The Cooperative Principle

Credit unions are financial cooperatives — democratic, member-owned institutions governed by the principle of "one member, one vote." Every person who holds an account is an equal owner with the same voting rights regardless of account size. This structure aligns the institution's interests with its members rather than with outside shareholders seeking maximum profit.

Governance: The Board of Directors

Credit unions are governed by a volunteer board of directors elected by the membership. Board members are unpaid (or receive only nominal compensation), are typically members themselves, and may include your neighbors, coworkers, and community leaders. The board sets policy, hires the CEO, and approves major financial decisions. Annual elections are open to all members, and any member in good standing may run for a board seat.

Supervisory Committee

Federal credit unions are required to have a supervisory committee — a volunteer body that acts as an independent audit committee. The supervisory committee oversees financial reporting, reviews internal controls, and ensures the board and management act in members' best interests. This additional layer of accountability is unique to credit unions.

How Profits Are Returned to Members

Because credit unions are not-for-profit (though they do aim to generate surplus revenue), earnings are returned to members in three ways:

  • Higher dividend rates: More competitive yields on savings, certificates, and money market accounts.
  • Lower loan rates: Reduced interest rates on auto loans, mortgages, credit cards, and personal loans.
  • Fewer and lower fees: Reduced or eliminated maintenance fees, overdraft fees, and ATM surcharges.

Retained Earnings and Net Worth

Credit unions cannot issue stock to raise capital. They build their equity base (net worth) exclusively through retained earnings over time. This is why the net worth ratio is so important — it represents the institution's entire self-generated financial cushion accumulated over decades of operation.

Common Bond: The Community Requirement

Historically, federal law required credit unions to have a "common bond" — a shared characteristic that defined eligible members (same employer, same association, same neighborhood). This requirement still exists but has been broadened significantly. Community charters now allow credit unions to serve anyone in a defined geographic area, making it easy for most Americans to qualify for at least one credit union.

The NCUA as Regulator

The NCUA examines federally insured credit unions at least annually, reviewing capital adequacy, asset quality, management, earnings, liquidity, and sensitivity to market risk (the CAMELS framework). Examination findings can trigger supervisory action requiring management changes, capital restoration plans, or operational restrictions.
