SACRAMENTO, Calif. (AP) — The nation’s largest public employee pension system beat its investment earnings target last year for the second consecutive time.

The California Public Employees Retirement System reported a preliminary return Thursday of 8.6 percent for the fiscal year that ended June 30. That beats fund managers’ 7 percent target and avoids even higher costs to public employers.

CalPERS reported $351 billion in assets, enough to cover 71 percent of payments owed to its 1.9 million members. That’s up 3 percentage points from the previous fiscal year.

The gains were driven by double-digit returns in public and private equity markets.
