| Decreases in the present value of defined benefit obligation or net defined benefit liability resulting from contributions by plan participants should be tagged with a positive value; increases in the present value of defined benefit obligation or net defined benefit liability resulting from contributions by plan participants should be tagged with a negative value. Increases in the fair value of plan assets resulting from contributions by plan participants represent a decrease in net defined benefit liability (equivalent to an increase in a net defined benefit asset) and should be tagged with a positive value. | en | http://www.xbrl.org/2003/role/commentaryGuidance | http://www.xbrl.org/2003/role/link |
