Finance in an Investment Firm: The FC’s Remit

A Financial Controller in an FCA-authorised investment firm does everything an FC does anywhere — the close, the balance sheet, the statutory accounts, the audit — and then a second job on top of it. That second job is prudential: calculating own funds and the own funds requirement, deriving K-factors from data that lives in operational systems, submitting returns on the regulator’s calendar, and contributing to a document the FCA reads. Many firms underestimate how much of the role that becomes. This guide sets out what the FC actually owns in an investment firm, where the difficulty concentrates, and what the roles typically pay.

It is written for founders, CEOs and finance directors of MiFID investment firms — brokers, discretionary managers, wealth and advisory firms with MiFID permissions — and for accountants considering a move into the sector. If you are ready to recruit, our investment firm Financial Controller recruitment page covers the search itself and what we assess; for the wider picture across payments, insurance intermediaries and asset managers, see our guide to the Financial Controller in FCA-regulated firms.

The prudential half

The Investment Firms Prudential Regime (IFPR) governs UK MiFID investment firms. It took effect on 1 January 2022, replacing the old IFPRU and BIPRU rules, and its detailed requirements sit in the MIFIDPRU sourcebook of the FCA Handbook. Four workstreams follow from it. The FCA’s IFPR pages are the authoritative source, and our guide to regulatory capital, ICARA and the IFPR covers the framework.

A threshold question shapes everything below: is the firm small and non-interconnected (SNI)? SNI status depends on size and activity measures such as assets under management, client orders handled, balance sheet and revenue, and on not holding client money or safeguarding client assets. SNI firms apply a simpler set of rules; non-SNI firms carry the full K-factor calculation and, in most cases, more of the reporting and remuneration requirements. A firm that adds permissions or starts holding client money can cross the line, and the FC should be the first person to see that coming.

Own funds. Determining what qualifies, by tier — Common Equity Tier 1, Additional Tier 1 and Tier 2 within the prescribed limits — after deductions: intangibles, deferred tax assets that rely on future profitability, holdings in financial sector entities. Straightforward arithmetic on a picture that has to be built carefully.

The own funds requirement — the higher of the permanent minimum requirement, the fixed overheads requirement and the K-factor requirement (SNI firms apply only the first two). The permanent minimum requirement is set by permissions at £75,000, £150,000 or £750,000. The fixed overheads requirement is a quarter of the firm’s relevant annual fixed expenditure, normally taken from the most recent audited accounts. The judgement lies in the fixed overheads calculation: what genuinely counts as a fixed overhead and what may be excluded is a decision the FC makes and documents.

K-factors. The activity-based measures, grouped as risk-to-client (assets under management, client money held, assets safeguarded and administered, client orders handled), risk-to-market and risk-to-firm, the last two applying mainly to firms dealing on own account. This is where the practical difficulty sits, because the source data lives in portfolio management, order management and client money systems that finance does not own. Extracting it reliably each period, and reconciling it, is frequently the heaviest recurring task in the role.

And liquid assets — the basic liquid assets requirement, broadly at least one third of the fixed overheads requirement held in core liquid assets, and whether the firm holds enough of the right kind once the ICARA has been considered.

The ICARA

The Internal Capital Adequacy and Risk Assessment sits across finance, risk and compliance, and it is the workstream that most often has no clear owner. It requires the firm to identify the harms it could cause, assess whether own funds and liquid assets are adequate against them, plan an orderly wind-down, and document all of it to a standard a supervisor would accept. The ICARA replaced the ICAAP for investment firms under the IFPR; it must be reviewed at least annually and approved by the governing body, and its key figures are reported to the FCA in the MIF007 ICARA questionnaire.

The FC’s contribution is the financial modelling — capital and liquidity projections, stress scenarios, and the wind-down cost estimate — and in smaller firms the FC frequently ends up owning the whole document by default. Firms that treat the ICARA as an annual exercise rather than a maintained process find it painful; firms that keep the underlying analysis current find it routine. See MIFIDPRU and IFPR reporting skills for the capability question.

What a maintained ICARA process looks like

• A harms register owned jointly by risk, compliance and finance, reviewed when the business changes rather than once a year.
• A capital and liquidity model that ties to the monthly management accounts and the MIFIDPRU returns.
• Stress scenarios with documented assumptions, rerun when trading or client activity moves materially.
• A wind-down plan with a costed timeline, triggers and the liquidity needed to execute it.
• Early-warning indicators reported to the board alongside the capital surplus.

Client money, where it applies

Many investment firms hold client money under CASS 7 and custody assets under CASS 6, and where they do the FC’s remit extends again: the internal and external reconciliations, the client money requirement and resource calculation, acknowledgement letters, the breach register and the CASS audit relationship. The FCA’s client money and assets pages set out the regime.

In smaller firms the FC is frequently also the CASS oversight function, preparing and reviewing their own work — a control weakness worth naming rather than assuming. Our guides to CASS and client money and CASS oversight versus operations cover the ground, and the reconciliation in practice the mechanics.

What changes in the monthly cycle

The close itself is recognisable, with four additions. The capital position becomes a monthly number rather than an annual one, and it belongs in the board pack — as our guide to regulatory capital in the management accounts sets out. Client money reconciliations run on their own frequency, unaffected by the close timetable. K-factor data has to be captured as the period closes rather than reconstructed. And the regulatory calendar overlays the management one, with submission dates that do not move for a difficult month. Our guide to the close at a regulated firm covers the wider changes.

