Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The accompanying consolidated financial statements of the Company have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) and, in the opinion of management, includes all adjustments necessary for a fair presentation of the results of operations, comprehensive income (loss), financial position and cash flows for each period presented. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Principles of Consolidation The consolidated financial statements of the Company include the results of operations, financial position, and cash flows of Hawaiian Telcom Holdco, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Revenue Recognition Revenue is recognized when evidence of an arrangement exists, the earnings process is complete and collectibility is reasonably assured. The prices for certain services are filed in tariffs with the regulatory body that exercises jurisdiction over the services. Basic local service, enhanced calling features such as caller ID, special access circuits, long‑distance flat rate calling plans, most data services, internet, television, data center colocation and wireless services are billed one month in advance. Revenue for these services is recognized in the month services are rendered. The portion of advance‑billed services associated with services that will be delivered in a subsequent period is deferred and recorded as a liability in advance billings and customer deposits. Amounts billed to customers for activating wireline service are deferred and recognized over the average customer relationship. The costs associated with activating such services are deferred and recognized as an operating expense over the same period. Costs in excess of revenues are recognized as expense in the period in which activation occurs. Other charges for activation are generally deferred and recognized in revenue over the contract term. Revenues for providing usage based services, such as per‑minute long‑distance service, access charges billed to long‑distance companies for originating and terminating long‑distance calls on the Company’s network and video on demand, are billed in arrears. Revenues for these services are based on actual rated usage and, where necessary, historical usage patterns, and are recognized in the month services are rendered. For long-term indefeasible right of use, or IRU, contracts for fiber circuit capacity, the Company may receive up-front payments for services to be delivered for a period of up to 25 years. In these situations, the Company defers the revenue and amortizes it on a straight-line basis to earnings over the term of the contract. Universal Service revenue subsidies, including those related to Connect America Fund Phase II, are government‑sponsored support received in association with providing service in mostly rural, high‑cost areas. These revenues are typically calculated by the government agency responsible for administering the support program. These revenues are recognized as granted by the government agency. Telecommunication systems and structured cabling project revenues are recognized on a percentage completion basis, generally based on the relative portion of costs incurred to total estimated costs of a project, except for short duration projects which are recognized upon completion of the project. Maintenance services are recorded when the service is provided. With respect to arrangements with multiple deliverables, the Company determines whether more than one unit of accounting exists in an arrangement. To the extent that the deliverables are separable into multiple units of accounting, total consideration is allocated to the individual units of accounting based on their relative fair value, determined by the price of each deliverable when it is regularly sold on a stand‑alone basis. Revenue is recognized for each unit of accounting as delivered or as service is performed depending on the nature of the deliverable comprising the unit of accounting. Taxes Collected from Customers The Company presents taxes collected from customers and remitted to governmental authorities on a gross basis, including such amounts in the Company’s reported operating revenues and selling, general and administrative expenses. Such amounts represent primarily Hawaii state general excise taxes and HPUC fees. Such taxes and fees amounted to $8.4 million, $8.2 million and $7.5 million for the years ended December 31, 2016, 2015 and 2014, respectively. Cash and Cash Equivalents Cash and cash equivalents include cash and money market accounts with maturities at acquisition of three months or less. The majority of cash balances at December 31, 2016 are held in one bank in demand deposit accounts. Supplemental Non‑Cash Investing and Financing Activities Accounts payable included $26.1 million, $20.6 million and $21.2 million at December 31, 2016, 2015 and 2014, respectively, for additions to property, plant and equipment. Receivables The Company recognizes accounts receivable net of an allowance for doubtful accounts. The Company makes estimates of the uncollectibility of its accounts receivable by specifically analyzing accounts receivable and historic bad debts, customer concentrations, customer creditworthiness, current economic trends and changes in its customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. After multiple attempts at collection of delinquent accounts, the balance due is deemed uncollectible and charged against the allowance. Material and Supplies Material and supplies which consist mainly of cable, supplies and replacement parts, are stated at the lower of cost, determined principally by the average cost method, or net realizable value. Property and Depreciation Property, plant and equipment are carried at cost. Depreciation has been calculated using the composite remaining life method and straight-line depreciation. The composite method depreciates the remaining net investment in telephone plant over remaining economic asset lives by asset category. This method requires periodic review and revision of depreciation rates. The average economic lives utilized for assets are as follows: building – 18 to 34 years; cable and wire – 11 to 37 years; switching and circuit equipment – 6 to 15 years; and other property – 4 to 17 years. Software The Company capitalizes the costs associated with externally acquired software for internal use. Project costs associated with internally developed software are segregated into three project stages: preliminary project stage, application development stage and post‑implementation stage. Costs associated with both the preliminary project stage and post‑implementation stage are expensed as incurred. Costs associated with the application development stage are capitalized. Software maintenance and training costs are expensed as incurred. Capitalized software is generally amortized on a straight‑line method basis over its useful life, not to exceed five years. Goodwill and Other Intangible Assets Goodwill and other indefinite‑lived intangible assets are not amortized. Such assets are reviewed annually, or more frequently under various conditions, for impairment. The goodwill impairment test involves a two‑step process. The first step, identifying a potential impairment, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step will need to be conducted. The second step, measuring the impairment loss, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. Any excess of the reporting unit goodwill carrying value over the respective implied fair value is recognized as an impairment loss. The Company performs its annual impairment test during the fourth quarter, primarily using a market valuation and discounted cash flows methodology. Intangible assets with definite lives, including the value assigned to the customer base, are being amortized over the remaining estimated lives. For customer relationship intangibles, amortization is calculated using a declining balance method in relation to estimated retention lives of acquired customers. Impairment of Long‑Lived Assets The Company assesses the recoverability of long‑lived assets, including property, plant and equipment and definite‑lived intangible assets, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In such cases, if the sum of the expected cash flows, undiscounted and without interest, resulting from use of the asset are less than the carrying amount, an impairment loss is recognized based on the difference between the carrying amount and the fair value of the assets. Debt Issuance Deferred financing costs and original issue discount are amortized over the term of the related debt issuance using the effective interest method and presented as a direct deduction of the carrying amount of the debt. Income Taxes Deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities at each balance sheet date using enacted tax rates expected to be in effect in the year the differences are expected to reverse. Valuation allowances are recognized to reduce deferred tax assets to the amount that will more likely than not be realized. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense in the accompanying consolidated statements of income. Employee Benefit Plans Pension and postretirement health and life insurance benefits earned during the year as well as interest on projected benefit obligations are accrued currently. Actuarial gains and losses are amortized over the average remaining expected life of participants deemed inactive. Maintenance and Repairs The cost of maintenance and repairs, including the cost of replacing minor items not constituting substantial betterments, is charged to expense as these costs are incurred. Advertising Advertising costs are expensed as incurred. Advertising expense amounted to $6.1 million, $5.9 million and $6.1 million for the years ended December 31, 2016, 2015 and 2014, respectively. Stock Based Compensation The Company measures and recognizes the compensation expense for all share-based awards made to employees and directors based on estimated fair values. The fair value of restricted stock units is generally based on the closing price of the Company’s common stock on the date of grant. The fair value of market-based stock awards is estimated using a statistical pricing model as of the date of grant. Because stock-based compensation expense is based on awards ultimately expected to vest, it has been reduced for forfeitures. Earnings per Share Basic earnings per share is based on the weighted effect of all common shares issued and outstanding, and is calculated by dividing earnings by the weighted average shares outstanding during the period. Diluted earnings per share is calculated by dividing earnings, adjusted for the effect, if any, from assumed conversion of all potentially dilutive common shares outstanding, by the weighted average number of common shares used in the basic earnings per share calculation plus the number of common shares that would be issued assuming conversion of all potentially dilutive common shares outstanding. The denominator used to compute basic and diluted earnings per share is as follows: For the Year Ended December 31, 2016 2015 2014 Basic earnings per share - weighted average shares Effect of dilutive securities: Employee and director restricted stock units Warrants — Diluted earnings per share - weighted average shares For the years ended December 31, 2016, 2015 and 2014, all antidilutive restricted stock units excluded from the computation of weighted average dilutive shares outstanding were not significant. Recently Adopted Accounting Pronouncements In November 2016, the Financial Accounting Standards Board (“FASB”) issued an accounting standard modifying the presentation of restricted cash in the statement of cash flows. The new standard requires restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The Company adopted the standard effective upon issuance. The consolidated statement of cash flows for the year ended December 31, 2016 reflects application of the new standard. Retrospective application is required so the consolidated statement of cash flows for the years ended December 31, 2015 and December 31, 2014 were revised to reflect application of the new standard. This resulted in the following increases (decreases) to the total amounts previously reported in the consolidated statements of cash flows (dollars in thousands): For the Year Ended December 31, 2015 2014 Cash flows from operating activities: Changes in operating assets and liabilities: Prepaid expenses and other current assets $ — $ Advance billings and customer deposits — Other Net cash provided by operating activities Cash flows from investing activities: Funds released from restricted cash account — Proceeds on sale of investments — Net cash used in investing activities Net change in cash, cash equivalents and restricted cash Cash, cash equivalents and restricted cash, beginning of period — Cash, cash equivalents and restricted cash, end of period $ $ The following is a reconciliation of cash, cash equivalents and restricted cash reported in the consolidated balance sheets to the total of such amounts in the consolidated statements of cash flows (dollars in thousands): December 31, 2016 2015 Cash and cash equivalents $ $ Restricted cash included in other current assets Escrow deposits for capacity sales — Restricted cash included in other assets Escrow deposits for capacity sales — Other Total cash, cash equivalents and restricted cash $ $ The escrow deposits for capacity sales are more fully described in Note 13. The restriction on the escrow deposit is expected to be removed in 2017 so the restricted cash amount is reflected in other current assets as of December 31, 2016. Recently Issued Accounting Pronouncements In May 2014, the FASB issued a new accounting standard which provides guidance for revenue recognition which was most recently amended in May 2016. The new accounting standard will supersede the current revenue recognition requirements and most industry-specific guidance. The standard’s core principle is that a company will recognize revenue when it transfers 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. The new standard, along with the amendments which must be adopted at the same time as the new standard, is effective for the Company in the first quarter of 2018 with either full retrospective or modified retrospective adoption permitted. The modified retrospective approach requires a cumulative effect adjustment to retained earnings as of the beginning of the first reporting period for which the new accounting guidance is effective. Early adoption is allowed from the first quarter of 2017. The Company is currently evaluating the impact of the adoption of this accounting standard on the Company’s consolidated financial statements and financial statement disclosures. As this process is still ongoing, the final effect of adoption is not yet fully known. The Company has concluded that it will adopt the new standard in the first quarter of 2018. In conjunction with its efforts to prepare for adoption, the Company is focusing its analysis on timing of revenue recognition including for sales of certain telecommunications equipment. In addition, the Company is evaluating the need to modify its presentation of certain revenue related assets and liabilities in its consolidated balance sheet upon adoption of the new standard. In August 2014, the FASB issued an accounting standard with new guidance on management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related disclosures. Management must evaluate whether it is probable that known conditions or events, considered in the aggregate, would raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. If such conditions or events are identified, the standard requires management’s mitigation plans to alleviate the doubt or a statement of the substantial doubt about the entity’s ability to continue as a going concern to be disclosed in the financial statements. The standard is effective for fiscal years and interim periods beginning after December 15, 2016 applied on a prospective basis with early adoption permitted. The Company is not expecting a significant impact from adoption of this accounting standard. In February 2016, the FASB issued a new standard which revises the accounting for leases. The new standard is effective for the Company in the first quarter of 2019. The standard requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset and for operating leases the lessee would recognize lease expense on a straight-line basis. The standard requires use of a modified retrospective transition approach beginning with the earliest period presented in the period of transition. The Company is currently assessing the impact that adoption of this guidance will have on its consolidated financial statements. In March 2016, the FASB issued a new standard that simplifies the accounting for employee share-based payment transactions. The new standard impacts the accounting for related income taxes, forfeitures and statutory tax withholding requirements as well as the classification of certain related payments in the statement of cash flows. The new accounting guidance is effective for the Company in the first quarter of 2017 with early adoption permitted. The adoption method required is specified as retrospective, modified retrospective or prospective for each of the various accounting provisions impacted by this new standard. The Company will account for forfeitures on its share-based transactions as they occur beginning January 1, 2017. The impact of the modified retrospective adoption of this provision is not expected to be significant. In addition, the Company will begin accounting for excess tax benefits and tax deficiencies on share-based awards as income tax expense or benefit in its consolidated statement of income beginning January 1, 2017. In June 2016, the FASB issued amended guidance on accounting for the impairment of financial instruments. The standard requires adoption of an impairment model known as the current expected credit loss model that is based on expected losses rather than incurred losses. For the Company, it is anticipated this will impact primarily the accounting for credit losses on trade receivables. The new standard is effective for the Company in the first quarter of 2020 with early adoption permitted from the first quarter of 2019. The provisions of the new standard expected to impact the Company must be adopted using the modified retrospective approach. The Company is evaluating the effect of the guidance on the Company’s consolidated financial statements and financial statement disclosures. In January 2017, the FASB revised the accounting for goodwill impairments by eliminating the second step from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds the fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. The modified standard is effective for annual and any interim impairment tests for periods beginning after December 15, 2019. Early adoption is allowed for annual and any interim impairment tests occurring after January 1, 2017. The Company is not expecting a significant impact from adoption of this modified accounting standard.

The Company has selected the Eurocurrency rate as of December 31, 2016 resulting in an interest rate currently at 5.25%. The interest rate margin is subject to a further increase of 0.25% should there be a downgrade in the Company’s credit rating. The term loan provides for interest payments no less than quarterly. In addition, quarterly principal payments of $0.8 million are required. The balance of the loan is due at maturity on June 6, 2019. The Company must prepay, generally within three months after year end, up to 75% of excess cash flow, as defined. The percent of excess cash flow required is dependent on the Company’s leverage ratio. Excess cash flow payments due for the years ended December 31, 2016, 2015 and 2014 were not significant. The Company must also make prepayments on loans in the case of certain events such as large asset sales. In May 2016, the Company amended the term loan allowing for a revised leverage ratio financial covenant. The amendment modifies the maximum allowed leverage ratio, as defined, for the four consecutive fiscal quarters ended from June 30, 2016 to September 30, 2017 to 3.00:1.00, from December 31, 2017 to September 30, 2018 to 2.75:1.00, and from December 31, 2018 and each subsequent quarter to 2.50:1.00. In conjunction with the amendment, the Company paid a fee to the lenders of $0.4 million and such fee was deferred as financing related costs. The Company concluded that the amended lenders’ term loans were not substantially different than the lenders’ term loans prior to amendment. In addition, the Company paid an arrangement fee and legal costs amounting to $0.3 million. Such fees were expensed as incurred in 2016. The Company has a revolving credit facility which was extended on April 9, 2015 to mature on December 6, 2018. The facility has an available balance of $30.0 million with no amounts drawn at any time through December 31, 2016. A commitment fee is payable quarterly to the lender under the facility. Interest on amounts outstanding is based on, at the Company’s option, the bank prime rate plus a margin of 3.0% to 6.0% or the Eurocurrency rate for one, two, three or six month periods plus a margin of 4.0% to 5.5%. The margin is dependent on the Company’s leverage, as defined in the agreement, at the time of the borrowing. The obligations under the bank facilities are guaranteed by the Company and each subsidiary with certain exceptions. In addition, the bank credit facilities are collateralized by substantially all of the Company’s assets. The bank credit facilities contain various negative and affirmative covenants that restrict, among other things, incurrence of additional indebtedness, payment of dividends, redemptions of stock, other distributions to shareholders and sales of assets. In addition, there are financial covenants consisting of an interest coverage ratio, leverage ratio and a maximum level of capital expenditures. New Financing in 2017 In February 2017, the Company entered into a delayed draw credit agreement for new term loans and a new revolving credit facility. The new facility provides a commitment to fund repayment of the existing term loan and replacement of the existing revolving credit in May 2017. Included in the new facility is a term loan for $90.0 million with quarterly principal payments of $1.1 million with the balance due at maturity in May 2022. Interest, payable at least quarterly, is at the Alternate Base Rate plus a margin of 2.75% or a Eurocurrency rate plus a margin of 3.75%. In addition, the facility provides for a second term loan for $230.0 million with quarterly principal payments of $1.4 million for the first eight quarters and $2.9 million per quarter thereafter with the balance due at maturity in May 2023. Interest, payable at least quarterly, is at the Alternate Base Rate plus a margin of 3.00% or a Eurocurrency rate plus a margin of 4.00%. In addition, the agreement provides for a line of credit in the amount of $30.0 million with maturity in May 2022. Interest on the line of credit is at the Alternate Base Rate plus a margin of 2.75% or a Eurocurrency rate plus a margin of 3.75%. The interest rate margins on the facility are subject to a decrease of 0.25% with a defined improvement in the Company’s leverage ratio. Capitalized Interest Interest capitalized by the Company amounted to $1.6 million, $1.1 million and $1.1 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Employee Benefit Plans	8. Employee Benefit Plans Pension and Other Postretirement Benefits The Company sponsors a defined benefit pension plan, with benefits frozen as of March 1, 2012, and postretirement health and life insurance benefits for union employees. The Company also sponsors a cash balance pension plan for nonunion employees, with benefits frozen as of April 1, 2007, and certain management employees receive postretirement health and life insurance under grandfathered provisions of a terminated plan. In January 2017, the Company amended the postretirement health benefits plan for certain management employees by implementing a cap on the amount of the premium subsidy at 2017 levels. This curtailment of benefits will be recognized for financial reporting purposes in 2017. The change in projected benefit obligation, change in plan assets, funded status and weighted average actuarial assumptions were as follows (dollars in thousands): Pension Benefits Other Postretirement Benefits December 31, December 31, 2016 2015 2016 2015 Change in projected benefit obligation: Obligation at beginning of period $ $ $ $ Service cost — — Interest cost Actuarial (gain) loss Benefits paid Obligation at end of period Change in plan assets: Fair value of plan assets at beginning of period — — Actual return on plan assets — — Employer contributions Benefits paid Fair value of plan assets at end of period — — Funded status: Plan assets less than projected benefit obligation $ $ $ $ Amounts recognized on balance sheet: Other current liabilities $ — $ — $ $ Employee benefit obligation, noncurrent Net amount recognized $ $ $ $ Actuarial loss recognized in accumulated other comprehensive income (loss) $ $ $ $ Actuarial assumptions: Measurement date 12/31/2016 12/31/2015 12/31/2016 12/31/2015 Discount rate ranges from a low of % % % % Discount rate ranges to a high of % % % % Assumed health care cost trend rate, current NA NA % % Assumed health care cost trend rate, ultimate NA NA % % Assumed health care cost trend rate, ultimate year NA NA During the year ended December 31, 2016, the Company’s union pension plan paid lump-sum benefits to plan participants in full settlement of obligations due amounting to $7.1 million. This resulted in the recognition of a loss amounting to $1.3 million for the year ended December 31, 2016. During the year ended December 31, 2015, the Company’s pension plans paid lump-sum benefits to plan participants in full settlement of obligations due amounting to $55.9 million. This resulted in the recognition of a loss amounting to $8.1 million for the year ended December 31, 2015. The estimated amount of the actuarial loss to be amortized from accumulated other comprehensive income (loss) during 2017 is $0.5 million for pension benefits and $1.5 million for other postretirement benefits. The Company accrues the service costs of pension and postretirement benefits over the period from the date of hire until the date the employee becomes fully eligible for benefits. The following provides the components of benefit costs and weighted average actuarial assumptions for the years ended December 31, 2016, 2015 and 2014 (dollars in thousands): Pension Benefits For the For the Year Ended December 31, 2016 2015 2014 Interest cost $ $ $ Expected asset return Amortization