The guidance is effective for public business entities in fiscal years beginning after December 15, 2018. The Company expects that this standard will have a material effect on its financial statements. While the Company continues to assess all of the effects of adoption, the Company currently believes the most significant effects relate to the recognition of new ROU assets and lease liabilities on its balance sheet for its Taiwan branch.
