	Note 1 Basis of Presentation and Summary of Significant Accounting Policies



	BankUnited, Inc. (“BankUnited, Inc.” or “BKU”), is a national bank holding company with one wholly-owned subsidiary, BankUnited, National Association (“BankUnited” or the “Bank”), collectively, the Company. BankUnited, a national banking association headquartered in Miami Lakes, Florida, provides a full range of banking and related services to individual and corporate customers through 99 branches located in 15 Florida counties and 6 banking centers located in the New York metropolitan area at March 31, 2014.



	On May 21, 2009, BankUnited acquired substantially all of the assets and assumed all of the non-brokered deposits and substantially all of the other liabilities of BankUnited, FSB from the Federal Deposit Insurance Corporation (“FDIC”) in a transaction referred to as the “FSB Acquisition.” Neither the Company nor the Bank had any substantive operations prior to May 21, 2009. In connection with the FSB Acquisition, BankUnited entered into two loss sharing agreements with the FDIC (the “Loss Sharing Agreements”). The Loss Sharing Agreements consist of a single family shared-loss agreement (the “Single Family Shared-Loss Agreement”), and a commercial and other loans shared-loss agreement, (the “Commercial Shared-Loss Agreement”). The Single Family Shared-Loss Agreement provides for FDIC loss sharing and the Bank’s reimbursement for recoveries to the FDIC through May 21, 2019 for single family residential loans and other real estate owned (“OREO”). The Commercial Shared-Loss Agreement provides for FDIC loss sharing through May 21, 2014 and the Bank’s reimbursement for recoveries to the FDIC through May 21, 2017 for all other covered assets, including commercial real estate, commercial and industrial and consumer loans, certain investment securities and commercial OREO. The assets covered under the Loss Sharing Agreements are collectively referred to as the “covered assets.” Pursuant to the terms of the Loss Sharing Agreements, the covered assets are subject to a stated loss threshold whereby the FDIC will reimburse BankUnited for 80% of losses related to the covered assets up to $4.0 billion and 95% of losses in excess of this amount, beginning with the first dollar of loss incurred.



	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required for a fair presentation of financial position, results of operations and cash flows in conformity with U.S. generally accepted accounting principles (“GAAP”) and should be read in conjunction with the Company’s consolidated financial statements and the notes thereto appearing in BKU’s Annual Report on Form 10-K for the year ended December 31, 2013 filed with the SEC. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected in future periods.



	Certain amounts presented for prior periods have been reclassified to conform to the current period presentation.



	Accounting Estimates



	In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and disclosures of contingent assets and liabilities. Actual results could differ significantly from these estimates.



	Significant estimates include the allowance for loan and lease losses, the amount and timing of expected cash flows from covered assets and the FDIC indemnification asset, the fair values of investment securities and other financial instruments and the valuation of OREO. Management has used information provided by third party valuation specialists to assist in the determination of the fair values of investment securities and OREO.

The Company monitors its investment securities available for sale for other-than-temporary impairment (“OTTI”) on an individual security basis. No securities were determined to be other than temporarily impaired at March 31, 2014 and 2013. The Company does not intend to sell securities that are in significant unrealized loss positions and it is not more likely than not that the Company will be required to sell these securities before recovery of the amortized cost basis, which may be at maturity. At March 31, 2014, 36 securities were in unrealized loss positions. Unrealized losses on investment securities available for sale at March 31, 2014 were primarily attributable to an increase in medium and long-term market interest rates subsequent to the date the securities were acquired. The amount of impairment related to 12 of these securities was considered insignificant, totaling approximately $155 thousand and no further analysis with respect to these securities was considered necessary. The basis for concluding that impairment of the remaining securities was not other-than-temporary is further described below:

U.S. Government agency and sponsored enterprise residential and commercial mortgage-backed securities:

At March 31, 2014, nine U.S. Government agency and sponsored enterprise residential and commercial mortgage-backed securities were in unrealized loss positions. All of these securities were in unrealized loss positions for less than 12 months. These securities evidenced unrealized losses ranging from 1% to 8% of amortized cost. The timely payment of principal and interest on these securities is explicitly or implicitly guaranteed by the U.S. Government. Given the limited severity and duration of impairment and the expectation of timely payment of principal and interest, the impairments were considered to be temporary.

