Lease Commitments

We have entered into various non-cancellable operating lease agreements for certain of our offices and facilities throughout the world with original lease periods expiring primarily between 2018 and 2024. Some of these agreements have escalating rent payment provisions. We recognize rent expense under such agreements on a straight-line basis.

Our rent expense under operating leases was $7.9 million in 2017, $0.6 million in 2016 and $0.4 million in 2015.

As of December 31, 2017, future minimum lease payments under our non-cancelable operating leases are as follows over each of the next five years and thereafter (in millions):



2018	$	8,775
2019	5,907
2020	4,059
2021	3,214
2022	3,105
Thereafter	6,446
Total	$	31,506

Legal Proceedings

Beginning in November 2016, purported class actions were filed in the U.S. District Court for the Northern District of Illinois against Pfizer subsidiaries, Hospira, Inc., Hospira Worldwide, Inc. and certain other defendants relating to the intravenous saline solutions part of the HIS business. Plaintiffs seek to represent classes consisting of all persons and entities in the U.S. who directly purchased intravenous saline solution sold by any of the defendants from January 1, 2013 until the time the defendants’ allegedly unlawful conduct ceases. Plaintiffs allege that the defendants’ conduct restricts output and artificially fixes, raises, maintains and/or stabilizes the prices of intravenous saline solution sold throughout the U.S. in violation of federal antitrust laws. Plaintiffs seek treble damages (for themselves and on behalf of the putative classes) and an injunction against defendants for alleged price overcharges for intravenous saline solution in the U.S. since January 1, 2013. On February 3, 2017, we completed the acquisition of the HIS business from Pfizer. This litigation is the subject of a claim for indemnification against us by Pfizer and a cross-claim for indemnification against Pfizer by us under the HIS stock and asset purchase agreement ("SAPA").

In addition, in August 2015, the New York Attorney General issued a subpoena to Hospira, Inc. requesting that the company provide information regarding certain business practices in the intravenous solutions part of the HIS business. Separately, in April 2017, we received a grand jury subpoena issued by the United States District Court for the Eastern District of Pennsylvania, in connection with an investigation by the U.S. Department of Justice, Antitrust Division. The subpoena calls for production of documents related to the manufacturing, selling, pricing and shortages of intravenous solutions, including saline, as well as communications among market participants regarding these issues. The Department of Justice investigation is the subject of cross-claims for indemnification by both us and Pfizer under the SAPA. We will coordinate with Pfizer to produce records to the New York Attorney General and the Department of Justice.

We have an ongoing dispute with a product partner that may result in a redefinition of our contractual arrangement or in the rights or remedies determined under such arrangement. We do not expect this dispute to have a material adverse effect on our financial position or results of operations.

In addition to the legal matters described above, we are from time to time involved in various legal proceedings, either as a defendant or plaintiff, most of which are routine litigation in the normal course of business. We believe that the resolution of the legal proceedings in which we are involved will not have a material adverse effect on our financial position or results of operations.

Off Balance Sheet Arrangements

In the normal course of business, we have agreed to indemnify our officers and directors to the maximum extent permitted under Delaware law and to indemnify customers as to certain intellectual property matters related to sales of our products. There is no maximum limit on the indemnification that may be required under these agreements. We have never incurred, nor do we expect to incur, any liability for indemnification.

Contingencies

We have a contractual earn-out arrangement in connection with our acquisition of the HIS business, whereby Pfizer may be entitled up to an additional $225 million in cash upon achievement of performance targets for the company for the three years ending December 31, 2019, see (Note 2: Acquisitions and Strategic Transaction Expenses). The amount to be paid cannot be determined until the earn-out period has expired.
