approximately $41.6 million was held outside the U. S.  in our foreign subsidiaries.
We have not repatriated nor do we currently have plans to repatriate these funds, but if we were to repatriate cash held outside of the U. S.  for domestic cash operations, we would be required to accrue and pay U. S.  income taxes to repatriate these funds less any previously paid foreign income taxes.
We consider the undistributed earnings of our foreign subsidiaries as of December 31, 2015 to be indefinitely reinvested, and, accordingly, no U. S.  income taxes have been provided thereon.
Our cash and cash equivalents and marketable securities are held for working capital purposes.
We plan to continue to invest for long-term growth.
We believe that our existing cash and cash equivalents together with cash flow from operations will be sufficient to meet our working capital requirements and our growth strategies for the foreseeable future.
Our future capital requirements will depend on many factors, including our growth rate, the timing and extent of our spending to support research and development activities, the timing and cost of establishing additional sales and marketing capabilities, the introduction of new and enhanced product and service offerings, our costs and access to outsourcing our manufacturing, our costs related to investing in or acquiring complementary or strategic businesses and technologies, the continued market acceptance of our products, and costs incurred related to outstanding litigation claims.
If we require or elect to seek additional capital through debt or equity financing in the future, we may not be able to raise capital on terms acceptable to us or at all.
If we are required and unable to raise additional capital when desired, our business, operating results and financial condition may be adversely affected.
Cash Flows
## Table 0 ##
Year Ended December 31,
## Table 1 ##
Cash Flows from Operating Activities Our primary source of cash from operating activities has been from cash collections from our customers.
We expect cash inflows from operating activities to be affected by increased sales and timing of collections.
Our primary uses of cash from operating activities have been for personnel costs, inventory purchases from our contract manufacturer, investment in research and development, and litigation expenses.
During the year ended December 31, 2015, cash provided by operating activities was $200.5 million, primarily from net income of $121.1 million, net non-cash charges of ($1.2) million, and a net increase in cash from changes in our operating assets and liabilities of $80.6 million.
The net increase in cash from changes in operating assets and liabilities was primarily due to an increase in deferred revenue of $90.3 million, largely related to short and long-term services contracts and product revenue deferrals related to contracts with acceptance terms.
In addition, we experienced an increase in cash of $32.0 million from income taxes payable and an increase in our accounts payable and accrued liabilities of $29.4 million due to the timing of payments.
These operating liability increases were offset by an increase in our accounts receivable of $47.3 million
As of December 31, 2015, the future minimum payments due under the lease financing obligation were as follows (in thousands):
## Table 2 ##
Upon completion of construction in 2013, we evaluated the de-recognition of the asset and liability under the sale-leaseback accounting guidance.
We concluded that we had forms of continued economic involvement in the facility, and therefore did not meet with the provisions for sale-leaseback accounting.
Therefore, the lease is accounted for as a financing obligation and lease payments will be attributed to (1) a reduction of the principal financing obligation; (2) imputed interest expense; and (3) land lease expense (which is considered an operating lease and a component of cost of goods sold and operating expenses) representing an imputed cost to lease the underlying land of the building.
In addition, the underlying building asset is depreciated over the building’s estimated useful life of 30 years.
At the conclusion of the initial lease term, we will de-recognize both the net book values of the asset and the remaining financing obligation.
Purchase Commitments We outsource most of our manufacturing and supply chain management operations to third-party contract manufacturers, who procure components and assemble products on our behalf based on our forecasts in order to reduce manufacturing lead times and ensure adequate component supply.
We issue purchase orders to our contract manufacturers for finished product and a significant portion of these orders consist of firm noncancelable commitments.
In addition, we purchase strategic component inventory from certain suppliers under purchase commitments that in some cases are non-cancelable, including integrated circuits, which are consigned to our contract manufacturers.
As of December 31, 2015, we had non-cancelable purchase commitments of $43.9 million to our contract manufacturers and suppliers.
We have provided restricted deposits to our third-party contract manufacturers and vendors to secure our obligations to purchase inventory.
We had $2.3 million in restricted deposits as of December 31, 2015 and December 31, 2014.
Restricted deposits are classified in other assets in our accompanying consolidated balance sheets.
Guarantees We have entered into agreements with some of our direct customers and channel partners that contain indemnification provisions relating to potential situations where claims could be alleged that our products infringe the intellectual property rights of a third party.
We have at our option and expense the ability to repair any infringement, replace product with a non-infringing equivalent-in-function product or refund our customers

Management’s Discussion and Analysis of Financial Condition and Results of Operations You should read the following discussion and analysis of our financial condition and results of operations together with the consolidated financial statements and related notes that are included elsewhere in this Annual Report on Form 10-K.
This discussion contains forward-looking statements based upon current plans, expectations and beliefs that involve risks and uncertainties.
Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors” and elsewhere in this Annual Report on Form 10-K.  Overview We are a leading supplier of cloud networking solutions that use software innovations to address the needs of large-scale internet companies, cloud service providers and next-generation data centers and campuses for enterprise support.
Our cloud networking solutions consist of our Extensible Operating System, or EOS, a set of network applications and our Ethernet switching and routing platforms.
Our cloud networking solutions deliver industry-leading performance, scalability, availability, programmability, automation and visibility.
At the core of our cloud networking platform is EOS, which was purpose-built to be fully programmable and highly modular.
The programmability of EOS has allowed us to create a set of software applications that address the requirements of cloud networking, including workflow automation, network visibility and analytics, and has also allowed us to rapidly integrate with a wide range of third-party applications for virtualization, management, automation, orchestration and network services.
We believe that cloud networks will continue to replace legacy network technologies, and that our cloud networking platform addresses the large and growing cloud networking segment of data center switching, which
