As a participant in CORP as a Tier 1, 2 or 3 DB Memberbenefits that are available to you vary depending on your Membership Tier:

Increases for Tier 1, 2 and 3 DB Members

In accordance with Proposition 125 passed by the State of Arizona voters in November 2018, the Cost of Living Adjustment (COLA) increases for correction officer retirees and survivors will be determined based on the Consumer Price Index (CPI) for the metropolitan Phoenix-Mesa area for the calendar year ending prior to each July payout and will be capped at 2%.  Since this proposition became law, it overrides all prior increase calculation methods for correction officer retirees.  The law also stated that CORP must prefund this COLA, which meant that the first time that a COLA may be granted, could occur with the July 1, 2020 benefit check, contingent on the CPI.  The law also specified that the COLA will be prorated for members in their first year of retirement based on their retirement date.  

The following table provides examples of how the increase is calculated for members in their first year of retirement:

Example 1: Effective retirement date 7/1/2019

# of months retired: 12

Example 2: Effective retirement date 1/1/2020

# of months retired: 6

Example 3: Effective retirement date 6/1/2020

# of months retired 1

Example 4: Effective retirement date  7/1/2020
