Member Business Lending: NCUA Part 723 Requirements

Member business lending is commercial lending done by a credit union, governed by NCUA rule 12 CFR Part 723. A member business loan is a loan made to a member for a commercial, industrial, agricultural or professional purpose rather than personal use, and once a borrower's aggregate commercial balance reaches $50,000 it counts against the credit union's MBL cap. That cap is the lesser of 1.75 times actual net worth or 1.75 times the minimum net worth required to be well capitalized. Since 2016 the rule has been principles-based: NCUA sets no prescriptive underwriting formula, so the quality of your commercial loan policy and the analysis behind each file is what the examiner tests.

This article covers what the rule actually requires, the exclusions most credit unions get wrong, what changed when the personal guarantee mandate went away, and what belongs in the credit file behind a member business loan.

What is a member business loan?

Part 723 draws a distinction that trips people up on first read. A commercial loan is any loan, line of credit or letter of credit, including unfunded commitments, extended to an individual, sole proprietorship, partnership, corporation or other business enterprise for a commercial, industrial, agricultural or professional purpose, and not for personal expenditure. A member business loan is the statutory category, drawn from the Federal Credit Union Act, that counts toward the aggregate cap.

The two overlap heavily but they are not identical. The clearest example is a vehicle manufactured for household use that a member buys through the credit union to run a business: the rule says that is not a commercial loan, but it is a member business loan once the aggregate balance reaches $50,000, so it counts against the cap without triggering the commercial underwriting requirements. The reverse case also exists, which is why credit unions with meaningful commercial books track the two populations separately.

What is the credit union member business lending cap?

The aggregate limit on a federally insured credit union's net member business loan balances is the lesser of 1.75 times its actual net worth, or 1.75 times the minimum net worth required under the Federal Credit Union Act to be well capitalized. For a well-capitalized credit union that works out to roughly 12.25% of total assets, which is the figure most people quote.

What matters day to day is the exclusions, because they create headroom a growing MBL shop can use:

The SBA point is the one worth internalizing. If a credit union originates a $1,000,000 SBA 7(a) loan with a 75% guaranty, only the $250,000 unguaranteed piece consumes cap. That is why SBA lending is the standard growth path for a credit union that is bumping against 1.75 times net worth, and why SBA loan underwriting software shows up on the shopping list at about the same time.

Do credit unions have to require a personal guarantee?

No. This is the change most people remember from the 2016 modernization, and it is still misunderstood.

The old rule required the personal guarantee of the principals on a member business loan and forced a credit union to apply to NCUA for a waiver to lend without one. The final rule eliminated the personal guarantee requirement in May 2016, with the bulk of the rule effective January 1, 2017, and eliminated the waiver process along with it. Any waiver NCUA had granted on commercial lending activity became moot as of that date, except waivers on borrowing relationship limits.

What replaced it is not permission to skip the guarantee. It is a documentation duty. If the credit union makes a commercial loan without the principals' personal guarantee, it has to document that mitigating factors offset the additional risk of not having it. That is an underwriting artifact and it lives in the credit memo. In practice the mitigants are stronger standalone business cash flow, lower loan-to-value on hard collateral, a tighter covenant package, or a shorter amortization. An examiner reading the file wants to see the analysis that supports the conclusion, not a sentence asserting it.

The broader shift is the important one. NCUA moved from prescriptive underwriting criteria written into the regulation to a principles-based standard, where the credit union writes a commercial loan policy appropriate to the size and complexity of its portfolio and then has to underwrite to it. Less regulation, more responsibility. The burden lands on the analysis.

What does a credit union commercial loan policy have to cover?

The rule expects a board-approved commercial loan policy scaled to the portfolio. The recurring elements across credit unions that examine well:

• The types of commercial loans permitted, the trade areas served, and the concentration limits by loan type, industry and borrower
• Loan approval authorities, from the individual analyst up to the board, with limits stated in dollars
• Underwriting standards and the required financial information, by loan size
• A credit risk rating system with defined grades and a process for assigning and re-testing ratings
• Collateral requirements, appraisal and evaluation standards, and loan-to-value limits
• The documentation required when a loan is made without a personal guarantee
• Periodic review of the portfolio and of individual credits, independent of the lending function

Credit unions with a commercial portfolio also need staff with commercial lending experience, either employed or contracted. NCUA does not prescribe a headcount, but a credit union running a $60 million commercial book on one analyst who came up through indirect auto lending is a finding waiting to happen.

