LOANS RECEIVABLE AND ALLOWANCE FOR LOAN LOSSES | NOTE 9 — LOANS RECEIVABLE AND ALLOWANCE FOR LOAN LOSSES The Company’s loan portfolio includes originated and purchased loans. Originated and purchased loans, for which there was no evidence of credit deterioration at their acquisition date, are referred to collectively as non-PCI loans. Purchased credit impaired (“PCI ”) loans are accounted for in accordance with ASC Subtopic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality . A purchased loan is deemed to be credit impaired when there is evidence of credit deterioration since its origination and it is probable at the acquisition date that the Company would be unable to collect all contractually required payments. PCI loans consist of loans acquired with deteriorated quality from the United Commercial Bank (“UCB”) FDIC assisted acquisition on November 6, 2009, the Washington First International Bank (“WFIB”) FDIC assisted acquisition on June 11, 2010 and, to a lesser extent, a small portion of loans acquired from the MetroCorp acquisition on January 17, 2014 . Refer to Note 3 — Business Combination , included in this report, for further details on the MetroCorp acquisition and Note 8 — Covered Assets and FDIC Indemnification Asset to the Consolidated Financial Statements of the Company’s 2014 Form 10-K for additional details related to the WFIB and UCB acquisitions.

The Company’s CRE lending activities include loans to finance income-producing properties, construction and land loans. The Company’s C&I lending activities include commercial business financing for small and middle-market businesses in a wide spectrum of industries. Included in commercial business loans are loans for working capital, accounts receivable lines, inventory lines, Small Business Administration loans and lease financing. The Company also offers a variety of international trade finance services and products, including letters of credit, revolving lines of credit, import loans, bankers’ acceptances, working capital lines, domestic purchase financing and pre-export financing. The Company’s single-family residential loans are primarily comprised of adjustable rate (“ARM”) first mortgage loans secured by one-to-four unit residential properties. The Company’s ARM single-family residential loan programs generally have a one-year or three-year initial fixed period. The Company’s multifamily residential loans are primarily comprised of variable rate loans that have a six-month or three-year initial fixed period. As of June 30, 2015 and December 31, 2014 , consumer loans were primarily composed of home equity lines of credit (“HELOCs”). All loans originated are subject to the Company’s underwriting guidelines and loan origination standards. Management believes that the Company’s underwriting criteria and procedures adequately consider the unique risks which may come from these products. The Company conducts a variety of quality control procedures and periodic audits, including review of criteria for lending and legal requirements, to ensure it is in compliance with its origination standards. As of June 30, 2015 and December 31, 2014 , loans totaling $15.40 billion and $14.66 billion , respectively, were pledged to secure borrowings and to provide additional borrowing capacity from the FHLB and the Federal Reserve Bank. Credit Quality Indicators All loans are subject to the Company’s internal and external credit review and monitoring. Loans are risk rated based on analysis of the current state of the borrower’s credit quality. The analysis of credit quality includes a review of all repayment sources, the borrower’s current payment performance/delinquency, current financial and liquidity status and all other relevant information. For single-family residential loans, payment performance/delinquency is the driving indicator for the risk ratings. However, the risk ratings remain the overall credit quality indicator for the Company as well as the credit quality indicator utilized for estimating the appropriate allowance for loan losses. The Company utilizes a seven-grade risk rating system, which can be classified within the following categories: Pass, Watch, Special Mention, Substandard, Doubtful and Loss. The risk ratings reflect the relative strength of the repayment sources. Pass and Watch loans are generally considered to have sufficient sources of repayment in order to repay the loan in full in accordance with all terms and conditions. These borrowers may have some credit risks that require monitoring, but full repayments are expected. Special Mention loans are considered to have potential weaknesses that warrant closer attention by management. Special Mention is considered a transitory grade. If any potential weaknesses are resolved, the loan is upgraded to a Pass or Watch grade. If negative trends in the borrower’s financial status or other information indicates that the repayment sources may become inadequate, the loan is downgraded to a Substandard grade. Substandard loans are considered to have well-defined weaknesses that jeopardize the full and timely repayment of the loan. Substandard loans have a distinct possibility of loss if the deficiencies are not corrected. Additionally, when management has assessed a potential for loss but a distinct possibility of loss is not recognizable, the loan is still classified as Substandard. Doubtful loans have insufficient sources of repayment and a high probability of loss. Loss loans are considered to be uncollectible and of such little value that they are no longer considered bankable assets. These internal risk ratings are reviewed routinely and adjusted due to changes in the borrowers’ status and likelihood of loan repayment.

