At June 30, 2017, we held 6,946 and 59 individual fixed maturity and equity securities, respectively, that were in an unrealized loss position, of which 1,222 and eight individual fixed maturity and equity securities, respectively, were in a continuous unrealized loss position for 12 months or more. We did not recognize the unrealized losses in earnings on these fixed maturity securities at June 30, 2017 because we neither intend to sell the securities nor do we believe that it is more likely than not that we will be required to sell these securities before recovery of their amortized cost basis. For fixed maturity securities with significant declines, we performed fundamental credit analyses on a security-by-security basis, which included consideration of credit enhancements, expected defaults on underlying collateral, review of relevant industry analyst reports and forecasts and other available market data.

For the three and six-month periods ended June 30, 2017, the aggregate fair value of available for sale securities sold was $7.6 billion and $23.4 billion, respectively, which resulted in net realized capital gains (losses) of $246 million and $402 million, respectively.

For the three and six-month periods ended June 30, 2016, the aggregate fair value of available for sale securities sold was $8.3 billion and $14.4 billion, respectively, which resulted in net realized capital gains of $1.1 billion and $760 million, respectively.

Evaluating Investments for Other-Than-Temporary Impairments

For a discussion of our policy for evaluating investments for other-than-temporary impairments see Note 6 to the Consolidated Financial Statements in the 2016 Annual Report.

Credit Impairments

The following table presents a rollforward of the cumulative credit losses in other-than-temporary impairments recognized in earnings for available for sale fixed maturity securities:

	Three Months Ended				Six Months Ended
	June 30,				June 30,

Balance, beginning of period	$	946	$	1,523	$	1,098	$	1,747
Increases due to:
Credit impairments on new securities subject to impairment losses		41		13		58		123

* Represents both accretion recognized due to changes in cash flows expected to be collected over the remaining expected term of the credit impaired securities and the accretion due to the passage of time.

Purchased Credit Impaired (PCI) Securities

We purchase certain RMBS securities that have experienced deterioration in credit quality since their issuance. We determine whether it is probable at acquisition that we will not collect all contractually required payments for these PCI securities, including both principal and interest. At acquisition, the timing and amount of the undiscounted future cash flows expected to be received on each PCI security is determined based on our best estimate using key assumptions, such as interest rates, default rates and prepayment speeds. At acquisition, the difference between the undiscounted expected future cash flows of the PCI securities and the recorded investment in the securities represents the initial accretable yield, which is accreted into Net investment income over their remaining lives on an effective yield basis. Additionally, the difference between the contractually required payments on the PCI securities and the undiscounted expected future cash flows represents the non-accretable difference at acquisition. The accretable yield and the non-accretable difference will change over time, based on actual payments received and changes in estimates of undiscounted expected future cash flows, which are discussed further below.

On a quarterly basis, the undiscounted expected future cash flows associated with PCI securities are re-evaluated based on updates to key assumptions. Declines in undiscounted expected future cash flows due to further credit deterioration as well as changes in the expected timing of the cash flows can result in the recognition of an other-than-temporary impairment charge, as PCI securities are subject to our policy for evaluating investments for other-than-temporary impairment. Changes to undiscounted expected future cash flows due solely to the changes in the contractual benchmark interest rates on variable rate PCI securities will change the accretable yield prospectively. Significant increases in undiscounted expected future cash flows for reasons other than interest rate changes are recognized prospectively as adjustments to the accretable yield.

The following tables present information on our PCI securities, which are included in bonds available for sale:

Pledged Investments

Secured Financing and Similar Arrangements

We enter into secured financing transactions whereby certain securities are sold under agreements to repurchase (repurchase agreements), in which we transfer securities in exchange for cash, with an agreement by us to repurchase the same or substantially similar securities. Our secured financing transactions also include those that involve the transfer of securities to financial institutions in exchange for cash (securities lending agreements). In all of these secured financing transactions, the securities transferred by us (pledged collateral) may be sold or repledged by the counterparties. These agreements are recorded at their contracted amounts plus accrued interest, other than those that are accounted for at fair value.

Pledged collateral levels are monitored daily and are generally maintained at an agreed-upon percentage of the fair value of the amounts borrowed during the life of the transactions. In the event of a decline in the fair value of the pledged collateral under these secured financing transactions, we may be required to transfer cash or additional securities as pledged collateral under these agreements. At the termination of the transactions, we and our counterparties are obligated to return the amounts borrowed and the securities transferred, respectively.

The following table presents the fair value of securities pledged to counterparties under secured financing transactions, including repurchase and securities lending agreements:

We also enter into agreements in which securities are purchased by us under agreements to resell (reverse repurchase agreements), which are accounted for as secured financing transactions and reported as short-term investments or other assets, depending on their terms. These agreements are recorded at their contracted resale amounts plus accrued interest, other than those that are accounted for at fair value. In all reverse repurchase transactions, we take possession of or obtain a security interest in the related securities, and we have the right to sell or repledge this collateral received.

The following table presents information on the fair value of securities pledged to us under reverse repurchase agreements:

Insurance – Statutory and Other Deposits

Total carrying values of cash and securities deposited by our insurance subsidiaries under requirements of regulatory authorities or other insurance-related arrangements, including certain annuity-related obligations and certain reinsurance treaties, were $5.2 billion and $4.9 billion at June 30, 2017 and December 31, 2016, respectively.

Other Pledges and Restrictions

Certain of our subsidiaries are members of Federal Home Loan Banks (FHLBs) and such membership requires the members to own stock in these FHLBs. We owned an aggregate of $119 million and $114 million of stock in FHLBs at June 30, 2017 and December 31, 2016, respectively. In addition, our subsidiaries have pledged securities available for sale and residential loans associated with advances from FHLB, with a fair value of $3.1 billion and $116 million, respectively, at June 30, 2017 and $3.4 billion and $17 million, respectively, at December 31, 2016, associated with advances from the FHLBs.

Certain GIAs have provisions that require collateral to be posted or payments to be made by us upon a downgrade of our long-term debt ratings. The actual amount of collateral required to be posted to the counterparties in the event of such downgrades, and the aggregate amount of payments that we could be required to make, depend on market conditions, the fair value of outstanding affected transactions and other factors prevailing at and after the time of the downgrade. The fair value of securities pledged as collateral with respect to these obligations was approximately $2.1 billion and $2.2 billion at June 30, 2017 and December 31, 2016, respectively. This collateral primarily consists of securities of the U.S. government and government sponsored entities and generally cannot be repledged or resold by the counterparties.

Investments held in escrow accounts or otherwise subject to restriction as to their use were $551 million and $523 million, comprised of bonds available for sale and short term investments at June 30, 2017 and December 31, 2016, respectively.
