Basis of Financial Statement Presentation	Basis of Financial Statement Presentation (a) Nature of Operations Sterling Bancorp (the “Company”) is a Delaware corporation, a bank holding company and a financial holding company headquartered in Montebello, New York, that owns all of the outstanding shares of common stock of Sterling National Bank (the “Bank”), its principal subsidiary. The Bank is a full-service regional bank specializing in the delivery of services and solutions to business owners, their families and consumers within the communities it serves through teams of dedicated and experienced relationship managers. (b) Basis of Presentation The consolidated financial statements in this Quarterly Report on Form 10-Q include the accounts of the Company and all other entities in which the Company has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. The accounting and financial reporting policies the Company follows conform, in all material respects, to accounting principles generally accepted in the United States (“GAAP”) and to general practices within the banking industry, which includes regulatory reporting instructions. The consolidated financial statements in this Quarterly Report on Form 10-Q have not been audited by an independent registered public accounting firm, but, in the opinion of management, reflect all adjustments necessary for a fair presentation of the Company’s financial position and results of operations. All such adjustments were of a normal and recurring nature. The consolidated financial statements have been prepared in accordance with GAAP and with the instructions to Form 10-Q adopted by the Securities and Exchange Commission (the “SEC”). Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our consolidated financial statements, and notes thereto, for the year ended December 31, 2015 , included in our Annual Report on Form 10-K filed with the SEC on February 29, 2016 (the “2015 Form 10-K”). Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period. Certain items in prior financial statements have been reclassified to conform to the current presentation. (c) Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income, expense and contingencies at the date of the financial statements. Actual results could differ significantly from these estimates. The allowance for loan losses and the status of contingencies are particularly subject to change. (d) Merger with Hudson Valley Holding Corp. On June 30, 2015 , Hudson Valley Holding Corp. (“HVHC”) merged with and into the Company (the “HVB Merger”). In connection with the HVB Merger, Hudson Valley Bank, the principal subsidiary of HVHC, merged with and into the Bank.

Acquisitions	Acquisitions NSBC Acquisition On March 31, 2016 , the Bank acquired 100% of the outstanding equity interests of NewStar Business Credit LLC, a Delaware limited liability company (“NSBC” and, its acquisition, the “NSBC Acquisition”). NSBC is a provider of asset-based lending solutions to middle market commercial clients. NSBC’s loans were $320,447 on the acquisition date and consisted of 100% floating-rate assets. The Bank paid a premium on the balance of gross loans receivable acquired of 5.90% , or $18,906 . The Bank assumed $4,839 of liabilities, which consisted mainly of cash collateral on loans outstanding. The Bank recognized a customer list intangible asset of $1,500 that is being amortized over its 24 -month estimated life and $25,698 of goodwill. The Bank recorded a $1,500 restructuring charge consisting mainly of retention and severance compensation, IT contract terminations and professional fees. HVB Merger On June 30, 2015 , the Company completed the HVB Merger. Under the terms of the HVB Merger agreement, HVHC shareholders received 1.92 shares of the Company’s common stock for each share of HVHC common stock, which resulted in the issuance of 38,525,154 shares. Based on the Company’s closing stock price of $14.63 per share on June 29, 2015 , the aggregate consideration paid to HVHC shareholders was $566,307 , which, in accordance with the HVB Merger agreement, also included the in-the-money cash value of outstanding HVHC stock options, the fair value of outstanding HVHC restricted stock awards and cash in lieu of fractional shares. Consistent with the Company’s strategy, the primary reason for the HVB Merger was the expansion of the Company’s geographic footprint in the greater New York metropolitan region and beyond. The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their fair values as of June 30, 2015 , based on management’s best estimate and using the information available as of the HVB Merger date. The application of the acquisition method of accounting resulted in the recognition of goodwill of $269,757 and a core deposit intangible of $33,839 . As of June 30, 2015 , HVHC had assets with a net book value of approximately $288,208 , including loans with a net book value of approximately $1,816,767 , and deposits with a net book value of approximately $3,160,746 . The table below summarizes the amounts recognized as of the HVB Merger date for each major class of assets acquired and liabilities assumed, the estimated fair value adjustments and the amounts recorded in the Company’s financial statements at fair value at the HVB Merger date: Consideration paid through Sterling Bancorp common stock issued to HVHC shareholders $ 566,307 HVHC net book value Fair value adjustments As recorded at acquisition Cash and cash equivalents $ 878,988 $ — $ 878,988 Investment securities 713,625 217 (a) 713,842 Loans 1,816,767 (24,248 ) (b) 1,792,519 Federal Reserve Bank stock 5,830 — 5,830 Bank owned life insurance 44,231 — 44,231 Premises and equipment 11,918 4,925 (c) 16,843 Accrued interest receivable 7,392 — 7,392 Other intangible assets — 33,839 (d) 33,839 Other real estate owned 222 — 222 Other assets 32,639 (7,931 ) (e) 24,708 Deposits (3,160,746 ) — (3,160,746 ) Other borrowings (25,366 ) — (25,366 ) Other liabilities (37,292 ) 1,540 (f) (35,752 ) Total identifiable net assets $ 288,208 $ 8,342 $ 296,550 Goodwill recorded in the HVB Merger $ 269,757 Explanation of certain fair value related adjustments: (a) Represents the fair value adjustment on investment securities held to maturity. (b) Represents the elimination of HVHC ’ s allowance for loan losses and an adjustment of the net book value of loans to estimated fair value, which includes an interest rate mark and credit mark adjustment. (c) Represents an adjustment to reflect the fair value of HVHC-owned real estate as determined by independent appraisals, which will be amortized on a straight-line basis over the estimated useful lives of the individual assets. (d) Represents intangible assets recorded to reflect the fair value of core deposits. The core deposit asset was recorded as an identifiable intangible asset and will be amortized on an accelerated basis over the estimated average life of the deposit base. (e) Represents an adjustment in net deferred tax assets resulting from the fair value adjustments related to the acquired assets, liabilities assumed and identifiable intangibles recorded. (f) Represents the elimination of HVHC’s deferred rent liability. The fair values for loans acquired from HVHC were estimated using cash flow projections based on the remaining maturity and repricing terms. Cash flows were adjusted by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value using a risk-adjusted market rate for similar loans. For collateral dependent loans with deteriorated credit quality, fair value was estimated by analyzing the value of the underlying collateral, assuming the fair values of the loans were derived from the eventual sale of the collateral. These values were discounted using market derived rates of return, with consideration given to the period of time and costs associated with the foreclosure and disposition of the