When it comes to public sector pensions, North Dakota's system for its teachers is somewhat less well funded than the state's public employees system (75% funded in 2006 compared with 89% funded, respectively). The state has slipped in meeting its annual required contribution for both plans in recent years, paying only about two thirds of the amount in 2005 and again in 2006. The legislature took several actions in 2007 to improve the long-term funding status of the teachers' fund, however (see below). On the non-pensions side, North Dakota has a very modest bill coming due for retiree health benefits, and was one of only 13 states that had set aside any funds for its long-term obligation as of 2006.
