On March 28, 2018, we completed our acquisition of Aconex Limited (Aconex), a provider of cloud-based collaboration software for construction projects.

We have included the financial results of Aconex in our condensed consolidated financial statements from the date of acquisition. These results were not individually material to our condensed consolidated financial statements. The total preliminary purchase price for Aconex was approximately $1.2 billion, which consisted of approximately $1.2 billion in cash and $7 million for the fair values of stock options and restricted stock-based awards assumed. In connection with the Aconex acquisition, we have preliminarily recorded $20 million of net liabilities and $377 million of identifiable intangible assets based on their estimated fair values, and $864 million of residual goodwill. Goodwill generated from our acquisition of Aconex was primarily attributable to synergies expected to arise after the acquisition and is not expected to be tax deductible.

During the first nine months of fiscal 2019 and the full fiscal year of 2018, we acquired certain other companies and purchased certain technology and development assets primarily to expand our products and services offerings. These acquisitions were not significant individually or in the aggregate.

The preliminary fair values of net tangible assets and intangible assets acquired were based on preliminary valuations, and our estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date). The primary areas that remain preliminary relate to the fair values of intangible assets acquired, certain tangible assets and liabilities acquired, certain legal matters, income and non-income based taxes and residual goodwill. We expect to continue to obtain information to assist us in determining the fair values of the net assets acquired during the measurement period.

The unaudited pro forma financial information in the table below summarizes the combined results of operations for Oracle, Aconex and certain other companies that we acquired since the beginning of fiscal 2018 that were considered relevant for the purposes of unaudited pro forma financial information disclosure as if the companies were combined as of the beginning of fiscal 2018. The unaudited pro forma financial information for all periods presented included the business combination accounting effects resulting from these acquisitions, including amortization charges from acquired intangible assets (certain of which are preliminary), stock-based compensation charges for unvested restricted stock-based awards and stock options assumed, if any, and the related tax effects as though the aforementioned companies were combined as of the beginning of fiscal 2018. The unaudited pro forma financial information as presented below is for informational purposes only and is not necessarily indicative of the results of operations that would have been achieved if the acquisitions had taken place at the beginning of fiscal 2018.

The unaudited pro forma financial information for the three and nine months ended February 28, 2019 presented the historical results of Oracle for the three and nine months ended February 28, 2019, and certain other companies that we acquired since the beginning of fiscal 2019 based upon their respective previous reporting periods and the dates these companies were acquired by us, and the effects of the pro forma adjustments listed above.

The unaudited pro forma financial information for the three and nine months ended February 28, 2018 combined the historical results of Oracle for the three and nine months ended February 28, 2018 and the historical results of Aconex for the twelve month period ended December 31, 2017 (adjusted due to differences in reporting periods and considering the date we acquired Aconex) and certain other companies that we acquired since the beginning of fiscal 2018 based upon their respective previous reporting periods and the dates these companies were acquired by us, and the effects of the pro forma adjustments listed above.