collateral. There was no carryover of HVHC’s allowance for loan losses associated with the loans that were acquired, as the loans were initially recorded at fair value on the date of the HVB Merger. Acquired loan portfolio data in the HVB Merger is presented below: Fair value of acquired loans at acquisition date Gross contractual amounts receivable at acquisition date Best estimate at acquisition date of contractual cash flows not expected to be collected Acquired loans with evidence of deterioration since origination $ 96,973 $ 122,104 $ 19,024 Acquired loans with no evidence of deterioration since origination 1,695,546 1,974,740 37,520 The core deposit intangible asset recognized is being amortized over its estimated useful life of approximately 10 years utilizing the sum-of-the-years digits method. Other intangibles consist of below market rents, which are amortized over the remaining life of each lease using the straight-line method. Goodwill is not amortized for book purposes; however, it is reviewed at least annually for impairment and is not deductible for tax purposes. The fair value of land, buildings and equipment was estimated using appraisals. Buildings will be amortized over their estimated useful lives of approximately 30 years. Improvements and equipment will be amortized or depreciated over their estimated useful lives ranging from one to five years. The fair value of retail demand and interest bearing deposit accounts was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. The fair value of time deposits was estimated by discounting the contractual future cash flows using market rates offered for time deposits of similar remaining maturities. Management concluded the carrying value was an appropriate estimate of fair value for these deposits. Direct acquisition and other charges incurred in connection with the HVB Merger were expensed as incurred and totaled $14,625 for the three and six months ended June 30, 2015. These expenses were mainly for financial advisory fees, legal and accounting fees, severance and retention compensation, management change-in-control payments, public relations and communications expense, and were recorded in “Merger-related expenses” on the consolidated statement of operations. Other integration costs of the HVB Merger for the three months and six months ended June 30, 2015 included a charge for asset write-downs, information technology services and other contract terminations, employee retention and severance compensation and impairment of leases and facilities which totaled $28,055 , which was recorded in “Other non-interest expense” in the consolidated statement of operations. There were no merger-related expenses or other integration costs incurred in connection with the HVB Merger in 2016. FCC Acquisition On May 7, 2015, the Bank acquired a factoring portfolio from FCC, LLC, a subsidiary of First Capital Holdings, Inc. (“FCC”), with an outstanding factoring receivables balance of approximately $44,500 . The total consideration included a premium of $1,000 in addition to the outstanding receivables balance. Damian Acquisition On February 27, 2015 , the Bank acquired 100% of the outstanding common stock of Damian Services Corporation (“Damian”) a payroll services provider located in Chicago, Illinois, for total consideration of $24,670 in cash. In connection with the acquisition, the Bank acquired $22,307 of outstanding payroll finance loans and assumed $14,560 of liabilities. The Bank recognized a customer list intangible asset of $8,950 that is being amortized over its 16 year estimated life, and $11,930 of goodwill. The Bank also recognized a $1,500 restructuring charge consisting mainly of retention and severance compensation and asset write-downs related to the consolidation of Damian’s operations, and approximately $300 of legal fees.

Declines in the fair value of held to maturity and available for sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income. In estimating other than temporary impairment (“OTTI”) losses, management considers, among other things, (i) the length of time and the extent to which the fair value has been less than cost; (ii) the financial condition and near-term prospects of the issuer; and (iii) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in cost. Management has the ability and intent to hold the securities classified as held to maturity in the table above until they mature, at which time the Company anticipates it will receive full value for the securities. Furthermore, as of June 30, 2016 , management did not have the intent to sell any of the securities classified as available for sale in the table above and believes that it is more likely than not that the Company will not have to sell any such securities before a recovery of cost. Any unrealized losses are largely due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Management does not believe any of the securities are impaired due to reasons of credit quality. As of June 30, 2016 , management believes the impairments detailed in the table above are temporary. Securities pledged for borrowings at the FHLB and other institutions, and securities pledged for municipal deposits and other purposes, were as follows for the periods presented below: June 30, December 31, 2016 2015 Available for sale securities pledged for borrowings, at fair value $ 88,006 $ 101,994 Available for sale securities pledged for municipal deposits, at fair value 827,070 849,186 Available for sale securities pledged for customer back-to-back swaps, at fair value 5,973 1,839 Held to maturity securities pledged for borrowings, at amortized cost 102,500 206,337 Held to maturity securities pledged for municipal deposits, at amortized cost 454,747 327,589 Total securities pledged $ 1,478,296 $ 1,486,945

These loans are classified as purchased credit impaired loans (“PCI loans”). There were no non-accrual warehouse lending loans at June 30, 2016 or December 31, 2015 . When the ultimate collectibility of the total principal of an impaired loan is in doubt and the loan is on non-accrual status, all payments are applied to principal, under the cost recovery method. When the ultimate collectibility of the total principal of an impaired loan is not in doubt and the loan is on non-accrual status, contractual interest is credited to interest income when received, under the cash basis method. At June 30, 2016 and December 31, 2015 , the recorded investment of residential mortgage loans that were formally in the process of foreclosure was $10,086 and $9,638 , respectively, which are included in non-accrual residential mortgage loans above.

Evaluation of impairment is treated the same across all classes of loans on a loan-by-loan basis, except residential mortgage loans and home equity lines of credit with an outstanding balance of $500 or less, which are evaluated for impairment on a homogeneous pool basis. When management identifies a loan as impaired, the impairment is measured based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, except when the sole remaining source of repayment of the loan is the operation or liquidation of the collateral. In these cases, management uses the current fair value of the collateral, less selling costs when foreclosure or liquidation is probable, instead of discounted cash flows. If management determines that the value of the impaired loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is generally recognized through a charge-off to the allowance for loan losses. The carrying amount of PCI loans is presented in the tables above. At June 30, 2016 , the net recorded amount of PCI loans was $107,575 , which included $36,976 of C&I loans acquired in the NSBC Acquisition. There was $472 and $272 included in the allowance for loan losses associated with PCI loans at June 30, 2016 and December 31, 2015 , respectively.

