Rajinder Singh, Chairman, President and Chief Executive Officer, said, "This quarter was a pivotal one for BankUnited, positioning us well for the future. We executed the final loan sale under our loss sharing agreement with the FDIC, and would like to thank the FDIC for being a great partner over the past 9 years. We also sold our taxi medallion portfolio, terminated the Bank's operating agreement with the OCC and completed the full $300 million in share repurchases authorized by our Board in 2018. We also turned in another good quarter of DDA growth; non-interest bearing demand deposits grew by 18% for 2018."

Performance Highlights

• During the quarter ended December 31, 2018, pursuant to the terms of the Single Family Shared-Loss Agreement and consent received from the FDIC, the Bank executed a portfolio sale of certain covered loans and OREO. This sale was the final sale conducted under the terms of the Single Family Shared-Loss Agreement. Covered loans with an unpaid principal balance ("UPB") totaling approximately $260 million were sold; covered loans with a UPB totaling $401 million and a carrying value of $201 million at December 31, 2018 were retained in portfolio. See the section entitled "Covered Loans" below for further discussion.
• During the quarter ended December 31, 2018, the Bank sold substantially all of its taxi medallion finance loans. The provision for loan losses related to taxi medallion loans for the quarter ended December 31, 2018 totaled $14.0 million. This provision, net of tax, impacted diluted earnings per share by $0.10.
• For the quarter ended December 31, 2018, total deposits increased by a record $1.2 billion, of which $208 million was non-interest bearing demand deposits. Total deposits increased by $1.6 billion for the year ended December 31, 2018. During 2018, non-interest bearing demand deposits grew by 18% or $550 million. Non-covered loans and leases, including equipment under operating lease, grew by $257 million, net of a $79 million reduction in outstanding taxi medallion loans, during the quarter ended December 31, 2018. For the year ended December 31, 2018, non-covered loans and leases grew by $965 million.
• Net interest income increased by $56.2 million to $295.1 million for the quarter ended December 31, 2018 from $238.8 million for the quarter ended December 31, 2017. Interest income increased by $102.2 million, driven by increases in the average balances of loans and investment securities outstanding as well as increases in yields on interest earning assets, particularly on the covered loans. Interest expense increased by $45.9 million, driven primarily by increases in average interest bearing deposits and an increase in the cost of interest bearing liabilities. For the year ended December 31, 2018, net interest income increased by $99.8 million to $1.1 billion from $950.3 million for the year ended December 31, 2017.
• The net interest margin, calculated on a tax-equivalent basis, was 4.01% for the quarter ended December 31, 2018 compared to 3.51% for the immediately preceding quarter ended September 30, 2018 and 3.52% for the quarter ended December 31, 2017. Significant factors contributing to the increase in the net interest margin from the comparable quarter of the prior year were (i) an increase in accretion related to covered loans and (ii) increases in yields on other categories of interest earning assets; offset by (iii) an increase in the cost of interest bearing liabilities and (iv) the impact on tax equivalent yields of the reduction in the statutory federal income tax rate.
• During the quarter ended December 31, 2018, the Company repurchased approximately 4.7 million shares of its common stock for an aggregate purchase price of $150 million. During the year ended December 31, 2018, the Company repurchased approximately 8.4 million shares of its common stock for an aggregate purchase price of $300 million.
• On January 22, 2019 the Board of Directors of the Company authorized the repurchase of up to an additional $150 million in shares of its outstanding common stock, subject to any applicable regulatory approvals. Any repurchases will be made in accordance with applicable securities laws from time to time in open market or private transactions. The extent to which the Company repurchases shares, and the timing of such repurchases, will depend upon a variety of factors, including market conditions, the Company’s capital position, regulatory requirements and other considerations. No time limit was set for the completion of the share repurchase program, and the program may be suspended or discontinued at any time.
• Book value per common share grew to $29.49 at December 31, 2018 from $28.32 at December 31, 2017 while tangible book value per common share increased to $28.71 from $27.59 over the same period.
• As previously disclosed, on November 28, 2018, the operating agreement between the Bank and the Office of the Comptroller of the Currency ("OCC") was terminated.