Regulatory returns through RegData

All of this turns into data the FCA collects through RegData, which replaced the old GABRIEL system. For a MIFIDPRU firm the core prudential items are the quarterly own funds and own funds requirement return (MIF001) and the liquidity return (MIF002), with the ICARA questionnaire (MIF007) annually and further MIFIDPRU items depending on size and activities. Firms holding client money or assets may also submit the Client Money and Asset Return (CMAR) where their CASS classification requires it, and many firms carry other financial data items on their reporting schedule.

The FC’s job is not only to file. It is to make sure the number in the return, the number in the management accounts and the number in the ICARA are the same number, or that the difference is explained. Our guide to RegData, COREP and FINREP covers the returns, and the regulated-firm FC guide sets out the full returns calendar across firm types.

SMCR and where the FC sits

The Senior Managers and Certification Regime applies to all FCA solo-regulated investment firms, but how it touches the FC depends on the firm’s category. In enhanced firms the Chief Finance Function (SMF2) is a designated senior manager, approved by the FCA before taking up the role. In most core firms there is no SMF2; responsibility for finance usually sits with the CEO or an executive director holding a senior manager function, and the FC is subject to the Conduct Rules and, depending on the role, may fall within the certification regime. Where the firm holds client money or assets, responsibility for CASS compliance must be allocated to a senior manager — and the FC is often the person who supports them day to day.

In practice, the FC in a smaller investment firm frequently prepares the financial evidence that senior managers rely on for their statements of responsibilities, and should know which responsibilities rest on their work. Our guide to SMCR for finance teams explains the regime. Within FD Capital Group, SMF2, CFO and Finance Director searches run with our sister firm FD Capital, and SMF16 compliance oversight and SMF17 MLRO appointments with SMF Capital.

Where firms struggle

Key-person concentration. A common issue, and often the most serious. One person understands the calculation, has built the spreadsheets, and knows why each judgement was made — none of it documented. The firm functions until they are unavailable in the wrong week.

Manual K-factor extraction. Assembled by spreadsheet each quarter from operational reports with no reconciliation trail. It works until a number is challenged.

The ICARA with no owner, assembled annually under pressure and reading like it.

Fixed overheads judgements undocumented, so the basis cannot be explained when the calculation is questioned a year later.

And prudential literacy assumed rather than built. A strong commercial FC can prepare excellent accounts and not know why an intangible is deducted from own funds. That is learnable, but it has to be recognised as a gap rather than assumed away. Our comparison of regulated and commercial Financial Controllers covers the difference.

Investment firm finance salaries

The Financial Controller range runs from SNI execution-only brokers at the lower end to discretionary investment managers at the upper end; an FC who is also the SMF2 designate at an enhanced-regime firm can command more — our investment firm FC recruitment page breaks the band down by firm type. Investment firm FCs typically price around 18–25% above equivalent commercial roles, with prudential and CASS experience the main reason; why regulated finance roles pay more explains the premium. Note that at larger non-SNI firms, remuneration for material risk takers is subject to the FCA’s remuneration requirements, which can include deferral, malus and clawback and changes the cash timing against an unregulated equivalent. Wider benchmarks are in our regulated-firm finance salary guide.

Hiring for the role

Three practical points. Specify the prudential half explicitly — a specification describing a standard FC role will attract commercial candidates who then discover the regime, and the mismatch surfaces at the first submission. Test the data question hard: where the K-factors come from and how they reconcile tells you more about whether someone can actually do this job than any amount of regime knowledge. And consider adjacent backgrounds — someone from a CRR or banking prudential environment, or from a consultancy that has advised on ICARAs, transfers well; a purely statutory background with no prudential exposure does not.

Qualification is the baseline — ICAEW, ACCA or CIMA — and audit-trained candidates who have audited investment firms are an under-used source. Our investment firm FC practice covers the search and hiring regulatory experience the wider specification question.

Permanent, interim or fractional?

A firm with a stable permission set and a growing balance sheet usually needs a permanent FC. Interim cover suits a vacancy before a submission date, a CASS remediation or a first ICARA under pressure; fractional cover suits smaller SNI firms whose prudential work is real but does not fill a week. Our guide to fractional and interim finance in FCA-regulated firms covers the options, and we can usually present interim or fractional candidates within days.

Questions worth asking at interview

• Walk me through how you built the own funds calculation at your last firm, including the deductions.
• How did you decide what to exclude from relevant fixed expenditure, and how was it documented?
• Where did your K-factor data come from, and how did you reconcile it to source systems?
• What did you contribute to the ICARA, and how was the wind-down cost estimated?
• Describe a CASS reconciliation break you resolved and how it was reported.

Finance in an Investment Firm: FAQs

When did MIFIDPRU come into force?

The IFPR and the MIFIDPRU sourcebook applied from 1 January 2022, replacing IFPRU and BIPRU for UK MiFID investment firms. Experience under the old regimes is still useful background, but candidates should be able to work in MIFIDPRU terms.

Does an SNI firm need a specialist FC?

An SNI firm still has to calculate own funds, the permanent minimum and fixed overheads requirements, liquid assets and the ICARA, and to file MIFIDPRU returns. It may not need a full-time specialist, which is why fractional regulated FCs are common at this size.

Who owns the ICARA?

The governing body approves it. In practice finance, risk and compliance share the work, and the FC usually owns the capital and liquidity modelling, stress testing and wind-down costings.

Does our Financial Controller need FCA approval?

Only if the role is itself a senior manager function — for example SMF2 in an enhanced firm. Most FCs in core firms do not need pre-approval, though they are subject to the Conduct Rules.

How quickly can you find an investment firm FC?

We respond the same working day. Permanent shortlists typically arrive within one to two weeks, and interim or fractional candidates within days. Fees are agreed in writing before a search starts.
