International

Reported revenues of $30.0 million decreased $2.9 million, or 8.8%, in the first quarter of 2015 as compared to the same prior-year period due to the impact of foreign currency exchange. Organic revenues increased $1.0 million, or 3.4%, led by solid growth in Canada and Mexico.

Reported Adjusted OIBDA decreased $1.0 million to $0.1 million in the first quarter of 2015 as compared to the same prior-year period due to product and geographic mix.

Corporate

Corporate costs, excluding stock-based compensation, increased $1.7 million to $7.5 million in the first quarter of 2015 compared to the same prior-year period, including $2.0 million in strategic development costs and $2.9 million of incremental stand-alone costs, offset by lower compensation-related expenses.

Interest Expense

Net Interest expense in the first quarter of 2015 was $27.8 million, including $1.5 million of amortization of deferred financing costs, as a result of the incurrence of $1.6 billion of indebtedness on January 31, 2014, $600 million of indebtedness on October 1, 2014 related to acquisitions, and $100 million of indebtedness on March 30, 2015. The weighted average cost of debt at March 31, 2015, was 4.7%.

Income Taxes

The benefit from income taxes was $1.4 million in the first quarter of 2015 compared to a provision of $5.9 million in the first quarter of 2014. On July 17, 2014, we began operating in a manner that will allow us to qualify as a real estate investment trust (“REIT”) for U.S. federal income tax purposes. Cash paid for income taxes in the first quarter of 2015 was $1.3 million as compared to $4.8 million in the same prior-year period.

Net Income per Common Share

Net income attributable to common shareholders was $1.1 million in the first quarter of 2015 as compared to $8.4 million in the same prior-year period. Net income for the first quarter of 2015 was impacted by higher depreciation and amortization expense from acquisitions, the incurrence of interest expense, incremental stand-alone costs, strategic business development costs and restructuring charges, partially offset by contributions from higher revenue from acquisitions and lower taxes due to our conversion to a REIT. Diluted weighted average shares outstanding were 137.6 million for the first quarter of 2015. Net income per diluted weighted average share was $0.01 for the first quarter of 2015 as compared to $0.09 in the same prior-year period. Net income per diluted weighted average share on a REIT-comparable basis was $0.01 for the first quarter of 2015 as compared to $0.05 in the same prior-year period.

FFO & AFFO

FFO was $49.9 million in the first quarter of 2015, a decrease of $0.4 million from the same prior-year period, driven primarily by higher interest expense and incremental stand-alone costs, partially offset by acquisitions. FFO would have been $48.5 million in the first quarter of 2014 had we been operating as a REIT. AFFO was $49.5 million in the first quarter of 2015, an increase of $11.3 million over the same prior-year period due to acquisitions and lower income taxes due to our conversion to a REIT. AFFO would have been $43.4 million in the first quarter of 2014 had we been operating as a REIT.

Cash Flow & Capital Expenditures

Net cash flow provided by operating activities of $5.8 million for the three months ended March 31, 2015 decreased $2.0 million compared to $7.8 million during the same prior-year period due to lower net income and higher interest paid on the 2014 and 2015 debt borrowings, ,partially offset by increased non-cash charges. Total capital expenditures decreased $2.6 million to $13.1 million for the three months ended March 31, 2015.

Dividends

In the three months ended March 31, 2015, the Company paid a regular cash dividend of $46.7 million and a special cash dividend of $8.2 million representing the balance of 100% of the Company’s 2014 REIT distributable income since becoming a REIT on July 17, 2014, in excess of the regular quarterly cash dividends paid on September 30, 2014 and December 15, 2014.

The Company announced on April 30, 2015 that its board of directors has approved a quarterly cash dividend on the Company’s common stock of $0.34 per share payable on June 30, 2015, to shareholders of record at the close of business on June 11, 2015.

