The Investment Firms Prudential Regime changed what UK investment firms have to calculate, report and document — and it landed on finance functions that had largely been built for statutory reporting. The regime has applied since 1 January 2022, and most firms now have the returns going out. Fewer have someone who genuinely understands what sits behind them, and fewer still have that capability in more than one head. This guide is about the people rather than the rules: who actually builds MIFIDPRU returns and the ICARA, what skills the work requires, where firms are typically short, and how to test for the capability when hiring.
For the regime itself, the FCA’s IFPR pages and the MIFIDPRU sourcebook are the authoritative sources, and our guide to regulatory capital, ICARA and the IFPR covers the framework. This page assumes that ground and focuses on the hiring dimension.
What the work actually consists of
Four workstreams, and they demand different things from the person doing them.
Own funds and the capital calculation. Determining own funds by tier, applying deductions, and calculating the own funds requirement as the higher of the permanent minimum requirement (£75,000, £150,000 or £750,000 depending on permissions), the fixed overheads requirement (a quarter of relevant annual fixed expenditure) and, for firms that are not small and non-interconnected (SNI), the K-factor requirement. The mechanics are arithmetic; the judgement lies in what belongs in the fixed overheads calculation and how the K-factors are derived from the firm’s actual activity.
K-factor measurement. The activity-based metrics — assets under management, client money held, assets safeguarded and administered, client orders handled, and the risk-to-market and risk-to-firm factors where applicable. This is where finance meets operations, because the source data lives in systems finance does not own, and getting it out reliably each period is frequently the practical difficulty.
The regulatory returns. Submissions through RegData on the reporting calendar, with the reconciliation and evidence behind each. Our guide to RegData, COREP and FINREP covers the mechanics.
The ICARA process. The Internal Capital Adequacy and Risk Assessment: identifying harms, assessing whether own funds and liquid assets are adequate, wind-down planning, and documenting it all to a standard a supervisor would accept. This is the workstream that most often has no clear owner, because it sits across finance, risk and compliance — and it is the one the FCA looks at. The MIFIDPRU sourcebook sets out what the assessment must cover, and it must be reviewed at least annually and approved by the governing body.
The MIFIDPRU returns and what sits behind each
The candidate who has genuinely owned MIFIDPRU reporting can tell you what each return contains, where its numbers come from and how it ties to the others. The core items for most firms are below; further MIFIDPRU data items apply depending on size, activities and group structure, and the firm’s RegData reporting schedule is the reference.
| Return | What it covers | Frequency | Skill it tests |
|---|---|---|---|
| MIF001 | Own funds, own funds requirement and the own funds threshold requirement | Quarterly | Own funds tiering and deductions, fixed overheads judgement, K-factor totals |
| MIF002 | Liquidity — the basic liquid assets requirement and liquid assets held | Quarterly | Liquidity measurement and classification of core liquid assets |
| MIF003 | Monitoring metrics — the activity data from which K-factor requirements are derived (non-SNI firms) | Quarterly | Data extraction from operational systems and averaging |
| MIF007 | ICARA questionnaire — key figures from the firm’s ICARA | Annual | Consistency between the ICARA document, the model and the returns |
The FCA’s data quality review of MIFIDPRU reporting is a useful brief for any interviewer. It found MIF007 values that differed substantially from firms’ own ICARA documents, own funds threshold requirements reported below the own funds requirement, key fields such as the K-factor requirement left blank, figures in the wrong units (returns should be in sterling thousands), and data copied unchanged from one period to the next. Each is a skills and controls failure, not a misreading of the rules.
K-factor calculations: what the person must get right
For non-SNI firms, the K-factor requirement is the sum of the applicable K-factors, each calculated by applying a coefficient to a rolling average of the underlying metric. For the risk-to-client factors that most wealth, advisory and agency firms carry, the main ones are:
| K-factor | Metric | Coefficient | Averaging basis |
|---|---|---|---|
| K-AUM | Assets under management | 0.02% | Monthly values over the previous 15 months, excluding the most recent three |
| K-CMH | Client money held | 0.4% segregated; 0.5% non-segregated | Daily values over the previous nine months, excluding the most recent three |
| K-ASA | Assets safeguarded and administered | 0.04% | Daily values over the previous nine months, excluding the most recent three |
| K-COH | Client orders handled | 0.1% cash trades; 0.01% derivatives | Daily values over the previous six months, excluding the most recent three |
The coefficients are simple. The skill is in the data: defining AUM consistently (including or excluding advised assets, handling delegated mandates), capturing client money and custody balances daily from the systems that hold them, keeping the averaging windows correct as months roll forward, and reconciling every figure back to source. A candidate who can explain how a large new mandate feeds into K-AUM over the following year understands the mechanics; one who quotes only the coefficients has probably reviewed rather than built. Firms dealing on own account carry the risk-to-market and risk-to-firm factors as well, which is a more specialist skill set closer to banking prudential work.
