As of March 31, 2019 and March 31, 2018, the Company had accrued interest and penalties related to tax contingencies of $88.1 million and $80.8 million, respectively. Interest and penalties charged to operations for the years ended March 31, 2018 and 2017 related to the Company's uncertain tax positions were $5.4 million and $5.8 million, respectively. Previously accrued interest and penalties that were released during the year ended March 31, 2019 were $37.5 million.
