What it means
At its core, investment management is a delegation arrangement. A pension scheme, a company treasury or an individual hands over capital along with a mandate that sets out what may be bought, what must be avoided and what the money is trying to achieve.
The reason organisations delegate is capability and time. Running a diversified portfolio needs research, dealing infrastructure, custody arrangements and constant monitoring, none of which a finance team of three can sensibly maintain alongside its day job.
The process usually runs in four steps: set the objective and risk tolerance, decide the asset allocation, select the individual holdings, then monitor and rebalance. Most academic work suggests the allocation step drives the bulk of long-run results, yet clients often spend their attention on which particular shares were bought.
Fees are the practical detail that determines whether the arrangement is worth having. A typical institutional mandate might charge 0.3% to 0.8% of assets a year, while performance fees add a share of returns above an agreed hurdle rate, and both are levied whether markets rise or fall.
The nuance worth knowing is the difference between investment management and wealth management. Investment management is about the portfolio itself, whereas wealth management wraps tax, estate and financial planning around it, and the two are often sold together but priced separately.
In practice
Real-world examples
Example 1
A local authority pension fund splits a $400,000,000 mandate between a passive equity manager charging 0.08% and an active bond manager charging 0.45%. The split reflects a view that bond markets offer more scope for skill, and it holds the blended fee to roughly 0.2% overall.
Example 2
A manufacturing group appoints an investment manager for its $25,000,000 pension surplus with a strict mandate excluding tobacco, weapons and thermal coal. The exclusion list is written into the investment management agreement, so a breach is a contractual matter rather than a conversation.
Example 3
A family office fires its manager after three years, not because returns were poor but because the quarterly reports never explained what drove them. The replacement charges 0.1% more and provides attribution analysis showing exactly which decisions added or cost money.
Think of it
Investment management is like tending a vegetable garden. You do not just plant everything in one spot and hope for the best. You pick a variety of crops, water them carefully based on the weather, pull weeds when necessary, and harvest them at the right time.
Formula
Calculation
Formula: Management fee = assets under management x fee rate. Performance fee = (portfolio return - hurdle rate) x assets under management x performance fee rate. Net return = gross return - total fees.
Worked example: a charity places $80,000,000 with a manager on a 0.65% base fee plus a 10% performance fee above a 6% hurdle. The base fee is $80,000,000 x 0.0065 = $520,000.
The portfolio returns 9% for the year, so the excess over the hurdle is 9% - 6% = 3%, which equals $80,000,000 x 0.03 = $2,400,000. The performance fee is $2,400,000 x 0.10 = $240,000.
Total fees are $520,000 + $240,000 = $760,000, or $760,000 / $80,000,000 = 0.95% of assets. The gross gain was $80,000,000 x 0.09 = $7,200,000, so the charity keeps $7,200,000 - $760,000 = $6,440,000, a net return of 8.05%.Case study
Seen in the real world
Thornbury Foundation is an invented charitable trust used for this illustrative case study. It held an $80,000,000 endowment and had used the same manager for a decade on a 0.65% base fee plus a 10% performance fee above a 6% hurdle.
In one strong year the portfolio returned 9%, generating $7,200,000 of gross gains. Fees came to $520,000 base plus $240,000 performance, so $760,000 in total, and the trustees noticed that the effective charge had risen to 0.95% of assets in exactly the year they felt best about the results.
The illustrative point is that the trustees were not being cheated; they were being charged what they had agreed. They renegotiated so the performance fee applied only to returns above a rolling three-year hurdle, which removed the reward for one good year following two weak ones.
Watch out
Common mistakes
- Judging a manager on one year of returns, when a single year says far more about which asset class did well than about the manager's decisions.
- Signing a mandate without reading the fee schedule to the end, so custody, dealing and administration charges arrive on top of the headline management fee.
- Confusing the benchmark with the objective, because beating a falling index by two points still means the money is worth less than it was.
Questions
People also ask
What does assets under management actually mean?
It is the total market value of the client money a manager is responsible for, and it is the base on which most fees are calculated.
Is a performance fee fairer than a flat fee?
Not automatically, since a poorly designed performance fee rewards a manager for market movements they did not create unless there is a sensible hurdle and a high-water mark.
How often should a mandate be reviewed?
Most institutions review formally once a year and check performance quarterly, which is frequent enough to spot drift without encouraging reactive changes.