of loss Net periodic benefit income Settlement loss — Total benefit (income) expense $ $ $ Actuarial assumptions: Discount rate ranges from a low of % % % Discount rate ranges to a high of % % % Expected return on plan assets % % % Other Postretirement Benefits For the For the Year Ended December 31, 2016 2015 2014 Service cost $ $ $ Interest cost Amortization of loss Total benefit expense $ $ $ Actuarial assumptions: Discount rate range from a low of % % % Discount rate range to a high of % % % Assumed health care cost trend rate, current % % % Assumed health care cost trend rate, ultimate % % % Assumed health care cost trend rate, ultimate year The measurement date for all plans was December 31, 2016, 2015 and 2014. At December 31, 2016 and 2015, the accumulated benefit obligation was the same as the projected benefit obligation. The Company based its selection of an assumed discount rate for 2017 net periodic benefit cost and December 31, 2016 disclosure on a cash flow matching analysis that utilized bond information provided from a bond index for all non-callable, high quality bonds (i.e., rated AA- or better) as of December 31, 2016. The matching of bond income to anticipated benefit cash flows and the basic methods of selecting the assumed discount rate and expected return on plan assets at December 31, 2016 did not change from December 31, 2015. In selecting the expected rate of return on plan assets of 7.00% for 2017 net periodic benefit cost, the Company considered economic forecasts for the types of investments held by the plans (primarily equity and fixed income investments), the plans’ asset allocations and the past performance of the plans’ assets. The expected rate of return on plan assets was based on various factors including historical experience and long-term inflation assumptions. The Company’s expected long-term rate of return on plan assets is determined using the target allocation of assets which is based on the goal of earning the highest rate of return while maintaining risk at acceptable levels. The plan strives to have assets sufficiently diversified so that adverse or unexpected results from a security class will not have a significant adverse impact on the entire portfolio. The Company’s overall investment strategy is to primarily invest for long‑term growth with sufficient investments available to fund near‑term benefit payments. The Company aims for diversification of asset types, fund strategies and fund managers. The target allocations for plan assets are 65 percent equity securities and 35 percent fixed income securities. Equity securities primarily include investments in equity funds and common stock of individual companies. Together these investments are diversified in both large and small cap companies located in the United States and internationally. Fixed income securities are in funds that invest in bonds of companies from diversified industries, mortgage‑backed securities and U.S. Treasuries. Accounting standards establish a fair value hierarchy when measuring the fair value of pension plan assets. The three levels of inputs within the hierarchy are defined as follows. Level 1 is quoted prices for identical assets or liabilities in active markets. Level 2 is significant other observable inputs other than level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 is significant unobservable inputs that reflect the Company’s own assumptions as to how market participants would price an asset. The fair values of the Company’s pension plan assets at December 31, 2016 and 2015, based on trading values or fund net asset value, by asset category and basis of valuation, are as follows (dollars in thousands): Quoted Prices in Active Significant Markets for Other Significant Identical Observable Unobservable Assets Inputs Inputs (Level 1) (Level 2) (Level 3) Total 2016 Common stocks - domestic large cap $ $ — $ — $ Equity funds - large cap index — — Fixed income funds - diversified bond — — Short term investment funds — — $ $ $ — $ 2015 Common stocks - domestic large cap $ $ — $ — $ Equity funds - large cap index — — Fixed income funds - diversified bond — — Short term investment funds — — $ $ $ — $ The fair values of the financial instruments shown in the table above represent the Company’s best estimates of the amounts that would be received upon sale of those assets in an orderly transaction between market participants at that date. Those fair value measurements maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset at the measurement date, the fair value measurement reflects the Company’s judgments about the assumptions that market participants would use in pricing the asset. Those judgments are developed by the Company based on the best information available in the circumstances. The Company used the following valuation methodologies for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2016 and 2015. Common stocks (Level 1) were valued at the closing price reported on the active market on which the individual securities are traded. Fixed income funds, equity funds, and short term investment funds (Level 2) were valued as follows. Fixed income funds are valued based on yields currently available on comparable securities of issuers with similar credit ratings. Equity funds and short term investment funds include commingled equity funds that are not open to public investment and are valued at the net asset value per share. All contributions made were as required by law. The Company expects to contribute $4.8 million to its defined benefit pension plans in 2017. The Company expects to contribute $3.3 million to its other postretirement benefit plans in 2017. The Company projects that its plans will make the following benefit payments for the years ended December 31 (dollars in thousands): Other Pension Plans Postretirement Benefits Paid Benefits Paid 2017 $ $ 2018 2019 2020 2021 2022 through 2026 $ $ Assumed health care costs trend rates have a significant impact on the amounts reported for other postretirement benefits. A one‑percentage point change in the assumed health care cost trend rates would have the following annual effects (dollars in thousands): 1-Percentage 1-Percentage Point Increase Point Decrease Effect on total of service and interest costs components $ $ Effect on postretirement benefit obligation 401(k) Plan The Company participates in two 401(k) employee savings plans that allow for voluntary contributions into designated investment funds by eligible employees with the Company matching employee contributions, up to a maximum of 10% of compensation for union employees and 6% of compensation for non-union employees. Company contributions were $5.1 million, $5.0 million and $5.1 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Availability of net operating losses in future periods may be subject to additional limitations if there is a deemed change in control for income tax reporting purposes. Such change in control will be determined for income tax reporting purposes based on future changes in stock ownership. In addition to the net operating losses disclosed previously, there was $1.4 million and $1.4 million of excess tax deductions available at December 31, 2016 and 2015, respectively, related to employee stock expense for which a benefit will be recorded to additional paid-in capital when realized. The valuation allowance is related to charitable loss carry forwards subject to deduction limitations. If there is a decline in the level of actual future or forecasted earnings, the conclusion regarding the need for a valuation allowance may change in future periods resulting in the establishment of a valuation allowance for some or all of the deferred income tax assets.

