| Nonrecurring Fair Value Measurements |
The following table summarizes significant inputs impacting our non-recurring fair value measures: | | | | | | | | | | | | | | | | | | NON-RECURRING FAIR VALUE MEASURES – SEMPRA ENERGY CONSOLIDATED | | | | | | Estimated fair value (in millions) | | Valuation technique | | Fair value hierarchy | | % of fair value measurement | | Inputs used to
develop
measurement | | Range of
inputs | | Certain of our U.S. wind equity method investments | $ | 145 |
| | (1) | | Discounted cash flows | | Level 3 | | 100% | | Contracted and observable merchant prices per MWh | | $29 - $92 | (2) | | | | | | | | | | | | | Discount rate | | 8% - 10% | (3) | Non-utility natural gas storage assets | $ | 190 |
| | (4) | | Discounted cash flows | | Level 3 | | 100% | | Storage rates
per Dth/month | | $0.06 - $0.22 | (2) | | | | | | | | | | | | | Discount rate | | 10% | (3) |
| | (1) | At measurement date of June 25, 2018. At June 30, 2018, these U.S. wind equity method investments have a carrying value of $141 million, reflecting subsequent business activity. |
| | (2) | Generally, significant increases (decreases) in this input in isolation would result in a significantly higher (lower) fair value measurement. |
| | (3) | An increase in the discount rate would result in a decrease in fair value. |
(4) At measurement date of June 25, 2018. At June 30, 2018, Mississippi Hub and Bay Gas are classified as held for sale and have a net carrying value of $138 million, reflecting subsequent business activity and estimated costs to sell, as we discuss in Note 5. Our other U.S. midstream assets that were measured at fair value, including LA Storage, continue to be classified as property, plant and equipment and have a carrying value of $37 million at June 30, 2018.