The Bank analyzes loans individually by classifying the loans by credit risk, except residential mortgage loans, HELOC and other consumer loans, which are evaluated on a homogeneous pool basis unless the loan balance is greater than $500 . This analysis is performed at least quarterly on all criticized/classified loans. The Bank uses the following definitions of risk ratings: 1 and 2 - These grades include loans that are secured by cash, marketable securities or cash surrender value of life insurance policies. 3 - This grade includes loans to borrowers with strong earnings and cash flow and that have the ability to service debt. The borrower’s assets and liabilities are generally well matched and are above average quality. The borrower has ready access to multiple sources of funding, including alternatives such as term loans, private equity placements or trade credit. 4 - This grade includes loans to borrowers with above average cash flow, adequate earnings and debt service coverage ratios. The borrower generates discretionary cash flow, assets and liabilities are reasonably matched, and the borrower has access to other sources of debt funding or additional trade credit at market rates. 5 - This grade includes loans to borrowers with adequate earnings and cash flow and reasonable debt service coverage ratios. Overall leverage is acceptable and there is average reliance upon trade credit. Management has a reasonable amount of experience and depth, and owners are willing to invest available outside capital as necessary. 6 - This grade includes loans to borrowers where there is evidence of some strain, earnings are inconsistent and volatile, and the borrowers’ outlook is uncertain. Generally, such borrowers have higher leverage than those with a better risk rating. These borrowers typically have limited access to alternative sources of bank debt and may be dependent upon debt funding for working capital support. 7 - Special Mention (OCC definition) - Other Assets Especially Mentioned (“OAEM”) are loans that have potential weaknesses which may, if not reversed or corrected, weaken the asset or inadequately protect the Bank’s credit position at some future date. Such assets constitute an undue and unwarranted credit risk but not to the point of justifying a classification of “Substandard.” The credit risk may be relatively minor yet constitute an unwarranted risk in light of the circumstances surrounding a specific asset. 8 - Substandard (OCC definition) - These loans are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness that jeopardizes the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some losses if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified as substandard. 9 - Doubtful (OCC definition) - These loans have all the weakness inherent in one classified as “Substandard” with the added characteristics that the weakness makes collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is extremely high, but, because of certain important and reasonably specific pending factors which may work to the advantage and strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors may include a proposed merger, acquisition, or liquidating procedures, capital injection, perfecting liens or additional collateral and refinancing plans. 10 - Loss (OCC definition) - These loans are charged-off because they are determined to be uncollectible and unbankable assets. This classification does not indicate that the asset has no absolute recovery or salvage value, but rather it is not practical or desirable to defer writing-off this asset even though partial recovery may be affected in the future. Losses should be taken in the period in which they are determined to be uncollectible. Loans that are risk-rated 1 through 6 as defined above are considered to be pass-rated loans.

As a member of the FHLB, the Bank may borrow up to a discounted percentage of the amount of eligible mortgages and securities that have been pledged as collateral under a blanket security agreement. As of June 30, 2016 and December 31, 2015 , the Bank had total residential mortgage and commercial real estate loans pledged after discount of $2,237,263 and $2,050,982 , respectively. In addition to the pledged mortgages, the Bank had also pledged securities to secure borrowings, which are disclosed in Note 3. “Securities.” As of June 30, 2016 , the Bank had unused borrowing capacity at the FHLB of $1,346,347 and may increase its borrowing capacity by pledging securities not required to be pledged for other purposes with a collateral value of approximately $1,360,789 . FHLB borrowings included $200,000 at December 31, 2015 that were putable quarterly at the discretion of the FHLB. These borrowings had a weighted average remaining term to the contractual maturity dates of approximately 1.31 years at December 31, 2015 and a weighted average interest rate of 4.23% . The Company redeemed these borrowings on March 31, 2016, together with $20,000 of other borrowings with an interest rate of 3.57% . The Company incurred a loss on extinguishment of debt associated with these repayments of $8,716 , which is included in non-interest expense in the consolidated statements of operations. Other borrowings (repurchase agreements). The Bank enters into sales of securities under agreements to repurchase. These repurchase agreements facilitate the needs of our customers and a portion of our secured short-term funding needs. Securities sold under agreements to repurchase at June 30, 2016 and December 31, 2015 are secured short-term borrowings that mature in one to 45 days and are generally renewed on a continuous basis. Repurchase agreements are stated at the amount of cash received in connection with these transactions. The securities pledged under these repurchase agreements fluctuate in value due to market conditions. The Bank is obligated to promptly transfer additional securities if the market value of the securities falls below the repurchase agreement price. Securities pledged as collateral under repurchase agreements are maintained with our safekeeping agents. Senior Notes. On July 2, 2013 , the Company issued $100,000 principal amount of 5.50% fixed rate senior notes (the “Senior Notes”) through a private placement at a discount of 1.75% . The cost of issuance was $303 , and at June 30, 2016 and December 31, 2015 the unamortized discount was $901 and $1,107 , respectively, which will be accreted to interest expense over the life of the Senior Notes, resulting in an effective yield of 5.98% . Interest is due semi-annually in arrears on January 2 and July 2 until maturity on July 2, 2018 . Subordinated Notes . On March 29, 2016 , the Bank issued $110,000 principal amount of 5.25% fixed-to-floating rate subordinated notes (the “Subordinated Notes”) through a private placement at a discount of 1.25% . The cost of issuance was $500 , and at June 30, 2016 the unamortized discount was $1,839 , which will be accreted to interest expense over the life of the subordinated notes, resulting in an effective yield of 5.47% . Interest is due semi-annually in arrears on April 1 and October 1 of each year, beginning on October 1, 2016 , until April 1, 2021 . From and including April 1, 2021 , the Subordinated Notes will bear interest at a floating rate per annum equal to three-month LIBOR plus 3.937% , payable quarterly on January 1 , April 1 , July 1 and October 1 of each year, beginning on July 1, 2021 , through maturity on April 1, 2026 or earlier redemption. The Subordinated Notes are redeemable by the Bank, in whole or in part, on April 1, 2021 and each interest payment date thereafter. The Subordinated Notes are redeemable in whole at any time upon certain specified events. The Subordinated Notes are unsecured, subordinated obligations of the Bank and are subordinated in right of payment to all of the Bank’s existing and future senior indebtedness, including claims of depositors and general creditors. The Subordinated Notes qualify as Tier 2 capital for regulatory purposes, see Note 15. “Stockholders’ Equity,” for additional information. Revolving line of credit. On June 28, 2016, the Company amended its revolving line of credit facility (the “Credit Facility”), and increased the maximum amount available from $15,000 to $25,000 .

Loans under the Credit Facility bear interest at one-month LIBOR plus 1.25% . Under the terms of the Credit Facility, the Company and the Bank must maintain certain ratios related to capital, non-performing assets to capital, reserves to non-performing loans and debt service coverage.

Derivative Instruments and Hedges, Assets [Abstract]
Derivatives	Derivatives The Company has entered into certain interest rate swap contracts that are not designated as hedging instruments. These derivative contracts relate to transactions in which the Company enters into an interest rate swap with a customer while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each swap transaction, the Company agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, the Company agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows the Company’s customers to effectively convert a variable rate loan to a fixed rate. Because the Company acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts for the most part offset each other and do not significantly impact the Company’s results of operations. The Company pledged cash of $1,525 and investment securities with a fair value of $5,973 as of June 30, 2016 as collateral for the swaps with another financial institution. The Company may need to post additional collateral to swap counterparties in the future in proportion to potential increases in unrealized loss positions. The Company does not typically require its commercial customers to post cash or securities as collateral on its program of back-to-back swaps. However, certain language is written into the International Swaps and Derivatives Association agreement and loan documents where, in default situations, the Company is allowed to access collateral supporting the loan relationship to recover any losses suffered on the derivative asset or liability. Summary information as of June 30, 2016 and December 31, 2015 regarding these derivatives is presented below: Notional amount Average maturity (in years) Weighted average fixed rate Weighted average variable rate Fair value June 30, 2016 3rd party interest rate swap $ 185,342 5.70 3.91 1 m Libor + 2.27 $ 7,498 Customer interest rate swap (185,342 ) 5.70 3.91 1 m Libor + 2.27 (7,498 ) December 31, 2015 3rd party interest rate swap 87,094 5.44 4.09 1 m Libor + 2.15 1,839 Customer interest rate swap (87,094 ) 5.44 4.09 1 m Libor + 2.15 (1,839 ) The Company enters into various commitments to sell real estate loans into the secondary market. Such commitments are considered to be derivative financial instruments; however, the fair value of these commitments is not material.

