Organization Consolidation And Presentation Of Financial Statements [Abstract]

Liquidity

The Company has financed its operations and capital investments through sales of common stock, finance leases, bank lines of credit and cash flows from operations. As of September 29, 2019, the Company's principal sources of liquidity consisted of cash and cash equivalents and restricted cash of $24.8 million, including $15.0 million drawn down from its revolving line of credit, or Revolving Facility with Heritage Bank of Commerce, or Heritage Bank. On November 6, 2019 the Company entered into a First Amendment to the Revolving Facility with Heritage Bank to extend the maturity date for one year through September 28, 2021. Under this amendment the Revolving Facility advances shall bear interest, on the outstanding daily balance thereof, at a rate per annum equal to the greater of (i) one half of one percentage point (0.50%) above the Prime Rate, or (ii) five and one half of one percentage points (5.50%).

On June 21, 2019, the Company closed its underwritten public offering of 18.4 million shares of common stock, $0.001 par value per share at a price of $0.50 per share, which included 2.4 million shares issued pursuant to the underwriters’ full exercise of their over-allotment option. The Company received net proceeds of approximately $8.0 million, after deducting underwriting commissions and other offering-related expenses.

Various factors can affect the Company’s liquidity, including, among others: the level of revenue and gross profit as a result of the cyclicality of the semiconductor industry; the conversion of design opportunities into revenue; market acceptance of existing and new products including solutions based on its ArcticLink^®, PolarPro^® platforms, eFPGA, EOS S3 SoC, Quick AI solution, SensiML software and Freedom Aware SoC Templates; fluctuations in revenue as a result of product end-of-life; fluctuations in revenue as a result of the stage in the product life cycle of its customers’ products; costs of securing access to and availability of adequate manufacturing capacity; levels of inventories; wafer purchase commitments; customer credit terms; the amount and timing of research and development expenditures; the timing of new product introductions; production volumes; product quality; sales and marketing efforts; the value and liquidity of its investment portfolio; changes in operating assets and liabilities; the ability to obtain or renew debt financing and to remain in compliance with the terms of existing credit facilities; the ability to raise funds from the sale of equity in the Company; the ability to capitalize on synergies with our newly acquired subsidiary SensiML; the issuance and exercise of stock options and participation in the Company’s employee stock purchase plan; and other factors related to the uncertainties of the industry and global economics.

Over the longer term, the Company anticipates that sales generated from its new product offerings, existing cash and cash equivalents, together with financial resources from its Revolving Facility with the Heritage Bank, assuming renewal of the Revolving Facility or the Company entering into a new debt agreement with an alternative lender prior to the expiration of the revolving line of credit in September 2021, and its ability to raise additional capital in the public capital markets will be sufficient to satisfy its operations and capital expenditures. However, the Company cannot provide any assurance that it will be able to raise additional capital, if required, or that such capital will be available on terms acceptable to the Company. The inability of the Company to generate sufficient sales from its new product offerings and/or raise additional capital if needed could have a material adverse effect on the Company’s operations and financial condition, including its ability to maintain compliance with its lender’s financial covenants.

Foreign Currency

The functional currency of the Company's non-U.S. operations is the U.S. dollar. Accordingly, all monetary assets and liabilities of these foreign operations are translated into U.S. dollars at current period-end exchange rates and non-monetary assets and related elements of expense are translated using historical exchange rates. Income and expense elements are translated to U.S. dollars using the average exchange rates in effect during the period. Gains and losses from the foreign currency transactions of these subsidiaries are recorded as interest income and other expense, net in the unaudited condensed consolidated statements of operations.

Concentration of Risk

The Company's accounts receivable are denominated in U.S. dollars and are derived primarily from sales to customers located in North America, Asia Pacific, and Europe. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. See Note 14 for information regarding concentrations associated with accounts receivable.

Leases

The Company adopted Accounting Standards Update, or ASU, No. 2016-02, Leases (Topic 842) and related ASUs, which provide supplementary guidance and clarifications on December 31, 2018, utilizing the modified retrospective transition method through a cumulative-effect adjustment at the beginning of the first quarter of 2019. Additionally, the Company elected the practical expedient approach and did not reassess whether any contracts that existed prior to adoption have or contain leases or the classification of our existing leases.

Under Topic 842, all significant lease arrangements are generally recognized at lease commencement. Operating lease right-of-use, or ROU, assets and lease liabilities are recognized at the commencement date. A ROU asset and corresponding lease liability is not recorded for leases with an initial term of 12 months or less (short term leases) and the Company recognizes lease expense for these leases as incurred over the lease term.

ROU assets represent the Company’s right to use an underlying asset during the reasonably certain lease terms and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company primarily uses its incremental borrowing rate, based on the information available at commencement date, in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments related to initial direct cost and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately.

In accordance with ASU No. 2016-02, the Company recognized right-of-use assets of approximately $975,000 and lease liabilities of approximately $939,000 on the Company’s Consolidated Balance Sheet as of March 31, 2019, with no material impact to its Consolidated Statements of operations. As of September 29, 2019, the Company’s right-of-use assets was approximately $2.2 million and lease liability was approximately $2.1 million as presented on the Company’s Consolidated Balance Sheet. See Note 8 to the Unaudited Consolidated Financial Statements for more details.

Goodwill and Intangible Assets

Goodwill represents the excess fair value of consideration transferred over the fair value of net assets acquired in business combinations. The carrying value of goodwill and indefinite lived intangible assets are not amortized, but are annually tested for impairment and more often if there is an indicator of impairment.

Intangible assets with finite useful lives are amortized on a straight-line basis over the periods benefited. The Company reviews the recoverability of its long-lived assets when events or changes in circumstances occur that indicate that the carrying value of the asset or asset group may not be recoverable. The assessment of possible impairment is based on the Company's ability to recover the carrying value of the asset or asset group from the expected future pre-tax cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset, an impairment loss is recognized for the difference between estimated fair value and carrying value. The measurement of impairment requires management to estimate future cash flows and the fair value of long-lived assets.

New Accounting Pronouncements

Recently adopted accounting pronouncements:

In January 2017, the FASB issued Accounting Standards Update ASU No. 2017-04, Simplifying the Test for Goodwill Impairment, which simplifies the subsequent measurement of goodwill. Goodwill impairment will equal the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Furthermore, the ASU eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform step 2 of the goodwill impairment test. The guidance will be applied prospectively, and is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for any impairment tests performed on testing dates after January 1, 2017. The Company has elected to early adopt this guidance effective December 31, 2018 for goodwill impairment test, which will be performed annually on December 1^st . The adoption of this guidance did not have a material impact on our consolidated financial statements.

In February 2018, FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income. The new standard provides companies with an option to reclassify stranded tax effects resulting from enactment of the Tax Cuts and Jobs Act, or TCJA, from accumulated other comprehensive income to retained earnings. The guidance will be effective for the Company beginning in the first quarter of 2019 with early adoption permitted, and would be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the tax rate as a result of TCJA is recognized. The Company adopted this ASU on December 31, 2018 with no material impact on its results of operations, financial position and cash flows.

In March 2018, FASB issued ASU No. 2018-05, Income Taxes (Topic 740). The new standard allows to insert the SEC’s interpretive guidance from Staff Accounting Bulletin, or SAB, No.118, into the income tax accounting codification under U.S. GAAP. The ASU permits companies to use provisional amounts for certain income tax effects of the Tax Act during a one-year measurement period. The provisional accounting impacts for the Company may change in future reporting periods until the accounting analysis is finalized, which will occur no later than the first quarter of fiscal 2019. The Company completed its SAB No.118 analysis with no material impact to the consolidated financial statements.

In June 2018, the FASB issued ASU No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. Currently, share-based payments to nonemployees are accounted for under Subtopic 505-50, which significantly differs from the guidance for share-based payments to employees under Topic 718. This ASU supersedes Subtopic 505-50 by expanding the scope of Topic 718 to include nonemployee awards and generally aligning the accounting for nonemployee awards with the accounting for employee awards. The effective date for public companies is for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. For all other entities, the effective date is fiscal years beginning after December 15, 2019. The Company adopted this ASU on December 31, 2018 with no material impact on its results of operations, financial position and cash flows.

Recently issued accounting pronouncements not yet adopted:

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This new standard modifies certain disclosure requirements on fair value measurements. The effective date for all entities is for fiscal years beginning after December 15, 2019. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementations Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. Under the new standard, implementations costs related to a cloud computing arrangement will be deferred or expensed as incurred, in accordance with the existing internal-use software guidance for similar costs. The new standard also prescribes the balance sheet, income statement and cash flow classification of the capitalized implementation costs and related amortizations expenses. The effective date for public companies is for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. For all other entities, the effective date is fiscal years beginning after December 15, 2021. The amendments may be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently evaluating the impact of our pending adoption of the new standard on the consolidated financial statements.
