Defined Benefit Pension from law enforcement for a major city in Texas. The system has undergone multiple changes since inception (1940s), but at the time I retired at 45 I received 50% of regular pay (based on last paycheck) for the first 20 years of service, plus 2% for each subsequent year, plus the monthly average of all additional pay received over the last 12 months. It's COLAed at 75% of the local CPI capped with a floor and a ceiling.
The pension is a governmental subdivision of city government, but the elected officers are primarily current and retired employees, with representation from the Mayor and the City Controller. In other words, the political machinations from politicians is minimal and muted. The system is quite healthy, funded at about 85%, and would be better if previous city administrations had not created problems by taking funding holidays, and bribing active employees with manipulated pension increases in lieu of salary hikes.
The pension system sued the city over the underfunding and manipulations when a new mayor was elected. The lawsuit was settled by means of a contract between the city and the pension system that fixed some of the errors, reduced benefits for new hires, and allowed the city to spread out payments to fix the underfunding. The results is that there is still some drag on the city budget as a result, but the situation is much better than most other major cities in the country.
I was a participant in a DROP plan for 5 years before retiring, and that money was rolled over into a traditional IRA that I am not yet eligible to receive regular distributions from because of my age.
In addition, I started investing in the early 1980s and have a steady stream of income from the resulting portfolio.