Private label residential mortgage-backed securities and CMOs:

At March 31, 2014, five private label residential mortgage-backed securities were in unrealized loss positions. These securities were assessed for OTTI using third-party developed credit and prepayment behavioral models and CUSIP level constant default rates, voluntary prepayment rates and loss severity and delinquency assumptions. The results of these assessments were not indicative of credit losses related to any of these securities as of March 31, 2014. Three of these securities were in unrealized loss positions for less than twelve months and one for 13 months. These securities evidenced unrealized losses ranging from 1% to 6% of amortized cost. The remaining security had been in an unrealized loss position for 33 months and the unrealized loss of $74 thousand amounted to 7% of amortized cost. The market for this security is thin and the market price is adversely affected by lack of liquidity. This bond is considered an odd lot which can be detrimental to potential bids for the security. Given the generally limited duration and severity of impairment and the expectation of timely recovery of outstanding principal, the impairments were considered to be temporary.

Private label commercial mortgage-backed securities:

At March 31, 2014, nine private label commercial mortgage-backed securities were in unrealized loss positions. Eight of these securities were in unrealized loss positions for less than twelve months and one for 15 months. The amount of impairment ranged from less than 1% to 4% of amortized cost. These securities were assessed for OTTI using third-party developed models, incorporating assumptions consistent with the collateral characteristics of each security. The results of this analysis were not indicative of expected credit losses. Securities in this class generally have longer durations than the portfolio as a whole, so are more significantly impacted by changes in rates. Given the limited severity and duration of impairment and the expectation of timely recovery of outstanding principal, the impairments were considered to be temporary.

Non-mortgage asset-backed securities:

At March 31, 2014, one non-mortgage asset-backed security was in an unrealized loss position. This security had been in an unrealized loss position for less than 3 months and the amount of impairment was less than 1% of amortized cost. This security was assessed for OTTI using a third-party developed credit and prepayment behavioral model and CUSIP level constant default rates, voluntary prepayment rates and loss severity and delinquency assumptions. The results of this analysis were not indicative of expected credit losses. Given the limited severity and duration of impairment and the expectation of timely recovery of outstanding principal, the impairment was considered to be temporary.

	Note 4 Loans and Allowance for Loan and Lease Losses

	A significant portion of the Company’s loan portfolio consists of loans acquired in the FSB Acquisition. Substantially all of these loans are covered under BankUnited’s Loss Sharing Agreements (the “covered loans”). Loans originated or purchased since the FSB Acquisition (“new loans”) are not covered by the Loss Sharing Agreements. Loans acquired in the FSB Acquisition may be further segregated between those acquired with evidence of deterioration in credit quality since origination (“Acquired Credit Impaired” or “ACI” loans) and those acquired without evidence of deterioration in credit quality since origination (“non-ACI” loans).

	At March 31, 2014 and December 31, 2013, the unpaid principal balance (“UPB”) of ACI loans was $3.1 billion and $3.3 billion, respectively.

	During the three months ended March 31, 2014 and 2013, the Company purchased 1-4 single family residential loans totaling $179 million and $227 million, respectively.

	At March 31, 2014, the Company had pledged real estate loans with UPB of approximately $6.5 billion and recorded investment of approximately $4.7 billion as security for FHLB advances.

	Covered loan sales

	During the periods indicated, the Company sold covered 1-4 single family residential loans to third parties on a non-recourse basis. The following table summarizes the impact of these transactions (in thousands):

			Three Months Ended March 31,

Covered 1-4 single family residential loans with UPB of $16 million and $20 million, respectively, were sold from a pool of ACI loans with a zero carrying value. Proceeds of the sale of loans from this pool, representing realization of accretable yield, were recorded in interest income. The loss on the sale of loans from the remaining pools, representing the difference between the recorded investment and consideration received, was recorded in “Gain (loss) on sale of loans, net” in the accompanying consolidated statements of income.

