	Organization and Significant Accounting Policies
	Business — USA Mobility, Inc. and its subsidiaries (collectively, “USA Mobility” or the “Company”), through its indirect wholly owned subsidiary, USA Mobility Wireless, Inc. (“wireless operations”) is a leading provider of wireless messaging, mobile voice and data and unified communications solutions in the United States. We provide one-way and two-way messaging services. One-way messaging consists of numeric and alphanumeric messaging services. Numeric messaging services enable subscribers to receive messages that are composed entirely of numbers, such as a phone number, while alphanumeric messages may include numbers and letters which enable subscribers to receive text messages. Two-way messaging services enable subscribers to send and receive messages to and from other wireless messaging devices, including pagers, personal digital assistants and personal computers. We also offer voice mail, personalized greeting, message storage and retrieval and equipment loss and/or maintenance protection to both one-way and two-way messaging subscribers. These services are commonly referred to as wireless messaging and information services.
	In addition, the Company, through its indirect wholly owned subsidiary, Amcom Software, Inc. (“Amcom” or “software operations”), provides mission critical unified communications solutions for contact centers, emergency management, mobile event notification and Smartphone messaging. The combined product offering is capable of addressing a customer’s mission critical communication needs. Amcom delivers software solutions, which enable seamless critical communications. Amcom’s unified communications suite (includes solutions for contact centers, emergency management, mobile event notification, and messaging) connects people across a changing complement of communication devices.
	Effective January 1, 2014 Amcom Software, Inc. was merged into USA Mobility Wireless, Inc. The Company has and is undertaking the consolidation of wireless and software operation activities and functions.
	Organization and Principles of Consolidation — We are a holding company formed to effect the merger of Arch Wireless, Inc. and subsidiaries (“Arch”) and Metrocall Holdings, Inc. and subsidiaries (“Metrocall”), which occurred on November 16, 2004. Prior to the merger, we had conducted no operations other than those incidental to our formation. On March 3, 2011, we acquired Amcom.
	The accompanying consolidated financial statements include our accounts and the accounts of our wholly owned direct and indirect subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. We have an investment in a Canadian company that is 10% owned and is accounted for under the cost method of accounting.
	Preparation of Financial Statements — Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Amounts shown on the consolidated statements of income within the operating expense categories of cost of revenue; service, rental and maintenance; selling and marketing; and general and administrative are recorded exclusive of severance and restructuring, depreciation, amortization and accretion and impairment. These items are shown separately on the consolidated statements of income within operating expenses. Foreign currency translation adjustments were immaterial and were not presented separately in our consolidated statements of stockholders’ equity and balance sheets, and consequently no statements of comprehensive income are presented.
	All adjustments are of a normal recurring nature except for adjustments related to the acquisitions. The statements of income and the estimated fair value of the assets acquired and liabilities assumed have been included in our consolidated financial statements from the dates of the acquisitions.
	Use of Estimates — The preparation of these consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. On an on-going basis, we evaluate estimates and assumptions, including but not limited to those related to the impairment of long-lived assets, intangible assets subject to amortization and goodwill, accounts receivable allowances, revenue recognition, depreciation expense, asset retirement obligations, severance and restructuring and income taxes. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
	Impairment of Long-Lived Assets, Intangible Assets Subject to Amortization and Goodwill — We are required to evaluate the carrying value of our long-lived assets, amortizable intangible assets and goodwill. Amortizable intangible assets include customer related intangibles, technology based intangibles, contract based intangibles and marketing intangibles that primarily resulted from our acquisition of Amcom in 2011 and IMCO in 2012. Such intangibles are amortized over periods ranging from two to fifteen years. We assess whether circumstances exist which suggest that the carrying value of long-lived assets may not be recoverable. When applicable, we assess the recoverability of the carrying value of our long-lived assets and certain amortizable intangible assets based on estimated undiscounted cash flows to be generated from such assets. In assessing the recoverability of these assets, we forecast estimated enterprise-level cash flows based on various operating assumptions such as revenue forecasted by product line and in-process research and development cost. If the forecast of undiscounted cash flows does not exceed the carrying value of the long-lived assets, we would record an impairment charge to the extent the carrying value exceeded the fair value of such assets.
	Goodwill resulting from our acquisitions is not amortized but is evaluated for impairment at least annually, or when events or circumstances suggest a potential impairment has occurred. We have selected the fourth quarter to perform this annual impairment test. We will evaluate goodwill for impairment between annual tests if indicators of impairment exist. GAAP requires the comparison of the fair value of the reporting unit to the carrying amount to determine if there is potential impairment. For this determination, all of our goodwill has been assigned to our software operations, which is also deemed to be the reporting unit. The first step of the impairment test involves comparing the fair values of the reporting unit with its carrying values. If the reporting unit’s fair value is less than the carrying amount of the reporting unit, we perform the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill. The amount, by which the implied fair value is less than the carrying value of the goodwill, if any, is recognized as an impairment loss. The fair value of the reporting unit is estimated using a discounted cash flow methodology. This analysis requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, estimation of the useful life over which cash flows will occur, and determination of our weighted average cost of capital. We also consider the market value of our invested capital as a confirmatory measurement of fair value.
	We did not record any impairment of long-lived assets, amortizable intangible assets and goodwill for the years ended December 31, 2013 and 2011. We recorded an impairment charge of $3.4 million to the contract-based intangible assets for our software operations for the year ended December 31, 2012. All other long-lived assets, amortizable intangible assets and goodwill were not deemed to be impaired for the year ended December 31, 2012.
	Accounts Receivable Allowances — Our two most significant allowance accounts are: an allowance for doubtful accounts and an allowance for service credits. Provisions for these allowances are recorded on a monthly basis and are included as a component of general and administrative expenses and a reduction of revenue, respectively.
	Estimates are used in determining the allowance for doubtful accounts and are based on historical collection experience and current and forecasted trends. In determining these percentages, we review historical write-offs, including comparisons of write-offs to provisions for doubtful accounts and as a percentage of revenues. We compare the ratio of the allowance to gross receivables to historical levels, and monitor amounts collected and related statistics. The allowance for doubtful accounts for both our wireless operations and software operations was $1.3 million and $1.2 million (of which $0.7 million and $0.6 million related to software operations) at both December 31, 2013 and 2012, respectively. We write off receivables when they are deem uncollectible. While write-offs of customer accounts have historically been within our expectations and the provisions established, we cannot guarantee that future write-off experience will be consistent with historical experience, which could result in material differences in the allowance for doubtful accounts and related provisions.
	The allowance for service credits and related provisions for wireless operations is based on historical credit percentages, current credit and aging trends and actual credit experience. We analyze our past credit experience over several time frames. Using this analysis along with current operational data including existing experience of credits issued and the time frames in which credits are issued, we establish an appropriate allowance for service credits. The allowance for service credits for wireless operations were $0.3 million and $0.4 million at December 31, 2013 and 2012, respectively. While credits issued have been within our expectations and the provisions established, we cannot guarantee that future credit experience will be consistent with historical experience, which could result in material differences in the allowance for service credits and related provisions.
	Other allowance accounts for wireless operations totaled $0.4 million at both December 31, 2013 and 2012, respectively. The primary component of these allowance accounts reduces accounts receivable for lost and non-returned pagers to the expected realizable amounts. We base this allowance on historical payment trends. The other allowance for software operations totaled $0.2 million and $0.1 million at December 31, 2013 and 2012, respectively. This allowance reduces maintenance revenue based on historical actual payment trends and aging trends experience.
	Revenue Recognition — We recognize revenue when four basic criteria have been met: (1) persuasive evidence of an arrangement exists, (2) delivery has occurred or services rendered, (3) the fee is fixed or determinable and (4) collectability is reasonably assured. Amounts billed to customers but not meeting these revenue recognition criteria are deferred until all four criteria have been met.
	Our wireless operations’ revenue consists primarily of service rental and maintenance fees charged to customers on a monthly, quarterly, or annual basis. Revenue also includes the sale of messaging devices directly to customers and other companies that resell our services. With respect to revenue recognition for multiple deliverables, we evaluated these revenue arrangements and determined that two separate units of accounting exist, paging service revenue and product sales. We recognize paging service revenue over the period the service is performed; revenue from product sales is recognized at the time of shipment or installation. We have a variety of billing arrangements with our customers resulting in deferred revenue from advance billings and accounts receivables for billing in-arrears arrangements.
	For our software operations, we enter into contractual arrangements that include a fee that is fixed or determinable. This contractual arrangement has been agreed to by the customer and we review customer creditworthiness to assure collectability.
