| New accounting pronouncement or change in accounting principle, description | On August 28, 2018, the FASB issued ASU 2018-13, Fair Value Measurement. This standard is effective for public business entities in fiscal years beginning after December 15, 2019, and for interim periods within those years. Early adoption is permitted, including during an interim period. This new standard requires changes to the disclosure requirements for fair value measurements for certain Level 3 items, and specifies that some of the changes must be applied prospectively, while others should be applied retrospectively. The Company is evaluating this new standard, but does not expect it to have a significant impact on its financial statement disclosures. | |