(1)Net income and diluted earnings per common share, each excluding the impact of a discrete income tax benefit and related professional fees and Non-loss share diluted earnings per share are non-GAAP financial measures. See section entitled "Non-GAAP Financial Measures" below for reconciliation of non-GAAP financial measurements to their comparable GAAP financial measurements.

Capital

The Company and its banking subsidiary continue to exceed all regulatory guidelines required to be considered well capitalized. The Company’s and BankUnited, N.A.'s regulatory capital ratios at December 31, 2018 were as follows:

		BankUnited, Inc.				BankUnited, N.A.
Tier 1 leverage		9.0%				9.6%
Common Equity Tier 1 ("CET1") risk-based capital		12.6%				13.5%
Tier 1 risk-based capital		12.6%				13.5%
Total risk-based capital		13.1%				14.0%

Covered loans

During the quarter ended December 31, 2018, the Bank executed a portfolio sale of certain covered loans and OREO. Covered loans with UPB totaling approximately $260 million and covered OREO totaling $5.2 million were sold during the quarter ended December 31, 2018. In conjunction with the sale, the FDIC indemnification asset was amortized to zero as of December 31, 2018 as expectations of losses eligible for indemnification with respect to any retained loans prior to final termination of the Single Family Shared-Loss Agreement are insignificant.

The table below summarizes the impact on pre-tax earnings of the covered asset sale, accretion on covered loans and amortization of the indemnification asset for the quarter ended December 31, 2018 (in thousands):

		Three Months Ended December 31, 2018
Accretion on covered loans		$	121,349
Amortization of the FDIC indemnification asset		(128,911		)
Gain on sale of covered loans and OREO		169
Net loss on FDIC indemnification related to sale of covered loans and OREO		(1,644		)
Net impact on pre-tax earnings		$	(9,037	)

The amount of accretion on covered loans and amortization of the FDIC indemnification asset recognized in the financial statements differed from estimates previously disclosed primarily because the price received in the loan sale was higher than initially estimated.

Covered loans with UPB totaling $401 million and a carrying value of $201 million as of December 31, 2018 were retained in portfolio. Based on our updated estimates of expected cash flows, we expect total accretion on the retained covered loans over their expected remaining lives to approximate $287 million. The primary reason this amount differs from estimates previously disclosed is changes in prepayment assumptions. The yield on the retained loans as of December 31, 2018 was 32.9%.

Non-Loss Share Earnings

The table below presents the trend of Non-Loss Share earnings over the last three years:

			Year Ended				Quarter Ended
			12/31/2016				3/31/2017				6/30/2017				9/30/2017				(4) 12/31/2017				3/31/2018				6/30/2018				9/30/2018				12/31/2018

(1) Non-loss share EPS and EPS, Loss Share Contribution are non-GAAP measures. See section entitled "Non-GAAP Financial Measures" below for reconciliation of non-GAAP financial measurements to their comparable GAAP financial measurements.

(2) Loss Share Contribution is defined as the excess of Loss Share Earnings (generally defined as accretion on covered loans net of amortization of the FDIC indemnification asset) over the hypothetical amount of interest income that could have been earned if the average balance of covered loans and the indemnification asset were instead assumed to be invested in securities at the weighted average yield earned on the Company’s investment securities portfolio as reported for each respective quarter, net of related income taxes. See section entitled "Supplemental Calculations - Calculation of Loss Share Contribution and Non-Loss Share Earnings Per Share and Calculation of Hypothetical Interest Income on Alternate Assets" below for details of the calculation.

(3) See section entitled "Supplemental Calculations - Calculation of Loss Share Contribution and Non-Loss Share Earnings Per Share" below for details of the calculation.

(4) EPS for the quarter ended December 31, 2017 is shown net of discrete income tax benefit and related professional fees. EPS, net of discrete income tax benefit and related professional fees is a non-GAAP financial measure. See section entitled "Non-GAAP Financial Measures" below for reconciliation of this measure to the GAAP measure of earnings per common share, diluted.

