Incremental Costs Under ASC 310-20: But-For Test and Amortization

Under ASC 310-20, incremental direct costs of originating a loan are deferred and recognized over the loan’s life rather than expensed as incurred, but only if they pass a strict “but-for” test: the cost had to result directly from a specific loan that actually closed. Everything else is a period expense. That single distinction drives the entire framework, and getting it wrong distorts both reported earnings and the carrying amount of the loan portfolio.

The But-For Test

The FFIEC defines incremental direct costs as those that “result directly from and are essential to the lending transaction and would not have been incurred by the lender had that lending transaction not occurred.”¹ If the bank would have spent that dollar whether or not a particular borrower walked in the door, the cost fails.

Two consequences follow. First, a loan officer’s base salary is not deferrable in its entirety, because the officer would have been on payroll anyway. Only the compensation tied to time actually spent originating a specific, successful loan qualifies. A third-party credit report fee for one applicant, by contrast, clearly passes: no application, no fee.

Second, the test requires a closing. If the borrower withdraws or the bank declines the application, no asset was created and there is nothing to defer against. Costs from failed originations are period expenses.

Costs That Qualify for Deferral

ASC 310-20-20 groups direct loan origination costs into two categories: third-party costs and internal labor tied to specific origination activities. Both must pass the but-for test, but the documentation burden differs sharply.

Third-Party Costs

Fees paid to outside parties for a specific loan are the easiest to identify: credit reports, appraisals, title searches, and recording fees for perfecting the lender’s lien. Each generates an invoice tied to a specific file, which makes the trail straightforward to defend in an audit.

Internal Labor Costs

Employee compensation is typically the largest piece of deferrable origination cost and the most contentious. Deferral is limited to the portion of total compensation and payroll-related benefits tied to time spent on five specific activities for a successfully closed loan:

Evaluating the borrower’s financial condition, including income, assets, debt ratios, and credit history.
Evaluating and recording collateral and security arrangements, including guarantees and liens.
Negotiating loan terms such as rate, structure, covenants, and repayment schedule.
Preparing and processing loan documents, including notes, security agreements, and required disclosures.
Closing the transaction: executing final documents and funding the loan.

“Compensation” here means fully loaded cost: salary, benefits, bonuses, and payroll-related fringe for the time spent on those activities.² If a loan officer costs $50 per hour loaded and spends six hours underwriting and closing a mortgage, $300 gets deferred. The other 34 hours that week spent on marketing calls, staff meetings, and pipeline management do not.

Costs That Do Not Qualify

Anything outside those two categories is a period expense. The items institutions most often try to defer incorrectly:

Advertising and solicitation. Marketing campaigns and lead generation may eventually produce loans, but they are not tied to a specific transaction.
Administrative overhead: rent, utilities, equipment depreciation, and office supplies.
Supervisory salaries for managers who oversee the lending function but do not personally perform origination activities on individual files.
Idle time and general training, even for employees whose primary role is lending.
Costs on failed originations, including third-party fees already paid and employee time spent, because no asset was created.

Institutions with high denial rates or heavy marketing spend cannot smooth those costs into the loan portfolio. They flow straight through the income statement.

Held for Investment, Held for Sale, or Fair Value

What happens to the deferred balance after closing depends on classification.

For loans held for investment, the net deferred amount (origination fees received minus direct origination costs incurred) is amortized over the loan’s life as a yield adjustment using the effective interest method. The goal is a constant effective yield on the net investment in the loan receivable.

For loans held for sale, the net deferred fees and costs are not amortized. They remain part of the loan’s amortized cost basis until sale, when they affect the gain or loss. There is no interest income stream to adjust because the lender does not intend to hold the loan long enough for period-by-period yield recognition to be meaningful.

If the lender has elected the fair value option, ASC 310-20 does not apply. Upfront origination fees and costs are recognized immediately in revenue or expense rather than deferred.³

How the Effective Interest Method Works

For held-for-investment loans, the deferred net fees or costs run off over the contractual life through the effective interest method. If a bank originates a $200,000 mortgage with $2,000 in net deferred costs after netting fees, the bank treats its investment as $202,000 for yield purposes. Each period, interest income is recognized at a constant effective rate applied to that adjusted balance, gradually amortizing the $2,000 over the loan’s term. The reported yield sits slightly below the loan’s stated rate, reflecting the true economic cost of putting the asset on the books.

Prepayments cannot be anticipated when calculating the effective yield on a single loan. The contractual payment terms control. Institutions holding a large number of similar loans may estimate prepayments if the timing and amounts are reasonably predictable; when actual prepayments differ from estimates, the effective yield is recalculated and the net investment adjusted through interest income.

