than defined benefit plans and fail to provide adequate funds to retirees. Deferred compensation and other supplemental income plans CalPERS is responsible for a deferred compensation retirement plan (457 plan) and two other plans to supplement income after retirement or permanent separation from State employment. As of December 2014: The CalPERS 457 Plan serves 27,526 participants and had $1.296 billion in assets. The Peace Officers' & Firefighters' Defined Contribution Plan had 33,128 participants and $497 million in assetsfunded by a State contribution of 2% of base pay. A member-funded Supplemental Contributions Program for 521 participants had $20.3 million in assets. Disability retirement and industrial disability retirement CalPERS offers two types of retirement benefits if a worker is disabled. In "industrial disability retirement," the "disability is due to a job-related injury or illness"; in contrast, "disability retirement" implies that the disability was not necessarily caused by employment. The specific benefits vary by employer, by the contract between CalPERS and the employer, and by the employee's occupation. Two major controversies have affected CalPERS' disability retirement and industrial disability retirement program over the years. First, in the mid-1990s and again in the mid-2000s there were concerns about inappropriate industrial disability retirement for public safety personnel, including: Some non-disabled persons fraudulently claim industrial disability retirement, such as "a 'disabled' highway patrol officer riding in a rodeo." Unfortunately, "state law forbids Calpers from requiring disabled retirees who are 50 or older to submit to another medical evaluation, even if there is evidence of possible fraud". "A series of bills that expanded eligibility for these medical pensions - and made it easier to get them" increased costs for state and local governments. The list of "disabilities automatically presumed to be job-related for public-safety workers" has grown to include diseases and conditions that may or may not be caused by employment, such as lower back pain, heart disease, cancer, syphilis, HIV, and mad cow disease. Retirees can receive two safety disability retirements for the same condition if they are covered by two separate pension systems. Because California law prevents light-duty assignments in the California Highway Patrol, some officers are "forced to retire against their will." Second, "a 1980 state law that tied public safety officers' disability benefits to the age at which they were hired" caused an age discrimination complaint with the Equal Employment Opportunity Commission (EEOC) in 1992 which eventually led to a 1995 class action
