NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Summary of Significant Accounting Policies

Description of Business and Capital Structure

tw telecom inc. (together with its wholly-owned subsidiaries, the “Company”) is a leading national provider of managed network services, specializing in business Ethernet, data networking, converged, Internet Protocol ("IP") based virtual private network or "IP VPN", Internet access, voice, including voice over Internet Protocol or “VoIP”, and network security services to enterprise organizations, including public sector entities, and carriers throughout the United States, including their global locations.

The Company has one class of common stock outstanding with one vote per share. The Company also is authorized to issue shares of preferred stock. The Company’s Board of Directors has the authority to establish voting powers, preferences and special rights for the preferred stock. No shares of preferred stock have been issued.

Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. These condensed consolidated financial statements should therefore be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013 filed with the SEC. The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include all adjustments of a normal, recurring nature that are, in the opinion of management, necessary to present fairly the financial position and results of operations for the interim periods presented. The results of operations for an interim period are not necessarily indicative of the results of operations for a full fiscal year.

Prior Year Reclassifications

Beginning January 1, 2014, the Company is reporting revenue from taxes and fees in a separate line item on the condensed consolidated statements of operations and is reporting revenue from dedicated high capacity Ethernet services in data and Internet services rather than network services. These reclassifications have been made in the prior year condensed consolidated statement of operations to conform to the current year presentation. Neither of these changes affects total revenue for the current period or prior periods. The following table provides revenue as currently reported and previously reported for the three months ended March 31, 2013:

	Three months ended March 31, 2013
	As Currently Reported		As Previously Reported
	(amounts in thousands)
Revenue:
Data and Internet services	$	211,721	$	202,082

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Accumulated Other Comprehensive Income

The balance in accumulated other comprehensive income as of March 31, 2014 and December 31, 2013 relates to the Company's investments that are classified as available-for-sale securities. The Company recognized no material changes in accumulated other comprehensive income for the three months ended March 31,2014 or 2013. There were no significant items reclassified out of accumulated other comprehensive income for the three months ended March 31,2014 or 2013.

Revenue

The Company’s revenue is derived primarily from business communications services comprised of the following:

• Data and Internet services include services that enable customers to connect their internal computer networks between locations and to access external networks, including Internet access and data transport at high speeds using Ethernet protocol, local and wide-area business Ethernet and IP VPN solutions, including service enhancements that provide customers with more visibility and control over their Ethernet services, which we refer to as the "Intelligent Network". Data and Internet services also include a portfolio of managed services including the data and Internet components of converged services, which fully integrates a combination of certain communication applications including IP VPN, Internet, enterprise Session Initiation Protocol ("SIP") trunking (a VoIP solution), security and managed router service into a single managed IP solution; and the data and Internet components of integrated services, which enable customers to purchase a full array of access options that include Internet services.

• Voice services are traditional voice capabilities, whether provided over Time Division Multiplexing ("TDM") or VoIP, including those provided as standalone and bundled services, long distance and toll free services. Voice services also include the voice components of managed and integrated services.

• Network services are point-to-point services that transmit voice, data and images using state-of-the-art fiber optics, and collocation services that provide secure space with controlled climate and power where customers can locate their equipment to connect to the Company’s network in facilities equipped for enterprise information technology environmental requirements.

The Company also generates revenue from intercarrier compensation, which is comprised of switched access services and reciprocal compensation. Switched access represents the compensation from another carrier for the delivery of traffic from a long distance carrier’s point of presence to an end-user’s premises provided through the Company’s switching facilities. The Federal Communications Commission ("FCC") and state public utility commissions regulate switched access rates in their respective jurisdictions. Reciprocal compensation represents compensation from local exchange carriers (“LECs”) for local exchange traffic originated on another LEC’s facilities and terminated on the Company’s facilities.

The Company classifies certain taxes and fees billed to customers and remitted to government authorities on a gross versus net basis in revenue and expense. In making this determination, the Company assesses, among other things, whether the Company is the primary obligor or principal taxpayer for the taxes and fees assessed in each jurisdiction where the Company does business. In jurisdictions where the Company determines that it is the principal taxpayer, the Company records the taxes and fees on a gross basis, including the taxes and fees in revenue and expense. In jurisdictions where the Company determines that it is merely a collection agent for the government authority, the Company records the taxes on a net basis. The total amount of such taxes and fees classified as revenue is included in "Taxes and fees" on the Company's condensed consolidated statements of operations.

The Company’s customers include enterprise organizations in a wide variety of industry segments including, among others, the financial services, technology and scientific, health care, distribution, manufacturing and professional services industries, data centers, cloud application providers, public sector entities, system integrators and communications service providers, including incumbent local exchange carriers ("ILECs"), competitive local exchange carriers ("CLECs"), wireless communications companies and cable companies.

tw telecom inc.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

Revenue for network, data and Internet, and the majority of voice services is generally billed in advance on a monthly fixed rate basis and recognized over the period the services are provided. Revenue for the majority of intercarrier compensation and certain components of voice services, such as long distance, is generally billed on a transactional basis in arrears based on a customer’s actual usage; therefore, estimates are used to recognize revenue in the period earned.

The Company evaluates whether receivables are reasonably assured of collection based on certain factors, including the likelihood of billing being disputed by customers. If there is a billing dispute with a customer, revenue generally is not recognized until the dispute is resolved. The Company does not recognize revenue associated with contract termination charges until cash is received.

Significant Customers

The Company has substantial business relationships with a few large customers, including major telecommunications carriers. The Company’s 10 largest customers accounted for an aggregate of 17% of the Company’s total revenue for both the three months ended March 31,2014 and 2013. No customer accounted for 5% or more of total revenue for the three months ended March 31,2014 or 2013.

2. Earnings per Common Share and Potential Common Share

Basic earnings per common share (“EPS”) is measured as the income allocated to common stockholders divided by the weighted average outstanding common shares for the period. Diluted EPS is similar to basic EPS but presents the dilutive effect on a per share basis of potential common shares (such as convertible securities and stock options) as if they had been converted to shares at the beginning of the period presented. Potential common shares that have an anti-dilutive effect (e.g., those that increase income per share) are excluded from diluted EPS.

The following is a reconciliation of the numerators and denominators used in the basic and diluted EPS computations:

	Three Months Ended March 31,
	2014			2013
	(amounts in thousands, except per share amounts)
Numerator
Net income	$	9,791		$	13,144
Allocation of net income to unvested restricted stock	(179		)	(255		)
Net income allocated to common stockholders, basic	$	9,612		$	12,889
Net income allocated to common stockholders, diluted	$	9,612		$	12,889
Denominator
Basic weighted average shares outstanding	138,088			149,129
Dilutive potential common shares:
Stock options	384			1,432
Unvested restricted stock	1,625			1,891
Diluted weighted average shares outstanding	140,097			152,452
Basic earnings per share	$	0.07		$	0.09
Diluted earnings per share	$	0.07		$	0.09

There were no anti-dilutive shares for the three months ended March 31, 2014. Shares of common stock subject to issuance upon conversion of the Company’s 2³/₈% Convertible Senior Debentures due 2026 (the “Convertible Debentures”) and restricted stock awards and restricted stock units to be settled in common stock upon vesting, which were excluded from the computation of diluted weighted average shares outstanding because their inclusion would be anti-dilutive, totaled 21.0 million shares for the three months ended March 31,2013.

