As of December 31, 2019 and 2018, our recorded capitalized software development costs, net of accumulated amortization, which have been placed in service were $893 million and $829 million. For the years ended December 31, 2019, 2018 and 2017, we recorded amortization of capitalized software development costs of $556 million, $479 million and $398 million, most of which is included in technology and content expenses.

As of December 31, 2018, prior to our adoption of the new accounting guidance for leasing arrangements, property and equipment, net included build-to-suit assets of $152 million primarily within buildings and leasehold improvements with corresponding liabilities recorded in other long-term liabilities and, for the current portion, in accrued expenses and other current liabilities. With the adoption of the new lease accounting guidance, on January 1, 2019, we removed the assets and liabilities previously recorded pursuant to build-to-suit lease guidance.

During 2015, we acquired our future corporate headquarters for $229 million, consisting of multiple office and lab buildings located in Seattle, Washington. The build out of the headquarters has been significant as we converted lab facilities into office space. During the fourth quarter of 2019, we moved into a portion of our corporate headquarters and began depreciating the buildings in use using the straight-line method, over a useful life of 40 years.

As of December 31, 2019, 2018 and 2017, we had $34 million, $55 million and $22 million, respectively, included in accounts payable for the acquisition of property and equipment, which is considered a non-cash investing activity in the consolidated statements of cash flows.
