Under existing guidance, operating leases are not recorded as lease assets and lease liabilities on the balance sheet. The update will be effective for us beginning in our first quarter of fiscal year 2020, with early adoption permitted. We are currently evaluating the impact of the adoption of this accounting guidance on our consolidated financial statements. However, we expect the adoption of this accounting guidance to result in an increase in lease assets and a corresponding increase in lease liabilities on our Consolidated Balance Sheets. The FASB issued an accounting standards update that creates a single source of revenue guidance under U.S. GAAP for all companies, in all industries, effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. We expect to adopt this guidance beginning in our first quarter of fiscal year 2019 using the modified retrospective approach. While we are still finalizing our analysis to quantify the adoption impact of the provisions of the new standard, we do not expect it to have a material impact on our consolidated financial statements.

Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Securities and Exchange Commission, or SEC, Regulation S-X. The January 29, 2017 consolidated balance sheet was derived from our audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended January 29, 2017, as filed with the SEC, but does not include all disclosures required by U.S. GAAP. In the opinion of management, all adjustments, consisting only of normal recurring adjustments except as otherwise noted, considered necessary for a fair statement of results of operations and financial position have been included. The results for the interim periods presented are not necessarily indicative of the results expected for any future period.

Fiscal Year

We operate on a 52- or 53-week year, ending on the last Sunday in January. Fiscal years 2018 and 2017 are both 52-week years. The first quarter of fiscal years 2018 and 2017 were both 13-week quarters.

Reclassifications

Certain prior fiscal year balances have been reclassified to conform to the current fiscal year presentation.

Principles of Consolidation

Our condensed consolidated financial statements include the accounts of NVIDIA Corporation and our wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. On an on-going basis, we evaluate our estimates, including those related to revenue recognition, cash equivalents and marketable securities, accounts receivable, inventories, income taxes, goodwill, stock-based compensation, litigation, investigation and settlement costs, restructuring and other charges, and other contingencies. These estimates are based on historical facts and various other assumptions that we believe are reasonable.

Adoption of New and Recently Issued Accounting Pronouncements

Recently Adopted Accounting Pronouncement

In October 2016, the Financial Accounting Standards Board, or FASB, issued an accounting standards update which requires the recognition of income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. We elected to early adopt this new guidance in the first quarter of fiscal year 2018, which required us to reflect any adjustments as of January 30, 2017. Upon adoption of this guidance, we recorded a cumulative-effect adjustment as of the first day of fiscal year 2018 to decrease retained earnings by $28 million, with a corresponding decrease to prepaid taxes that had not been previously recognized in income tax expense.

Recent Accounting Pronouncements Not Yet Adopted

In February 2016, the FASB issued an accounting standards update regarding the accounting for leases by which we will begin recognizing lease assets and liabilities on the balance sheet for leases with a lease term of more than 12 months. The update will require additional disclosures regarding key information about leasing arrangements. Under existing guidance, operating leases are not recorded as lease assets and lease liabilities on the balance sheet. The update will be effective for us beginning in our first quarter of fiscal year 2020, with early adoption permitted. We are currently evaluating the impact of the adoption of this accounting guidance on our consolidated financial statements. However, we expect the adoption of this accounting guidance to result in an increase in lease assets and a corresponding increase in lease liabilities on our Consolidated Balance Sheets.

The FASB issued an accounting standards update that creates a single source of revenue guidance under U.S. GAAP for all companies, in all industries, effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. We expect to adopt this guidance beginning in our first quarter of fiscal year 2019 using the modified retrospective approach. While we are still finalizing our analysis to quantify the adoption impact of the provisions of the new standard, we do not expect it to have a material impact on our consolidated financial statements.
