), a provider of global data center services, today reported quarterly results for the quarter ended June 30, 2013. The Company uses certain non-GAAP financial measures, which are described further below and reconciled to the most comparable GAAP financial measures after the presentation of our GAAP financial statements.
Revenues were $525.7 million for the second quarter, a 1% increase over the previous quarter and a 15% increase over the same quarter last year and includes a $5.8 million reduction in revenue for the second quarter due to a change in accounting estimate related to non-recurring installation fees. Recurring revenues, consisting primarily of colocation, interconnection and managed services were $502.5 million for the second quarter, a 1% increase over the previous quarter and a 16% increase over the same quarter last year. Non-recurring revenues were $23.2 million in the quarter. Churn for the second quarter was 2.4%, down from 3.7% for the previous quarter and in line with prior guidance.
Non-recurring installation fees, although generally paid in a lump sum upon installation, are deferred and recognized ratably over the expected life of the installation. During the second quarter, the Company reassessed the estimated period that revenue related to non-recurring installation fees is recognized due to its determination that its customers were generally benefitting from their installations longer than originally anticipated. For example, in North America new customer contracts have generally been lengthened from one to two years, to three years or more, which the Company believes extends the overall life of both the installation and the overall customer relationship. As a result of the Company’s analysis, the estimated period that revenue related to non-recurring installation fees is recognized has been lengthened to four years, up from two to three years. This change was accounted for as a change in accounting estimate on a prospective basis effective April 1, 2013. The change in the estimated period that revenue related to non-recurring installation fees is recognized, which has resulted in less revenue than would have otherwise been recorded, resulted in a $5.8 million reduction in revenue for the second quarter and a total estimated decrease in non-recurring revenue of $16.0 million for the full year 2013.
