solid arrows are messages, deliveries or payments; dashed ones are standing flows like reports and reviews; two-headed ones are exchanged or negotiated. Boxes on the owner’s own lifeline are what it does internally: a valuation, an allocation, a reconciliation.
Pills are the channelAmber for voice and chat, blue for the platforms and portals (Bloomberg, the manager and custodian portals), rose for SWIFT messages, grey for the rails and the filings, teal for market data, lavender for the owner’s own systems (the ALM model, the IBOR, the policy administration). Each pill shows a one-line definition on hover.
The strip is the dealAbove each diagram the worked example strip gives the deal: the liability or the asset, the size, the counterparties, the settlement, the capital and the accounting, the reporting. Hovering a step shows the full detail; clicking it opens the walkthrough.
The grouping is by functionThe area tabs are the owner’s functions (liabilities and ALM, investing, funding, liquidity and collateral, operations and custody, control and regulation) and the product tabs under each are the flows. The facts table lists every flow with the same five columns. The flags open the same cycle for a US life insurer, a Canadian pension fund and a Dutch pension fund, where the liabilities, the regimes and the markets differ.
A flow can be read two ways: scroll the diagram and hover for detail, or press Walk through the steps above any diagram to follow it one step at a time, with the detail in a card. The arrow keys move forward and back.

Every diagram on this page is one turn of this cycle: the liabilities come in and are valued, the board sets the policy, the owner allocates and decides, the managers and the desks execute through the dealers, the assets settle at the custodian, and the books, the capital and the reporting follow. What the UK version shows is a life insurer whose growth is other people’s pension promises: the bulk annuities it writes for the schemes, the matching adjustment portfolio of private credit and gilts that pays them, the longevity and the funded reinsurance that share the risk, the LDI business it runs for the schemes that have not yet bought out, the collateral and the gilt market under stress, and the PRA’s Solvency UK, the FCA’s conduct rules and the Pensions Regulator around it.
The flows, 16 of them
Each card opens its diagram. The tabs at the top do the same; the search box finds a flow by name, rule, report or keyword.
Who decides each flow, who executes it, where the assets settle and sit, what capital it takes, who it is reported to
The same five questions for every flow: who decides it, who executes it with the owner, where the assets settle and sit, what capital it takes and how it is accounted, and who it is reported to. The answers are what make an asset owner: liabilities that set the purpose, a board and an actuary that set the frame, managers and dealers that execute, a custodian that holds, and the PRA, the FCA and the Pensions Regulator reading the capital and the reports.

