The preparation of the consolidated financial statements in accordance with US GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Estimates and judgments are based on historical experience, current conditions and various other assumptions believed to be reasonable under the circumstances. Additionally, certain estimates and judgments are necessary since the regulatory environments in which the Corporation's utilities operate often require amounts to be recorded at estimated values until these amounts are finalized pursuant to regulatory decisions or other regulatory proceedings. In April 2013 Newfoundland Power received a decision related to the utility's cost of capital for 2013 through 2015, the cumulative impacts of which will be recorded in the second quarter of 2013, when the decision was received, with the impact related to the first quarter of 2013 determined to be immaterial. Due to changes in facts and circumstances and the inherent uncertainty involved in making estimates, actual results may differ significantly from current estimates. Estimates and judgments are reviewed periodically and, as adjustments become necessary, are reported in earnings in the period in which they become known.

Interim financial statements may also employ a greater use of estimates than the annual financial statements. There were no material changes in the nature of the Corporation's critical accounting estimates during the three months ended March 31, 2013.

An evaluation of subsequent events through to May 6, 2013, the date these interim consolidated financial statements were approved by the Audit Committee of the Board of Directors, was completed to determine whether circumstances warranted recognition and disclosure of events or transactions in the interim consolidated financial statements as at March 31, 2013.

All amounts are presented in Canadian dollars unless otherwise stated.

These interim consolidated financial statements include the accounts of Fortis and its wholly owned subsidiaries and controlling ownership interests. All significant intercompany balances and transactions have been eliminated on consolidation.

These interim consolidated financial statements have been prepared following the same accounting policies and methods as those used to prepare the Corporation's 2012 annual audited consolidated financial statements, except as described below.

NEW ACCOUNTING POLICIES

Disclosures About Offsetting Assets and Liabilities

Effective January 1, 2013, the Corporation adopted the amendments to Accounting Standards Codification ("ASC") Topic 210, Balance Sheet - Disclosures About Offsetting Assets and Liabilities as outlined in Accounting Standards Updates ("ASU") No. 2011-11 and 2013-01. The amendments improve the transparency of the effect or potential effect of netting arrangements on a company's financial position by expanding the level of disclosures required by entities for such arrangements. The amended disclosures are intended to assist financial statement users in understanding significant quantitative differences between balance sheets prepared under US GAAP and International Financial Reporting Standards ("IFRS"). ASU No. 2013-01 limits the scope of the new offsetting disclosure requirements previously issued in ASU No. 2011-11 to certain derivative instruments, repurchase and reverse repurchase agreements, and securities borrowing and lending arrangements that are either offset on the balance sheet or subject to an enforceable master netting or similar arrangement. The above-noted amendments were applied retrospectively and did not materially impact the Corporation's interim consolidated financial statements for the three months ended March 31, 2013.
