MiFID II costs and charges disclosure: ex ante, ex post and no surprises

Clients have the right to know how much they pay, to whom, and how it affects their return. We set up your firm’s costs and charges process so that every figure adds up: ex ante, annual ex post and itemized breakdown on request.

Do your cost figures match what the client receives?

Who struggles with cost disclosure

Four typical firms with the same symptom (figures that do not match across systems, templates and contracts) and a different point of failure.

Retail banking

The branch network with thousands of annual ex post statements

“We generate the annual cost statement in bulk, and nobody checks that it reaches every client or that the product data is complete. A well-aimed complaint would put us in a difficult position.”

EAF

The adviser who charges fees, and something more

“We disclose our fees properly, but the product costs and the retrocessions on the share classes we use do not always appear in the aggregate. We want to close that gap before the CNMV sees it.”

Platform

The digital channel with its own simulator

“Our ex ante simulator shows the purchase fee, but not the product’s ongoing costs or the cumulative effect over several years. We need to rebuild it on a legal basis, not just a design one.”

Management company

The fund manager (SGIIC) that supplies its distributors

“The banks that sell our funds ask us for consistent, timely cost data. If our data arrives wrong, the error is multiplied across thousands of communications to end clients.”

The three classic gaps in cost disclosure

Almost all supervisory cases and complaints about costs fit one of these three patterns. They are avoidable and, if caught in time, cheap to fix.

Incomplete ex ante simulators: tools that show the visible fee but leave out product costs, ongoing costs or the illustration of the cumulative effect on return. The client decides on the basis of a cropped picture, and your evidence is flawed from the start.

The ex post statement that never arrives: annual statements that are not generated for all clients, that sit unannounced in digital mailboxes nobody opens, or that show aggregates which do not make clear what was paid. The obligation is annual and per client, not statistical.

Hidden inducements: retrocessions received from third parties that are not itemized in the cost disclosure. This is the finding that turns a routine review into a credibility problem with the supervisor and with the client.

What to disclose at each stage (MiFID II Art. 24(4) and Art. 50 of Delegated Regulation 2017/565)
Stage What you must disclose Evidence you must keep
Ex ante (before the service or transaction) Aggregated costs of the service and the product, inducements included, with the illustration of the cumulative effect of costs on the expected return. Simulations or documents provided, with date and content, linked to the client and to the specific transaction.
Ex post (annual) Actual costs and charges incurred during the year, aggregated and personalized for each client, including retained third-party payments and their effect on return. Annual statement generated and made available to each client, with a record of issue, channel and reproducible content.
On request from the client Item-by-item breakdown of what the aggregate summarizes: service costs, product costs, inducements and payments to third parties. Log of requests and responses, with reasonable response times and traceability of the breakdown provided.

Every euro disclosed should add up

We audit your data sources, simulators, templates and annual statements; we reconcile inducements with breakdowns; and we leave the process documented, with owners and controls. So that the next CNMV review or the next complaint finds a closed, well-documented file.

MiFID II costs and charges: questions from firms

What exactly does MiFID II require on costs and charges?

Article 24(4) of MiFID II, supplemented by Article 50 of Delegated Regulation (EU) 2017/565, requires firms to inform clients of all associated costs and charges: those of the investment service, those of the instrument and third-party payments. The information is presented in aggregated form at two points in time (ex ante and annually ex post), with an itemized breakdown on request from the client and an illustration of the cumulative effect of costs on return.

What should the ex ante information include?

An aggregated, understandable view of what the client will pay if they sign up: service costs (commissions, fees, custody), product costs (including those embedded in the instrument) and any inducements the firm retains. It must be provided sufficiently in advance for the decision to be an informed one.

The usual failure is not total omission but partial omission: simulators that show the transaction fee and say nothing about the product’s ongoing costs or the effect over several years.

What is the illustration of the cumulative effect on return?

A representation (numerical or graphical) of how total costs reduce the return on the investment over time, so that the client sees the real impact and not just an isolated annual percentage.

It is the most overlooked element in digital developments and one of the first things a reviewer spots: if your simulator or your ex post statement does not include it clearly, the process is incomplete.

Do inducements have to appear in the breakdown?