During the three months ended March 31, 2014, in accordance with the terms of the Commercial Shared-Loss Agreement, the Bank requested and received approval from the FDIC to sell certain covered commercial and consumer loans. These loans were transferred to loans held for sale at the lower of carrying value or fair value, determined at the individual loan level, upon receipt of FDIC approval and sold in March 2014. The reduction of carrying value to fair value for specific loans was recognized in the provision for loan losses. The following table summarizes the pre-tax impact of these sales, as reflected in the consolidated statements of income for the three months ended March 31, 2014 (in thousands):

Cash proceeds, net of transaction costs		$	101,023

New and non-ACI loans contractually delinquent by 90 days or more and still accruing totaled $1.2 million and $0.5 million at March 31, 2014 and December 31, 2013, respectively. The amount of additional interest income that would have been recognized on non-accrual loans and TDRs had they performed in accordance with their contractual terms is not material.

The following table summarizes new and non-ACI loans that were modified in TDRs during the periods indicated, as well as new and non-ACI loans modified during the twelve months preceding March 31, 2014 and 2013, that experienced payment defaults during the periods indicated (dollars in thousands):

Modifications during the three months ended March 31, 2014 and 2013 included restructuring of the amount and timing of required periodic payments, extensions of maturity and residential modifications under the U.S. Treasury Department’s Home Affordable Modification Program (“HAMP”). Included in TDRs are loans to consumer borrowers who have not reaffirmed their debt discharged in Chapter 7 bankruptcy. The total amount of such loans is not material. Because of the immateriality of the amount of loans modified in TDRs and nature of the modifications, the modifications did not have a material impact on the Company’s consolidated financial statements or on the determination of the amount of the ALLL atMarch 31, 2014 and 2013.

Management considers delinquency status to be the most meaningful indicator of the credit quality of 1-4 single family residential, home equity and consumer loans. Delinquency statistics are updated at least monthly. Original loan to value (“LTV”) ratio and original FICO score are also important indicators of credit quality for the new 1-4 single family residential portfolio, while original FICO score is an important indicator of credit quality for the indirect auto portfolio.

Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Internal risk ratings are a key factor in identifying loans that are individually evaluated for impairment and impact management’s estimates of loss factors used in determining the amount of the ALLL. Internal risk ratings are updated on a continuous basis. Relationships with balances in excess of $1 million are re-evaluated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. Loans exhibiting potential credit weaknesses that deserve management’s close attention and that if left uncorrected may result in deterioration of the repayment capacity of the borrower are categorized as special mention. Loans with well-defined credit weaknesses, including payment defaults, declining collateral values, frequent overdrafts, operating losses, increasing balance sheet leverage, inadequate cash flow, project cost overruns, unreasonable construction delays, past due real estate taxes or exhausted interest reserves, are assigned an internal risk rating of substandard. A loan with a weakness so severe that collection in full is highly questionable or improbable will be assigned an internal risk rating of doubtful.

ACI Loans

The accretable yield on ACI loans represents the amount by which undiscounted expected future cash flows exceed recorded investment. Changes in the accretable yield on ACI loans for the three months ended March 31, 2014 and the year ended December 31, 2013 were as follows (in thousands):

Balance, December 31, 2012		$	1,286,066
Reclassifications from non-accretable difference		282,952
Accretion		(410,446		)
Balance, December 31, 2013		1,158,572
Reclassifications from non-accretable difference		40,617
Accretion		(91,530		)
Balance, March 31, 2014		$	1,107,659

Accretable yield at March 31, 2014 included expected cash flows from a pool of 1-4 single family residential loans whose carrying value had been reduced to zero. The UPB of loans remaining in this pool was $45 million at March 31, 2014.

Credit quality information — ACI loans

ACI loans or loan pools are considered to be impaired when there has been further deterioration in the cash flows expected at acquisition plus any additional cash flows expected to be collected arising from changes in estimates after acquisition, other than due to decreases in interest rate indices and changes in prepayment assumptions. Discount continues to be accreted on ACI loans or pools as long as there are expected future cash flows in excess of the current carrying amount; therefore, these loans are not classified as non-accrual even though they may be contractually delinquent. ACI 1-4 single family residential and home equity loans accounted for in pools are evaluated for impairment on a pool basis and the amount of any impairment is measured based on the expected aggregate cash flows of the pools. ACI commercial and commercial real estate loans are evaluated individually for impairment.