Loans and Leases

Loans, including premiums, discounts and deferred fees and costs, totaled $22.0 billion at December 31, 2018 compared to $21.4 billion at December 31, 2017. Non-covered loans grew to $21.8 billion while covered loans declined to $201 million at December 31, 2018.

A comparison of non-covered loan and lease portfolio composition at the dates indicated follows (dollars in thousands):

		December 31, 2018							September 30, 2018							December 31, 2017
Residential and other consumer loans		$	4,747,604			21.8	%		$	4,563,578			21.0	%		$	4,196,080			19.8	%

Equipment under operating lease, net		$	702,354						$	661,677						$	599,502

Residential and other consumer loans grew by $184 million for the quarter ended December 31, 2018. Multi-family loans declined by $178 million for the quarter ended December 31, 2018, primarily due to continued run-off of the New York portfolio, which decreased by $146 million. Commercial and industrial loans, inclusive of owner occupied commercial real estate, grew by $110 million for the quarter ended December 31, 2018, driven largely by growth in both the Florida and New York portfolios, partially offset by mortgage warehouse lending, which decreased by $105 million and the sale of taxi medallion loans.

Asset Quality and Allowance for Loan and Lease Losses

For the quarters ended December 31, 2018 and 2017, the Company recorded provisions for loan losses of $12.6 million and $5.2 million, respectively, substantially all of which related to non-covered loans. For the years ended December 31, 2018 and 2017, the Company recorded provisions for loan losses of $25.9 million and $68.7 million, respectively, substantially all of which related to non-covered loans. The Company recorded provisions of $14.0 million and $8.6 million related to taxi medallion loans for the quarters ended December 31, 2018 and December 31, 2017, respectively. For the years ended December 31, 2018 and 2017, the provision related to taxi medallion loans totaled $26.2 million and $58.2 million, respectively.

The most significant factor impacting the increase in the provision for loan losses related to non-covered loans for the quarter ended December 31, 2018 as compared to the quarter ended December 31, 2017 was the increase in the provision related to taxi medallion loans resulting from the sale of substantially the entire portfolio. Additional contributing factors included (i) a $5 million release during the quarter ended December 31, 2017 of reserves related to the impact of hurricanes partially offset by (ii) lower loan growth and (iii) a net decrease in the provision related to certain quantitative and qualitative loss factors.

Significant factors impacting the decrease in the provision for loan losses related to non-covered loans for the year ended December 31, 2018 as compared to the year ended December 31, 2017 were (i) a decrease in the provision related to taxi medallion loans; (ii) lower loan growth; (iii) a net decrease in the provision related to certain quantitative and qualitative loss factors; partially offset by (iv) an increase in the provision related to specific reserves for loans other than taxi medallion loans.

Non-performing loans totaled $129.9 million or 0.59% of total loans at December 31, 2018, compared to $173.4 million or 0.81% of total loans at December 31, 2017. The ratios of the allowance for loan and lease losses to total loans and to non-performing loans were 0.50% and 84.63%, respectively, at December 31, 2018, compared to 0.68% and 83.53%, at December 31, 2017. The ratio of net charge-offs to average loans was 0.28% for the year ended December 31, 2018, compared to 0.38% for the year ended December 31, 2017. The ratio of net charge-offs of taxi medallion loans to average loans was 0.18% for the year ended December 31, 2018, compared to 0.28% for the year ended December 31, 2017. The most significant factor impacting the decline in the ratio of non-performing loans to total loans at December 31, 2018 compared to December 31, 2017 was the sale of the taxi medallion loan portfolio during the quarter ended December 31, 2018. The most significant factors impacting the decline in the ratio of the allowance for loan and lease losses to total loans were (i) the elimination of the reserve related to taxi medallion loans in conjunction with the sale of those loans; (ii) a decrease in certain loss factors; and (iii) a decline in total criticized, classified and impaired loans, which typically carry higher reserves on a percentage basis, as a percentage of total loans.

