# What is MBL software? Member business lending, the cap, and what the software does about it

> MBL software means member business lending software: the systems a credit union uses to originate, underwrite and monitor business loans made to its members. Because member business lending sits under a statutory cap and NCUA supervision, the requirements differ from ordinary commercial lending software in two ways: concentration and cap reporting matter as much as underwriting, and examiner evidence has to be a product of the work rather than something assembled afterwards.

Three letters cause a surprising amount of trouble. Search for MBL software and most tools will offer bills of lading, laboratory equipment or app builders, because the acronym belongs to several industries and lending is not the one that wins. Inside a credit union it means one thing: member business lending, the business loans a credit union makes to its members, governed by rules that have no equivalent on the bank side. This piece explains what the software is for, why the cap changes the requirements, and where the whole vendor category currently falls short.

## What the software actually does

Strip away the branding and member business lending software does five jobs. It takes the application and the borrower's documents. It converts those documents into a standardized spread. It builds a view of whether the borrower and the guarantors can service the debt. It records the decision, the exceptions and the covenants. And it watches the credit after booking, so a covenant breach or a missing statement surfaces before it becomes a finding.

Very few products do all five. Most credit unions end up with a division of labour: a consumer origination system that can take a business application, a commercial platform or analyst toolkit that does the credit work, and a spreadsheet somewhere handling the part nobody sold them. Working out which of the five jobs is actually slow at your credit union is the whole evaluation, and it is worth doing before the first demo rather than during the third.

- Intake: application, borrower and guarantor documents, entity structure
- Spreading: business and personal returns and interim statements into a standard template
- Analysis: debt service coverage across entities and guarantors, ratios, benchmarks
- Decision record: risk rating, exceptions, approvals, covenants, the credit memo
- Monitoring: periodic statements, covenant tests, concentration and cap reporting

## The cap, in plain terms

Member business lending is capped. The limit is expressed two ways, as 1.75 times the credit union's net worth and as 12.25% of total assets, and it originates in the Credit Union Membership Access Act of 1998, the statute usually referred to by its bill number, H.R. 1151. Which formulation binds depends on the credit union's own numbers, and the operative rule text and your examiner are the authorities on how it applies to you. Nothing here is regulatory advice.

What matters for a software conversation is the consequence. A bank growing a commercial book worries about concentration policy. A credit union growing a member business book worries about concentration policy and about running out of headroom, which is a different problem with different tools. Two of them are ordinary: accurate categorisation of what counts toward the cap, and reporting that tells you how much room is left. One of them is structural: loan participations, where part of a loan is sold to another institution so the originating credit union keeps the relationship without consuming as much of its own capacity.

That is why participations are the single most useful thing to ask a vendor about, and why the answer across this entire category is currently the same. No vendor we reviewed publishes a cap calculation, and loan participation capability appears in none of their material. For a segment defined by a cap, that is a real gap, and it means the cap lives in your own reporting rather than in the lending system.

## NCUA Part 723 in plain terms

Part 723 of NCUA's rules (12 CFR Part 723, Member Business Loans; Commercial Lending) does two separate jobs, and its first section says so. It sets the policy and program requirements for a safe and sound commercial lending program, and it carries the statutory limit on member business loans from Section 107A of the Federal Credit Union Act. The two jobs use different definitions, which is where most of the confusion starts.

A commercial loan is a loan, line of credit or letter of credit for a commercial, industrial, agricultural or professional purpose (§ 723.2). The definition excludes, among other things, loans secured by 1- to 4-family residential property, loans fully secured by shares or deposits, loans secured by a vehicle manufactured for household use, and borrowing relationships whose balances plus unfunded commitments, less any share-secured portion, total under $50,000. A member business loan, the thing the cap counts, is a commercial loan less a further set of exclusions: loans fully insured or guaranteed by a government agency, non-member loans and participations bought from another lender, and loans fully secured by a 1- to 4-family dwelling (§ 723.8(b)). A business-purpose loan secured by a household vehicle runs the other way: it is not a commercial loan, but it counts toward the cap once the net balance reaches $50,000 (§ 723.8(c)).

The cap is the lesser of 1.75 times the credit union's actual net worth or 1.75 times the net worth it needs to be well capitalized (§ 723.8(a)). The Federal Credit Union Act sets well capitalized at a net worth ratio of at least 7 percent, which is why the second figure is usually quoted as 12.25% of total assets. Four kinds of credit union are exempt from the cap: those with a low-income designation, CDFI program participants, those chartered to make member business loans, and those with a history of primarily commercial lending when the Credit Union Membership Access Act passed in 1998 (§ 723.8(d)).

What gets measured against the cap is a net balance: outstanding balances plus unfunded commitments, less any portion secured by shares or deposits or by a lien on a member's primary residence, insured or guaranteed by a government agency, or sold as a participation without recourse that qualifies for true-sale accounting (§ 723.8(e)). That last item is why participations matter so much to a credit union near its limit, and NCUA's Examiner's Guide works through the same calculation in its Aggregate MBL Limit section.

