Rights Offerings: Subscription Rights, TERP, Dilution, and Execution

Analyze a rights offering as an expiring security and financing transaction: map entitlement and deadlines, calculate theoretical value and ownership dilution, model oversubscription and net proceeds, and verify settlement, tax, and backstop terms.

Direct answer

A rights offering distributes an expiring subscription entitlement to eligible holders, usually in proportion to shares held on a specified record date. The right, the newly subscribed share, and the existing share are distinct securities or settlement positions. A right does not become a share unless valid instructions and cleared funds reach the subscription agent through the required custody chain before the applicable deadline.

Terms are deal-specific. Rights can be transferable and trade separately, or nontransferable and lapse unused. A basic subscription privilege may be supplemented by an oversubscription privilege, subject to availability and proration, and by a standby or backstop commitment. The offering document, exchange notice, subscription agent, and broker instructions control; a theoretical ex-rights price is not a quoted price, fairness opinion, or guaranteed profit.

Mechanism and measurement

Freeze the security and holder perimeter. Identify the issuer, share class, record holder, beneficial owner, record date, entitlement ratio, fractional-right treatment, and excluded jurisdictions. Street-name holders normally act through a broker or custodian rather than directly through the subscription agent.
Map the three instruments. Record the existing share, each subscription right and any rights ticker, and the new share or unit delivered after closing. State whether the rights are transferable, when rights trading ends, how many rights are required per new security, and whether purchases of rights settle soon enough to exercise.
Build the event clock. Separate announcement, registration effectiveness, record, ex-rights, distribution, rights-trading cutoff, broker instruction, issuer expiration, withdrawal or extension, funding, allocation, refund, and new-share delivery dates. FINRA Rule 11140 governs the designated ex-rights date for covered U.S. transactions; do not infer it from the record date alone.
Read allocation conditions. Distinguish the basic privilege from oversubscription, whether full basic exercise is required, the proration base, ownership caps, minimum proceeds or participation conditions, standby purchases, dealer-manager fees, and the issuer’s rights to amend, extend, or cancel.
Measure value and ownership on one basis. For a new shares offered for each b old shares, subscription price S, and cum-rights price P_cum, the simplified theoretical ex-rights price is TERP = (b × P_cum + a × S) ÷ (a + b). The theoretical value distributed per old share is P_cum − TERP; the value per right depends on the rights issued per old share and rights needed per new share.
Bridge financing to claims and earnings. Calculate gross proceeds = new shares × S, then subtract fees and expenses for net cash. Reconcile post-offering basic and fully diluted shares, ownership, voting control, debt repayment, interest savings, taxes, backstop warrants, and weighted-average EPS timing without counting proceeds twice.
Verify completion and tax records. Reconcile accepted subscriptions, proration, refunds, securities delivered, final proceeds, fees, and use of cash in subsequent filings. Preserve the rights distribution and exercise records: U.S. tax basis can require allocation between old shares and nontaxable rights, while other jurisdictions and account types can differ.

The TERP equation assumes full subscription, immediate addition of subscription proceeds to company value, no fees or taxes, no information effect, and no change in operating value. If the market reprices distress, control, financing risk, or the use of proceeds, actual share and rights prices can diverge materially. For a holder with h old shares out of N, nonparticipation after M new shares are issued changes ownership from h ÷ N to h ÷ (N + M). Pro-rata exercise can approximately preserve ownership, but it requires new capital and does not eliminate price or business risk.