What documents does a member business loan file need?

Nothing in Part 723 lists the documents, which is exactly the point of a principles-based rule. In practice a credit union's own policy converges on the same package a community bank uses:

• Business tax returns, two to three years, with all schedules and K-1s
• Interim financial statements, a balance sheet and income statement current to within 90 days
• A business debt schedule, which you should treat as a claim rather than a fact
• Operating account bank statements, three to twelve months
• Personal tax returns and a personal financial statement for each meaningful guarantor
• Entity documents, collateral documentation and appraisals where the loan is secured
• A credit report on the business and the principals

The debt schedule deserves the skepticism. It is self-reported and often months stale, and the recurring debits in the operating account are the record of what the member actually pays. Reconciling one against the other regularly surfaces a second lease, a merchant advance or a term loan that never made the schedule, and that discovery is frequently what moves a 1.35x coverage down to something the committee would not have approved. Where the member's books live in accounting software, a clean export helps, and where they do not, the raw statements are the only honest source. Many small business members hand over a stack of PDFs, and getting those into QuickBooks is often the first thing their bookkeeper does anyway.

How do you calculate cash flow on a member business loan?

Start from the business return. Take net income, add back interest, depreciation, amortization and any non-recurring items, and adjust owner compensation to a market rate if the owner is paying themselves above or below one. That gives cash flow available for debt service. Divide it by total annual debt service, including the proposed payment and every existing obligation, to get the debt service coverage ratio. Most credit union commercial loan policies want 1.20x to 1.25x, with the exact floor set by policy and by collateral type.

Where a guarantor's support is material, and in a closely held business it almost always is, the analysis has to widen. Global cash flow analysis combines the business cash flow with each guarantor's personal income, less living expenses and personal debt service, and with any affiliated entities the owners control, netting out distributions so the same dollar is not counted twice. The result is a global DSCR that tells you whether the whole borrowing relationship covers the whole obligation. On an SBA file the SOP requires this analysis on every owner of 20% or more. On a conventional member business loan it is your policy that requires it, and it is the number the credit committee should be looking at.

How is member business lending different from bank commercial lending?

Mechanically, barely at all. A credit union spreads the same returns, computes the same coverage, assigns a risk rating on the same kind of scale and writes the same style of credit memo. The differences are structural rather than analytical:

The staffing row is where the real constraint sits. A credit union growing member business lending usually adds volume faster than it adds analysts, and the first thing to break is the time available to spread financials properly. That is a solvable problem: the spreading, the ratio math and the global cash flow consolidation are mechanical, and underwriting software for credit unions can produce them from the source documents while the analyst keeps the risk rating and the credit judgment.

How often does a member business loan have to be reviewed?

Part 723 requires ongoing credit risk review appropriate to the portfolio rather than a fixed calendar, so the frequency comes from your own policy. The common pattern is an annual review of every commercial relationship above a dollar threshold, more frequent review of watch-list and criticized credits, and an independent loan review function or outsourced firm covering a risk-based sample of the book each year. The reviewer re-spreads the latest financials, recomputes coverage, tests covenant compliance and re-tests the risk rating. Our commercial loan review checklist walks through the items in order, and the annual review process covers the cadence.

Can member business lending underwriting be automated?

The document work can, and that is most of the elapsed time. Software reads the business returns, the personal 1040s and K-1s, the interim financials, the debt schedule and the bank statements, extracts every line item and computes the spread, the DSCR and the global cash flow, with each figure traceable back to the page it came from. What stays with the credit union is everything that requires judgment: the risk rating, the structure, the collateral view, the mitigating-factors analysis when there is no personal guarantee, and the decision itself.

That division is worth being clear about, because the vendor market is not. A loan origination system runs the pipeline and the approvals. A core system holds the member and the booked loan. Neither reads an 1120S and tells you the add-back adjusted cash flow. If your analyst is keying tax returns into a workbook, no amount of origination workflow fixes it. Start with the layer that reads the documents, then decide whether the volume justifies the rest.

Where credit unions should start

If member business lending is growing faster than your analyst headcount, the highest-leverage change is not a new policy or a new platform. It is removing the two hours of data entry that sit underneath every commercial file. Get the spreading automated, keep the judgment, and make the credit memo defensible enough that an examiner reading it can follow the analysis from the source document to the rating. Everything else in Part 723 follows from having done the work.