Additionally, non-PCI loans that are not 90 or more days past due but have identified deficiencies are also placed on nonaccrual status. Interest payments received on nonaccrual loans are reflected as a reduction of principal and not as interest income. A loan is returned to accrual status when the borrower has demonstrated a satisfactory payment trend subject to management’s assessment of the borrower’s ability to repay the loan. PCI loans are excluded from the above aging analysis table as such loans continue to earn interest from accretable yield, independent of performance in accordance with their contractual terms. $59.1 million and $63.4 million of PCI loans were on nonaccrual status as of June 30, 2015 and December 31, 2014 , respectively. Loans in Process of Foreclosure As of June 30, 2015 and December 31, 2014, the Company had $22.2 million and $16.9 million , respectively, of recorded investment in consumer mortgage loans secured by residential real estate properties, for which formal foreclosure proceedings were in process according to local requirements of the applicable jurisdiction, which were not included in OREO. Foreclosed residential real estate properties with carrying amount of $4.1 million were included in total net OREO of $25.8 million as of June 30, 2015 . In comparison, foreclosed residential real estate properties with carrying amount of $3.5 million were included in total net OREO of $32.1 million as of December 31, 2014 . Troubled Debt Restructurings A troubled debt restructuring (“TDR”) is a modification of the terms of a loan when the lender, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower. The concessions may be granted in various forms, including a below-market change in the stated interest rate, reduction in the loan balance or accrued interest, extension of the maturity date with a stated interest rate lower than the current market rate or note splits referred to as A/B notes. In A/B note restructurings, the original note is bifurcated into two notes where the A note represents the portion of the original loan which allows for acceptable loan-to-value and debt coverage on the collateral and is expected to be collected in full and the B note represents the portion of the original loan where there is a shortfall in value and is fully charged off. The A/B note balance is comprised of the A note balance only. A notes are not disclosed as TDRs in subsequent years after the year of restructuring if the restructuring agreement specifies an interest rate equal to or greater than the rate that the Company was willing to accept at the time of the restructuring for a new loan with comparable risk, the loan is not impaired based on the terms specified by the restructuring agreement and has demonstrated a period of sustained performance under the modified terms. The Company had $2.8 million and $2.9 million of performing A/B notes as of June 30, 2015 and December 31, 2014 , respectively. Potential TDRs are individually evaluated and the type of restructuring is selected based on the loan type and the circumstances of the borrower’s financial difficulty in order to maximize the Company’s recovery. During the three months ended June 30, 2015 , the Company restructured $38.1 million of C&I loans primarily through principal and interest reductions and extensions and $100 thousand of CRE loans through other modified terms . During the three months ended June 30, 2014 , the Company restructured $5.3 million of CRE loans primarily through principal and interest reductions , $4.0 million of residential loans through principal deferments and other modified terms and $1.2 million of C&I loans primarily through extensions . During the six months ended June 30, 2015 , the Company restructured $918 thousand of CRE loans through principal and interest deferments and other modified terms , $38.3 million of C&I loans primarily through principal and interest reductions and extensions and $281 thousand of residential loans through principal deferments . During the six months ended June 30, 2014 , the Company restructured $8.1 million residential loans through extensions, rate reductions, principal deferments and other modified terms , $5.3 million of CRE loans primarily through principal and interest reductions and $2.8 million of C&I loans primarily through extensions and principal deferments . The following tables present the additions to non-PCI TDRs during the three and six months ended June 30, 2015 and 2014 : Loans Modified as TDRs During the Three Months Ended June 30, 2015 2014 ($ in