This paper examines analyst forecasting following the initiation of an accounting rule that changes how revenue is recognized within one industry. This new accounting rule was implemented in 2018 and will cause a significant change in how revenue is recognized. This paper seeks to understand the impact of this change on analyst forecasts and understand any potential difficulties or uncertainties it caused. Analysts were previously familiar with the legacy system for the respective firms they covered, and as such had an understanding of what a given period’s earnings would look like. After the implementation of this standard, analysts were forced to adjust and adapt to the new system of revenue recognition. The results show that the implementation of the new standard did have an effect on the analyst forecasts for the period after implementation.
