New Accounting Pronouncements and Changes in Accounting Principles [Abstract] |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In July 2013, the FASB issued ASU 2013-10 which amends ASC 815 to include the Fed Funds Effective Swap Rate as an appropriate benchmark interest rate in the accounting for fair value and cash flow hedges in the United States, in addition to the interest rates on direct Treasury obligations of the U.S. government and LIBOR. Additionally, entities are no longer prohibited from using different benchmark interest rates for similar hedges except in rare and justifiable circumstances. The ASU applies prospectively to qualifying new hedging relationships entered into on or after July 17, 2013, or to hedging relationships redesignated on or after that date. NiSource is currently reviewing the provisions of the new standard to determine the impact on its Condensed Consolidated Financial Statements (unaudited) and Notes to Condensed Consolidated Financial Statements (unaudited). In July 2013, the FASB issued ASU 2013-11, which provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or tax credit carryforward exists. The ASU is effective for annual periods beginning after December 15, 2013, and interim periods within those annual periods. NiSource is currently reviewing the provisions of the new standard to determine the impact on its Condensed Consolidated Financial Statements (unaudited) and Notes to Condensed Consolidated Financial Statements (unaudited) but expects that the ASU will not have a material impact.
