_________________________________________ ( 1 ) non-deductible for tax-purposes . identifiable intangible assets 2014customer relationships consist of marketo 2019s contractual relationships and customer loyalty related to their enterprise and commercial customers as well as technology partner relationships . the estimated fair value of the customer contracts and relationships was determined based on projected cash flows attributable to the asset . purchased technology acquired primarily consists of marketo 2019s cloud-based engagement marketing software platform . the estimated fair value of the purchased technology was determined based on the expected future cost savings resulting from ownership of the asset . backlog relates to subscription contracts and professional services . non-compete agreements include agreements with key marketo employees that preclude them from competing against marketo for a period of two years from the acquisition date . trademarks include the marketo trade name , which is well known in the marketing ecosystem . we amortize the fair value of these intangible assets on a straight-line basis over their respective estimated useful lives . goodwill 2014approximately $ 3.46 billion has been allocated to goodwill , and has been allocated in full to the digital experience reportable segment . goodwill represents the excess of the purchase price over the fair value of the underlying acquired net tangible and intangible assets . the factors that contributed to the recognition of goodwill included securing buyer-specific synergies that increase revenue and profits and are not otherwise available to a marketplace participant , acquiring a talented workforce and cost savings opportunities . net liabilities assumed 2014marketo 2019s tangible assets and liabilities as of october 31 , 2018 were reviewed and adjusted to their fair value as necessary . the net liabilities assumed included , among other items , $ 100.1 million in accrued expenses , $ 74.8 million in deferred revenue and $ 182.6 million in deferred tax liabilities , which were partially offset by $ 54.9 million in cash and cash equivalents and $ 72.4 million in trade receivables acquired . deferred revenue 2014included in net liabilities assumed is marketo 2019s deferred revenue which represents advance payments from customers related to subscription contracts and professional services . we estimated our obligation related to the deferred revenue using the cost build-up approach . the cost build-up approach determines fair value by estimating the direct and indirect costs related to supporting the obligation plus an assumed operating margin . the sum of the costs and assumed operating profit approximates , in theory , the amount that marketo would be required to pay a third party to assume the obligation . the estimated costs to fulfill the obligation were based on the near-term projected cost structure for subscription and professional services . as a result , we recorded an adjustment to reduce marketo 2019s carrying value of deferred revenue to $ 74.8 million , which represents our estimate of the fair value of the contractual obligations assumed based on a preliminary valuation. .
