Schedule Of Geographic Components Of Income Before Income Taxes And Equity Earnings Of Certain Unconsolidated Subsidiaries | The geographic components of Income Before Income Taxes and Equity Earnings of Certain Unconsolidated Subsidiaries at Sempra Energy Consolidated are as follows:

(Dollars in millions)
| Pretax book income
| Years ended December 31,
| 2016(1) |  | 2015 |  | 2014
U.S. | $ | 773 |  |  | $ | 1,189 |  |  | $ | 1,014 |

Total | $ | 1,830 |  |  | $ | 1,704 |  |  | $ | 1,524 |
(1) | U.S. pretax book income decreased in 2016 at the California Utilities primarily due to the reallocation of prior years’ income tax benefits generated from income tax repairs deductions to ratepayers pursuant to the 2016 GRC FD, as we discuss in Note 14; at Sempra LNG & Midstream for the loss on permanent release of pipeline capacity, as we discuss in Note 15; and the impairment charge related to the investment in Rockies Express, as we discuss in Note 3. Non-U.S. pretax book income increased in 2016 primarily due to the noncash gain associated with the remeasurement of our equity interest in GdC, as we discuss in Note 3.
Schedule Of Components Of Income Tax Expense | The components of income tax expense are as follows:
