IFR / IFPR K-factors, explained end to end
The third floor, and when it overtakes the other two.
Read the guide →For most investment firms the binding number is not the K-factor result. It is a quarter of last year’s fixed costs — and the whole calculation turns on which costs count as fixed.
Regulation (EU) 2019/2033 sets the own funds requirement as the highest of three amounts: the permanent minimum capital requirement, the fixed overheads requirement, and the K-factor requirement. Firms that meet the conditions to be small and non-interconnected do not calculate the third, so for them the requirement is the higher of the first two.
All three are calculated. The requirement is the maximum, but a supervisor expects to see each of them derived, not only the one that ended up binding.
The requirement is one quarter of the fixed overheads of the preceding year. The starting point is total expenditure for that year from the most recent audited annual financial statements, or unaudited statements where audited ones are not available. Variable and discretionary items are then deducted to leave the costs that would continue if the firm stopped writing new business.
Firms without a full preceding year of operation — newly authorised firms — use the projected fixed overheads from their authorisation, until an actual year exists to calculate from.
The deductible items are defined, not a matter of judgement about what feels variable. The categories that recur in practice:
Where the firm uses tied agents, expenditure relating to their activity is brought into the calculation, since the firm carries responsibility for the business they write.
The permanent minimum capital requirement is a fixed amount determined by what the firm is authorised to do, with higher amounts for firms that deal on own account or underwrite on a firm commitment basis, and lower amounts for firms whose permissions do not extend to holding client money or assets. It is the floor that binds newly authorised firms and firms whose cost base is small relative to their permissions.
Two points are easy to miss. The amount follows the permissions held, not the activities currently carried on — a permission that is dormant still counts. And a change in permissions changes the requirement immediately, without waiting for a reporting cycle.
| Firm profile | Usually binds |
|---|---|
| Newly authorised, minimal cost base | Permanent minimum. |
| Advisory or arranging firm, established | Fixed overheads requirement — the cost base outgrows the minimum quickly. |
| Discretionary manager with substantial assets | Fixed overheads, until the risk-to-client factors overtake it. |
| Firm dealing on own account at volume | K-factor requirement, through the market and firm risk groups. |