thousands) Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (1) Financial Impact (2) Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (1) Financial Impact (2) CRE: Income producing — $ — $ — $ — 2 $ 5,318 $ 5,254 $ — Land 1 $ 171 $ 100 $ 102 — $ — $ — $ — C&I: Commercial business 12 $ 37,924 $ 38,117 $ 5,465 2 $ 1,165 $ 1,155 $ 563 Residential: Single-family — $ — $ — $ — 1 $ 1,032 $ 1,030 $ — Multifamily — $ — $ — $ — 1 $ 2,513 $ 2,973 $ — Loans Modified as TDRs During the Six Months Ended June 30, 2015 2014 ($ in thousands) Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (1) Financial Impact (2) Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (1) Financial Impact (2) CRE: Income producing 1 $ 828 $ 818 $ — 2 $ 5,318 $ 5,254 $ — Land 1 $ 171 $ 100 $ 102 — $ — $ — $ — C&I: Commercial business 13 $ 38,090 $ 38,280 $ 5,497 7 $ 2,886 $ 2,828 $ 1,811 Residential: Single-family 1 $ 281 $ 281 $ 2 4 $ 6,855 $ 5,105 $ — Multifamily — $ — $ — $ — 1 $ 2,513 $ 2,973 $ — (1) Includes subsequent payments after modification and reflects the balance as of June 30, 2015 and 2014 . (2) The financial impact includes charge-offs and specific reserves recorded at modification date. Subsequent to restructuring, a TDR that becomes delinquent, generally beyond 90 days, is considered to have defaulted. There were no subsequent defaults during the three and six months ended June 30, 2015 for non-PCI loans that were modified as TDRs within the previous 12 months. Non-PCI loans that were modified as TDRs within the previous 12 months that have subsequently defaulted during the three months ended June 30, 2014 consisted of one C&I TDR contract with a recorded investment of $500 thousand . Non-PCI loans that were modified as TDRs within the previous 12 months that have subsequently defaulted during the six months ended June 30, 2014 consisted of one CRE TDR contract with a recorded investment of $2.7 million and one C&I with a recorded investment of $500 thousand . TDRs may be designated as performing or nonperforming. A TDR may be designated as performing if the loan has demonstrated sustained performance under the modified terms. The period of sustained performance may include the periods prior to modification if prior performance has met or exceeded the modified terms. A loan will remain on nonaccrual status until the borrower demonstrates a sustained period of performance, generally six consecutive months of payments. TDRs are included in the impaired loan quarterly valuation allowance process. See Allowance for Loan Losses and Impaired Loans sections below for complete discussion. All portfolio segments of TDRs are reviewed for necessary specific reserves in the same manner as impaired loans of the same portfolio segment which have not been identified as TDRs. The modification of the terms of each TDR is considered in the current impairment analysis of the respective TDR. For all portfolio segments of nonperforming TDRs, when the restructured loan is deemed to be uncollectible under modified terms and its fair value is less than the recorded investment in the loan, the deficiency is charged off against the allowance for loan losses. If the loan is a performing TDR, the deficiency is included in the specific reserves of the allowance for loan losses, as appropriate. The amount of additional funds committed to lend to borrowers whose terms have been modified w ere immaterial as of June 30, 2015 and December 31, 2014 . Impaired Loans The Company’s loans are grouped into heterogeneous and homogeneous (mostly consumer loans) categories. Classified loans in the heterogeneous category are identified and evaluated for impairment on an individual basis. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all scheduled payments of principal or interest due according to the original contractual terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as expedient, at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent, less costs to sell. When the value of an impaired loan is less than the recorded investment in the loan and the loan is classified as nonperforming and uncollectible, the deficiency is charged-off against the allowance for loan losses. Impaired loans exclude the homogeneous consumer loan portfolio which is evaluated collectively for impairment. The Company’s impaired loans predominantly include non-PCI loans held - for - investment on nonaccrual status and any non-PCI loans modified in a TDR, on both accrual and nonaccrual status. The following tables present the non-PCI impaired loans as of June 30, 2015 and December 31, 2014 : ($ in thousands) Unpaid Principal Balance