Liquidity, wind-down and the ICARA
Liquidity is the workstream most often treated as an afterthought. Every MIFIDPRU firm must hold core liquid assets of at least the basic liquid assets requirement — broadly one third of the fixed overheads requirement, plus a percentage of any client guarantees — and the ICARA then tests whether that is enough. The person doing this needs to know which assets count, how the requirement moves when fixed expenditure changes, and how liquidity is reported in MIF002.
Wind-down planning is where finance judgement shows most clearly. The ICARA must include a credible plan for an orderly wind-down: a costed timeline, the staff, systems and legal costs of running down the business, the cost of transferring client money and assets, and the triggers that would start the process. From that come the own funds threshold requirement and the liquid assets threshold requirement — the amounts the firm needs to hold to meet the overall financial adequacy rule. The FCA’s Wind-down Planning Guide (WDPG) in the Handbook sets out its expectations.
Public disclosures under MIFIDPRU 8
Non-SNI MIFIDPRU firms must publish disclosures under MIFIDPRU 8, generally annually alongside their financial statements. They cover risk management objectives and policies, governance arrangements, own funds, own funds requirements and the firm’s approach to assessing adequacy, and remuneration policy and practices, with additional investment policy disclosures for the largest firms. SNI firms are generally outside the requirement unless they have issued additional tier 1 instruments. The skill here is consistency and judgement: the published own funds figures must agree with the returns and the audited accounts, and the narrative must be accurate without disclosing more than required. Finance usually drafts the numbers; compliance and HR contribute the governance and remuneration sections, with the MIFIDPRU Remuneration Code shaping what is said.
The skills the work requires
Prudential literacy, not just accounting. The distinction matters. A strong Financial Controller can prepare accounts and still not know why an intangible is deducted from own funds or how a fixed overheads requirement is derived. The prudential frame is learnable but it is not implied by qualification — ICAEW, ACCA or CIMA is the baseline and nothing more.
Data capability. K-factors come from operational systems — portfolio management, order management, client money platforms — and the person doing this needs to extract, reconcile and evidence that data, often monthly. In practice this is the single biggest predictor of whether someone can do the job efficiently or spends every quarter chasing.
Documentation discipline. Every judgement in the ICARA needs to be written down in a form that stands up to supervisory review. Firms that treat the ICARA as an annual document rather than a maintained process are the ones that struggle when questions arrive.
Cross-functional working. The data sits with operations, the risk assessment with risk, the regulatory relationship with compliance. Someone who can only work within finance will produce a return but not an ICARA.
And the judgement to know what matters. A great deal of prudential work is proportionate: a small firm does not need the framework of a large one. Someone who has only worked in a large firm may over-engineer it; someone who has only worked in a small one may under-document. Both are correctable, but worth knowing which you are hiring.
Where firms are typically short
Three gaps recur, and each has a different fix.
Key-person concentration. A common issue, and often the most serious. One person understands the calculation, and everything — the returns, the ICARA, the audit questions — depends on their availability. It is a business continuity issue as much as a hiring one, and the fix is documentation and a second pair of hands rather than a more senior appointment.
The ICARA has no owner. Finance produces the numbers, risk owns the harms, compliance owns the relationship, and nobody owns the document. It is assembled annually under pressure and reads like it. Naming an owner is the single most useful organisational decision available here.
Data extraction is manual. K-factors assembled by spreadsheet each quarter from operational reports, with no reconciliation trail. It works until someone leaves or a number is challenged. This one is usually a systems and process fix rather than a hire, though it is the reason the role feels heavier than it should.
Who does this in practice
The ownership pattern varies with firm size, and getting it right avoids most of the pain.
In smaller investment firms, the Financial Controller or Head of Finance owns the prudential work alongside everything else, frequently with external support on the ICARA. Workable, provided the data extraction is reliable and someone external reviews the judgements.