No valuation allowance was recorded against deferred tax assets at June 30, 2016 , as management believes it is more likely than not that all of the deferred tax assets will be realized because they were supported by recoverable taxes paid in prior years. There were no unrecognized tax benefits during any of the reported periods. Interest and/or penalties related to income taxes are reported as a component of other non-interest expense. Such amounts were not material during the reported periods. The Company is generally no longer subject to examination by Federal, state and local taxing authorities for fiscal years prior to September 30, 2012.

Compensation and Retirement Disclosure [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company has active stock-based compensation plans, as described below. The Company’s stockholders approved the 2015 Omnibus Equity and Incentive Plan (the “2015 Plan”) on May 28, 2015. The 2015 Plan permits the grant of stock options, stock appreciation rights, restricted stock (both time-based and performance-based), restricted stock units, deferred stock and other stock-based awards. The total number of shares that may be awarded under the 2015 Plan is 2,800,000 shares plus the remaining shares available for grant under the stockholder approved 2014 Stock Incentive Plan (the “2014 Plan”) as of the adoption of the 2015 Plan. At June 30, 2016 , there were in aggregate 3,632,934 shares available for future grant under the 2015 Plan. The approval of the 2015 Plan resulted in the termination of the 2014 Plan. Awards granted under the 2014 Plan that were outstanding as of May 28, 2015 will continue to be governed by the 2014 Plan document; however, no future grants will be made under the 2014 Plan. Under the 2015 Plan, one share is deducted from the 2015 Plan for every share that is awarded and delivered under the 2015 Plan. Restricted stock awards are granted with a fair value equal to the market price of the Company’s common stock at the date of grant. Stock option awards are granted with a strike price that is equal to the market price of the Company’s stock at the date of grant. The awards generally vest in equal installments annually on the anniversary date and have total vesting periods ranging from 1 to 5 years and stock options having 10 -year contractual terms. In addition to the 2015 Plan and the 2014 Plan, the Company previously granted awards under its 2011 Employment Inducement Stock Program, which included options to purchase 107,526 shares of common stock and restricted stock awards covering 29,550 shares of common stock, both of which vested in four equal installments through July 2015. In connection with the Provident Merger, the Company granted 104,152 options at an exercise price of $14.25 per share pursuant to a Registration Statement on Form S-8 under which the Company assumed all outstanding fully-vested Legacy Sterling stock options, which expire March 15, 2017 . The Company also granted 95,991 shares under the Sterling Bancorp 2013 Employment Inducement Award Plan to certain executive officers of Legacy Sterling. In addition, the Company issued 255,973 shares of restricted stock from shares available under a prior plan to certain executives of Legacy Sterling. The weighted average grant date fair value under both of these plans was $11.72 per share, and the restricted stock awards vest in equal annual installments on the anniversary date over a three -year period. The following table summarizes the activity in the Company’s active stock-based compensation plans for the six months ended June 30, 2016 : Non-vested stock awards/stock units outstanding Stock options outstanding Shares available for grant Number of shares Weighted average grant date fair value Number of shares Weighted average exercise price Balance at January 1, 2016 4,125,665 726,800 $ 13.36 1,586,572 $ 10.95 Granted (492,731 ) 492,731 14.21 — — Stock awards vested — (46,167 ) — — — Exercised — — — (165,055 ) 10.76 Forfeited 57,678 (5,531 ) 10.93 (38,261 ) 13.23 Canceled/expired (57,678 ) — — — — Balance at June 30, 2016 3,632,934 1,167,833 $ 14.26 1,383,256 $ 10.91 Exercisable at June 30, 2016 1,013,767 $ 10.20 The total intrinsic value of outstanding in-the-money stock options and outstanding in-the-money exercisable stock options was $6,629 and $5,574 , respectively, at June 30, 2016 .

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders’ Equity (a) Regulatory Capital Requirements Banks and bank holding companies are subject to various regulatory capital requirements administered by the Federal banking agencies. Capital adequacy guidelines, and additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk-weighting, and other factors. The Basel III Capital Rules became effective for the Company and the Bank on January 1, 2015 (subject to a phase-in period for certain provisions). Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table below) of Common Equity Tier 1 capital (as defined in the regulations), Tier 1 capital (as defined in the regulations) and Total capital (as defined in the regulations) to risk-weighted assets (as defined, “RWA”), and of Tier 1 capital to adjusted quarterly average assets (as defined in the regulations) (the “Tier 1 leverage ratio”). The Company’s and the Bank’s Common Equity Tier 1 capital consists of common stock and related paid-in capital, net of treasury stock, and retained earnings. In connection with the adoption of the Basel III Capital Rules, we elected to opt-out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1 capital. Common Equity Tier 1 capital for both the Company and the Bank is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities and subject to transition provisions. Tier 1 capital includes Common Equity Tier 1 capital and additional Tier 1 capital. Total capital includes Tier 1 capital and Tier 2 capital. Tier 2 capital (as defined in the regulations) for both the Bank and the Company includes a permissible portion of the allowance for loan losses and $108,161 and $99,342 of the Subordinated Notes, respectively. During the final five years of the term of the Subordinated Notes the permissible portion eligible for inclusion in Tier 2 capital decreases by 20% annually. See Note 8. “Borrowings.” The Common Equity Tier 1, Tier 1 and Total capital ratios are calculated by dividing the respective capital amounts by RWA. RWA is calculated based on regulatory requirements and includes total assets, excluding goodwill and other intangible assets, allocated by risk weight category, and certain off-balance-sheet items, among other things. The Tier 1 leverage ratio is calculated by dividing Tier 1 capital by adjusted quarterly average total assets, which exclude goodwill and other intangible assets, among other things. When fully phased-in on January 1, 2019, the Basel III Capital Rules will require the Company and the Bank to maintain: (i) a minimum ratio of Common Equity Tier 1 capital to RWA of at least 4.5%, plus a 2.5% “capital conservation buffer” (which is added to the 4.5% Common Equity Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum ratio of Common Equity Tier 1 capital to RWA of at least 7.0% upon full implementation); (ii) a minimum ratio of Tier 1 capital to RWA of at least 6.0%, plus the capital conservation buffer (which is added to the 6.0% Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum Tier 1 capital ratio of 8.5% upon full implementation); (iii) a minimum ratio of Total capital (that is, Tier 1 plus Tier 2) to RWA of at least 8.0%, plus the capital conservation buffer (which is added to the 8.0% total capital ratio as that buffer is phased in, effectively resulting in a minimum total capital ratio of 10.5% upon full implementation); and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to adjusted quarterly average assets. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and is being phased-in over a four-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). The Basel III Capital Rules also provide for a “countercyclical capital buffer” that is applicable to only certain covered institutions and does not have any current applicability to the Company or the Bank. The aforementioned capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of Common Equity Tier 1 capital to RWA above the minimum but below the conservation buffer (or below the combined capital conservation buffer and countercyclical capital buffer, when the latter is applied) will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. The following tables present actual and required capital ratios as of June 30, 2016 and December 31, 2015 for the Company and the Bank under the Basel III Capital Rules. The minimum required capital amounts presented include the minimum required capital levels as of June 30, 2016 and December 31, 2015 based on the phase-in provisions of the Basel III Capital Rules and the minimum required capital levels as of January 1, 2019 when the Basel III Capital Rules have been fully phased-in. Capital levels required to be considered well-capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules.

