# 1. Basis of Presentation

The Consolidated Financial Statements reflect the consolidated operations of TE Connectivity Ltd. and its subsidiaries and have been prepared in United States (‘‘U.S.’’) dollars in accordance with accounting principles generally accepted in the U.S. (‘‘GAAP’’).

# Description of the Business

TE Connectivity Ltd. (‘‘TE Connectivity’’ or the ‘‘Company,’’ which may be referred to as ‘‘we,’’ ‘‘us,’’ or ‘‘our’’) is a global technology and manufacturing leader creating a safer, sustainable, productive, and connected future. For more than 75 years, our connectivity and sensor solutions, proven in the harshest environments, have enabled advancements in transportation, industrial applications, medical technology, energy, data communications, and the home.

We operate through three reportable segments:

• Transportation Solutions. The Transportation Solutions segment is a leader in connectivity and sensor technologies. Our products, which must withstand harsh conditions, are used in the automotive, commercial transportation, and sensors markets.

• Industrial Solutions. The Industrial Solutions segment is a leading supplier of products that connect and distribute power, data, and signals. Our products are used in the industrial equipment; aerospace, defense, oil, and gas; and energy markets.

• Communications Solutions. The Communications Solutions segment is a leading supplier of electronic components for the data and devices and the appliances markets. We are also a leader in developing, manufacturing, installing, and maintaining some of the world’s most advanced subsea fiber optic communications systems.

# Use of Estimates

The preparation of the Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Significant estimates in these Consolidated Financial Statements include restructuring and other charges, assets acquired and liabilities assumed in acquisitions, allowances for doubtful accounts receivable, estimates of future cash flows and discount rates associated with asset impairments, useful lives for depreciation and amortization, loss contingencies, net realizable value of inventories, estimated contract revenue and related costs, legal contingencies, tax reserves and deferred tax asset valuation allowances, and the determination of discount and other rate assumptions for pension benefit cost. Actual results could differ materially from these estimates.

# Fiscal Year

We have a 52- or 53-week fiscal year that ends on the last Friday of September. For fiscal years in which there are 53 weeks, the fourth quarter reporting period includes 14 weeks. Fiscal 2017, 2016, and 2015 ended on September 29, 2017, September 30, 2016, and September 25, 2015, respectively. Fiscal 2017 and 2015 were 52 weeks in length. Fiscal 2016 was a 53-week year.

# 2. Summary of Significant Accounting Policies

# Principles of Consolidation

We consolidate entities in which we own or control more than 50% of the voting shares or otherwise have the ability to control through similar rights. All intercompany transactions have been eliminated. The results of companies acquired or disposed of are included on the Consolidated Financial Statements from the effective date of acquisition or up to the date of disposal.

# Revenue Recognition

Our revenues are generated principally from the sale of our products. Revenue from the sale of products is recognized at the time title and the risks and rewards of ownership pass to the customer. This generally occurs when the products reach the shipping point, the sales price is fixed and determinable, and collection is reasonably assured.

Contract revenues for construction related projects, which are generated in the Communications Solutions segment, are recorded primarily using the percentage-of-completion method. Profits recognized on contracts in process are based upon estimated contract revenue and related cost to complete. Percentage-of-completion is measured based on the ratio of actual costs incurred to total estimated costs. Revisions in cost estimates as contracts progress have the effect of increasing or decreasing profits in the current period. Provisions for anticipated losses are made in the period in which they first become determinable. In addition, provisions for credit losses related to unbilled receivables on construction related projects are recorded as reductions of revenue in the period in which they first become determinable.

We generally warrant that our products will conform to our, or mutually agreed to, specifications and that our products will be free from material defects in materials and workmanship for a limited time. We limit our warranty to the replacement or repair of defective parts, or a refund or credit of the price of the defective product. We accept returned goods only when the customer makes a verified claim and we have authorized the return. Generally, a reserve for estimated returns is established at the time of sale based on historical return experience and is recorded as a reduction of sales.

Additionally, certain of our long-term contracts in the Communications Solutions segment have warranty obligations. Estimated warranty costs for each contract are determined based on the contract terms and technology-specific considerations. These costs are included in total estimated contract costs and are accrued over the construction period of the respective contracts under percentage-of-completion accounting.

We provide certain distributors with an inventory allowance for returns or scrap equal to a percentage of qualified purchases. A reserve for estimated returns and scrap allowances is established at the time of the sale based on an agreed-upon, fixed percentage of sales to distributors and is recorded as a reduction of sales.

Other allowances include customer quantity and price discrepancies. A reserve for other allowances is generally established at the time of sale based on historical experience and is recorded as a reduction of sales. We believe we can reasonably and reliably estimate the amounts of future allowances.
