Note 4 Allowances for Loan and Lease Losses and Unfunded Loan Commitments and Letters of Credit

Allowance for Loan and Lease Losses

We maintain the ALLL at levels that we believe to be appropriate to absorb estimated probable credit losses incurred in the portfolios as of the balance sheet date. We use the two main portfolio segments – Commercial Lending and Consumer Lending – and develop and document the ALLL under separate methodologies for each of these segments as discussed in Note 1 Accounting Policies of our 2015 Form 10-K. A rollforward of the ALLL and associated loan data follows.

(a)TDRs individually evaluated for impairment exclude TDRs that were subsequently accounted for as held for sale loans, but continue to be disclosed as TDRs.
(b)Includes $149 million of loans collectively evaluated for impairment based upon collateral values and written down to the respective collateral value less costs to sell at June 30,
2016. Accordingly, there is no allowance recorded on these loans. The comparative amount as of June 30, 2015 was $174 million.
(c)Loans accounted for under the fair value option are not evaluated for impairment as these loans are accounted for at fair value. Accordingly, there is no allowance recorded on these loans.
(d)See Note 1 Accounting Policies in our 2015 Form 10-K for information on our change in derecognition policy effective December 31, 2015 for certain purchased impaired loans.

Allowance for Unfunded Loan Commitments and Letters of Credit

We maintain the allowance for unfunded loan commitments and letters of credit at a level we believe is appropriate to absorb estimated probable credit losses incurred on these unfunded credit facilities as of the balance sheet date as discussed in Note 1 Accounting Policies of our 2015 Form 10-K. A rollforward of the allowance is presented below.
