Option Adjusted Spread (OAS)
Mainly used for fixed-income products, OAS measures the yield spread that is not directly attributable to the security's characteristics.

Investopedia Says:
This is a measurement tool for evaluating price differences between similar products with different embedded options. A larger OAS implies a greater return for greater risks.
