Schedule of Regulatory Assets and Liabilities Table [Table Text Block]

The following table summarizes our regulatory asset and liability balances as of December 31, 2018 and 2017 (in millions):



	December 31,
	2018		2017
Current regulatory assets	$	66	$	60
Non-current regulatory assets	245		288
Total regulatory assets(a)	$	311	$	348

Current regulatory liabilities	$	29	$	107
Non-current regulatory liabilities	206		236
Total regulatory liabilities(b)	$	235	$	343

_______

(a)

Regulatory assets as of December 31, 2018 include (i) $176 million of unamortized losses on disposal of assets; (ii) $53 million income tax gross up on equity AFUDC; and (iii) $82 million of other assets including amounts related to fuel tracker arrangements. Approximately $98 million of the regulatory assets, with a weighted average remaining recovery period of 23 years, are recoverable without earning a return, including the income tax gross up on equity AFUDC for which there is an offsetting deferred income tax balance for FERC rate base purposes; therefore, it does not earn a return.

(b)

Regulatory liabilities as of December 31, 2018 are comprised of customer prepayments to be credited to shippers or other over-collections that are expected to be returned to shippers or netted against under-collections over time. Approximately $136 million of the $206 million classified as non-current is expected to be credited to shippers over a remaining weighted average period of 18 years, while the remaining $70 million is not subject to a defined period.

Schedule of Antidilutive Securities Excluded from Computation of Earnings Per Share

The following maximum number of potential common stock equivalents are antidilutive and, accordingly, are excluded from the determination of diluted earnings per share (in millions on a weighted average basis):



	Year Ended December 31,
	2018	2017	2016
Unvested restricted stock awards	12	10	8
Warrants to purchase our Class P shares(a)		116	293

Mandatory convertible preferred stock(b)	48	58	58

_______


(a)	On May 25, 2017, approximately 293 million of unexercised warrants expired without the issuance of Class P common stock. Prior to expiration, each warrant entitled the holder to purchase one share of our common stock for an exercise price of $40 per share. The potential dilutive effect of the warrants did not consider the assumed proceeds to KMI upon exercise.


(b)	The holder of each convertible preferred share participated in our earnings by receiving preferred stock dividends through the mandatory conversion date of October 26, 2018 at which time our convertible preferred shares were converted to common shares.
