(1) At December 31, 2017 and 2016, projects in progress included approximately $111 million and $38 million of project construction costs capitalized pursuant to build-to-suit lease guidance, which were incurred by the landlord, as property and equipment, net with a related construction financing obligation in other long-term liabilities. The building assets will begin depreciating when the costs incurred related to the build out of the office space are complete and ready for their intended use, which is expected to be in 2018.
