Concentration of Credit Risk Credit risk represents the accounting loss that would be recognized at the reporting date if counterparties failed to perform as contracted.
The company believes the likelihood of incurring material losses due to concentration of credit risk is remote.
The principal financial instruments subject to credit risk are as follows: Cash and Cash Equivalents - The company maintains cash deposits with major banks, which from time to time may exceed insured limits.
The possibility of loss related to financial condition of major banks has been deemed minimal.
Additionally, the company’s investment policy limits exposure to concentrations of credit risk and changes in market conditions.
Accounts Receivable - A large number of customers in diverse industries and geographies, as well as the practice of establishing reasonable credit lines, limits credit risk.
Based on historical trends and experiences, the allowance for doubtful accounts is adequate to cover potential credit risk losses.
Foreign Currency and Interest Rate Contracts and Derivatives - Exposure to credit risk is limited by internal policies and active monitoring of counterparty risks.
In addition, the company uses a diversified group of major international banks and financial institutions as counterparties.
The company does not anticipate nonperformance by any of these counterparties.
Cash and Cash Equivalents Cash equivalents include highly-liquid investments with a maturity of three months or less when purchased.
Accounts Receivable and Allowance For Doubtful Accounts Accounts receivable are carried at their face amounts less an allowance for doubtful accounts.
Accounts receivable are recorded at the invoiced amount and generally do not bear interest.
The company estimates the balance of allowance for doubtful accounts by analyzing accounts receivable balances by age and applying historical write-off and collection trend rates.
The company’s estimates include separately providing for customer balances based on specific circumstances and credit conditions, and when it is deemed probable that the balance is uncollectible.
Account balances are charged off against the allowance when it is determined the receivable will not be recovered.
The company’s allowance for doubtful accounts balance also includes an allowance for the expected return of products shipped and credits related to pricing or quantities shipped of $15 million as of December 31, 2015 and 2014 and $14 million as of December 31, 2013.
Returns and credit activity is recorded directly to sales.
The following table summarizes the activity in the allowance for doubtful accounts:
## Table 0 ##
(a) Other amounts are primarily the effects of changes in currency translations and the impact of allowance for returns and credits.
Inventory Valuations Inventories are valued at the lower of cost or market.
Certain U. S.  inventory costs are determined on a last-in, first-out (LIFO) basis.
LIFO inventories represented 39% and 37% of consolidated inventories as of December 31, 2015 and 2014, respectively.
LIFO inventories include certain legacy Nalco U. S.  inventory acquired at fair value as part of the Nalco merger.
All other inventory costs are determined using either the average cost or first-in, first-out (FIFO) methods.
Inventory values at FIFO, as shown in Note 5, approximate replacement cost.
During the fourth quarter of 2015, the company improved estimates related to its inventory reserves and product costing, resulting in a net pre-tax charge of approximately $6 million.
Separately, the actions resulted in charge of $20.6 million related to inventory reserve calculations, partially offset by a gain of $14.5 million related to the capitalization of certain cost components into inventory.
Both of these items are reflected in Note 3.
cash flows.
The Company adopted the disclosure requirements as of January 1, 2009 on a prospective basis; accordingly, disclosures related to income and other comprehensive income (OCI) for prior periods have not been presented.
The adoption had no impact on our consolidated financial statements, besides the additional disclosures.
The Company is exposed to global market risks, including the effect of changes in interest rates and foreign currency fluctuations.
The Company uses foreign currency denominated debt and derivative instruments to mitigate the impact of these changes.
The Company does not use derivatives with a level of complexity or with a risk higher than the exposures to be hedged and does not hold or issue derivatives for trading purposes.
The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking hedging transactions.
The Company’s derivatives that are designated as hedging instruments consist mainly of interest rate exchange agreements, forward foreign currency exchange agreements and foreign currency options.
Interest rate exchange agreements are entered into to manage the interest rate risk associated with the Company’s fixed and floating-rate borrowings.
Forward foreign currency exchange agreements and foreign currency options are entered into to mitigate the risk that forecasted foreign currency cash flows (such as royalties denominated in foreign currencies) will be adversely affected by changes in foreign currency exchange rates.
