Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation:

The accompanying Condensed Consolidated Financial Statements included herein have been prepared by Plexus Corp. and its subsidiaries (together “Plexus” or the “Company”) without audit and pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). The accompanying Condensed Consolidated Financial Statements reflect all adjustments, which include normal recurring adjustments necessary for the fair statement of the consolidated financial position of the Company as of March 30, 2019 and September 29, 2018, the results of operations and shareholders' equity for the three and six months ended March 30, 2019 and March 31, 2018, and the cash flows for the same six month periods.

The Company’s fiscal year ends on the Saturday closest to September 30. The Company uses a “4-4-5” weekly accounting system for the interim periods in each quarter. Each quarter, therefore, ends on a Saturday at the end of the 4-4-5 period. Periodically, an additional week must be added to the fiscal year to re-align with the Saturday closest to September 30. All fiscal quarters presented herein included 13 weeks.

Certain information and footnote disclosures, normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"), have been condensed or omitted pursuant to the SEC’s rules and regulations dealing with interim financial statements. However, the Company believes that the disclosures made in the Condensed Consolidated Financial Statements included herein are adequate to make the information presented not misleading. It is suggested that these Condensed Consolidated Financial Statements be read in conjunction with the Consolidated Financial Statements and notes thereto included in the Company’s 2018 Annual Report on Form 10-K.

Recently Adopted and Issued Accounting Pronouncements Not Yet Adopted

Recently Adopted Accounting Pronouncements:

In October 2016, the Financial Accounting Standards Board (the "FASB") issued ASU 2016-16 related to the income tax consequences of intra-entity transfers of assets other than inventory. The new standard eliminates the exception for an intra-entity transfer of an asset other than inventory and requires an entity to recognize the income tax consequences when the transfer occurs. The Company adopted this guidance under the modified retrospective approach during the first quarter of fiscal 2019. The Company recognized no net impact to its fiscal 2019 opening Retained Earnings balance upon adoption and does not anticipate any material impact to the Company's future Consolidated Financial Statements.

In August 2016, the FASB issued ASU 2016-15 related to the classification of certain cash receipts and cash payments, which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The new standard addresses certain issues where diversity in practice was identified. It also amends existing guidance, which is principles based and often requires judgment to determine the appropriate classification of cash flows as operating, investing or financing activities and clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The Company adopted this guidance during the first quarter of fiscal 2019 with no material impact to the Company's Condensed Statements of Cash Flows.

In May 2014, the FASB issued ASU 2014-09, which requires an entity to recognize revenue relating to contracts with customers that depicts the transfer of promised goods or services to customers in an amount reflecting the consideration to which the entity expects to be entitled in exchange for such goods or services ("Topic 606"). Topic 606 also requires disclosures enabling users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers and was effective for the Company beginning in the first quarter of fiscal year 2019.

On September 30, 2018, the Company adopted and applied Topic 606 to all contracts using the modified retrospective method of adoption. Upon adoption, the Company recognized an increase to its beginning Retained Earnings balance of $7.8 million. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. Refer to Note 13, "Revenue from Contracts with Customers," for further information.

Recently Issued Accounting Pronouncements Not Yet Adopted:

In February 2016, the FASB issued ASU 2016-02, which requires lessees to recognize most leases on their balance sheets but record expenses on their income statements in a manner similar to current accounting. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. The guidance is effective for the Company beginning in the first quarter of fiscal year 2020. Early adoption is permitted. The Company is currently in the process of assessing the impact of the adoption of the new standard on its Consolidated Financial Statements and plans to adopt the standard in the first quarter of fiscal year 2020.

In August 2017, the FASB issued ASU 2017-12 related to the accounting for hedging activities. The pronouncement expands and refines hedge accounting, aligns the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The guidance is effective for the Company beginning in the first quarter of fiscal year 2020. Early adoption is permitted. The Company is currently in the process of assessing the impact of the adoption of the new standard on its Consolidated Financial Statements and the timing of adoption.

The Company believes that no other recently issued accounting standards will have a material impact on its Consolidated Financial Statements, or apply to its operations.

Fair Value of Financial Instruments

Fair Value Measurements:

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (or exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses quoted market prices when available or discounted cash flows to calculate fair value. The accounting guidance establishes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. The input levels are:

Level 1:  Quoted (observable) market prices in active markets for identical assets or liabilities.

Level 2:  Inputs other than Level 1 that are observable, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3:  Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the asset or liability.