Amortization pauses when a loan goes on nonaccrual. If the lender stops recognizing interest income because of collectibility concerns, the deferred net fees or costs also stop amortizing. They resume when the loan returns to accrual status.

Revolving Credit Arrangements

Lines of credit and other revolvers follow a different rule. Instead of the effective interest method, net deferred fees or costs on a revolving line are recognized straight-line over the period the line is active, assuming borrowings remain outstanding for the maximum contractual term.

If the agreement lets the borrower convert a revolving line into a term loan, the lender amortizes straight-line over the combined life of the revolving period and the term loan. Once conversion happens, the unamortized balance switches to the interest method for the remaining term loan period. If the line expires without conversion and all borrowings are repaid, any unamortized balance is recognized in income immediately.

One detail catches institutions off guard. Even if a revolving line sits unused for months, the deferred fees and costs continue to amortize as long as the borrower retains a contractual right to draw. The straight-line clock does not pause for inactivity.

Payoff, Sale, and Loan Modification

When a loan is paid off early or sold, any remaining unamortized net fees or costs are recognized immediately in income. Once the asset leaves the balance sheet, there is no basis for continued deferral.

Modifications and refinancings need more judgment. The question is whether the transaction is a continuation of the existing loan or, in substance, a new loan. The OCC’s Bank Accounting Advisory Series draws a practical line: if the maturity date functions as a repricing date and the bank does not charge a new fee, prepare new documentation, or perform a fresh credit review, the existing deferred amounts continue to amortize over a normal loan period for that type.⁴ If the bank does perform a full re-underwrite with new documentation and fees, the old loan has essentially been repaid; any remaining unamortized balance is recognized at that point, and new fees and costs on the replacement loan are deferred over the new term.

This is where institutions sometimes get aggressive, rolling old unamortized balances into new loans to avoid a current-period income hit. Auditors look for the pattern, and substance over form governs.

Standard Costing Instead of Time Tracking

Tracking actual hours on every file is expensive, especially for high-volume consumer lenders. ASC 310-20-25-8 allows standard costing when origination cost is similar across specific types of loans.² A bank that originates 5,000 auto loans a year with a substantially identical underwriting process can develop a standard cost per loan rather than logging hours on each file.

The standard has to be validated, not assumed. Institutions typically build it through process mapping (documenting every origination step for each loan type) combined with time studies that reconstruct how long each step takes. The per-loan estimate needs periodic testing against actual experience. Standard costing works well for commodity products and poorly for complex commercial deals where effort varies substantially from file to file.

Documenting the Payroll Portion

The documentation burden for deferred compensation is heavier than most institutions expect. Regulators and auditors want observable data, not allocation formulas.

One method that has survived SEC scrutiny uses two parallel tracks. The first is a process matrix: a checklist of every step involved in originating each loan type, developed through interviews with the people doing the work, identifying which steps apply across products and which are product-specific. The second reconstructs detailed time records for a representative period by reviewing emails, calendar entries, meeting notices, and file notes on a loan-by-loan basis. If the two tracks broadly corroborate each other, the standard hours are considered supportable.²

Beyond the time studies, contemporaneous records such as closing binders, borrower financial data, and closing memos help confirm the origination work actually happened. Validation should also confirm that non-origination activities (portfolio management, dead deal work, solicitation of new borrowers) have been excluded, and that the compensation rate reflects total loaded cost rather than base salary alone.

Where It Shows Up on the Balance Sheet

Unamortized deferred origination costs are not shown as a standalone asset. Net unamortized costs are added to the carrying amount of the related loans; net unamortized fees (where fees exceed costs) are deducted from loan balances in the same manner as unearned income.⁵

On regulatory call reports, net unamortized origination costs are added to loan balances in Schedule RC-C, Part I. The income effect from amortization is reported as an adjustment to interest income in Schedule RI, not as noninterest income or expense.⁵ Wrong line item placement is a common examination finding.

Commitment Fees

When a lender charges a commitment fee for agreeing to make a loan, the fee generally follows the same deferral framework. Direct origination costs are offset against the commitment fee, and the net amount is deferred. If the commitment is exercised and the loan funds, the net deferred balance is recognized over the loan’s life as a yield adjustment.⁵

Two exceptions apply. If the likelihood of exercise is remote, the net fee is recognized as service fee income on a straight-line basis over the commitment period rather than deferred into the loan. And retrospectively determined fees, where the amount is not known until a later date, are recognized in income when determined. Both exceptions flow to noninterest income, not interest income.
