The document provides guidance on procedures for flagging and reporting data associated with various circumstances: data validation, submittal of information related to data, and/or request for special treatment accompanied by supporting documentation related to a special event or condition (SEC). Chapter 1 provides a brief history of SEC data flagging. Chapter 2 presents data usage, tests, and criteria used to determine if a data value can qualify for the attachment of a data flag. Chapter 3 provides information on procedures to be followed for flagging data and providing supporting documentation for flags. Appendix A provides an explanation of several categories of SEC that may be used to describe some types of circumstances affecting data values. Appendix B provides examples of events that should not be considered as SEC.
