The consolidated condensed financial statements have been prepared by Cirrus Logic, Inc. (“Cirrus Logic,” “we,” “us,” “our,” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission (the “Commission”).  The accompanying unaudited consolidated condensed financial statements do not include complete footnotes and financial presentations.  As a result, these financial statements should be read along with the audited consolidated financial statements and notes thereto for the year ended March 25, 2017, included in our Annual Report on Form 10-K filed with the Commission on May 24, 2017.  In our opinion, the financial statements reflect all material adjustments, including normal recurring adjustments, necessary for a fair presentation of the financial position, operating results and cash flows for those periods presented.  The preparation of financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect reported assets, liabilities, revenues and expenses, as well as disclosure of contingent assets and liabilities.  Actual results could differ from those estimates and assumptions.  Moreover, the results of operations for the interim periods presented are not necessarily indicative of the results that may be expected for the entire year.  Additionally, prior period amounts have been adjusted to conform to current year presentation.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (ASC Topic 606).  The purpose of this ASU is to converge revenue recognition requirements per U.S. GAAP and International Financial Reporting Standards (“IFRS”).  The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date after public comment supported a proposal to delay the effective date of this ASU to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period.  The Company is currently in the process of reviewing our customers’ contracts in respect of performance obligation identification and satisfaction, pricing, warranties, and return rights, among other considerations. Though we have not completed the process, the Company currently expects no material modifications to its financial statements upon adoption of this ASU. The standard may be adopted by full retrospective method, which applies retrospectively to each prior period presented, or by modified retrospective method with the cumulative effect adjustment recognized in beginning retained earnings as of the date of adoption. We anticipate using the modified retrospective adoption method.
 
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The FASB issued this update to increase transparency and comparability by recognizing lease assets and lease liabilities on the balance sheet and disclosing key leasing arrangement details.  Lessees would recognize operating leases on the balance sheet under this ASU — with the future lease payments recognized as a liability, measured at present value, and the right-of-use asset recognized for the lease term. A single lease cost would be recognized over the lease term.  For terms less than twelve months, a lessee would be permitted to make an accounting policy election to recognize lease expense for such leases generally on a straight-line basis over the lease term.  This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  Early adoption is permitted.  The Company is currently evaluating the impact of this ASU.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.  This ASU requires credit losses on available-for-sale debt securities to be presented as an allowance rather than a write-down. Unlike current U.S. GAAP, the credit losses could be reversed with changes in estimates, and recognized in current year earnings.  This ASU is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods.  Early adoption is permitted for annual periods beginning after December 15, 2018, including interim periods.  The Company is currently evaluating the impact of the adoption of this ASU on our financial statements. 
    
In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.  This ASU relates to income tax consequences of non-inventory intercompany asset transfers.  This ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods.  Early adoption is permitted, as of the beginning of an annual reporting period.  The guidance requires companies to apply a modified retrospective approach with a cumulative catch-up adjustment to beginning retained earnings in the period of adoption.  The Company early adopted this ASU in the first quarter of fiscal year 2018 with a $0.7 million impact to beginning retained earnings. 

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business.  The update states that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business, and should be treated as an asset acquisition instead. This ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods.  Early adoption is permitted under specific circumstances, including in an interim period, with prospective application. The Company adopted this ASU and applied the related guidance to an asset acquisition in the first quarter of fiscal year 2018.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.  This ASU eliminates step two of the goodwill impairment test.  An impairment charge is to be recognized for the amount by which the current value exceeds the fair value. This ASU is effective for annual periods beginning after December 15, 2019, including interim periods.  Early adoption is permitted, for interim or annual goodwill impairment tests performed after January 1, 2017. An entity is required to disclose the nature of and reason for the change in accounting principle upon transition. That disclosure should be provided in the first annual period and in the interim period within the first annual period when the entity initially adopts the amendments in this update. The Company is currently evaluating the impact of this ASU, which will be applied prospectively.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU applies to any company that changes the terms or conditions of a share-based award, considered a modification. Modification accounting would be applied unless certain conditions were met related to the fair value of the award, the vesting conditions and the classification of the modified award. This ASU is effective for annual periods beginning after December 15, 2017, with early adoption permitted. The standard should be applied prospectively to an award modified on or after the adoption date. The Company is currently evaluating the financial statement impact of this ASU.

The Company typically invests in highly-rated securities with original maturities generally ranging from one to three years. The Company's specifically identified gross unrealized loss of $103 thousand related to securities with total amortized cost of approximately $78.2 million at September 23, 2017.  No securities have been in a continuous unrealized loss position for more than 12 months as of September 23, 2017. The Company may sell certain of its marketable securities prior to their stated maturities for strategic reasons including, but not limited to, anticipated or actual changes in credit rating and duration management.  When evaluating an investment for other-than-temporary impairment, the Company reviews factors including the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer, changes in market interest rates and whether it is more likely than not the Company will be required to sell the investment before recovery of the investment’s cost basis. As of September 23, 2017, the Company does not consider any of its investments to be other-than-temporarily impaired.

