Revenue from training, support and other services is recognized as the services are performed.
The Company applies the specific performance method to contracts in which the service consists of a single act, such as providing a training class to a customer, and the proportional performance method to other service contracts that are longer in duration and often include multiple acts (for example, both training and consulting).
In applying the proportional performance method, the Company typically utilizes output-based estimates for services with contractual billing arrangements that are not based on time and materials, and estimates output based on the total tasks completed as compared to the total tasks required for each work contract.
Input-based estimates are utilized for services that involve general consultations with contractual billing arrangements based on time and materials, utilizing direct labor as the input measure.
The Company also executes arrangements through independent channel partners in which the channel partners are authorized to market and distribute the Company’s software products to end end-users of the Company’s products and services in specified territories.
In sales facilitated by channel partners, the channel partner bears the risk of collection from the end-user customer.
The Company recognizes revenue from transactions with channel partners when the channel partner submits a written purchase commitment, collectibility from the channel partner is probable, a signed license agreement is received from the end-user customer and delivery has occurred, provided that all other revenue recognition criteria are satisfied.
Revenue from channel partner transactions is the amount remitted to the Company by the channel partners.
This amount includes a fee for PCS that is compensation for providing technical enhancements and the second level of technical support to the end-user, which is based on the rate charged for PCS when sold separately, and is recognized over the period that PCS is to be provided.
The Company does not offer right of return, product rotation or price protection to any of its channel partners.
Non-income related taxes collected from customers and remitted to governmental authorities are recorded on the consolidated balance sheet as accounts receivable and accrued expenses.
The collection and payment of these amounts are reported on a net basis in the consolidated statements of income and do not impact reported revenues or expenses.
The Company warrants to its customers that its software will substantially perform as specified in the Company’s most current user manuals.
The Company has not experienced significant claims related to software warranties beyond the scope of maintenance support, which the Company is already obligated to provide, and consequently the Company has not established reserves for warranty obligations.

## Table 1 ##
The Company’s revenue increased 7.9% in 2013 as compared to 2012, including increases in all major revenue categories.
The Company's revenue included Esterel operations for the full year in 2013 of $18.8 million as compared to five months in 2012 of $3.3 million.
The growth was partially influenced by benefits from the Company’s continued investment in its global sales and marketing organization.
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%.
Revenue from lease licenses increased 6.6% as compared to the prior year due to an increase in power-analysis-related lease license revenue and growth in sales of other lease licenses.
Perpetual license revenue, which is derived entirely from new sales during the period, increased 3.9% as compared to the prior year, due to increased perpetual license sales across most product lines, as well as a full year of Esterel activity in 2013 as compared to five months in 2012.
Service revenue increased 12.5% as compared to the prior year due to an increase in engineering consulting projects.
With respect to revenue, on average for the year ended December 31, 2013, the U. S.  Dollar was 4.0% stronger, when measured against the Company’s primary foreign currencies, than for the year ended December 31, 2012.
The net overall strengthening, primarily related to the Japanese Yen, resulted in decreased revenue and operating income during 2013, as compared to 2012, of $17.6 million and $12.2 million, respectively.
International and domestic revenues, as a percentage of total revenue, were 66.1% and 33.9%, respectively, during the year ended December 31, 2013, and 66.7% and 33.3%, respectively, during the year ended December 31, 2012.
The Company derived 25.3% and 26.0% of its total revenue through the indirect sales channel for the years ended December 31, 2013 and 2012, respectively.
In valuing deferred revenue on the Esterel and Apache Design, Inc.  ("Apache") balance sheets as of their respective acquisition dates, the Company applied the fair value provisions applicable to the accounting for business combinations, resulting in lower amounts of revenue than Esterel and Apache would have recognized absent the acquisitions.
The impact on reported revenue for the year ended December 31, 2013 was $4.6 million.
Table of Contents Other Expense, net: The Company's other expense consists of the following:
## Table 2 ##
Income Tax Provision: The Company recorded income tax expense of $77.2 million and had income before income taxes of $322.5 million for the year ended December 31, 2013, representing an effective tax rate of 23.9%.
During the year ended December 31, 2012, the Company recorded income tax expense of $90.1 million and had income before income taxes of $293.5 million, representing an effective tax rate of 30.7%.
In December 2013, the Company received notice from the IRS that the Joint Committee on Taxation took no exception to the Company's tax returns that were filed for 2009 and 2010.
An $11.0 million tax benefit was recognized in the Company's 2013 financial results as the Company had effectively settled uncertainty regarding the realization of refund claims filed in connection with the 2009 and 2010 returns.
In the U. S. , which is the largest jurisdiction where the Company receives such a tax credit, the availability of the research and development credit expired at the end of the 2011 tax year.
In January 2013, the U. S.  Congress passed legislation that reinstated the research and development credit retroactive to 2012.
The income tax provision for the year ended December 31, 2013 includes approximately $2.3 million related to the reinstated research and development credit for 2012 activity.
The decrease in the effective tax rate from the prior year is primarily due to the release of an uncertain tax position mentioned above, the reinstatement of the U. S.  research and development credit mentioned above, and cash repatriation activities.
When compared to the federal and state combined statutory rate, the effective tax rates for the years ended December 31, 2013 and 2012 were favorably impacted by lower statutory tax rates in many of the Company’s foreign jurisdictions, the domestic manufacturing deduction and tax benefits associated with the merger of the Company’s Japan subsidiaries in 2010.