There were no impaired ACI loans or pools at March 31, 2014. The table below sets forth at December 31, 2013, the recorded investment in ACI loans or pools for which the Company has determined it is probable that it will be unable to collect all the cash flows expected at acquisition plus additional cash flows expected to be collected arising from changes in estimates after acquisition, if any, as well as ACI loans not accounted for in pools that have been modified in TDRs, and the related allowance amounts (in thousands):

FDIC Indemnification Asset	'
	Note 5 FDIC Indemnification Asset

	When the Company recognizes gains or losses related to covered assets in its consolidated financial statements, changes in the estimated amount recoverable from the FDIC under the Loss Sharing Agreements with respect to those gains or losses are also reflected in the consolidated financial statements. Covered loans may be resolved through prepayment, short sale of the underlying collateral, foreclosure, sale of the loans or charge-off. For loans resolved through prepayment, short sale or foreclosure, the difference between consideration received in satisfaction of the loans and the carrying value of the loans is recognized in the statement of income line item “Income from resolution of covered assets, net.” Losses from the resolution of covered loans increase the amount recoverable from the FDIC under the Loss Sharing Agreements. Gains from the resolution of covered loans reduce the amount recoverable from the FDIC under the Loss Sharing Agreements. Similarly, differences in proceeds received on the sale of OREO and covered loans and their carrying amounts result in gains or losses and reduce or increase the amount recoverable from the FDIC under the Loss Sharing Agreements. Increases in valuation allowances or impairment charges related to covered assets also increase the amount estimated to be recoverable from the FDIC. These additions to or reductions in amounts recoverable from the FDIC related to the resolution of covered assets are recorded in the consolidated statement of income line item “Net loss on indemnification asset” and reflected as corresponding increases or decreases in the FDIC indemnification asset.

	The following tables summarize the components of the gains and losses associated with covered assets, along with the related additions to or reductions in the amounts recoverable from the FDIC under the Loss Sharing Agreements, as reflected in the consolidated statements of income for the periods indicated (in thousands):

	Loss on covered OREO	(249		)	198			(51		)
		$	13,369		$	(11,687	)	$	1,682

	For a number of reasons, the gain or loss on indemnification asset does not bear the relationship to net gain or loss on sale of covered loans that might generally be expected based on the Loss Sharing Agreements. These reasons include, but are not limited to, the fact that the amount of indemnification from sales of covered loans is generally based on the unpaid principal balance of the loans rather than carrying value and prior charge offs taken on loans sold for which loss share claims were previously submitted.

	Changes in the FDIC indemnification asset for the three months ended March 31, 2014 and for the year ended December 31, 2013, were as follows (in thousands):

	Balance, December 31, 2012	$	1,457,570
	Amortization	(36,943		)
	Reduction for claims filed	(164,872		)
	Net loss on indemnification asset	(50,638		)
	Balance, December 31, 2013	1,205,117

	Net loss on indemnification asset	(16,904		)
	Balance, March 31, 2014	$	1,131,424

	Under the terms of the Loss Sharing Agreements, the Company is also entitled to reimbursement from the FDIC for certain expenses related to covered assets upon final resolution of those assets. For the three months ended March 31, 2014 and 2013, non-interest expense includes $0.7 million and $1.4 million, respectively, of expenses subject to reimbursement at the 80% level under the Loss Sharing Agreements. For those same periods, claims of $1.1 million and $2.9 million, respectively, were submitted to the FDIC for reimbursement. As of March 31, 2014, $12.2 million of expenses incurred to date remained to be submitted for reimbursement from the FDIC in future periods as the related covered assets are resolved.

	The Company’s effective income tax rate of 35.6% for the three months ended March 31, 2014 differed from the statutory federal income tax rate primarily due to the impact of state income taxes, substantially offset by the impact of tax-exempt income and state tax law changes enacted in the first quarter of 2014. For the three months ended March 31, 2013, the effective income tax rate of 39.1% differed from the statutory federal income tax rate primarily due to the impact of state income taxes.

	Note 7 Derivatives and Hedging Activities

	The Company uses interest rate swaps to manage interest rate risk related to variable rate FHLB advances and certificates of deposit with maturities of one year, which expose the Company to variability in cash flows due to changes in interest rates. The Company enters into LIBOR-based interest rate swaps that are designated as cash flow hedges with the objective of limiting the variability of interest payment cash flows resulting from changes in the benchmark interest rate LIBOR. The effective portion of changes in the fair value of interest rate swaps designated as cash flow hedging instruments is reported in accumulated other comprehensive income (“AOCI”) and subsequently reclassified into interest expense in the same period in which the related interest on the floating-rate debt obligations affects earnings.

