We are currently evaluating the change in the effective date on our implementation efforts. We have started our implementation efforts and we are evaluating the method of adoption and impact of the standard on our reported consolidated financial condition, results of operations, cash flows and required disclosures. The adoption of this standard is expected to have a significant impact on our consolidated financial condition, results of operations, cash flows and required disclosures, as well as systems, processes and controls.</span></p><p style="margin-top: 9.00pt; line-height: 13.00pt; margin-bottom: 3.00pt; text-align: left"><span style="color: #001871; font-family: 'Arial', 'sans-serif'; font-weight: bold; font-size: 10.00pt">Income Tax</span></p><p style="margin-top: 0; line-height: 12.00pt; margin-bottom: 6.00pt; text-align: left"><span style="font-family: 'Arial', 'sans-serif'; font-size: 9.00pt">On December 18, 2019, the FASB issued an accounting standard that simplifies the accounting for income taxes by eliminating certain exceptions to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The amendments also simplified other areas including the accounting for franchise taxes and enacted tax laws or rates, and clarified the accounting for transactions that result in the step-up in the tax basis of goodwill. The standard is effective on January 1, 2021, with early adoption permitted. We do not expect the impact of the standard to be material to our consolidated financial condition, results of operations and cash flows.</span></p><p style="margin-top: 9.00pt; line-height: 13.00pt; margin-bottom: 3.00pt; text-align: left"><span style="color: #001871; font-family: 'Arial', 'sans-serif'; font-weight: bold; font-size: 10.00pt">Reference Rate Reform</span></p><p style="margin-top: 0; line-height: 12.00pt; margin-bottom: 6.00pt; text-align: left"><span style="font-family: 'Arial', 'sans-serif'; font-size: 9.00pt">On March 12, 2020, the FASB issued an accounting standard that provides temporary optional guidance to ease the potential burden in accounting for reference rate reform.

The previously issued standard provides that such equity securities could be measured at cost, minus impairment, if any, unless an observable transaction for an identical or similar security occurs (measurement alternative). The new standard clarifies that a company should consider observable transactions that require the company to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with the equity method immediately before applying or upon discontinuing the equity method.</span></p><p style="margin-top: 0; line-height: 12.00pt; margin-bottom: 6.00pt; text-align: left"><span style="font-family: 'Arial', 'sans-serif'; font-size: 9.00pt">The standard further clarifies that, when determining the accounting for certain forward contracts and purchased options a company should not consider, whether upon settlement or exercise, if the underlying securities would be accounted for under the equity method or fair value option.</span></p><p style="margin-top: 0; line-height: 12.00pt; margin-bottom: 6.00pt; text-align: left"><span style="font-family: 'Arial', 'sans-serif'; font-size: 9.00pt">The standard is effective for interim and annual reporting periods beginning after December 15, 2020.
