Depreciation Textbooks

Overview 

In 2018 the Society of Depreciation Professionals established the SDP Education Fund to support its mission as an educational institution.  The Fund aims to advance SDP's core objectives:

  • Promote the professional development and ethics of practitioners in the field of depreciation
  • Facilitate the exchange of information on depreciation engineering and analysis
  • Provide a national platform for programs and publications related to depreciation

 

Disclaimer

The opinions expressed in the books distributed through the Fund are solely those of the authors and do not necessarily represent the views of the SDP.

 

 

 

SDP Education Fund Publications

The Fund offers access to four foundational depreciation textbooks - long out of circulation but now available with permission from the original publishers.  These classic works are essential references for professionals in depreciation, valuation and utility regulation.
