Pricing Unclaimed Property Risk in Acquisition Due Diligence

• Unclaimed property liability attaches to the holder and generally transfers with the company in a stock acquisition.
• Unreported property accrues interest at 12 per cent per annum under CCP §1577 unless reasonable cause applies.
• The Voluntary Compliance Program waives that interest for a holder that completes it, and it runs year-round, making it available before closing.
• A target can simultaneously be a holder that owes unclaimed property and an owner of unclaimed property it has never claimed.
• Filing deadlines differ by industry: most businesses file before 1 November and remit between 1 and 15 June.

Why does unclaimed property belong in an acquisition due diligence checklist?

Most due diligence checklists cover accounts receivable, tax exposure, pending litigation and employee benefits. Unclaimed property rarely makes the list, and that is a gap worth closing. If the target company has ever issued a payroll check nobody cashed, held a customer credit nobody claimed, or administered a benefit plan with a lost beneficiary, it has an unclaimed property reporting obligation under California law, and that obligation does not disappear when the company changes hands. It transfers with the entity, along with any interest already accruing on what was never reported.

This matters most in a stock purchase, where the acquirer steps into the target’s existing liabilities rather than selecting which ones to assume. It can matter in an asset purchase too, depending on how the deal is structured, which is a question for transaction counsel, not for this article. Either way, the number a buyer should want before signing is not whether the target has an unclaimed property policy, but how much exposure exists and since when.

What liability actually transfers with the company?

California requires most businesses to report unclaimed property, including uncashed checks, dormant accounts, unclaimed refunds and unpaid benefits, to the State Controller on a fixed annual cycle. All other businesses file a notice report before 1 November each year and remit the property between 1 and 15 June of the following year; life insurance companies work to a different calendar, filing before 1 May and remitting between 1 and 15 December (State Controller, holder reporting). A target that has missed those windows, or never reported at all, owes more than the underlying property.

Under Code of Civil Procedure §1577, a holder that fails to report, pay or deliver property on time owes the Controller interest at 12 per cent per annum from the date it should have been reported, unless the failure was due to reasonable cause. That interest compounds quietly inside a company no one has audited for this specific obligation, and it is a liability the buyer inherits along with everything else on the balance sheet.

How large can unclaimed property exposure actually be?

There is no way to size a specific target’s exposure without examining its own records, but the scale of what California businesses report generally shows where exposure tends to accumulate. Across the State’s reported holder data, checking accounts alone account for 396,236 records worth $1,075,997,337, cashier’s checks account for 688,548 records worth $797,643,439, and proceeds due beneficiaries, the category that includes unpaid insurance and benefit claims, account for 233,994 records worth $944,161,281. These are exactly the categories a payroll system, a vendor-payment process or a benefits administrator generates routinely, and they are the categories most likely to sit unreported inside a company that has never been audited for compliance.

More than 2,199 companies have each reported 750 or more records to the State Controller, which gives some sense of how ordinary a reporting history is for a business of any meaningful size, and how conspicuous its absence is in a target that has none.

Could the target company be owed unclaimed property instead of owing it?

Yes, and a complete review checks both directions. A business is a legal owner in its own right: old deposits, matured investments, insurance proceeds or an uncollected vendor refund can sit unclaimed under its own name, exactly as they would under an individual’s. We index 14,775,153 property records reported to the State Controller, and some portion of any large company’s own history is realistically sitting in that file as an asset rather than a liability. It costs nothing to search here under the target’s legal name and any prior names before signing. For a company acting as claimant rather than holder, the process is the same one we describe for claiming for a business.

What belongs in a pre-close unclaimed property review?

A useful review checks three things against an outside standard, not against what the target’s finance team volunteers. First, filing history: did the company file its notice reports by the statutory deadlines, and did it remit within the statutory windows. Second, categories at risk: payroll, accounts payable, customer refunds and benefit or insurance proceeds, the categories that show up largest in the State’s own holder data. Third, whether any exposure found can be resolved through the Voluntary Compliance Program, which the Controller runs year-round and which waives the 12 per cent interest for a holder that completes it, an option that reduces the number a buyer has to price when exercised before closing, rather than after, when it becomes the buyer’s problem to fix.

California Unclaimed Property Services conducts this kind of review as a business escheatment audit, separate from our individual recovery work, for buyers and holders who need a defensible number before it becomes contractual.