	The Company also enters into interest rate derivative contracts with certain of its commercial borrowers to enable those borrowers to manage their exposure to interest rate fluctuations. To mitigate interest rate risk associated with these derivative contracts, the Company enters into offsetting derivative contract positions with primary dealers. These interest rate derivative contracts are not designated as hedging instruments; therefore, changes in the fair value of these derivatives are recognized immediately in earnings. The impact on earnings related to changes in fair value of these derivatives for the three months ended March 31, 2014 and 2013 was not material.

	The Company may be exposed to credit risk in the event of non-performance by the counterparties to its interest rate derivative agreements. The Company assesses the credit risk of its financial institution counterparties by monitoring publicly available credit rating and financial information. The Company manages dealer credit risk by entering into interest rate derivatives only with primary and highly rated counterparties, the use of ISDA master agreements and counterparty limits. The agreements contain bilateral collateral arrangements with the amount of collateral to be posted generally governed by the settlement value of outstanding swaps. The Company manages the risk of default by its borrower counterparties through its normal loan underwriting and credit monitoring policies and procedures. The Company does not currently anticipate any losses from failure of interest rate derivative counterparties to honor their obligations.

	The following tables set forth certain information concerning the Company’s interest rate contract derivative financial instruments and related hedged items at the dates indicated (dollars in thousands):

	During the three months ended March 31, 2014 and 2013, no derivative positions designated as cash flow hedges were discontinued and none of the gains and losses reported in AOCI were reclassified into earnings as a result of the discontinuance of cash flow hedges or because of the early extinguishment of debt. As of March 31, 2014, the amount expected to be reclassified from AOCI into income during the next twelve months is $25.9 million.

	Some of the Company’s ISDA master agreements with financial institution counterparties contain provisions that permit either counterparty to terminate the agreements and require settlement in the event that regulatory capital ratios fall below certain designated thresholds, upon the initiation of other defined regulatory actions or upon suspension or withdrawal of the Bank’s credit rating. Currently, there are no circumstances that would trigger these provisions of the agreements.

The difference between the amounts reported for interest rate swaps subject to master netting agreements and the total fair value of interest rate contract derivative financial instruments reported in the consolidated balance sheets is related to interest rate contracts entered into with borrowers not subject to master netting agreements.

At March 31, 2014, the Company has pledged investment securities available for sale with a carrying amount of $41.3 million and cash on deposit of $12.6 million as collateral for these interest rate swaps in a liability position. Financial collateral of $10.0 million was pledged by counterparties to the Company for interest rate swaps in an asset position. The amount of collateral required to be posted by the Company varies based on the settlement value of outstanding swaps and in some cases may include initial margin requirements.

The Company enters into commitments to fund residential mortgage loans with the intention that these loans will subsequently be sold into the secondary market. A mortgage loan commitment binds the Company to lend funds to a potential borrower at a specified interest rate within a specified period of time, generally 30 to 90 days. These commitments are considered derivative instruments. The notional amount of outstanding mortgage loan commitment derivatives was $4 million and $3 million at March 31, 2014 and December 31, 2013, respectively. Outstanding derivative loan commitments expose the Company to the risk that the price of the loans arising from exercise of the commitments might decline from inception of the commitment to funding of the loan. To protect against the price risk inherent in derivative loan commitments, the Company utilizes “best efforts” forward loan sale commitments. Under a “best efforts” contract, the Company commits to deliver an individual mortgage loan to an investor if the loan to the underlying borrower closes. Generally, the price the investor will pay the Company for a loan is specified prior to the loan being funded. These commitments are considered derivative instruments once the underlying loans are funded. The notional amount of forward loan sale commitment derivatives was $1.4 million and $0.2 million at March 31, 2014 and December 31, 2013, respectively. The fair value of loan commitment and forward sale commitment derivatives was nominal at March 31, 2014 and December 31, 2013.

	Assets and liabilities measured at fair value on a recurring basis

	Following is a description of the methodologies used to estimate the fair values of assets and liabilities measured at fair value on a recurring basis and the level within the fair value hierarchy in which those measurements are typically classified.