The warrants to purchase shares could be exercised from January 26, 2011 to the maturity on October 28, 2015. The warrants could be exercised on a cashless basis whereby a portion of the exercised warrants are tendered in lieu of payment for the exercise price. During the years ended December 31, 2015 and 2014, warrants were exercised on a cashless basis resulting in the issuance of 228,316 and 73,422 shares of common stock, respectively. In addition, during the year ended December 31, 2015, another 490,759 warrants were exercised for cash consideration of $6.9 million. Equity Incentive Plan The Compensation Committee of the Company’s Board of Directors may grant awards under the Company’s equity incentive plan in the form of incentive stock options, non‑qualified stock options, stock appreciation rights, restricted stock, restricted stock units and other stock‑based awards. The maximum number of shares issuable under the equity incentive plan is 1,400,000 shares with 638,000 shares remaining to be issued at December 31, 2016. All grants under the equity incentive plan will be issued at the fair value of the Company’s common stock on date of grant. As of December 31, 2016, all awards were restricted stock units. Restricted Stock Units Restricted stock units are generally subject to forfeiture if employment terminates prior to release of the restrictions. The Company expenses the cost of restricted stock units, which is determined to be the fair market value of the shares at the date of grant, ratably over the period during which the restrictions lapse. Restricted stock units have service, performance and market conditions for vesting. Those with service conditions vest in equal installments on each of the first through fourth anniversaries of the date of grant except for those granted to directors which vest over one year. Those with performance and market conditions vest in installments over four years based on the achievement of goals established by the Compensation Committee of the Company’s Board of Directors. Activity with respect to outstanding restricted stock units for the years ended December 31, 2016, 2015 and 2014 was as follows: Weighted- Average Grant-Date Fair Shares Value per Share Nonvested at January 1, 2014 $ Granted Vested Forfeited Nonvested at December 31, 2014 Granted Vested Forfeited Nonvested at December 31, 2015 Granted Vested Forfeited Nonvested at December 31, 2016 $ As of December 31, 2016, there was $3.7 million of unrecognized share-based compensation expense related to nonvested restricted stock unit awards expected to vest. The cost is expected to be recognized over a weighted-average period of two years. The Company recognized compensation expense of $2.3 million, $1.6 million and $4.2 million for the years ended December 31, 2016, 2015 and 2014, respectively. For the year ended December 31, 2016, the Company had granted restricted stock units with market conditions. The Company valued those units for expense recognition purposes using a Monte Carlo simulation model with an expected volatility for the Company’s shares of 24.1%, a risk free return of 0.85% and no expected dividends. The fair value as of the vesting date for the restricted stock units that vested during the years ended December 31, 2016, 2015 and 2014 was $1.0 million, $2.6 million and $3.9 million, respectively. Upon vesting, unit holders have the option to net share-settle to cover the required withholding tax and the remaining amount is converted into an equivalent number of shares of common stock. The total shares withheld were 15,772, 36,592 and 53,775 for the years ended December 31, 2016, 2015 and 2014, respectively, and were based on the value of the restricted stock units as determined by the Company’s closing stock price on the date of vesting. Total payments for the employees’ tax obligations to the tax authorities was $0.4 million, $0.9 million and $1.5 million for the years ended December 31, 2016, 2015 and 2014, respectively. Other than reimbursements for tax withholdings, there was no cash received under the restricted stock unit arrangements. In 2014, the terms of certain restricted stock units were modified which resulted in the restricted stock units vesting as of the date of the modification. The Company recognized the incremental value of $0.6 million as additional expense in 2014. Performance Based Stock Compensation The Company has a performance based compensation plan. The incentive compensation is settled in March of each year for the prior year services and is based on Company performance relative to certain company specific metrics. The Company recognizes the expense during the performance period based on the expected compensation amount. The compensation for the performance period ended December 31, 2015 was settled in cash in March 2016. Beginning for the 2016 performance period, a specified portion of the compensation amount for certain employees will be settled in Company shares based on the share price at the date of settlement. Upon settlement, employees will net share-settle to cover the required withholding tax and the remaining amount is converted into an equivalent number of shares of common stock. The performance based compensation to be settled in stock amounted to $0.6 million for the year ended December 31, 2016.

