Recently Adopted

Multiemployer Plans - In September 2011, the FASB issued Multiemployer Plans (Subtopic 715-80) - Disclosures about an Employer's Participation in a Multiemployer Plan (ASU No. 2011-09), which updates the Codification to require certain disclosures about an entity's involvement with multiemployer pension and other postretirement benefit plans. These updates do not affect recognition and measurement guidance for an employer's participation in multiemployer plans, but rather require additional disclosure such as the nature of multiemployer plans and the employer's participation, contributions to the plans and details regarding any significant plans. These updates to the Codification are effective for annual periods ending after Dec. 15, 2011. NSP-Wisconsin implemented the annual disclosure guidance effective Jan. 1, 2011, and the implementation did not have a material impact on its consolidated financial statements. For further information and required disclosures, see Note 6.

Recently Issued

Fair Value Measurement - In May 2011, the FASB issued Fair Value Measurement (Topic 820) - Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS (ASU No. 2011-04), which provides additional guidance for fair value measurements. These updates to the Codification include clarifications regarding existing fair value measurement principles and disclosure requirements, and also specific new guidance for items such as measurement of instruments classified within stockholders' equity. These updates to the Codification are effective for interim and annual periods beginning after Dec. 15, 2011.

These updates do not affect the items reported in OCI or the guidance for reclassifying such items to net income. These updates to the Codification are effective for interim and annual periods beginning after Dec. 15, 2011. NSP-Wisconsin does not expect the implementation of this presentation guidance to have a material impact on its consolidated financial statements.

Balance Sheet Offsetting - In December 2011, the FASB issued Balance Sheet (Topic 210) - Disclosures about Offsetting Assets and Liabilities (ASU No. 2011-11), which updates the Codification to require disclosures regarding netting arrangements in agreements underlying derivatives, certain financial instruments and related collateral amounts, and the extent to which an entity's financial statement presentation policies related to netting arrangements impact amounts recorded to the financial statements. These updates to the disclosure requirements of the Codification do not affect the presentation of amounts in the consolidated balance sheets, and are effective for annual reporting periods beginning on or after Jan. 1, 2013, and interim periods within those periods. NSP-Wisconsin does not expect the implementation of this disclosure guidance to have a material impact on its consolidated financial statements.