Glossary
The terms that come back on every diagram. Every pill in the diagrams also shows its definition on hover.
Liabilities and ALM
Solvency UK: The UK’s prudential regime for insurers since the reforms of 2023 and 2024 (the onshored Solvency II with the risk margin cut, the matching adjustment reformed and the reporting reduced), set in the PRA’s rulebook: the best estimate liabilities, the risk margin, the SCR and the MCR, the own funds, the ORSA and the reporting.
Best estimate liabilities: The probability-weighted present value of the future cash flows of the insurance obligations under Solvency UK, discounted at the risk-free rate (plus the matching adjustment for the eligible annuities); with the risk margin, the technical provisions.
Risk margin: The amount added to the best estimate liabilities under Solvency UK so that the technical provisions equal what another insurer would require to take them on, computed as a cost of capital (4% since the 2023 reform, with a tapering for the long-dated liabilities) on the projected non-hedgeable SCR.
SCR: The solvency capital requirement: the own funds an insurer must hold to withstand a one-in-200-year loss over a year, computed with the standard formula or an approved internal model; the solvency ratio is the own funds over the SCR.
Bulk annuity: An insurance policy covering the pensions of a group of members of a defined benefit scheme, bought by the trustees with a single premium; a buy-in when the trustees hold it as an asset of the scheme, a buy-out when it is replaced by individual policies and the scheme is wound up.
Buy-in: A bulk annuity policy held by the scheme’s trustees as an asset that pays the scheme the pensions of the insured members; the scheme and the sponsor’s obligation continue, and the policy matches the liability it covers.
Buy-out: The conversion of a scheme’s liabilities into individual annuity policies issued by the insurer to each member, after which the trustees wind up the scheme and the sponsor’s obligation ends; the members’ pensions are then protected by the FSCS on the insurer.
Price lock: The mechanism that ties a bulk annuity premium to the value of the assets the scheme will transfer (the gilts and the credit) from the lock date to the transfer, so the market moves change the premium and the assets together and the trustees’ funding position is protected.
In-specie transfer: The payment of a premium or a subscription in securities rather than cash: the scheme’s gilts transferred free of payment through CREST to the insurer’s custody account at their value on the transfer date.
Data cleanse: The work after a buy-in to confirm the members, their benefits and their spouses against the scheme’s records, with the premium trued up for the differences before the buy-out; usually 12 to 24 months.
Benefit specification: The document setting out the pensions the insurer will pay: the amounts, the indexation in payment and in deferment, the spouses’ and the dependants’ pensions, the options, the GMP rules; the basis of the bulk annuity contract.
GMP equalization: The adjustment of the pensions of the members with a guaranteed minimum pension (from the contracted-out years before 1997) to remove the differences between men and women, required by the 2018 and 2020 Lloyds Banking Group judgments; a step every scheme completes before a buy-out.
New business strain: The capital an insurer uses when it writes a policy: the SCR and the risk margin set up at once, less the margin in the premium; financed by the capital the existing book generates.
Pension Protection Fund: The UK statutory fund that pays compensation to the members of a defined benefit scheme whose employer becomes insolvent with the scheme underfunded, financed by a levy on the schemes; a buy-out moves the members to the FSCS cover on the insurer.
Pensions Regulator: TPR, the UK regulator of the work-based pension schemes: the defined benefit funding code, the trustees’ duties, the guidance on the buy-ins, the LDI and the investment, the auto-enrollment duties of the employers.
Funded reinsurance: A reinsurance in which the reinsurer takes a share of the annuity liabilities and the assets backing them, paid with the premium, under a collateral arrangement; it frees the insurer’s capital and lets the reinsurer earn the spread, and since 2023 is the subject of the PRA’s particular scrutiny.
Matching adjustment: The adjustment under Solvency UK that adds to the risk-free rate used to discount the eligible annuities the spread an insurer earns on a portfolio of matching assets above the fundamental spread, so long-dated credit held to maturity reduces the best estimate liabilities and frees capital.
MA portfolio: The ring-fenced portfolio of assets assigned to the eligible liabilities under the PRA’s matching adjustment permission, managed separately, matched by cash flow and subject to the trading restrictions and the matching tests.
Fundamental spread: The part of an asset’s spread the PRA treats as compensation for the expected credit losses and the downgrade risk, published by asset class, currency, duration and credit quality step (and interpolated by notch since 2024); the matching adjustment is the spread above it.
Highly predictable cash flows: The cash flows the 2024 reforms admit in the MA portfolio beside the fixed ones: variable only within contractual bounds of timing and amount (the construction loans with a flexible drawdown, some callable debt), with their matching adjustment capped at 10% of the portfolio’s total MA and additional matching tests.
Matching tests: The tests that the asset cash flows of the MA portfolio cover the liability cash flows year by year within the PRA’s limits, with the additional reinvestment and liquidity tests for the highly predictable assets since 2024; a breach must be corrected by rebalancing.
Internal credit rating: The rating an insurer’s credit team assigns to an asset without an external rating, on a notched basis and of a standard comparable to the agencies’, validated with independent external assurance; it sets the credit quality step and so the fundamental spread of the asset in the MA portfolio.
MA attestation: The yearly statement since the year-end 2024 by the senior manager responsible for the financial information that the fundamental spread used reflects compensation for all the retained risks and the matching adjustment is well supported by the assets, with an out-of-cycle attestation after a material change.
MAIA: The matching adjustment investment accelerator (PS17/25, in force October 27, 2025): a firm with an MA permission may include self-assessed eligible assets with new features up to the lower of 5% of its best estimate liabilities and GBP 2,000,000,000, claim the MA at once and regularize them through a full application within 24 months.
MALIR: The matching adjustment asset and liability information return, filed with the PRA once a year for each MA portfolio, 130 business days after the year-end: the assets, their cash flows and ratings, the liabilities and the matching.
Lifetime mortgage: An equity release loan to a homeowner over 55 with the interest rolled up and the loan repaid from the sale of the home when the borrower dies or moves into care, with a no-negative-equity guarantee; written by the retail businesses of the annuity insurers and restructured into fixed notes for the MA portfolio.
No-negative-equity guarantee: The guarantee in a lifetime mortgage that the amount repaid never exceeds the value of the home, a put option on the house price the lender writes; valued in the PRA’s effective value test.
Effective value test: The PRA’s test that the restructured lifetime mortgage notes in an MA portfolio are not valued above the mortgages behind them less the value of the no-negative-equity guarantee on prudent house price assumptions.
Restructured asset: An asset placed in a special purpose vehicle that issues notes with fixed cash flows (the senior tranche held in the MA portfolio, the junior outside), so an asset with uncertain cash flows can back the matched annuities.
Longevity swap: A contract in which the insurer or the scheme pays a fixed series of expected pensions plus a fee and receives the pensions actually paid to the members alive, transferring the risk that they live longer than expected; written as a reinsurance treaty for an insurer.
CMI model: The Continuous Mortality Investigation’s projection model, updated each year by the actuarial profession, which turns the mortality data of England and Wales into the improvement rates the insurers and the schemes use, with each firm choosing the long-term rate and the parameters.
Recapture: The insurer’s right under a reinsurance treaty to take back the reinsured risk (and the assets in a funded deal) on defined triggers such as the reinsurer’s downgrade or default, with the termination amount and the collateral settling it.
Bermuda Monetary Authority: The regulator of the Bermudian insurers and reinsurers under a regime recognized as equivalent by the EU and the UK, the home of many of the reinsurers taking the longevity and the funded reinsurance of the UK and the US annuity writers.
IFRS 17: The international insurance contracts standard since 2023: the contracts measured at the fulfillment cash flows (the present value of the future cash flows with a risk adjustment) plus the contractual service margin, the unearned profit released over the coverage; the reinsurance held measured apart.
Contractual service margin: Under IFRS 17 the unearned profit of a group of insurance contracts at inception, released into the income statement over the coverage period; for a bulk annuity, the profit the insurer reports year by year over the life of the pensions.
QRT: The quantitative reporting templates an insurer files with the PRA quarterly and yearly under Solvency UK: the balance sheet, the own funds, the SCR, the assets line by line, the technical provisions.
SFCR: The solvency and financial condition report an insurer publishes yearly under Solvency UK: the business, the governance, the risk profile, the valuation, the capital management, with the quantitative templates.
Investing
Illiquidity premium: The spread a private asset earns above a public bond of the same rating and duration as the price of holding it without a market; an annuity writer whose liabilities cannot be surrendered can hold the asset to maturity and earn it.
Private placement: A bond or a loan sold directly to a few institutional investors under a note purchase agreement, with covenants and an agent; the UK and the US insurers are its main buyers, the issuers the utilities, the infrastructure and the mid-sized companies.
Infrastructure debt: The loans and the bonds of the infrastructure projects and the regulated companies (the transport, the utilities, the renewable generation, the social infrastructure), long-dated with stable cash flows; a core asset of the matching adjustment portfolios.
Housing association: A not-for-profit provider of social housing in England, regulated by the Regulator of Social Housing, which borrows long-dated fixed-rate and index-linked money from the banks, the bond markets and the insurers.
Make-whole: The prepayment clause that compensates the lender for the lost interest if the borrower repays early (the present value of the remaining payments at a government bond yield plus a spread), so the asset’s cash flows are fixed in substance.
Hedge ratio: The share of a pension scheme’s liability sensitivity to the interest rates and the inflation that its assets hedge, measured on the trustees’ funding basis; a 90% ratio keeps the funding level stable as the rates move.
Pooled LDI fund: An LDI fund shared by several smaller pension schemes, with a set leverage and a collateral waterfall that calls each scheme for cash in a stress; the most exposed structure in September 2022.
Segregated mandate: A mandate in which the manager runs a portfolio in the client’s own name and accounts under an IMA, the larger schemes’ route into LDI with their own leverage and collateral rules.
Collateral waterfall: The order in which an LDI fund meets its margin calls: its cash and money market funds, then its unencumbered gilts, then a call on the trustees for cash, and finally a cut in the leverage or the hedge if the call is not met.
Resilience standard: The minimum resilience of the leveraged LDI funds since 2023: a buffer to withstand at least a 250 basis point rise in the gilt yields, with an operational buffer on top, set by the Financial Policy Committee’s recommendation and applied by the Pensions Regulator and the FCA.
Financial Policy Committee: The Bank of England’s committee for financial stability, which identifies the systemic risks and makes recommendations to the regulators; its March 2023 recommendation set the LDI resilience standard.
Investment consultant: The adviser who helps the pension scheme trustees set the investment strategy, the hedge ratio and the manager choices, regulated by the FCA for the investment advice and subject to the CMA’s 2019 order on the trustees’ objectives for them.
Gilt repo: A repurchase agreement on gilts: the LDI fund sells gilts and agrees to buy them back, borrowing cash to buy more gilts; documented under the GMRA or sponsored into LCH RepoClear, with daily margin.
GMRA: The Global Master Repurchase Agreement, the standard master agreement for repos in Europe and the UK, with its annexes for the gilts and the margin.
Pension fund clearing exemption: The exemption of the pension scheme arrangements from the clearing obligation under UK EMIR, extended several times and made indefinite in 2025 on the cost of variation margin in cash and the liquidity risk in a stress.
IMA: The investment management agreement between an asset owner and a manager: the mandate, the guidelines and the limits, the benchmark, the fee, the reporting, the termination.
With-profits fund: A fund in which the policyholders share the profits of the business through bonuses that smooth the investment returns, ring-fenced from the shareholders’ funds; most UK with-profits funds are closed and in run-off.
Asset share: The accumulated premiums of a with-profits policy less the charges, with the investment return earned on them; the basis for the bonuses and the payout at maturity or surrender.
Regular and final bonuses: The bonuses of a with-profits policy: the regular bonuses added each year and guaranteed once added, and the final bonus paid at maturity or death to bring the payout toward the asset share.
Market value reduction: The reduction a with-profits fund applies to a policyholder leaving early when the asset share is below the value of the policy with its bonuses, so the leavers do not take more than their share.
Estate: The surplus of a with-profits fund above the asset shares of its policies, built up over the years and distributed to the remaining policyholders as the fund runs off.
PPFM: The Principles and Practices of Financial Management: the published rules of a with-profits fund on the bonuses, the smoothing, the investment strategy, the charges and the estate, which the firm must follow under the FCA’s rules.
With-profits committee: The committee, independent of the management, that advises the board on the fair treatment of the with-profits policyholders and reports to them each year; with the with-profits actuary, the fund’s governance under COBS 20.
90:10 split: The usual division of the distributed profits of a UK with-profits fund: 90% to the policyholders through the bonuses and up to 10% to the shareholders, so the shareholders take at most one ninth of the cost of the bonuses.
Unit-linked: A policy whose value is linked to the units of investment funds, priced daily; the policyholder bears the investment risk and the insurer earns the charges; the form of most workplace pensions sold by the insurers.
Default fund: The fund a workplace pension member is invested in without making a choice, usually a lifestyle or target date fund that derisks toward the retirement date; where most members’ money sits.
Automatic enrollment: The duty of UK employers since 2012 to enroll their eligible workers into a qualifying workplace pension with minimum contributions from the employer and the worker, who may opt out; the source of most new workplace pension members.
Charge cap: The cap of 0.75% a year on the charges of the default funds of the qualifying workplace pension schemes, since 2015.

