Currently, GAAP requires the deferred taxes for each jurisdiction to be presented as a net current asset or liability and net noncurrent asset or liability. This requires a jurisdiction-by-jurisdiction analysis based on the classification of the assets and liabilities to which the underlying temporary differences relate, or, in the case of loss or credit carryforwards, based on the period in which the attribute is expected to be realized. Any valuation allowance is then required to be allocated on a pro rata basis, by jurisdiction, between current and noncurrent deferred tax assets. To simplify presentation, the new guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. As a result, each jurisdiction will now only have one net noncurrent deferred tax asset or liability. The guidance does not change the existing requirement that only permits offsetting within a jurisdiction, companies are still prohibited from offsetting deferred tax liabilities from one jurisdiction against deferred tax assets of another jurisdiction. The new guidance is effective in fiscal years beginning after December 15, 2016, including interim periods within those years. Early adoption is permitted as of the beginning of an interim or annual reporting period. The guidance may be applied either prospectively, for all deferred tax assets and liabilities, or retrospectively by reclassifying the comparative balance sheet. Teradyne will early adopt this ASU prospectively in January 2016. This ASU is expected to have no impact on Teradyne’s results of operations.</font></p> <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px; TEXT-INDENT: 4%"> <font style="FONT-FAMILY: Times New Roman" size="2">In September 2015, the FASB issued ASU 2015-16, <i>“Business Combinations (Topic 805)—Simplifying the Accounting for Measurement-Period Adjustments</i>.<i>”</i> ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustments are identified, including the cumulative effect of the change in provisional amount as if the accounting had been completed at the acquisition date. ASU 2015-16 is effective for reporting periods beginning after December 15, 2015 and is applied prospectively. Early adoption is permitted. Teradyne early adopted this ASU in 2015. Adoption of this ASU did not have a material impact on Teradyne’s financial position and results of operations.</font></p> <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px; TEXT-INDENT: 4%"> <font style="FONT-FAMILY: Times New Roman" size="2">On April 7, 2015, the FASB issued ASU 2015-03, <i>“Simplifying the Presentation of Debt Issuance Costs,”</i> which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation for debt discount. ASU 2015-03 does not specifically address requirements for the presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. On August 8, 2015, the FASB issued ASU 2015-15, <i>“Interest—Imputation of Interest (Subtopic 835-30)”</i> clarifying that debt issuance costs related to line-of-credit arrangements could be presented as an asset and amortized over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. For Teradyne, the standard is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those years. This ASU is expected to have no impact on Teradyne’s financial position and results of operations.</font></p> <p style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 12px; TEXT-INDENT: 4%"> <font style="FONT-FAMILY: Times New Roman" size="2">In May 2014, the FASB issued ASU 2014-09, <i>“Revenue from Contracts with Customers (Topic 606),”</i> which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to show the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled to in exchange for those goods or services. In August 2015, FASB issued ASU 2015-14, which deferred the effective date of the new revenue standard by one year. For Teradyne, the standard will be effective in the first quarter of 2018. Early adoption is permitted but not before the original effective date (that is, annual periods beginning after December 15, 2016). The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. Teradyne has not yet selected a transition method. Teradyne is currently evaluating the impact of this ASU on its financial position and results of operations.</font></p> </div>
