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, 2013.
	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 September 30, 2014 are held in one bank in demand deposit accounts.
	Supplemental Non-Cash Investing and Financing Activities
	Accounts payable included $15.1 million and $6.2 million at September 30, 2014 and 2013, 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 $1.9 million and $5.5 million for the three and nine months ended September 30, 2014 and $1.9 million and $5.6 million for the three and nine months ended September 30, 2013, 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		Nine Months Ended
		September 30,		September 30,
		2014	2013	2014	2013
	Basic earnings per share - weighted average shares	10,586,690	10,337,488	10,567,036	10,321,905
	Effect of dilutive securities:
	Employee and director restricted stock units	122,530	173,405	153,752	166,461
	Warrants	602,471	695,266	608,540	607,811
	Diluted earnings per share - weighted average shares	11,311,691	11,206,159	11,329,328	11,096,177
	No restricted stock units were deemed anti-dilutive and excluded from the computation of diluted earnings per share for the three and nine months ended September 30, 2014 and 2013.
	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 consolidated financial statements.
	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 adoption of this standard is not expected to impact the consolidated financial statements.

	3.  SystemMetrics Corporation Acquisition
	On September 30, 2013, the Company completed its acquisition of all of the voting stock of SystemMetrics Corporation (“SystemMetrics”) for $16.3 million in cash, net of cash acquired and purchase price adjustments.  Of the total purchase price, $11.9 million was paid at closing with the balance subject to an earn-out over a three year period.  Payment of the earn-out is contingent on SystemMetrics meeting certain performance metrics and continued employment of the SystemMetrics’ key executive.  For financial reporting purposes, the earn-out is accounted for as compensation expense as earned.
	SystemMetrics provides virtual and physical data center colocation services in the State of Hawaii along with other telecommunication services that are complementary to the Company’s operations.
	The Company followed the acquisition method of accounting and allocated the purchase price to the tangible and intangible assets acquired and liabilities assumed based on their provisional fair values, and the estimates and assumptions were subject to change within the measurement period.  There were no changes made to the allocation of the purchase price in 2014.  The measurement period was considered closed as of June 30, 2014.
	For the three months ended September 30, 2014, SystemMetrics revenue amounted to $2.5 million and the net loss amounted to $0.2 million.  For the nine months ended September 30, 2014, SystemMetrics revenue amounted to $7.2 million and the net loss was $0.4 million.
	The following unaudited pro forma results of operations are provided for the three and nine months ended September 30, 2013 as if the acquisition of SystemMetrics occurred on January 1, 2012.  The pro forma combined results of operations have been prepared by adjusting the historical results of the Company to include the historical results of SystemMetrics.  Adjustments were made to the historical results for the purchase price allocation to adjust depreciation and amortization, to eliminate the interest on certain debt financing which was not assumed in the purchase, to eliminate certain intercompany revenue between the entities and to reallocate the transaction related expenses from the 2013 to the 2012 periods.
	These supplemental pro forma results of operations are provided for illustrative purposes only and do not purport to be indicative of the actual results that would have been achieved by the combined company for the periods presented or that may be achieved by the combined company in the future.  The pro forma results of operations do not include any costs savings or synergies that resulted, or will result, from the acquisition or any estimated costs that will be incurred to integrate SystemMetrics.  Future results may vary significantly from the results reflected in this pro forma financial information because of future events and transactions as well as other factors.
	The pro forma results are as follows (dollars in thousands):

	In February 2013, the Company entered into an agreement to sell a parcel of land and warehouse not actively used in the Company’s operations for a purchase price, as amended, of $13.9 million. The sale was subject to due diligence by the buyer and approval of the Hawaii Public Utilities Commission (“HPUC”). The HPUC approval was received in May 2013 and the sale was consummated in June 2013. The net proceeds, net of commissions and other costs paid through escrow of $0.8 million, amounted to $13.1 million. A gain on the sale of $6.5 million was recognized in the second quarter of 2013 as management concluded the land sold was not grouped with the assets subject to the composite depreciation method. The HPUC approval requires the Company to spend $0.3 million on training employees on broadband telecommunication deployment and operation. In addition, the HPUC approval provides for the Company to make improvements to its broadband network in an amount equal to the net proceeds less the training cost commitment. The planned training expenses and network capital spending are being recognized as the costs are incurred.