Liabilities and ALM›Bulk Annuities
Bulk Annuity Writing: From the Scheme’s Request for Quotation to the Buy-In, the Premium in Specie and the Buy-Out
The insurer’s side of a defined benefit scheme’s buy-in: the adviser’s request for quotation with the member data, the pricing on the longevity basis and the matching adjustment spread of the assets the premium will buy, the reinsurance quotes, the pricing committee, the exclusivity, the policy signed with the price lock, the premium paid in gilts through CREST and in cash, the gilts switched into credit in the MA portfolio, the pensions paid to the scheme, the data cleanse and the buy-out with the individual policies and the wind-up.

A bulk annuity turns a pension scheme’s promises into an insurer’s liabilities: the scheme pays with its gilts, the insurer moves them into credit under the matching adjustment, reinsures most of the longevity, and pays the pensions for the next fifty years.
The market: the UK insurers wrote GBP 49,100,000,000 of bulk annuities in 2023 and GBP 47,700,000,000 in 2024 across about 300 transactions, with over GBP 40,000,000,000 expected for 2025 and 11 insurers quoting (Aon, LCP); the long-established writers compete with the entrants of the last few years, some owned by private equity or overseas groups; the smaller schemes are served by streamlined processes; the run-on of a well-funded scheme under the 2026 surplus rules and the superfunds are the alternatives the trustees now weigh.
The buy-in against the buy-out: the buy-in is an investment of the scheme (a policy the trustees hold, matching the pensions of the insured members) and the scheme continues; the buy-out replaces the scheme with individual policies and ends it, with the members’ pensions protected by the FSCS on the insurer instead of the Pension Protection Fund on the scheme; most transactions start as a buy-in and convert after the data cleanse.
The pricing: the competition is on the assets as much as on the longevity, since the spread the insurer expects to earn on the private credit it will buy, net of the fundamental spread, lowers the price it can quote; the reinsurance cost, the capital (the SCR and the risk margin under Solvency UK, the new business strain financed by the capital the back book generates) and the target return set the rest; the price lock removes the market risk between the signing and the transfer.
The PRA’s attention: the growth of the market concentrates long-dated credit and counterparty risk in a few insurers, so the PRA watches the funded reinsurance (the reinsurer taking the assets as well as the longevity), the private assets and the internal ratings in the MA portfolios, and tests the annuity writers in its life insurance stress tests; the trustees’ side is governed by the Pensions Regulator’s guidance and the trustees’ own advisers.
Liabilities and ALM›Matching Adjustment
The Matching Adjustment Portfolio: the Permission, the Cash Flows That Match, the Fundamental Spread, the Tests and the Attestation
The Solvency UK matching adjustment seen from the insurer: the eligible annuities and the ring-fenced MA portfolio, the PRA’s permission and the 2025 investment accelerator, the assets bought for their fixed or highly predictable cash flows, the restructuring of the lifetime mortgages and the callable loans through SPVs, the settlement into the designated accounts, the MA calculation as the spread over the risk-free rate less the fundamental spread, the internal ratings, the matching tests, the senior manager’s attestation and the MALIR.
Worked example, illustrative:the portfolio GBP 100,000,000,000: gilts, corporate bonds, private credit, restructured lifetime mortgage notesthe permission the PRA’s MA permission; the MA investment accelerator since October 2025the eligibility fixed cash flows, or highly predictable ones with their MA capped at 10%; a ratingthe calculation the spread over the risk-free rate less the fundamental spread, notched; added to the discount ratethe controls the matching tests each quarter; the trading restrictions; the yearly attestationthe reporting the MALIR yearly, the QRTs and the SFCR to the PRA

