When-, As- and If-Issued Securities

Now that you understand standard settlement cycles, there's an important exception: securities that haven't been issued yet. These trade on a when-issued basis with no set settlement date.


When-Issued (WI) Trading

  • Securities trade on a when-issued basis before the actual issuance date
  • Common for:
    • New municipal bond issues
    • Stock splits
    • New corporate offerings
  • No accrued interest is calculated until the actual settlement date is established
  • WI trades have no set settlement date until the securities are actually issued
  • NYSE Rule 63 governs when-issued and when-distributed trading

Think of it this way: Buying a WI security is like pre-ordering a product that has not been manufactured yet. You agree on a price, but delivery (settlement) cannot happen until the product actually exists.


When-Issued Settlement Rules

  • Settlement occurs on a date determined after the actual issuance
  • If the issue is cancelled, all WI trades are cancelled
  • WI trades carry the risk that the security may never be issued
  • The settlement date is not known at the time of the trade; it is set only after the securities exist

Exam Tip: Gotchas

When-issued trades have NO settlement date at the time of the trade. Settlement is determined only after the securities are actually issued. If the exam asks "when does a when-issued municipal bond settle?" the answer is NOT T+1. It settles when the bonds are actually issued and a settlement date is established.


When-Distributed Securities

  • Similar to when-issued, but applies to securities that will be distributed as part of a:
    • Reorganization
    • Stock split
    • Spin-off
  • Trading occurs before the actual distribution date
  • Like when-issued securities, settlement happens after the distribution occurs

Exam Tip: Gotchas

If a when-issued bond offering is cancelled, all WI trades are cancelled and no obligation remains. Accrued interest on WI municipal bonds is not calculated until the settlement date is established.
