This fall, we will reach one of the most important moments in Madison Square Garden’s history as we debut a completely transformed arena that will continue to deliver multiple benefits for our company. This will be followed early next calendar year with the re-opening of a revitalized Forum arena, which will mark the company’s venue expansion to the West Coast. This is an exciting time for our company and, looking ahead, we feel confident that the successful completion of these significant capital investments, along with our strong balance sheet, will leave us well positioned to pursue opportunities to drive continued growth over the long-term.”

Results from Operations

Segment results for the quarters ended June 30, 2013 and 2012 are as follows:

Note: Does not foot due to rounding

MSG Media

For fiscal 2013 as compared to the prior year, MSG Media revenues of $677.7 million increased 10%. The increase in revenues was primarily due to an increase in affiliation fee revenue and, to a lesser extent, an increase in advertising revenue and other net increases. AOCF of $349.5 million increased 35% and operating income of $328.6 million increased 44%, both primarily due to the increase in revenues and a decrease in direct operating expenses.

For the fiscal 2013 fourth quarter as compared to the prior year period, MSG Media revenues of $176.8 million grew 6%. Affiliation fee revenue increased $7.1 million, primarily attributable to higher affiliation rates. Advertising revenue increased $5.8 million, primarily due to higher advertising revenue at both MSG Networks and Fuse. Other revenues decreased $3.1 million, primarily due to the expiration of a short-term programming licensing agreement in April 2013. Fourth quarter AOCF of $81.8 million increased 24% and operating income of $77.6 million increased 30%, primarily due to the increase in revenues and a decrease in direct operating expenses. The decrease in direct operating expenses was primarily due to lower programming expenses at Fuse, partially offset by higher programming expenses at MSG Networks and other net increases.

MSG Entertainment

For fiscal 2013 as compared to the prior year, MSG Entertainment revenues of $252.2 million decreased 4%. The decrease in revenues was primarily due to lower overall event-related revenues at the Company’s venues and lower revenues for the Radio City Christmas Spectacular franchise, primarily as a result of Superstorm Sandy’s impact on attendance in New York, partially offset by higher suite rental fee revenue, venue-related sponsorship and signage revenues and other net increases. AOCF decreased by $15.5 million to a loss of $10.2 million and operating loss of $24.7 million increased by $15.4 million, both primarily due to the decrease in revenues and, to a lesser extent, higher selling, general and administrative expenses. Fiscal 2013 results were also impacted by operating expenses related to the Forum, which was not open for events during the year, as well as by a $5.0 million impairment charge related to a production of the Radio City Christmas Spectacular that played in three markets outside of New York.

For the fiscal 2013 fourth quarter as compared to the prior year period, MSG Entertainment revenues of $34.8 million decreased 31%. The decrease was primarily due to lower event-related revenues at the Company’s venues, mainly the result of fewer theater events, inclusive of fewer promoted events, partially offset by higher suite rental fee revenue and venue-related sponsorship and signage revenues. Fourth quarter AOCF loss of $14.6 million increased $9.3 million and operating loss of $17.8 million increased $9.2 million, primarily due to the decrease in revenues, partially offset by lower direct operating expenses. The decrease in direct operating expenses was primarily due to fewer events in the Company’s venues, partially offset by higher venue operating costs, primarily for Radio City Music Hall, the Forum, The Garden and The Theater at Madison Square Garden, and other net expense increases.

MSG Sports

For fiscal 2013 as compared to the prior year, MSG Sports revenues of $470.3 million increased 1%. The increase in revenues was due to higher suite rental fee revenue and professional sports team sponsorship and signage revenues, mostly offset by lower professional sports team ticket-related revenue, event-related revenues from other live sporting events, professional sports team food, beverage and merchandise sales, and other net decreases. AOCF of $27.0 million decreased 6%, due to an increase in selling, general and administrative and direct operating expenses, mostly offset by the increase in revenues. Operating income of $13.5 million increased 3%, due to the increase in revenues and lower depreciation and amortization expense, mostly offset by higher selling, general and administrative and direct operating expenses.

For the fiscal 2013 fourth quarter as compared to the prior year period, MSG Sports revenues of $140.7 million increased 7%. Segment revenues were positively impacted by the New York Rangers’ compressed regular season schedule in the quarter as a result of the NHL work stoppage. In addition, the comparability of segment revenues to the prior year period was negatively impacted by the New York Knicks’ compressed regular season schedule in the prior year quarter as a result of the NBA work stoppage. On an overall basis, the increase in revenues was primarily due to higher suite rental fee revenue, sponsorship and signage revenues, and professional sports team food, beverage and merchandise sales, partially offset by lower league distributions. In addition, event-related revenues from other live sporting events increased, while professional sports team playoff-related revenues slightly decreased. Fourth quarter AOCF of $28.4 million increased 43% and operating income of $25.8 million increased 61%, both primarily due to higher revenues, slightly offset by higher direct operating expenses.

Non-GAAP Financial Measures

We define adjusted operating cash flow (“AOCF”), which is a non-GAAP financial measure, as operating income (loss) before 1) depreciation, amortization and impairments of property and equipment and intangible assets, 2) share-based compensation expense or benefit, and 3) restructuring charges or credits. Because it is based upon operating income (loss), AOCF also excludes interest expense (including cash interest expense) and other non-operating income and expense items. We believe that the exclusion of share-based compensation expense or benefit allows investors to better track the performance of the various operating units of our business without regard to either the distortive effects of fluctuating stock prices or the settlement of an obligation that is not expected to be made in cash.

We believe AOCF is an appropriate measure for evaluating the operating performance of our business segments and the company on a consolidated basis. AOCF and similar measures with similar titles are common performance measures used by investors and analysts to analyze our performance. Internally, we use revenues and AOCF measures as the most important indicators of our business performance, and evaluate management’s effectiveness with specific reference to these indicators. AOCF should be viewed as a supplement to and not a substitute for operating income (loss), net income (loss), cash flows from operating activities, and other measures of performance and/or liquidity presented in accordance with U.S. generally accepted accounting principles (“GAAP”). Since AOCF is not a measure of performance calculated in accordance with GAAP, this measure may not be comparable to similar measures with similar titles used by other companies. For a reconciliation of AOCF to operating income (loss), please see page 5 of this release.
