New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards In October 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-16 – Intra-Entity Transfers Other Than Inventory, which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This ASU will be effective for us in the first quarter of 2019 and requires modified retrospective adoption. We are evaluating the effects of our adoption of this ASU on our financial statements. In June 2016, the FASB issued ASU 2016-13 – Measurement of Credit Losses on Financial Instruments, which requires a financial asset (or a group of financial assets) measured on the basis of amortized cost to be presented at the net amount expected to be collected. This ASU requires that the income statement reflect the measurement of credit losses for newly recognized financial assets as well as the expected increases or decreases of expected credit losses that have taken place during the period. This ASU requires that credit losses of debt securities designated as available-for-sale be recorded through an allowance for credit losses and limits the credit loss to the amount by which fair value is below amortized cost. This ASU will be effective for us in the first quarter of 2021 with adoption permitted as early as the first quarter of 2020. This ASU requires modified retrospective adoption, with prospective adoption for debt securities for which an other-than-temporary impairment had been recognized before the effective date. We are evaluating the timing and effects of our adoption of this ASU on our financial statements. In February 2016, the FASB issued ASU 2016-02 – Leases, which amends a number of aspects of lease accounting, including requiring lessees to recognize operating leases with a term greater than one year on their balance sheet as a right-of- use asset and corresponding liability, measured at the present value of the lease payments. This ASU will be effective for us in the first quarter of 2020 with early adoption permitted and requires modified retrospective adoption. The adoption of this ASU will result in an increase in right-of-use assets and corresponding liabilities. We are evaluating the timing and other effects of our adoption of this ASU on our financial statements. In January 2016, the FASB issued ASU 2016-01 – Recognition and Measurement of Financial Assets and Financial Liabilities, which provides guidance for the recognition, measurement, presentation, and disclosure of financial assets and liabilities. This ASU will be effective for us in the first quarter of 2019 and requires modified retrospective adoption. Our assets and liabilities subject to this standard are not material. In May 2014, the FASB issued ASU 2014-09 – Revenue from Contracts with Customers, which supersedes nearly all existing revenue recognition guidance under generally accepted accounting principles in the United States. The core principal of this ASU, as amended, is that an entity should recognize revenue when it transfers 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. This ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. This ASU will be effective for us in the first quarter of 2019 and we expect to elect the modified retrospective adoption method. As a result of the adoption of this ASU, we expect to recognize revenue from sales of products to our distributors (which generally have agreements allowing rights of return or price protection) at the time control transfers to our distributors, which is generally earlier than recognizing revenue only upon resale by our distributors under existing revenue recognition guidance. Revenue recognized upon resale by our distributors under these arrangements was 17% and 19% of our consolidated revenue for the second quarter and first six months of 2018, respectively, and 20% and 22% of our consolidated revenue for the second quarter and first six months of 2017, respectively. On the date of initial application of this ASU, we will derecognize the deferred income on sales made to our distributors through a cumulative adjustment to retained earnings. We expect the revenue deferral, historically recognized in the following period, to be offset by the earlier recognition of revenue as described above as control of product transfers to our distributors. As a result of the adoption of this ASU, we expect to recognize interest expense from the financing component for contracts with advanced payments under which we transfer control of our products to our customers for periods extending beyond one year, although historically such arrangements would not have resulted in significant amounts of interest expense. As a result of the adoption of this ASU, we expect that revenue recognized under our current license agreements will not change materially.