The matching adjustment turns a credit spread into capital: an insurer that holds assets to maturity against annuities it cannot lose to surrenders may discount those annuities at the risk-free rate plus the spread it earns, less what the PRA says the credit risk costs. The rest of the flow is the rules that keep it honest.
The 2024 reforms (PS10/24, in force June 30, 2024): the assets with highly predictable cash flows admitted with their MA capped at 10% of the total, the sub-investment grade assets no longer capped, the fundamental spread interpolated by notch, the senior manager’s attestation, new matching tests for the highly predictable assets, the in-payment income protection and the with-profits annuities admitted, and a six-month target for the applications; the MA asset and liability information return yearly.
The MA investment accelerator (PS17/25, in force October 27, 2025): a firm with an MA permission may hold self-assessed eligible assets with features its permission does not cover, up to the lower of 5% of its best estimate liabilities and GBP 2,000,000,000 (measured on nominal amounts including the commitments), claim the MA at once and bring them under a full application within 24 months, with a board-approved policy, a contingency plan for each asset and a yearly use report.
The fundamental spread: the PRA publishes it by asset class, currency, duration and credit quality step as the expected loss plus the cost of the downgrade risk (with a floor at a share of the long-term average spread); the matching adjustment is the asset spread above it, so a long private credit asset with an illiquidity premium earns a larger MA than a public bond of the same rating; the internal ratings of the unrated assets, validated externally, decide the step.
Restructuring: the lifetime mortgages (the equity release loans the retail business writes) have uncertain cash flows (the repayment when the borrower dies or moves into care) and a no-negative-equity guarantee, so they enter the MA portfolio through an SPV that issues fixed senior notes; the PRA’s effective value test checks that the notes’ value does not exceed the value of the mortgages less the guarantee; the same technique converts other assets the insurer wants to hold.
Liabilities and ALM›Longevity Reinsurance
Longevity Reinsurance: the Swap at the Point of Sale, the Monthly Net Settlement, the Collateral and the Capital Relief
The longevity risk of the annuity book passed to the global reinsurers: the quote with each bulk annuity, the reinsurer’s diversification against its mortality business, the treaty with its fixed leg of expected pensions and floating leg of actual pensions, the monthly net settlement by CHAPS, the collateral posted to a custodian, the board’s limits on the reinsurers, the capital relief under Solvency UK, the reporting and the PRA’s review of the risk transfer, and the IFRS 17 accounting of the reinsurance held.
Worked example, illustrative:the treaty a longevity swap in reinsurance form on 80% of the pensioners of each new deal, illustrativethe legs the fixed leg of expected pensions plus a fee; the floating leg of actual pensions; a monthly netthe reinsurers the global reinsurers in Europe, the US and Bermuda; the retrocession to the capital marketsthe collateral gilts and cash in a custody or trust account, revalued monthly or quarterlythe capital the longevity SCR and the risk margin reduced; the counterparty default risk addedthe accounting IFRS 17: the reinsurance held with its own contractual service margin

Jump to11 steps, hover or click any of them
Longevity is the one risk an annuity writer cannot hedge in the market, so it is shared with the reinsurers, for whom it offsets the risk of their life protection business. The insurer pays a fee for decades, keeps the assets and the spread, and holds collateral against the day a reinsurer cannot pay.
The forms: a longevity swap (the insurer keeps the assets and swaps the expected pensions for the actual ones) is the usual form for the annuity writers, written as a reinsurance treaty; a pension scheme can also do a longevity swap directly through an insurer acting as the intermediary (the pass-through structure), before or instead of a buy-in; the funded reinsurance transfers the assets with the longevity and is covered in the funding group.
The pricing: the reinsurers compete on their long-term improvement assumption, their capital cost and the diversification they get; the CMI model (the Continuous Mortality Investigation’s projection model, updated each year) gives the industry a common frame with each firm’s own parameters; the experience since the pandemic (the excess deaths of 2020 to 2022 and the slower improvements) has been folded into the bases gradually, with the weight the model gives to each year of data.
The counterparty risk: a few global reinsurers carry most of the UK longevity, so the insurer’s exposure to each is large; the collateral, the downgrade triggers and the recapture rights limit it, and the PRA tests the collateral arrangements and the concentration in its supervision; a Bermudian reinsurer is supervised by the Bermuda Monetary Authority under a regime the UK and the EU recognize as equivalent.
The capital relief: the longevity SCR is one of the largest parts of an annuity writer’s capital, and the risk margin under Solvency UK (since the 2023 reform on a 4% cost of capital with a tapering for the long-dated liabilities) follows it; reinsuring 80% of the longevity at the point of sale lowers the new business strain of each deal, so the reinsurance capacity is a constraint on the volume of bulk annuities the market can write.
Investing›MA Private Credit
Private Credit for the Matching Adjustment Portfolio: the Pipeline, the Origination, the Internal Rating and the Closing
The private credit the in-house asset manager originates for the annuity fund: the pipeline set by the bulk annuity premiums, the origination in infrastructure, housing and real estate, the credit work and the structuring for the MA eligibility with the notched internal rating, the credit committee, the documents and the closing with the agents, the funding and the custody, the quarterly monitoring, and the PRA’s reviews beside the productive finance agenda.
Worked example, illustrative:the pipeline about a third of GBP 8,000,000,000 of premiums a year into private credit, illustrativethe assets infrastructure debt, housing association bonds, real estate loans, private placements, ground rentsthe spread 150 to 250 basis points over gilts; an illiquidity premium of 50 to 100 basis points, illustrativethe eligibility fixed or highly predictable cash flows; make-wholes; a notched internal ratingthe closing English law loan and note agreements; the agents; the drawdowns by CHAPS; Euroclear and the registrarsthe control the credit committee; the quarterly monitoring; the PRA’s reviews of the internal ratings

A UK annuity writer is now one of the largest lenders to UK infrastructure and housing: the premiums arrive with each bulk annuity and the in-house manager must place them in long, fixed cash flows that earn an illiquidity premium and survive the PRA’s review of the ratings.
The asset classes: the infrastructure debt (the regulated utilities, the transport, the renewable generation under contracts for difference, the social infrastructure), the housing associations (long fixed-rate and index-linked bonds and loans, regulated by the social housing regulator), the commercial real estate loans and the long-lease and income strip structures, the private placements of the UK and US companies, the lifetime mortgages from the retail business (restructured, see Matching Adjustment); each is chosen for its cash flows as much as its spread.
The illiquidity premium: the private assets earn a spread above a public bond of the same rating and duration as the price of holding them to maturity without a market; the insurer can hold them because its annuities cannot be surrendered, and the matching adjustment recognizes the spread above the fundamental spread as capital, so the premium is passed partly to the schemes through the bulk annuity prices.
The internal ratings: the unrated private assets need an internal rating comparable to the agencies’ and validated externally, since the rating sets the fundamental spread and so the MA; the PRA’s reviews of the internal ratings and of the private assets in the MA portfolios are the main supervisory risk to the model, and a downgrade of a large position cuts the MA at once.
The productive finance agenda: the government presented the Solvency UK reforms as a way to channel the insurers’ capital into UK infrastructure, housing and clean energy, and the large annuity writers publish their UK investment figures; the workplace pension providers made their own commitments on private markets in the 2025 Mansion House Accord (see With-Profits and Unit-Linked).
LDI for the Pension Schemes: the Hedge Ratio, the Leverage, the Collateral Waterfall, September 2022 and the Resilience Standard
The LDI business the in-house asset manager runs for the defined benefit schemes that have not bought out: the hedge ratio the trustees set with their consultant, the pooled and the segregated funds, the leverage from the gilt repo and the swaps, the clearing at LCH and the settlement in CREST, the collateral waterfall and the calls on the trustees, the margin spiral of September 2022 and the Bank of England’s purchases, the 250 basis point resilience standard, and the scheme’s path from the LDI fund to the bulk annuity.

