The BPC passed its first Daubert challenge in mid-December 2010 in Alamar Ranch, LLC v. County of Boise, a decision by the United States District Court (Idaho)(Civil Case No. 1:09-cv-00004 BLW).  In response to the challenge, Peter Butler (Valtrend) submitted an affidavit listing the numerous instances of independent peer comments, articles, speaking engagements as evidence of peer review.  In the Alamar Ranch case, trial testimony also highlighted positive endorsements of the BPC – some from Ph.D.s and finance professors - that recognize the model’s central technique stems from modern portfolio theory.
