A music catalog is not valued solely on what the music earns. It is valued on what the owner can prove it earns.

That proof usually starts with royalty statements, contracts, and collection histories. Those records support either a multiple applied to normalized annual earnings or a forecast of future cash flows discounted to present value. If revenue is missing from the statements, a rate is wrong, or an account carries a recoupment balance nobody can support, the problem reaches past the next payment. It reaches the price of the rights themselves.

The effect runs in both directions. Missing income can understate catalog earnings; omitted royalty obligations can overstate what the label retains. Payment delays and collection uncertainty can affect cash flow and value even when both are properly recorded.

What So So Def alleged

On July 6, 2026, Jermaine Dupri and two So So Def entities sued Sony Music Entertainment in federal court in Manhattan. The complaint described a 32-year relationship under at least seven agreements, more than $200 million in gross revenue from recordings involving Xscape, Da Brat, Kris Kross, Usher, Mariah Carey, and others, and alleged harm of more than $18 million. It claimed more than $10 million in interest on top.

This was not a dispute about one missing payment. The plaintiffs alleged that royalties went unreported, that incorrect rates were applied, and that improper cross-collateralization of account balances alone cost them more than $2.9 million. The most striking allegation concerned Kris Kross: that producer and override royalties on the group's first two albums sat for more than 20 years in a separate accounting system the plaintiffs did not know existed, and that statements finally produced in 2023 and 2024 showed more than $33 million in foreign sales on that account.

Sony's response was brief. A spokesperson said the matter concerned a royalty accounting dispute the parties had been actively trying to resolve. On August 28, 2026, the plaintiffs voluntarily dismissed the case without prejudice, stating that the parties had resolved it. Sony never answered the complaint. No settlement terms were disclosed, and the allegations were not adjudicated.

That last point matters. The case is useful not because it proves anything about Sony, but because the complaint lays out how a royalty record and a catalog's real economics can come apart. Investigating that gap requires more than the final statement. An audit clause provides a contractual route to the records behind it; its value depends on what it lets the reviewer see.

Follow the royalty base

A royalty percentage means nothing until you know what it applies to. Fifty percent of the income a domestic company actually receives can be a fraction of fifty percent of what was collected overseas before affiliates, subpublishers, and distributors took their fees. The contract decides which base applies and which deductions are allowed.

Catalog valuation adds its own vocabulary. Net Publisher's Share, or NPS, is publishing income retained after the writer's share and other contractual participations. Net Label Share, or NLS, is the recording-side equivalent: income retained after artist royalties, producer royalties, and applicable costs. Neither is the same as an individual artist's or producer's royalty stream, and every transaction has to define the calculation it is using.

So the valuation effect depends on whose income is being measured. A producer royalty that was never recognized inflates a label's apparent catalog income until the obligation is recorded. Distributor income that was never recognized depresses it. Before anyone can say whether a catalog is undervalued or overvalued, they have to know whose money is missing and whose interest is being priced.

Four mechanisms that deserve scrutiny

The simplest failure is the one at the center of the So So Def complaint: income that never reached the participant's statement at all. The four mechanisms below show why checking that statement requires the contract and the underlying records. They are general diligence issues, not findings against Sony.

Intercompany pricing and affiliate deductions. Income often passes through an overseas affiliate before it reaches the company that calculates a participant's royalty, and an internal license fee or subpublisher commission may shrink the base along the way. Whether that is permitted depends on the agreement, and in particular on whether royalties are calculated on receipts at source or on domestic net receipts. In Ellington v. EMI Music, New York's highest court enforced a 1961 agreement that paid 50% of the net revenue "actually received" by the publisher from foreign publication, even though the foreign subpublishers taking their cut were by then EMI's own affiliates. The contract drew no line between affiliated and unaffiliated subpublishers, so the court would not draw one either. An unfavorable economic result can follow from perfectly enforceable language.

Sale versus license. Many older recording agreements pay one rate on records sold and a different, higher share on masters licensed to third parties. In F.B.T. Productions v. Aftermath Records, the Ninth Circuit held that permanent downloads and mastertones fell under the "Masters Licensed" provision of Eminem's agreements, which paid 50% of net receipts and applied notwithstanding the records-sold provision, because Aftermath had licensed the masters to iTunes and the carriers rather than sold records through them. The decision turned on the language and structure of those particular agreements. It did not create a general rule that digital income is licensed income, and every catalog has to be tested against its own contracts.

Recoupment and cross-collateralization. Recoupable advances and costs can absorb royalties before additional cash becomes payable. Where authorized, cross-collateralization allows one project's earnings to offset another project's balance. The contract determines which costs and accounts can be combined. The valuation question is which balances actually attach to the interest being sold, and when, if ever, cash becomes payable.