The following table summarizes the activity in the allowance for loan and lease losses for the periods indicated (in thousands):

		Three Months Ended December 31, 2018												Three Months Ended December 31, 2017
		Covered Loans				Non- Covered Loans				Total				Covered Loans				Non- Covered Loans				Total
Balance at beginning of period		$	14			$	124,726			$	124,740			$	4,848			$	153,725			$	158,573

Balance at end of period		$	30			$	109,901			$	109,931			$	258			$	144,537			$	144,795

Charge-offs related to taxi medallion loans totaled $25.0 million and $9.5 million for the quarters ended December 31, 2018 and 2017, respectively, and $38.4 million and $56.6 million for the years ended December 31, 2018 and 2017.

Deposits

At December 31, 2018, deposits totaled $23.5 billion compared to $21.9 billion at December 31, 2017. The average cost of total deposits was 1.52% for the quarter ended December 31, 2018, compared to 1.35% for the immediately preceding quarter ended September 30, 2018, and 0.94% for the quarter ended December 31, 2017. The average cost of total deposits was 1.28% for the year ended December 31, 2018, compared to 0.83% for the year ended December 31, 2017.

Net interest income

Net interest income for the quarter ended December 31, 2018 increased to $295.1 million from $238.8 million for the quarter ended December 31, 2017. Net interest income was $1.1 billion for the year ended December 31, 2018, compared to $950.3 million for the year ended December 31, 2017. Increases in interest income were partially offset by increases in interest expense. The increases in interest income were primarily attributable to increases in the average balances of loans and investment securities and related average yields, particularly on the covered loans. Interest expense increased due to increases in average interest bearing deposits and the cost of funds.

The Company’s net interest margin, calculated on a tax-equivalent basis, was 4.01% for the quarter ended December 31, 2018, compared to 3.51% for the immediately preceding quarter ended September 30, 2018 and 3.52% for the quarter ended December 31, 2017. Net interest margin, calculated on a tax-equivalent basis, was 3.67% for the year ended December 31, 2018, compared to 3.65% for the year ended December 31, 2017.

The most significant factor impacting the increases in net interest margin for the quarter and year ended December 31, 2018 compared to the quarter and year ended December 31, 2017 was the increase in the yield on covered loans to 147.37% and 86.13%, respectively, for the quarter and year ended December 31, 2018 from 60.90% and 55.22% for the quarter and year ended December 31, 2017. This increase reflected accelerated accretion related to the final covered loan sale that occurred during the quarter ended December 31, 2018. This acceleration resulted from changes in both the expected timing of cash flows from the final loan sale and in the estimated selling price of loans included in the sale compared to assumptions previously modeled.

Other offsetting contributing factors included:

• The tax-equivalent yield on non-covered loans increased to 4.18% and 4.00%, respectively, for the quarter and the year ended December 31, 2018, compared to 3.80% and 3.75% for the quarter and year ended December 31, 2017. The most significant factor contributing to the increased yield on non-covered loans was the impact of increases in benchmark interest rates.
• The tax-equivalent yield on investment securities increased to 3.59% and 3.35%, respectively, for the quarter and year ended December 31, 2018 from 2.89% and 3.02% for the quarter and year ended December 31, 2017.
• Tax-equivalent yields on non-covered loans and investment securities and the net interest margin were each negatively impacted by approximately 0.09% for the quarter ended December 31, 2018 as compared to the quarter ended December 31, 2017 as a result of the reduction in the statutory federal income tax rate. For the year ended December 31, 2018 as compared to the year ended December 31, 2017, the tax rate change negatively impacted the net interest margin by approximately 0.08%.
• Growth of non-covered loans and investment securities at yields lower than the overall yield on interest earning assets, which is impacted by the yield on covered loans.
• The average rate on interest bearing liabilities increased to 1.95% and 1.66%, respectively for the quarter and year ended December 31, 2018, from 1.25% and 1.12% for the quarter and year ended December 31, 2017, reflecting higher average rates on both interest bearing deposits and FHLB advances. Increases in the cost of interest bearing liabilities primarily reflect increases in market interest rates and extension of the duration of FHLB advances.