LDI let the schemes hedge their liabilities while keeping assets for growth, and the leverage that made it possible turned a rate rise into a cash call. The same group that runs the hedge is waiting to take the scheme at buy-out.
The hedge ratio: a scheme’s liabilities rise in value when the long gilt yields fall and when the inflation expectations rise; the LDI fund holds gilts and swaps whose value moves the same way, measured against the liabilities on the trustees’ funding basis; a 90% hedge ratio leaves the funding level stable whatever the rates do, and the leverage lets a scheme hedge more than the assets it puts into the fund.
September 2022: the long gilt yields rose faster than at any time in decades after the fiscal statement of September 23; the LDI funds’ collateral calls outran the trustees’ ability to raise cash, the forced gilt sales fed the rise, and the Bank of England bought long-dated gilts from September 28 to October 14 (about GBP 19,300,000,000) to stop the spiral; the funds rebuilt their buffers through calls on the trustees and cuts in the hedges.
The resilience standard: the Financial Policy Committee recommended in March 2023 that the LDI funds withstand at least a 250 basis point rise in the gilt yields (the minimum resilience) plus an operational buffer, applied by the Pensions Regulator’s guidance to the trustees and the FCA’s to the managers, with the collateral waterfalls tested and the buffers reported; the leverage in the system fell and the funds hold more cash.
The clearing exemption: the UK EMIR exemption of the pension schemes from the clearing obligation was made permanent in 2025, the government citing the cost of variation margin in cash and the liquidity risk in a stress; the schemes still clear much of their swap book through the clearing brokers by choice, with the sponsored repo at LCH as a source of liquidity for the margin.

The funds the policyholders own: the closed with-profits fund with its asset shares, smoothed bonuses, estate and 90:10 split, the bonus declaration within the PPFM reviewed by the with-profits committee, the fund’s investment mandate; the workplace pension contributions into the default fund, the daily unit pricing within the charge cap, the fund links to the in-house and external managers and the Mansion House private markets aim, the dealing and the custody, the Consumer Duty and the Value for Money framework, and the statements and the retirement options.

In these funds the money is the policyholders’, not the insurer’s: the with-profits fund pays out its profits as bonuses under published principles, and the unit-linked funds pass the market through a daily price. The insurer earns the charges and the shareholders’ share, and answers to the conduct regulator for the value.
The with-profits fund: the policyholders’ premiums are pooled and invested in a mix of real and fixed income assets, the returns smoothed through the regular bonuses added each year and the final bonus at maturity or death, with a market value reduction on early exits when the asset share is below the guaranteed value; most UK with-profits funds are closed to new business and run off, with the estate distributed to the remaining policyholders.
The governance: the PPFM is the fund’s published rulebook, the with-profits actuary advises on the bonuses and the fairness, and the with-profits committee (or an adviser for a small fund), independent of the management, reports to the policyholders; the FCA’s rules on the with-profits business (COBS 20) govern the fairness, and the PRA restricts the use of the fund’s capital to the fund.
The workplace pensions: the employers enroll their workers automatically into a qualifying scheme with minimum contributions, and most members stay in the default fund; the providers compete on the charges (within the 0.75% cap on the default) and the governance, and the government’s Mansion House Accord of 2025 and the pensions reforms push the default funds toward private markets and larger scale.
The Value for Money framework: proposed by the FCA, the Pensions Regulator and the government for the defined contribution workplace schemes, it would compare each default arrangement’s performance, costs and service against a commercial comparator group and rate it on four grades, with the weakest closed to new business and moved; the 2026 consultation (CP26/1) set the first assessments for 2028, and the Pension Schemes Act extends it to the trust-based schemes.
The Gilt and Credit Desk: the Auctions Through the GEMMs, the Secondary Market, the Settlement in CREST and the Stock Lending
The in-house asset manager’s public market desks for the annuity fund and the LDI funds: the orders and their allocation between the funds, the bids in the gilt auctions through the GEMMs and the DMO’s syndications, the secondary trading of gilts and credit on the platforms and by phone, the best execution, the settlement at T+1 in CREST and in the international CSDs, the stock lending through the agent lender, the credit research feeding the internal ratings, and the reporting and market conduct rules.
Worked example, illustrative:the clients the annuity fund’s MA portfolio and the LDI funds; one desk, an allocation policythe primary the DMO’s auctions through the GEMMs; the syndications of the long and index-linked gilts; the corporate new issuesthe secondary gilts on Tradeweb and Bloomberg; credit on MarketAxess and Tradeweb; blocks by phonethe settlement gilts at T+1 in CREST; Eurobonds in Euroclear and Clearstream; T+1 from October 2027the lending the agent lender at the custodian; the MA limits; UK SFTRthe conduct best execution; the transaction reports through an ARM; UK MAR surveillance; the SMCR

A large UK annuity writer and its LDI business own a share of the long gilt market large enough to matter to the DMO; the desk that buys for them is a client of the GEMMs in the auctions, a counterparty of the dealers in the secondary, and a lender of the bonds it holds.
The gilt market: the DMO issues the conventional and the index-linked gilts through auctions (bid-price for the conventionals, uniform price for the linkers) and syndications for the long and the index-linked lines, with the GEMMs as the primary dealers that bid, make markets and have access to the DMO’s facilities; the pension schemes and the insurers hold most of the long end, so their demand shapes the DMO’s issuance plan.
The allocation between the funds: the annuity fund and the LDI funds may want the same gilts at the same time, so the manager’s order allocation policy sets how the aggregated orders and the auction allotments are shared, pro rata to the orders or by a predefined rule, recorded before execution and reviewed by compliance under the FCA’s conflicts rules.
The settlement: the gilts settle in CREST at T+1 in central bank money, through the CREST members’ settlement banks and the Bank of England’s RTGS; the UK’s move to T+1 on October 11, 2027 brings the corporate bonds and the equities in line, and shortens the time to recall a lent bond before a sale.
The stock lending: the funds lend their bonds through the custodian’s agent lending program for a fee, against collateral with a margin and an indemnity from the agent; for the MA portfolio the lending must not break the matching or the eligibility, and the collateral reinvestment is kept short and high quality; the LDI funds’ gilts are often encumbered in the repo instead.
Funding, Liquidity and Collateral›Funded Reinsurance
Funded Reinsurance of an Annuity Block: the Treaty, the Premium in Assets, the Collateral Trust and the Recapture
Part of a bulk annuity block reinsured with a Bermuda reinsurer on a funded basis: the board’s limits under SS5/24, the treaty with the eligible collateral and the recapture triggers, the premium paid in gilts and bonds, the collateral posted into a UK trust with the haircuts, the reinsurer’s reinvestment in the private credit of its affiliated manager, the collateral tests and the solvency watch, the capital released, the PRA’s supervisory statement and the recapture scenario of the 2025 stress test, and the recapture itself.
Worked example, illustrative:the block GBP 3,000,000,000 buy-in; 40% reinsured on a funded basis; the asset and the longevity risk transferredthe treaty a quota share; the premium paid in assets; the recapture triggers on the solvency, the rating and the collateralthe collateral a UK security trust; eligible assets after haircuts; 110% of the reserve, illustrativethe limits per counterparty, for the correlated counterparties and in aggregate under SS5/24the capital the SCR on the reinsured share replaced by a counterparty charge; capital for new buy-insthe supervision PS13/24 and SS5/24 (July 2024); the recapture scenario of LIST 2025

