Revenues for the fourth quarter of 2018 were 8 percent higher compared to the third quarter of 2018, reflecting increased demand broadly across our products and end markets. Our overall gross margin was 61.0 percent for the fourth quarter of 2018 compared to 60.6 percent in the third quarter benefiting from strong execution across our product portfolio.

Investments in capital expenditures, net of amounts funded by partners, were $2.06 billion for the fourth quarter of 2018 and $8.20 billion for the full year of 2018, which resulted in adjusted free cash flows(3) of $3.09 billion for the fourth quarter of 2018 and $9.20 billion for the full year of 2018. We repurchased or converted $2.23 billion principal amount of our debt during the quarter and $6.96 billion for the full year of 2018, lowering our total carrying value of debt to $4.64 billion exiting the fiscal year. We ended the fourth quarter in a record net cash position of $2.72 billion with cash, marketable investments, and restricted cash of $7.36 billion.

1. In the fourth quarter of 2018, we prepaid or repurchased debt with an aggregate principal amount of $2.00 billion and recognized non-operating losses of $9 million. In addition, we settled convertible notes with an aggregate principal amount of $228 million for cash of $1.27 billion and recognized non-operating gains of $25 million. As of August 30, 2018, $35 million of aggregate principal amount of our convertible notes had converted but will not settle until the first quarter of 2019. As a result of the unsettled conversions, the carrying value of debt increased by $132 million as of August 30, 2018 and we recognized non-operating losses of $15 million in the fourth quarter of 2018. In the third quarter of 2018, we prepaid debt with an aggregate principal amount of $2.08 billion and recognized non-operating losses of $42 million. In addition, we repurchased or settled convertible notes with an aggregate principal amount of $228 million for cash of $1.11 billion and recognized non-operating losses of $32 million. In the second quarter of 2018, we settled convertible notes with an aggregate principal amount of $65 million for cash of $295 million. In the first quarter of 2018, we redeemed notes with an aggregate principal amount of $2.25 billion for cash of $2.42 billion and recognized non-operating losses of $190 million. During 2018, Intel Corporation provided non-interest bearing convertible debt financing of $1.01 billion to IM Flash Technologies, LLC (“IMFT”) pursuant to the terms of the IMFT joint venture agreement. 2. On December 22, 2017, the United States enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”) which lowers the U.S. corporate income tax rate from 35% to 21% and significantly affects how income from foreign operations is taxed in the United States. As a result of our fiscal year-end, our U.S. statutory federal rate was 25.7% for 2018 (based on the 35% corporate rate through December 31, 2017 and 21% from that date through the end of fiscal year 2018) and will be 21% for subsequent years. The Tax Act imposed a one-time transition tax in 2018 on the higher of accumulated foreign income, as determined as of November 2, 2017 or December 31, 2017 (the “Repatriation Tax”); provided a U.S. federal tax exemption on foreign earnings distributed to the United States; and, beginning in 2019, creates a new minimum tax on certain foreign earnings in excess of a deemed return on tangible assets (the “Foreign Minimum Tax”). The Tax Act allows us to elect to pay any Repatriation Tax due in eight annual interest-free payments in increasing amounts beginning in December 2018. The Securities and Exchange Commission Staff Accounting Bulletin No. 118 allows the use of provisional amounts (reasonable estimates) if our analyses of the impacts of the Tax Act has not been completed when our financial statements are issued. The provisional amounts below were revised during 2018 and represent reasonable estimates of the effects of the Tax Act for which the analysis is not yet complete. Our income tax (provision) benefit consisted of the following:

The tables above reconcile GAAP to non-GAAP results, diluted shares, and diluted earnings per share. The non-GAAP adjustments above may or may not be infrequent or nonrecurring in nature but are a result of periodic or non-core operating activities. We believe this non-GAAP information is helpful to understanding trends and in analyzing our operating results and earnings. We are providing this information to investors to assist in performing analysis of our operating results. When evaluating performance and making decisions on how to allocate our resources, management uses this non-GAAP information and believes investors should have access to similar data when making their investment decisions. We believe these non-GAAP financial measures increase transparency by providing investors with useful supplemental information about the financial performance of our business, enabling enhanced comparison of our operating results between periods and with peer companies. The presentation of these adjusted amounts vary from numbers presented in accordance with U.S. GAAP and therefore may not be comparable to amounts reported by other companies.

Our management excludes the following items in analyzing our operating results and understanding trends in our earnings:

-- Stock-based compensation; -- Flow-through of business acquisition-related inventory adjustments; -- Acquisition-related costs; -- Restructure and asset impairments; -- Amortization of debt discount and other costs, including the accretion of non-cash interest expense associated with our convertible debt and MMJ creditor debt; -- Gains and losses from debt repurchases and conversions; -- Gains and losses from changes in currency exchange rates; -- Gains and losses loss from business acquisition activities; -- Impact of the U.S. income tax reform for provisional estimate of Repatriation Tax, release of U.S. valuation allowance, and remeasurement of net deferred taxes reflecting the lower U.S. corporate tax rates: -- The estimated tax effects of above, including tax benefits from stock-based compensation, and non-cash changes in net deferred taxes; and -- Impairments of equity method investments.

Our outstanding capped call transactions are anti-dilutive in GAAP earnings per share but are expected to mitigate the dilutive effect of our convertible notes. In periods with non-GAAP income attributable to Micron, non-GAAP diluted shares include the impact of the capped calls, based on the average share price for the period the capped calls are outstanding. Non-GAAP diluted shares are also adjusted for the impact of additional shares resulting from the exclusion of stock-based compensation from non-GAAP income.