The program requirements sit in §§ 723.3 and 723.4. Before making commercial loans, the board must approve a written commercial loan policy, review it at least annually, and see that the program is staffed with people experienced in underwriting, portfolio risk rating and collections. The policy must cover the loan types allowed, the trade area and a loans-to-one-borrower limit, among other items. That limit is the greater of 15% of net worth or $100,000 across a borrower and its associated borrowers, plus another 10% of net worth where the excess is fully secured by readily marketable collateral. A credit union under $250 million in assets whose commercial loans, including participations sold, stay under 15% of net worth is exempt from those two sections (§ 723.1(b)).

A state-chartered credit union may follow its state's rule instead where NCUA has found that rule no less restrictive (§ 723.10). This is a reading of the rule text, not regulatory advice; the eCFR text and your examiner settle how it applies to you.

- Classify every business loan twice: commercial loan under § 723.2 and member business loan under § 723.8
- Report the net member business loan balance as § 723.8(e) defines it, unfunded commitments included
- Track participations sold without recourse separately, because they leave the cap balance
- Aggregate exposure across associated borrowers before testing it against the loans-to-one-borrower limit
- Keep the board-approved policy, its annual review and every policy exception on file for the exam

## What Part 723 covers, and why it shows up in a software evaluation

NCUA Part 723 is the rule for member business loans. In practical terms it is where expectations about documentation, underwriting standards and portfolio concentration limits live, and it is the reason an examiner asks a credit union to show its work rather than describe its intentions. Read the rule itself for the mechanics; what follows is only how it lands on a technology decision.

It lands as an evidence requirement. An examiner reviewing a member business loan file wants to see how the numbers were derived, who reviewed them, which exceptions were identified and approved, and whether covenants have been tested since booking. Software either produces that as a by-product of the work or leaves your team assembling it after the fact, and the difference is a recurring internal cost that never appears in a licence comparison.

This is the criterion where the category divides most sharply, and not in the direction the market's recommendations suggest. Of the vendors in this segment, one states plainly that member business lending programs are regulated by the NCUA, which sets requirements for documentation, underwriting and portfolio concentration limits, and maps examination expectations to product features. One other explicitly scopes itself to smaller member business loans and treats auditor and examiner evidence as a named capability. The rest, including the largest and most frequently recommended platforms, address the regulator generically or not at all.

- Ask what the product produces without being asked, not what it can be configured to produce
- Look for a figure that traces back to the document and page it came from
- Look for an exception and covenant record that is a by-product of the credit work
- Ask who calculates the cap today, and confirm it is not assumed to be the software
- Treat an unverifiable claim about audit outcomes as worth nothing

## How this differs from commercial lending software generally

Most of the products a credit union will be shown were built for banks and adapted. That is not disqualifying, and several of them are the strongest options available. But the adaptation shows in specific places, and knowing where saves time.

Pricing is the clearest. A licence priced on total assets treats a credit union with a large balance sheet and a modest member business book like a commercial bank of the same size, which is the wrong shape entirely. At least one vendor in this market prices on the business lending portfolio and the number of users instead, and for a typical credit union program the two bases produce very different numbers for identical work.

Reference evidence is the other. Ask for a US credit union running the specific product for member business lending, ideally with the lending executive on the call. Bank references answer a different question, and in at least one case a vendor's named credit union references include institutions outside the United States and therefore outside NCUA supervision, which cannot tell you anything about Part 723 readiness.

| Requirement | Bank commercial lending | Credit union member business lending |
| --- | --- | --- |
| Growth ceiling | Concentration policy and appetite | Statutory cap, expressed against net worth and total assets |
| Managing headroom | Rarely a constraint | Participations, categorisation and cap reporting |
| Primary supervisor | Federal or state banking regulator | NCUA, with Part 723 for member business loans |
| Typical deal size | Wide range | Often smaller, member-scale business credits |
| Sensible pricing basis | Institution size is a fair proxy | Business lending portfolio, not total assets |
| Useful reference | A bank of similar size | A US credit union running the same product for MBL |

## Common questions

### Does a credit union need dedicated MBL software, or will the consumer system do?

For a handful of small, simple business loans a year, a consumer origination system that supports business lending as a loan type can be enough, because it takes the application and books the loan. Once files involve multiple entities, guarantors and covenants, the consumer system is the front door rather than the underwriting, and the credit work needs a commercial platform or an analyst toolkit behind it.

### Which vendors calculate the cap?

None that we could verify. Across every vendor page and filing read for this research, no product publishes a calculation against the 12.25% of assets or 1.75 times net worth tests, and loan participation capability appears nowhere. Ask each vendor directly and plan for the calculation to live in your own reporting.

### Is agricultural lending part of member business lending?

Farm credits are a substantial part of the member business book at many credit unions, and they need different handling: Schedule F income, commodity cycles and seasonal cash flow that an annual coverage ratio hides. Two vendors in this market cover agricultural credit analysis explicitly. If farm lending is real for you, test it on an actual file rather than accepting a loan type list.

### What should we ask about examiner evidence?

Ask to see the artifacts rather than hear about the posture: an audit trail for every loan, a spread figure clicked back to its source page, exception and tickler reports by officer, covenant tests recorded per period. Vendors that generate those automatically save you a recurring internal cost. Vendors that describe a compliance philosophy are describing your future workload.