The Company’s specifically identified gross unrealized losses of $55 thousand related to securities with total amortized cost of approximately $99.9 million at March 25, 2017. Four securities had been in a continuous loss position for more than 12 months as of March 25, 2017 The gross unrealized loss on these securities was less than one percent of the position value.  The Company may sell certain of its marketable securities prior to their stated maturities for strategic reasons including, but not limited to, anticipated or actual changes in credit rating and duration management.  When evaluating an investment for other-than-temporary impairment, the Company reviews factors including the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer, changes in market interest rates and whether it is more likely than not the Company will be required to sell the investment before recovery of the investment’s cost basis. As of March 25, 2017, the Company did not consider any of its investments to be other-than-temporarily impaired.

Fair Value of Financial Instruments
Fair Value of Financial Instruments
Fair Value of Financial Instruments

The Company has determined that the only assets and liabilities in the Company’s financial statements that are required to be measured at fair value on a recurring basis are the Company’s cash equivalents, investment portfolio, pension plan assets / liabilities and contingent consideration.  The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement.  The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Level 1 - Quoted prices in active markets for identical assets or liabilities.
Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, 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 assets or liabilities.
Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The Company’s cash equivalents and investment portfolio assets consist of debt securities, money market funds, and commercial paper and are reflected on our consolidated condensed balance sheets under the headings cash and cash equivalents, marketable securities, and long-term marketable securities.  The Company determines the fair value of its investment portfolio assets by obtaining non-binding market prices from its third-party pricing providers on the last day of the quarter, whose sources may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value.

In connection with one of the Company’s prior acquisitions accounted for as a business combination, the Company reported contingent consideration based upon achievement of certain milestones.  This liability is classified as Level 3 and valued using a discounted cash flow model.  The assumptions used in preparing the discounted cash flow include discount rate estimates and cash flow amounts.  See additional details below. 

Prior to paying off the Company’s long-term revolving facility in the prior fiscal quarter, interest was applied at a base rate plus applicable margin or LIBOR plus applicable margin and the fair value of the revolving facility approximated carrying value.

As of September 23, 2017 and March 25, 2017, the Company classified all investment portfolio and pension plan assets and liabilities as Level 1 or Level 2 assets and liabilities.  The only Level 3 liability is the contingent consideration described above and below.  The Company has no Level 3 assets.  There were no transfers between Level 1, Level 2, or Level 3 measurements for the three months ending September 23, 2017

The valuation of contingent consideration was initially based on a weighted-average discounted cash flow model.  The fair value is reviewed and estimated on a quarterly basis based on the probability of achieving defined milestones and current interest rates.  Significant changes in any of the unobservable inputs used in the fair value measurement of contingent consideration could result in a significantly lower or higher fair value.  An increase or decrease in the probability of achieving certain milestones within the earn out period would be accompanied by a directionally similar change in the fair value of the recorded liability.  A change in discount rate would be accompanied by a directionally opposite change in fair value.  Changes in the fair value of the recorded liability are reported in research and development expense in the consolidated condensed statements of income.  In the first quarter of the current fiscal year, changes in the probability of achieving certain milestones associated with Tranche B of the earn out were determined following a review of product shipment forecasts within the earn out period.  The revised estimates reduced the fair value of the liability as of September 23, 2017 as shown in the table below.

Revolving Credit Facilities
Revolving Credit Facilities
Revolving Credit Facilities

On July 12, 2016, Cirrus Logic entered into an amended and restated credit agreement (the “Amended Credit Agreement”) with Wells Fargo Bank, National Association, as Administrative Agent, and the Lenders party thereto, for the purpose of refinancing an existing credit facility and providing ongoing working capital.  The Amended Credit Agreement provides for a $300 million senior secured revolving credit facility (the “Amended Facility”).  The Amended Facility matures on July 12, 2021.  The Amended Facility is required to be guaranteed by all of Cirrus Logic’s material domestic subsidiaries (the “Subsidiary Guarantors”).  The Amended Credit Facility is secured by substantially all of the assets of Cirrus Logic and any Subsidiary Guarantors, except for certain excluded assets.

