Goodwill

For the first quarter ended March 31, 2019, our interim goodwill impairment tests indicated that goodwill for our North America reporting unit was impaired and as a result we incurred a goodwill impairment charge of $229 million. The impairment indicators during the quarter was a result of lower activity levels and lower exploration and production capital spending that resulted in a decline in drilling activity and forecasted growth in North America. Our cumulative impairment loss for goodwill was $2.9 billion at March 31, 2019. The changes in the carrying amount of goodwill by reporting segment at March 31, 2019, are presented in the following table.
