In the second quarter of 2018, we settled convertible notes with aggregate principal amount of $65 million for cash of $295 million. Additionally, holders converted $71 million of aggregate principal amount of our convertible notes in the second quarter of 2018, which resulted in an increase to the carrying value of $238 million. As a result of the conversions, we recognized non-operating losses of $23 million in the second quarter of 2018. We will settle the conversions entirely in cash in the third quarter of 2018. 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.
(2) On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act") that 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 will be 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 21% for subsequent years. The Tax Act imposes a one-time transition tax in 2018 on the higher of our accumulated foreign income, as determined as of November 2, 2017 or December 31, 2017 (the "Repatriation Tax"); provides 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. In connection with the provisions of the Tax Act, we are continuing to evaluate whether to account for the Foreign Minimum Tax provisions that begin for us in 2019 as a period cost or in our measurement of deferred taxes.
The Securities and Exchange Commission's 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 for the second quarter of fiscal year 2018 are issued. Provisional amounts may be adjusted during a one-year measurement period as accounting for the income tax effects of the Tax Act are completed or as estimates are revised. Our income tax (provision) benefit consisted of the following:
