Future premiums to be collected are undiscounted and are used to derive the discounted premium receivable asset recorded on Ambac's balance sheet. Future premiums to be earned, net of reinsurance relate to the unearned premium liability and deferred ceded premium asset recorded on Ambac’s balance sheet. The use of contractual lives for many bond types which do not have homogeneous pools of underlying collateral is required in the calculation of the premium receivable, as further described in Note 2. Basis of Presentation and Significant Accounting Principles in the Notes to Consolidated Financial Statements included in Ambac's Annual Report on Form 10-K/A for the year ended December 31, 2015. This results in a different premium receivable balance than if expected lives were considered. If installment paying policies are retired or prepay early, premiums reflected in the premium receivable asset and amounts reported in the above table for such policies may not be collected. Future premiums to be earned also considers the use of contractual lives for many bond types which do not have homogeneous pools of underlying collateral, which may result in different unearned premium than if expected lives were considered. If those bonds types are retired early, premium earnings may be negative in the period of call or refinancing.

Summary of Balance of Subrogation Recoveries and Related Claim Liabilities, by Estimation Approach

The balance of R&W subrogation recoveries and the related loss reserves, using the Random Sample estimation approach, at June 30, 2016 and December 31, 2015, are as follows:



Random Sample Approach	Gross loss reserves before subrogation recoveries ⁽¹⁾		Subrogation recoveries ⁽²⁾⁽³⁾			Gross loss reserves after subrogation recoveries
At June 30, 2016	$	1,370,594	$	(1,883,826	)	$	(513,232	)

At December 31, 2015	$	1,850,804	$	(2,829,575	)	$	(978,771	)


(1)	Includes unpaid RMBS claims, including accrued interest on Deferred Amounts, on policies allocated to the Segregated Account.

(2)

The amount of recorded subrogation recoveries related to each securitization is limited to ever-to-date paid and unpaid losses plus the present value of expected cash flows for each policy. To the extent losses have been paid but not yet fully recovered, the recorded amount of R&W subrogation recoveries may exceed the sum of the unpaid claims and the present value of expected cash flows for a given policy. The net cash inflow for these policies is recorded as a “Subrogation recoverable” asset. For those transactions where the subrogation recovery is less than the sum of unpaid claims and the present value of expected cash flows, the net cash outflow for these policies is recorded as a “Loss and loss expense reserves” liability.

(3)

The sponsor’s repurchase obligation may differ depending on the terms of the particular transaction and the status of the specific loan, such as whether it is performing or has been liquidated or charged off. The estimated subrogation recovery for these transactions is based primarily on loan level data provided through trustee reports received in the normal course of our surveillance activities or provided by the sponsor. While this data may not include all the components of the sponsor’s contractual repurchase obligation we believe it is the best information available to estimate the subrogation recovery.

Summary of Rollforward of RMBS Subrogation, by Estimation Approach

Below is the rollforward of R&W subrogation, by random sample estimation approach, for the affected periods:



	Six Months Ended June 30,
	2016			2015
Discounted RMBS subrogation (gross of reinsurance) at beginning of period	$	2,829,575		$	2,523,540
Changes recognized during the period:
Impact of sponsor actions ⁽¹⁾	(995,000		)	—
All other changes ⁽²⁾	49,251			33,034
Discounted RMBS subrogation (gross of reinsurance) at end of period	$	1,883,826		$	2,556,574


(1)	Sponsor actions include loan repurchases, direct payments to Ambac and other contributions.

(2)

All other changes which may impact RMBS subrogation recoveries include changes in actual or projected collateral performance, changes in the creditworthiness of a sponsor and/or the projected timing of recoveries. All other changes may also include estimates of potential sponsor settlements that may not have been subject to a sampling approach or have been executed but the settlement amounts have not yet been received. Those that have not been subject to a sampling approach are not material to Ambac’s financial results and therefore are included in the Random Sample column of this table.
