FASB ASU 2025-08 Explained: Gross-Up Accounting for Purchased Seasoned Loans

Imagine you just closed on the acquisition of a small equipment-leasing company. Buried in the deal were a few hundred outstanding loans the seller had made to its customers over the years — completely current, no red flags, nothing that looked distressed. And yet, under the accounting rules that applied until now, your very first journal entry as the new owner could have included a chunk of loss on assets that hadn't lost a dollar of value. No missed payments. No red flags. Just a Day 1 hit to earnings that made a perfectly healthy loan portfolio look like a problem the moment you took ownership.

That quirk has puzzled bankers, credit unions, and anyone who acquires a business with loans or notes receivable on its books for years. In November 2025, the Financial Accounting Standards Board (FASB) finally did something about it with Accounting Standards Update (ASU) 2025-08, Financial Instruments—Credit Losses (Topic 326): Purchased Loans. If your business ever buys, merges with, or consolidates an entity that's carrying loans — think community banks, credit unions, buy-here-pay-here auto dealers, equipment financers, factoring companies, or any small business that extended seller financing to its own customers — this update is worth understanding before your next deal closes.

The Problem ASU 2025-08 Fixes​

Under the credit-losses standard (ASC 326, better known as CECL), acquired loans have always been split into two buckets:

• PCD loans ("purchased financial assets with credit deterioration") — loans that had already shown meaningful credit deterioration since origination. These got the "gross-up" treatment: the acquirer adds its estimate of expected credit losses to the purchase price to establish the loan's amortized cost basis. No day-one hit to the income statement.
• Non-PCD loans — everything else. These were accounted for as if the acquirer had originated them itself, which meant immediately expensing an allowance for credit losses through the income statement — even for loans that were performing perfectly well.

Stakeholders told FASB this distinction produced backwards results. A stack of clearly distressed loans (PCD) got favorable, no-day-one-loss treatment, while a stack of healthy, seasoned, on-time loans (non-PCD) triggered an immediate provision expense purely because of how they were classified — not because anything was actually wrong with them. FASB agreed the outcome was, in its own words, unintuitive, and set out to fix it.

What Changes: Meet "Purchased Seasoned Loans"​

ASU 2025-08 creates a new category — purchased seasoned loans (PSLs) — and extends the gross-up approach to cover them. A loan qualifies as "seasoned" if either of these is true:

1. It's a non-PCD loan acquired in a business combination. All non-PCD loans obtained through a business combination (excluding credit cards) are automatically treated as seasoned.
2. It's a non-PCD loan acquired through an asset acquisition or VIE consolidation, purchased at least 90 days after origination, by a party that wasn't involved in originating it.

In both cases, instead of recording an immediate credit-loss provision expense, the acquirer now records an allowance for expected credit losses by adding it to the purchase price, establishing the amortized cost basis up front — exactly the same mechanics banks already use for PCD loans. No provision expense. No misleading Day 1 loss on a loan that's performing exactly as expected.

What's excluded: credit cards, debt securities, and trade receivables accounted for under the revenue recognition standard (ASC 606) don't qualify as purchased seasoned loans, so they stay on their existing accounting treatment.

Why This Matters Beyond Big Banks​

It's easy to read "FASB," "CECL," and "PCD" and assume this is purely a large-bank issue. It isn't. Any business that ends up holding a portfolio of loans or notes receivable acquired from someone else can be affected:

• Community banks and credit unions doing whole-bank or branch acquisitions — the classic use case this rule was written for.
• Equipment finance and leasing companies that buy a book of leases or loans from another lessor.
• Buy-here-pay-here dealerships and other seller-finance businesses that acquire a competitor along with its outstanding customer notes.
• Factoring and specialty finance companies that purchase seasoned loan or receivable portfolios as part of a business combination.
• Any small business acquiring a company where seller financing, member loans, or installment receivables sit on the target's balance sheet.

If a deal you're doing — or advising on — involves loans that are more than 90 days old and you weren't the one who originated them, this rule change directly affects how you'll book that acquisition.

How the Gross-Up Mechanics Actually Work​

The core idea is simpler than the jargon suggests. Under the old non-PCD treatment, you'd record the loan at fair value, then separately book an allowance for expected credit losses as a Day 1 expense — a hit to earnings on the very day you closed the deal.

Under the gross-up approach that now extends to purchased seasoned loans:

1. Estimate the expected credit losses on the acquired loan pool, just as you would for PCD assets.
2. Add that estimate to the purchase price to determine the loan's initial amortized cost basis.
3. Record the corresponding allowance for credit losses on the balance sheet — but with no offsetting provision expense hitting the income statement at acquisition.

The economics haven't changed — you're still setting aside a reserve against expected losses. What's changed is where that reserve shows up: it's baked into the balance sheet at initial recognition rather than run through earnings as a Day 1 charge. That single shift removes the "unintuitive" outcome FASB was trying to fix, and it also means acquired seasoned loans and PCD loans will finally get consistent treatment, which should simplify how finance teams build their post-acquisition allowance roll-forward schedules.

One additional simplification worth flagging: for institutions that don't use a discounted cash flow model, the update allows measuring the allowance using the loan's amortized cost basis rather than unpaid principal balance — which makes it easier to pool acquired seasoned loans with originated loans for ongoing credit-loss estimation after the deal closes.

Effective Date and Transition​

• Effective date: Annual reporting periods beginning after December 15, 2026, including interim periods within those years. For most calendar-year entities, that means fiscal year 2027.
• Early adoption: Permitted for any interim or annual period for which financial statements haven't yet been issued.
• Transition: Prospective only — the ASU applies to loans acquired on or after your adoption date. There's no retrospective restatement of loans you already own, so past deals stay on the old accounting.

That prospective-only design is a relief for anyone worried about reworking historical acquisition entries, but it also means the timing of your next deal now matters more than it used to. Closing a loan-portfolio acquisition a few months before versus after your adoption date could produce meaningfully different Day 1 income statement impacts.

How to Get Ready Now​

You don't need to do anything today, but if there's an acquisition on your roadmap for 2026 or 2027, a little preparation goes a long way:

1. Identify which loan populations you (or a target) hold that could qualify as "seasoned." Anything acquired more than 90 days after origination, from a party you didn't originate alongside, is now in scope for gross-up treatment.
2. Update your acquisition due-diligence models. If your deal models still assume a Day 1 provision expense for non-PCD loans, they'll overstate the earnings hit of a pending deal once this standard applies.
3. Talk to your CECL or loan-accounting software vendor early. Several providers were still finalizing how their tools will classify and compute allowances for purchased seasoned loans as of this update's release — don't assume your existing spreadsheet or system already handles the new category correctly.
4. Revise your disclosure templates. Expect your allowance roll-forward tables to need a new line item for the initial allowance on purchased seasoned loans, mirroring how PCD loans are already disclosed.
5. Loop in your auditor before your next deal, not after. Classification calls — is this loan pool "seasoned" or not — are exactly the kind of judgment area where getting alignment with your auditor ahead of closing saves a lot of pain during the audit.

Keep Your Books Ready for Whatever the Deal Brings​

Acquisition accounting for loans has always been one of those areas where the rules can quietly shape how a deal looks on paper long after the economics are settled. Whether you're a community bank absorbing a branch, or a small business buyer inheriting a handful of customer notes, having clear, auditable records of exactly what you acquired and when makes it far easier to apply rules like this correctly — and to defend your numbers later.