	Investment securities available for sale—Fair value measurements are based on quoted prices in active markets when available; these measurements are classified within level 1 of the fair value hierarchy. These securities typically include certain preferred stocks and mutual funds. If quoted prices in active markets are not available, fair values are estimated using quoted prices of securities with similar characteristics, quoted prices of identical securities in less active markets, discounted cash flow techniques, or matrix pricing models. These securities are generally classified within level 2 of the fair value hierarchy and include U.S. Government agency securities, U.S. Government agency and sponsored enterprise mortgage-backed securities, preferred stock investments for which level 1 valuations are not available, corporate debt securities, non-mortgage asset-backed securities, certain private label residential mortgage-backed securities and CMOs, Re-Remics, private label commercial mortgage-backed securities and state and municipal obligations. Pricing of these securities is generally primarily spread driven. Observable inputs that may impact the valuation of these securities include benchmark yield curves, credit spreads, reported trades, dealer quotes, bids, issuer spreads, current rating, historical constant prepayment rates, historical voluntary prepayment rates, structural and waterfall features of individual securities, published collateral data, and for certain securities, historical constant default rates and default severities. Investment securities available for sale generally classified within level 3 of the fair value hierarchy include certain private label mortgage-backed securities and trust preferred securities. The Company typically values these securities using third-party proprietary pricing models, primarily discounted cash flow valuation techniques, which incorporate both observable and unobservable inputs. Unobservable inputs that may impact the valuation of these securities include risk adjusted discount rates, projected prepayment rates, projected default rates and projected loss severity.

	Derivative financial instruments—Interest rate swaps are predominantly traded in over-the-counter markets and, as such, values are determined using widely accepted discounted cash flow modeling techniques. These discounted cash flow models use projections of future cash payments and receipts that are discounted at mid-market rates. Observable inputs that may impact the valuation of these instruments include LIBOR swap rates, LIBOR forward yield curves and counterparty credit risk spreads. These fair value measurements are generally classified within level 2 of the fair value hierarchy. Loan commitment derivatives are priced based on a bid pricing convention adjusted based on the Company’s historical fallout rates. Fallout rates are a significant unobservable input; therefore, these fair value measurements are classified within level 3 of the fair value hierarchy. The fair value of loan commitment derivatives is nominal.

The following table provides information about the valuation techniques and unobservable inputs used in the valuation of financial instruments falling within level 3 of the fair value hierarchy (dollars in thousands):

		Fair Value at			Valuation		Unobservable		Range (Weighted
		March 31, 2014			Technique		Input		Average)
Private label residential mortgage-backed securities and CMOs - Covered		$	172,070		Discounted cash flow		Voluntary prepayment rate		2.69% - 20.00% (6.78%)
							Probability of default		0.02% - 20.32% (3.80%)
							Loss severity		0.00% - 55.00% (19.05%)

Private label residential mortgage-backed securities and CMOs - Non-covered		$	14,849		Discounted cash flow		Voluntary prepayment rate		8.93% - 11.61% (10.77%)
							Probability of default		0.29% - 0.94% (0.74%)
							Loss severity		0.07% - 5.31% (3.90%)

The significant unobservable inputs impacting the fair value measurement of private label residential mortgage-backed securities include voluntary prepayment rates, probability of default and loss severity given default. Generally, significant increases in any of those inputs would result in a lower fair value measurement. Alternatively, decreases in any of those inputs would result in a higher fair value measurement. The fair value measurements of those securities with higher levels of subordination will be less sensitive to changes in these unobservable inputs, while securities with lower levels of subordination will show a higher degree of sensitivity to changes in these unobservable inputs. Generally, a change in the assumption used for probability of default is accompanied by a directionally similar change in the assumption used for loss severity given default and a directionally opposite change in the assumption used for voluntary prepayment rate.

Non-covered private label residential mortgage-backed securities for which fair value measurements are classified in level 3 of the fair value hierarchy at March 31, 2014 had an aggregate fair value of $15 million. These securities consisted of senior tranches issued from 2003 to 2004 collateralized by prime fixed rate and hybrid 1-4 single family residential mortgages originated from 2002 to 2004. These securities have coupons ranging from 2.5% to 2.6%, ratings ranging from Baa1 to A and subordination levels ranging from 8.4% to 11.3%.

