TRENTON - (AP) -- A report that documents New Jersey's poor track record at paying into its public pension system has been issued just as Gov. Chris Christie navigates his latest proposal through a hostile Legislature.

A new study from the National Association of State Retirement Administrators shows that from 2001-2013, New Jersey ranked last among states for making payments into its public pensions.

The report was sponsored by AARP. It shows New Jersey made 38 percent of the annually required contribution, far below the median of 95 percent.

Christie proposes making a $1.3 billion payment in 2016. But it's less than half of what he and lawmakers agreed to in 2011.

The proposal comes after a judge ruled Christie and lawmakers must pay almost $1.6 billion into the fund.

Christie appealed the decision.