	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.  No excess cash flow payment was due for the year ended December 31, 2013.  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 matures on October 3, 2015.  The facility has an available balance of $30.0 million with no amounts drawn as of or for the periods ended September 30, 2014 and 2013.  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.
	Refinancing
	In June 2013, the Company refinanced its term loan debt. The Company paid a premium on the repayment of the old term loan of $3.0 million. In addition, the Company paid $3.4 million in underwriting fees and legal costs. The premium on repayment of debt, existing original issue discount, existing deferred financing costs, underwriting fees and legal costs were accounted for in accordance with accounting standards for modification of debt instruments with different terms. The Company compared each syndicated lenders’ loan under the old term loan with the syndicated lenders’ loan under the new term loans. For loans under the new term loan that were substantially different, the Company recognized the exchange of debt instruments as a debt extinguishment. For loans under the new term loan that were not substantially different, the Company accounted for the exchange of debt instruments as a modification. As a result of the refinancing, the Company deferred $2.7 million of financing related costs and recognized a loss on early extinguishment of debt of $3.7 million.

	Trans-Pacific Submarine Cable
	In August 2014, the Company joined several other telecommunication companies to form a consortium 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 invest $25 million over the multi-year construction period for a fractional ownership in the system.  The investment is expected to be $2.5 million in 2014, $10.2 million in 2015, $10.5 million in 2016 and $1.8 million in 2017.  In addition, the Company will construct a cable landing station in Hawaii and provide cable landing services in exchange for additional system capacity.  The value of this capacity is estimated at $5.0 million.  The system is expected to be operational in December 2016.
	Power Purchase Agreement
	In July 2014, the Company entered into a power purchase agreement to acquire all of the power generated from solar photovoltaic systems that are to be installed by a third party on selected company properties.  The agreement provides for all power generated to be purchased at a fixed price over a 25 year term.  Based on planned solar installations and expected power generated, the Company estimates it will purchase power amounting to $0.7 million in 2015.  Power purchased in future years will be dependent on the level of photovoltaic units installed by the third party and the power generated.
	Tropical Storm Iselle
	On August 8, 2014, Tropical Storm Iselle made landfall in the State of Hawaii with the most significant damage occurring on the east side of the island of Hawaii.  The cost of replacement of the Company’s damaged outside plant is estimated to amount to $2.5 million as of September 30, 2014.  The Company is insured but there are limitations based on proximity of poles and lines to other Company property and based on deductibles determined by insured location as well as by event.  As of September 30, 2014, the Company has not recognized a recovery in the condensed consolidated financial statements.  The expense attributed to the storm recognized in the condensed consolidated statements of income after cost capitalization amounted to $0.9 million for the three and nine months ended September 30, 2014.
	Puna Lava Flow
	A lava flow from Kilauea volcano is impacting the Puna district on the island of Hawaii.  The Company has been monitoring the progress of the lava flow and has contingency plans to reduce disruption to its services in the area.  These plans are subject to change depending on the direction and advancement of the lava flow which has been unpredictable.  It is not possible at this time to estimate what loss, if any, to Company facilities will be incurred as a result of the lava flow.
	Collective Bargaining Agreement
	The Company has a collective bargaining agreement with the International Brotherhood of Electrical Workers Local 1357 (“IBEW”) with an effective date of January 1, 2013 for a term of five years.  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.

	13.  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
	September 30, 2014
	Assets - investment in U.S. Treasury obligations	$	807	$	807

	Liabilities - long-term debt (carried at amortized cost)	294,679		299,886
	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):
		September 30,		December 31,

Segment Information	'
	14.  Segment Information
	The Company operates in two reportable segments of telecommunications and data center colocation.  This conclusion is based on how resources are allocated and performance is assessed by the Chief Executive Officer, the Company’s chief operating decision maker.  The telecommunications segment provides local voice services, long distance voice services, high-speed internet and video.  In addition, the segment provides network access which includes data transport.  Various related telephony services are provided including equipment and managed services.  The data center colocation segment provides physical colocation, virtual colocation and various related telephony services.
	In the fourth quarter of 2013, the Company reevaluated its reportable segments.  This was prompted by the acquisition of SystemMetrics and the Company’s current strategic focus.  Previously, the Company presented a wireline and other segment (which was primarily wireless services).  With the diminishing significance of the wireless segment, the Company no longer provides separate wireless information to the Company’s chief operating decision maker.  Both these segments are now combined into the telecommunications segment.  Prior to the acquisition of SystemMetrics on September 30, 2013, the Company did not have data center colocation operations.  Hence, the Company had a single reportable segment prior to September 30, 2013 under the revised reportable segment structure.
	The following table provides operating financial information for the Company’s reportable segments for the three and nine months ended September 30, 2014 (dollars in thousands):

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		Nine Months Ended
		September 30,		September 30,
		2014	2013	2014	2013

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 consolidated financial statements.
	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 adoption of this standard is not expected to impact the consolidated financial statements.