The covered securities for which fair value measurements are categorized in level 3 of the fair value hierarchy at March 31, 2014 consisted of pooled trust preferred securities with a fair value of $5 million and private label residential mortgage-backed securities with a fair value of $172 million. The trust preferred securities are not material to the Company’s financial statements. The private label mortgage-backed securities were acquired in the FSB Acquisition and vary significantly with respect to seniority, subordination, collateral type and collateral performance; however, because of the Loss Sharing Agreements, the Company currently has minimal risk with respect to fluctuations in the value of these securities. These private label mortgage-backed securities had an amortized cost of $115 million and an aggregate fair value of $172 million at March 31, 2014. Gross unrealized losses related to securities in this group at March 31, 2014 were insignificant, totaling $77 thousand.

The Company uses third-party pricing services in determining fair value measurements for investment securities. To obtain an understanding of the methodologies and assumptions used, management reviews written documentation provided by the pricing services, conducts interviews with valuation desk personnel, performs on-site walkthroughs and reviews model results and detailed assumptions used to value selected securities as considered necessary. Management has established a robust price challenge process that includes a review by the treasury front office of all prices provided on a monthly basis. Any price evidencing unexpected month over month fluctuations or deviations from expectations is challenged. If considered necessary to resolve any discrepancies, a price will be obtained from an additional independent valuation source. The Company does not typically adjust the prices provided, other than through this established challenge process. The results of price challenges are subject to review by executive management. The Company has also established a quarterly process whereby prices provided by its primary pricing service for a sample of securities are validated. When there are price discrepancies, the final determination of fair value is based on careful consideration of the assumptions and inputs employed by each of the pricing sources.

Assets and liabilities measured at fair value on a non-recurring basis

Following is a description of the methodologies used to estimate the fair values of assets and liabilities measured at fair value on a non-recurring basis, and the level within the fair value hierarchy in which those measurements are typically classified.

Impaired loans and OREO - The carrying amount of collateral dependent impaired loans is typically based on the fair value of the underlying collateral, which may be real estate or other business assets, less estimated costs to sell. The carrying value of OREO is initially measured based on the fair value of the real estate acquired in foreclosure and subsequently adjusted to the lower of cost or estimated fair value, less estimated cost to sell. Fair values of real estate collateral are typically based on real estate appraisals which utilize market and income approaches to valuation incorporating both observable and unobservable inputs. When current appraisals are not available, the Company may use brokers’ price opinions, home price indices or other available information about changes in real estate market conditions to adjust the latest appraised value available. These adjustments to appraised values may be subjective and involve significant management judgment. The fair value of collateral consisting of other business assets is generally based on appraisals that use market approaches to valuation incorporating primarily unobservable inputs. Fair value measurements related to collateral dependent impaired loans and OREO are classified within level 3 of the fair value hierarchy.

The following tables present assets for which non-recurring changes in fair value have been recorded for the periods indicated (in thousands):

		Three Months Ended March 31, 2014

Derivative liabilities		3-Feb		45,028			45,028			43,791			43,791

The following methods and assumptions were used to estimate the fair value of each class of financial instruments, other than those described above:

The carrying amounts of certain financial instruments approximate fair value due to their short-term nature and generally negligible credit risk. These financial instruments include cash and cash equivalents, accrued interest receivable, short-term borrowings and accrued interest payable.

Non-marketable equity securities:

Non-marketable equity securities include FHLB and FRB stock. There is no market for these securities, which can be liquidated only by redemption by the issuer. These securities are carried at par, which has historically represented the redemption price and is therefore considered to approximate fair value. Non-marketable equity securities are evaluated quarterly for potential impairment.

Loans held for sale:

The fair value of conforming loans originated and held for sale is based on pricing currently available to the Company in the secondary market.

ACI and non-ACI loans:

Fair values are estimated based on a discounted cash flow analysis except as noted in the following paragraph. Estimates of future cash flows incorporate various factors that may include the type of loan and related collateral, estimated collateral values, estimated default probability and loss severity given default, internal risk rating, whether the interest rate is fixed or variable, term of loan, whether or not the loan is amortizing and loan specific net realizable value analyses for certain commercial and commercial real estate loans. The fair values of loans accounted for in pools are estimated on a pool basis. Other loans may be grouped based on risk characteristics and fair value estimated in the aggregate when applying discounted cash flow valuation techniques. Discount rates are based on current market rates for new originations of comparable loans adjusted for liquidity and credit risk premiums that the Company believes would be required by market participants.