Borrowings under the Amended Facility may, at our election, bear interest at either (a) a base rate plus the applicable margin (“Base Rate Loans”) or (b) a LIBOR rate plus the applicable margin (“LIBOR Rate Loans”).  The applicable margin ranges from 0% to 0.50% per annum for Base Rate Loans and 1.25% to 2.00% per annum for LIBOR Rate Loans based on the Leverage Ratio (as defined below).  A commitment fee accrues at a rate per annum ranging from 0.20% to 0.30% (based on the Leverage Ratio) on the average daily unused portion of the commitment of the lenders.  The Amended Credit Agreement contains certain financial covenants providing that (a) the ratio of consolidated funded indebtedness to consolidated EBITDA for the prior four fiscal quarters must not be greater than 3.00 to 1.00 (the “Leverage Ratio”) and (b) the ratio of consolidated EBITDA for the prior four consecutive fiscal quarters to consolidated fixed charges (including amounts paid in cash for consolidated interest expenses, capital expenditures, scheduled principal payments of indebtedness, and income taxes) for the prior four consecutive fiscal quarters must not be less than 1.25 to 1.00 as of the end of each fiscal quarter.  The Amended Credit Agreement also contains negative covenants limiting the Company’s or any Subsidiary’s ability to, among other things, incur debt, grant liens, make investments, effect certain fundamental changes, make certain asset dispositions, and make certain restricted payments. 
 
As of September 23, 2017, the Company had no amounts outstanding under the Amended Facility and was in compliance with all covenants under the Amended Credit Agreement.
Pension Plan
Pension Plan
Pension Plan

As a result of the fiscal year 2015 acquisition of Wolfson Microelectronics, the Company now fully funds a defined benefit pension scheme (the “Scheme”), formerly maintained by Wolfson, for some of the employees in the United Kingdom.  The participants in the Scheme no longer accrue benefits and therefore the Company will not be required to make contributions in respect of future accruals. 

The Company elected to make a contribution of £1.5 million based on the latest triennial actuarial valuation in the prior fiscal quarter. As of September 23, 2017, the Scheme is in a net funded position (included within “Other assets” in the consolidated condensed balance sheet).

Our income tax expense was $17.2 million and $16.6 million for the second quarter of fiscal year 2018 and 2017, respectively, resulting in effective tax rates of 19.0% and 16.2% for the second quarter of fiscal year 2018 and 2017, respectively.  Our income tax expense was $22.2 million and $20.2 million for the first six months of fiscal year 2018 and 2017, respectively, resulting in effective tax rates of 16.0% and 16.3% for the first six months of fiscal year 2018 and 2017, respectively.  Our effective tax rate for the second quarter and first six months of fiscal year 2018 was lower than the federal statutory rate primarily due to income earned in certain foreign jurisdictions taxed below the federal statutory rate, excess tax benefits from stock-based compensation, and the U.S. R&D tax credit. Our effective tax rate for the second quarter and first six months of fiscal year 2017 was below the federal statutory rate primarily due to income earned in certain foreign jurisdictions taxed below the federal statutory rate, excess tax benefits from stock-based compensation, and the U.S. R&D tax credit.

The Company records unrecognized tax benefits for the estimated risk associated with tax positions taken on tax returns.  At September 23, 2017, the Company had unrecognized tax benefits of $33.6 million, all of which would impact the effective tax rate if recognized.  The Company recorded a gross decrease of $2.3 million due to the lapse of the statute of limitations in the first quarter of fiscal year 2018 applicable to a tax deduction claimed on a prior year tax return, as well as gross increases to its current year unrecognized tax benefits of $2.2 million and $2.8 million for the first and second quarters of fiscal year 2018, respectively. The Company believes it is reasonably possible that the gross unrecognized tax benefits could decrease by approximately $1.1 million in the next 12 months due to the lapse of the statute of limitations applicable to a tax position taken on a prior year tax return. The Company’s total unrecognized tax benefits are classified as “Other long-term liabilities” in the consolidated condensed balance sheets.
 
The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes.  As of September 23, 2017, the balance of accrued interest and penalties, net of tax, was $0.5 million

The Company and its subsidiaries are subject to U.S. federal income tax as well as income tax in multiple state and foreign jurisdictions.  Fiscal years 2014 through 2017 remain open to examination by the major taxing jurisdictions to which the Company is subject, although carry forward attributes that were generated in tax years prior to fiscal year 2014 may be adjusted upon examination by the tax authorities if they have been, or will be, used in a future period.  The Company is not currently under an income tax audit in any major taxing jurisdiction.

Net Income Per Share
Net Income Per Share
Net Income Per Share

Basic net income per share is based on the weighted effect of common shares issued and outstanding and is calculated by dividing net income by the basic weighted average shares outstanding during the period.  Diluted net income per share is calculated by dividing net income by the weighted average number of common shares used in the basic net income per share calculation, plus the equivalent number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding.  These potentially dilutive items consist primarily of outstanding stock options and awards (including restricted stock units and market stock units).

The following table details the calculation of basic and diluted earnings per share for the three and six months ended September 23, 2017 and September 24, 2016 (in thousands, except per share amounts):

Legal Matters
Legal Matters
Legal Matters
From time to time, we are involved in legal proceedings concerning matters arising in connection with the conduct of our business activities.  We regularly evaluate the status of legal proceedings in which we are involved in order to assess whether a loss is probable or there is a reasonable possibility that a loss or additional loss may have been incurred, and to determine if accruals are appropriate.  We further evaluate each legal proceeding to assess whether an estimate of possible loss or range of loss can be made.    

