to 150 days. The Company also obtains individual components for its products from a wide variety of individual suppliers. Consistent with industry practice, the Company acquires components through a combination of purchase orders, supplier contracts, and open orders based on projected demand information. Where appropriate, the purchases are applied to inventory component prepayments that are outstanding with the respective supplier. As of September 26, 2015, the Company had outstanding off-balance sheet third-party manufacturing commitments and component purchase commitments of $29.5 billion. 

Other Obligations 

The Company’s other off-balance sheet obligations were comprised of commitments to acquire capital assets, including product tooling and manufacturing process equipment, and commitments related to inventory prepayments, advertising, licensing, R&D, internet and telecommunications services, energy and other obligations. 

The Company’s other non-current liabilities in the Consolidated Balance Sheets consist primarily of deferred tax liabilities, gross unrecognized tax benefits and the related gross interest and penalties. As of September 26, 2015, the Company had non-current deferred tax liabilities of $24.1 billion. Additionally, as of September 26, 2015, the Company had gross unrecognized tax benefits of $6.9 billion and an additional $1.3 billion for gross interest and penalties classified as non-current liabilities. At this time, the Company is unable to make a reasonably reliable estimate of the timing of payments in individual years in connection with these tax liabilities; therefore, such amounts are not included in the above contractual obligation table. 

Indemnification 

The Company generally does not indemnify end-users of its operating system and application software against legal claims that the software infringes third-party intellectual property rights. Other agreements entered into by the Company sometimes include indemnification provisions under which the Company could be subject to costs and/or damages in the event of an infringement claim against the Company or an indemnified third-party. In the opinion of management, there was not at least a reasonable possibility the Company may have incurred a material loss with respect to indemnification of end-users of its operating system or application software for infringement of third-party intellectual property rights. The Company did not record a liability for infringement costs related to indemnification as of September 26, 2015 or September 27, 2014. 

In September 2015, the Company introduced the iPhone Upgrade Program, which is available to customers who purchase an iPhone 6s and 6s Plus in one of its U.S. physical retail stores and activate the purchased iPhone with one of the four national carriers. The iPhone Upgrade Program provides customers the right to trade in that iPhone for a new iPhone, provided certain conditions are met. One of the conditions of this program requires the customer to finance the initial purchase price of the iPhone with a third-party lender. Upon exercise of the trade-in right and purchase of a new iPhone, the Company satisfies the