	Our software operations’ revenue consists primarily of the sale of software (license fees), professional services (primarily installation and training), equipment (to be used in conjunction with the software) and maintenance support (post-contract support). The software is licensed to end users under an industry standard software license agreement. Our software products are considered to be “off-the-shelf software” as the software is marketed as a stock item that customers can use without customization.
	For purposes of disclosure, revenue from the software operations consists of two primary components: (1) operations revenue consisting of software license revenue, professional services revenue and equipment sales, and (2) maintenance revenue.
	We generally sell software licenses, professional services, equipment and maintenance in multiple-element arrangements. At inception of the arrangement, we allocate the arrangement consideration to the software deliverables (software licenses, professional services and maintenance) as a group and to the non-software deliverables (equipment and maintenance on equipment, when applicable) using the relative selling price method. When performing this allocation, the estimated selling price for each deliverable is based on vendor specific objective evidence of fair value (“VSOE”), third party evidence of fair value (“TPE”), or if VSOE and TPE are not available, the best estimated selling price (“BESP”) for selling the element on a stand-alone basis. We have determined that TPE is not a practical alternative due to differences in our service offerings compared to other parties and the availability of relevant third-party pricing information. The amount of revenue allocated to delivered items is limited by contingent revenue, if any.
	Post contract support is allocated using VSOE as an input in the relative selling price allocation. For software licenses, professional services and equipment we have determined that neither VSOE nor TPE is available and as such, we have used BESP as an input in order to allocate our arrangement fees. We determine BESP by considering our overall pricing objectives and market conditions. Significant pricing practices take into consideration our discounting practices, the size and volume of our transactions, the customer demographic, the geographic area where our services are sold, our price lists, our go-to-market strategy, historical standalone sales and contract prices. The determination of BESP is made through consultation with and approval by management, taking into consideration the go-to-market strategy. As our go-to-market strategies evolve, we may modify our pricing practices in the future, which could result in changes in relative selling prices, including both VSOE and BESP.
	In multiple-element arrangements, the arrangement consideration allocated to our non-software deliverables (equipment) is generally recognized upon delivery to the customer.
	For our software deliverables, which include software licenses, professional services, and post contract support, we further allocate arrangement consideration using the residual method. As noted above, we have not established VSOE for our software licenses and professional services. However, we have established, and continue to maintain, VSOE for post contract support. As such, the residual amount relating to the revenue from software licenses and professional services is recognized as revenue over the period of delivery to the customer, if known, or when fully delivered to the customer. Maintenance revenue is deferred and recognized over the maintenance period, generally one year.
	Long-Lived Assets — Leased messaging devices sold or otherwise retired were removed from the accounts at their net book value using the weighted-average method. Property and equipment are reported at cost. Property and equipment is depreciated using the straight-line method over the following estimated useful lives:
		Estimated Useful
		Life
	Asset Classification	(In Years)
	Buildings	20
	Leasehold improvements	3 or lease term
	Messaging devices	2-Jan
	Paging and computer equipment	5-Jan
	Furniture and fixtures	5-Mar
	Vehicles	3
	We calculate depreciation on certain of our paging equipment assets using the group life method; accordingly, ordinary asset retirements and disposals are charged against accumulated depreciation with no gain or loss recognized.
	Asset Retirement Obligations — We recognized liabilities and corresponding assets for future obligations associated with the retirement of assets. We have paging equipment assets, principally transmitters, which are located on leased locations. The underlying leases generally require the removal of equipment at the end of the lease term; therefore, a future obligation exists (see Note 3).
	Severance and Restructuring — We continually evaluate our staffing levels to meet our business objectives for both the wireless and software operations and our strategy to reduce cost in our wireless operations in line with the declining revenue and subscriber base. Severance costs are reviewed periodically to determine whether a severance charge is required due to employers’ accounting for post-employment benefits. We are required to accrue post-employment benefits if certain specified criteria are met. Post-employment benefits include salary continuation, severance benefits and continuation of health insurance benefits.
	From time to time, we will announce reorganization plans that may include eliminating positions. Each plan is reviewed to determine whether a restructuring charge is required to be recorded related to costs associated with exit or disposal activities. We are required to record an estimate of the fair value of any termination costs based on certain facts, circumstances and assumptions, including specific provisions included in the underlying reorganization plan.
	Also from time to time, we cease to use certain facilities, such as office buildings and transmitter locations, including available capacity under certain agreements, prior to expiration of the underlying contractual agreements. Exit costs based on certain facts, circumstances and assumptions, including remaining minimum lease payments, potential sublease income and specific provisions included in the underlying contract or lease agreements are reviewed in each of these circumstances on a case-by-case basis to determine whether a restructuring charge is required to be recorded.
	Subsequent to recording such accrued severance and restructuring liabilities, changes in market or other conditions may result in changes to assumptions upon which the original liabilities were recorded that could result in an adjustment to the liabilities and, depending on the circumstances, such adjustment could be material (see Note 14).
	Income Taxes — We file a consolidated U.S. Federal income tax return and income tax returns in state, local and foreign jurisdictions (principally Canada and Australia) as required. The provision for current income taxes is calculated and accrued on income and expenses expected to be included in current year U.S. and foreign income tax returns. The provision for current income taxes may also include interest, penalties and an estimated amount reflecting uncertain tax positions.
	Deferred income tax assets and liabilities are computed based on temporary differences between the financial statement values and the tax basis of assets and liabilities including net operating loss and tax credit carryforwards at the enacted tax rates expected to apply to taxable income when taxes are actually paid or recovered. Changes in deferred income tax assets and liabilities are included as a component of deferred income tax expense. Deferred income tax assets represent amounts available to reduce future income taxes payable. We provide a valuation allowance when we consider it “more likely than not” (greater than a 50% probability) that a deferred income tax asset will not be fully recovered. Adjustments to the valuation allowance are a component of the deferred income tax expense.
	Assets and liabilities are established for uncertain tax positions taken or positions expected to be taken in income tax returns when such positions fail to meet the “more likely than not” threshold based on the technical merits of the positions. Estimated interest and penalties related to uncertain tax positions are included as a component of income tax expense. We assess whether previously unrecognized tax benefits may be recognized when the tax position is (1) more likely than not of being sustained based on its technical merits, (2) effectively settled through examination, negotiation or litigation, or (3) settled through actual expiration of the relevant tax statutes. At December 31, 2013 and 2012, there were no uncertain tax positions.
	Research and Product Development — Development costs incurred in the research and development of new software products and enhancements to existing software products for external use are expensed as incurred until technological feasibility has been established. Costs incurred after technological feasibility is established and before the product is ready for general release would be capitalized. Costs eligible for capitalization were not material to the consolidated financial statements and were expensed as incurred to service, rental and maintenance expense.
	Shipping and Handling Costs — We incur shipping and handling costs to send and receive messaging devices to/from our wireless operations’ customers and shipping costs related to equipment sales in our software operations. These costs are expensed as incurred and included in general and administrative expenses for wireless operations and costs of revenue for software operations. Total shipping costs were $0.6 million, $0.8 million and $1.0 million for the years ended December 31, 2013, 2012 and 2011, respectively, for wireless operations and $0.3 million, $0.4 million and $0.5 million for the years ended December 31, 2013, 2012 and 2011, respectively, for software operations.
	Advertising Expenses — Advertising costs are charged to operations when incurred because they occur in the same period as the benefit is derived. These costs are included in selling and marketing expenses. We do not incur any direct response advertising costs. Advertising expenses were $65,000, $32,000 and $26,000 for the years ended December 31, 2013, 2012 and 2011, respectively, for wireless operations and $1.0 million, $0.8 million and $0.3 million for the years ended December 31, 2013, 2012 and 2011, respectively, for software operations.
	Stock Based Compensation — Compensation expense associated with common stock, restricted stock units (“RSUs”) and shares of restricted common stock (“restricted stock”) is recognized over the instruments’ vesting period based on the fair value of the related instruments.
	Cash Equivalents — Cash equivalents include short-term, interest-bearing instruments purchased with initial or remaining maturities of three months or less.
	Sales and Use Taxes — Sales and use taxes imposed on the ultimate consumer are excluded from revenue where we are required by law or regulation to act as collection agent for the taxing jurisdiction.
	Fair Value of Financial Instruments — Our financial instruments include our cash, letters of credit (“LOCs”), accounts receivable and accounts payable. The fair value of cash, accounts receivable and accounts payable are equal to their carrying values at December 31, 2013 and 2012.
	Earnings Per Common Share — The calculation of earnings per common share is based on the weighted-average number of common shares outstanding during the applicable period. The calculation for diluted earnings per common share recognizes the effect of all potential dilutive common shares that were outstanding during the respective periods, unless the impact would be anti-dilutive (see Note 6).
	Recent and New Accounting Pronouncements — Accounting pronouncements issued or effective during the year ended December 31, 2013 are not applicable to us or are not anticipated to have a material effect on our financial position or statement of income.

