Accounting Policies [Abstract]

Schedule of Cost Method Investments

We have the following three equity investments which are accounted for at cost as they do not have readily determinable fair values: 

	December 31, 2018				December 31, 2017
	Ownership		Amount		Ownership		Amount
Colonial	6.00	%	$	11.4	6.00	%	$	11.4
Explorer (1)	12.62	%	48.6		12.62	%	48.6
Cleopatra	1.00	%	2.1		1.00	%	2.1
			$	62.1			$	62.1

⁽¹⁾ As part of the December 2017 Acquisition, our ownership in Explorer increased from 2.62% to 12.62% and we continued to account for this investment as a cost method investment as of December 31, 2018 and December 31, 2017. Our voting interest is in line with our percentage ownership and key governance issues pertaining to Explorer require a majority vote. Consequently, we do not control or exercise significant influence over Explorer.
