Our Competitive Strengths Our long operating history, through a range of challenging economic cycles, forms the basis of our competitive strengths.
From our community bank roots, we bring a commitment to strong customer relationships, local service and an active involvement in the communities we serve.
Our acquisitions enabled us to develop significant scale in highly desirable markets and broad product capabilities.
The actions taken since the global financial crisis have resulted in a business model with solid asset quality, a stable core deposit mix and a superior capital position.
In particular, we believe that the following strengths differentiate us from our competitors and provide a strong foundation from which to execute our strategy to deliver enhanced growth, profitability and returns.  ?
Significant Scale with Strong Market Penetration in Attractive Geographic Markets: We believe our market share and scale in our footprint is central to our success and growth.

As of June 30, 2016, we ranked second by retail deposit market share in the New England region (Maine, New Hampshire, Vermont, Massachusetts, Rhode Island and Connecticut) and we ranked in the top five in nine of our ten key MSAs, including Providence, Boston, Pittsburgh, Philadelphia and Cleveland.
(1) We believe this strong market share in our core regions, which have relatively diverse economies and affluent demographics, will help us achieve our long-term growth objectives.
The following table sets forth information regarding our competitive position in our principal MSAs:

CITIZENS FINANCIAL GROUP, INC.  MANAGEMENT’S DISCUSSION AND ANALYSIS
## Table 1 ##
(1) As discussed in Note 1 “Significant Accounting Policies” to our audited Consolidated Financial Statements in Part II, Item 8 — Financial Statements and Supplementary Data, included in this report, the ALLL is reviewed separately for commercial and retail loans, and the ALLL for each includes an adjustment for qualitative allowance that includes certain risks, factors and events that might not be measured in the statistical analysis.
As a result of this adjustment, the unallocated allowance was absorbed into the separately measured commercial and retail qualitative allowance during 2013.
(2) During December 2016, changes to the incurred loss period were reflected as components of the provision for retail property secured products.
During December 2013, we updated our estimate of the incurred loss period for certain residential mortgages.
This change reflected an analysis of defaulted borrowers and aligned to management’s view that incurred but unrealized losses emerge differently during various points of an economic/business cycle.
Allocation of the Allowance for Loan and Lease Losses The following table presents an allocation of the ALLL by class and the percent of each class of loans and leases to the total loans and leases:
## Table 2 ##
The allowance for credit losses totaled $1.3 billion at December 31, 2016 and 2015.
Our ALLL was 1.15% of total loans and leases and 118% of nonperforming loans and leases as of December 31, 2016 compared with 1.23% and 115%, respectively, as of December 31, 2015.
There were no material changes in assumptions or estimation techniques compared with prior periods that impacted the determination of the current period’s ALLL and the reserve for unfunded lending commitments.
However, as part of the annual review of loss emergence periods, the incurred loss periods for retail property secured loans were extended.
Overall credit quality continued to improve reflecting growth in lower risk retail loans and modest increases in commercial categories.
Nonperforming loans and leases of $1.0 billion as of December 31, 2016 decreased $15 million from December 31, 2015, reflecting improvements in retail real estate secured categories offset by an increase in commercial nonperforming assets, largely driven by commodities-related businesses.
Net charge-offs of $335 million increased $51 million, or 18%, from $284 million in 2015, as a $59 million increase in commercial, largely tied to commodities-related businesses, and a reduction in commercial real estate recoveries more than offset an $8 million decrease in retail.
Net charge-offs of 0.32% of average total loans and leases remained relatively stable with 0.30% in 2015.
See Note 5 “Allowance for Credit Losses, Nonperforming Assets, and Concentrations of Credit Risk” to our audited Consolidated Financial Statements in Part II, Item 8 — Financial Statements and Supplementary Data, included in this report.
Other Long Term Debt In December 2012, the Company entered into a $50.0 million recourse loan collateralized by the land, buildings and tenant improvements comprising the Company’s corporate headquarters.
The loan has a seven year term and maturity date of December 2019.
The loan bears interest at one month LIBOR plus a margin of 1.50%, and allows for prepayment without penalty.
The loan includes covenants and events of default substantially consistent with the Company’s credit agreement discussed above.
The loan also requires prior approval of the lender for certain matters related to the property, including transfers of any interest in the property.
As of December 31, 2017 and 2016, the outstanding balance on the loan was $40.0 million and $42.0 million, respectively.
The weighted average interest rate on the loan was 2.5% and 2.0% for the years ended December 31, 2017 and 2016, respectively.
The following are the scheduled maturities of long term debt as of December 31, 2017:
## Table 3 ##
Interest expense, net was $34.5 million, $26.4 million, and $14.6 million for the years ended December 31, 2017, 2016 and 2015, respectively.
Interest expense includes the amortization of deferred financing costs, bank fees, capital and built-to-suit lease interest and interest expense under the credit and other long term debt facilities.
Amortization of deferred financing costs was $1.3 million, $1.2 million, and $0.8 million for the years ended December 31, 2017, 2016 and 2015, respectively.
The Company monitors the financial health and stability of its lenders under the credit and other long term debt facilities, however during any period of significant instability in the credit markets lenders could be negatively impacted in their ability to perform under these facilities.7.
Commitments and Contingencies Obligations Under Operating Leases The Company leases warehouse space, office facilities, space for its brand and factory house stores and certain equipment under non-cancelable operating leases.
The leases expire at various dates through 2033, excluding extensions at the Company’s option, and include provisions for rental adjustments.
The table below includes executed lease agreements for brand and factory house stores that the Company did not yet occupy as of December 31, 2017 and does not include contingent rent the Company may incur at its stores based on future sales above a specified minimum or payments made for maintenance, insurance and real estate taxes.
The following is a schedule of future minimum lease payments for non-cancelable real property operating leases as of December 31, 2017 as well as