	On May 2, 2012, we acquired certain assets and technology from IMCO for a total estimated consideration of $3.7 million. During 2012, we increased goodwill by $2.1 million and intangible assets by $1.4 million for this acquisition. The intangible assets are being amortized over a four year period. During the fourth quarter of 2012, we reassessed the projected royalty payments to IMCO and reduced the expected future liabilities by $0.2 million based on recent data. During the fourth quarter of 2013, we reassessed the projected royalty payments to IMCO and further reduced the expected future liabilities by $0.2 million. During the year ended December 31, 2013, we paid $18,000 in royalties to IMCO.

	Long-Lived Assets
	The total depreciation, amortization and accretion expenses related to property and equipment, amortizable intangible assets, and asset retirement obligations for the years ended December 31, 2013, 2012, and 2011 were $9.6 million, $11.2 million and $14.0 million, respectively, for wireless operations; and $5.6 million, $7.0 million and $5.3 million for software operations for the years ended December 31, 2013, 2012 and 2011, respectively. The consolidated balances consisted of the following for the periods stated:
		For the Year Ended December 31,
		2013				2012				2011
		(Dollars in thousands)
	Depreciation	$	9,664			$	11,054			$	13,253
	Amortization	4,965				6,411				5,274
	Accretion(1)	538				767				807
	Total depreciation, amortization and accretion	$	15,167			$	18,232			$	19,334
	(1)	Accretion expense included $(29,000) in 2013 and $29,000 in 2012 in software operations related to the IMCO acquisition.
	Property and Equipment — A component of depreciation expense for wireless operations relates to the depreciation of certain of our paging equipment assets. The primary component of these assets are transmitters. For the years ended December 31, 2013, 2012 and 2011, $1.1 million, $1.9 million, and $3.3 million, respectively, of total wireless operations’ depreciation expense related to these assets. The components of depreciation expense for software operations relate primarily to computer equipment and leasehold improvements which were $0.8 million, $0.8 million and $0.3 million, respectively, for the years ended December 31, 2013, 2012 and 2011.
	Transmitter assets are grouped into tranches based on our transmitter decommissioning forecast and are depreciated using the group life method on a straight-line basis. Depreciation expense is determined by the expected useful life of each tranche of the underlying transmitter assets. The expected useful life is based on our forecasted usage of those assets and their retirement over time and aligns the useful lives of these transmitter assets with their planned removal from service. This rational and systematic method matches the underlying usage of these assets to the underlying revenue that is generated from these assets.
	Depreciation expense for these assets is subject to change based upon revisions in the timing of transmitter deconstruction resulting from our long-range planning and network rationalization process. During the fourth quarter of 2013, we completed a review of the estimated useful life of our transmitter assets (that are part of paging and computer equipment.) This review was based on the results of our long-range planning and network rationalization process and indicated that the expected useful life of the last tranche of the transmitter assets was no longer appropriate. As a result of that review, the expected useful life of the final tranche of transmitter assets was extended from 2017 to 2018. This change has resulted in a revision of the expected future depreciation expense for the transmitter assets beginning in the fourth quarter of 2013. We believe these estimates are reasonable at the present time, but we can give no assurance that changes in technology, customer usage patterns, our financial condition, the economy or other factors would not result in changes to our transmitter decommissioning plans. Any further variations from our estimates could result in a change in the expected useful lives of the underlying transmitter assets and operating results could differ in the future by any difference in depreciation expense.
	The extension of the depreciable life qualifies as a change in accounting estimate. In the fourth quarter of 2013, depreciation expense was approximately $0.1 million less than it would have been had the depreciable lives not been extended.
	Asset Retirement Obligations — Asset retirement costs are reflected in paging equipment assets with depreciation expense recognized over the estimated lives, which range between one and five years. The asset retirement costs were $3.8 million and $1.7 million at December 31, 2013 and 2012, respectively. The net increase in asset retirement cost in 2013 increased paging equipment assets which are being depreciated over the related estimated lives of 12 to 60 months.
	Depreciation, amortization and accretion for the years ended December 31, 2013 and 2012 included benefits of $1.0 million and $1.1 million, respectively, related to depreciation of these asset retirement costs. The benefits in depreciation expense for these years are due to net reductions to the asset retirement costs as a result of changes in the timing and costs of the transmitter deconstructions.
	The asset retirement costs and the corresponding liabilities that have been recorded to date generally relate to either current plans to consolidate networks or to the removal of assets at a future terminal date.
	The components of the changes in the asset retirement obligation liabilities for the periods stated were as follows:
		Short-Term				Long-Term				Total
		Portion				Portion
		(Dollars in thousands)
	Balance at January 1, 2012	$	794			$	7,557			$	8,351
	Accretion	62				676				738
	Amounts paid	(767		)		—				(767		)
	Reductions recorded	(35		)		(351		)		(386		)
	Reclassifications	325				(325		)		—
	Balance at December 31, 2012	$	379			$	7,557			$	7,936
	Accretion	(112		)		679				567
	Amounts paid	(415		)		—				(415		)
	Reductions recorded	(445		)		314				(131		)
	Reclassifications	951				(951		)		—
	Balance at December 31, 2013	$	358			$	7,599			$	7,957
	At both December 31, 2013 and 2012, accrued other liabilities included $0.4 million of asset retirement liabilities related to our efforts to reduce the number of transmitters in operation; other long-term liabilities included $7.6 million, related primarily to an estimate of the costs of deconstructing assets through the terminal date. The primary variables associated with these estimates are the number of transmitters and related equipment to be removed, the timing of removal, and a fair value estimate of the outside contractor fees to remove each asset. The fair value estimate of contractor fees to remove each asset is assumed to escalate by 4% each year through the terminal date.
	The long-term cost associated with the estimated removal costs and timing refinements due to ongoing network rationalization activities will accrete to a total liability of $9.6 million. The accretion was recorded on the interest method utilizing the following discount rates for the specified periods:
	Period	Discount Rate
	2013 – December 31 Additions(1) and Incremental Estimates	10.48	%
	2013 – January 1 through September 30 – Additions(1)	10.6	%
	2012 – December 31 Additions(1) and Incremental Estimates	10.6	%
	2012 – September 30 – Incremental Estimates(2)	12.14	%
	2012 – January 1 through September 30 – Additions(1)	10.77	%
	2011 – December 31 Additions(1) and Incremental Estimates	10.77	%
	2011 – September 30 – Incremental Estimates(2)	12.17	%
	2011 – April 1 through September 30 – Additions(1)	11.5	%
	2011 – January 1 through March 31 – Additions(1)	12.46	%
	(1)	Transmitters moved to new sites resulting in additional liability.
	(2)	Weighted average credit adjusted risk-free rate used to discount downward revision to estimated future cash flows.
	The total estimated liability is based on the transmitter locations remaining after we have consolidated the number of networks we operate and assume the underlying leases continue to be renewed to that future date. Depreciation, amortization and accretion expense for the years ended December 31, 2013, 2012 and 2011 included $0.6 million, $0.7 million and $0.8 million, respectively, for accretion expense on the asset retirement obligation liabilities.
	We believe these estimates are reasonable at the present time, but we can give no assurance that changes in technology, our financial condition, the economy or other factors would not result in higher or lower asset retirement obligations. Any variations from our estimates would generally result in a change in the assets and liabilities in equal amounts, and operating results would differ in the future by any difference in depreciation expense and accretion expense.
	Amortizable Intangible Assets and Goodwill — Other intangible assets for wireless operations consisted of a covenant to non-compete with a former executive which was amortized over a three year period. Other intangible assets for software operations were recorded at fair value on the date of acquisition and are being amortized over two to fifteen years. We recorded an impairment charge of $3.4 million to the contract-based intangible assets (non compete agreements) for our software operations for the year ended December 31, 2012 and no impairment of amortizable intangible assets was recorded for the same period in 2013 and 2011.
	The gross carrying amount of other intangible assets for the wireless operations was zero and $0.4 million, respectively, and $41.5 million for software operations at both December 31, 2013 and 2012. The gross carrying amount of the intangible assets for the wireless operations (covenant to non-compete) was fully amortized and written off in 2013. The accumulated amortization for wireless operations was $0.3 million at December 31, 2012 and $16.2 million and $11.3 million, respectively, for software operations at December 31, 2013 and 2012.
	The net consolidated balance of amortizable intangible assets consisted of the following at December 31, 2013 and 2012:
				As of December 31,
				2013										2012
		Useful Life		Gross Carrying				Accumulated				Net Balance		Gross Carrying		Accumulated			Net Balance

	Aggregate amortization expense for other intangible assets for the years ended December 31, 2013, 2012 and 2011 was $5.0 million, $6.4 million and $5.3 million, respectively.
	Estimated amortization of intangible assets for future periods was as follows:
	(Dollars in

For the year ending December 31,
2014	$	4,866
2015	3,588
2016	3,013
2017	2,880
2018	2,880
Thereafter	8,141
Total	$	25,368
Goodwill at both December 31, 2013 and 2012 was $133.0 million, which is all attributed to our software operations. Goodwill is not amortized but is evaluated for impairment at least annually, or when events or circumstances suggested a potential impairment had occurred. (See Note 1.)
We did not record any impairment of goodwill for the years ended December 31, 2013, 2012 or 2011.

	Deferred Revenue
	Deferred revenue at December 31, 2013 was $17.6 million for the current portion and $0.9 million for the non-current portion. The deferred revenue at December 31, 2012 was $27.9 million for the current portion and $0.7 million for the non-current portion. Deferred revenue primarily consisted of unearned maintenance, software license and professional services revenue. Unearned maintenance revenue represented a contractual liability to provide maintenance support over a defined period of time for which payment has generally been received. Unearned software license and professional services revenue represented a contractual liability to provide professional services more substantive than post contract support for which not all payments have been received. Customer deposits for installation represented a contractual liability to provide installation and training services for which payments have been received. At December 31, 2013 and 2012, we had received $5.4 million and $2.1 million, respectively, in customer deposits for future installation services. We will recognize revenue when the service or software is provided or otherwise meets our revenue recognition criteria.