The total system cost is $235 million and is primarily composed of a supply contract with the lead contractor. The Company will invest $25 million over the multi-year construction period for a fractional ownership in the system. The fixed fee component of the investment is included in the above fixed fee commitments. The Company will recognize its fractional share of the cost. In addition, the Company will construct a cable landing station in Hawaii and provide cable landing services. The system is expected to be completed in the second half of 2017. As of December 31, 2016, the Company had incurred costs of $16.6 million primarily to the cable contractor for construction with all such costs capitalized to telephone plant under construction. The Company will have excess capacity on its share of the trans-Pacific cable that it will make available to other carriers for a fee. The Company has contracted and expects to enter into additional contracts with other carriers for long-term indefeasible right of use, or IRU, agreements for fiber circuit capacity. The Company may receive up-front payments for services to be delivered over a period of up to 25 years. The Company has entered into agreements for the sale of capacity for $27.0 million plus fees to activate assigned capacity, and for operations and maintenance. As of December 31, 2016, the Company had received up-front payments of $7.2 million. As provided for in one of the agreements, funds of $5.0 million were held in escrow. The funds in escrow will be released to the Company when the trans-Pacific cable is ready for service. The restricted cash is reflected in other current assets in the consolidated balance sheet at December 31, 2016. A liability to provide services in the future for all up-front payments is included in advance billings and customer deposits and other liabilities. The Company will recognize revenue for the circuit, beginning upon activation of the services, on a straight-line basis over the contract term. Connect America Fund Phase II In conjunction with reforming the Universal Service Fund, the Federal Communications Commission (“FCC”) established the Connect America Fund (“CAF”) which provides incremental support to broadband service providers. CAF Phase II is the long-term component of the program. In August 2015, the Company notified the FCC that it is accepting CAF Phase II support which amounts to $4.4 million in annual funding. Support is retroactive through the beginning of 2015, net of certain other receipts from the Universal Service Fund, and will continue for six years. Under the terms of CAF Phase II, the Company will offer broadband service at 10 Mbps downstream and 1 Mbps upstream or better to approximately 11,000 eligible locations in high-cost areas in the State of Hawaii and will provide voice and broadband services at reasonable rates. For the years ended December 31, 2016 and 2015, the Company recognized $4.4 and $3.3 million, respectively, in CAF Phase II funding as revenue in the consolidated income statement. Other Installment Contracts The Company has various other fixed installment contacts generally in conjunction with acquisition of assets. These agreements generally have a component representing interest at fixed rates in addition to principal. As of December 31, 2016, the commitments were as follows (dollars in thousands): Years ended, December 31: 2017 $ 2018 2019 2020 2021 Thereafter Less amount representing interest Present value Current reflected in other current liabilities Noncurrent reflected in other liabilities $ Collective Bargaining Agreement The Company has a collective bargaining agreement with the International Brotherhood of Electrical Workers Local 1357 (“IBEW”) that expires on December 31, 2017. The agreement covers approximately half of the Company’s workforce. Joint-Owned Utility Poles Each of the electric utilities for the four counties in the State of Hawaii have separate agreements with the Company for the joint ownership and maintenance of utility poles along with other third parties, such as the State of Hawaii. The agreements set forth various circumstances requiring pole removal, installation and replacement and the sharing of costs among the joint pole owners. The agreements allow for the cost of work done by one joint pole owner to be shared by the other joint pole owners based on the apportionment of costs in the agreements. Generally, the electric utilities have maintained, replaced and installed the majority of the jointly-owned poles and have billed the other joint pole owners for their respective share of the costs. The Company has a disagreement with the common owner of the utilities in three of the counties regarding the amount the utilities are requesting for their share of the capitalized costs. For one of the three utilities referenced above, a dispute resolution process is proceeding as specified by the joint pole agreement. For another of the utilities, a complaint for payment was filed by the utility with the State court in 2016. Management of the Company believes the amount recognized in the Company’s consolidated financial statements for amounts due the utilities are reflective of what is owed and a reasonable estimate of the final settlement to be reached with the utilities. Litigation The Company is involved in litigation arising in the normal course of business. The outcome of litigation is not expected to have a material adverse impact on the Company’s consolidated financial statements.

Fair Value of Financial Instruments
Fair Value of Financial Instruments	14. Fair Value of Financial Instruments The following method and assumptions were used to estimate the fair value of each class of financial instruments for which it is practical to estimate the fair value. Cash and cash equivalents, accounts receivable and accounts payable – The carrying amount approximates fair value. The valuation is based on settlements of similar financial instruments all of which are short-term in nature and generally settled at or near cost. Cash and cash equivalents are measured at Level 1. Investment securities – The fair value of investment securities was based on quoted market prices. Investment securities were included in other assets on the consolidated balance sheets. Debt – The fair value of debt is based on the value at which debt is trading among holders. The estimated fair value of financial instruments is as follows (dollars in thousands): Carrying Fair Value Value December 31, 2016 Liabilities - long-term debt (carried at cost) December 31, 2015 Liabilities - long-term debt (carried at cost) Fair Value Measurements The objective of the fair value measurement is to estimate the price at which an orderly transaction to sell the asset or to transfer the liability would take place between market participants at the measurement date under current market conditions. Accounting standards establish a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). Liabilities carried at amortized cost with fair value disclosure on a recurring basis represent long-term debt. A summary is as follows (dollars in thousands): December 31, 2016 2015 Liability value measurements using: Quoted prices in active markets for identical liabilities (Level 1) $ — $ — Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) — — $ $

Summary of Significant Accoun26

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Summary of Significant Accounting Policies
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements of the Company include the results of operations, financial position, and cash flows of Hawaiian Telcom Holdco, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Revenue Recognition	Revenue Recognition Revenue is recognized when evidence of an arrangement exists, the earnings process is complete and collectibility is reasonably assured. The prices for certain services are filed in tariffs with the regulatory body that exercises jurisdiction over the services. Basic local service, enhanced calling features such as caller ID, special access circuits, long‑distance flat rate calling plans, most data services, internet, television, data center colocation and wireless services are billed one month in advance. Revenue for these services is recognized in the month services are rendered. The portion of advance‑billed services associated with services that will be delivered in a subsequent period is deferred and recorded as a liability in advance billings and customer deposits. Amounts billed to customers for activating wireline service are deferred and recognized over the average customer relationship. The costs associated with activating such services are deferred and recognized as an operating expense over the same period. Costs in excess of revenues are recognized as expense in the period in which activation occurs. Other charges for activation are generally deferred and recognized in revenue over the contract term. Revenues for providing usage based services, such as per‑minute long‑distance service, access charges billed to long‑distance companies for originating and terminating long‑distance calls on the Company’s network and video on demand, are billed in arrears. Revenues for these services are based on actual rated usage and, where necessary, historical usage patterns, and are recognized in the month services are rendered. For long-term indefeasible right of use, or IRU, contracts for fiber circuit capacity, the Company may receive up-front payments for services to be delivered for a period of up to 25 years. In these situations, the Company defers the revenue and amortizes it on a straight-line basis to earnings over the term of the contract. Universal Service revenue subsidies, including those related to Connect America Fund Phase II, are government‑sponsored support received in association with providing service in mostly rural, high‑cost areas. These revenues are typically calculated by the government agency responsible for administering the support program. These revenues are recognized as granted by the government agency. Telecommunication systems and structured cabling project revenues are recognized on a percentage completion basis, generally based on the relative portion of costs incurred to total estimated costs of a project, except for short duration projects which are recognized upon completion of the project. Maintenance services are recorded when the service is provided. With respect to arrangements with multiple deliverables, the Company determines whether more than one unit of accounting exists in an arrangement. To the extent that the deliverables are separable into multiple units of accounting, total consideration is allocated to the individual units of accounting based on their relative fair value, determined by the price of each deliverable when it is regularly sold on a stand‑alone basis. Revenue is recognized for each unit of accounting as delivered or as service is performed depending on the nature of the deliverable comprising the unit of accounting.
