Reserve Management

The Three Laws of Reserve Fund Protection

Reserve funds exist to protect homeowners from special assessments. These three laws define what protection actually means and how to verify your reserves are truly protected.

Reserve funds protect homeowners from the shock of unexpected special assessments. When the roof needs replacing or the elevator needs modernization, a properly funded reserve means the money is already there.

But reserves are only protected if they are actually protected. Three fundamental laws determine whether your reserves are safe or vulnerable.

Law 1: Separation Is Absolute

The first law is simple: reserve funds must be completely separate from operating funds.

This means: - Different bank accounts (at minimum) - Different fund tracking in accounting - Different authority to spend - Different reporting to the board

Complete separation ensures that operating shortfalls cannot quietly consume reserve funds. When operating needs cash, the answer is never "just borrow from reserves." The answer is to address the operating budget.

How to verify: Can your accounting system show reserve balance independent of operating? Is there a distinct approval process for reserve expenditures? Are reserve bank accounts titled separately?

Law 2: Expenditures Match Components

Reserve funds are not a general savings account. They exist for specific purposes defined by your reserve study.

Each reserve study identifies components: - Roof: replace in 15 years, cost $200,000 - Painting: every 7 years, cost $50,000 - Pool equipment: replace in 10 years, cost $30,000

When you spend reserve money, it should match a component. A roof repair is a reserve expense. A landscaping bill is not.

How to verify: Can your accounting system track reserve expenditures by component? When you spend $20,000 from reserves, do you record which component it applied to? Can you show remaining funding per component?

Law 3: Funding Is Real-Time

Your reserve study says you are 85% funded. But that number is only as accurate as the data behind it.

If your reserve tracking is a spreadsheet updated quarterly, the actual percent funded might be 85%, 75%, or 95% depending on what has happened since the last update.

Real-time funding means: - Current reserve balance (from the ledger, right now) - Minus planned expenditures (what is committed) - Compared to current requirements (per reserve study) - Equals actual percent funded (as of this moment)

How to verify: When was your percent funded last calculated? Does it reflect all expenditures and deposits since the last reserve study? Can you see real-time percent funded?

Protecting reserves requires more than policies. It requires system architecture that makes violations difficult or impossible.

Architectural Pattern 1: Fund Isolation

Reserve funds are separate entities in the system, not just account labels: - Own balance sheet - Own transaction history - Own access controls - Cannot be accessed through operating transactions

The database enforces fund separation at the transaction level.

Architectural Pattern 2: Component Registry

The reserve study is encoded in the system: - Each component with useful life and replacement cost - Current funding allocation per component - Expenditure validation against registry

When you try to post a reserve expense, the system asks: which component? If the expense does not match a component, it is flagged for review.

Architectural Pattern 3: Continuous Calculation

Percent funded is not a stored value. It is computed:

Percent Funded = (Reserve Balance - Committed) / Fully Funded Balance

Every transaction that affects reserves immediately updates the calculation. There is no delay between activity and accurate funding status.

Architectural Pattern 4: Transfer Controls

Moving money between funds requires: - Explicit journal entries (not just bank transfers) - Board authorization documentation - Clear audit trail - Notification to relevant parties

Transfers cannot happen silently or implicitly.

Common Reserve Protection Failures

Failure 1: Commingled Accounts

Operating and reserve funds in the same bank account, "tracked separately in the books."

Risk: Anyone with check signing authority can spend reserves on anything. The accounting separation does not prevent the spending.

Failure 2: Untracked Expenditures

Reserve money is spent, but not tracked against specific components.

Risk: You know reserves went down, but not whether the spending matched the reserve plan. Components may be underfunded without visibility.

Failure 3: Stale Funding Data

The reserve study is updated annually. The reserve balance changes daily. But percent funded is only calculated when the study updates.

Risk: You are making decisions based on outdated information. The actual funding position might be materially different.

Failure 4: Informal Borrowing

Operating is short. The treasurer transfers money from reserves "temporarily." No board resolution. No repayment schedule. No documentation.

Risk: Temporary becomes permanent. The "loan" is forgotten. Reserves are depleted without visibility.

What Boards Should Require

  1. Separate bank accounts with reserve accounts clearly titled

  2. System-enforced separation between operating and reserve funds

  3. Component-level tracking of all reserve expenditures

  4. Real-time percent funded visible to the board anytime

  5. Documented transfers with board authorization required

  6. Regular review comparing actual expenditures to reserve study plan

The Cost of Unprotected Reserves

When reserves are not protected:

  • Special assessments become more likely (reserves spent on operating)
  • Reserve studies become inaccurate (actual spending diverges from plan)
  • Board liability increases (fiduciary duty to maintain reserves)
  • Property values suffer (buyers investigate reserve health)
  • Owner trust erodes (assessments despite "healthy reserves")

Protection is not bureaucracy. It is governance.