Funded reinsurance trades the asset and the longevity risk of an annuity block for a counterparty exposure offshore. Its value depends on what the collateral trust would hold on the day the reinsurer failed, and that is where the limits, the haircuts and the recapture plan come in.
Funded against unfunded: a longevity swap or a longevity reinsurance treaty transfers the longevity risk alone, with the assets staying at the insurer and a collateral exchange on the net cash flows; funded reinsurance transfers the assets too, so the insurer’s exposure on a default is the whole reinsured reserve less what the collateral covers; the funded deals grew with the Bermuda reinsurers backed by the alternative asset managers after 2020.
The PRA’s concerns: the concentration of the market on a few reinsurers with correlated assets (the private credit originated by their affiliated managers), the reliance on a recapture in a stress when many cedants might recapture at once, the valuation and the liquidity of the collateral, and the regulatory arbitrage between the regimes; SS5/24 asked for limits measured on the loss after recapture, risk-based haircuts and over-collateralization, and a board-owned recapture plan, and the PRA said it could restrict the arrangements or adjust the SCR if the exposures kept growing.
The Bermuda side: the reinsurer is supervised by the Bermuda Monetary Authority under a regime the EU found equivalent to Solvency II, with the enhanced capital requirement under the BSCR; the 2024 changes to the Bermuda regime tightened the asset and the liquidity rules for the long-term reinsurers; the reinsurer’s solvency ratio is a recapture trigger in the treaty.
Accounting: under IFRS 17 the treaty is a reinsurance contract held, measured with its own fulfilment cash flows and contractual service margin (a gain or a cost of reinsurance spread over the coverage), and the collateral in the trust is not the insurer’s asset until a recapture; under Solvency UK the reinsurance recoverable sits on the balance sheet net of the expected default, with the counterparty risk in the SCR.
Collateral and Liquidity of the Annuity Book: the Swaps, the Daily Margin, the Gilt Repo and the 2022 Stress
The annuity writer’s liquidity seen through its hedges: the SONIA, the inflation and the cross-currency swaps that close the gaps of the matching portfolio, the liquidity buffer the board sets for a 250 basis point shock, the swaps cleared at LCH and the bilateral ones under credit support annexes, the daily variation margin in cash, the gilt repo that raises it, the collateral moved and optimized without breaking the matching adjustment, the September 2022 gilt stress and the Bank of England’s contingent repo facility, and the PRA’s liquidity expectations.
Worked example, illustrative:the hedges GBP 60,000,000,000 of SONIA swaps and GBP 20,000,000,000 of RPI and CPI swaps; cross-currency swaps on the MA credit, illustrativethe clearing LCH SwapClear through the clearing brokers; the bilateral swaps under ISDAs and credit support annexesthe buffer cash, money market funds and unencumbered gilts for a 250bp rise, illustrativethe cash gilt repo bilateral, tri-party or at LCH RepoClear; committed linesthe stress September 2022: the long gilts up more than 100bp; the Bank’s purchases from September 28 to October 14the backstop the Bank of England’s Contingent NBFI Repo Facility; the PRA’s SS5/19

The annuities pay over decades but the hedges settle every morning. The liquidity of an annuity writer is the liquidity of its collateral, and the buffer, the repo lines and the Bank’s facility are sized against the day the long rates jump.
Why the insurer pays margin when rates rise: an annuity writer hedging its liabilities receives the fixed rate (and the inflation) on its swaps, so a rise in the long rates lowers the value of the swaps and calls variation margin, while the liabilities fall by about as much; the solvency is protected and the liquidity is drawn, the same mechanics that hit the LDI funds in 2022 with far more leverage.
The matching adjustment and the collateral: the MA portfolio must be identified and managed separately, its cash flows must match the liabilities, and its assets cannot be used for other purposes without breaking the matching; the insurer keeps a pool of gilts and cash outside the MA portfolio for the margin, or tags the MA assets it can pledge within the matching tests.
The cross-currency swaps: the private credit in dollars and euros that the MA portfolio buys must be swapped into fixed sterling to be eligible, so the insurer runs a book of long-dated cross-currency swaps with the dealers whose margin moves with the exchange rates; a strong dollar calls collateral from the insurer, a liquidity cost of the MA’s sterling requirement.
Uncleared margin: the larger insurers are in scope of the initial margin requirement on their uncleared derivatives above the aggregate notional threshold, with the margin segregated at a third-party custodian on both sides; the clearing obligation of UK EMIR applies to the insurers as financial counterparties above the threshold, unlike the pension schemes, whose exemption from clearing ended in June 2023.
Funding, Liquidity and Collateral›Capital Issuance
Capital Instruments Under Solvency UK: a Tier 2 and a Restricted Tier 1 Issue, the PRA’s Tiering and the Call
The group’s subordinated capital seen from the treasury: the capital framework and the solvency target, the board’s plan, the notification to the PRA with the tiering terms (the deferral and the cancellation of coupons, the Restricted Tier 1 trigger), the EMTN drawdown with four joint lead managers, the bookbuilding, the settlement in the ICSDs, the call or the tender of the old Tier 2 with the PRA’s non-objection, and the own funds, the coupons and the ratings after the issue.
Worked example, illustrative:the target a Solvency UK coverage of 150% to 180%; own funds GBP 9,000,000,000, illustrativethe issue GBP 500,000,000 Tier 2 and GBP 500,000,000 Restricted Tier 1, illustrativethe terms Tier 2 dated ten years and more, callable after five; RT1 perpetual with a trigger at 75% of the SCRthe documents the EMTN program; the listing on the LSE; the UK prospectus regime from January 2026the settlement T+5 through Euroclear and Clearstream; the common safekeeperthe control the PRA’s non-objection to the call; the tier limits each quarter; the rating agencies’ equity credit

