Pension funds seriously underfunded, studies find

The L.A. Times reports:

Corporate and public pension funds across the country are seriously underfunded, threatening the retirement security of workers and straining the financial health of state and local governments, according to a pair of independent studies.

In 2011, company pensions and related benefits were underfunded by an estimated $578 billion, meaning they only had 70.5% of the money needed to meet retirement obligations, according to a report by S&P Dow Jones Indices.

Funds generally don't need to have all the money needed pay future pensions because returns on investments vary over the years and people retire at different ages and with different levels of benefits, experts said. But a funding level in the 70% zone is considered dangerously low.
