The Pew Center has released its annual summary of US pension and retirement health care (under)funding. As of 2010, the total underfunding gap rose by $120 billion from the prior year's $1.26 trillion deficit to a record $1.38 trillion underfunding. This number consists of $757 billion in pension promises, not backed by any hard cash, representing pension liabilities of $3.07 trillion and assets of $2.31 trillion.
