The REIS Standards are dependent on, and are intended to supplement (and in some cases clarify) but not replace, other
established standards from authorized bodies including but not limited to valuation standards established through Uniform Standards
of Professional Appraisal Practice (USPAP), accounting standards established by United States Generally Accepted Accounting
Principles (GAAP) and the performance measurement and reporting standards promulgated by the CFA Institute known as the Global
Investment Performance Standards (GIPS).  Collectively, these other established standards are referred to as the REIS Foundational
Standards.  The REIS Council and Board provide comments to relevant industry initiatives when public comments are sought by these
Foundational Standards bodies.
