	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. 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 financial position, the results of operations 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, 2012.
	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, 2013 are held in one bank in demand deposit accounts.
	Supplemental Non-Cash Investing and Financing Activities
	Accounts payable included $6.2 million and $2.4 million at September 30, 2013 and 2012, 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 HPUC fees.  Such taxes and fees amounted to $1.9 million and $5.6 million for the three and nine months ended September 30, 2013 and $1.6 million and $5.3 million for the three and nine months ended September 30, 2012, 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,
		2013	2012	2013	2012
	Basic earnings per share - weighted average shares	10,337,488	10,246,335	10,321,905	10,230,719
	Effect of dilutive securities:
	Employee and director restricted stock units	173,405	124,301	166,461	124,871
	Warrants	695,266	337,818	607,811	302,927
	Diluted earnings per share - weighted average shares	11,206,159	10,708,454	11,096,177	10,658,517
	The computation of weighted average dilutive shares outstanding excluded restrictive stock units to acquire 18,610 shares and 18,612 shares of common stock for the three and nine month period ended September 30, 2012, respectively.  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.  There was no such exclusion for the three and nine month periods ended September 30, 2013.

	3.  Acquisitions
	SystemMetrics Corporation
	On September 30, 2013, the Company completed its acquisition of all of SystemMetrics Corporation (“SystemMetrics”) common stock for $16.3 million.  Of the total purchase price, $11.9 million was payable at closing, net of cash acquired and purchase price adjustments.  A balance of $3.3 million is 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.  The purchase transaction has been accounted for as a business combination.  For financial reporting purposes, the earn-out will be 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.  Transaction costs amounted to $0.4 million.  These costs were primarily professional fees and recognized as general and administrative expenses as incurred.
	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 preliminary fair values, and the estimates and assumptions are subject to change within the measurement period, which is one year from the acquisition date. The excess of the purchase price over those fair values was recorded as goodwill.  The following table summarizes the assets acquired and the liabilities assumed (dollars in thousands):
	Assets -
	Property and equipment	$	3,781
	Intangible assets	4,380
	Goodwill	10,368
	Other assets	643
		19,172
	Liabilities -
	Current liabilities	3,684
	Non-current liabilities	2,304
	Deferred income taxes	1,326
		7,314
	Net acquisition price	$	11,858
	Because the acquisition occurred on September 30, 2013, the financial results of SystemMetrics had no impact on the Company’s consolidated statements of income for the three or nine months ended September 30, 2013.
	The fair value of property, plant and equipment was based on the highest and best use of the specific properties.  To determine fair value the Company considered and applied primarily the cost approach.  This approach considers the amount required to construct or purchase a new asset of equal utility at current prices with adjustments to the value for physical deterioration, functional obsolescence and economic obsolescence.  The fair value of intangible assets including the brand name and customer relationship intangibles were based on discounted cash flows from projections of results of operations for SystemMetrics.
	The goodwill recognized is attributed to the anticipated synergies to be achieved by combining the operations of the Company and SystemMetrics.  The goodwill is not deductible for income tax reporting purposes and is anticipated to be attributed to a newly formed data center segment.
	The following unaudited pro forma results of operations are provided for the three and nine months ended September 30, 2013 and 2012 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 which primarily impacts 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):
		For the Three Months Ended						For the Nine Months Ended
		September 30,						September 30,
		2013			2012			2013			2012

	Wavecom Solutions Corporation
	On December 31, 2012, the Company completed its acquisition of Wavecom Solutions Corporation (“Wavecom”) for $8.7 million in cash, net of cash acquired and final purchase adjustments.  Wavecom provides telecommunication services in the State of Hawaii which 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 preliminary fair values, and the estimates and assumptions are subject to change within the measurement period, which is one year from the acquisition date. The measurement period remains open as of September 30, 2013 as the Company continues to evaluate additional information obtained related to the amount recognized for certain estimated liabilities. The excess of the purchase price over those fair values was recorded as goodwill.  During the three months ended March 31, 2013, the Company made adjustments to the preliminary purchase price allocation based on additional information as to the existence and value of certain assets.  In addition, the net acquisition price changed with the final purchase adjustments agreed to by the seller.  The measurement period adjustments did not have a significant impact on the Company’s condensed consolidated statements of income for the nine months ended September 30, 2013. In addition, these adjustments did not have a significant impact on the Company’s consolidated balance sheets as of December 31, 2012. Therefore, the Company has not retrospectively adjusted the comparative 2012 financial information presented herein.  The adjustments are as follows (dollars in thousands):
								Recognized

	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 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 will be recognized as the costs are incurred.
	In January 2013, the Company entered into an agreement to sell most of its radio towers for $3.6 million.  The sale was subject to due diligence by the buyer.  In November 2013, the buyer, as a result of a change in its ownership, issued a termination notice of the purchase per the provisions of the agreement.