Non-GAAP Financial Measures

In addition to the results prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) provided throughout this document, this document and the accompanying tables include non-GAAP financial measures as described below. We calculate revenues on a constant dollar basis as reported revenues excluding the impact of foreign currency exchange rates between periods. We provide constant dollar revenues to understand the underlying growth rate of revenue excluding the impact of changes in foreign currency exchange rates between periods, which are not under management’s direct control. Our management believes constant dollar revenues are useful to users because it enables them to better understand the level of growth of our business period to period. We calculate organic revenues as reported revenues excluding revenues associated with significant acquisitions and divestitures, revenues associated with business lines we no longer operate, and the impact of foreign currency exchange rates (“non-organic revenues”). We provide organic revenues to understand the underlying growth rate of revenue excluding the impact of non-organic revenue items. Our management believes organic revenues are useful to users because it enables them to better understand the level of growth of our business period to period. We calculate Adjusted OIBDA as operating income before depreciation, amortization, net (gains) losses on dispositions, stock-based compensation and restructuring charges. We calculate Adjusted OIBDA margin by dividing Adjusted OIBDA by total revenues. Adjusted OIBDA and Adjusted OIBDA margin are among the primary measures we use for managing our business, evaluating our operating performance and planning and forecasting future periods, as each is an important indicator of our operational strength and business performance. Our management believes users of our financial data are best served if the information that is made available to them allows them to align their analysis and evaluation of our operating results along the same lines that our management uses in managing, planning and executing our business strategy. Our management also believes that the presentations of Adjusted OIBDA and Adjusted OIBDA margin, as supplemental measures, are useful in evaluating our business because eliminating certain non-comparable items highlight operational trends in our business that may not otherwise be apparent when relying solely on GAAP financial measures. It is management’s opinion that these supplemental measures provide users with an important perspective on our operating performance and also make it easier for users to compare our results with other companies that have different financing and capital structures or tax rates. We calculate FFO in accordance with the definition established by the National Association of Real Estate Investment Trusts (“NAREIT”). FFO reflects net income adjusted to exclude gains and losses from the sale of real estate assets, depreciation and amortization of real estate assets and amortization of direct lease acquisition costs, as well as the same adjustments for our equity based investments, as applicable. We calculate AFFO as FFO adjusted to include cash paid for direct lease acquisition costs as such costs are generally amortized over a period ranging from four weeks to one year and therefore are incurred on a regular basis. AFFO also includes cash paid for maintenance capital expenditures since these are routine uses of cash that are necessary for our operations. In addition, AFFO excludes costs related to restructuring charges, as well as certain non-cash items, including non-real estate depreciation and amortization, deferred income taxes, stock-based compensation expense, accretion expense, the non-cash effect of straight-line rent and amortization of deferred financing costs. We use FFO and AFFO measures for managing our business and for planning and forecasting future periods, and each is an important indicator of our operational strength and business performance, especially compared to other REITs. Our management believes users are best served if the information that is made available to them allows them to align their analysis and evaluation of our operating results along the same lines that our management uses in managing, planning and executing our business strategy. Our management also believes that the presentations of FFO, AFFO, and related per adjusted weighted average share amounts, as supplemental measures, are useful in evaluating our business because adjusting results to reflect items that have more bearing on the operating performance of REITs highlight trends in our business that may not otherwise be apparent when relying solely on GAAP financial measures. It is management’s opinion that these supplemental measures provide users with an important perspective on our operating performance and also make it easier to compare our results to other companies in our industry, as well as to REITs. We present weighted average shares on an adjusted basis for basic earnings per share (“EPS”) to give effect to the 23,000,000 shares issued on April 2, 2014, in connection with the initial public offering (the “IPO”), the 97,000,000 shares outstanding after our stock split and 16,536,001 shares issued in connection with the distribution of accumulated earnings and profits as of July 17, 2014, the date we began operating in a manner that will allow us to qualify as a REIT for U.S. federal income tax purposes (the “E&P Purge”), and on an adjusted basis for diluted EPS to also give effect to dilutive potential shares from grants of restricted share units (“RSUs”), performance-based restricted share units (“PRSUs”) and stock options. Our management believes that these presentations are useful in evaluating our business because they allow users to evaluate our basic and diluted per share results after giving effect to the issuance of shares of our common stock in connection with the IPO and the E&P Purge, which increased our outstanding shares of common stock. We calculate Adjusted OIBDA and Adjusted OIBDA margin, on a REIT-comparable basis, for the three months ended March 31, 2015 and 2014, by adjusting the three months ended March 31, 2014 to include incremental costs associated with operating as a stand-alone public company of $3.4 million, which were incurred in the three months ended March 31, 2015. We calculate operating income, net income, FFO, AFFO and related per weighted average share and per adjusted weighted average share amounts, on a REIT-comparable basis, for the three months ended March 31, 2015 and 2014, by adjusting to (1) exclude restructuring charges of $0.6 million ($0.5 million, net of tax) in the three months ended March 31, 2015, except with respect to AFFO and related per adjusted weighted average share amounts, which by definition includes this adjustment, (2) exclude net gains on dispositions incurred in the three months ended March 31, 2014 and 2015, except with respect to FFO, AFFO and related per adjusted weighted average share amounts, which by definition includes this adjustment, (3) include incremental costs associated with operating as a stand-alone public company of $3.4 million ($3.1 million, net of tax) incurred in the three months ended March 31, 2015, and one month of interest expense of $6.2 million ($6.2 million, net of tax) incurred in the three months ended March 31, 2015, relating to our entry into our term loan and our revolving credit facility, and the issuance of $800.0 million of our senior notes on January 31, 2014, (4) with respect to AFFO and related per adjusted weighted average share amounts only, include one month of amortization of deferred financing costs incurred in the three months ended March 31, 2015, of $0.4 million relating to our entry into our term loan and our revolving credit facility, and the issuance of $800.0 million of our senior notes on January 31, 2014, and (6) with respect to net income, FFO and AFFO, and related per weighted average share and per adjusted weighted average share amounts only, exclude income taxes that would not have been incurred had we been operating as a REIT in the three months ended March 31, 2014. Our management believes these adjusted presentations are useful in evaluating our business because they allow users to compare our operating performance for the three months ended March 31, 2015 against the operating performance for the three months ended March 31, 2014, taking into account certain significant costs arising as a result of our separation from CBS Corporation, as well as the REIT tax treatment that would have applied had we been operating as a REIT for the periods presented. Since constant dollar revenues, organic revenues, Adjusted OIBDA, Adjusted OIBDA margin, FFO, AFFO, adjusted weighted average shares for basic and diluted EPS, and, on a REIT-comparable basis, operating income, net income, Adjusted OIBDA, Adjusted OIBDA margin, FFO and AFFO, and, in each case, as applicable, related per weighted average share and per adjusted weighted average share amounts, are not measures calculated in accordance with GAAP, they should not be considered in isolation of, or as a substitute for, revenues, operating income, net income, weighted average shares outstanding for basic and diluted EPS, and net income per common share for basic and diluted EPS, the most directly comparable GAAP financial measures, as indicators of operating performance. These measures, as we calculate them, may not be comparable to similarly titled measures employed by other companies. In addition, these measures do not necessarily represent funds available for discretionary use and are not necessarily a measure of our ability to fund our cash needs.