Taxes Collected from Customers	Taxes Collected from Customers The Company presents taxes collected from customers and remitted to governmental authorities on a gross basis, including such amounts in the Company’s reported operating revenues and selling, general and administrative expenses. Such amounts represent primarily Hawaii state general excise taxes and HPUC fees. Such taxes and fees amounted to $8.4 million, $8.2 million and $7.5 million for the years ended December 31, 2016, 2015 and 2014, respectively.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash and money market accounts with maturities at acquisition of three months or less. The majority of cash balances at December 31, 2016 are held in one bank in demand deposit accounts.
Supplemental Non-Cash Investing and Financing Activities	Supplemental Non‑Cash Investing and Financing Activities Accounts payable included $26.1 million, $20.6 million and $21.2 million at December 31, 2016, 2015 and 2014, respectively, for additions to property, plant and equipment.
Receivables	Receivables The Company recognizes accounts receivable net of an allowance for doubtful accounts. The Company makes estimates of the uncollectibility of its accounts receivable by specifically analyzing accounts receivable and historic bad debts, customer concentrations, customer creditworthiness, current economic trends and changes in its customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. After multiple attempts at collection of delinquent accounts, the balance due is deemed uncollectible and charged against the allowance.
Material and Supplies	Material and Supplies Material and supplies which consist mainly of cable, supplies and replacement parts, are stated at the lower of cost, determined principally by the average cost method, or net realizable value.
Property and Depreciation	Property and Depreciation Property, plant and equipment are carried at cost. Depreciation has been calculated using the composite remaining life method and straight-line depreciation. The composite method depreciates the remaining net investment in telephone plant over remaining economic asset lives by asset category. This method requires periodic review and revision of depreciation rates. The average economic lives utilized for assets are as follows: building – 18 to 34 years; cable and wire – 11 to 37 years; switching and circuit equipment – 6 to 15 years; and other property – 4 to 17 years.
Software	Software The Company capitalizes the costs associated with externally acquired software for internal use. Project costs associated with internally developed software are segregated into three project stages: preliminary project stage, application development stage and post‑implementation stage. Costs associated with both the preliminary project stage and post‑implementation stage are expensed as incurred. Costs associated with the application development stage are capitalized. Software maintenance and training costs are expensed as incurred. Capitalized software is generally amortized on a straight‑line method basis over its useful life, not to exceed five years.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill and other indefinite‑lived intangible assets are not amortized. Such assets are reviewed annually, or more frequently under various conditions, for impairment. The goodwill impairment test involves a two‑step process. The first step, identifying a potential impairment, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the second step will need to be conducted. The second step, measuring the impairment loss, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. Any excess of the reporting unit goodwill carrying value over the respective implied fair value is recognized as an impairment loss. The Company performs its annual impairment test during the fourth quarter, primarily using a market valuation and discounted cash flows methodology. Intangible assets with definite lives, including the value assigned to the customer base, are being amortized over the remaining estimated lives. For customer relationship intangibles, amortization is calculated using a declining balance method in relation to estimated retention lives of acquired customers.
Impairment of Long-Lived Assets	Impairment of Long‑Lived Assets The Company assesses the recoverability of long‑lived assets, including property, plant and equipment and definite‑lived intangible assets, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In such cases, if the sum of the expected cash flows, undiscounted and without interest, resulting from use of the asset are less than the carrying amount, an impairment loss is recognized based on the difference between the carrying amount and the fair value of the assets.
Debt Issuance	Debt Issuance Deferred financing costs and original issue discount are amortized over the term of the related debt issuance using the effective interest method and presented as a direct deduction of the carrying amount of the debt.
Income Taxes	Income Taxes Deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities at each balance sheet date using enacted tax rates expected to be in effect in the year the differences are expected to reverse. Valuation allowances are recognized to reduce deferred tax assets to the amount that will more likely than not be realized. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense in the accompanying consolidated statements of income.
Employee Benefit Plans	Employee Benefit Plans Pension and postretirement health and life insurance benefits earned during the year as well as interest on projected benefit obligations are accrued currently. Actuarial gains and losses are amortized over the average remaining expected life of participants deemed inactive.
Maintenance and Repairs	Maintenance and Repairs The cost of maintenance and repairs, including the cost of replacing minor items not constituting substantial betterments, is charged to expense as these costs are incurred.
Advertising	Advertising Advertising costs are expensed as incurred. Advertising expense amounted to $6.1 million, $5.9 million and $6.1 million for the years ended December 31, 2016, 2015 and 2014, respectively.
Stock Based Compensation	Stock Based Compensation The Company measures and recognizes the compensation expense for all share-based awards made to employees and directors based on estimated fair values. The fair value of restricted stock units is generally based on the closing price of the Company’s common stock on the date of grant. The fair value of market-based stock awards is estimated using a statistical pricing model as of the date of grant. Because stock-based compensation expense is based on awards ultimately expected to vest, it has been reduced for forfeitures.