Regulatory authorities can initiate certain mandatory actions if the Bank or the Company fail to meet the minimum capital requirements, which could have a direct material effect on our financial statements. As of June 30, 2016 , management believes that the Bank and the Company meet all capital adequacy requirements to which they are subject. (b) Dividend Restrictions The Company is mainly dependent upon dividends from the Bank to provide funds for the payment of dividends to stockholders and to provide for other cash requirements. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels. Approval is also required if dividends declared exceed the net profits for that fiscal year combined with the retained net profits for the preceding two fiscal years. Under the foregoing dividend restrictions and while maintaining its “well-capitalized” status, at June 30, 2016 , the Bank had capacity to pay aggregate dividends of up to $90,054 to the Company without prior regulatory approval. (c) Capital Raise On February 11, 2015 , the Company completed a public offering of 6.9 million shares of common stock at an offering price of $13.00 per share for gross proceeds of approximately $ 89,700 , and net proceeds, after underwriting discounts, commissions and other costs of issuance, of $85,059 . (d) Stock Repurchase Plans From time to time, the Company’s Board of Directors has authorized stock repurchase plans. The Company has 776,713 shares that are available to be purchased under a previously announced stock repurchase program. There were no shares repurchased under the repurchase program during the six months ended June 30, 2016 or June 30, 2015 . (e) Liquidation Rights Upon completion of a second-step conversion in January 2004 , the Bank established a special “liquidation account” in accordance with Office of the Comptroller of the Currency regulations. The account was established for the benefit of Eligible Account Holders and Supplemental Eligible Account Holders (as defined in the plan of conversion) in an amount equal to the greater of (i) the Mutual Holding Company’s (as defined in the plan of conversion) ownership interest in the retained earnings of the Bank as of the date of its latest balance sheet contained in the prospectus; or (ii) the retained earnings of the Bank at the time that the Bank reorganized into the Mutual Holding Company in 1999. Each Eligible Account Holder and Supplemental Eligible Account Holder that continues to maintain his or her deposit account at the Bank would be entitled, in the event of a complete liquidation of the Bank, to a pro rata interest in the liquidation account prior to any payment to the stockholders of the Company. The liquidation account is reduced annually on September 30 to the extent that Eligible Account Holders and Supplemental Eligible Account Holders have reduced their qualifying deposits as of each anniversary date. At June 30, 2016 , the liquidation account had a balance of $13,300 . Subsequent increases in deposits do not restore such account holder’s interest in the liquidation account. The Bank may not pay cash dividends or make other capital distributions if the effect thereof would reduce its stockholders’ equity below the amount of the liquidation account. (f) Impact of the HVB Merger On June 30, 2015, the Company completed the HVB Merger. In connection with the HVB Merger, the Company issued 38.5 million common shares to HVHC shareholders, which resulted in an increase of $563,613 in stockholders’ equity.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies (a) Off-Balance Sheet Financial Instruments In the normal course of business, the Company enters into various transactions, which in accordance with GAAP are not included in its consolidated balance sheet. The Company enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company minimizes its exposure to losses under these commitments by subjecting them to credit approval and monitoring procedures. The Company enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of the Company’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding. Standby letters of credit are written conditional commitments issued by the Company to guarantee the performance of a customer to a third-party. In the event the customer does not perform in accordance with the terms of the agreement with the third-party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment were funded, the Company would be entitled to seek recovery from the customer. Based on the Company’s credit risk exposure assessment of its standby letter of credit arrangements, the arrangements contain security and debt covenants similar to those contained in loan agreements. The contractual or notional amounts of these instruments, which reflect the extent of the Company’s involvement in particular classes of off-balance sheet financial instruments, are summarized as follows: June 30, December 31, 2016 2015 Loan origination commitments $ 228,421 $ 269,636 Unused lines of credit 857,008 660,915 Letters of credit 111,787 102,930 (b) Lease Commitments The Company leases certain premises and equipment under operating leases with terms expiring through January 2034. Included in occupancy and office operations expense was net rent expense of $2,422 and $1,728 during the three months ended June 30, 2016 and 2015 , respectively, and net rent expense of $5,721 and $3,305 for the six months ended June 30, 2016 and 2015 , respectively. Future minimum lease payments due under non-cancelable operating leases at June 30, 2016 were as follows: Remainder of 2016 $ 5,541 2017 10,326 2018 9,407 2019 6,848 2020 5,405 2021 5,001 2022 and thereafter 20,319 $ 62,847 (c) Litigation The Company and the Bank are involved in a number of judicial proceedings concerning matters arising from conducting their business activities. These include routine legal proceedings arising in the ordinary course of business. These proceedings also include actions brought against the Company and the Bank with respect to corporate matters and transactions in which the Company and the Bank are or were involved. In addition, the Company and the Bank may be requested to provide information or otherwise cooperate with government authorities in the conduct of investigations of other persons or industry groups. There can be no assurance as to the ultimate outcome of a legal proceeding; however, the Company and the Bank have generally denied liability in all significant litigation pending against them and intend to defend vigorously each case, other than matters that are determined appropriate to be settled. The Company and the Bank accrue a liability for legal claims when payments associated with the claims become probable and the costs can be reasonably estimated. The actual costs of resolving legal claims may be substantially higher or lower than the amounts accrued for those claims.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair value measurements	Fair value measurements Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets and liabilities that the reporting entity has the ability to access at the measurement date. Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risk, etc.) or inputs that are derived principally from, or corroborated by, market data by correlation or other means. Level 3 Inputs – Unobservable inputs for determining the fair value of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. In general, fair value is based on quoted market prices, when available. If quoted market prices in active markets are not available, fair value is based on internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates; therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value is set forth below. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincide with the Company’s monthly and/or quarterly valuation process. Investment Securities Available for Sale The majority of the Company’s available for sale investment securities are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the securities’ terms and conditions, among other things. The Company reviews the prices supplied by the independent pricing service, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. In general, the Company does not purchase investment securities that have a complicated structure. The Company’s entire portfolio consists of traditional investments, nearly all of which are mortgage pass-through securities, state and municipal general obligation or revenue bonds, U.S. agency bullet and callable securities and corporate bonds. Pricing for such instruments is fairly generic and is easily obtained. From time to time, the Company validates, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from third-party sources or derived using internal models. As of June 30, 2016 , we do not believe any of our securities are OTTI; however, we review all of our securities on at least a quarterly basis to assess whether impairment, if any, is OTTI. Derivatives The fair values of derivatives are based on valuation models using current market terms (including interest rates and fees), the remaining terms of the agreements and the creditworthiness of the counterparty as of the measurement date (Level 2 inputs). The Company’s derivatives consist of interest rate swaps. See Note 9. “Derivatives” for additional information. Commitments to Sell Real Estate Loans The Company enters into various commitments to sell real estate loans in the secondary market. Such commitments are considered to be derivative financial instruments and if material, are carried at estimated fair value on the consolidated balance sheets. The estimated fair values of these commitments were generally calculated by reference to quoted prices in secondary markets for commitments to sell to certain government sponsored agencies. The fair values of these commitments generally result in a Level 2 classification and are not material. A summary of assets and liabilities at June 30, 2016 measured at estimated fair value on a recurring basis was as follows: June 30, 2016 Fair value Level 1 inputs Level 2 inputs Level 3 inputs Assets: Investment securities available for sale: Residential MBS (1) : Agency-backed $ 1,215,975 $ — $ 1,215,975 $ — CMO (2) /Other MBS 69,167 — 69,167 — Total residential MBS 1,285,142 — 1,285,142 — Other securities: Federal agencies 83,987 — 83,987 — Corporate 69,783 — 69,783 — State and municipal 165,310 — 165,310 — Other 8,791 — 8,791 — Total other securities 327,871 — 327,871 — Total available for sale securities 1,613,013 — 1,613,013 — Swaps 7,498 — 7,498 — Total assets $ 1,620,511 $ — $ 1,620,511 $ — Liabilities: Swaps $ 7,498 $ — $ 7,498 $ — Total liabilities $ 7,498 $ — $ 7,498 $ — (1) Residential mortgage-backed securities (“MBS”) are debt securities whose cash flows come from residential loans, such as mortgages and home-equity loans. A residential MBS is comprised of a pool of mortgage loans created by financial institutions including governmental agencies. The cash flows from each of the mortgage loans included in the pool are structured through a special purpose entity into various classes and tranches, which then issue securities backed by those cash flows to investors. (2) Collateralized Mortgage Obligations (“CMOs”) are debt securities that are collateralized by a specific pool of residential mortgage loans, in which the issuer of the CMOs can direct the payments of principal and interest received on the underlying collateral to achieve specific investor cash flow objectives. The Bank generally acquires planned-amortization class securities and CMOs with a sequential pay structure in order to manage the duration and extension risk inherent in these securities. A summary of assets and liabilities at December 31, 2015 measured at estimated fair value on a recurring basis was as follows: December 31, 2015 Fair value Level 1 inputs Level 2 inputs Level 3 inputs Assets: Investment securities available for sale: Residential MBS: Agency-backed $ 1,217,862 $ — $ 1,217,862 $ — CMO/Other MBS 78,373 — 78,373 — Total residential MBS 1,296,235 — 1,296,235 — Federal agencies 84,267 — 84,267 — Corporate bonds 314,188 — 314,188 — State and municipal 189,035 — 189,035 — Trust preferred 28,517 — 28,517 — Other 8,790 — 8,790 — Total investment securities available for sale 624,797 — 624,797 — Total available for sale securities 1,921,032 — 1,921,032 — Swaps 1,839 — 1,839 — Total assets $ 1,922,871 $ — $ 1,922,871 $ — Liabilities: Swaps $ 1,839 $ — $ 1,839 $ — Total liabilities $ 1,839 $ — $ 1,839 $ — The following categories of financial assets are not measured at fair value on a recurring basis, but are subject to fair value adjustments in certain circumstances. Loans Held for Sale and Impaired Loans Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value as determined by outstanding commitments from investors. Fair value of loans held for sale is determined using quoted prices for similar assets (Level 2 inputs). When mortgage loans held for sale are sold with servicing rights retained, the carrying value of mortgage loans sold is reduced by the amount allocated to the value of the servicing rights, which is equal to its fair value. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. The Company may record adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of these loans. These adjustments also include certain impairment amounts for collateral dependent loans calculated in accordance with FASB ASC Topic 310 – Receivables when establishing the allowance for loan losses. Impairment amounts are generally based on the fair value of the underlying collateral supporting the loan and, as a result, the carrying value of the loan less the calculated impairment amount applicable to that loan does not necessarily represent the fair value of the loan. Real estate collateral is valued using independent appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable by market participants. However, due to the substantial judgment applied and limited volume of activity as compared to other assets, fair value of the underlying collateral is based on Level 3 inputs. Estimates of fair value used for collateral supporting commercial loans generally are based on assumptions not observable in the market place and are also based on Level 3 inputs. Impaired loans are evaluated on at least a quarterly basis for additional impairment and their carrying values are adjusted as needed. Loans subject to non-recurring fair value measurements were $56,954 and $28,372 at June 30, 2016 and December 31, 2015, respectively. Changes in fair value recognized as a charge-off on loans held by the Company were $0 and $280 for the six months ended June 30, 2016 and 2015 , respectively. When valuing impaired loans that are collateral dependent, the Company charges-off the difference between the recorded investment in the loan and the appraised value, which is generally less than 12 months old. A discount for estimated costs to dispose of the asset is used when evaluating the impaired loans. A summary of the two classes with impaired loans at June 30, 2016 measured at estimated fair value on a non-recurring basis was the following: June 30, 2016 Fair value Level 1 inputs Level 2 inputs Level 3 inputs Commercial real estate 5,065 — — 5,065 Total impaired loans measured at fair value $ 5,065 $ — $ — $ 5,065 A summary of the class of impaired loans at December 31, 2015 measured at estimated fair value on a non-recurring basis was the following: December 31, 2015 Fair value Level 1 inputs Level 2 inputs Level 3 inputs Commercial real estate $ 3,218 $ — $ — $ 3,218 Total impaired loans measured at fair value $ 3,218 $ — $ — $ 3,218 Mortgage Servicing Rights When mortgage loans are sold with servicing retained, servicing rights are initially recorded at fair value with the income statement effect recorded in net gain on sales of loans. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The Company utilizes the amortization method to subsequently measure the carrying value of its servicing rights. In accordance with FASB ASC Topic 860 - Transfers and Servicing, the Company must record impairment charges on a non-recurring basis, when the carrying value exceeds the estimated fair value. To estimate the fair value of servicing rights, the Company utilizes a third-party valuation provider which, on a quarterly basis, considers the market prices for similar assets and the present value of expected future cash flows associated with the servicing rights. Assumptions utilized include estimates of the cost of servicing, loan default rates, an appropriate discount rate and prepayment speeds. The determination of fair value of servicing rights relies upon Level 3 inputs. The fair value of mortgage servicing rights at June 30, 2016 and December 31, 2015 were $1,064 and $1,204 , respectively. Assets Taken in Foreclosure of Defaulted Loans Assets taken in foreclosure of defaulted loans are initially recorded at fair value less costs to sell when acquired, which establishes a new cost basis. These assets are subsequently accounted for at the lower of cost or fair value less costs to sell and are primarily comprised of commercial and residential real estate property and, upon initial recognition, are re-measured and reported at fair value through a charge-off to the allowance for loan losses based on the fair value of the foreclosed asset. The fair value is generally determined using appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace. Adjustments are routinely made in the appraisal process by independent appraisers to adjust for differences between comparable sales and income data available. The fair value is derived using Level 3 inputs. Appraisals are reviewed by the Company’s credit department, external loan review