At March 31, 2014, fair values of commercial ACI and non-ACI loans are estimated based on the pricing obtained in the sale of similar loans in March 31, 2014, adjusted for differences in LTV ratios.

New loans:

Fair values of residential loans are estimated using a discounted cash flow analysis with discount rates based on yields at which similar loans are trading in the secondary market, which reflect assumptions about credit risk. Fair values of commercial and consumer loans are estimated using a discounted cash flow analysis with discount rates based on interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The ALLL related to commercial and consumer loans is considered a reasonable estimate of the required adjustment to fair value to reflect the impact of credit risk. This estimate may not represent an exit value as defined in ASC 820.

FDIC indemnification asset:

The fair value of the FDIC indemnification asset has been estimated using a discounted cash flow technique incorporating assumptions about the timing and amount of future projected cash payments from the FDIC related to the resolution of covered assets. The factors that impact estimates of future cash flows are similar to those impacting estimated cash flows from ACI and non-ACI loans described above. The discount rate is determined by adjusting the risk free rate to incorporate uncertainty in the estimate of the timing and amount of future cash flows and illiquidity.

Deposits:

The fair value of demand deposits, savings accounts and money market deposits is the amount payable on demand at the reporting date. The fair value of time deposits is estimated using a discounted cash flow technique based on rates currently offered for deposits of similar remaining maturities.

Federal Home Loan Bank advances:

Fair value is estimated by discounting contractual future cash flows using the current rate at which borrowings with similar terms and remaining maturities could be obtained by the Company.

Commitments and Contingencies [Abstract]	'
Commitments and Contingencies	'
	Note 11 Commitments and Contingencies

	The Company issues off-balance sheet financial instruments to meet the financing needs of its customers. These financial instruments include commitments to fund loans, unfunded commitments under existing lines of credit, and commercial and standby letters of credit. These commitments expose the Company to varying degrees of credit and market risk which are essentially the same as those involved in extending loans to customers, and are subject to the same credit policies used in underwriting loans. Collateral may be obtained based on the Company’s credit evaluation of the counterparty. The Company’s maximum exposure to credit loss is represented by the contractual amount of these commitments. Amounts funded under non-cancellable commitments in effect at the date of the FSB Acquisition are covered under the Loss Sharing Agreements if certain conditions are met.

	Commitments to fund loans:

	These are agreements to lend funds to customers as long as there is no violation of any condition established in the contract. Commitments to fund loans generally have fixed expiration dates or other termination clauses and may require payment of a fee. Many of these commitments are expected to expire without being funded and, therefore, the total commitment amounts do not necessarily represent future liquidity requirements.

	Unfunded commitments under lines of credit:

	Unfunded commitments under lines of credit include commercial, commercial real estate, home equity and consumer lines of credit to existing customers. Some of these commitments may mature without being fully funded.

	Commercial and standby letters of credit:

	Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These letters of credit are primarily issued to support trade transactions or guarantee arrangements. Fees collected on standby letters of credit represent the fair value of those commitments and are deferred and amortized over their term, which is typically one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

	Total lending related commitments outstanding at March 31, 2014 were as follows (in thousands):

		Covered		Non-Covered		Total
	Commitments to fund loans	$	—	$	446,945	$	446,945
	Commitments to purchase loans	—		91,354		91,354

	Legal Proceedings

	The Company is involved as plaintiff or defendant in various legal actions arising in the normal course of business. In the opinion of management, based upon advice of legal counsel, the likelihood is remote that the impact of these proceedings, either individually or in the aggregate, would be material to the Company’s consolidated financial position, results of operations or cash flows.

	In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and disclosures of contingent assets and liabilities. Actual results could differ significantly from these estimates.



	Significant estimates include the allowance for loan and lease losses, the amount and timing of expected cash flows from covered assets and the FDIC indemnification asset, the fair values of investment securities and other financial instruments and the valuation of OREO. Management has used information provided by third party valuation specialists to assist in the determination of the fair values of investment securities and OREO.
