2007 was driven by the continued conversion to Neulasta?
from NEUPOGEN?
and changes in foreign exchange, which positively impacted the growth in combined international sales by $74 million.
Excluding the impact of foreign currency exchange rate changes, combined international Neulasta?/NEUPOGEN?
sales increased 13%.
In addition to the factors mentioned in the “Product sales” section above, future worldwide Neulasta?/ NEUPOGEN?
sales will be dependent, in part, on such factors as: ?
penetration of existing segments; ?
competitive products or therapies, including biosimilar products that have been or may be approved and launched in the EU (see “Item 1.  Business — Marketed Products and Selected Product Candidates” for additional discussion); ?
the availability, extent and access to reimbursement by government and third-party payors; ?
adverse events or results from clinical trials or studies or meta-analyses performed by us or by others (including our licensees or independent investigators), which could impact product safety labeling and may negatively impact healthcare provider prescribing behavior, use of our products, regulatory or private healthcare organization medical guidelines and reimbursement practices; ?
governmental or private organization regulations or guidelines relating to the use of our products; ?
cost containment pressures from governments and private insurers on healthcare providers; ?
our current and future contracting and related pricing strategies; ?
patient population growth; and ?
development of new treatments for cancer and future chemotherapy treatments.
For example, targeted therapies and other treatments that are less myelosuppressive, and changes in chemotherapy usage patterns, may require less Neulasta?/NEUPOGEN?.
See “Item 1.  Business — Key Developments” and “Item 1A.
Risk Factors” for further discussion of certain of the above factors that could impact our future product sales.
ENBREL For the years ended December 31, 2008, 2007 and 2006, total ENBREL sales by geographic region were as follows (dollar amounts in millions):
## Table 0 ##
ENBREL sales growth for the year ended December 31, 2008 reflects higher demand principally due to increases in average net sales price.
ENBREL sales were also favorably impacted by approximately $100 million due to a change in our distribution model for ENBREL.
Previously, ENBREL was shipped directly to pharmacies.
However, beginning in the three months ended March 31, 2008, we commenced using a wholesaler distributor model, similar to our other marketed products.
Also, ENBREL sales growth for the year ended December 31, 2008 was affected by share declines in the rheumatology and dermatology segments in the United States compared to the prior year due to increased competitive activity.
However, sales growth continued in both rheumatology and dermatology, and ENBREL continues to maintain a leading position in both segments.
ENBREL sales growth for the year ended December 31, 2007 was driven by demand due to increases in both patients and average net sales price.
While ENBREL continued to maintain a leading position in both rheumatology and dermatology, the sales growth during the year ended December 31, 2007 was affected by slight share declines in the United States in both segments compared to the prior year due to increased competitive activity.
Year Ended December 31, 2014 Compared to Year Ended December 31, 2013 Revenue:
## Table 1 ##
The Company’s revenue increased 8.7% during the year ended December 31, 2014 as compared to the year ended December 31, 2013, including increases in all major revenue categories.
The growth was partially influenced by benefits from the Company’s continued investment in its global sales and marketing organization.
Revenue from lease licenses increased 6.8% as compared to the prior year due primarily to growth in lease license revenue of power analysis and electronics products.
Perpetual license revenue, which is derived primarily from new sales, increased 6.6% as compared to the prior year.
Annual maintenance contracts that were sold with new perpetual licenses, along with maintenance contracts sold with new perpetual licenses in previous years, contributed to maintenance revenue growth of 12.2%.
With respect to revenue, on average for the year ended December 31, 2014, the U. S.  Dollar was 1.6% stronger, when measured against the Company’s primary foreign currencies, than for the year ended December 31, 2013.
The net overall strengthening resulted in decreased revenue of $7.6 million during the year ended December 31, 2014 as compared to the year ended December 31, 2013.
The impact on revenue was primarily driven by $9.8 million of adverse impact due to a weakening Japanese Yen, partially offset by $1.9 million of favorable impact due to a strengthening British Pound.
The net overall strengthening of the U. S.  Dollar also resulted in decreased operating income of $5.1 million during the year ended December 31, 2014 as compared to the year ended December 31, 2013.
A substantial portion of the Company’s license and maintenance revenue is derived from annual lease and maintenance contracts.
These contracts are generally renewed on an annual basis and typically have a high rate of customer renewal.
In addition to the recurring revenue base associated with these contracts, a majority of customers purchasing new perpetual licenses also purchase related annual maintenance contracts.