Long-term Debt	'
	Long-term Debt
	On November 8, 2011, we executed the First Amendment to our Amended and Restated Credit Agreement (“Amended Credit Agreement”) with Wells Fargo Capital Finance, LLC (“Wells Fargo”). The Amended Credit Agreement increased the amount of the revolving credit facility to $40.0 million. The maturity date for the revolving credit facility is September 3, 2015. We may make a London Interbank Offered Rate (“LIBOR”) rate election for any amount of our debt for a period of 1, 2 or 3 months at a time; however, we may not have more than 5 individual LIBOR rate loans in effect at any given time. We may only exercise the LIBOR rate election for an amount of at least $1.0 million.
	Borrowings under this facility are secured by a lien on substantially all of our existing assets, interests in assets and proceeds owned or acquired by us.
	As of December 31, 2013, we had no outstanding debt and the Amended Credit Agreement remains in effect with approximately $40.0 million of available borrowing capacity subject to maintaining a minimum liquidity threshold of $25.0 million and to reductions for an outstanding LOC (see Note 8). The $25.0 million liquidity threshold can be satisfied by maintaining cash on hand or borrowing capacity under the Amended Credit Agreement.
	We are exposed to changes in interest rates should we have borrowings under the Amended Credit Agreement. The floating interest rate debt exposes us to interest rate risk, with the primary interest rate exposure resulting from changes in LIBOR. The definitive extent of the interest rate risk is not quantifiable or predictable because of the variability of future interest rates and business financing requirements. We do not customarily use derivative instruments to manage our interest rate risk profile.
	We are subject to certain financial covenants on a quarterly basis under the terms of the Amended Credit Agreement. These financial covenants consist of a leverage ratio and a fixed charge coverage ratio. We are in compliance with all of the required financial covenants as of December 31, 2013.
	We have also established control agreements with the financial institutions that maintain our cash and investment accounts. These agreements permit Wells Fargo to exercise control over our cash and investment accounts should we default under provisions of the Amended Credit Agreement. We are not in default under the Amended Credit Agreement and do not anticipate that Wells Fargo would need to exercise its rights under these control agreements during the term of the Amended Credit Agreement.

	On March 5, 2014, our Board of Directors declared a regular quarterly cash dividend of $0.125 per share of common stock, with a record date of March 18, 2014, and a payment date of March 28, 2014. This cash dividend of approximately $2.7 million will be paid from available cash on hand.
	Common Stock Repurchase Program — On July 31, 2008, our Board of Directors approved a program to repurchase up to $50.0 million of our common stock in the open market during the twelve-month period commencing on or about August 5, 2008. As discussed below, this program has been extended at various times, most recently through December 31, 2014 with a repurchase authority of $15.0 million as of January 1, 2014.
	Credit Suisse Securities (USA) LLC administers such purchases. We used available cash on hand and net cash provided by operating activities to fund the common stock repurchase program. This repurchase authority allows us, at management’s discretion, to selectively repurchase shares of our common stock from time to time in the open market depending upon market price and other factors.
	For the year ended December 31, 2013, we did not purchase any shares of our common stock under the repurchase program. From the inception of the program in August 2008 through December 31, 2013, we have repurchased a total of 6,268,504 shares of our common stock for approximately $59.8 million (excluding commissions).
	Repurchased shares of our common stock were accounted for as a reduction to common stock and additional paid-in-capital in the period in which the repurchase occurred. All repurchased shares of common stock are returned to the status of authorized, but unissued, shares of the Company.

Our Board of Directors approved a supplement effective March 3, 2009 which reset the repurchase authority to $25.0 million as of January 1, 2009 and extended the purchase period through December 31, 2009. On November 30, 2009, our Board of Directors approved a further extension of the purchase period from December 31, 2009 to March 31, 2010. On March 3, 2010, our Board of Directors approved a supplement to the program to repurchase our common stock in the open market effective March 3, 2010 which reset the repurchase authority to $25.0 million as of January 1, 2010 and extended the purchase period through December 31, 2010. On December 6, 2010, our Board of Directors approved another supplement effective January 3, 2011 which reset the repurchase authority to $25.0 million as of January 3, 2011 and extended the purchase period through December 31, 2011. During the first quarter of 2011, our Board of Directors temporarily suspended the program. On July 24, 2012, our Board of Directors approved an additional supplement to the common stock repurchase program effective August 1, 2012 which reset the repurchase authority to $25.0 million as of August 1, 2012 and extended the purchase period through December 31, 2013. On December 19, 2013, our Board of Directors approved a further extension of the purchase period from December 31, 2013 to December 31, 2014 and reset the repurchase authority to $15.0 million as of January 1, 2014.
(3)	The total number of shares purchased were from our President and Chief Executive Officer ("CEO") at a price of $15.21 per share in payment of required tax withholdings for common stock issued in March 2011 under the 2010 Short-Term Incentive Plan ("STIP").
(4)	The total number of shares purchased were from our CEO at a price of $14.10 per share in payment of required tax withholdings for common stock issued in March 2012 under the 2011 STIP.
(5)	On April 23, 2013, we purchased a total of 108,459 shares of common stock from our CEO and other eligible employees at a price of $12.92 per share in payment of required tax withholdings for the common stock awarded under the 2012 STIP and the 2009 LTIP.
Additional Paid-in Capital — Additional paid-in capital was $127.3 million and $125.2 million at December 31, 2013 and 2012, respectively. The increase in 2013 of $2.1 million was due primarily to the amortization of stock based compensation and a net settlement of common stock awards under the 2012 STIP and the 2009 LTIP.
Net Income per Common Share — Basic net income per common share is computed on the basis of the weighted average common shares outstanding. Diluted net income per common share is computed on the basis of the weighted average common shares outstanding plus the effect of all potentially dilutive common shares including outstanding restricted stock and RSUs, which are treated as contingently issuable shares, using the "treasury stock" method. During the second quarter of 2013, we acquired a net total of 108,459 shares of common stock after settling vested awards under the 2012 STIP and the 2009 LTIP. These shares of common stock acquired were retired and excluded from our reported outstanding share balance as of December 31, 2013. The components of basic and diluted net income per common share were as follows for the periods stated:
	For the Year Ended December 31,

USA Mobility, Inc. Equity Incentive Plan
We established the USA Mobility, Inc. Equity Incentive Award Plan (the “2004 Equity Plan”) in connection with and prior to the November 2004 merger of Arch and Metrocall. Under the 2004 Equity Plan, we had the ability to issue up to 1,878,976 shares of our common stock to eligible employees and non-executive members of the Board of Directors in the form of shares of common stock, stock options, restricted stock, RSUs or stock grants. Restricted stock granted under the 2004 Equity Plan entitled the stockholder to all rights of common stock ownership except that the restricted stock may not be sold, transferred, exchanged, or otherwise disposed of during the restriction period, which will be determined by the Compensation Committee of the Board of Directors. RSUs are generally convertible into shares of common stock pursuant to a Restricted Stock Unit Agreement when the appropriate vesting conditions have been satisfied. The fair value of each RSU is the market price of our common stock on the date of grant.
On March 23, 2012, our Board of Directors adopted the USA Mobility, Inc. 2012 Equity Incentive Award Plan (the “2012 Equity Plan”) that was subsequently approved by our stockholders on May 16, 2012. A total of 1,300,000 shares of common stock have been reserved for issuance under this plan. The 2012 Equity Plan is intended to replace the 2004 Equity Plan. As of May 16, 2012, 894,986 shares available under the 2004 Equity Plan will be available for grant under the 2012 Equity Plan. No further grants will be made under the 2004 Equity Plan. However, the 2004 Equity Plan will continue to govern all outstanding awards thereunder. As of December 31, 2013 81,957 RSUs were outstanding and subject to the provisions of the 2004 Equity Plan. Any shares which were available for grant under the 2004 Equity Plan including awards that were forfeited or lapsed unexercised as of the date of stockholders’ approval will be available for grant under the 2012 Equity Plan.
Awards under the 2012 Equity Plan may be in the form of stock options, restricted stock, RSUs, performance awards (a cash bonus award, a stock bonus award, a performance award or an incentive award that is paid in cash), dividend equivalents, stock payment awards, deferred stock, deferred stock units, or stock appreciation rights.
The following table summarizes the activities under the 2012 Equity Plan as of December 31, 2013:

2009 LTIP. On January 6, 2009, our Board of Directors approved a long-term incentive program (over a 48 month vesting period) that included a cash component and a stock component in the form of RSUs based upon achievement of expense reduction and earnings before interest, taxes, depreciation, amortization and accretion goals during our 2012 calendar year and continued employment with the Company. RSUs were granted under the 2004 Equity Plan pursuant to a Restricted Stock Unit Agreement. Our Board of Directors awarded a total of 338,834 RSUs to certain eligible employees and also approved that future cash dividends related to the existing RSUs would be set aside and paid in cash to each eligible employee when the RSUs are converted into shares of common stock. Any unvested RSUs granted under the Equity Plan and the related cash dividends were forfeited when the participant terminated employment with USA Mobility. As of December 31, 2012 a total of 80,104 RSUs had been forfeited resulting in an outstanding balance of 258,730 RSUs.
We used the fair-value based method of accounting for the 2009 LTIP and amortized $3.1 million to expense over the 48-month vesting period. A total of $0.9 million and $0.7 million was included in stock based compensation expense for the years ended December 31, 2012 and 2011, respectively, in relation to the 2009 LTIP.
Also on January 6, 2009, we provided for long-term cash performance awards to the same eligible employees under the 2009 LTIP. Similar to the RSUs, the vesting period for these long-term cash performance awards was 48 months upon attainment of the established performance goal.
We recognized $3.0 million to expense over the 48-month vesting period. A total of $0.9 million and $0.7 million was included in payroll and related expense for the years ended December 31, 2012 and 2011, respectively, for these long-term cash performance awards. Any unvested long-term cash performance awards were forfeited when the participant terminated employment with USA Mobility.
On December 31, 2012, the cash and equity awards under the 2009 LTIP vested when the pre-established performance goals were achieved. After the filing of the 2012 Annual Report on Form 10-K with the SEC, the Company converted 258,730 RSUs into shares of common stock under the 2004 Equity Plan on April 19, 2013 and paid $1.5 million in accumulated cash dividends earned on the RSUs to the eligible employees on April 26, 2013. The cash awards totaling $3.0 million under the 2009 LTIP were also paid to the eligible employees on April 26, 2013. These amounts were reflected in accounts payable and accrued liabilities and accrued compensation and benefits, respectively, as of December 31, 2012.
2011 LTIP. On March 15, 2011, our Board of Directors adopted a long-term incentive program (over a 45 month vesting period) that included a stock component in the form of RSUs. The 2011 LTIP provides eligible employees the opportunity to earn RSUs based upon achievement of performance goals established by our Board of Directors for our revenue and operating cash flows (including software operations) during the period from January 1, 2011 through December 31, 2014 (the “performance period”), and continued employment with the Company. As it relates to software operations, the performance period is considered as April 1, 2011 through December 31, 2014. Our Board of Directors approved that future cash dividends related to the existing RSUs will be set aside and paid in cash to each eligible employee when the RSUs are converted into shares of common stock. Existing RSUs would be converted into shares of common stock on the earlier of a change in control of the Company (as defined in the 2004 Equity Plan for RSUs granted before May 16, 2012 or the 2012 Equity Plan for grants on or after May 16, 2012) or on or after the third business day following the day that we file our 2014 Annual Report on Form 10-K (“2014 Annual Report”) with the SEC but in no event later than December 31, 2015. Any unvested RSUs awarded under the 2011 LTIP and the related cash dividends are forfeited if the participant terminates employment with USA Mobility.
On April 7, 2011, our Board of Directors granted 211,587 RSUs to eligible employees in our software operations under the 2004 Equity Plan pursuant to a Restricted Stock Agreement. The grant date fair value was $3.0 million (net of estimated forfeitures) based upon the closing price per share of our common stock of $15.68. In 2012, our Board of Directors awarded 122,673 RSUs to eligible employees with a grant date fair value of $1.3 million (net of estimated forfeitures). During 2012, 101,294 RSUs and the related cash dividends were forfeited with a related fair value of $1.4 million. The outstanding RSUs under the 2011 LTIP as of December 31, 2012 were 232,966 RSUs.
On December 27, 2012, our Board of Directors approved a modification to the 2011 LTIP performance goals for revenue and operating cash flows during the performance period as the original award was not expected to vest. This modification affected 18 eligible employees in the software operations. As a result of reversing previously recognized compensation expense and recording compensation for the modified award, the Company recognized a benefit to stock based compensation expense of $0.2 million. We used the fair-value based method of accounting for the 2011 LTIP and are amortizing the remaining $1.6 million of the grant date fair value (net of estimated forfeitures) over the remaining vesting period.
In 2013, our Board of Directors awarded 42,092 RSUs to eligible employees in the software operations under the 2011 LTIP with a grant date fair value of $0.5 million (net of estimated forfeitures). During 2013, 48,061 RSUs and the related cash dividends were forfeited with a related fair value of $0.5 million. As of December 31, 2013 there were 226,997 RSUs outstanding for the software operations.
A total of $0.8 million, $0.1 million and $0.6 million was included in stock based compensation expense for the years ended December 31, 2013, 2012 and 2011, respectively, in relation to the 2011 LTIP for our software operations. In addition to the benefit for the modification of $0.2 million, stock based compensation expense for the year ended December 31, 2012 included a net benefit of $0.4 million for forfeitures under the 2011 LTIP associated with the departure of two former executives in our software operations.
On January 22, 2013 (the grant date), our Board of Directors awarded 253,739 RSUs to eligible employees in the wireless operations under the 2011 LTIP. The Board of Directors granted these RSUs under the 2012 Equity Plan pursuant to a Restricted Stock Unit Agreement. The grant date fair value of the RSUs was $2.7 million (net of estimated forfeitures). During 2013, an additional 138,980 RSUs were awarded by our Board of Directors to an eligible employee with a grant date fair value of $2.0 million (net of estimated forfeitures). During 2013, 2,689 RSUs and the related cash dividends were forfeited with a related fair value of $26,000. As of December 31, 2013 there were 390,030 RSUs outstanding for the wireless operations. A total of $2.0 million was included in stock based compensation expense for the year ended December 31, 2013 in relation to the 2011 LTIP for our wireless operations.
On December 13, 2013, our Board of Directors approved a modification to the 2011 LTIP performance goals for operating cash flows during the performance period. The original award was expected to vest, therefore, the modification had no impact on the grant date fair value. This modification affected 37 and 14 eligible employees in the software operations and wireless operations, respectively.

Board of Directors Compensation. On August 1, 2007, for periods of service beginning on July 1, 2007, our Board of Directors approved that, in lieu of RSUs, each non-executive director will be granted in arrears on the first business day following the quarter of service, restricted stock under the 2004 Equity Plan or the 2012 Equity Plan for their service on the Board of Directors and committees thereof. The restricted stock will be granted quarterly based upon the closing price per share of our common stock at the end of each quarter, such that each non-executive director will receive $40,000 per year of restricted stock ($50,000 for the Chair of the Audit Committee). The restricted stock will vest on the earlier of a change in control of the Company (as defined in the 2004 Equity Plan for restricted stock granted before May 16, 2012 or the 2012 Equity Plan for grants on or after May 16, 2012) or one year from the date of grant, provided, in each case, that the non-executive director maintains continuous service on the Board of Directors. Future cash dividends related to the restricted stock will be set aside and paid in cash to each non-executive director on the date the restricted stock vests. In addition to the quarterly restricted stock grants, the non-executive directors will be entitled to cash compensation of $40,000 per year ($50,000 for the Chair of the Audit Committee), also payable quarterly. These sums are payable, at the election of the non-executive director, in the form of cash, shares of common stock, or any combination thereof.
On July 23, 2013, for the period of service beginning on July 1, 2013, our Board of Directors approved a change in the non-executive directors’ compensation plan. The non-executive directors will receive restricted stock quarterly based upon the closing price per share of our common stock at the end of each quarter, such that each non-executive director will receive $60,000 per year of restricted stock ($70,000 for the Chair of the Audit Committee). The restricted stock will vest on the earlier of a change in control of the Company (as defined in the 2012 Equity Plan) or one year from the date of grant, provided, in each case, that the non-executive director maintains continuous service on the Board of Directors. Future cash dividends related to the restricted stock will be set aside and paid in cash to each non-executive director on the date the restricted stock vests. The non-executive directors are required to hold shares of common stock and/or restricted stock equal to three times their annual cash compensation ($135,000 for each non-executive director and $165,000 for the Chair of the Audit Committee) as measured on June 30th of each year. Should the value of the non-executive director’s holdings fall below the established minimum, the non-executive director will be deemed in compliance with the requirement provided that the non-executive director retained shares equal to the total number of restricted stock granted during the preceding three years. All non-executive directors will have a three year grace period to reach this ownership threshold. In addition to the quarterly restricted stock grants, the non-executive directors will be entitled to cash compensation of $45,000 per year ($55,000 for the Chair of the Audit Committee), also payable quarterly. These sums are payable, at the election of the non-executive director, in the form of cash, shares of common stock, or any combination thereof.

(1)	The quarterly restricted stock awarded is based on the price per share of our common stock on the last trading day prior to the quarterly award date.
(2)	Amount includes forfeitures of 3,189 restricted stock resulting from a director's voluntary resignation from the Board.
(3)	Amount excludes interest earned and paid upon vesting of shares of restricted stock.
The shares of restricted stock will vest one year from the date of grant and the related cash dividends on the vested restricted stock will be paid to our non-executive directors at vesting. Grants of shares of restricted stock made after May 16, 2012 will reduce the number of shares eligible for future issuance under the 2012 Equity Plan.
We use the fair-value based method of accounting for the equity awards. A total of $0.2 million was included in stock based compensation expense for each of the years ended December 31, 2013, 2012 and 2011 in relation to the restricted stock granted to our non-executive directors.
Board of Directors Common Stock. No directors have elected common stock in lieu of cash payments for their services during the years ended December 31, 2013, 2012 and 2011.
The following table reflects the stock based compensation expense for the awards under the Equity Plans:

Total stock based compensation	$	3,045			$	1,224			$	1,530
The 2009 LTIP vested on December 31, 2012, as such, no stock based compensation expense was incurred in 2013. The 2011 LTIP was awarded to the eligible employees in the wireless operations effective for January 1, 2013, which resulted in an increase in stock based compensation expense in 2013. Stock based compensation expense for the year ended December 31, 2012 in software operations reflects the net benefit of $0.6 million due to forfeitures under the 2011 LTIP and the modification to the performance goals under the 2011 LTIP.