Digital advances, guarantees, and breakage. A streaming service's advance or minimum guarantee can exceed the royalties its actual usage would have generated. The difference is commonly called breakage, and contractual allocation rules determine whether participants share in it. The UK Competition and Markets Authority's 2022 market study reported that the major labels and some other music companies typically allocated such non-artist-specific revenue to artists in the evidence it reviewed. That does not settle any particular account. Diligence must establish whether the participant received the applicable allocation, whether the calculation was correct, and which periods it covered.

Earned, payable, and priced

The So So Def complaint supplies a concrete illustration of why these distinctions matter to a buyer. The plaintiffs alleged that their production-share account for Xscape's first two albums, both platinum releases, opened the period ending June 2020 roughly $1.53 million unrecouped, generated more than $1 million in royalties from 2020 through 2024, and paid nothing at all because of that balance.

Take those figures as alleged. A zero distribution does not make the underlying participation worthless. It means a buyer has to ask whether the balance is valid, how fast the account will recoup, and whether the future income transfers with the interest. If the balance is wrong, correcting it changes both the timing of cash and the value of the asset.

Sony's Legacy Unrecouped Balance Program adds a further wrinkle. Sony describes it as paying through go-forward earnings for qualifying legacy participants without modifying existing contracts. The complaint argued that So So Def's Xscape balances should have been eliminated under it. Whether an account qualifies for a voluntary pay-through policy and whether a contractual balance has been extinguished are different questions, and a diligence file needs to answer both.

Once entitlement is established, the arithmetic is simple. Suppose diligence verifies an additional $200,000 of sustainable annual cash flow belonging to the interest being sold. At an illustrative ten-times multiple, that correction implies $2 million of additional value with everything else held constant. The number is a hypothetical, not an appraisal of anyone's rights, but it shows how a reporting error compounds once it lands in the earnings base.

Two kinds of recovery

A recovery has two parts, and they deserve different treatment. Past underpayments and interest are a historical claim: real money, but nonrecurring. Corrected future royalties are an increase in recurring earnings. Applying a recurring-income multiple to the whole catch-up payment overstates the improvement.

Reservoir Media's own reporting shows the distinction in practice. In fiscal 2025 it recognized $823,000 of what it labeled "Recovery Income," its share of proceeds from underreported usage of acquired catalogs for periods before it owned them. Reservoir booked that amount in other income, outside revenue, and backed it out of Adjusted EBITDA. A separate royalty recovery from the same kind of underreporting went into recorded-music revenue, and Reservoir's next annual report noted that it did not recur. Reservoir kept the first recovery out of its adjusted operating results and flagged the second as a one-time item. In both cases the company distinguished catch-up proceeds from recurring earnings, which is exactly the distinction a buyer has to draw.

Uncertainty has its own price. A study of Royalty Exchange transactions by Sasha Stoikov and Ivan Kosyuk found that sellers' asking prices tracked discounted-cash-flow valuations of median-performing songs, while the best bids clustered near multiples justified by bottom-decile performance. The study measured buyer conservatism generally, not a discount for accounting errors specifically. But a buyer who cannot verify the income stream has every reason to bid toward the bottom of that range.

What makes an audit right usable

To support that diligence, an audit clause needs usable terms: access to source records and the licensing terms behind them, affiliate transactions, calculation files, and recoupment histories; a realistic audit window and objection deadline; record-retention obligations; auditor qualifications; confidentiality; and reimbursement of audit costs when an underpayment exceeds a threshold. Arnall Golden Gregory's 2025 guidance on audit clauses walks through a similar checklist for creators dealing with labels, publishers, and studios.

Two limits apply. An audit clause cannot create a royalty entitlement the contract never granted. And the absence of a clause does not always make a lawsuit the only path: access sometimes comes through cooperation or other contractual rights, and compulsory disclosure may run through litigation or arbitration. The objective is an enforceable route to enough evidence to test the calculation.

Audit before pricing

For an independent label preparing for financing or sale, the exposure sits on both sides of the ledger. Distributor or licensee income that was never recognized understates catalog earnings. Producer or artist obligations that were never recorded overstate what the label retains and create future claims. Even where both are properly booked, slow collection and disputed balances affect cash flow and value. Whether historical liabilities transfer depends on how the deal is structured, and buyers price them through adjustments, escrows, or indemnities when they cannot resolve them.

In transactional work, the diligence request list is where this becomes concrete. The work begins by reconciling three records:

  1. What the music earned.
  2. What the contract allocates to each party.
  3. What was reported, recouped, and paid.

An unpaid royalty, an unrecouped advance, and a recoverable underpayment look alike on a summary statement and behave very differently in a valuation. Calling all three "lost revenue" obscures what can actually be collected or priced.

At Cadence, our thesis is that this evidence should be organized before a dispute or a transaction forces someone to reconstruct it. Contracts connected to royalty calculations, and calculations connected to source reports and payment histories, give independent rights holders a firmer basis for collecting their income, meeting their own obligations, and explaining their earnings to investors.

A catalog's economic value depends on the cash flow its rights can generate. Its transaction price depends in part on what the records can substantiate. Revenue assurance is the work of closing that gap.
