                      Appendix D  -  Analysis of Changes

The table below presents all line items from the ICR with a greater than 50 percent change (positive or negative) from the currently approved ICR (i.e., OMB's inventory). It also includes an explanation of the reason for the change and the quality assurance actions to verify the validity of these changes.
