(a)During the quarter ended March 31, 2020, we recorded a cumulative adjustment of $1.2 million to reduce revenue within our other medical market to correct an error related to prior periods as a result of our determination that a portion of our sales being recognized over time needed to be recognized at a point in time. The adjustment included a reduction of the related cost of goods sold of $0.8 million and related impacts to reduce the contract asset and an increase to inventory. The adjustment was not material to our Consolidated Financial Statements for any quarterly or annual period.
