Basis of Presentation
	2.  Basis of Presentation
	The accompanying unaudited condensed 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 rules and regulations of the U.S. Securities and Exchange Commission. Certain information and disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted and condensed. In the opinion of the Company’s management, all adjustments (consisting of only normal and recurring accruals) have been made to present fairly the results of operations, comprehensive income, financial position and cash flows for the periods presented. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full year. Although the Company believes that the disclosures are adequate to make the information presented not misleading, these financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of and for the year ended December 31, 2014.
	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 March 31, 2015 are held in one bank in demand deposit accounts.
	Supplemental Non-Cash Investing and Financing Activities
	Accounts payable included $15.2 million and $13.3 million at March 31, 2015 and 2014, respectively, for additions to property, plant and equipment.
	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.  Such amounts represent primarily Hawaii state general excise taxes and Hawaii Public Utility Commission fees.  Such taxes and fees amounted to $2.0 million and $1.8 million for the three months ended March 31, 2015 and 2014, respectively.
	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 was as follows:
		Three Months Ended
		March 31,
		2015	2014
	Basic earnings per share - weighted average shares	10,692,198	10,528,039
	Effect of dilutive securities:
	Employee and director restricted stock units	73,457	124,012
	Warrants	507,267	619,776
	Diluted earnings per share - weighted average shares	11,272,922	11,271,827
	The computation of weighted average dilutive shares outstanding excluded grants of restricted stock units convertible into 86,608 shares of common stock for the three month periods ended March 31, 2014. The unrecognized compensation on a per unit basis for these restricted stock units was greater than the average market price of the Company’s common stock for the period presented. Therefore, the effect would be anti-dilutive.  For the three months ended March 31, 2015, there were no restricted stock units that were anti-dilutive to earnings per share.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued a new accounting standard which provides guidance for revenue recognition.  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 standard will be effective for the Company in the first quarter of 2017 and either full retrospective or modified retrospective adoption is permitted. Early adoption is not permitted. The Company is currently evaluating the impact of the adoption of this accounting standard on the Company’s financial position, results of operations and cash flows.
	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 with early adoption permitted. The Company is currently evaluating the impact of adoption of this accounting standard.
	In April 2015, the FASB issued an accounting standard simplifying the presentation of debt issuance costs.  The new standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability which is consistent with debt discounts. The standard requires retrospective adoption and will be effective beginning in the first quarter of 2017 for the Company. Early adoption is permitted. The Company is currently evaluating the impact and timing of adopting this new accounting standard.

	Noncurrent				$	288,863		$	289,423
	The term loan outstanding at March 31, 2015 provides for interest at the Alternate Base Rate, a rate which is indexed to the prime rate with certain adjustments as defined, plus a margin of 3.00% or a Eurocurrency rate on deposits of one, two, three or six months but no less than 1.00% per annum plus a margin of 4.00%.  The Company has selected the Eurocurrency rate as of March 31, 2015 resulting in an interest rate currently at 5.00%.
	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, 50% or 25% of excess cash flow, as defined.  The percent of excess cash flow required is dependent on the Company’s leverage ratio.  The excess cash flow payment due for the year ended December 31, 2014 was not significant.  The Company must also make prepayments on loans in the case of certain events such as large asset sales.
	The Company also 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 as of or for the periods ended March 31, 2015 and 2014.  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 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.
	The following provides the components of benefit costs (income) for the three months ended March 31, 2015 and 2014 (dollars in thousands):

	Interest cost	589			602
	Amortization of loss	149			15
	Net periodic benefit cost	$	997		$	847
	During the three months ended March 31, 2015, the Company’s pension plans paid lump-sum benefits to plan participants in full settlement of obligations due amounting to $6.6 million.  This resulted in the recognition of a loss on settlement for both the union and management pension plans amounting to $0.9 million for the three months ended March 31, 2015.  Because of the settlements, the Company measured its pension plan obligations and plan assets as of March 31, 2015 in determining its employee benefit obligations as of that date.  The Company used discount rates of 3.54% to 3.57% to measure the plan obligations as of that date.  Plan assets were measured at fair value also as of March 31, 2015.  The new measurement resulted in a charge to other comprehensive loss of $2.2 million for the three months ended March 31, 2015.
	The Company previously disclosed in its consolidated financial statements for the year ended December 31, 2014 that it expected to contribute $10.0 million to its pension plan in 2015.  As of March 31, 2015, the Company has contributed $2.0 million.  The Company presently anticipates contributing the full amount during the remainder of 2015.

