A new audit report in Guam shows there is a widening financial gap between the government's retirement fund assets and its future liabilities to retired workers.
The report released by the Office of Public Accountability says the gap has grown to 1.64 billion US dollars, trippling the unfunded liability over the past 16 years.
The fund's investments did have some financial gains in 2012 due to rebounding financial markets.
But the report says the government's plan to pay off the liability in full over 20 years is one reason the gap has grown and as retirees are now likely to live longer, the 20 year target should be lengthened.
The fund managers say the unfunded liability is now so large that it simply cannot be ignored or put off for future generations to contend with.
