A summary of the allocation of the total purchase consideration is presented as follows (in millions): Purchase Consideration Net Tangible Assets Acquired (Liabilities Assumed) Purchased Intangible Assets Goodwill Duo $ 2,025 $ (57 ) $ 342 $ 1,740 Others (two in total) 60 3 8 49 Total $ 2,085 $ (54 ) $ 350 $ 1,789 On September 28, 2018, we completed our acquisition of privately held Duo Security, Inc. ("Duo"), a leading provider of unified access security and multi-factor authentication delivered through the cloud. Revenue from the Duo acquisition has been included in our Security product category. The total purchase consideration related to acquisitions completed during the first six months of fiscal 2019 consisted of cash consideration. The total cash and cash equivalents acquired from these acquisitions was approximately $85 million . Total transaction costs related to acquisition and divestiture activities were $11 million and $14 million for the first six months of fiscal 2019 and fiscal 2018 , respectively. These transaction costs were expensed as incurred in general and administrative expenses ("G&amp;A") in the Consolidated Statements of Operations. The goodwill generated from acquisitions completed during the first six months of fiscal 2019 is primarily related to expected synergies. The goodwill is generally not deductible for income tax purposes. The Consolidated Financial Statements include the operating results of each acquisition from the date of acquisition. Pro forma results of operations and the revenue and net income subsequent to the acquisition date for the acquisitions completed during the first six months of fiscal 2019 have not been presented because the effects of the acquisitions, individually and in the aggregate, were not material to our financial results. Divestiture of Service Provider Video Software Solutions On October 28, 2018 , we completed the sale of the Service Provider Video Software Solutions business. This business had tangible assets of approximately $160 million (primarily comprised of accounts receivables, inventories and various other current and long-term assets) and net intangible assets and goodwill (based on relative fair value) of $340 million . In addition, the business had total liabilities of approximately $200 million (primarily comprised of deferred revenue and various other current and long-term liabilities). We recognized an immaterial gain from this transaction in the second quarter of fiscal 2019. We completed two divestitures during the second quarter of fiscal 2018. The financial statement impact of these divestitures was not material for the second quarter and first six months of fiscal 2018. Acquisition of Luxtera On February 6, 2019 , we completed our acquisition of Luxtera, Inc. ("Luxtera"), a semiconductor company, for total consideration of approximately $660 million in cash and assumed equity awards. Revenue from the Luxtera acquisition will be included in our Infrastructure Platforms product category. We expect that most of the purchase price will be allocated to goodwill and purchased intangible assets.