Yes. The third-party payments your firm retains must be shown to the client, itemized separately within the cost disclosure. An inducement permitted under MiFID II Art. 24 but invisible in your templates is no longer defensible.

The acid test is reconciliation: what your agreements with manufacturers say must match what your clients see. The full regime is covered in MiFID II retrocessions and inducements.

Who should receive the ex post information, and when?

Annually and personalized for each client, covering the actual costs and charges incurred in the period, where the relationship requires it under the rules (notably where there is an ongoing relationship). Generating it is not enough: you must actually make it available and be able to prove that you did.

The risk patterns: groups of clients mistakenly left out of bulk processes, digital mailboxes with no notification, and statements that make it impossible to reconstruct what was charged.

Can I limit this information for professional clients?

The rules allow certain requirements to be applied in a more limited way to professional clients and eligible counterparties, on the terms and within the limits they set; for retail clients, the standard applies in full.

Before relying on any limitation, review your client classification and document the agreements: a wrongly assigned category turns the “limitation” into a breach toward retail clients.

How does this information relate to the PRIIPs KID?

They are separate layers whose data must be consistent: the KID describes the costs of the packaged product; the MiFID disclosure aggregates product, service and inducements for the specific transaction or relationship.

When the figures in the two do not match (because the data sources are different or out of date), the client receives two different truths, and that fuels both complaints and requests for information.

What happens if a client complains about incorrectly disclosed costs?

Cost complaints tend to succeed when the firm cannot reconstruct what was disclosed, when and with what content. Your defense is the record: ex ante simulations linked to the transaction, ex post statements issued and breakdown requests answered.

If the matter escalates, the client can turn to the CNMV complaints service, whose reports are not binding but carry interpretive weight. Reaching that stage with your file in order changes the outcome.

Building a costs process that always adds up

Cost transparency is, above all, a problem of data and of process ownership. This is the route we follow to get it working.

Phase 1

Inventory of costs and sources

We catalog every item the client bears (service, product, third parties) and the system each data point comes from. Most errors start here: duplicated sources, empty fields and products with no ongoing cost data.

Phase 2

Templates and delivery points

We design the ex ante documents (simulator, pre-contractual document), the annual ex post statement and the breakdown on request, with the cumulative effect on return and visible inducements. And we set when and through which channel each one is delivered.

Phase 3

Controls and evidence

Periodic reconciliations between contracts, systems and communications; an ex post coverage control (no client left out); and a reproducible archive of everything delivered. The process ends up with an owner, a calendar and metrics.

The costs and charges process in 10 steps

  1. Cost catalog: inventory every cost the client bears: service, product, execution, custody, currency exchange and third-party inducements.
  2. Data source map: identify which system or provider each data point comes from and who is responsible for its quality and updating.
  3. Product coverage: check that the whole product range has usable cost data; gaps in product data are gaps in client information.
  4. Aggregated ex ante: build the prior information with aggregated service and product costs, inducements included, delivered before the decision.
  5. Cumulative effect: include the illustration of the impact of costs on return, understandable and present both ex ante and ex post.
  6. Annual ex post statement: generate the personalized statement for each client with the actual costs for the period, and control its coverage and how it is made available.
  7. Breakdown on request: define the procedure for handling requests for item-by-item detail, with deadlines and a log.
  8. Inducement reconciliation: regularly reconcile third-party agreements against what is shown to the client; every difference is a finding.
  9. Consistency across layers: align figures across simulators, contracts, PRIIPs KIDs and statements so that the client receives a single version of the truth.
  10. Archive and metrics: keep everything delivered in a reproducible form and measure the process: coverage, incidents, complaints and corrections.

This process is one of the areas we review in our MiFID II compliance service; if your question is what can be received from third parties, start with retrocessions and inducements.

Practical glossary

The terms of the costs process

Nine concepts that structure Art. 50 of Delegated Regulation 2017/565 and that should be fine-tuned in your templates and procedures.

Ex anteTiming

Before deciding

Information prior to the service or transaction: aggregated service and product costs, inducements included, so the client can decide with data.

Provided sufficiently in advance.
Ex postTiming

The annual reckoning

Personalized annual statement of the actual costs and charges borne by the client during the period.