	The Company recognized compensation expense of $0.4 million and $1.1 million for the three months ended March 31, 2015 and 2014, respectively.  The fair value as of the vesting date for the restricted stock units that vested during the three months ended March 31, 2015 and 2014 was $2.5 million and $2.7 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 35,714 and 34,573 for the three months ended March 31, 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 amounted to $0.9 million and $1.0 million for the three months ended March 31, 2015 and 2014, respectively.  Other than reimbursements for tax withholdings, there was no cash received under all share-based arrangements.  In March 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 the first quarter of 2014.

	Trans-Pacific Submarine Cable
	In August 2014, the Company entered into an agreement with several other telecommunication companies to build and operate a trans-Pacific submarine cable system.  The total system cost is expected to be $245 million and is primarily composed of a supply contract with the lead contractor.  The Company will contribute $25 million over the multi-year construction period for a fractional ownership in the system.  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 December 2016.  As of March 31, 2015, the Company had paid $2.3 million to the cable contractor for the cable build.
	The Company anticipates having excess capacity on its share of the trans-Pacific cable that it will make available to other carriers for a fee.  The Company is in the process of contracting 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 an agreement for the sale of capacity for $5.0 million.  As of March 31, 2015, the Company had received up-front payments, as provided for in the agreement, which are held in escrow amounting to $2.0 million.  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 assets in the condensed consolidated balance sheet.  A liability to provide services in the future for the same amount is included 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 work force.
	Third Party Claims
	In the normal course of conducting its business, the Company is involved in various disputes with third parties, including vendors and customers.  The outcome of such disputes is generally uncertain and subject to commercial negotiations.  The Company periodically assesses its liabilities in connection with these matters and records reserves for those matters where it is probable that a loss has been incurred and the loss can be reasonably estimated.  Based on management’s most recent assessment, the Company believes that the risk of loss in excess of liabilities recorded is not material for all outstanding claims and disputes and the ultimate outcome of such matters will not have a material adverse effect on the Company’s results of operations, cash flows or financial position.
	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 condensed consolidated financial statements.

Fair Value of Financial Instruments
Fair Value of Financial Instruments
	12.  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 is measured at Level 1.
	Investment securities — The fair value of investment securities is based on quoted market prices.  Investment securities are included in other assets on the condensed consolidated balance sheets.
	Debt — The fair value of debt is based on the value at which the debt is trading among holders.
	The estimated fair value of financial instruments is as follows (dollars in thousands):
		Carrying		Fair
		Value		Value
	March 31, 2015
	Assets - investment in U.S. Treasury obligations	$	811	$	811
	Liabilities - long-term debt (carried at cost)	291,863		296,496

	Assets - investment in U.S. Treasury obligations	$	808	$	808
	Liabilities - long-term debt (carried at cost)	292,423		296,908
	Fair Value Measurements
	Fair value for accounting purposes is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).
	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).
	Assets measured at fair value on a recurring basis represent investment securities included in other assets.  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):
		March 31,		December 31,
		2015		2014

	Supplemental Non-Cash Investing and Financing Activities
	Accounts payable included $15.2 million and $13.3 million at March 31, 2015 and 2014, respectively, for additions to property, plant and equipment.
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.  Such amounts represent primarily Hawaii state general excise taxes and Hawaii Public Utility Commission fees.  Such taxes and fees amounted to $2.0 million and $1.8 million for the three months ended March 31, 2015 and 2014, respectively.
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 was as follows:
		Three Months Ended
		March 31,
		2015	2014
	Basic earnings per share - weighted average shares	10,692,198	10,528,039
	Effect of dilutive securities:
	Employee and director restricted stock units	73,457	124,012
	Warrants	507,267	619,776
	Diluted earnings per share - weighted average shares	11,272,922	11,271,827
	The computation of weighted average dilutive shares outstanding excluded grants of restricted stock units convertible into 86,608 shares of common stock for the three month periods ended March 31, 2014. The unrecognized compensation on a per unit basis for these restricted stock units was greater than the average market price of the Company’s common stock for the period presented. Therefore, the effect would be anti-dilutive.  For the three months ended March 31, 2015, there were no restricted stock units that were anti-dilutive to earnings per share.
Recent Accounting Pronouncement
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued a new accounting standard which provides guidance for revenue recognition.  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 standard will be effective for the Company in the first quarter of 2017 and either full retrospective or modified retrospective adoption is permitted. Early adoption is not permitted. The Company is currently evaluating the impact of the adoption of this accounting standard on the Company’s financial position, results of operations and cash flows.
	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 with early adoption permitted. The Company is currently evaluating the impact of adoption of this accounting standard.
	In April 2015, the FASB issued an accounting standard simplifying the presentation of debt issuance costs.  The new standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability which is consistent with debt discounts. The standard requires retrospective adoption and will be effective beginning in the first quarter of 2017 for the Company. Early adoption is permitted. The Company is currently evaluating the impact and timing of adopting this new accounting standard.
