members exceeded 1 million. Governor Gray Davis In 1999, fund value reached $159.1 billion, requiring $159 million in state tax dollar contributions. In 1999, the CalPERS board proposed a benefits expansion that would allow public employees to retire at age 55 and collect more than half their highest salary for life. CalPERS predicted the benefits would require no increase in the State's contributions by projecting an average annual return of 8.25% over the next decade. When Board member Phil Angelides’ aide questioned whether the stock market could grow that long, Board Chairman William Crist, a former union president, replied that they “could make all sorts of different assumptions and make predictions, but that’s really more than I think we can expect our staff to do.” CalPERS' chief actuary, objected, finding that it would be “fairly catastrophic” if the fund only grew at 4.4%. The benefits expansion bill, SB 400, passed with unanimous backing by California State Assembly Democrats and was signed into law by Governor Gray Davis. CalPERS then produced a video promoting the legislation with Chairman Crist promising greater benefits “without imposing any additional cost on the taxpayers” and the California State Employees Association president praising it as “the biggest thing since sliced bread”. The next year the dot-com bubble burst, and CalPERS did not grow, instead losing value in the stock market downturn of 2002. In 2001–2002, CalPERS provided technical assistance for the Sarbanes-Oxley Act because it had sustained financial losses from the Enron and WorldCom bankruptcies. After the Great Recession, in 2009 CalPERS investments lost 24%, dropping $67 billion in value. Chairman Crist retired from the board and it was later revealed he had accepted more than $800,000 from a firm to ensure hundreds of millions of investment from CalPERS. In November 2005, CalPERS expanded its headquarters with the "Lincoln Plaza East & West" buildings which cost $265 million. The architecture of the buildings, which received praise, includes an entry tower high in a shape reminiscent of a tree which is made of steel covered with glass. The project was awarded a Gold Leadership in Energy and Environmental Design (LEED) rating. Governor Jerry Brown In 2012, Governor Jerry Brown signed legislation that reduced benefits for all new state employees and sought to combat pension spiking. Legislators rejected Governor Brown's proposals to include a 401(k) type defined contribution plan and to require CalPERS Board members to be independent,