consultant and verified by officers in the Company’s credit administration area. Assets taken in foreclosure of defaulted loans and facilities held for sale subject to non-recurring fair value measurement were $16,590 and $14,614 at June 30, 2016 and December 31, 2015 , respectively. There were $582 and $0 of write-downs related to changes in fair value for those foreclosed assets held by the Company during the six months ended June 30, 2016 and June 30, 2015 , respectively. Significant Unobservable Inputs to Level 3 Measurements The following table presents quantitative information about significant unobservable inputs used in the fair value measurements for Level 3 assets at June 30, 2016 : Non-recurring fair value measurements Fair value Valuation technique Unobservable input / assumptions Range (1) (weighted average) Impaired loans: Commercial real estate 5,065 Appraisal Adjustments for comparable properties 22.0% (22.0%) Assets taken in foreclosure: Residential mortgage 5,227 Appraisal Adjustments by management to reflect current conditions/selling costs 10.0% - 22.0% (21.6%) Commercial real estate (2) 6,564 Appraisal Adjustments by management to reflect current conditions/selling costs 10.0% - 22.0% (22.0%) ADC 4,312 Appraisal Adjustments by management to reflect current conditions/selling costs 10.0% - 22.0% (22.0%) Mortgage servicing rights 1,064 Discounted cash flow Discount rates 8.5% - 11.5% (9.7%) Discounted cash flow Prepayment speeds 100 - 2086 (203) (1) Represents range of discount factors applied to the appraisal to determine fair value. The amounts used for mortgage servicing rights are discounts applied by a third-party valuation provider, which the Company believes are appropriate. (2) Excludes $487 of commercial properties that are former financial centers that were closed and are now held for sale. These assets were not taken in foreclosure and their fair value is determined by third-party appraisals and our internal assessment of the market for this type of real estate. Fair Values of Financial Instruments FASB Codification Topic 825 - Financial Instruments requires disclosure of fair value information for those financial instruments for which it is practicable to estimate fair value, whether or not such financial instruments are recognized in the consolidated financial statements for interim and annual periods. Fair value is the amount for which a financial instrument could be exchanged in a current transaction between willing parties, other than in a forced sale or liquidation. Quoted market prices are used to estimate fair values when those prices are available, although active markets do not exist for many types of financial instruments. Fair values for these instruments must be estimated by management using techniques such as discounted cash flow analysis and comparison to similar instruments. These estimates are highly subjective and require judgments regarding significant matters, such as the amount and timing of future cash flows and the selection of discount rates that appropriately reflect market and credit risks. Changes in these judgments often have a material effect on the fair value estimates. Since these estimates are made as of a specific point in time, they are susceptible to material near-term changes. Fair values disclosed in accordance with FASB Topic 825 do not reflect any premium or discount that could result from the sale of a large volume of a particular financial instrument, nor do they reflect possible tax ramifications or estimated transaction costs. The following is a summary of the carrying amounts and estimated fair value of financial assets and liabilities (none of which were held for trading purposes) as of June 30, 2016 : June 30, 2016 Carrying amount Level 1 inputs Level 2 inputs Level 3 inputs Financial assets: Cash and cash equivalents $ 258,326 $ 258,326 $ — $ — Securities available for sale 1,613,013 — 1,613,013 — Securities held to maturity 1,367,046 — 1,413,618 — Portfolio loans, net 8,538,430 — — 8,595,755 Loans held for sale 57,249 — 57,249 — Accrued interest receivable on securities 13,493 — 13,493 — Accrued interest receivable on loans 21,613 — — 21,613 FHLB stock and FRB stock 102,855 — — — Swaps 7,498 — 7,498 — Financial liabilities: Non-maturity deposits (9,197,769 ) (9,197,769 ) — — Certificates of deposit (587,787 ) — (588,713 ) — FHLB borrowings (1,074,492 ) — (1,077,180 ) — Other borrowings (28,202 ) — (28,196 ) — Senior notes (99,099 ) — (103,826 ) — Subordinated notes (108,161 ) — (111,562 ) — Mortgage escrow funds (14,283 ) — (14,279 ) — Accrued interest payable on deposits (595 ) — (595 ) — Accrued interest payable on borrowings (5,149 ) — (5,149 ) — Swaps (7,498 ) — (7,498 ) — The following is a summary of the carrying amounts and estimated fair value of financial assets and liabilities (none of which were held for trading purposes) as of December 31, 2015 : December 31, 2015 Carrying amount Level 1 inputs Level 2 inputs Level 3 inputs Financial assets: Cash and cash equivalents $ 229,513 $ 229,513 $ — $ — Securities available for sale 1,921,032 — 1,921,032 — Securities held to maturity 722,791 — 734,079 — Portfolio loans, net 7,809,215 — — 7,876,064 Loans held for sale 34,110 — 34,110 — Accrued interest receivable on securities 11,329 — 11,329 — Accrued interest receivable on loans 20,202 — — 20,202 FHLB stock and FRB stock 116,758 — — — Swaps 1,839 — 1,839 — Financial liabilities: Non-maturity deposits (7,974,817 ) (7,974,817 ) — — Certificates of deposit (605,190 ) — (603,634 ) — FHLB borrowings (1,409,885 ) — (1,418,155 ) — Other borrowings (16,566 ) — (16,430 ) — Senior notes (98,893 ) — (105,088 ) — Mortgage escrow funds (13,778 ) — (13,775 ) — Accrued interest payable on deposits (783 ) — (783 ) — Accrued interest payable on borrowings (4,490 ) — (4,490 ) — Swaps (1,839 ) — (1,839 ) — The following paragraphs summarize the principal methods and assumptions used by the Company to estimate the fair value of the Company’s financial instruments: Loans The estimated fair value approximates the carrying value for variable-rate loans that reprice frequently and with no significant change in credit risk. The fair value of fixed-rate loans and variable-rate loans which reprice on an infrequent basis is estimated by discounting future cash flows using the current interest rates at which similar loans with similar terms would be made to borrowers of similar credit quality. An overall valuation adjustment is made for specific credit risks, as well as general portfolio credit risk. FHLB Stock and FRB Stock The redeemable carrying amount of these securities with limited marketability approximates their fair value. Deposits and Mortgage Escrow Funds In accordance with FASB Codification Topic 825 - Financial Instruments , deposits with no stated maturity (such as demand, money market and savings deposits) are assigned fair values equal to the carrying amounts payable on demand. Certificates of deposit and mortgage escrow funds are segregated by account type and original term, and fair values are estimated by discounting the contractual cash flows. The discount rate for each account grouping is equivalent to the current market rates for deposits of similar type and maturity. These fair values do not include the value of core deposit relationships that comprise a significant portion of the Company’s deposits. We believe that the Company’s core deposit relationships provide a relatively stable, low-cost funding source that has a substantial value separate from the deposit balances. FHLB Borrowings, Other borrowings, Senior notes and Subordinated notes The estimated fair value approximates the carrying value for short-term borrowings. The fair value of long-term fixed-rate borrowings is estimated using quoted market prices, if available, or by discounting future cash flows using current interest rates for similar financial instruments. Other Financial Instruments Other financial assets and liabilities listed in the table above have estimated fair values that approximate their respective carrying amounts because the instruments are payable on demand or have short-term maturities and present relatively low credit risk and interest rate risk. The fair values of the Company’s off-balance sheet financial instruments described in the “Off-Balance Sheet Financial Instruments” section of Note 16. “Commitments and Contingencies” were estimated based on current market terms (including interest rates and fees), considering the remaining terms of the agreements and the creditworthiness of the counterparties. At June 30, 2016 and December 31, 2015 , the estimated fair value of these instruments approximated the related carrying amounts, which were not material. Accrued Interest Receivable/Payable The carrying amounts of accrued interest approximate fair value and are classified in accordance with the related instrument.