At March 31, 2014 and December 31, 2013, the carrying values of investments included in cash and cash equivalents approximated fair value. The aggregate fair value of available-for-sale securities by major security type is included in Note 5. The amortized cost basis of the available-for-sale securities was not materially different from the aggregate fair value. The contractual maturities of the Company’s available-for-sale securities are all within one year.

Proceeds from the sale and maturity of available-for-sale securities were $69.5 million and $34.0 million during the three months ended March 31,2014 and 2013, respectively. Gains and losses on investments are calculated using the specific identification method and are recognized during the period the investment is sold. The Company recognized no material unrealized or realized net gains or losses during the three months ended March 31,2014 and 2013.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

March 31, 2014, the Company recognized debt extinguishment costs of $1.3 million, comprised of $0.9 million for premiums associated with the redemption and $0.4 million for write-offs of unamortized deferred debt issuance costs and issuance discount related to the 2018 Notes.

Covenant Compliance

As of March 31, 2014, tw telecom inc. and its wholly-owned subsidiary, Holdings, were in compliance with all of their debt covenants.

5. Fair Value Measurements

Fair value, as defined by relevant accounting standards, is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would complete a transaction and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions and risk of nonperformance.

Fair Value Hierarchy

Relevant accounting standards set forth a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Relevant accounting standards establish three levels of inputs that may be used to measure fair value:

• Level 1—Quoted prices in active markets for identical assets or liabilities. Level 1 assets that are measured at fair value on a recurring basis consist of the Company’s investments in U.S. Treasury money market mutual funds that are traded in an active market with sufficient volume and frequency of transactions, and are included as a component of cash and cash equivalents in the condensed consolidated balance sheets.

• Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets that are measured at fair value on a recurring basis consist of the Company’s investments in commercial paper and debt securities issued by the U.S. Treasury and other U.S. government agencies using observable inputs in less active markets and are included as a component of cash and cash equivalents and investments in the condensed consolidated balance sheets. Level 2 liabilities that are measured, but not carried, at fair value on a recurring basis include the Company’s long-term debt. The Company’s long-term debt has not been listed on any securities exchange or quoted on an inter-dealer automated quotation system. The Company has estimated the fair value of its long-term debt based on indicative pricing published by certain investment banks or trading levels in its long-term debt.

• Level 3—Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities. The Company did not have any Level 3 assets or liabilities that were measured at fair value at March 31, 2014 and December 31, 2013.

6. Stock-Based Compensation

During the three months ended March 31,2014, the Company granted restricted stock awards and restricted stock units with respect to 1.4 million shares and no stock options. As of March 31, 2014, the Company had 3.7 million restricted stock awards and restricted stock units that were unvested and 0.5 million stock options outstanding, of which 0.5 million were exercisable.

tw telecom inc.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

As of March 31, 2014, there was $86.4 million of total unrecognized compensation expense related to unvested restricted stock awards and restricted stock units, which is expected to be recognized over a weighted-average period of 2.7 years, and no unrecognized compensation expense related to unvested stock options.

7. Commitments and Contingencies

Management routinely reviews the Company’s exposure to liabilities incurred in the normal course of its business operations. Where a probable contingency exists and the amount of the loss can be reasonably estimated, the Company records the estimated liability. Considerable judgment is required in analyzing and recording such liabilities and actual results may vary from the estimates.

The Company’s pending legal proceedings are limited to litigation incidental to its business. In the opinion of management, the ultimate resolution of these matters will not have a material adverse effect on the Company’s financial statements.

8. Supplemental Guarantor Information

The $480 million principal amount 5³/₈% Senior Notes due 2022 (the "2022 Notes"), $450 million principal amount 5³/₈% Senior Notes due 2022 (the "2022 Mirror Notes") and $350 million principal amount 6³/₈% Senior Notes due 2023 (the "2023 Notes") (collectively, the "Senior Notes") are unsecured obligations of Holdings ("Issuer") and are fully and unconditionally guaranteed by the Company (“Parent Guarantor”) and substantially all of the Issuer’s subsidiaries (“Combined Subsidiary Guarantors”). The guarantees are joint and several. The Combined Subsidiary Guarantors are directly or indirectly wholly owned by the Issuer, which is wholly owned by the Parent Guarantor. A significant amount of the Issuer’s cash flow is generated by the Combined Subsidiary Guarantors. As a result, funds necessary to meet the Issuer’s debt service obligations are provided in large part by distributions or advances from the Combined Subsidiary Guarantors. The Senior Notes are governed by indentures that contain certain restrictive covenants. These restrictions affect, and in many respects limit or prohibit, among other things, the ability of the Parent Guarantor, the Issuer and its subsidiaries to incur indebtedness, make prepayments of certain indebtedness, pay dividends, make investments, engage in transactions with stockholders and affiliates, issue capital stock of subsidiaries, create liens, sell assets and engage in mergers and consolidations.

The following information sets forth the Company’s Condensed Consolidating Balance Sheets as of March 31, 2014 and December 31, 2013, Condensed Consolidating Statements of Operations for the three months ended March 31,2014 and 2013, Condensed Consolidating Statements of Comprehensive Income for the three months ended March 31,2014 and 2013, and Condensed Consolidating Statements of Cash Flows for the three months ended March 31,2014 and 2013.

Overview

We are a leading national provider of managed network services, specializing in business Ethernet, data networking, converged, IP VPN, Internet access, voice, including VoIP, and network security services to enterprise organizations, including public sector entities, and carriers throughout the U.S., including their global locations. Our revenue is derived from business communication services, including data, high-speed Internet access, network and voice services. Our customers include enterprise organizations in a wide variety of industry segments including, among others, the financial services, technology and scientific, health care, distribution, manufacturing and professional services industries, data centers, cloud application providers, public sector entities, system integrators and communications service providers, including ILECs, CLECs, wireless communications companies and cable companies.

Through our subsidiaries, we serve 76 metropolitan markets with local fiber networks that are connected to our regional fiber facilities and national IP backbone. As of March 31, 2014, our fiber network spanned nearly 33,000 route miles (the majority of which were metropolitan route miles) connecting to 20,778 buildings served directly by our metropolitan fiber facilities. Included in the total buildings served directly by our local fiber facilities are approximately 500 third party data centers across the country where customers deploy their own equipment or connect to cloud application providers. We are able to extend our reach beyond our fiber networks by providing off-network solutions to customers within and outside our 76 markets. We continue to extend our fiber footprint within our existing markets by connecting our network into additional locations and to expand our data, voice and IP networking capabilities between our markets, supporting secure end-to-end business Ethernet, IP VPN and converged solutions for customers.

Although we analyze revenue by customer type, we present our financial results as one segment across the U.S. because our business is centrally managed.

Strategic Market Expansion

In November 2013, we announced a strategic market expansion to increase our addressable market by significantly expanding our metropolitan fiber route miles, including entry into five new markets and accelerating the density of our metropolitan fiber footprint in 28 existing markets. Subsequent to our announcement that our strategic market expansion would comprise expanding our fiber network in 27 existing markets, we agreed to accept additional fiber in one additional existing market, Kansas City. This additional fiber did not increase our total expected capital expenditures for 2014 (see "Liquidity & Capital Resources-- Capital Expenditures and Requirements.") The new markets that we still plan to enter in 2014 are Boston, Philadelphia, Cleveland and Richmond. In April 2014, we commenced sales in our new Salt Lake City market. As part of this expansion, we are also increasing our regional fiber footprint for greater capacity, increased network control and more cost effective connectivity. To facilitate this expansion, we entered into long-term capital leases for fiber that we plan to light with our own electronics. The initial term of the leases is 20 years, with two ten-year renewals at our option, and automatic annual renewals thereafter until termination by either party. We plan to complete integration of our expanded fiber with our networks and systems by the end of 2014, and to activate new routes throughout 2014 in our new and existing markets for sales of services to our customers. Year-to-date through May 7, 2014, we have completed integration and activation of our expansion fiber in 11 expansion markets.

Revenue Trends

Total Revenue

Our revenue has grown sequentially for the past 38 consecutive quarters through March 31, 2014, including throughout various economic cycles. Our annual year-over-year revenue growth rate increased for each of the years ended December 31, 2010, 2011 and 2012 and was 5.1%, 7.4% and 7.6%, respectively. These higher year-over-year revenue growth rates were primarily due to increased demand, low revenue churn and an increase in certain taxes and fees that are reported on a gross versus net basis in revenue and expense. We also believe that our new and enhanced services, our customer experience initiatives to increase customer loyalty and retention and improved economic conditions contributed to our growing revenue during these periods.

In 2012, we began to experience lower year-over-year quarterly revenue growth rates compared to the same periods in the prior year and continued to experience a lower year-over-year quarterly revenue growth rate in the three months ended December 31, 2013. Our 2013 annual revenue growth rate of 6.4% was lower than the prior year. In 2013, we commenced several growth initiatives designed to increase our revenue growth rate by focusing on increased sales to capture growing market demand and share. In the second half of 2013, we achieved higher growth in our sales, or "bookings" (i.e., signed contracts), and service installations year over year, which we believe was the result of our growth initiatives. During the three months ended March 31, 2014, our sales and service installations continued to grow at a higher rate year-over-year, and our year-over-year revenue growth rate was 7.1%, compared to 6.2% for the same period in 2013. Accordingly, we expect our 2014 annual revenue growth rate to be higher than our 2013 annual revenue growth rate, although we may experience fluctuations in our quarterly revenue growth rates.

Due to the time required to obtain or build necessary facilities, obtain rights to install equipment in multi-tenant buildings and other factors related to service installation, some of which are not within our control, there is often a lag between the time that a sale is made, and the time revenue commences. Our installation intervals are generally longer for the more complex solutions delivered to our customers. In some situations, the timing of service installations may be subject to factors that our customers control, such as their readiness for us to install equipment on their premises or the readiness of their equipment. Due to all of these factors, installation intervals may range between two weeks for single-site, less complex services to 6 to 12 months or longer for the more complex solutions.

24

tw telecom inc.

We believe that increasing our rate of revenue growth will depend on increasing sales and service installations to keep pace with the growing total base of recurring revenue, retaining revenue from existing customers and a stronger economy. We expect our future revenue growth to be driven in part by greater demand for our data and Internet services due to the increasingly web-based economy that includes IT strategies such as cloud computing, collaboration, data center connectivity and disaster recovery, all of which require the reliable connectivity and network capacity that we provide. We also expect that our advanced service capabilities and expanded national footprint will drive more demand for our existing Ethernet, managed and Internet service suites, enhance our future data and Internet services revenue growth and enable us to serve more customers with multi-point, multi-city locations.

Revenue Reclassification

Beginning January 1, 2014, we are reporting revenue from taxes and fees in a separate line item on our condensed consolidated statements of operations in order to provide better visibility into the impact of changes in those items. Accordingly, certain revenue from taxes and fees that was previously reported by line of business is now classified as taxes and fees. Certain revenue from taxes and fees reported by customer type elsewhere in this report has been classified as taxes and fees as well. In addition, we are reporting revenue from dedicated high capacity Ethernet services in data and Internet services rather than network services for better alignment of our service categories, which does not impact revenue by customer type. These reclassifications have been made in the prior year condensed consolidated statements of operations to conform to the current year presentation. Neither of these changes affects total revenue for the current period or prior periods.

Enterprise Customer Revenue

Revenue from enterprise customers has increased sequentially for the past 47 consecutive quarters through March 31, 2014 and increased 9.2% for the three months ended March 31, 2014 as compared to 8.4% for the same period in 2013, primarily due to increased installations of our data and Internet services such as business Ethernet, managed and Internet services. Revenue from our enterprise customers represented 76% of our total revenue in the three months ended March 31, 2014. We expect our future revenue growth to come primarily from enterprise customers, including our current customer base, largely due to our advanced network capabilities, growth initiatives, including the expansion of our sales and sales support personnel and services portfolio, and strategic market expansion.

Carrier Customer Revenue

Our carrier revenue represented 17% of our total revenue in the three months ended March 31, 2014 compared to 18% of our total revenue in the same period last year. Carrier revenue has been declining as a percentage of revenue due to the higher contribution from enterprise customer revenue coupled with continued disconnections and repricing of carrier contracts upon renewals somewhat offset by higher installed sales of Ethernet services to carriers to serve their end users’ needs as they transition from network services to Ethernet-based technologies. Carrier revenue from wireless providers represented 27% and 30% of total carrier revenue for the three months ended March 31, 2014 and 2013, respectively. We expect that our expanded service offerings to our wholesale customers will continue to contribute to carrier revenue; however, our carrier revenue historically has been impacted by pricing declines in connection with carrier customer contract renewals, disconnections resulting from price competition from other carriers, network grooming and carrier consolidation that inhibits the growth rate of carrier revenue. We expect these impacts on our carrier revenue to continue and to fluctuate from quarter to quarter.

Taxes and Fees

We classify certain taxes and fees billed to customers and remitted to government authorities on a gross versus net basis in revenue and expense. Taxes and fees represented 6% and 5% of our total revenue in the three months ended March 31, 2014 and 2013, respectively. We expect that revenue from taxes and fees will fluctuate based on changes in rates and growth or declines in revenue subject to these taxes and fees.

Intercarrier Compensation Revenue

Intercarrier compensation revenue, consisting of switched access services and reciprocal compensation, represented 1% of our total revenue for the three months ended March 31, 2014, and is expected to decline in the future due to federal and state mandated rate reductions for terminating traffic and changes in the regulatory regime for intercarrier compensation. Under a 2011 FCC order, intercarrier compensation rates are declining over a six-year period that began in 2012 with rate decreases occurring in July of each year through 2017. We expect, as a result of the FCC order, a reduction of approximately $4.0 million in intercarrier compensation revenue in the year ended December 31, 2014 compared to 2013 that may be somewhat offset by growth in minutes of use. Approximately one-fourth of this reduction has already occurred through the three months ended March 31, 2014. In addition, we expect that intercarrier compensation revenue will fluctuate based on variations from period to period in minutes of use originating and terminating on our network and fluctuations in carrier settlements.

Revenue and Customer Churn

Revenue churn, defined as the average lost recurring monthly billing for the period from a customer’s partial or complete disconnection of services (excluding pricing declines upon contract renewals and lost usage revenue) compared to reported revenue, is a measure used by management to evaluate revenue retention. Customer and service disconnections occur as part of the normal course of business and are primarily associated with price competition from other providers, customers moving facilities to other locations and network grooming, business contractions, financial difficulties and consolidation, among other reasons. Revenue churn was 0.8% of monthly revenue in the three months ended March 31, 2014 and 0.9% in each of the years ended December 31, 2011, 2012 and 2013, reflecting improvement from the last recessionary period of late 2007 through 2009. We believe that this improvement in revenue churn is a result of improved economic conditions as well as our expanded service portfolio, measures we implemented to increase revenue retention and our customer experience initiatives. As a component of revenue churn, revenue lost from customers fully disconnecting services was 0.2% for the years ended December 31, 2011, 2012 and 2013 and for the three months ended March 31, 2014. We continue our initiatives to maintain revenue churn that is low relative to our industry, but do not expect contribution to our revenue growth rate from a lower revenue churn rate. If our revenue churn were to increase, our revenue growth would likely be negatively impacted. If we experience another adverse economic cycle, we could experience higher revenue churn that would likely negatively impact our revenue growth. We cannot predict the total impact on revenue from future customer disconnections or the timing of such disconnections or whether these favorable churn trends will continue.

Customer churn, defined as the average monthly customer turnover for the period compared to the average monthly customer count for the period, was 0.8% for the three months ended March 31, 2014, compared with 1.0%, 1.0% and 0.9% for the years ended December 31, 2011, 2012 and 2013, respectively. The majority of this churn came from our smaller customers, which we expect will continue.

Pricing

We experience significant price competition from the ILECs, CLECs and cable companies across our service categories that impacts our revenue. We also believe that technology advancements over the years in the telecommunications industry have resulted in lower unit costs for some electronics and equipment that drives customer demand for higher bandwidth at the same or lower prices.

Service agreements in our industry typically range from two to five years, with fixed pricing for the contract term. When contracts are renewed with no changes to the services, pricing is frequently reduced to current market levels as a renewal incentive. The impact of those price reductions on our revenue may fluctuate from quarter to quarter. In addition, during the terms of agreements, customers may purchase additional services or increase or decrease the bandwidth of existing services, subject to applicable early termination charges, depending on their business needs. In some cases, the impact of re-pricing is mitigated by customers' purchase of additional bandwidth or services.

Expenses and Modified EBITDA Trends

Pricing of Special Access Services

We purchase a substantial amount of special access services primarily from ILECs, including services based on the two major technologies available in the industry, Ethernet and TDM, to expand the reach of our network and also provide special access services to customers over our fiber facilities in competition with ILECs. The ILECs have argued before the FCC that the high capacity telecommunications services that they sell, including interstate special access services we buy from them, should no longer be subject to regulations governing price and quality of service. We have advocated that the FCC modify certain of its interstate special access pricing flexibility rules to return these services to price-cap regulation to protect against unreasonable price increases for carriers like us and for regulation of ILEC service quality.

The FCC is reviewing its regulation of special access pricing in a pending proceeding commenced in 2005 that has not yet resulted in proposed rules. In 2012, the FCC suspended the operation of the pricing flexibility triggers, which means that certain ILECs cannot qualify for pricing flexibility in additional geographic areas, pending further FCC review. If the special access services we buy from the ILECs were to be further deregulated, ILECs would have a greater ability to continue to increase the price and reduce the service quality of special access services they sell to us, but we may eventually experience less pricing pressure on the special access service we sell due to higher competitive pricing. As the prices we must pay for special access services increase, our margins may be pressured. If ILEC price reductions were to occur, we would likely experience downward pressure on the prices we charge our customers for special access services and reductions in the prices we pay ILECs for special access services that we purchase. We cannot predict when the FCC will conclude the proceeding on interstate special access pricing regulation or the impact of any such action.

26

tw telecom inc.

In addition, the FCC has granted ILEC requests for forbearance from regulation of certain Ethernet and OC-n high capacity services offered by the ILECs as special access, with the result that prices we would pay for those services are no longer price regulated and can increase. We and other carriers are seeking to reverse these forbearance requests. In the meantime, we have secured commercial agreements with the larger ILECs, and continue to pursue agreements with other providers, for those services.

In October 2013, AT&T gave notice of its intent to effectively increase its pricing for TDM special access circuits by eliminating five and seven year tariffed term and volume plans that previously provided more favorable pricing than the three year plans that would still be available. We and certain other carriers impacted by this pricing increase opposed this increase through advocacy efforts with the FCC. The proposed tariff change was withdrawn in early 2014, but a similar change could be proposed again that could have an adverse impact on our special access costs.

We have expanded our reach by implementing commercial arrangements and connections with the ILECs, other competitive carriers and cable companies for the provision of Ethernet services to deliver certain of our advanced services to end users in areas not directly served by our fiber networks. We also have commercial arrangements with carriers to provide access to our customers' locations in areas outside of our 76 markets. With growing demand for multi-location customer solutions, both within and outside our markets, we are provisioning services to more off-network locations resulting in higher access costs.

Modified EBITDA Trends and Growth Initiatives

We regularly implement various initiatives designed to expand our revenue growth, Modified EBITDA margin (see Note 3 to the table under “Three Months Ended March 31, 2014 Compared to Three Months Ended March 31, 2013--Operating Income and Net Income” for a definition of Modified EBITDA margin) and cash flow that require both capital and operating investments, which can temporarily impact our Modified EBITDA margin until growth in revenue absorbs the increased costs. We believe that these initiatives resulted in growth of our revenue, Modified EBITDA margin and cash flows during the three years ended December 31, 2012.

Modified EBITDA (see Note 2 to the table under “Three Months Ended March 31, 2014 Compared to Three Months Ended March 31, 2013--Operating Income and Net Income” for a definition of Modified EBITDA and reconciliations of Modified EBITDA to net income, which is the most comparable GAAP measure for operating performance, and Modified EBITDA to net cash provided by operations, which is the most comparable GAAP measure for liquidity) grew 7.4%, 8.6% and 2.2% in the years ended December 31, 2011, 2012 and 2013, respectively, each compared to the prior year, and grew 0.6% in the three months ended March 31,2014 compared to the same period last year. Modified EBITDA margin was 36.4%, 36.8% and 35.3% for the years ended December 31, 2011, 2012 and 2013, respectively. These margins reflected the absorption of increased costs for network access due to higher prices and greater off-network reach, and costs associated with growth initiatives designed to increase the rate of revenue growth, including further expansion of our sales and sales support staff, and IT and technical personnel. These margins were also impacted by the dilutive effect of certain taxes and fees that are reported on a gross versus net basis in revenue and expense (see “Revenue” in Note 1 to the condensed consolidated financial statements). Modified EBITDA margin was 33.5% in the three months ended March 31, 2014 compared to 35.7% in the same period in the prior year. The decline was the result of costs associated with our growth initiatives and increases in commissions, certain taxes and fees and network access costs. Costs associated with growth initiatives had a greater impact on Modified EBITDA margin for the three months ended March 31, 2014 and the year ended December 31, 2013 than in the same periods in 2012 and 2011.

In 2013 our growth initiatives required both capital and operating investments and we continue to make these investments in 2014, including hiring additional sales, sales support and other operational personnel to support our strategic market expansion. For 2014, our investment plans for our growth initiatives and strategic market expansion include an expected increase in sales personnel headcount of approximately 7%, which represents a lower incremental increase in sales personnel than our incremental increase in such personnel for the year ended December 31, 2013. Our capital investments in 2013 and 2014 in support of our growth initiatives include new service development, further automation and equipment to integrate and connect the strategic market expansion into our national network and operating infrastructure.

We expect the continued investments and expense associated with our growth initiatives and strategic market expansion (see "Strategic Market Expansion" above) will continue to pressure our Modified EBITDA margin and cash flow in the near term until we can achieve consistently higher service installations and an acceleration of our rate of revenue growth sufficient to absorb these higher costs. We expect our Modified EBITDA margin to remain at levels similar to that reported for the three months ended March 31, 2014 and then to begin expanding toward the end of 2014 as a result of anticipated higher revenue growth, as discussed above in "Revenue Trends-- Total Revenue." While these initiatives and market expansion are designed to increase sales in the longer term to accelerate our future revenue growth rate, we cannot assure that these and other initiatives

27

tw telecom inc.

will be sufficient to achieve our objectives of increased revenue growth, margins and cash flow or the timing of such anticipated benefits.

We believe that future margin expansion will come from higher service installations, further leveraging our on-network facilities and increasing the network density of our less mature markets, since historically we have generally experienced margin improvement and increased cash flow from our less dense markets as those markets are expanded through on-net building additions and other network expansions. We believe that our strategic market expansions within our existing markets provide an opportunity to accelerate the increase of network density in many of these existing markets which, if successful, we expect to lead to margin improvement and stronger cash flow generation over time.

The expected reductions in intercarrier compensation revenue discussed above under "Revenue Trends" are also expected to pressure our margins because of the relatively high margins associated with that revenue. Our revenue and margins may also be impacted by, among other risks, economic fluctuations, competitive pressures, higher special access costs including from growth in multi-location customer solutions driven by demand, fuel and energy costs, fluctuations in certain taxes and fees and any future inflationary pressures.

Seasonality and Fluctuations

We continue to expect business fluctuations to impact sequential quarterly trends in revenue, margins and cash flow. This includes the timing, as well as any seasonality, of sales and service installations, usage, rate changes, disputes, settlements, repricing for contract renewals and fluctuations in revenue churn, especially from carrier customers, expenses, capital expenditures and certain taxes and fees. Historically, our expense in the first quarter has been impacted by the resetting of payroll taxes in the new year. Our past experience with quarterly fluctuations may not necessarily be indicative of future results.

Because we generally do not recognize revenue subject to billing disputes until the dispute is resolved, the timing of dispute resolutions and settlements may positively or negatively affect our revenue in a particular quarter. The timing of disconnections may also impact our results in a particular quarter, with disconnections early in the quarter generally having a greater impact. The timing of capital and other expenditures may affect our margins or cash flow. The convergence of any of these or other factors such as fluctuations in usage, increases or decreases in certain taxes and fees or pricing declines upon contract renewals in a particular quarter may result in our revenue growing more or less than previous trends, may impact our margins and other financial results.

___________________

⁽¹⁾  We classify certain taxes and fees billed to customers and remitted to government authorities on a gross versus net basis in revenue and expense. This has no impact on net income or Modified EBITDA but is dilutive to Modified EBITDA margin.

The primary driver of total revenue growth was increased data and Internet services revenue from installed services to enterprise customers. The increase in data and Internet services revenue primarily resulted from installations of strategic Ethernet and VPN-based services and other services to enterprise customers, partially offset by revenue churn and re-pricing of renewed customer contracts at lower rates. Strategic services, which includes Ethernet and IP VPN services, comprised 52.9% of data and Internet services revenue for the three months ended March 31,2014 compared to 52.0% for the three months ended March 31,2013, representing 17.2% period-over-period growth in revenue from these services.

Voice services revenue increased primarily as a result of installations of converged and other voice services and an increase in usage based services, partially offset by revenue churn. Revenue based on the minutes of service used by customers included in voice services was 3% of our total revenue for both the three months ended March 31,2014 and 2013.

Network services revenue decreased primarily due to the impact of revenue churn and re-pricing of renewed customer contracts at lower rates, largely from carrier customers.

Revenue from taxes and fees increased primarily due to growth in revenue to which these charges apply.

Intercarrier compensation revenue decreased primarily as a result of the impact of an FCC-mandated rate reduction in July 2013 as well as lower favorable settlements in the current period as compared to the same period in the prior year.

Total costs and expenses	$	363,327		$	329,039		$	34,288		10.4	%
(1)  Includes the following non-cash stock-based employee compensation expense:
Operating	$	539		$	583		$	(44	)	(7.5	)%
Selling, general and administrative	$	8,847		$	8,879		$	(32	)	(0.4	)%

Operating Expenses. Our operating expenses consist of costs directly related to the operation and maintenance of our network and the provisioning of our services. These costs, which are net of capitalized labor and overhead costs on capital projects, include the salaries and related expenses of customer care, provisioning, network maintenance, technical field and network operations and engineering personnel, costs to repair and maintain our network, and costs paid to other carriers for access to their facilities, interconnection, and facilities leased and associated utilities. We carry a significant portion of our traffic on our own fiber infrastructure, enhancing our ability to minimize and control costs to purchase network services from other carriers, or access costs. The increase in operating expenses primarily related to higher network access costs as a result of revenue growth and growth in demand for multi-location customer solutions, both within and outside our markets, an increase in certain taxes and fees and higher employee-related costs to support ongoing revenue growth and our growth initiatives.

Selling, General and Administrative Expenses. Selling, general and administrative expenses consist of salaries and related costs for employees and other expenses related to sales and marketing, bad debt, IT, billing, regulatory, administrative and legal functions. The increase in these expenses primarily related to higher employee-related costs resulting from expansion of our sales and sales support personnel to support our growth initiatives and commissions resulting from higher installations of service.

Depreciation, Amortization and Accretion Expense. The increase in depreciation, amortization and accretion expense was attributable to property, plant and equipment additions during 2014 and 2013, net of the impact of fully depreciated assets.

⁽¹⁾  See Note 1 under "Revenue" above.

⁽²⁾  “Modified EBITDA” is a non-GAAP financial measure and is defined by us as net income (loss) before depreciation, amortization and accretion expense, interest expense, interest income, debt extinguishment costs, other income (loss), impairment charges, income tax expense (benefit), cumulative effect of change in accounting principle, and non-cash stock-based employee compensation expense. Not all of the aforementioned items occur in each reporting period, but have been included in the definition based on historical activity. Modified EBITDA is not intended to replace operating income (loss), net income (loss), cash flow and other measures of financial performance and liquidity reported in accordance with accounting principles generally accepted in the United States. Rather, Modified EBITDA is a measure of operating performance and liquidity that investors may consider in addition to such measures. Our management believes that Modified EBITDA is a standard measure of operating performance and liquidity that is commonly reported and widely used by analysts, investors, and other interested parties in the telecommunications industry because it eliminates many differences in financial, capitalization, and tax structures, as well as non-cash and non-operating charges to earnings. We believe that Modified EBITDA trends are a valuable indicator of whether our operations are able to produce sufficient operating cash flow to fund working capital needs, service debt obligations and fund capital expenditures. We currently use Modified EBITDA for these purposes. Modified EBITDA also is used internally by our management to assess ongoing operations and is a measure used to test compliance with certain covenants of our senior notes, our Revolver and our Term Loan. The definition of EBITDA under our Revolver, our Term Loan and our senior notes differs, but not materially, from the definition of Modified EBITDA used in this table. Modified EBITDA as used in this document may not be comparable to similarly titled measures reported by other companies due to differences in accounting and disclosure policies. The reconciliation between Modified EBITDA and net income (loss), which is the most comparable GAAP measure for operating performance, is as follows (amounts in thousands):

Modified EBITDA	$	136,808		$	136,027

⁽³⁾  Modified EBITDA margin represents Modified EBITDA as a percentage of revenue.

Interest Expense. The decrease in interest expense was largely related to the discount on the Convertible Debentures becoming fully accreted at the end of the first quarter of 2013, the retirement of the Convertible Debentures, the retirement of the 2018 Notes and the impact of the rate decrease on the Term Loan in connection with the refinancing of the Term Loan in April 2013, somewhat offset by interest attributable to the 2022 Mirror Notes and 2023 Notes issued in August 2013, as well as capital leases.

Debt Extinguishment Costs. Debt extinguishment costs for the three months ended March 31, 2014 resulted from the redemption of the remaining 2018 Notes and consisted of cash paid for redemption premiums of $0.9 million and non-cash write-offs of unamortized deferred debt issuance costs and issuance discount of $0.4 million.

Income before Income Taxes. The decrease in income before income taxes resulted primarily from higher depreciation, amortization and accretion expense, partially offset by lower interest expense as discussed above.

Income Tax Expense. The decrease in income tax expense primarily resulted from lower income before income taxes.

Net Income and Modified EBITDA. The decrease in net income resulted from a decrease in income before income taxes, partially offset by lower income tax expense, as discussed above. Modified EBITDA was largely unchanged as revenue growth was largely offset by costs associated with an increase in personnel primarily to support our growth initiatives and higher commissions resulting from increased installations of service. The decline in Modified EBITDA margin in the three months ended March 31, 2014 compared to the same period in the prior year is attributable to costs associated with our growth initiatives, increased commissions, certain taxes and fees and network access costs. For the three months ended March 31, 2014 and 2013, Modified EBITDA, together with cash, cash equivalents and investments, has been sufficient to cover our capital expenditures and service our debt. We expect to generate sufficient Modified EBITDA in the foreseeable future to cover our expected capital expenditures and debt service requirements together with cash on hand and borrowing capacity under our existing Revolver.

Liquidity and Capital Resources

Historically, we have generated cash flow from operations consisting primarily of payments received from customers for the provision of our services offset by payments to other telecommunications carriers, payments to employees, and payments for interest and other operating, selling, general and administrative expenses. We have also generated cash from debt and equity financing activities and have used these funds and cash flows from operations to service or repay our debt obligations, make capital expenditures to expand our network, repurchase our common stock and fund acquisitions.

In September 2013, we completed a tender offer for $406.5 million aggregate principal amount of the 2018 Notes. On March 1, 2014, we redeemed all of the remaining $23.5 million principal amount of 2018 Notes at a redemption price of 104% of the principal amount. The redemption resulted in a total use of cash for the three months ended March 31, 2014 of $24.4 million, which included $0.9 million of redemption premiums. Additionally, we used $104.2 million of cash during the three months ended March 31, 2014 to repurchase our common stock under the $500 million multi-year common stock repurchase program that our Board of Directors authorized on August 6, 2013 (see "Possible Future Uses of Cash" below).

Net debt increased $98.5 million from December 31, 2013 to March 31, 2014 primarily due to our use of cash to repurchase shares of our common stock, capital expenditures and withholding taxes paid by us on behalf of employees in net share settlements of restricted stock, partially offset by cash provided by operating activities and proceeds from employee stock option exercises.

The change in our working capital and working capital ratio were as follows:

Working capital	$	229,356	$	353,528	$	(124,172	)
Working capital ratio	1.76		2.14		N/A

The decrease in working capital is primarily a result of repurchases of our common stock, capital spending and withholding taxes paid by us on behalf of employees in net share settlements of restricted stock, somewhat offset by cash provided by operations, timing of payments to vendors and employees and proceeds from employee stock option exercises.

Cash Flow Activity

Cash and cash equivalents were $178.8 million and $731.7 million as of March 31, 2014 and 2013, respectively. In addition, we had investments of $176.4 million and $181.6 million as of March 31, 2014 and 2013, respectively, which were short-term in nature and generally available to fund our operations.

Cash Flow from Operating Activities

The increase in cash provided by operating activities in the three months ended March 31,2014 compared to the three months ended March 31,2013 primarily related to changes in working capital, which were largely due to the timing of interest payments as a result of the 2013 financing activities discussed below, payments to vendors and collection of receivables.

Cash Flow from Investing Activities

The change in cash used in investing activities in the three months ended March 31,2014 compared to the three months ended March 31,2013 was primarily the result of a net increase in proceeds from the sale and purchase of investments in 2014, somewhat offset by higher capital expenditures in 2014. Our balances of cash, cash equivalents and investments fluctuate over time based on our cash requirements and market interest yields. Cash used for capital expenditures for the three months ended March 31,2014 was $101.6 million, the majority of which was success-based (see "Capital Expenditures and Requirements" below) compared to $87.8 million for the three months ended March 31,2013.

Cash Flow from Financing Activities

Cash used in financing activities for the three months ended March 31,2014 primarily consisted of the following:

• Repurchases of $104.2 million of our common stock;

• Redemption of the remaining 2018 Notes for $24.4 million (including $0.9 million of redemption premiums);

• Withholding taxes paid by us on behalf of employees in net share settlements of restricted stock of $18.9 million; and

• Payments of $2.8 million on the Term Loan and capital lease obligations,

partially offset by:

• Proceeds of $8.5 million from employee exercises of stock options.

Cash used in financing activities for the three months ended March 31,2013 primarily consisted of the following:

• Repurchases of $54.6 million of our common stock;

• Withholding taxes paid by us on behalf of employees in net share settlements of restricted stock of $18.3 million; and

• Payments of $1.7 million on the Term Loan and capital lease obligations,

partially offset by:

• Proceeds of $24.4 million from employee exercises of stock options.

Our financing activities from January 1, 2013 through the three months ended March 31, 2014 were comprised of the following:

• In April 2013, we refinanced our outstanding $461.8 million Term Loan due December 2016 and replaced an undrawn $80 million revolving credit facility expiring December 2014 with a new senior secured credit facility consisting of a $520 million Term Loan due April 2020 and an undrawn $100 million Revolver expiring April 2018. Principal and interest payments on the Term Loan and Revolver, if drawn, are as follows:

• Repayments of the Term Loan are due quarterly in an amount equal to 0.25% of the aggregate principal amount on the last day of each quarter commencing September 30, 2013. Interest on the Term Loan is computed based on a specified Eurodollar rate plus 2.5%. Interest is reset periodically and payable at least quarterly. Based on the Eurodollar rate in effect at March 31, 2014, the effective interest rate was 2.66%.

• Interest on outstanding amounts under the Revolver, if any, will be computed based on a specified Eurodollar rate plus 1.75% to 2.75% and will be reset periodically and payable quarterly. The Company is required to pay a commitment fee on the undrawn commitment amounts on a quarterly basis of 0.375% to 0.5% per annum. The new senior secured credit facility contains customary affirmative and negative covenants. Most of the Revolver covenants apply whether or not we draw on that facility. In addition, if the Revolver were drawn, certain financial maintenance covenants would apply.

• During the year ended December 31, 2013, we settled the $373.7 million principal amount of Convertible Debentures outstanding as of December 31, 2012 for $552.7 million in cash as a result of our redemptions and conversions by holders of the Convertible Debentures. We also used $0.5 million in cash for transaction costs associated with the retirement of the Convertible Debentures.

• In August 2013, we completed a private offering of $800 million of Senior Notes, including the 2022 Mirror Notes at an offering price of 96.250% of the $450 million principal amount and the 2023 Notes at an offering price of 100% of the $350 million principal amount. The net proceeds from the offering were used to fund the repurchase of $406.5 million principal amount of the 2018 Notes for $438.7 million and for general corporate purposes. In January 2014, we completed exchange offers in which the 2022 Mirror Notes and the 2023 Notes were exchanged for a like principal amount of registered notes with substantially identical terms. Approximately $23.5 million principal amount of the 2018 Notes remained outstanding as of December 31, 2013.

• During the three months ended March 31, 2014, we redeemed the remaining outstanding $23.5 million principal amount of 2018 Notes at a redemption price of 104% of the principal amount, which resulted in $0.9 million of premiums associated with the redemption.

c The Term Loan matures in April 2020. The principal amount is reduced by quarterly principal payments.

Capital Expenditures and Requirements

Our capital expenditures were $102.2 million in total for the three months ended March 31,2014, or $94.3 million excluding expenditures in connection with integration of the strategic market expansion into our network, compared to $90.9 million of total capital expenditures for the same period in 2013. We made the majority of capital expenditures in each period for what we deem success-based opportunities that were linked to new installations and related network capacity increases. Success-based spending generally consists of short-to-medium length capital projects, in terms of anticipated time between capital spending and return on investment, driven by customer opportunities. The increase in capital expenditures over the prior year period primarily resulted from the timing of projects, as well as expenditures in connection with integration of the strategic market expansion into our network.

In each of the years ended 2005 through 2013, over 75% of our total annual capital expenditures, excluding capital expenditures for integration of a 2006 acquisition and branding and a capital lease commitment for our strategic market expansion, were for what we deem success-based opportunities. This includes costs to connect to new customer locations with our fiber network and increase capacity in our network, IP backbone enhancements, collocation facility expansion and central office infrastructure to serve growing customer demands. These types of expenditures often fluctuate as our volume of sales and service installations increases or decreases.

For the full year 2014, we expect capital expenditures of approximately $440 million to $460 million (see “Future Sources of Cash” below for discussion of anticipated funding sources), the majority of which we expect to be related to success-based opportunities. Our anticipated capital expenditures include approximately $50 million of capital expenditures to integrate and connect the strategic market expansion fiber into our national network and operating infrastructure. Also, included in expected capital expenditures are amounts we must spend to replace older network components, especially electronics, which are expenditures that we expect will continue to grow over time. We expect quarterly fluctuations in our capital spending due to the timing of large projects and other external factors such as customer readiness, permitting and weather.

Future Sources of Cash

Based on current assumptions, we expect to generate sufficient cash from operations along with available cash on hand (including cash equivalents and investments) and borrowing capacity under our undrawn Revolver to provide sufficient funds to meet our expected capital expenditure and liquidity needs to operate our business and service our debt for the foreseeable future. However, if our assumptions prove incorrect or if there are other factors that negatively affect our cash position such as material unanticipated losses, a significant reduction in demand for our services, an acceleration of customer disconnections, or other adverse factors, or if we make acquisitions, enter into joint ventures or repurchase additional shares of our common stock, we may need to seek additional sources of funds through financing or other means. There is no assurance that other sources of financing on acceptable terms will be available in the future. Other risks, such as a rating downgrade on our debt or adverse debt market conditions, could further impact our potential access to or the cost of financing sources.

Our ability to draw upon the available commitments under our Revolver is subject to compliance with all of the covenants contained in the credit agreement and our continued ability to make certain representations and warranties. In the case of the Revolver, the covenants include financial maintenance covenants, such as leverage and interest coverage ratios and limitations on capital expenditures that are primarily derived from Modified EBITDA and debt levels. We are required to comply with these ratios as a condition to any borrowing under the Revolver and for as long as any loans are outstanding under the Revolver. The representations and warranties include the absence of liens on our properties other than certain permitted liens, the absence of litigation or other developments that have or could reasonably be expected to have a material adverse effect on us and our subsidiaries as a whole and continued effectiveness of the documents granting security for the loans.

A lack of revenue growth or an inability to control costs could negatively impact Modified EBITDA and cause our failure to meet the required minimum ratios under the Revolver if we have loans outstanding under the Revolver or wish to draw on it. Although we currently believe that we will continue to be in compliance with the covenants, various factors, including deterioration of the economy, increased competition and pricing pressure and loss of revenue from significant customers, an acceleration of customer disconnections, a significant reduction in demand for our products without adequate reductions in capital expenditures and operating expenses or an uninsured catastrophic loss of physical assets or other risk factors could cause us to fail to meet our covenants. If our revenue growth is not sufficient to sustain the Modified EBITDA performance required to meet the debt covenants described above, and we have loans outstanding under the Revolver or wish to draw on it, we would have to consider cost cutting or other measures to maintain required Modified EBITDA levels or to enhance liquidity.

The Revolver, Term Loan and Senior Notes (the "Revolver and Long-Term Debt Obligations") limit our ability to declare cash dividends, repurchase shares, incur indebtedness, incur liens on property and undertake acquisitions, among other things. The agreements governing the Revolver and Long-Term Debt Obligations also include cross-default provisions under which we are deemed to be in default if we default under any of the other material outstanding obligations. If we are in default under any of the covenants under the Term Loan and Revolver, we also could potentially be subject to an acceleration of the repayment date of the Term Loan and the Revolver if we have borrowed any amounts under that facility. If we do not comply with the covenants under the Revolver, we would not be able to draw additional funds under the Revolver and the lenders could cancel the Revolver unless the respective lenders agree to further modify the covenants. Covenant defaults under the credit agreement for the Revolver and Term Loan also may constitute an event of default under the indentures for the Senior Notes. In addition, the lenders under the Revolver may require prepayment of outstanding revolving loans if a change of control and ratings decline occurs as defined in the credit agreement. We are required to offer to prepay the Senior Notes and the Term Loan on an individual basis if a change of control and a debt rating decline occur, as defined in the indentures for the Senior Notes and the Term Loan covenants under our credit agreement. As of March 31, 2014, we were in compliance with all of our debt covenants.

Possible Future Uses of Cash

In order to mitigate potential variability in interest rates, reduce future cash interest payments, reduce principal amounts outstanding or reduce our leverage, we or our affiliates may, from time to time, enter into interest rate derivatives, purchase or redeem our outstanding Senior Notes for cash in the open market or privately negotiated transactions, or engage in other transactions to reduce the principal amount of outstanding Senior Notes. As of March 31, 2014, we had not entered into any interest rate derivative transactions. Under the terms of our Revolver, which is more restrictive than our Term Loan and the indentures for the Senior Notes, we currently may repurchase a portion of our outstanding Senior Notes if the sum of our cash and cash equivalents and borrowing availability under our Revolver is a minimum of $200 million after giving effect to the repurchase, provided that we do not use the Revolver proceeds for this purpose and we meet certain other conditions.

In August, 2013, our Board of Directors authorized a $500 million multi-year common stock repurchase program, of which approximately $112.6 million was repurchased during the three months ended March 31, 2014. As of March 31, 2014, we had repurchased $250.1 million of our common stock and a total of $249.9 million remains available under the Board's stock repurchase authorization. The repurchase authorization does not have an expiration date, but can be withdrawn by the

37

tw telecom inc.

Board at any time. Our Revolver, as amended in August 2013, permits repurchases of our common stock, or restricted payments, up to $500 million from August 9, 2013 to December 31, 2014, and thereafter $250 million annually in the aggregate if after the transaction the sum of our cash and cash equivalents and availability under our Revolver is a minimum of $200 million, we have not used that basket for other permissible purposes, including dividend payments, and we meet certain other conditions. Up to $200 million of the restricted payments capacity not used through December 31, 2014 may be carried over to the fiscal year ending December 31, 2015. For the fiscal years ending December 31, 2015 and thereafter, up to $100 million of unused restricted payments capacity may be carried over to the next subsequent fiscal year. At March 31, 2014, we had repurchased $250.1 million of our common stock of the maximum $500 million permissible under our Revolver covenants through December 31, 2014. We do not anticipate that the planned spending for our strategic market expansion will limit our ability to execute our common stock repurchase program.

We plan to evaluate additional repurchases of shares of our common stock in public or private transactions under the $500 million authorization described above based on market conditions and other considerations or may consider paying dividends to the extent permitted by our debt covenants. We may also consider merger and acquisition opportunities or other strategic transactions that could impact our cash usage. Additionally, we may increase our leverage for these purposes. We will evaluate any such transactions in light of market conditions, taking into account our liquidity and prospects for access to capital, benefits to us of any such transaction and contractual constraints. We generally expect to maintain approximately $300 million in cash, cash equivalents and short-term investments in order to provide ongoing liquidity and flexibility for other operating and strategic initiatives. The actual balance of cash, cash equivalents and short-term investments will depend on the timing of collections, payments, our business operations in general and any financing activities we may undertake and is likely to fluctuate from quarter to quarter.

Risk Management

As of March 31, 2014, our cash, cash equivalents and short-term investments were held in financial institutions, U.S. Treasury money market mutual funds, commercial paper and debt securities issued by the U.S. Treasury and other U.S. government agencies. Although we actively monitor the depository institutions, credit quality of the U.S. government and its entities and the performance and quality of our investments and the mutual funds that hold our cash and cash equivalents, we are exposed to risks resulting from deterioration in the financial condition of the U.S. government and its entities, deterioration in the financial condition or failure of financial institutions holding our cash deposits, decisions of our investment advisors and the investment managers of the money market funds and defaults in securities underlying the funds and investments. We prioritize safety over investment return in choosing the investment vehicles for cash, cash equivalents and investments and have diversified these investments to the extent practical in an effort to minimize our exposure to any one investment vehicle or financial institution. We may change the nature of our cash, cash equivalent and short-term investments as market conditions change.

Off-Balance Sheet Arrangements

As of March 31, 2014, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.