Earnings per Share	Earnings per Share Basic earnings per share is based on the weighted effect of all common shares issued and outstanding, and is calculated by dividing earnings by the weighted average shares outstanding during the period. Diluted earnings per share is calculated by dividing earnings, adjusted for the effect, if any, from assumed conversion of all potentially dilutive common shares outstanding, by the weighted average number of common shares used in the basic earnings per share calculation plus the number of common shares that would be issued assuming conversion of all potentially dilutive common shares outstanding. The denominator used to compute basic and diluted earnings per share is as follows: For the Year Ended December 31, 2016 2015 2014 Basic earnings per share - weighted average shares Effect of dilutive securities: Employee and director restricted stock units Warrants — Diluted earnings per share - weighted average shares For the years ended December 31, 2016, 2015 and 2014, all antidilutive restricted stock units excluded from the computation of weighted average dilutive shares outstanding were not significant.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In November 2016, the Financial Accounting Standards Board (“FASB”) issued an accounting standard modifying the presentation of restricted cash in the statement of cash flows. The new standard requires restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The Company adopted the standard effective upon issuance. The consolidated statement of cash flows for the year ended December 31, 2016 reflects application of the new standard. Retrospective application is required so the consolidated statement of cash flows for the years ended December 31, 2015 and December 31, 2014 were revised to reflect application of the new standard. This resulted in the following increases (decreases) to the total amounts previously reported in the consolidated statements of cash flows (dollars in thousands): For the Year Ended December 31, 2015 2014 Cash flows from operating activities: Changes in operating assets and liabilities: Prepaid expenses and other current assets $ — $ Advance billings and customer deposits — Other Net cash provided by operating activities Cash flows from investing activities: Funds released from restricted cash account — Proceeds on sale of investments — Net cash used in investing activities Net change in cash, cash equivalents and restricted cash Cash, cash equivalents and restricted cash, beginning of period — Cash, cash equivalents and restricted cash, end of period $ $ The following is a reconciliation of cash, cash equivalents and restricted cash reported in the consolidated balance sheets to the total of such amounts in the consolidated statements of cash flows (dollars in thousands): December 31, 2016 2015 Cash and cash equivalents $ $ Restricted cash included in other current assets Escrow deposits for capacity sales — Restricted cash included in other assets Escrow deposits for capacity sales — Other Total cash, cash equivalents and restricted cash $ $ The escrow deposits for capacity sales are more fully described in Note 13. The restriction on the escrow deposit is expected to be removed in 2017 so the restricted cash amount is reflected in other current assets as of December 31, 2016. Recently Issued Accounting Pronouncements In May 2014, the FASB issued a new accounting standard which provides guidance for revenue recognition which was most recently amended in May 2016. The new accounting standard will supersede the current revenue recognition requirements and most industry-specific guidance. The standard’s core principle is that a company will recognize revenue when it transfers 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. The new standard, along with the amendments which must be adopted at the same time as the new standard, is effective for the Company in the first quarter of 2018 with either full retrospective or modified retrospective adoption permitted. The modified retrospective approach requires a cumulative effect adjustment to retained earnings as of the beginning of the first reporting period for which the new accounting guidance is effective. Early adoption is allowed from the first quarter of 2017. The Company is currently evaluating the impact of the adoption of this accounting standard on the Company’s consolidated financial statements and financial statement disclosures. As this process is still ongoing, the final effect of adoption is not yet fully known. The Company has concluded that it will adopt the new standard in the first quarter of 2018. In conjunction with its efforts to prepare for adoption, the Company is focusing its analysis on timing of revenue recognition including for sales of certain telecommunications equipment. In addition, the Company is evaluating the need to modify its presentation of certain revenue related assets and liabilities in its consolidated balance sheet upon adoption of the new standard. In August 2014, the FASB issued an accounting standard with new guidance on management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related disclosures. Management must evaluate whether it is probable that known conditions or events, considered in the aggregate, would raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. If such conditions or events are identified, the standard requires management’s mitigation plans to alleviate the doubt or a statement of the substantial doubt about the entity’s ability to continue as a going concern to be disclosed in the financial statements. The standard is effective for fiscal years and interim periods beginning after December 15, 2016 applied on a prospective basis with early adoption permitted. The Company is not expecting a significant impact from adoption of this accounting standard. In February 2016, the FASB issued a new standard which revises the accounting for leases. The new standard is effective for the Company in the first quarter of 2019. The standard requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset and for operating leases the lessee would recognize lease expense on a straight-line basis. The standard requires use of a modified retrospective transition approach beginning with the earliest period presented in the period of transition. The Company is currently assessing the impact that adoption of this guidance will have on its consolidated financial statements. In March 2016, the FASB issued a new standard that simplifies the accounting for employee share-based payment transactions. The new standard impacts the accounting for related income taxes, forfeitures and statutory tax withholding requirements as well as the classification of certain related payments in the statement of cash flows. The new accounting guidance is effective for the Company in the first quarter of 2017 with early adoption permitted. The adoption method required is specified as retrospective, modified retrospective or prospective for each of the various accounting provisions impacted by this new standard. The Company will account for forfeitures on its share-based transactions as they occur beginning January 1, 2017. The impact of the modified retrospective adoption of this provision is not expected to be significant. In addition, the Company will begin accounting for excess tax benefits and tax deficiencies on share-based awards as income tax expense or benefit in its consolidated statement of income beginning January 1, 2017. In June 2016, the FASB issued amended guidance on accounting for the impairment of financial instruments. The standard requires adoption of an impairment model known as the current expected credit loss model that is based on expected losses rather than incurred losses. For the Company, it is anticipated this will impact primarily the accounting for credit losses on trade receivables. The new standard is effective for the Company in the first quarter of 2020 with early adoption permitted from the first quarter of 2019. The provisions of the new standard expected to impact the Company must be adopted using the modified retrospective approach. The Company is evaluating the effect of the guidance on the Company’s consolidated financial statements and financial statement disclosures. In January 2017, the FASB revised the accounting for goodwill impairments by eliminating the second step from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds the fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. The modified standard is effective for annual and any interim impairment tests for periods beginning after December 15, 2019. Early adoption is allowed for annual and any interim impairment tests occurring after January 1, 2017. The Company is not expecting a significant impact from adoption of this modified accounting standard.