The subordinated notes of an insurer are written to the capital rules before they are written for the investors: the tier decides the terms, and the PRA decides the calls. They sit between the equity and the reinsurance in the funding of the bulk annuity growth.
The tiers: Solvency UK keeps the Solvency II tiers: Tier 1 unrestricted (the equity, the reconciliation reserve), Tier 1 restricted (the perpetual subordinated notes with the loss absorption), Tier 2 (the dated subordinated notes and the ancillary own funds), Tier 3 (the short-dated subordinated debt, the deferred tax assets); the limits apply to the eligible own funds covering the SCR (at least half Tier 1, the restricted part no more than a fifth of Tier 1) and the MCR (Tier 1 and Tier 2 only).
The calls: a call before the first five years only for a tax or a regulatory event, and any call or buyback subject to the PRA’s non-objection and to the replacement with capital of the same or a better quality unless the solvency is comfortably above the requirement; the market expects the first call to be exercised, so the PRA’s view of the solvency at that date is part of the note’s pricing.
The holding company: the notes are issued by the listed holding company and the proceeds lent or contributed to the life company as capital; the holding company’s own liquidity (the cash, the committed facility, the dividends up from the subsidiaries) pays the coupons and the dividend, and the rating agencies measure its leverage and its fixed charge cover.
Accounting: the Tier 2 notes are financial liabilities at amortized cost under IFRS 9; the Restricted Tier 1 notes, with discretionary coupons and no maturity, are usually equity instruments under IAS 32, with the coupons paid as distributions; the Solvency UK balance sheet values the subordinated debt without the insurer’s own credit spread changes.
Operations and Custody›Custody Operations
Custody Operations: the Segregated Accounts, Settlement, Income, the Reconciliations and the MA Data
The insurer’s portfolios at the global custodian: the separate accounts for the matching adjustment portfolio and the other funds, the trades instructed and settled in CREST and the ICSDs, the income and the corporate actions, the securities lending restricted for the MA assets, the daily three-way reconciliation, the MA tagging and the cash flow feed to the actuaries, and the PRA’s outsourcing and operational resilience rules on the custodian and the asset manager.
Worked example, illustrative:the accounts the MA portfolio ring-fenced; the non-MA, with-profits, unit-linked and shareholder fundsthe settlement CREST for the gilts and UK equities; Euroclear and Clearstream for the Eurobonds; T+1 from October 11, 2027the servicing the coupons, the redemptions, the corporate actions, the tax reclaimsthe lending through the custodian as agent with an indemnity; restricted for the MA assetsthe data the IBOR, the ABOR and the custodian reconciled daily; the MA cash flows to the actuariesthe rules SS2/21 on outsourcing; the operational resilience tolerances since March 2025

For an annuity writer the custodian holds the data as much as the securities: the matching adjustment needs every asset tagged and its cash flows known, and the regulator needs the insurer able to leave the custodian or the manager without losing that.
The matching adjustment and the custody: the MA portfolio must be identified, organized and managed separately from the insurer’s other business and cannot be used to cover losses elsewhere; separate custody accounts with the MA tag in the books make the ring-fence visible to the auditors and the PRA, and the asset-level cash flows feed the matching tests.
The private assets: the loans and the private placements of the MA portfolio settle outside the depositories through the agents and the lawyers, with their documents held by the custodian or a document custodian and their positions recorded in the custody statements; their valuations come from the valuation team and the independent valuers rather than from market prices.
The outsourcing rules: SS2/21 (in force since March 2022) applies to the material outsourcings and the third-party arrangements: the risk assessment, the contract terms, the business continuity and the exit plans, the notification to the PRA; the critical third parties regime of 2025 adds the direct oversight of the largest providers to the financial sector by the regulators.
Settlement discipline: the UK did not adopt the EU’s settlement discipline regime under the UK CSDR; CREST settles in central bank money through the Bank of England’s RTGS, and the UK move to T+1 for the securities settlement, set for October 11, 2027, is aligned with the EU’s date.
Operations and Custody›Annuity Payroll
The Annuity Payroll: the Buy-In Payments, the Buy-Out, PAYE, Bacs and the Mortality Checks
The pensions an annuity writer pays: the monthly payment to the trustees under a buy-in, the data cleanse and the buy-out that turn the members into the insurer’s policyholders, the monthly payroll with the increases, PAYE with the tax codes and the RTI returns, the payment through Bacs, the mortality screening and the existence checks, the member service and the bereavements, the Consumer Duty and the schemes’ regulator.

Writing a buy-in is a pricing decision; paying it is an operation that runs for forty years. The payroll, the tax and the mortality checks are where the scheme’s data quality becomes the insurer’s cost and the members’ experience.
Buy-in and buy-out: under a buy-in the policy is an asset of the scheme and the trustees remain responsible for the members, so the insurer pays the scheme; after the buy-out the members hold individual policies and the insurer pays them directly, takes on their administration and the scheme is wound up; the data cleanse between the two corrects the records and trues up the premium.
The increases: the pensions in payment increase each year by the scheme rules for each tranche of service (the limited price indexation of the RPI or the CPI capped at 5% or 2.5%, the fixed increases, none for the pre-1997 excess), which the insurer copies into its payroll; its inflation swaps hedge the indexed part.
The tax: pensions are taxed as earnings under PAYE; the insurer, as payer, applies the codes from HMRC and reports in real time like an employer; the lump sums and the trivial commutations at retirement follow the pensions tax rules (the tax-free amount within the lump sum allowance since April 2024).
Protection: the annuities of a UK insurer are covered in full by the Financial Services Compensation Scheme if the insurer fails, a stronger protection than the Pension Protection Fund gives the members of a scheme whose sponsor fails, which is part of the case for a buy-out.
Operations and Custody›Workplace Contributions
Workplace Pensions: Auto-Enrolment Contributions, the Units, the Transfers and the Dashboards
The insurer’s workplace pension business: the employer’s choice of the group personal pension or the master trust under the auto-enrolment duty, the monthly contribution schedule and the direct debit collection, the units allocated at the daily forward price, the default fund invested by the in-house manager with its private market sleeve, the transfers through the network, the connection to the pensions dashboards, the statements and the retirement options, and the Value for Money framework.

