You are about to run a credit union from a seat you do not sit in today. That is the point of the exercise, and it is worth saying plainly: you are not expected to arrive knowing how the other three seats work. Most people who do this job well learned it the same way, by holding the seat and finding out what it is connected to.
This section is the orientation. It covers what you are looking at, what you are running, what each of the four seats controls, where those seats pull against each other, and what a quarter actually looks like. Fifteen minutes here will save you a round of confusion later.
Your seat has its own screen, and it is organised the same way for all four officers. Before anything else, it is worth knowing which part is which, because the names come up constantly in discussion.
If you would rather see this than read about it, the tutorial walks through one quarter with no account and nothing at stake. It is the fastest way to get the shape of the screen into your head.
Lakeside Community Credit Union holds about $743 million in assets. It is not a real credit union, but every number it starts with is: the opening balance sheet is built from what credit unions of this size actually reported to the NCUA.
A balance sheet is a list of what the institution owns and what it owes, on one particular day. For a credit union the shape of it is simple, and worth holding in your head, because every decision any of you make moves one of these four things:
What is left after you subtract everything you owe from everything you own is your net worth — the cushion. Regulators watch it more closely than anything else, because it is what absorbs losses before members are exposed to them.
You already know the structural answer: nobody owns a credit union except its members, so there are no shareholders waiting on a return. What that changes in practice is what you are optimising for.
Earnings still matter a great deal. An institution that loses money is eroding the cushion that protects its members, and it cannot invest in anything — branches, technology, staff — without first covering its own costs. But earnings are the means here rather than the objective. A quarter that makes unusually good money by taking on risk the institution cannot carry is not a good quarter, and the exercise is built so that shows up before the end rather than after it.
Four officers, one balance sheet. Each seat has its own controls and its own information, and no seat can see everything. That is deliberate. It is also the reason the conversation between the four of you matters more than any single decision one of you makes.
Sets the capital target — how much cushion the institution holds in reserve — and the overall posture for the quarter. Decides whether to pay members a bonus dividend. Processes the quarter once everybody has submitted. The CEO does not see any one area in as much detail as the officer who runs it; what the CEO has instead is the only view that spans all four seats. That makes the job connecting what the others are reporting rather than out-analysing them.
Prices what the institution pays members on their deposits, and decides what to do with the investment book and any borrowing. When lending outruns deposits, the CFO is the one who funds the difference and lives with what it costs. This seat sees how quickly each side of the balance sheet reprices when rates move, and what the investments are worth if they had to be sold today — neither of which the other three can see.
Sets the credit box — the lowest credit score and the highest loan-to-value the institution will accept — prices the loans, and decides how much to originate in each product. This seat sees delinquency broken out by product and by when the loan was written; everyone else sees only the total. Lending decisions take the longest of anyone’s to show their consequences, often two or three quarters, which makes this the hardest seat in which to judge your own performance.
Decides what to spend on marketing and on digital capability, how to split effort between branches and digital channels, and what to target for new members. This seat sees member satisfaction broken out by segment, which is the earliest warning the institution has, because satisfaction moves before balances do. New members arrive with very small balances and build up over several quarters, so most of what this seat does pays off well after the quarter that paid for it.
The four seats are not four separate jobs. They are four roles that affect the same balance sheet, and most quarters each one can pull that balance sheet in a different direction if the team is not careful. These are the arguments that come up. None of them are settled by one seat being right.
Deposit pricing. The CMO watches members move their money elsewhere when deposit rates fall behind the market, and the institution cannot operate without members and the deposits they bring. The fix is to pay more for deposits. But the CFO has to watch the cost of funds, and the CFO is measured on margin, because margin is what covers the net cost of running the institution. Nobody is wrong. Somebody has to decide how to balance growth against efficiency this quarter.
Funding the loan book. The CLO can write more loans than the deposit book covers, and writing more is not greed — lending is where the income comes from. But every loan has to be funded by something, and when deposits do not cover it the difference is borrowed at a higher cost. Arranging that is the CFO’s problem and it lands in the CEO’s capital position. A lending plan that nobody has funded will either shrink when it meets reality, or be paid for with borrowing the team never discussed.
The capital target. The CEO decides how much net worth to hold in reserve. Holding more is the safer choice and no examiner will ever fault you for it. It also means that money is sitting still rather than being lent or invested, which quietly limits what the other three can do. That constraint often goes unsaid, which is how a team ends up arguing about lending volume when what they actually disagree about is capital.
