Contract Obligations As of December 31, 2020, the Company had outstanding total non-cancelable purchase obligations of $86.0 million. The Company expects to fulfill our commitments under these agreements in the normal course of business, and as such, no liability has been recorded. The unconditional purchase obligations consisted of the following (in thousands):

Some of the Company’s license agreements provide for periodic maintenance fees over specified time periods, as well as payments by the Company upon the achievement of development, regulatory and commercial milestones. Future milestone payments for research and pre-clinical stage development programs consisted of up to approximately $10.9 million in total potential future milestone payments under the Company’s license agreements with Dana-Farber Cancer Institute, University of Miami and Medarex, Inc. These milestone payments generally become due and payable only upon the achievement of certain developmental, clinical, regulatory and/or commercial milestones. The event triggering such payment or obligation has not yet occurred. Legal Proceedings From time to time, the Company is a party to various legal actions, both inside and outside the U.S., arising in the ordinary course of its business or otherwise. The Company accrues amounts, to the extent they can be reasonably estimated, that the Company believes will result in a probable loss (including, among other things, probable settlement value), to adequately address any liabilities related to legal proceedings and other loss contingencies. A loss or a range of loss is disclosed when it is reasonably possible that a material loss will incur and can be estimated, or when it is reasonably possible that the amount of a loss, when material, will exceed the recorded provision. On April 20, 2020, in response to an invalidation action brought against certain FibroGen United Kingdom patents by Akebia, the United Kingdom court handed down a decision invalidating United Kingdom designations of European Patent Nos. 1463823, 1633333, 2298301, 2322153, and 2322155. The United Kingdom designation to European Patent No. 2289531 was held to be valid in amended form, but not infringed by Akebia. The Company and its partner Astellas have filed an appeal of the decision in the United Kingdom Court of Appeal. The Company did not have material accruals for any currently active legal action in its consolidated balance sheets as of December 31, 2020, as it could not predict the ultimate outcome of these matters, or reasonably estimate the potential exposure. Indemnification Agreements The Company enters into standard indemnification arrangements in the ordinary course of business, including for example, service, manufacturing and collaboration agreements. Pursuant to these arrangements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, including in connection with intellectual property infringement claims by any third party with respect to its technology. The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The Company has entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers to the extent permissible under applicable law. The maximum potential amount of future payments the Company could be required to make under these arrangements is not determinable. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these arrangements is minimal.