Non-interest income

Non-interest income totaled $33.3 million and $132.0 million, respectively, for the quarter and year ended December 31, 2018 compared to $46.5 million and $157.9 million, respectively, for the quarter and year ended December 31, 2017.

Significant factors contributing to the decreases in non-interest income for the quarter and year ended December 31, 2018 compared to the quarter and year ended December 31, 2017 included (i) decreases of $4.1 million and $30.3 million, respectively, in gain on investment securities; (ii) decreases of $17.5 million and $6.8 million, respectively, in gain on sale of covered loans, inclusive of the impact of FDIC indemnification; partially offset by (iii) increases of $2.2 million and $7.8 million, respectively, in lease financing income and (iv) increases of $5.4 million and $7.7 million, respectively, in fair value adjustments of residential mortgage servicing rights. All of the Company's residential mortgage servicing rights were sold in the quarter ended December 31, 2018.

Gain on investment securities for the year ended December 31, 2017 included gains from the sale of certain securities formerly covered under the Commercial Shared-Loss Agreement and originally acquired at significant discounts in the FSB Acquisition.

Non-interest expense

Non-interest expense totaled $246.7 million and $740.5 million, respectively, for the quarter and year ended December 31, 2018 compared to $161.3 million and $635.0 million for the quarter and year ended December 31, 2017. The most significant component of the increases in non-interest expense was the increase in amortization of the FDIC indemnification asset. Amortization of the FDIC indemnification asset was $128.9 million and $261.8 million, respectively, for the quarter and year ended December 31, 2018, compared to $41.1 million and $176.5 million for the quarter and year ended December 31, 2017. The increased amortization related in large part to the execution of the final covered loan sale pursuant to the Single Family Shared-Loss Agreement, as discussed above.

Provision for income taxes

The effective income tax rate was 24.2% and 21.8% for the quarter and year ended December 31, 2018, compared to (251.3)% and (51.9)% for the quarter and year ended December 31, 2017. The effective income tax rates for the quarter and year ended December 31, 2017 reflect a discrete income tax benefit of $327.9 million recognized during the fourth quarter 2017. Excluding the impact of the discrete income tax benefit and the impact of the change in the federal statutory income tax rate on deferred tax assets and liabilities existing on the date of enactment of the Tax Cuts and Jobs Act of 2017 ("TCJA"), the effective income tax rate⁽²⁾ was 27.6% and 30.1%, respectively, for the quarter and year ended December 31, 2017.

These declines in the effective income tax rate were primarily attributable to the reduction of the statutory corporate federal income tax rate from 35% to 21%, effective January 1, 2018. The effective income tax rate differed from the statutory federal income tax rate of 21% for the quarter and year ended December 31, 2018 and of 35% for the quarter and year ended December 31, 2017 due primarily to income not subject to tax, offset by state income taxes.

(2)Effective income tax rate, excluding the impact of the discrete income tax benefit and the impact of the change in the federal statutory income tax rate on deferred income tax assets and liabilities existing at the date of enactment of the TCJA is a non-GAAP measure. See section entitled "Non-GAAP Financial Measures" below for reconciliation of non-GAAP financial measurements to their comparable GAAP financial measurements.

Concurrently with the FSB Acquisition, BankUnited entered into two loss sharing agreements, or the Loss Sharing Agreements, which covered certain legacy assets, including the entire legacy loan portfolio and OREO, and certain purchased investment securities. Assets covered by the Loss Sharing Agreements are referred to as “covered assets” (or, in certain cases, “covered loans”). The Loss Sharing Agreements do not apply to subsequently purchased or originated loans or other assets. Effective May 22, 2014 and consistent with the terms of the Loss Sharing Agreements, loss share coverage was terminated for those commercial loans and OREO and certain investment securities that were previously covered under the Loss Sharing Agreements. 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, including certain interest and expenses, up to the $4.0 billion stated threshold and 95% of losses in excess of the $4.0 billion stated threshold. The amount of cumulative losses incurred on the covered assets, as of December 31, 2018, is approximately $3.4 billion. Cumulative reimbursements received or receivable from the FDIC under the Loss Sharing Agreements for claims filed for incurred losses as of December 31, 2018 totaled $2.7 billion.

