international networks , consisting primarily of international television networks and websites ; and education and other , consisting principally of curriculum-based product and service offerings and postproduction audio services . u.s. networks u.s. networks generated net revenues of $ 2,619 million during 2011 , which represented 62 % of our total consolidated net revenues . this segment wholly owns and operates nine national television networks , including fully distributed television networks such as discovery channel , tlc and animal planet . in addition , this segment holds our interests in own , the hub , and 3net , which are networks operated by equity method investees . we account for our interests in the underlying ventures using the equity method and services provided to them as other revenue . u.s. networks generates revenues from fees charged to distributors of our network content , which include cable and dth satellite service providers and digital distributors , from advertising sold on our television networks and other arrangements . distribution fees are largely based on the number of subscribers receiving our programming . distribution revenues are recognized net of incentives we provide to operators in exchange for carrying our networks . incentives may include launch incentives , providing the channel to the distributor for free for a predetermined length of time , or both . launch incentives are capitalized as assets upon launch of our network by the operator and are amortized on a straight-line basis as a reduction of revenue over the term of the contract , including free periods . advertising revenues are dependent upon a number of factors including the number of subscribers to our channels , viewership demographics , the popularity of our programming , and our ability to sell commercial time over a group of channels . our u.s. networks segment also generates income to offset expenses associated with providing affiliate and advertising sales representation and network services for equity method investee networks and the licensing of our brands for consumer products . during 2011 , distribution , advertising , and other revenues were 45 % , 51 % , and 4 % , respectively , of total net revenues for this segment . the discovery channel , tlc and animal planet collectively generated 72 % of u.s. networks ' total net revenues . u.s. networks ' largest single cost is content expense , including content amortization , content impairments and production costs . u.s. networks amortizes the cost of capitalized content rights based on the proportion that current estimated revenues bear to the estimated remaining total lifetime revenues , which normally results in an accelerated amortization method over the estimated useful lives . certain networks utilize a straight-line method of amortization over the estimated useful lives of the content . on january 1 , 2011 , we contributed the domestic discovery health network to own . the contribution included affiliate relationships with cable operators and dth satellite service providers , content licenses , and website user information . story_separator_special_tag this incremental tax expense will be partially mitigated by the company 's ability to utilize foreign tax credits for taxes which were deducted in prior years . as a result , the company recognized an income tax benefit of $ 112 million in the fourth quarter of 2011 related to the foreign tax credits , which were previously not considered realizable . due to the lower statutory and negotiated tax rates in the foreign corporations ' jurisdictions , the company expects a favorable impact on the effective tax rate in the future under the new operating structure . our effective tax rate for 2010 differed from the federal statutory rate of 35 % due primarily to the reversal of a $ 28 million foreign tax reserve as a result of a foreign tax authority completing its tax audit and providing us notification that certain tax years will not be adjusted and production activity deductions , which were partially offset by state taxes .