Growth that arrives later. The CMO spends this quarter on members who will not matter financially for several quarters. The CFO pays for that spending now, in a quarter that is scored now. Whether it reads as investment or as waste depends on how far ahead the team is willing to look, and that is a conversation worth having in round one rather than round five.
Teams that talk before they submit tend to notice these. Teams that work in parallel usually discover them a round later, in the results.
Each round is one quarter of the institution’s life, and every round runs the same way:
Expect about 75 minutes a round: roughly 30 to 45 minutes of decisions and discussion, then a half-hour debrief.
Your Apex Score combines two things, each of which a real board would recognise.
The regulatory half is CAMEL, the five components a credit union examiner grades: Capital — is the cushion thick enough; Asset quality — is the lending sound; Management — is the institution run efficiently and consistently; Earnings — does it make enough to sustain itself; and Liquidity — can it reach cash when it needs to. If capital falls far enough, a hard floor caps your score no matter how well everything else is going. That is also how it works outside the exercise: below certain capital levels a regulator restricts what an institution is allowed to do, whatever the rest of its performance looks like.
The peer half compares you with what credit unions of the same size actually reported in the same quarters. It is not a target somebody invented. It is what the filings say happened.
There is no single right answer, and you should not expect to find one. Reasonable teams approach the same scenario differently and finish within a few points of each other by quite different routes.
Your first round will feel like you have either too much information or not enough. That is not an oversight. As you play, you will learn how to ask your teammates for the information that helps you make your decisions, and you will learn which of the things in front of you are genuinely valuable and which are noise.
Two habits help more than anything else. Ask the other three what they are seeing. Their panels hold information yours does not, and asking is the intended mechanic rather than a workaround — the exercise is built on the assumption that you will. And do not change everything at once. If six levers move together, nobody learns which one did the work, and the next quarter is harder to reason about than this one was.
Tell us a little about your team and we will get back to you. Nothing here is required to use the simulation — the tutorial stays open to everyone.

A one-minute walk through the screen — what each part is and where decisions get made.
A quick orientation before you run your first quarter — no login required
CU ApexSim puts you in the executive chair of a credit union — Lakeside Community Credit Union, a $743M institution modelled on NCUA 5300 call report data for the $500M–$1B peer tier.
Your team of four makes real management decisions each quarter and competes against peer institutions on a regulator-calibrated scorecard.
A note on screen size: the full simulation is built for a tablet or a laptop — four decision panels and a complete set of statements need the room. This tutorial runs here and you will see everything; it is a squeeze, and a bigger screen is worth it when you play properly.
Each role has unique decisions and private information. No single person sees everything — you have to coordinate.
Sets capital targets, growth posture, and staffing. Only role that sees all four executive summaries and submits the final round command.
Controls investment portfolio and deposit pricing. Sees full ALM risk picture others don't receive automatically.
Sets loan volumes, rates, and credit standards. Only role that sees the loan book by VINTAGE — the credit quality written in each quarter, and how it surfaces later.
Grows membership and protects the deposit base. Receives the private Member Satisfaction Index each quarter.
Each round = one simulated quarter (3 months). In a real session, rounds run over days or weeks. In tutorial mode, all four roles are unlocked so you can explore everything at once.
Your Apex Score (0–100) blends two components benchmarked against real credit union outcomes:
Apex 80+ = Strong (CAMELS 1) · 65-79 = Satisfactory (CAMELS 2) · 50-64 = Fair (CAMELS 3) · 32-49 = Marginal (CAMELS 4) · <32 = Unsatisfactory (CAMELS 5).
The full calibrated simulation is live. Here's what to do first:
Pick up where you left off, or start a solo run.
Loading your sessions…
Take over Lakeside Community Credit Union as all four executives and run it through a full scenario. Your final score posts to the solo leaderboard under your name.
How long is a run?Scenario length Each scenario runs its own arc — six quarters for The Great Unwind, eight for The Shock, twelve for The Long Cycle. Rounds beyond the scenario's authored arc freeze on the final quarter's economic conditions.
What does difficulty change?Only what happens TO you The economy, the balance sheet you inherit and the scoring are identical at every setting. A disruption costs a well-positioned institution very little, so this is a test of the position you have built rather than a handicap. Scores are only comparable within a tier.
