As of June 30, 2017 and 2016, the recorded bases of common and preferred stock that are restricted for more than one year or are not publicly traded were $1.1 billion and $767 million, respectively. These investments are carried at cost and are reviewed quarterly for indicators of other-than-temporary impairment. It is not practicable for us to reliably estimate the fair value of these investments.

As of June 30, 2017, collateral received under agreements for loaned securities was $3.7 billion, which was primarily comprised of U.S. government and agency securities. As of June 30, 2016, collateral received under agreements for loaned securities was $294 million, which was primarily comprised of cash.

Unrealized Losses on Investments

Investments with continuous unrealized losses for less than 12 months and 12 months or greater and their related fair values were as follows:

	Less than 12 Months					12 Months or Greater							Total Unrealized Losses

(In millions)	Fair Value		Unrealized Losses			Fair Value		Unrealized Losses			Total Fair Value

Total	$	12,188	$	(165	)	$	1,967	$	(137	)	$	14,155	$	(302	)

Unrealized losses from fixed-income securities are primarily attributable to changes in interest rates. Unrealized losses from domestic and international equities are due to market price movements. Management does not believe any remaining unrealized losses represent other-than-temporary impairments based on our evaluation of available evidence.