Workplace pensions are a volume business: small monthly contributions from thousands of employers, allocated to units and invested in a few default funds. The rules now push the market toward scale, private assets and comparable value.
Contract-based against trust-based: a group personal pension is a set of individual contracts between the members and the insurer, regulated by the FCA with an Independent Governance Committee; a master trust is a multi-employer trust with its own trustee board, authorized and supervised by the Pensions Regulator; the large insurers run both and move employers between them.
The unit-linked mechanics: the default fund is a unit-linked fund of the insurer (for the contract-based scheme) or the trust’s investment (for the master trust); the forward pricing, the box management of the units, the dilution levies and the pricing errors are the operational risks, and the unit price is the member’s only view of the investment.
The private market push: the Mansion House Compact of 2023 and the Accord of 2025 brought the larger providers to commit a share of their default funds to private markets; the long-term asset funds and the private market vehicles inside the unit-linked structure, the daily dealing of the default fund and the charge cap are the constraints.
The reforms under way: the Pension Schemes Act 2026 sets the minimum scale for the multi-employer default funds (the megafunds), the small pots consolidation, the decumulation defaults and the Value for Money framework; the pensions dashboards bring every pot into one view for the member.
Control and Regulation›Solvency Reporting
Solvency UK Reporting: the Balance Sheet, the SCR, the MA Attestation, the Templates and the SFCR
The insurer’s regulatory reporting cycle: the asset data from the manager and the custodian, the Solvency UK balance sheet with the matching adjustment, the reduced risk margin and the transitional, the SCR from the internal model, the board’s review and the senior manager’s MA attestation, the quarterly and annual templates to the PRA, the audit of the SFCR, its publication, the RSR and the ORSA, and the internal model changes.
Worked example, illustrative:the balance sheet best estimate at risk-free plus the MA; the risk margin at a 4% cost of capital; the TMTP to 2032the capital the SCR from the internal model; own funds by tier; a coverage of 170%, illustrativethe templates quarterly within five weeks; annual within fourteen weeks; through the Bank’s portalthe public the SFCR within fourteen weeks; the balance sheet and own funds auditedthe attestation the senior manager’s yearly MA attestation since the 2024 reformsthe model major changes approved by the PRA; minor changes reported quarterly

The Solvency UK books value the same insurer a second way, on the regulator’s discount rate and capital model. The reporting cycle runs from each bond’s data to the board, the PRA and the public, with a senior manager’s name on the matching adjustment.
The matching adjustment: the insurer discounts its annuity liabilities at the risk-free rate plus the spread its matched assets earn above the fundamental spread (the allowance for the default and the downgrade risk, set by the PRA by asset class, rating and duration), because it holds the assets to maturity; the 2024 reforms allowed the assets with highly predictable cash flows up to 10% of the MA benefit, notched the fundamental spread by rating, and added the attestation.
The risk margin: the market value margin a transferee would require to take on the non-hedgeable risks, computed as the cost of holding the future SCRs; the reform at December 31, 2023 lowered the cost of capital rate from 6% to 4% and added a tapering factor for the long-dated risks, which released capital for the annuity writers and reduced their reliance on the transitional measure.
The transitional measure on the technical provisions: the deduction phasing in the move from the old regime to Solvency II over sixteen years from 2016, recalculated every two years or on a material change, which runs off by the end of 2031; the insurers report their coverage with and without it.
Reporting reforms: Solvency UK removed a number of templates and reduced the frequency of others from the 2024 year end, introduced the UK-specific matching adjustment templates, and moved the reporting to the Bank of England’s data collection platform; the PRA’s templates remain close to the EU’s, which eases the comparison with the European insurers.
Control and Regulation›PRA Supervision
The PRA’s Supervision of an Annuity Writer: the SMCR, the Periodic Letter, the Thematic Reviews and LIST 2025
How the PRA supervises a large bulk annuity writer: the senior managers approved under the SMCR, the periodic summary meeting and the letter, the thematic reviews of the pricing, the private assets and the funded reinsurance, the life insurance stress test of 2025 with the first firm-level publication, the supervisory tools, the resolution planning and the Financial Policy Committee, and the FCA’s conduct supervision alongside.

The PRA supervises the people, the assets and the reinsurance of an annuity writer, and since 2025 it publishes how each one fares in its stress test. The trustees choosing an insurer for their members now read the regulator’s results.
The PRA’s approach: judgment-based and forward-looking, with the intensity set by the firm’s potential impact on the policyholders and the system; the largest annuity writers are in the top categories, with the dedicated supervisors, the specialists on the asset valuations and the models, and the yearly cycle of the periodic summary meeting.
LIST 2025: the PRA’s second life insurance stress test after 2022, designed with the bulk annuity market in mind; publishing the firm-level core results was new, intended to give the trustees and their advisers comparable information when they choose an insurer.
The senior managers: the SMCR gives the PRA and the FCA named individuals accountable for each area (the chief actuary for the technical provisions, the chief risk officer for the risk management, a named senior manager for the matching adjustment attestation), with the duty of responsibility that lets the regulators act against an individual who failed to take reasonable steps.
Resolution: the banks have a resolution regime since 2009; for the insurers the PRA relies on the solvent run-off, the transfers under Part VII of FSMA and the FSCS, and the Treasury’s proposed regime would give the Bank of England the powers (the transfer of the business, the write-down of the liabilities in the policyholders’ interest) to resolve a failing insurer.
Control and Regulation›IFRS 17 Results
IFRS 17 Results: the CSM on a Buy-In, the Close, the APMs, the Audit and the Dividend
The insurer’s financial reporting: a buy-in measured under IFRS 17 with its contractual service margin, its risk adjustment and its illiquidity premium, the half-year close with the CSM roll-forward, the results with the operating profit and the capital generation, the auditors’ review, the results on the RNS, the rating agencies, the annual report under the FCA’s rules and the FRC’s review, and the dividend within the capital framework.

IFRS 17 spreads the profit of an annuity over its life; Solvency UK charges its capital up front. An insurer’s results day reconciles the two, and its dividend follows the cash the capital releases.
The contractual service margin: the unearned profit of a group of insurance contracts, set at inception so that no gain is recognized on day one, accreted with interest, adjusted for the changes in the estimates of the future service, and released to the profit as the service is provided; for an annuity book the release follows the coverage units, the pensions expected to be paid.
The discount rate: IFRS 17 discounts the annuity liabilities at a rate reflecting their illiquidity (the bottom-up risk-free plus an illiquidity premium, or the top-down from the reference assets’ yields less their credit risk), which the UK insurers set close to, but not the same as, the Solvency UK matching adjustment; the difference shows in the reconciliation of the two balance sheets.
The alternative performance measures: the operating profit, the capital generation, the CSM and the new business profits are the measures the insurers manage to and the investors compare; the FCA’s rules and the ESMA guidance that the UK kept require them to be defined and reconciled to the IFRS figures.
Variable fee approach: the with-profits and the unit-linked contracts, where the policyholders share in a pool of underlying items, are measured under the variable fee approach, with the insurer’s share of the returns flowing through the CSM rather than the profit.
