Broken Date

Updated October 1, 2019

What is the Broken Date?

Broken dates are arbitrary maturity dates that do not necessarily match the duration of the bond, option, futures contract, forward contract or other maturing instrument. Broken dates are also known as odd dates.

How Does the Broken Date Work?

For example, let's assume that a futures contract for shares of Company XYZ is three months long and is issued on April 1. The regular maturity date would be 90 days later on July 1. However, if the contract has a broken date, it might mature on, June 28 or July 2. Likewise, its maturity could be in, say, 5 weeks when the typical date is 12 weeks.

Why Does the Broken Date Matter?

The finance world greatly relies on standardized maturities for specific contract types. This results in consistent recordkeeping and reporting for investors and the rest of the financial world, making trading easier and less costly. When a contract has broken date, it is something of a "rogue" investment and requires extra care from the implicated financial services firms and investors who hold the securities.