Worked examples

TERP and right value: Four old shares permit one new share at $8 while the cum-rights share price is $10. TERP = (4 × $10 + 1 × $8) ÷ 5 = $9.60. The theoretical value distributed per old share is $10 − $9.60 = $0.40; four rights are theoretically worth $1.60, which also equals $9.60 − $8. These are mechanical values before fees, taxes, timing, and market repricing.
Ownership and proceeds: A company with 100m old shares offers 25m new shares at $8. Gross proceeds are $200m; with $15m of fees, net proceeds are $185m, and post-offering shares are 125m before other dilution. A holder of 1m shares owns 1.0000%; without participation the stake becomes 1m ÷ 125m = 0.8000%. Exercising the pro-rata entitlement of 250,000 shares costs $2m and produces 1.25m ÷ 125m = 1.0000%.
Oversubscription and refund: Assume 25m shares are offered, basic subscriptions consume 20m, and valid oversubscription requests total 12.5m. If the document uses simple pro-rata allocation, the fill factor is 5m ÷ 12.5m = 40.0000%. A request for 100,000 extra shares receives 40,000; at $8, the unused funding refund is 60,000 × $8 = $480,000. Actual priority, caps, rounding, and proration can differ.
EPS and use of proceeds: Before the offer, net income is $50m and shares are 100m, so EPS is $0.50. Suppose the company issues 25m shares, uses $150m to repay debt costing 8%, and has a 25% tax rate. Simplified after-tax interest savings are $150m × 8% × (1 − 25%) = $9m; full-year pro forma net income is $59m and EPS is $59m ÷ 125m = $0.4720, still below $0.50. Actual EPS uses weighted-average timing and must incorporate the remaining cash, fees, operating effects, and diluted securities.

Risks and verification checklist

Obtain the final registration statement, prospectus or offering memorandum, supplements, amendments, and issuer FAQs; do not rely on a press-release summary.
Confirm the exact eligible security, record-holder and beneficial-owner treatment, record date, and any lending, short-sale, or unsettled-trade consequences.
Record rights issued per old share, rights required per new share, subscription price and currency, unit components, and fractional-right treatment.
Distinguish transferable from nontransferable rights; for transferable rights, verify symbol, venue, liquidity, price increment, and whether trading can be halted.
Use the officially designated ex-rights date and applicable exchange or FINRA notice rather than deriving it mechanically from the record date.
Test whether a purchase of rights can settle and be delivered through the custody chain before exercise; standard T+1 share settlement does not override a special event deadline.
Separate the rights-trading cutoff, broker or custodian instruction cutoff, payment cutoff, issuer expiration, and subscription-agent receipt standard.
Confirm acceptable instruction forms, currency conversion, cleared-funds rules, account restrictions, and whether instructions are irrevocable.
Check treatment of foreign holders, sanctioned or excluded jurisdictions, ADRs, multiple share classes, employee plans, and nominees.
Read basic-subscription eligibility and whether full exercise is required before requesting oversubscription.
Read the oversubscription allocation base, caps, rounding, priority, proration, funding amount, interest treatment, and refund timing.
Identify minimum-subscription or minimum-proceeds conditions, withdrawal rights, extensions, repricing rights, termination events, and cancellation refunds.
Quantify standby or backstop commitments, dealer-manager and subscription-agent fees, warrants, indemnities, related parties, ownership caps, and control effects.
Reconcile authorized, issued, treasury, outstanding, basic weighted-average, and fully diluted shares; do not treat them as interchangeable denominators.
Calculate gross proceeds, fees, net proceeds, debt repayment, remaining liquidity, cash runway, and any restricted use of proceeds.
Model EPS and cash flow with financing timing, taxes, avoided interest, foregone cash yield, operating use, dilution, and backstop securities.
Stress the share price below the subscription price and allow for rights-price decay, illiquidity, partial fills, failed delivery, cancellation, and delayed new-share trading.
Evaluate whether repeated financing, distress, related-party support, or a deep discount changes business value rather than merely redistributing theoretical value.
Obtain tax advice for basis allocation, sale, exercise, expiration, withholding, foreign tax, and account-specific treatment; IRS Publication 550 is U.S. general guidance, not a universal rule.
After closing, match accepted shares, refunds, net proceeds, debt changes, ownership, and use of proceeds to transfer-agent records and later SEC filings.

Common misconceptions

“A right is already a new share.” It is a separate, expiring entitlement that must be validly exercised and settled.
“A discount creates free value.” The cum-rights price normally contains the entitlement, while TERP and the rights price can change with new information and market conditions.
“The record date tells me the ex-date and last action date.” Ex-rights designation, rights trading, broker instructions, and issuer expiration are distinct events.
“Pro-rata exercise prevents every kind of dilution.” It can preserve percentage ownership, but not necessarily EPS, fully diluted ownership, value, control, or economic risk.
“An oversubscription request will be filled.” It is contingent on unused basic rights and the document’s eligibility, caps, proration, and closing conditions.
