Note 13.  Financing Arrangements We routinely enter into accounts receivable securitization and factoring programs .
We account for transfers of receivables pursuant to these programs as a sale and remove them from our consolidated balance sheet.
At December 31, 2016 , our most significant program in place was the U. S.  securitization program, which was amended in May 2016 and originally entered into in October of 2015.
Under the program, we are entitled to receive cash consideration of up to $800 million (which we elected to reduce to $500 million , effective February 21, 2017) and a receivable for the remainder of the purchase price (the “Deferred Purchase Price”).
This securitization program utilizes a bankruptcyremote special-purpose entity (“SPE”).
The SPE is wholly-owned by a subsidiary of Kraft Heinz and its sole business consists of the purchase or acceptance, through capital contributions of receivables and related assets, from a Kraft Heinz subsidiary and subsequent transfer of such receivables and related assets to a bank.
Although the SPE is included in our consolidated financial statements, it is a separate legal entity with separate creditors who will be entitled, upon its liquidation, to be satisfied out of the SPE's assets prior to any assets or value in the SPE becoming available to Kraft Heinz or its subsidiaries.
The assets of the SPE are not available to pay creditors of Kraft Heinz or its subsidiaries.
This program expires in May 2017.
In addition to the U. S.  securitization program, we have accounts receivable factoring programs denominated in Australian dollars, New Zealand dollars, British pound sterling, euros, and Japanese yen.
Under these programs, we generally receive cash consideration up to a certain limit and a receivable for the Deferred Purchase Price.
There is no Deferred Purchase Price associated with the Japanese yen contract.
Related to these programs, our aggregate cash consideration limit, after applying applicable hold-backs, was $245 million U. S.  dollars at December 31, 2016.
Generally, each of these programs automatically renews annually until terminated by either party.
The cash consideration and carrying amount of receivables removed from the consolidated balance sheets in connection with the above programs were $904 million at December 31, 2016 and $267 million at January 3, 2016 .
The fair value of the Deferred Purchase Price for the programs was $129 million at December 31, 2016 and $583 million at January 3, 2016 .
The Deferred Purchase Price is included in sold receivables on the consolidated balance sheets and had a carrying value which approximated its fair value at December 31, 2016 and January 3, 2016 .
The proceeds from these sales are recognized on the consolidated statements of cash flows as a component of operating activities.
We act as servicer for these arrangements and have not recorded any servicing assets or liabilities for these arrangements as of December 31, 2016 and January 3, 2016 because they were not material to the financial statements.
PRUDENTIAL FINANCIAL, INC.  Notes to Consolidated Financial Statements The following table sets forth a rollforward of pre-tax amounts remaining in OCI related to fixed maturity securities with credit loss impairments recognized in earnings, for the periods indicated:
## Table 1 ##
(1) Represents circumstances where the Company determined in the current period that it intends to sell the security or it is more likely than not that it will be required to sell the security before recovery of the security’s amortized cost.
Assets Supporting Experience-Rated Contractholder Liabilities The following table sets forth the composition of “Assets supporting experience-rated contractholder liabilities,” as of the dates indicated:
## Table 2 ##
(1) Includes publicly-traded agency pass-through securities and collateralized mortgage obligations.
(2) Includes credit-tranched securities collateralized by sub-prime mortgages, auto loans, credit cards, education loans and other asset types.
Includes collateralized loan obligations at fair value of $1,028 million and $943 million as of December 31, 2018 and 2017, respectively, all of which were rated AAA.
(3) As a percentage of amortized cost, 93% and 92% of the portfolio was considered high or highest quality based on NAIC or equivalent ratings, as of December 31, 2018 and 2017, respectively.
(4) As a percentage of amortized cost, 78% and 80% of the portfolio consisted of public securities as of December 31, 2018 and 2017, respectively.
The net change in unrealized gains (losses) from assets supporting experience-rated contractholder liabilities still held at period end, recorded within “Other income (loss),” was $(778) million, $300 million and $75 million during the years ended December 31, 2018, 2017 and 2016, respectively.
Equity Securities The net change in unrealized gains (losses) from equity securities, still held at period end, recorded within “Other income (loss),” was $(1,157) million during the year ended December 31, 2018.
The net change in unrealized gains (losses) from equity securities, still held at period end, recorded within “Other comprehensive income (loss),” was $(494) million and $760 million during the years ended December 31, 2017 and 2016, respectively.
Benefits and expenses increased $735 million.
Excluding the impact of our annual reviews and update of assumptions and other refinements, as discussed above, benefits and expenses increased $709 million primarily driven by an increase in policyholders’ benefits, including the change in policy reserves, related to the increase in premiums discussed above.
Account Values Account values are a significant driver of our operating results, and are primarily driven by net additions (withdrawals) and the impact of market changes.
The income we earn on most of our fee-based products varies with the level of fee-based account values, since many policy fees are determined by these values.
The investment income and interest we credit to policyholders on our spread-based products varies with the level of general account values.
To a lesser extent, changes in account values impact our pattern of amortization of DAC and VOBA and general and administrative expenses.
The following table shows the changes in the account values and net additions (withdrawals) of Retirement segment products for the periods indicated.
Net additions (withdrawals) are plan sales and participant deposits or additions, as applicable, minus plan and participant withdrawals and benefits.
Account values include both internally- and externallymanaged client balances as the total balances drive revenue for the Retirement segment.
For more information on internally-managed balances, see “—PGIM.