Certain foreign currency denominated debt is used, in part, to protect the value of the Company’s investments in certain foreign subsidiaries and affiliates from changes in foreign currency exchange rates.
The Company also enters into certain derivatives that are not designated as hedging instruments.
The Company has entered into derivative contracts to hedge market-driven changes in certain of its supplemental benefit plan liabilities.
Changes in the fair value of these derivatives are recorded in selling, general & administrative expenses.
In addition, the Company uses forward foreign currency exchange agreements and foreign currency exchange agreements to mitigate the change in fair value of certain foreign denominated assets and liabilities.
Since these derivatives are not designated as hedging instruments, the changes in the fair value of these hedges are recognized immediately in nonoperating (income) expense together with the translation gain or loss from the hedged balance sheet position.
A portion of the Company’s foreign currency options (more fully described in the Cash Flow Hedging Strategy section) are undesignated as hedging instruments as the underlying foreign currency royalties are earned.
All derivative instruments designated as hedging instruments are classified as fair value, cash flow or net investment hedges.
All derivatives (including those not designated as hedging instruments) are recognized on the Consolidated balance sheet at fair value and classified based on the instruments’ maturity date.
Changes in the fair value measurements of the derivative instruments are reflected as adjustments to OCI and/or current earnings.
The following table presents the fair values of derivative instruments included on the Consolidated balance sheet:
## Table 1 ##
(1) The fair value of derivatives is presented on a gross basis.
Accordingly, the 2009 total asset and liability fair values do not agree with the values provided in the Fair Value Measurements note, because that disclosure reflects netting adjustments of $2.4 million.
Notes to Consolidated Financial Statements $(0.2) million, $(2.5) million and $2.1 million, respectively, of interest and penalties related to uncertain tax positions.
Accrued interest and penalties related to unrecognized tax benefits totaled $4.4 million, $4.6 million and $7.1 million as of March 30, 2019, March 31, 2018, and April 1, 2017, respectively.
The unrecognized tax benefits of $103.2 million and accrued interest and penalties of $4.4 million at the end of fiscal 2019 are recorded on the Consolidated Balance Sheet as a $14.8 million other long-term liability, with the balance reducing the carrying value of the gross deferred tax assets.
Within the next 12 months, the Company believes it is reasonably possible that only a minimal amount of gross unrecognized tax benefits will be reduced for tax positions taken in prior years, which will be with respect to uncertainty on the timing of the tax deductions.
Income taxes payable of $41.6 million and $60.0 million as of March 30, 2019 and March 31, 2018, respectively, are included in “Other current liabilities” in the Consolidated Balance Sheets.
Income taxes receivable of $6.2 million as of March 30, 2019 is included in “Other current assets” in the Consolidated Balance Sheets.
Long term income taxes payable of $5.7 million as of March 30, 2019, which relates to the Transitional Repatriation Tax which the Company has elected to pay over eight years, is included in “Other long-term liabilities” in the Consolidated Balance Sheets.
Qorvo’s fiscal 2016 U. S.  federal and state tax returns and subsequent tax years remain open for examination.
Tax attributes (including net operating loss and credit carryovers) arising in earlier fiscal years remain open to adjustment.
The Internal Revenue Service concluded its examination of the federal tax return for the short period ended January 1, 2015 for RFMD during fiscal 2019 with minimal adjustments.
The Inland Revenue Authority of Singapore similarly concluded its examination of the Singapore tax returns during fiscal 2019 for calendar years 2012 through fiscal 2015, resulting in a settlement of approximately $3.3 million which had previously been substantially accrued as an unrecognized tax benefit.
All years subsequent to fiscal 2015 remain open for examination by the Inland Revenue Authority of Singapore.
An examination by taxing authorities of the Company’s China subsidiary in Beijing of its calendar year 2013 through 2015 tax returns was completed in fiscal 2018 with minimal adjustments, and returns for subsequent tax years remain open for examination, as do all returns for the China subsidiary in Dezhou.
An examination by the
