Newly Adopted Accounting Standards

(3) NEWLY ADOPTED ACCOUNTING STANDARDS

Liabilities (ASC 405)

In February 2013, the FASB issued new recognition and disclosure requirements for certain joint and several liability arrangements where the total amount of the obligation is fixed at the reporting date. For arrangements within the scope of this standard, PHI is required to measure such obligations as the sum of the amount it agreed to pay on the basis of its arrangement among co-obligors and any additional amount it expects to pay on behalf of its co-obligors. Adoption of this guidance during the first quarter of 2014 did not have a material impact on PHI’s consolidated financial statements.

Income Taxes (ASC 740)

In July 2013, the FASB issued new guidance requiring netting of certain unrecognized tax benefits against a deferred tax asset for a loss or other similar tax carryforward that would apply upon settlement of the uncertain tax position. The prospective adoption of this guidance at March 31, 2014 resulted in PHI netting liabilities related to uncertain tax positions with deferred tax assets for net operating loss and other carryforwards (included in deferred income tax liabilities, net) and income taxes receivable (including income tax deposits) related to effectively settled uncertain tax positions.
