15.	Guarantees

In disposing of assets or businesses, the Company has historically provided representations, warranties and indemnities to cover various risks and liabilities, including unknown damage to the assets, environmental risks involved in the sale of real estate, liability to investigate and remediate environmental contamination at waste disposal sites and manufacturing facilities, and unidentified tax liabilities related to periods prior to disposition. The Company assesses the probability of potential liabilities related to such representations, warranties and indemnities and adjusts potential liabilities as a result of changes in facts and circumstances. The Company believes, given the information currently available, that their ultimate resolutions will not have a material adverse effect on its financial condition, results of operations and cash flows.

In connection with the sale of Mallinckrodt Baker in fiscal 2010, the Company agreed to indemnify the purchaser with respect to various matters, including certain environmental, health, safety, tax and other matters. The indemnification obligations relating to certain environmental, health and safety matters have a term of 17 years from the sale, while some of the other indemnification obligations have an indefinite term. The amount of the liability relating to all of these indemnification obligations included in other liabilities on the Company's unaudited condensed consolidated balance sheets as of December 30, 2016 and September 30, 2016 was $15.1 million and $15.7 million, respectively, of which $12.4 million and $12.9 million, respectively, related to environmental, health and safety matters. The value of the environmental, health and safety indemnity was measured based on the probability-weighted present value of the costs expected to be incurred to address environmental, health and safety claims made under the indemnity. The aggregate fair value of these indemnification obligations did not differ significantly from their aggregate carrying value at December 30, 2016 and September 30, 2016. As of December 30, 2016, the maximum future payments the Company could be required to make under these indemnification obligations were $71.0 million. The Company was required to pay $30.0 million into an escrow account as collateral to the purchaser, of which $19.0 million remained in other assets on the unaudited condensed consolidated balance sheets at both December 30, 2016 and September 30, 2016.

The Company has recorded liabilities for known indemnification obligations included as part of environmental liabilities, which are discussed in Note 16.

In addition, the Company is also liable for product performance; however, the Company believes, given the information currently available, that their ultimate resolutions will not have a material adverse effect on its financial condition, results of operations and cash flows.

The Company is required to provide the U.S. Nuclear Regulatory Commission financial assurance demonstrating its ability to fund the decommissioning of its Maryland Heights, Missouri radiopharmaceuticals production facility upon closure, though the Company does not intend to close this facility. The Company has provided this financial assurance in the form of surety bonds totaling $30.2 million. As of December 30, 2016, the Company had various other letters of credit, guarantees and surety bonds totaling $28.4 million.

In addition, the separation and distribution agreement entered into with Covidien plc ("Covidien"), as part of the Company's legal separation from Covidien, provides for cross-indemnities principally designed to place financial responsibility of the obligations and liabilities of the Company's business with the Company and financial responsibility for the obligations and liabilities of Covidien's remaining business with Covidien, among other indemnities.
