New Accounting Standards Not Yet Adopted Statement of cash flows-restricted cash In November 2016, the Financial Accounting Standards Board (FASB) issued an amendment to existing guidance on the presentation and classification of restricted cash in the statement of cash flows. The amendment requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows.

Simplifying the test for goodwill impairment In January 2017, the FASB issued amended guidance that simplifies the test for goodwill impairment. The standard eliminates Step 2 from the goodwill impairment test. Under the amended guidance, an entity should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity will recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, but the loss cannot exceed the total amount of goodwill allocated to the reporting unit. The new guidance is effective for the Company's fiscal year that begins on November 1, 2020 and requires a prospective approach to adoption. Early adoption is permitted for interim or annual goodwill impairment tests.