In mid-sized firms, a dedicated regulatory reporting role emerges, sitting in finance but working closely with risk and compliance. This is the seat most often missing, and its absence is why so many firms produce returns by manual assembly.
In larger firms, a prudential or regulatory reporting function with specialists by workstream.
The transition point is usually the second or third reporting cycle, when the firm realises the work is recurring and material rather than a project — and that the person absorbing it has stopped doing something else. Our guide to finance in an investment firm sets out what the FC owns at each stage.
Testing for the capability at interview
Six core questions that distinguish genuine ownership from adjacency, followed by four that test the wider MIFIDPRU skill set.
1. Walk me through your own funds requirement calculation. The foundational question. Someone who has owned it describes the components and which one bites for their firm; someone who has reviewed it describes the output.
2. How are your K-factors derived, and where does the data come from? This is the question that separates people who have done the work from people who have supervised it. Expect specifics about systems, extraction and reconciliation.
3. What is in your fixed overheads calculation, and what did you exclude? Judgement lives in the exclusions, and the answer shows whether they made the call or inherited it.
4. Talk me through your ICARA — who wrote it, who owns it, how often is it refreshed? Look for a maintained process rather than an annual document, and for someone who can describe the harms analysis rather than only the capital number.
5. Tell me about a submission that went wrong, or a resubmission. Everyone in regulatory reporting has one. Ownership of the error and what changed afterwards is what matters.
6. How would you explain the capital position to a board that is not prudentially literate? The translation test, and the one most often skipped. In-house prudential work lives or dies on being understood by people who make the decisions. Our guide to regulatory capital in the management accounts covers what good reporting looks like.
7. How do you make sure MIF001, MIF007 and the ICARA tell the same story? The FCA has flagged this inconsistency directly. Look for a reconciliation step, not reliance on memory.
8. How did you estimate the wind-down cost, and what drove the liquid assets threshold? Tests whether the candidate built the model or copied last year’s figure.
9. What would move your firm from SNI to non-SNI, and how would you see it coming? Holding client money, or crossing an AUM or order-flow threshold, changes the regime. A good candidate monitors the thresholds rather than discovering the change.
10. Who signs off the MIFIDPRU 8 disclosure, and how do you check it against the accounts? Relevant for non-SNI firms; it shows control discipline over published numbers. For more question banks, see our regulatory reporting interview questions.

Hiring for it: the practical realities
The pool is small and largely employed. Prudential reporting specialists in investment firms rarely appear on job boards; searches rely on direct approach and on knowing who is open to a conversation.
The premium is real. Finance roles in regulated firms typically carry a premium of around 15–25% over equivalent commercial roles, with investment firm Financial Controllers towards the top of that range, and prudential specialism prices above general regulated finance because the pool is thinner still. As a guide, investment firm Financial Controllers typically earn £75,000–£112,000 in London, and interim FCs £440–£600 a day in London (£374–£510 regionally). Benchmarks are in our regulated-firm finance salary guide.
Adjacent experience is often the right answer. Someone from a CRR or banking prudential background, or from a consultancy that has advised on ICARAs, can transfer well — the frame is similar even where the rules differ. What does not transfer is a purely statutory reporting background with no prudential exposure.
And time it away from the reporting calendar. Recruiting in the fortnight before a submission is the hardest version of it; an interim covering a cycle is frequently better than a rushed permanent hire. Our FCA-regulated finance practice covers the market, and hiring for regulatory experience the wider specification question. Senior appointments run across FD Capital Group: CFO, Finance Director and SMF2 searches with FD Capital, and SMF16 and SMF17 roles with SMF Capital.
MIFIDPRU reporting skills: frequently asked questions
Which MIFIDPRU returns does an SNI firm submit?
Typically MIF001 and MIF002 quarterly and MIF007 annually. MIF003 monitoring metrics apply to non-SNI firms, which carry the K-factor requirement.
Does the FC need to write the ICARA?
Not necessarily, but the FC usually owns its numbers — the capital and liquidity projections, stress scenarios and wind-down cost estimate — and in smaller firms often ends up owning the whole document.
Can a commercial FC learn MIFIDPRU reporting?
Yes, given time and support. The rules are learnable; the harder parts are data capability and documentation discipline. Our comparison of regulated and commercial Financial Controllers covers the gap.
