Meaning and transaction use
NYSE's historical IPO case study describes using an order book and successive price indications to assess buy-side and sell-side interest before the opening trade. It identifies roles for the designated market maker, floor brokers and underwriter in that specific market process. [S1]
Proposed review method: assemble a price-and-quantity schedule that preserves each indication's conditions and timestamp. Separate the issuer's valuation analysis from observed investor demand. Review concentration, price sensitivity, order changes and any dependence on a small number of counterparties before recommending a pricing decision.
Worked example
Illustrative offering only. Assume 1 million shares are available and three investors provide non-binding maximum-price indications: A seeks 500,000 shares up to USD 10, B seeks 400,000 up to USD 9.50, and C seeks 300,000 up to USD 9. Assume no other demand, changes or allocation conditions.

| Test price | Eligible indicated demand | Demand coverage |
|---|---|---|
| USD 10.00 | 500,000 shares | 0.50x |
| USD 9.50 | 900,000 shares | 0.90x |
| USD 9.00 | 1,200,000 shares | 1.20x |
At USD 9, the assumed indications cover the offered quantity by 1.20x and imply USD 9 million gross proceeds if all 1 million shares are sold at that price. The indications remain non-binding; the calculation does not establish a clearing price, allocation or completed sale.
Proposed transaction review process
Define the price decision
Identify the security, quantity, process, proposed timetable and relevant market rules.
Capture qualified evidence
Record investor identity, price limit, quantity, conditions and timestamp.
Analyse sensitivity
Recalculate demand across prices and inspect concentration and conditional orders.
Document execution
Record pricing authority, final terms, allocations and subsequent settlement evidence.
Evidence checklist
Supply terms
Number of securities, primary or secondary split and any authorised flexibility.
Demand record
Dated indications or orders with price limits and explicit conditions.
Valuation support
Financial assumptions, comparable evidence and the rationale for the proposed range.
Decision trail
Changes to the book, pricing approvals, allocation records and settlement status.
Decision framework
| Situation | Proposed action |
|---|---|
| Demand disappears at a modest price increase | Assess price sensitivity and the issuer's minimum funding requirement. |
| One investor accounts for most of the book | Test the effect of withdrawal or reduced allocation on execution. |
| An order depends on an unresolved condition | Classify it separately and verify whether the condition can be satisfied. |
| Market conditions change before pricing | Refresh the evidence and approval analysis at the actual decision date. |
Common errors to check
- Adding indications that apply at incompatible prices.
- Counting the same investor through multiple intermediaries without reconciliation.
- Treating an oversubscription ratio as proof of settlement.
- Using an old indication after its conditions or validity have changed.
Review demand and execution assumptions
Bring the proposed size, valuation range and dated investor indications to a financing review. Assess price sensitivity and conditional demand before setting the execution recommendation.