Full coverage: no client left out.
AggregationFormat

The understandable total

All costs added together and shown as an amount and a percentage, so the client sees the whole picture without digging through line items.

The detail is left for the breakdown.
Breakdown on requestRight

Item by item

The client’s right to ask for an itemized breakdown of the aggregate: service, product, third parties and inducements.

Procedure and log required.
Cumulative effectImpact

Costs versus return

Illustration of how total costs reduce the return on the investment over time.

The element most simulators leave out.
Service costsConcept

What your firm charges

Fees and commissions for advising, managing, executing or holding in custody, including ancillary charges linked to the transactions.

Must match the contract and the fee schedule.
Product costsConcept

What is embedded in the instrument

Costs built into the product (management, transaction, structuring) that the client bears even if they do not see them on the account statement.

Require reliable manufacturer data.
Inducements in the breakdownThird parties

The payment you show

Third-party payments retained by the firm, itemized separately in the cost information given to the client.

Their absence is the classic finding.
Adjustment by categoryScope

Professional clients and counterparties

The option to adjust certain requirements for non-retail clients on the terms set by the rules; for retail clients, the full standard applies.

Depends on correct classification.

Log of requests with response times, the breakdowns delivered and a repository retrievable by client.

Signs that your cost disclosure is springing leaks

Five quick checks: if you fail any of them, the process needs a review before a third party forces one.

  • Your ex ante simulator does not show the product’s ongoing costs or any illustration of the cumulative effect over several years.
  • You cannot say what percentage of your clients actually received the ex post statement for the last financial year.
  • The retrocessions set out in your agreements with management companies do not appear in, or do not match, what clients see.
  • The product KID, the contract and your MiFID disclosure give different cost figures for the same investment.
  • Faced with a breakdown request, it would take you weeks to reconstruct the line items because the data lives in three systems with no owner.

MiFID II costs and charges: what to disclose, when and with what evidence

If there is one MiFID II obligation that clients can check for themselves, it is this one. Article 24(4) of Directive 2014/65/EU and Article 50 of Delegated Regulation (EU) 2017/565 require firms to disclose all costs and charges associated with the service and the instrument (third-party inducements included), in aggregated form, at two points in time (ex ante and annually ex post), with an itemized breakdown on request and an illustration of the cumulative effect of costs on return. On paper it is simple; in practice it is a problem of data, systems and process ownership that few firms have truly solved.

Ex ante: deciding with full knowledge of the cost

Before the service or transaction, the client must receive the total aggregated cost: what the firm charges for the service, what is embedded in the product and what the firm retains from third parties. In digital channels, this obligation lives in the simulators, and that is where the typical error lies: showing the purchase fee and leaving out the product’s ongoing costs or the effect over several years. An incomplete ex ante disclosure is not a cosmetic defect: it is an investment decision made with partial information, which is exactly what the rule seeks to prevent.

Annual ex post: the real figure, client by client

Once a year, the firm reports the costs and charges actually incurred, personalized for each client and aggregated, with their effect on return. The recurring failures are operational: groups of clients left out of the bulk process, statements deposited in mailboxes nobody checks, and incomplete product data that distorts the total. In discretionary portfolio management, where the client delegates, this annual statement is the main window of control the client has left: the supervisor knows this and looks at it.

Inducements and breakdown: what is not seen does not exist (until it surfaces)

Retained third-party payments must be itemized separately in the cost disclosure, consistent with the MiFID II Art. 24 inducements regime. And any client can demand an item-by-item breakdown of the aggregate. The robustness test for the process is twofold: reconciliation between agreements with manufacturers and client templates, and the ability to answer a breakdown request within a reasonable time without heroic reconstructions. Consistency with the other layers (the PRIIPs KID, the contract, execution costs) completes the picture.

Complaints, supervision and how we work

Poorly disclosed costs feed two fronts at once: client complaints (with the CNMV complaints service as the usual arena) and supervisory reviews that ask the firm to reconstruct what was disclosed and when. Our work with banks, investment firms, EAFs and management companies: an audit of the full process (sources, templates, simulators, ex post, breakdown), inducement reconciliation, a remediation plan and an evidentiary archive, as part of our MiFID II compliance service and tailored to each client’s category.