	Current State Income Tax Provision — The current state income tax expense for 2013 decreased from the 2012 state income tax expense by $0.2 million. This is due primarily to the decline in taxable income.
	Net Operating Losses — As of December 31, 2013, we had approximately $343.8 million of Federal net operating losses (“NOLs”) available to offset future taxable income. The Internal Revenue Code (“IRC”) Section 382 (“IRC Section 382”) limited NOLs as of December 31, 2013 totaled $50.4 million which may be used at a rate of $6.1 million per year. The remainder of our Federal NOLs carryforwards of $293.4 million is not subject to a limitation. The IRC Section 382 limited NOLs will fully expire on December 31, 2021, and the unlimited NOLs begin expiring in 2023 and will fully expire in 2029. We have foreign NOLs available for future years of approximately $0.7 million which do not expire and foreign tax credits of $0.5 million.
	Valuation Allowance — We assess the recoverability of our deferred income tax assets, which represent the tax benefits of future tax deductions, by considering the adequacy of future taxable income from all sources. This assessment is required to determine whether based on all available evidence, it is “more likely than not” (which means a probability of greater than 50%) that all or some portion of the deferred income tax assets will be realized in future periods. The deferred income tax asset valuation allowance balances at December 31, 2013 and 2012 were $119.3 million and $118.7 million, respectively. (Included in this amount were approximately $0.9 million and $0.7 million for foreign operations at December 31, 2013 and 2012, respectively.) The valuation allowance reduces the deferred income tax assets to their estimated recoverable amounts which at December 31, 2013 and 2012 represented 19.5% and 27.6%, respectively, of the available deferred income tax assets. The decrease in the percentage of recoverable deferred income tax assets in 2013 reflects the increase in the valuation allowance relating to deferred income tax assets from Alternative Minimum Tax ("AMT") credit carryforwards and updated estimates of our expected benefits from such assets based on the forecasted results for the wireless and software operations. During 2013 we did not make any adjustment to our valuation allowance account except for the increase of $0.6 million due to the AMT tax credit carryforward.
We consider both positive and negative evidence when evaluating the recoverability of our deferred income tax assets. During the fourth quarter of each year, we prepare a multi-year forecast of taxable income for our wireless and software operations. The wireless operations have experienced a continuing decline in revenue and taxable income as subscribers switch to other communication solutions. The software operations have been impacted by the economic slowdown of the past several years resulting in customers deferring or delaying purchases. The wireless and software operations forecast of taxable income are not sufficient to result in the full realization of our deferred income tax assets.
The anticipated effective income tax rate is expected to continue to differ from the Federal statutory rate of 35% primarily due to the effect of state income taxes, the effect of changes to the deferred income tax asset valuation allowance, permanent differences between book and taxable income and certain discrete items. The earnings of non-US subsidiaries are deemed to be indefinitely reinvested in non-US operations.
As of December 31, 2013 and 2012, there were no uncertain income tax positions and as such, no liability for unrecognized tax benefits.
Income Tax Audits — Our Federal income tax returns have been examined by the IRS through December 31, 2008. The audits of the Federal returns for the years ended 2005 through 2008 resulted in no changes. The IRS also audited Amcom’s 2009 Federal tax return (pre-acquisition) with no changes. The 2010, 2011 and 2012 income tax returns of the Company have not been audited by the IRS and are within the statute of limitations (“SOL”).
We operate in all states and the District of Columbia and are subject to various state income and franchise tax audits. The states’ SOL varies from three to four years from the later of the due date of the return or the date filed. We usually file our Federal and all state and local income tax returns on or before September 15 of the following year; therefore, the SOLs for those states with a three year SOL is open for calendar years ending 2010 through 2013, and for the four year SOL states, the SOL is open for years ending from 2009 through 2013.

Commitments and Contingencies Disclosure [Abstract]	'
Commitments and Contingencies	'
	Commitments and Contingencies
	Contractual Obligations — We incurred significant commitments and contractual obligations as of December 31, 2013 as outlined below.
	In April 2008, we amended an existing contract with a vendor for invoice processing services over a three-year contract term. This contract automatically renewed annually, thereafter. We have a remaining contractual obligation of $0.1 million, including both fixed and variable components based on units in service.
	In November 2009, we entered into an agreement with a vendor for our headquarters office space in Springfield, Virginia. The office lease commenced in April 2010. The total rent expense is estimated to be approximately $1.4 million, which includes $0.4 million for lease incentives for a five-year lease term. We have a remaining commitment of $0.4 million as of December 31, 2013.
	In October 2010, we entered into an agreement with a vendor for certain satellite services over a three-year contract term. In March 2012, we signed an amendment to cover additional satellite services. In December 2012, we further amended the agreement with additional services, term and conditions. We have a remaining commitment of $0.9 million, as of December 31, 2013.
	In October 2010, we amended an existing contract with another vendor for satellite service with an annual renewal. The annual cost is $0.5 million.
	In June 2011, we amended an existing contract with a vendor for office space in Plano, Texas. The amendment commenced in October 2011. The total rent expense is estimated to be approximately $2.5 million, which includes $0.2 million for rent abatements for a five-year lease term. We have a remaining commitment of $1.6 million as of December 31, 2013.
	In December 2011 and effective for February 2012, we contracted with a provider for network maintenance services over a three-year contract term. The contract includes a fixed per site cost based on the number of transmitters, which can be adjusted with a 90 day notice. We have a minimum commitment with this vendor of $0.1 million.
	In May 2012, we contracted with a managed service-hosting provider for certain computer support services over a three-year contract term. We have a remaining contractually obligation of $0.2 million.
	In September 2012, we signed a contract with a vendor for telecommunication services with a two-year term. We have a remaining contractual obligation of $0.1 million.
	Our software operations have agreements and commitments with vendors for office space in Minnesota, New York, New Hampshire, Florida and Australia. The remaining commitments for the office leases are as follows: Minnesota of $1.5 million through February 2019; New Hampshire of $0.8 million through June 2017; Florida of $0.1 million through June 2016; and Australia of $0.4 million through July 2016.
	As of December 31, 2013, our commitment for the office space in New York is $0.1 million through April 2014. On August 27, 2013, we entered into an agreement with a vendor for new office space in New York, New York for a ten-year lease term. The office rent started in the first quarter of 2014 upon commencement of the tenant's build out. The total rent expense is estimated to be approximately $3.6 million, which includes $0.4 million for lease incentives.
	Other Commitments — We also have various LOCs outstanding with multiple state agencies. The LOCs typically have one to three-year contract requirements and contain automatic renewal terms. The deposits of $0.1 million related to the LOCs are included within other assets on the consolidated balance sheets.
	During the third quarter of 2012, we established a $0.2 million LOC for an international sale. During the third quarter of 2013, we established a $0.1 million LOC associated with a new facility lease for software operations. These LOCs have reduced our available borrowing capacity under our Amended Credit Agreement.
	Legal Contingencies — We are involved, from time to time, in lawsuits arising in the normal course of business. We believe these pending lawsuits will not have a material adverse impact on our financial results or statement of income.
	Operating Leases — We have operating leases for office and transmitter locations. Substantially all of these leases have lease terms ranging from one month to five years. We continue to review our office and transmitter locations, and intend to replace, reduce or consolidate leases, where possible.
	Future minimum lease payments under non-cancelable operating leases at December 31, 2013 were as follows:
	For the Year Ended December 31,	(Dollars in
		thousands)
	2014	$	6,948
	2015	4,957
	2016	3,795
	2017	2,160
	2018	1,520
	Thereafter	3,609
	Total	$	22,989
	These leases typically include renewal options and escalation clauses. Where material, we recognize rent expense on a straight-line basis over the lease period. The difference between rent paid and rent expense is recorded as accrued other and other long-term liabilities on the consolidated balance sheets.
	Total rent expense under operating leases for the years ended December 31, 2013, 2012 and 2011, was approximately $19.1 million, $20.4 million and $26.1 million, respectively.
	Indemnification — We and certain of our subsidiaries, as permitted under Delaware law, have entered into indemnification agreements with several persons, including each of our present directors and certain members of management, for defined events or occurrences while the director or member of management is, or was serving, at our request in such capacity. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have a director and officer insurance policy that limits our exposure and enables us to recover a portion of any future amounts paid under the terms of the policy. As a result of our insurance policy coverage, we believe the estimated fair value of these indemnification agreements is immaterial. Therefore, we have not recorded a liability for these agreements as of December 31, 2013 and 2012, respectively.
	Our services and product sales agreements typically include certain provisions that indemnify customers from claims of intellectual property infringement made by third parties arising from the use of our products. To date, we have not incurred and have not accrued for any costs related to such indemnification provisions.

	Employee Benefit Plans
	USA Mobility, Inc. Savings and Retirement Plan — The USA Mobility, Inc. Savings and Retirement Plan (the “Plan”), is open to all USA Mobility employees working a minimum of twenty hours per week with at least 30 days of service. The Plan qualifies under Section 401(k) of the IRC. Under the Plan, participating employees may elect to voluntarily contribute a percentage of their qualifying compensation on a pretax or after-tax basis up to the annual maximum amounts established by the IRC. The Company matches 50% of the employee’s contribution, up to 5% of each participant’s gross salary per pay period, or 50% of the employee’s annualized contribution up to $2,500, whichever is greater. There is a per-pay-period match on the 5% component and an end-of-year true up on the $2,500 component. Contributions made by the Company become fully vested three years from the date of the participant’s employment (33% in year one, 66% in year two and 100% in year three). For purposes of vesting, a year consists of 1,000 hours or more. Other than the Company match as discussed above, profit sharing contributions are discretionary. Effective January 1, 2012, the Amcom Software, Inc. 401(k) Plan was merged into the Plan, and all qualified Amcom employees are eligible to participate in the Plan as noted above. Matching contributions under the Plan were approximately $1.1 million for both wireless and software operations for the years ended December 31, 2013 and 2012 and $0.6 million for the year ended December 31, 2011 for wireless operations. From March 3, 2011 through December 31, 2011, software operations’ employees were covered under the Amcom Software, Inc. 401(k) Plan and the matching contribution during this period was $0.3 million.
	USA Mobility, Inc. Severance Pay Plan — The USA Mobility, Inc. Severance Pay Plan for salaried employees, hourly employees and commissioned direct-sales employees (the “Severance Plan”) provides severance payments on a discretionary basis to certain employees who are terminated involuntarily under certain specified circumstances as defined in the Severance Plan. The amount of the benefit to be provided is based on the employee’s compensation and years of service with USA Mobility as defined. Eligible terminated employees will receive two weeks of compensation for each completed year of service, up to a maximum of twenty-six weeks of compensation with a minimum compensation of two weeks. We maintain a substantially similar type of severance pay plan for executive employees at and above the level of vice-president. At December 31, 2013 and 2012, the accrued severance and restructuring liability included $1.5 million and $2.6 million, respectively, associated with these plans, reflecting our expected headcount reductions (see Note 14).

	Segment Reporting
	With the acquisition of Amcom on March 3, 2011, we currently have two reportable operating segments: a Wireless segment and a Software segment. These segments are operated and managed as strategic business units and are organized by products and services. We measure and evaluate our segments based on segment operating income, consistent with the chief operating decision maker's assessment of segment performance.
	Our segments and their principal activities consist of the following:
	Wireless		Provides local, regional and nationwide one-way paging and advanced two-way messaging services
			and mobile voice and data services through third party providers.
	Software		Provides mission critical unified communications solutions for contact centers, emergency management, mobile event notification and messaging.
	Effective January 1, 2014 Amcom Software, Inc was merged into USA Mobility Wireless, Inc. The Company has and is undertaking the consolidation of wireless and software operation activities and functions.
	We use a non-GAAP financial measure as a key element in determining performance for purposes of incentive compensation under our annual STIP. That non-GAAP financial measure is operating cash flow (“OCF”) defined as earnings before interest, taxes, depreciation, amortization, accretion and impairment (“EBITDA”) less purchases of property and equipment (EBITDA is defined as operating income plus depreciation, amortization, accretion and impairment, each determined in accordance with GAAP). Purchases of property and equipment are also determined in accordance with GAAP.

Accounting Policies [Abstract]	'
Business	'
	Business — USA Mobility, Inc. and its subsidiaries (collectively, “USA Mobility” or the “Company”), through its indirect wholly owned subsidiary, USA Mobility Wireless, Inc. (“wireless operations”) is a leading provider of wireless messaging, mobile voice and data and unified communications solutions in the United States. We provide one-way and two-way messaging services. One-way messaging consists of numeric and alphanumeric messaging services. Numeric messaging services enable subscribers to receive messages that are composed entirely of numbers, such as a phone number, while alphanumeric messages may include numbers and letters which enable subscribers to receive text messages. Two-way messaging services enable subscribers to send and receive messages to and from other wireless messaging devices, including pagers, personal digital assistants and personal computers. We also offer voice mail, personalized greeting, message storage and retrieval and equipment loss and/or maintenance protection to both one-way and two-way messaging subscribers. These services are commonly referred to as wireless messaging and information services.
	In addition, the Company, through its indirect wholly owned subsidiary, Amcom Software, Inc. (“Amcom” or “software operations”), provides mission critical unified communications solutions for contact centers, emergency management, mobile event notification and Smartphone messaging. The combined product offering is capable of addressing a customer’s mission critical communication needs. Amcom delivers software solutions, which enable seamless critical communications. Amcom’s unified communications suite (includes solutions for contact centers, emergency management, mobile event notification, and messaging) connects people across a changing complement of communication devices.
Organization and Principles of Consolidation	'
	Organization and Principles of Consolidation — We are a holding company formed to effect the merger of Arch Wireless, Inc. and subsidiaries (“Arch”) and Metrocall Holdings, Inc. and subsidiaries (“Metrocall”), which occurred on November 16, 2004. Prior to the merger, we had conducted no operations other than those incidental to our formation. On March 3, 2011, we acquired Amcom.
	The accompanying consolidated financial statements include our accounts and the accounts of our wholly owned direct and indirect subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. We have an investment in a Canadian company that is 10% owned and is accounted for under the cost method of accounting.
Preparation of Financial Statements	'
	Preparation of Financial Statements — Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Amounts shown on the consolidated statements of income within the operating expense categories of cost of revenue; service, rental and maintenance; selling and marketing; and general and administrative are recorded exclusive of severance and restructuring, depreciation, amortization and accretion and impairment. These items are shown separately on the consolidated statements of income within operating expenses. Foreign currency translation adjustments were immaterial and were not presented separately in our consolidated statements of stockholders’ equity and balance sheets, and consequently no statements of comprehensive income are presented.
	All adjustments are of a normal recurring nature except for adjustments related to the acquisitions. The statements of income and the estimated fair value of the assets acquired and liabilities assumed have been included in our consolidated financial statements from the dates of the acquisitions.
Use of Estimates	'
	Use of Estimates — The preparation of these consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. On an on-going basis, we evaluate estimates and assumptions, including but not limited to those related to the impairment of long-lived assets, intangible assets subject to amortization and goodwill, accounts receivable allowances, revenue recognition, depreciation expense, asset retirement obligations, severance and restructuring and income taxes. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
Impairment of Long-Lived Assets, Intangible Assets Subject to Amortization and Goodwill	'
	Impairment of Long-Lived Assets, Intangible Assets Subject to Amortization and Goodwill — We are required to evaluate the carrying value of our long-lived assets, amortizable intangible assets and goodwill. Amortizable intangible assets include customer related intangibles, technology based intangibles, contract based intangibles and marketing intangibles that primarily resulted from our acquisition of Amcom in 2011 and IMCO in 2012. Such intangibles are amortized over periods ranging from two to fifteen years. We assess whether circumstances exist which suggest that the carrying value of long-lived assets may not be recoverable. When applicable, we assess the recoverability of the carrying value of our long-lived assets and certain amortizable intangible assets based on estimated undiscounted cash flows to be generated from such assets. In assessing the recoverability of these assets, we forecast estimated enterprise-level cash flows based on various operating assumptions such as revenue forecasted by product line and in-process research and development cost. If the forecast of undiscounted cash flows does not exceed the carrying value of the long-lived assets, we would record an impairment charge to the extent the carrying value exceeded the fair value of such assets.
	Goodwill resulting from our acquisitions is not amortized but is evaluated for impairment at least annually, or when events or circumstances suggest a potential impairment has occurred. We have selected the fourth quarter to perform this annual impairment test. We will evaluate goodwill for impairment between annual tests if indicators of impairment exist. GAAP requires the comparison of the fair value of the reporting unit to the carrying amount to determine if there is potential impairment. For this determination, all of our goodwill has been assigned to our software operations, which is also deemed to be the reporting unit. The first step of the impairment test involves comparing the fair values of the reporting unit with its carrying values. If the reporting unit’s fair value is less than the carrying amount of the reporting unit, we perform the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill. The amount, by which the implied fair value is less than the carrying value of the goodwill, if any, is recognized as an impairment loss. The fair value of the reporting unit is estimated using a discounted cash flow methodology. This analysis requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, estimation of the useful life over which cash flows will occur, and determination of our weighted average cost of capital. We also consider the market value of our invested capital as a confirmatory measurement of fair value.
Accounts Receivable Allowances	'
	Accounts Receivable Allowances — Our two most significant allowance accounts are: an allowance for doubtful accounts and an allowance for service credits. Provisions for these allowances are recorded on a monthly basis and are included as a component of general and administrative expenses and a reduction of revenue, respectively.
	Estimates are used in determining the allowance for doubtful accounts and are based on historical collection experience and current and forecasted trends. In determining these percentages, we review historical write-offs, including comparisons of write-offs to provisions for doubtful accounts and as a percentage of revenues. We compare the ratio of the allowance to gross receivables to historical levels, and monitor amounts collected and related statistics. The allowance for doubtful accounts for both our wireless operations and software operations was $1.3 million and $1.2 million (of which $0.7 million and $0.6 million related to software operations) at both December 31, 2013 and 2012, respectively. We write off receivables when they are deem uncollectible. While write-offs of customer accounts have historically been within our expectations and the provisions established, we cannot guarantee that future write-off experience will be consistent with historical experience, which could result in material differences in the allowance for doubtful accounts and related provisions.
	The allowance for service credits and related provisions for wireless operations is based on historical credit percentages, current credit and aging trends and actual credit experience. We analyze our past credit experience over several time frames. Using this analysis along with current operational data including existing experience of credits issued and the time frames in which credits are issued, we establish an appropriate allowance for service credits. The allowance for service credits for wireless operations were $0.3 million and $0.4 million at December 31, 2013 and 2012, respectively. While credits issued have been within our expectations and the provisions established, we cannot guarantee that future credit experience will be consistent with historical experience, which could result in material differences in the allowance for service credits and related provisions.
	Other allowance accounts for wireless operations totaled $0.4 million at both December 31, 2013 and 2012, respectively. The primary component of these allowance accounts reduces accounts receivable for lost and non-returned pagers to the expected realizable amounts. We base this allowance on historical payment trends. The other allowance for software operations totaled $0.2 million and $0.1 million at December 31, 2013 and 2012, respectively. This allowance reduces maintenance revenue based on historical actual payment trends and aging trends experience.
Revenue Recognition	'
	Revenue Recognition — We recognize revenue when four basic criteria have been met: (1) persuasive evidence of an arrangement exists, (2) delivery has occurred or services rendered, (3) the fee is fixed or determinable and (4) collectability is reasonably assured. Amounts billed to customers but not meeting these revenue recognition criteria are deferred until all four criteria have been met.
	Our wireless operations’ revenue consists primarily of service rental and maintenance fees charged to customers on a monthly, quarterly, or annual basis. Revenue also includes the sale of messaging devices directly to customers and other companies that resell our services. With respect to revenue recognition for multiple deliverables, we evaluated these revenue arrangements and determined that two separate units of accounting exist, paging service revenue and product sales. We recognize paging service revenue over the period the service is performed; revenue from product sales is recognized at the time of shipment or installation. We have a variety of billing arrangements with our customers resulting in deferred revenue from advance billings and accounts receivables for billing in-arrears arrangements.
	For our software operations, we enter into contractual arrangements that include a fee that is fixed or determinable. This contractual arrangement has been agreed to by the customer and we review customer creditworthiness to assure collectability.
	Our software operations’ revenue consists primarily of the sale of software (license fees), professional services (primarily installation and training), equipment (to be used in conjunction with the software) and maintenance support (post-contract support). The software is licensed to end users under an industry standard software license agreement. Our software products are considered to be “off-the-shelf software” as the software is marketed as a stock item that customers can use without customization.
	For purposes of disclosure, revenue from the software operations consists of two primary components: (1) operations revenue consisting of software license revenue, professional services revenue and equipment sales, and (2) maintenance revenue.
	We generally sell software licenses, professional services, equipment and maintenance in multiple-element arrangements. At inception of the arrangement, we allocate the arrangement consideration to the software deliverables (software licenses, professional services and maintenance) as a group and to the non-software deliverables (equipment and maintenance on equipment, when applicable) using the relative selling price method. When performing this allocation, the estimated selling price for each deliverable is based on vendor specific objective evidence of fair value (“VSOE”), third party evidence of fair value (“TPE”), or if VSOE and TPE are not available, the best estimated selling price (“BESP”) for selling the element on a stand-alone basis. We have determined that TPE is not a practical alternative due to differences in our service offerings compared to other parties and the availability of relevant third-party pricing information. The amount of revenue allocated to delivered items is limited by contingent revenue, if any.
	Post contract support is allocated using VSOE as an input in the relative selling price allocation. For software licenses, professional services and equipment we have determined that neither VSOE nor TPE is available and as such, we have used BESP as an input in order to allocate our arrangement fees. We determine BESP by considering our overall pricing objectives and market conditions. Significant pricing practices take into consideration our discounting practices, the size and volume of our transactions, the customer demographic, the geographic area where our services are sold, our price lists, our go-to-market strategy, historical standalone sales and contract prices. The determination of BESP is made through consultation with and approval by management, taking into consideration the go-to-market strategy. As our go-to-market strategies evolve, we may modify our pricing practices in the future, which could result in changes in relative selling prices, including both VSOE and BESP.
	In multiple-element arrangements, the arrangement consideration allocated to our non-software deliverables (equipment) is generally recognized upon delivery to the customer.
	For our software deliverables, which include software licenses, professional services, and post contract support, we further allocate arrangement consideration using the residual method. As noted above, we have not established VSOE for our software licenses and professional services. However, we have established, and continue to maintain, VSOE for post contract support. As such, the residual amount relating to the revenue from software licenses and professional services is recognized as revenue over the period of delivery to the customer, if known, or when fully delivered to the customer. Maintenance revenue is deferred and recognized over the maintenance period, generally one year.
Long-Lived Assets	'
	Long-Lived Assets — Leased messaging devices sold or otherwise retired were removed from the accounts at their net book value using the weighted-average method. Property and equipment are reported at cost. Property and equipment is depreciated using the straight-line method over the following estimated useful lives:
		Estimated Useful
		Life
	Asset Classification	(In Years)
	Buildings	20
	Leasehold improvements	3 or lease term
	Messaging devices	2-Jan
	Paging and computer equipment	5-Jan
	Furniture and fixtures	5-Mar
	Vehicles	3
	We calculate depreciation on certain of our paging equipment assets using the group life method; accordingly, ordinary asset retirements and disposals are charged against accumulated depreciation with no gain or loss recognized.
Asset Retirement Obligations	'
	Asset Retirement Obligations — We recognized liabilities and corresponding assets for future obligations associated with the retirement of assets. We have paging equipment assets, principally transmitters, which are located on leased locations. The underlying leases generally require the removal of equipment at the end of the lease term; therefore, a future obligation exists (see Note 3).
Severance and Restructuring	'
	Severance and Restructuring — We continually evaluate our staffing levels to meet our business objectives for both the wireless and software operations and our strategy to reduce cost in our wireless operations in line with the declining revenue and subscriber base. Severance costs are reviewed periodically to determine whether a severance charge is required due to employers’ accounting for post-employment benefits. We are required to accrue post-employment benefits if certain specified criteria are met. Post-employment benefits include salary continuation, severance benefits and continuation of health insurance benefits.
	From time to time, we will announce reorganization plans that may include eliminating positions. Each plan is reviewed to determine whether a restructuring charge is required to be recorded related to costs associated with exit or disposal activities. We are required to record an estimate of the fair value of any termination costs based on certain facts, circumstances and assumptions, including specific provisions included in the underlying reorganization plan.
	Also from time to time, we cease to use certain facilities, such as office buildings and transmitter locations, including available capacity under certain agreements, prior to expiration of the underlying contractual agreements. Exit costs based on certain facts, circumstances and assumptions, including remaining minimum lease payments, potential sublease income and specific provisions included in the underlying contract or lease agreements are reviewed in each of these circumstances on a case-by-case basis to determine whether a restructuring charge is required to be recorded.
	Subsequent to recording such accrued severance and restructuring liabilities, changes in market or other conditions may result in changes to assumptions upon which the original liabilities were recorded that could result in an adjustment to the liabilities and, depending on the circumstances, such adjustment could be material (see Note 14).
Income Taxes	'
	Income Taxes — We file a consolidated U.S. Federal income tax return and income tax returns in state, local and foreign jurisdictions (principally Canada and Australia) as required. The provision for current income taxes is calculated and accrued on income and expenses expected to be included in current year U.S. and foreign income tax returns. The provision for current income taxes may also include interest, penalties and an estimated amount reflecting uncertain tax positions.
	Deferred income tax assets and liabilities are computed based on temporary differences between the financial statement values and the tax basis of assets and liabilities including net operating loss and tax credit carryforwards at the enacted tax rates expected to apply to taxable income when taxes are actually paid or recovered. Changes in deferred income tax assets and liabilities are included as a component of deferred income tax expense. Deferred income tax assets represent amounts available to reduce future income taxes payable. We provide a valuation allowance when we consider it “more likely than not” (greater than a 50% probability) that a deferred income tax asset will not be fully recovered. Adjustments to the valuation allowance are a component of the deferred income tax expense.
	Assets and liabilities are established for uncertain tax positions taken or positions expected to be taken in income tax returns when such positions fail to meet the “more likely than not” threshold based on the technical merits of the positions. Estimated interest and penalties related to uncertain tax positions are included as a component of income tax expense. We assess whether previously unrecognized tax benefits may be recognized when the tax position is (1) more likely than not of being sustained based on its technical merits, (2) effectively settled through examination, negotiation or litigation, or (3) settled through actual expiration of the relevant tax statutes. At December 31, 2013 and 2012, there were no uncertain tax positions.
Research and Product Development	'
	Research and Product Development — Development costs incurred in the research and development of new software products and enhancements to existing software products for external use are expensed as incurred until technological feasibility has been established. Costs incurred after technological feasibility is established and before the product is ready for general release would be capitalized. Costs eligible for capitalization were not material to the consolidated financial statements and were expensed as incurred to service, rental and maintenance expense.
Shipping and Handling Costs	'
	Shipping and Handling Costs — We incur shipping and handling costs to send and receive messaging devices to/from our wireless operations’ customers and shipping costs related to equipment sales in our software operations. These costs are expensed as incurred and included in general and administrative expenses for wireless operations and costs of revenue for software operations.
Advertising Expenses	'
	Advertising Expenses — Advertising costs are charged to operations when incurred because they occur in the same period as the benefit is derived. These costs are included in selling and marketing expenses. We do not incur any direct response advertising costs.
Stock Based Compensation	'
	Stock Based Compensation — Compensation expense associated with common stock, restricted stock units (“RSUs”) and shares of restricted common stock (“restricted stock”) is recognized over the instruments’ vesting period based on the fair value of the related instruments.
Cash Equivalents	'
	Cash Equivalents — Cash equivalents include short-term, interest-bearing instruments purchased with initial or remaining maturities of three months or less.
Sales and Use Taxes	'
	Sales and Use Taxes — Sales and use taxes imposed on the ultimate consumer are excluded from revenue where we are required by law or regulation to act as collection agent for the taxing jurisdiction.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments — Our financial instruments include our cash, letters of credit (“LOCs”), accounts receivable and accounts payable. The fair value of cash, accounts receivable and accounts payable are equal to their carrying values at December 31, 2013 and 2012.
Earnings Per Common Share	'
	Earnings Per Common Share — The calculation of earnings per common share is based on the weighted-average number of common shares outstanding during the applicable period. The calculation for diluted earnings per common share recognizes the effect of all potential dilutive common shares that were outstanding during the respective periods, unless the impact would be anti-dilutive (see Note 6).
Recent and New Accounting Pronouncements	'
	Recent and New Accounting Pronouncements — Accounting pronouncements issued or effective during the year ended December 31, 2013 are not applicable to us or are not anticipated to have a material effect on our financial position or statement of income.
