Vietnam’s copyright society reported a 24% rise in revenue for the first nine months of 2026, without corresponding figures for writer payments or revenue sources. That increase gives a catalogue buyer a question to investigate, not a percentage to add to a bid.
A purchase price pays for income the buyer expects to receive from particular rights. Society collections, platform subscriptions and permission records each describe a different part of the route to that income. A buyer who substitutes one for another can pay for growth that never reaches the catalogue.
Start with the payment, then trace it back
The Vietnamese Society for the Protection of Music Copyright’s reported increase measures money collected by the society. It does not measure what an individual writer received. The society has not disclosed matching payout or source figures for the period. A seller can reasonably point to the increase as a reason to examine demand for the rights. The buyer still needs the catalogue’s own payment history to establish a price.
That distinction should shape the order of diligence. First identify the rights being offered and the people entitled to their income. Then obtain the statements that show what those rights generated, what was paid and when the payment arrived. Match each receipt to the underlying work and income source before projecting it forward. A collection total is useful context for that exercise, but it cannot replace any of those entries.
The practical calculation is simple: start a forecast with receipts attributable to the catalogue, then test each reason those receipts might change. Applying a society-wide 24% increase to every work skips both attribution and payment. It assumes that the catalogue shares in the same sources of growth and that the extra collections become payable income in the same proportion. Neither step follows from the published collection figure.
Subscriber growth needs its own bridge to royalties
China presents a different version of the same pricing problem. NetEase says it has more subscribers who yield less on average, while Tencent no longer reports quarterly paying-user metrics. A rising subscriber count, where one is available, therefore says little on its own about the value of a specific catalogue. The amount generated per subscriber matters, and the catalogue’s share of listening matters after that.
For a buyer, the sequence runs from platform activity to the income credited to the rights, then to the amount actually received. Each step needs a record of its own. A platform’s revenue trend cannot establish the catalogue’s share. Nor can a change in subscriber numbers establish that its royalty rate or payment volume moved in the same direction.
This matters when a seller asks a buyer to pay today for expected growth. If the expectation rests on wider platform use, the buyer should ask which catalogue receipts have already moved and which have yet to do so. The answer belongs in the forecast. The seller’s case is stronger when it connects a proposed increase to payment statements for the rights on sale, rather than to a platform headline.
Price permission work separately from income
Music platforms and licensing services are testing ways to make catalogue permissions easier to identify and use through application programming interfaces (APIs). Clearer permission information can help a rights holder show which uses it can authorize. That is a useful acquisition task: an unclear mandate can delay a licensing decision even when a work has an audience.
Permission information and royalty income should occupy different lines in a buyer’s review. Confirming who can grant a licence establishes what the buyer may be able to sell. A payment statement establishes what the rights have earned. Better permission data can support future licensing work, but the buyer should put revenue from that work into the price only when its basis can be shown.
For an independent label preparing a catalogue for sale, the same separation makes negotiations more precise. Organize the rights and permissions so a buyer can check the scope of the sale. Organize receipts by work and source so the buyer can check the income. If a proposed use has no payment history, present it as a proposed use with a defined route to authorization, rather than folding it into existing earnings.
Put uncertain growth in the payment terms
A buyer and seller do not have to settle every growth claim in the upfront price. They can agree on a price supported by verified catalogue receipts and make an additional payment depend on future receipts from the same rights. That structure gives the seller a way to benefit if the expected income arrives, while keeping the initial valuation tied to cash the catalogue has demonstrated.
The agreement should make the measurement testable. In particular, both sides should specify:
- which works and rights count toward the additional payment;
- which receipts count and the period in which they must arrive;
- how payment statements will identify the relevant income; and
- when the buyer will calculate and pay any amount due.
Those terms are useful whether the growth argument begins with Vietnam’s 24% collection increase or changes in China’s subscription business. The decision rule is the same: use attributable receipts to support the upfront bid, and pay for additional income when the agreed rights produce it.
