As Timothy Smith points out in the BVR/AHLA Guide to Healthcare Industry Compensation and Valuation, the preponderance of compensation data has made market-based approaches to healthcare compensation prevalent. Yet behind the apparent objectivity of these studies lie many nuances and considerations that could greatly affect the conclusion of value if not properly considered. In Critical Issues in the Use and Application of Market Survey Data and the Market Approach in Healthcare Compensation Valuation, Part 6 of BVR's 2013 Online Symposium on Healthcare Valuation, Smith will address what every appraiser needs to know when applying data from compensation surveys. As they say, the devil is in the details, and Smith's revelations about the makeup of market data will push appraisers to take a hard look at the basis of their market-based compensation assessments.