Based on current knowledge, management does not believe that there are any pending matters that could potentially have a material adverse effect on our business, financial condition, results of operations or cash flows.  However, we are engaged in various legal actions in the normal course of business.  There can be no assurances in light of the inherent uncertainties involved in any potential legal proceedings, some of which are beyond our control, and an adverse outcome in any legal proceeding could be material to our results of operations or cash flows for any particular reporting period.

Segment Information

We determine our operating segments in accordance with FASB guidelines.  Our Chief Executive Officer (“CEO”) has been identified as the chief operating decision maker under these guidelines. 

The Company operates and tracks its results in one reportable segment, but reports revenue performance in two product lines, Portable Audio and Non-Portable Audio and Other.  Our CEO receives and uses enterprise-wide financial information to assess financial performance and allocate resources, rather than detailed information at a product line level.  Additionally, our product lines have similar characteristics and customers.  They share support functions such as sales, public relations, supply chain management, various research and development and engineering support, in addition to the general and administrative functions of human resources, legal, finance and information technology.  Therefore, there is no complete, discrete financial information maintained for these product lines.
Revenues from our product lines are as follows (in thousands):

Recently Issued Accounting Pronouncements (Policies)
Recently Issued Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (ASC Topic 606).  The purpose of this ASU is to converge revenue recognition requirements per U.S. GAAP and International Financial Reporting Standards (“IFRS”).  The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date after public comment supported a proposal to delay the effective date of this ASU to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period.  The Company is currently in the process of reviewing our customers’ contracts in respect of performance obligation identification and satisfaction, pricing, warranties, and return rights, among other considerations. Though we have not completed the process, the Company currently expects no material modifications to its financial statements upon adoption of this ASU. The standard may be adopted by full retrospective method, which applies retrospectively to each prior period presented, or by modified retrospective method with the cumulative effect adjustment recognized in beginning retained earnings as of the date of adoption. We anticipate using the modified retrospective adoption method.
 
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The FASB issued this update to increase transparency and comparability by recognizing lease assets and lease liabilities on the balance sheet and disclosing key leasing arrangement details.  Lessees would recognize operating leases on the balance sheet under this ASU — with the future lease payments recognized as a liability, measured at present value, and the right-of-use asset recognized for the lease term. A single lease cost would be recognized over the lease term.  For terms less than twelve months, a lessee would be permitted to make an accounting policy election to recognize lease expense for such leases generally on a straight-line basis over the lease term.  This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  Early adoption is permitted.  The Company is currently evaluating the impact of this ASU.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.  This ASU requires credit losses on available-for-sale debt securities to be presented as an allowance rather than a write-down. Unlike current U.S. GAAP, the credit losses could be reversed with changes in estimates, and recognized in current year earnings.  This ASU is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods.  Early adoption is permitted for annual periods beginning after December 15, 2018, including interim periods.  The Company is currently evaluating the impact of the adoption of this ASU on our financial statements. 
    
In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.  This ASU relates to income tax consequences of non-inventory intercompany asset transfers.  This ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods.  Early adoption is permitted, as of the beginning of an annual reporting period.  The guidance requires companies to apply a modified retrospective approach with a cumulative catch-up adjustment to beginning retained earnings in the period of adoption.  The Company early adopted this ASU in the first quarter of fiscal year 2018 with a $0.7 million impact to beginning retained earnings. 

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business.  The update states that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business, and should be treated as an asset acquisition instead. This ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods.  Early adoption is permitted under specific circumstances, including in an interim period, with prospective application. The Company adopted this ASU and applied the related guidance to an asset acquisition in the first quarter of fiscal year 2018.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.  This ASU eliminates step two of the goodwill impairment test.  An impairment charge is to be recognized for the amount by which the current value exceeds the fair value. This ASU is effective for annual periods beginning after December 15, 2019, including interim periods.  Early adoption is permitted, for interim or annual goodwill impairment tests performed after January 1, 2017. An entity is required to disclose the nature of and reason for the change in accounting principle upon transition. That disclosure should be provided in the first annual period and in the interim period within the first annual period when the entity initially adopts the amendments in this update. The Company is currently evaluating the impact of this ASU, which will be applied prospectively.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU applies to any company that changes the terms or conditions of a share-based award, considered a modification. Modification accounting would be applied unless certain conditions were met related to the fair value of the award, the vesting conditions and the classification of the modified award. This ASU is effective for annual periods beginning after December 15, 2017, with early adoption permitted. The standard should be applied prospectively to an award modified on or after the adoption date. The Company is currently evaluating the financial statement impact of this ASU.
