Fair value guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers are defined as follows:

Tier
 
Description
Level 1
 
Defined as observable inputs such as quoted prices in active markets
 
 
 
Level 2
 
Defined as inputs other than quoted prices in active markets that are either directly or indirectly observable
 
 
 
Level 3
 
Defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions
