Recent Accounting Literature [Abstract]
Recent Accounting Literature	(2) Recent Accounting Literature: Revenue Recognition In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, “Revenue from Contracts with Customers.” This standard, along with its related amendments, requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. This new standard is effective for annual and interim reporting periods beginning after December 15, 2017. Companies are also permitted to voluntarily adopt the new standard as of the original effective date that was for annual reporting periods beginning after December 15, 2016. Companies are permitted to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. Frontier is currently evaluating the adoption of the new standard to determine the impact that it will have on Frontier’s processes, systems and internal controls, but has not yet selected a transition method or determined the impact of adoption on its consolidated financial statements. Employee Benefit Plans In July 2015, the FASB issued ASU No. 2015-12, “Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), and Health and Welfare Benefit Plans (Topic 965)”: There are three parts to the ASU that aim to simplify the accounting and presentation of plan accounting. Part I of this ASU requires fully benefit-responsive investment contracts to be measured at contract value instead of the current fair value measurement. Part II of this ASU requires investments (both participant-directed and nonparticipant-directed investments) of employee benefit plans be grouped only by general type, eliminating the need to disaggregate the investments in multiple ways. Part III of this ASU provides a similar measurement date practical expedient for employee benefit plans as available in ASU No. 2015-04, “Compensation – Retirement Benefits (Topic 715),” which allows employers to measure defined benefit plan assets on a month-end date that is nearest to the year’s fiscal year-end when the fiscal period does not coincide with a month-end. Parts I and II of the new guidance should be applied on a retrospective basis. Part III of the new guidance should be applied on a prospective basis. The adoption of ASU 2015-12 will impact certain of the disclosures related to our pension plan assets, but otherwise is not expected to have a material impact on our consolidated financial statements. Leases In February 2016, the FASB issued ASU No. 2016 – 02, “Leases (Topic 842).” This standard establishes the principles to report transparent and economically neutral information about the assets and liabilities that arise from leases. Upon implementation, lessees will need to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability. It will be critical to identify leases embedded in a contract to avoid misstating the lessee’s balance sheet. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting, but without explicit bright lines. Lessor accounting is similar to the current model, but updated to align with certain changes to the lessee model and the new revenue recognition standard. Existing sale-leaseback guidance, including guidance for real estate, is replaced with a new model applicable to both lessees and lessors. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. Frontier is currently evaluating the impact of adopting the new standard, but has not yet determined the impact of adoption on its consolidated financial statements. Compensation – Stock Compensation In March 2016 the FASB issued ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting,” to amend ASC Topic 718, “Compensation – Stock Compensation.” The ASU is part of the FASB’s ongoing simplification initiative, which is designed to reduce cost and complexity while maintaining or improving the usefulness of the information provided to the users of financial statements. The proposed simplifications address a variety of areas for public entities, including the following: 1) accounting for income taxes, 2) classification of excess tax benefits on the statement of cash flows, 3) forfeitures, 4) minimum statutory tax withholding requirements, 5) classifications of employee taxes paid on the statement of cash flows when an employer withholds shares for tax withholding purposes, and 6) classification of awards with repurchase features. The new guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Frontier is currently evaluating the impact of adopting the new standard, but has not yet determined the impact of adoption on its consolidated financial statements. Cash Flows – Classification of Certain Cash Receipts and Cash Payments In August 2016 the FASB issued ASU No. 2016-15,” Statement of Cash Flows – Classification of Certain Cash Receipts and Cash Payments.” This ASU addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments in this ASU provide guidance on the following cash flow issues: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments; 3) contingent consideration payments made after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; 6) distributions received from equity method investees; 7) beneficial interests in securitization transactions; and 8) separately identifiable cash flows and application of the predominance principle. The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early application is permitted. Frontier is currently evaluating the impact of adopting the new standard, but has not yet determined the impact of adoption on its consolidated financial statements.

Revenue Recognition

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, “Revenue from Contracts with Customers.” This standard, along with its related amendments, requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services.

Companies are permitted to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. Frontier is currently evaluating the adoption of the new standard to determine the impact that it will have on Frontier’s processes, systems and internal controls, but has not yet selected a transition method or determined the impact of adoption on its consolidated financial statements.
