| PreviousDocumentation | A narrative description of investment policies and strategies, including target allocation percentages or range of percentages considering the major categories of plan assets as of the latest statement of financial position presented (on a weighted-average basis for employers with more than one plan), and other factors that are pertinent to an understanding of those policies and strategies such as investment goals, risk management practices, allowable and prohibited investment types including the use of derivatives, diversification, and the relationship between plan assets and benefit obligations. For investment funds disclosed as major categories, the narrative description would be expected to also include a description of the significant investment strategies of those funds. | http://fasb.org/srt/role/changeNote/changeNote |