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Standards Not Yet Adopted	Recently Issued Accounting Standards Not Yet Adopted Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 implements a revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 was originally going to be effective for the Company on January 1, 2017; however, the FASB subsequently issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606) - Deferral of the Effective Date,” which deferred the effective date of ASU 2014-09 by one year to January 1, 2018. The Company is currently evaluating the potential impact of ASU 2014-09 on its consolidated financial statements. ASU 2016-1, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-1, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (viii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale. ASU 2016-1 will be effective for the Company on January 1, 2018 and is not expected to have a significant impact on its financial statements. ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 will, among other things, require lessees to recognize a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, “Revenue from Contracts with Customers.” ASU 2016-2 will be effective for us on January 1, 2019 and will require transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company is currently evaluating the potential impact of ASU 2016-02 on its financial statements and its regulatory capital ratios. ASU 2016-05, “Derivatives and Hedging (Topic 815) Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships.” ASU 2016-05 clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under ASC Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. ASU 2016-05 will be effective for the Company on January 1, 2017 and is not expected to have a significant impact on its financial statements. ASU 2016-07, “Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting.” ASU 2016-07 impacts all entities that have an investment that becomes qualified for the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence. ASU 2016-07 simplifies the transition to the equity method of accounting by eliminating retroactive adjustment of the investment when an investment qualifies for use of the equity method, among other things. ASU 2016-07 will be effective for the Company on January 1, 2017 and is not expected to have a significant impact on its financial statements. ASU 2016-08, ”Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net).” ASU 2016-08 was issued to clarify certain principal versus agent considerations within the implementation guidance of ASC Topic 606, “Revenue from Contracts with Customers.” The effective date and transition of ASU 2016-08 is the same as the effective date and transition of ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” as discussed above. The Company is currently evaluating the potential impact of ASU 2016-08 on its financial statements. ASU 2016-09, ”Compensation - Stock compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” Under ASU 2016-09, all excess tax benefits and tax deficiencies related to share-based payment awards should be recognized as income tax expense or benefit in the income statement during the period in which they occur. Previously, such amounts were recorded in the pool of excess tax benefits included in additional paid-in capital, if such pool was available. Because excess tax benefits are no longer recognized in additional paid-in capital, the assumed proceeds from applying the treasury stock method when computing earnings per share should exclude the amount of excess tax benefits that would have previously been recognized in additional paid-in capital. Additionally, excess tax benefits should be classified, along with other income tax cash flows, as an operating activity rather than a financing activity, as was previously the case. ASU 2016-09 also provides that an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (current GAAP) or account for forfeitures when they occur. ASU 2016-09 changes the threshold to qualify for equity classification (rather than as a liability) to permit withholding up to the maximum statutory tax rates (rather than the minimum as was previously the case) in the applicable jurisdictions. ASU 2016-09 will be effective on January 1, 2017 and is not expected to have a significant impact on the Company’s financial statements. ASU No. 2016-10, ”Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” ASU 2016-10 was issued to clarify ASC Topic 606, “Revenue from Contracts with Customers” related to (i) identifying performance obligations; and (ii) the licensing implementation guidance. The effective date and transition of ASU 2016-10 is the same as the effective date and transition of ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” as discussed above. The Company is currently evaluating the potential impact of ASU 2016-10 on its financial statements. ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 will be effective on January 1, 2020. The Company is currently evaluating the potential impact of ASU 2016-13 on its financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements in this Quarterly Report on Form 10-Q include the accounts of the Company and all other entities in which the Company has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. The accounting and financial reporting policies the Company follows conform, in all material respects, to accounting principles generally accepted in the United States (“GAAP”) and to general practices within the banking industry, which includes regulatory reporting instructions. The consolidated financial statements in this Quarterly Report on Form 10-Q have not been audited by an independent registered public accounting firm, but, in the opinion of management, reflect all adjustments necessary for a fair presentation of the Company’s financial position and results of operations. All such adjustments were of a normal and recurring nature. The consolidated financial statements have been prepared in accordance with GAAP and with the instructions to Form 10-Q adopted by the Securities and Exchange Commission (the “SEC”). Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our consolidated financial statements, and notes thereto, for the year ended December 31, 2015 , included in our Annual Report on Form 10-K filed with the SEC on February 29, 2016 (the “2015 Form 10-K”). Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period. Certain items in prior financial statements have been reclassified to conform to the current presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income, expense and contingencies at the date of the financial statements. Actual results could differ significantly from these estimates. The allowance for loan losses and the status of contingencies are particularly subject to change.

A residential MBS is comprised of a pool of mortgage loans created by financial institutions including governmental agencies. The cash flows from each of the mortgage loans included in the pool are structured through a special purpose entity into various classes and tranches, which then issue securities backed by those cash flows to investors. (2) Collateralized Mortgage Obligations (“CMOs”) are debt securities that are collateralized by a specific pool of residential mortgage loans, in which the issuer of the CMOs can direct the payments of principal and interest received on the underlying collateral to achieve specific investor cash flow objectives. The Bank generally acquires planned-amortization class securities and CMOs with a sequential pay structure in order to manage the duration and extension risk inherent in these securities.