As a result of the significant recurring revenue base, the Company’s license and maintenance revenue growth rate in any period does not necessarily correlate to the growth rate of new license and maintenance contracts sold during that period.
To the extent the rate of customer renewal for lease and maintenance contracts is high, incremental lease contracts, and maintenance contracts sold with new perpetual licenses, will result in license and maintenance revenue growth.
Conversely, if the rate of renewal for these contracts is adversely affected by economic or other factors, the Company’s license and maintenance growth will be adversely affected over the term that the revenue for those contracts would have otherwise been recognized.
International and domestic revenues, as a percentage of total revenue, were 65.8% and 34.2%, respectively, during the year ended December 31, 2014, and 66.1% and 33.9%, respectively, during the year ended December 31, 2013.
The Company derived 24.9% and 25.3% of its total revenue through the indirect sales channel for the years ended December 31, 2014 and 2013, respectively.
In valuing deferred revenue on the balance sheets of the Company's recent acquisitions as of their respective acquisition dates, the Company applied the fair value provisions applicable to the accounting for business combinations, resulting in a reduction of deferred revenue as compared to its historical carrying amount.
As a result, the Company's post-acquisition revenue will be less than the sum of what would have otherwise been reported by ANSYS and its subsidiaries absent the acquisitions.
The impact on reported revenue for the year ended December 31, 2014 was $5.4 million.
The expected impact on reported revenue is $1.2 million for the year ending December 31, 2015.
Ceramic Segment – Operating income was $351.1 million (11.6% of segment net sales) for 2014 reflecting an increase of $141.3 million, or 67.3%, compared to operating income of $209.8 million (7.8% of segment net sales) for 2013.

## Table 2 ##
REALTY INCOME CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements, Cont’d DECEMBER 31, 2012, 2011 AND 2010 Allocation of the Purchase Price of Real Estate Acquisitions.
When acquiring a property, we allocate the fair value of real estate acquired to: (1) land, (2) building and improvements, and (3) identified intangible assets and liabilities, based in each case on their estimated fair values.
Intangible assets and liabilities consist of above-market or below-market lease value of in-place leases, the value of in-place leases, and tenant relationships, as applicable.
In addition, any assumed mortgages payable are recorded at their estimated fair values.
Our estimated fair value determinations are based on management’s judgment, which is based on various factors, including: (1) market conditions, (2) industry that the tenant operates in, (3) characteristics of the real estate, i. e. : location, size, demographics, value and comparative rental rates, (4) tenant credit profile, (5) store profitability and the importance of the location of the real estate to the operations of the tenant’s business, and/or (6) real estate valuations, prepared either internally or by an independent valuation firm.
When real estate valuations are utilized, the measurement of fair value related to the allocation of the purchase price of real estate acquisitions is derived principally from observable market data (and thus should be categorized as level 2 on FASB’s three-level valuation hierarchy).
Our other methodologies for measuring fair value related to the allocation of the purchase price of real estate acquisitions (except for independent third-party real estate valuations) include unobservable inputs that reflect our own internal assumptions and calculations (and thus should be categorized as level 3 on FASB’s three-level valuation hierarchy).
The fair value of the tangible assets of an acquired property with an in-place operating lease (which includes land and buildings/improvements) is determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land and buildings/improvements based on our determination of the fair value of these assets.
Our fair value determinations are based on a real estate valuation for each property, prepared either internally or by an independent valuation firm, and consider estimates of carrying costs during the expected lease-up periods, current market conditions, as well as costs to execute similar leases.
In allocating the fair value to identified intangibles for above-market or belowmarket leases, an amount is recorded based on the present value of the difference between (i) the contractual amount to be paid pursuant to the in-place lease and (ii) our estimate of fair market lease rate for the corresponding in-place lease, measured over the remaining term of the lease.
Capitalized above-market lease values are amortized as a reduction of rental income over the remaining terms of the respective leases.
Capitalized below-market lease values are amortized as an increase to rental income over the remaining terms of the respective leases and expected below-market renewal option periods.
The aggregate value of other acquired intangible assets consists of the fair value of in-place leases and tenant relationships, as applicable.
The value of in-place leases, exclusive of the value of above-market and below-market in-place leases, is amortized to expense over the remaining periods of the respective leases.
The following table presents the impact during the next five years and thereafter related to the net decrease to rental revenue from the amortization of the acquired above-market and below-market lease intangibles and the increase to amortization expense from the amortization of the in-place lease intangibles for properties owned at December 31, 2012 (in thousands):
