The following table compares active domain names ending in .com and .net managed by our Naming Services business and the approximate installed base of SSL certificates in our SSL Certificate Services business for each year presented:

Naming Services

Revenues in our Naming Services business are derived from registrations for domain names in the .com, .net, .cc, .tv, .name and .jobs domain name registries. Revenues from .tv, .cc, .name, and .jobs are not significant. For domain names registered with the .com and .net registries, we receive a fee per annual registration that is fixed pursuant to our agreements with ICANN. Changes in revenues are driven largely by increases in the number of new domain name registrations and the renewal rate for existing registrations, as well as fee increases as permitted under our agreements with ICANN. As of December 31, 2008, we have the contractual right to increase the fees for .com domain name registrations up to 7% each year during any two years over the remaining four years of our agreement with ICANN through November 30, 2012. As of December 31, 2008, we have the contractual right to increase the fees for .net domain name registrations up to 10% each year during the remaining three years of our agreement with ICANN through September 30, 2011.

During 2008, the growth in the number of domain names registered was primarily driven by continued Internet growth and adoption, though we have seen some signs of slowing growth in domain name registrations for customers engaged in the business of on-line advertising. We expect that new name registrations and renewals from customers engaged in the business of participating in on-line advertising will continue to weaken through 2009 primarily due to a decrease in earnings-per-click for those domain name holders. We expect that on-line advertising domain names will become a smaller part of our business; these names comprise approximately 7% of our active domain names zone ending in .com and .net as of December 31, 2008. Towards the end of 2008, we started seeing signs of slowing growth in new name registrations for traditional names (other than on-line advertising names) as well due to the current macro-economic environment. We expect that weakening economic conditions will contribute to slowing growth rates in 2009 for the total worldwide domain name zone as well as for the .com and .net domain name zones under our management. We are experiencing declines in on-line advertising names and slowing growth in traditional names within North America. However, we are also experiencing continued growth in international markets where we have focused efforts to develop regions for growth with potential in both our .com and .net domain name zones over time.

Our Naming Services revenues increased $102.6 million in 2008, as compared to 2007, primarily due to a 12% year-over-year increase in the number of active domain names ending in .com and .net and increases in our .com and .net registry fees in late 2007 of 7% and 10%, respectively, to $6.42 and $3.85, respectively as per our agreements with ICANN. On October 1, 2008, we increased our .com and .net domain name registry fees by 7% and 10%, respectively, to $6.86 and $4.23, respectively, as per our agreements with ICANN. Our Naming Services revenues increased $88.8 million in 2007, as compared to 2006, primarily due to a 24% year-over-year increase in the number of active domain names ending in .com and .net.

SSL Certificate Services

Revenues in our SSL Certificate Services business are derived from licensing and service fees charged to our customers for the issuance of SSL certificates that authenticate their identity to the third parties with whom they carry out secured transactions. Revenues in the SSL Certificate Services business are related to fees charged per certificate, which are based upon a number of factors, including: (i) the brand name under which the certificate is issued, which determines the level of encryption and rigor of authentication; (ii) the number of

servers authenticated, and (iii) the duration of the certification. We generally issue SSL certificates for one, two and three years, however, the majority of our customers tend to commit to shorter certifications. We have historically experienced healthy renewal rates, and have not increased prices for our SSL certificates during 2008 and 2007.

During 2008, our installed base of SSL certificates from our GeoTrust^® and thawte^® brands increased at a higher rate than our higher-priced VeriSign^® brand and as a result of this shift to lower priced brands, our average-unit-revenue decreased compared to prior periods. We expect that the number of our SSL certificates issued will continue to increase at a higher rate than the revenues recognized from our SSL Certificate Services due to the continued shift to lower-priced brands. As we have a market share leadership at the high end of the SSL certificates market, our unit growth rate for the high end is limited by the overall segment growth. In the mid and low segments, where our market share is not as strong, we expect to see good growth opportunities for market share gains as these markets are growing faster than the high end market. Our EV SSL certificate sales, while still a small portion of our SSL Certificate Services business, continue to increase as we more than doubled our units sold compared to last year. Due to the effect of the economic slowdown, however, EV SSL certificates adoption has slowed as large scale customers delay their orders. We expect the mainstream adoption of EV SSL certificates will be deferred until we see improvements in the macro-economic environment. The weakening economy is affecting our SSL Certificate Services business and, while we expect to experience growth, we expect those growth rates to decline in 2009 compared to 2008.

Our SSL Certificate Services revenues increased $42.1 million in 2008, as compared to 2007, primarily due to a 13% year-over-year increase in the installed base of SSL certificates. Our SSL Certificate Services revenues increased $46.7 million in 2007, as compared to 2006, primarily due to an 18% year-over-year increase in the installed base of SSL certificates and recognizing a full year of revenues from the GeoTrust acquisition, which was completed in late 2006.

IAS

Revenues in our IAS business are derived from one-time credential sales to customers seeking network services, and one-time set-up fees. We also charge an annual service fee based upon the number of individual users authorized by the customer to access its network and a customer support fee. Our managed PKI service is characterized by lower growth rates than other product lines within the IAS business, reflecting the greater maturity of our managed PKI service. We expect IAS revenues to continue to grow in 2009 primarily from growth in our VIP Services and Fraud Detection Services, but at a lower growth rate than 2008.

Our IAS revenues increased $8.3 million in 2008, as compared to 2007, primarily due to increased demand for our fraud detection and identity protection services. Our IAS revenues increased $11.2 million in 2007, as compared to 2006 primarily due to increased demand for our unified authentication and identity protection services.

Our expectations and trends for our core services are based on what we are observing and can project about the current macro-economic environment. Our outlook is subject to broader changes in the market and could change.