	With the acquisition of SystemMetrics, the Company recognized customer relationship intangibles of $3.6 million with a useful life of 13 years and a trade name of $0.1 million with a useful life of four years.  The determination of useful lives for customer relationships was based on historical and expected customer attrition rates.  The Company will use an accelerated amortization method reflecting the rate of expected customer attrition.
	In conjunction with the acquisition of Wavecom, the Company adjusted the carrying value of goodwill in the first quarter of 2013 as further discussed in Note 3.  The revised goodwill amounted to $1.4 million and is included in the wireline segment.  In conjunction with the acquisition of SystemMetrics, the Company recognized goodwill of $10.4 million which is expected to be attributed to the data center colocation services segment.

	Current				3,000			3,000
	Noncurrent				$	292,248		$	292,410
	The term loan outstanding at September 30, 2013 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 September 30, 2013 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 for prepayment is dependent on the Company’s leverage ratio.  The excess cash flow prepayment for the year ended December 31, 2012 amounted to $2.1 million and was paid in March 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 ending September 30, 2013 and 2012.  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 2013
	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.
	Refinancing 2012
	In connection with the February 2012 refinancing of the term loan debt, the Company paid a premium on the repayment of the old term loan of $6.0 million.  In addition, the Company paid $4.1 million in underwriting fees and legal costs. The premium on repayment of debt, and 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 capitalized $5.0 million of the premium on the repayment of debt and refinancing fees and expensed the remainder resulting in a loss on early extinguishment of debt of $5.1 million.

	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 Company amended its union pension plan on January 24, 2012 for the freeze of benefits effective March 1, 2012.  This resulted in a reduction of the projected benefit obligation by $30.2 million which is the difference between the accumulated benefit obligation and projected benefit obligation at that date.  The liability as of January 24, 2012 was measured using a discount rate of 4.54%.  The union pension trust assets were also measured as of this date.  The reduction in the net recorded liability of $33.4 million was used to offset actuarial losses previously recognized in accumulated other comprehensive loss.
	The Company accrues the 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 for the three and nine months ended September 30, 2013 and 2012 (dollars in thousands):

	Through December 31, 2012, the Company maintained a full valuation allowance over its net deferred income tax assets.  Based on consistent earnings after its 2010 emergence from Chapter 11 through December 31, 2012, the Company released its valuation allowance as of that date.  For the three months and nine months ended September 30, 2012, the existence of the full valuation allowance resulted in an income tax benefit reflecting certain tax credits.
	The Company evaluates its tax positions for liability recognition.  As of September 30, 2013, the Company had no unrecognized tax benefits.  No interest or penalties related to tax assessments were recognized in the Company’s condensed consolidated statements of income for the three and nine months ended September 30, 2013 or 2012.  All tax years from 2009 remain open for both federal and Hawaii state purposes.
	On September 13, 2013, the Treasury Department and the Internal Revenue Service issued regulations that provide guidance with respect to the treatment of materials and supplies, capitalization of amounts paid to acquire or produce tangible property, and the determination of whether an expenditure with respect to tangible property is a deductible repair or must be capitalized.  The Company evaluated the impact of the new regulations and concluded that the new regulations will not have a significant impact on its consolidated financial statements.

	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

	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 the 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 as 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, 2013
	Assets - investment in U.S. Treasury obligations (Level 1)	$	891	$	891

	Liabilities - long-term debt (carried at amortized cost, Level 2)	295,410		302,000
	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 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,
		2013		2012

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,
		2013	2012	2013	2012
	Basic earnings per share - weighted average shares	10,337,488	10,246,335	10,321,905	10,230,719
	Effect of dilutive securities:
	Employee and director restricted stock units	173,405	124,301	166,461	124,871
	Warrants	695,266	337,818	607,811	302,927
	Diluted earnings per share - weighted average shares	11,206,159	10,708,454	11,096,177	10,658,517
	The computation of weighted average dilutive shares outstanding excluded restrictive stock units to acquire 18,610 shares and 18,612 shares of common stock for the three and nine month period ended September 30, 2012, respectively.  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.  There was no such exclusion for the three and nine month periods ended September 30, 2013.
