Note 3: New Accounting Guidance

The Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC" or "Codification") is the sole source of authoritative GAAP other than the U.S. Securities and Exchange Commission ("SEC") issued rules and regulations that apply only to SEC registrants. The FASB issues an Accounting Standards Update ("ASU") to communicate changes to the Codification. We consider the applicability and impact of all ASUs.

We are currently evaluating the potential impact of adopting this new guidance on our Consolidated Financial Statements and related disclosures.