Supplemental Calculations

Calculation of Loss Share Contribution and Non-Loss Share Earnings Per Share

Non-Loss Share Earnings are calculated by removing the total Loss Share Contribution from Net Income. The Loss Share Contribution is a hypothetical presentation of the impact of the covered loans and FDIC indemnification asset on earnings for each respective quarter, reflecting the excess of Loss Share Earnings over hypothetical interest income that could have been earned on alternative assets (in millions except share and per share data):

(1) See section entitled "Supplemental Calculations - Calculation of Hypothetical Interest Income on Alternate Assets" below for calculation of these amounts and underlying assumptions.

(2) Net income and diluted earnings per common share for the three months ended December 31, 2017 are presented net of non-GAAP adjustments to remove a discrete income tax benefit and related professional fees recognized in that period. See section entitled "Non-GAAP Financial Measures" below.

(3) Calculation variances of $0.1 million in the table above are due to rounding.

(4) An assumed marginal tax rate of 39.5% was applied to the quarter ended December 31, 2017 and all prior periods; a marginal rate of 26.5% was applied to subsequent periods reflecting the reduction of the statutory federal income tax rate.

Calculation of Hypothetical Interest Income on Alternate Assets

The hypothetical interest income calculated below reflects the estimated income that may have been earned if the average balance of covered loans and the FDIC indemnification asset were liquidated and the proceeds assumed to be invested in securities at the weighted average yield on the Company’s investment securities portfolio as reported for each respective quarter. Historically, cash received from the repayment, sale, or other resolution of covered loans and cash payments received from the FDIC under the terms of the Shared Loss Agreement have generally been reinvested in non-covered loans or investment securities. There is no assurance that the hypothetical results illustrated below would have been achieved if the covered loans and FDIC indemnification asset had been liquidated and proceeds reinvested in the respective quarters (dollars in millions):

		Year Ended				Quarter Ended
		12/31/2016				3/31/2017				6/30/2017				9/30/2017				12/31/2017				3/31/2018				6/30/2018				9/30/2018				12/31/2018

Non-GAAP Financial Measures

Net income and diluted earnings per common share, in each case excluding the impact of Loss Share Contribution, as defined in the section entitled "Non-Loss Share Earnings" above, are non-GAAP financial measures. Management believes disclosure of these measures provides readers with information that may be useful in understanding the impact of the covered loans and FDIC indemnification asset on the Company’s earnings. The following table reconciles these non-GAAP financial measurements to the comparable GAAP financial measurements of net income and diluted earnings per common share for the periods indicated (in millions except share and per share data. Shares in thousands):

The effective tax rate excluding the impact of the discrete income tax benefit and the impact of the change in the federal statutory rate on existing deferred tax assets and liabilities is a non-GAAP financial measure. Management believes disclosure of this measure enhances readers' ability to compare the Company's financial performance for the current period to that of other periods presented. The following table reconciles this non-GAAP financial measurement to the comparable GAAP financial measurement of the effective tax rate for the three months and year ended December 31, 2017 (dollars in thousands):

		Three Months Ended December 31, 2017				Year Ended December 31, 2017
Effective income tax rate, excluding the impact of a discrete income tax benefit and impact of enactment of the Tax Cuts and Jobs Act of 2017:
Effective income tax rate (GAAP)		(251.3		)%		(51.9		)%
Less impact on effective income tax rate of discrete income tax benefit and enactment of the Tax Cuts and Jobs Act of 2017 (non-GAAP)		278.9		%		82.0		%
