Schedule of new accounting pronouncements and changes in accounting principles

As new accounting pronouncements are issued, we will adopt those that are applicable under the circumstances.

Recently Issued Accounting Standards Not Yet Adopted
Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
ASU 2021-08: Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers	This guidance amends ASC 805 to add contract assets and contract liabilities to the list of exceptions to the recognition and measurement principles that apply to business combinations and to require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination. Under current GAAP, an acquirer generally recognizes such items at fair value at acquisition date.	January 1, 2023	Upon adoption on the effective date, the amendments will be applied prospectively to business combinations. Early adoption is permitted in an interim period; however, retrospective application is required for any acquisitions occurring after the beginning of the fiscal year that includes the interim period of early application. We are currently assessing the adoption impact of this standard; however, we do not anticipate a material impact from applying the recognition and measurement principles of Topic 606 to contract assets or liabilities acquired as part of a business combination.
