Utilizing a novel data collection technique using Amazon Mechanical Turk (MTurk), I collect non-GAAP earnings data from 2003 to 2012 and measure managers’ non-GAAP exclusions relative to three comparable earnings: (1) GAAP earnings before extraordinary items, (2) GAAP earnings from operations, and (3) analyst-adjusted “street earnings.” I find a negative association between the magnitude of managers’ non-GAAP exclusions and the extent to which current returns reflect future earnings information. Additional tests reveal this negative association is due to income-increasing exclusions. I find similar results using the association between current returns and either future earnings from operations or future non GAAP earnings. I also provide evidence of increased garbling of future earnings news when managers use incremental non GAAP exclusions to meet or beat the consensus earnings forecast. Finally, I find that consistent non-GAAP reporting is associated with more future earnings information reflected in current stock returns.Non-GAAP EarningsNon-GAAP ExclusionsFuture Earnings Response Coefficient (FERC)
