Commitments & Contingencies

In the ordinary course of business, we enter into contractual agreements with third parties that include non-cancelable payment obligations, for which we are liable in future periods. These arrangements can include terms binding us to minimum payments and/or penalties if we terminate the agreement for any reason other than an event of default as described by the agreement. The following table presents a summary of our contractual obligations and commitments as of September 28, 2018 (in thousands):

Naming Rights. We are party to an agreement for naming rights and related benefits with respect to the Dolby Theatre in Hollywood, California, the location of the Academy Awards®. The term of the agreement is 20 years, over which we will make payments on a semi-annual basis until fiscal 2032. Our payment obligations are conditioned in part on the Academy Awards being held and broadcast from the Dolby Theatre.

Operating Leases. Operating lease payments represent our commitments for future minimum rent made under non-cancelable leases for office space, including those payable to our principal stockholder and portions attributable to the controlling interests in our wholly owned subsidiaries. The following table summarizes information about our total rental expenses under operating leases, including the portion of this total rent expense which is payable to our principal stockholder (in thousands):



	Fiscal Year Ended
	September 28, 2018		September 29, 2017		September 30, 2016
Total rent expense	$	17,161	$	15,091	$	13,288

Purchase Obligations. Purchase obligations primarily consist of our commitments made under agreements to purchase goods and services related to Dolby Cinema and for purposes that include IT and telecommunications, marketing and professional services, and manufacturing and other R&D activities.

Donation Commitments. Our donation commitments relate to non-cancelable obligations to the Museum of the Academy of Motion Picture Arts and Sciences in Los Angeles, California, and the Smithsonian Institution in Washington, DC. Our commitment to the Museum of the Academy of Motion Picture Arts and Sciences is for 15 years from its expected opening date in fiscal 2019, and the Smithsonian Institution is for the next 5 years. Both donation commitments consist of the installation of imaging and audio products in its theaters and providing maintenance services in exchange for various marketing, branding, and publicity benefits.

Indemnification Clauses. On a limited basis, our contractual agreements will contain a clause under which we agree to provide indemnification to the counterparty, most commonly to licensees in connection with licensing arrangements that include our IP. We have also entered into indemnification agreements with our officers, directors, and certain employees, and our certificate of incorporation and bylaws contain similar indemnification obligations. Additionally, and although not a contractual requirement, we have at times elected to defend our licensees from third party IP infringement claims. Since the terms and conditions of our contractual indemnification clauses do not explicitly specify our obligations, we are unable to reasonably estimate the maximum potential exposure for which we could be liable. Furthermore, we have not historically made any payments in connection with any such obligation and believe there to be a remote likelihood that any potential exposure in future periods would be of a material amount. As a result, no amounts have been accrued in our consolidated financial statements with respect to the contingent aspect of these indemnities.
