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.

Part one — what you are looking at

The screen in front of you

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.

  • Your decisions. The sliders and toggles you control this quarter. Nothing you set here takes effect until the quarter is processed, so you can change your mind as often as you like while the round is open.
  • Your intelligence panels. The information only your seat can see. This is the material you are expected to bring to the conversation, because the other three cannot look at it themselves.
  • The financial statements. The balance sheet and income statement for the institution as a whole. Everyone sees these, and they are the common ground when the four of you disagree.
  • The scores. How an examiner would grade you, and how you compare with real credit unions of the same size. These update after each quarter is processed.

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.

Part two — what you are running

The institution

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:

  • Members deposit money with you. Checking, savings, money market, certificates. This is not the institution’s money. It is owed back to the member, and you pay interest for holding it.
  • You lend most of it out. Cars, homes, personal loans. The interest members pay on those loans is where most of your income comes from, which is why lending volume matters so much to the institution’s ability to cover its own costs.
  • What you have not lent sits in investments — mostly bonds. These earn less than loans do, but you can turn them back into cash sooner, which matters when members want their deposits back.
  • If you want to lend more than members have deposited, you borrow the difference, mainly from the Federal Home Loan Bank. That borrowing costs more than deposits do, so the more of your lending it funds, the more expensive your growth becomes.

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.

Why the score is not profit

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.

Part three — the four seats

What each seat controls

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.

CEO — chief executive

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.

CFO — chief financial officer

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.

CLO — chief lending officer

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.

CMO — chief marketing officer

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.

Where the seats collide

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.

Part four — how a quarter runs

The loop

Each round is one quarter of the institution’s life, and every round runs the same way:

  • Read the position. What the economy is doing this quarter, and where last quarter left you.
  • Decide, in your own seat. Set your levers and save. Nothing is final until the quarter is processed.
  • Talk to the other three. This is the part teams skip when they are short of time, and the part they later wish they had kept.
  • The CEO processes the quarter. All four sets of decisions go into the engine together, which is why one seat changing its mind late affects what everyone else gets.
  • Read what happened — the statements, the scores, and the summary that points at what is worth a closer look.
  • Debrief, then the next round opens.

Expect about 75 minutes a round: roughly 30 to 45 minutes of decisions and discussion, then a half-hour debrief.

How you are scored

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

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.

🎯 Solo Practice

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.

🏆 Solo Leaderboard

Completed solo runs. Everyone starts from the same credit union in the same scenario, so what separates these scores is the decisions behind them.

EVENTS APPEAR AS BREAKING ALERTS IN PLAYER NEWS WIRE
Select an event below, choose which teams it affects, then fire it. Events appear immediately in the CU News Wire. Three of them now affect the round they are fired in — Cyber Incident, FHLB Restriction and Regulator Visit — and each card says what it does. The other four are discussion prompts and change no engine number.

Two of the three are conditional by design: a team carrying no supervisory findings pays nothing for the Regulator Visit, and a team funded by its own members pays nothing for the FHLB Restriction. That is the teaching point rather than a limitation — the event does not choose who it damages, the balance sheet does. Expect a few Apex points in the round it fires, usually recovered by the next one. If a team is unaffected, ask the room why.
