# Decoding the acronym soup
A portfolio manager opens a client meeting: "We run 40 bps on the SMA, but the pooled version is a CIT at 32, and the TDF glidepath sits inside the DC plan." If that sentence lost you at "bps," you were not alone in the room. Half the acronyms in asset management describe *what you own*, the other half describe *what it costs*. Learn to sort them and you can read any fact sheet in ninety seconds.
Start with the number every conversation orbits: AUM (Assets Under Management), the total market value of assets a firm manages on behalf of clients with discretion (meaning the firm makes the buy and sell decisions).
Global AUM is estimated at roughly $130 trillion (2024 year-end estimates, per BCG's Global Asset Management report). The US is the largest single market, and Europe is the second-largest region. For scale, the two biggest managers, BlackRock and Vanguard, each run assets in the multiple-trillions range; BlackRock alone reported over $11 trillion in AUM (2024 year-end). Those two plus State Street dominate the passive end.
Do not confuse AUM with AUA (Assets Under Administration). AUA is assets a firm *services* (custody, record-keeping, reporting) but does not make investment decisions on. Custodian banks like State Street or BNY report enormous AUA. A firm can have small AUM and vast AUA, or vice versa. The economics differ completely: AUM earns management fees, AUA earns thinner servicing fees.
> Quick check: if a pitch deck leads with a giant "assets" number, ask "AUM or AUA?" It changes the revenue story entirely.
NAV (Net Asset Value) is the per-share value of a fund: total assets minus liabilities, divided by shares outstanding. A mutual fund strikes one NAV per day, usually after market close. When you buy a fund at "NAV," you pay exactly what the underlying holdings are worth, no more.
The NAV is where fees quietly bite, which brings us to the cost cluster.
bps (basis points) is the unit everyone quotes fees in. One basis point = 0.01%. So 100 bps = 1%. A fee of "50 bps" means 0.50% per year. Professionals say "bips" out loud.
TER (Total Expense Ratio) is the all-in annual cost of running a fund, expressed as a percentage of assets: management fee plus admin, custody, audit, and other operating costs. In Europe you will more often see OCF (Ongoing Charges Figure), which is essentially the modern, standardized version of the TER under EU fund-disclosure rules. Treat them as near-synonyms for practical purposes; OCF is the term you will find on a European KID (Key Information Document), the mandatory one-page cost-and-risk summary for retail funds.
You invest $100,000 in a fund with an OCF of 75 bps (0.75%).
Now compare a passive equivalent at 8 bps (0.08%):
Same market exposure, a $670 annual difference. Over 20 years, compounding that gap, the cheaper fund can leave you tens of thousands of dollars ahead. This single calculation explains the entire multi-decade shift toward passive investing.
These describe the *wrapper*, the legal container your money sits in. The wrapper changes cost, tax, and who can access it.
ETF (Exchange-Traded Fund): a fund that trades on an exchange like a stock, priced continuously through the day rather than once at NAV. ETFs are usually cheap, tax-efficient in the US, and can be passive (tracking an index) or active. US ETF assets are estimated in the $10 trillion-plus range (2024 year-end estimates); Europe's ETF market is large and growing fast but materially smaller.
CIT (Collective Investment Trust): a pooled vehicle available only inside US employer retirement plans (like 401(kkThe average number of new users each existing user generates through referrals. Above 1.0, growth compounds on itself and becomes exponential.Voir la définition complète →)s), run by a bank or trust company. CITs are not registered like mutual funds, carry lighter disclosure requirements, and are often cheaper. That is why the manager in our opening scene quoted the CIT at 32 bps versus 40 bps for the SMA: same strategy, cheaper wrapper.
SMA (Separately Managed Account): the client owns the individual securities directly in their own account, rather than owning shares of a pooled fund. SMAs allow customization (tax-loss harvesting, excluding certain stocks) and are common for wealthier clients.
These name *what the money is trying to do*.
TDF (Target-Date Fund): a single fund that automatically shifts from stocks toward bonds as a target retirement year approaches. A "2050 fund" holds more equities today and de-risks over time. The path of that shift is called the glidepath. TDFs are the default option in most US 401(kkThe average number of new users each existing user generates through referrals.

They are the reason "set and forget" retirement saving works for millions of people.
LDI (Liability-Driven Investing): a strategy, mostly used by pension funds, that matches investments to future payout obligations (the liabilities) rather than chasing maximum return. LDI made global headlines in 2022 when a sharp rise in UK government bond yields forced LDI-using pension funds into a scramble for cash, promptingpromptingPrompt engineering is the practice of designing and refining text inputs to guide large language models toward accurate, relevant, and reliable outputs.Voir la définition complète → emergency Bank of England intervention.

Put it together. When a fund fact sheet or pitch deck lands, run this checklist:
1. Assets: AUM or AUA? Discretionary management or just servicing?
2. Wrapper: ETF, mutual fund, CIT, or SMA? This drives cost, access, and tax.
3. Cost: what's the OCF/TER in bps? Convert to dollars on the client's actual balance. A 75 bps fund on $500,000 is $3,750 a year.
4. Strategy: active or passive? TDF, LDI, or plain index? Know what the money is actually doing.
5. Benchmark and tracking: for a passive fund, how closely does NAV track its index (the "tracking difference")? For an active fund, does performance justify the fee gap versus a cheap index alternative?
This is the calculation professionals run constantly. An active US equity fund charges 65 bps; a comparable index ETF charges 5 bps. The active manager must beat the index by 60 bps per year, after costs, just to break even with the cheap option. Most do not, consistently, over long periods. Free sources like the S&P SPIVA scorecards track exactly how many active funds underperform their benchmark, and the numbers are sobering. That data, more than any argument, explains the passive tide.
When you operate in this sector, a few practical checks separate the fluent from the fooled:
