Myth v. Reality

Verizon / MCI Transaction

The proposed combination of Verizon and MCI is the next logical step in the ongoing restructuring of the industry around new technologies, new services, and new providers. The combination of the two companies’ complementary assets and capabilities will decisively benefit the public interest by creating a strong new competitor for enterprise customers nationwide, enhancing investment in the nation’s critical communications infrastructure, and establishing the nation’s most advanced broadband platform, capable of delivering next-generation multimedia services in markets across the country.

Most of the parties that submitted comments on this transaction to the Federal Communications Commission (FCC) are competitive carriers that seek to block, delay, or condition the transaction based on fears that it will create a more efficient rival, or on their selfish hopes that they will benefit from the imposition of unnecessary conditions. But these competitive carriers and other commenters have failed to make a credible case against the Verizon / MCI transaction.

Ú Enterprise Market

Myth #1	Reality
The combination of Verizon with MCI and SBC with AT&T would result in a duopoly in the market for large enterprise customers.	The combined company will have an estimated 16% to 22% share of the enterprise market and will be just one of many competitors in what is widely recognized as the most competitive segment of the industry. Many providers compete for enterprise customers today, and none has a dominant market share. Competitors in the enterprise market include:
	•	Traditional domestic carriers – AT&T, Sprint, Qwest, XO, Level 3.
	•	Major foreign carriers –British Telecom, Deutsche Telekom, NTT, COLT, KPN Telecom, Equant.
	•	Systems integrators and managed service providers – IBM, EDS, Accenture, Northrup Grumman, Lockheed Martin.
	•	Equipment vendors and application providers – Lucent, Nortel, Cisco, Microsoft.

Myth #2	Reality
Verizon/MCI and SBC/AT&T would avoid engaging in head-to-head competition.	A key purpose and benefit of this transaction is the increased ability of the combined company to compete on a national and global scale, including increased competition with SBC/AT&T. Verizon and SBC already compete head-to-head today, especially in the growth areas of telecommunications – enterprise, wireless, data, and VoIP:
	•	Verizon Wireless and Cingular compete across the nation for wireless customers, and Verizon has deployed its 3G wireless broadband service (EvDO) within major metropolitan areas in SBC’s territory.
	•	Verizon competes for enterprise customers in 28 out-of-franchise areas, 17 of which are in SBC’s service areas.
	•	Verizon has deployed 300 miles of optical network facilities in Los Angeles and extended its optical fiber in Dallas to compete directly with SBC.
	•	Verizon operates an IP/MPLS backbone with routers in several SBC cities, including Chicago, Dallas-Fort Worth, Los Angeles, and San Francisco.
	•	Verizon’s VoiceWing VoIP service competes with SBC by offering area codes in 11 of SBC’s 13 states.
Myth #3	Reality
The transaction would eliminate a competitive source of local access facilities on which competitors depend.	MCI’s local fiber facilities in Verizon’s region are located in areas in which there are already competing fiber suppliers with comparable facilities. And, in every location, competing carriers are clearly capable of deploying such facilities, given that MCI itself did so. In the 39 groupings of wire centers in which Verizon and MCI have overlapping fiber, there are:
	•	A total of more than 90 different fiber suppliers.
	•	Two or more suppliers in 92% of the areas.
	•	At least one other supplier in all but one of these areas (and that one area consists of a single wire center).
	•	An average of six competing carriers in wire centers with an overlap.

	Other Fiber-Based Carriers in areas where Verizon and MCI facilities overlap
Myth #4	Reality
The combination of the two companies would increase the ability to discriminate in the provision of special access.	The FCC has repeatedly held that vertical combinations are generally pro-competitive. And the commenters have raised no credible transaction-specific arguments concerning special access. The Commission has regulatory safeguards to protect against the risk of discrimination. To the extent there are concerns about the adequacy of those rules going forward, those concerns are properly addressed in industry-wide proceedings, as has been the Commission’s consistent practice.
	The claims also lack substance. Even ignoring the regulatory safeguards, the extensive facilities-based competition in the specific areas in which MCI has deployed fiber would make it impossible for the combined company successfully to execute a price squeeze. And both the FCC and the courts have recognized that such a strategy is unlikely to be attempted, and even less likely to succeed. The FCC also repeatedly has found that its regulations adequately protect against the risk of a price squeeze

Ú Internet Backbone

Myth #5	Reality
The combined company would achieve “mega peer” status, which could harm competition for Internet backbone services.	MCI operates one of several Internet backbones of roughly similar size, while Verizon has a minor backbone. Backbone-based services are highly competitive and will remain so after the combination of the two companies.
	•	The combined firm would carry less than 10% of North American Internet traffic.
	•	The combined company would remain only the fourth largest carrier of Internet traffic – in the middle of a group of seven backbone providers of larger or comparable size.
	•	Major competitors include AT&T, Sprint, Level 3, Qwest, SAVVIS, AOL.
	•	Carriers other than the top seven providers carry about 35% of the traffic.
	The combined company’s market share could not threaten competitive harm. Indeed, any attempt to somehow disadvantage another provider would be doomed to failure because that provider could simply connect to one of a number of other backbone operators to obtain the connectivity it needs. There is no credible claim that this transaction will, in any way, harm competition for Internet backbone services.

Myth #6	Reality
The combined company would increase incentives to discriminate against unaffiliated content and application providers through its last-mile broadband facilities.	There are no credible transaction-specific arguments that the combined company might discriminate. The FCC has found that cable modem service is the broadband market leader, accounting for a substantial majority of all broadband customers. Accordingly, denying customers access to the content they want would merely cause them to switch to a competitor that offered such access. The FCC itself has explained that the competitive pressures facing companies such as Verizon, when they offer broadband services, compel them to offer faster service at lower retail prices. That is why Verizon has endorsed net neutrality principles – because they make good business sense – and why it has encouraged all providers to likewise endorse and voluntarily adhere to those principles.
Ú Mass Market
Myth #7	Reality
The transaction would eliminate a major mass-market competitor.	MCI’s position in the mass market is in continuing and irreversible decline, a result of technological, market, and regulatory developments that have compelled MCI to deemphasize its mass-market business and focus on serving its shrinking legacy customer base.
	Mass-market competition today comes not only from traditional wireline carriers, but also from a number of intermodal providers – such as cable and wireless providers, VoIP providers, e-mail, and instant messaging. Intermodal providers are major factors in the mass market now and will provide the most significant competition going forward. This intermodal competition is particularly intense in Verizon’s service area, where cable companies and others are rolling out service on a widespread basis:
	•	Cable companies will offer voice telephone services to nearly 60% of U.S. households by year-end and are expected to offer voice service to nearly 100% of homes passed over the next two to three years.
	•	Cable companies already offer voice telephone service to more than 23 million homes in Verizon’s service area alone.
	•	Cable companies have attracted 20-40% of subscribers in some markets where they offer telephone service.
		-	TimeWarner added over 150,000 customers in just the 1Q 2005.
		-	Cox added more than 110,000 customers during the same period.
		-	Cablevision added 92,000 customers just within Verizon’s service areas.

	Wireless carriers are similarly competing with wireline carriers for both lines and, even more significantly, for minutes of use:
	•	Analysts estimate that approximately 7-8% of wireless users had given up their landline phones, that wireless made up nearly 30% of voice minutes in 2004, and that 60% of long distance calls in households with wireless phones are made from wireless phones.
	•	As of year-end 2004, analysts estimate that wireless had displaced approximately 11 million wireline access lines and billions of otherwise revenue-producing minutes.
	And, both lines and minutes of use are being displaced increasingly by non-traditional sources of competition such as VoIP, as well as e-mail and instant messaging:
	•	VoIP is available to the more than 90% of U.S. homes that now have access to broadband services.
	•	If only 5% of e-mails and instant messages have substituted for a 90-second voice call, this data traffic has displaced more than 10% of the voice traffic that otherwise would have been handled by the incumbents’ networks.
Ú Public interest benefits
Myth #8	Reality
The combined company would not create significant public interest benefits.	The combination of Verizon’s and MCI’s complementary assets and expertise – together with the added investment of $2 billion in capital and $3 to $3.5 billion in total that Verizon has committed to make to MCI’s network and systems – will strongly promote the public interest:
	•	Large enterprise customers will benefit from the creation of a strong and stable new facilities-based competitor that will be capable of providing a full range of communications services to these customers nationwide.
	•	Governmental and national security customers will benefit from the strengthening of an important technology and infrastructure provider that serves the Departments of Defense and Homeland Security as well as other state and federal agencies, and from the ability to obtain a full array of existing and future services across the country.
	•	Mass-market customers will benefit from the combination of MCI’s Internet protocol network and expertise with Verizon’s ongoing deployment of the nation’s most advanced broadband networks.
	•	The economy as a whole will benefit from enhanced efficiency and innovation-producing investments, along with the creation of a strong U.S. competitor in the global marketplace.