Recorded Investment With No Allowance Recorded Investment With Allowance Total Recorded Investment Related Allowance June 30, 2015 CRE: Income producing $ 53,002 $ 34,274 $ 11,295 $ 45,569 $ 1,447 Construction 57 — 14 14 3 Land 10,755 4,455 1,354 5,809 191 C&I: Commercial business 83,775 18,687 52,778 71,465 22,584 Trade finance 11,452 — 11,452 11,452 106 Residential: Single-family 16,926 5,930 9,606 15,536 493 Multifamily 25,899 17,299 6,241 23,540 250 Consumer 1,253 643 610 1,253 2 Total $ 203,119 $ 81,288 $ 93,350 $ 174,638 $ 25,076 ($ in thousands) Unpaid Principal Balance Recorded Investment With No Allowance Recorded Investment With Allowance Total Recorded Investment Related Allowance December 31, 2014 CRE: Income producing $ 58,900 $ 35,495 $ 15,646 $ 51,141 $ 1,581 Construction 6,913 6,913 — 6,913 — Land 13,291 2,838 5,622 8,460 1,906 C&I: Commercial business 44,569 12,723 25,717 38,440 15,174 Trade finance 12,967 6,431 274 6,705 28 Residential: Single-family 18,908 6,003 11,398 17,401 461 Multifamily 37,649 21,523 12,890 34,413 313 Consumer 1,259 1,151 108 1,259 1 Total $ 194,456 $ 93,077 $ 71,655 $ 164,732 $ 19,464 The following table presents the average recorded investment and the amount of interest income recognized on non-PCI impaired loans for the three and six months ended June 30, 2015 and 2014 : Three Months Ended Six Months Ended 2015 2014 2015 2014 ($ in thousands) Average Recorded Investment Recognized Interest Income (1) Average Recognized Interest Income (1) Average Recorded Investment Recognized Interest Income (1) Average Recognized Interest Income (1) CRE: Income producing $ 46,042 $ 134 $ 59,121 $ 281 $ 46,897 $ 268 $ 59,917 $ 627 Construction 14 — 6,888 — 14 — 6,888 — Land 5,876 10 12,128 75 5,951 20 12,179 149 C&I: Commercial business 73,306 761 41,592 209 71,644 1,550 42,682 420 Trade finance 11,623 51 546 4 11,739 134 559 8 Residential: Single-family 15,595 68 15,131 57 15,658 137 14,034 115 Multifamily 23,690 190 36,683 180 23,757 379 36,817 360 Consumer 1,256 12 755 7 1,258 23 752 14 Total impaired non-PCI loans $ 177,402 $ 1,226 $ 172,844 $ 813 $ 176,918 $ 2,511 $ 173,828 $ 1,693 (1) Includes interest recognized on accruing non-PCI TDRs. Interest payments received on nonaccrual non-PCI loans are generally reflected as a reduction of principal and not as interest income. Allowance for Loan Losses The allowance for loan losses on non-PCI loans consists of specific reserves and general reserves. The Company’s non-PCI loans fall into heterogeneous and homogeneous categories. Impaired loans are subject to specific reserves. Loans in the homogeneous category, as well as non-impaired loans in the heterogeneous category, are evaluated as part of the general reserves. General reserves are calculated by utilizing both quantitative and qualitative factors. There are different qualitative risks for the loans in each portfolio segment. The residential and CRE segments’ predominant risk characteristics are the collateral and the geographic location of the property collateralizing the loan. The risk is qualitatively assessed based on the total real estate loan concentration in those geographic areas. The C&I segment’s predominant risk characteristics are the global cash flows of the borrowers and guarantors and economic and market conditions. Consumer loans are largely comprised of HELOCs for which the predominant risk characteristic is the real estate collateral securing the loans. The Company also maintains an allowance for loan losses on PCI loans when there is deterioration in credit quality subsequent to acquisition. Based on the Company’s estimates of cash flows expected to be collected, the Company establishes an allowance for the PCI loans, with a charge to income through the provision for loan losses. As of June 30, 2015 , the Company has established an allowance of $612 thousand on $1.17 billion of PCI loans. As of December 31, 2014 , an allowance of $714 thousand was established on $1.32 billion of PCI loans. The allowance balances for both periods were allocated mainly to the PCI CRE loan pools. The Company’s methodology to determine the overall appropriateness of the allowance is based on a classification migration model and qualitative considerations. The migration model examines pools of loans having similar characteristics and analyzes their loss rates over a historical period. The Company assigns loss rates to each loan grade within each pool of loans. Loss rates derived by the migration model are based predominantly on historical loss trends that may not be entirely indicative of the actual or inherent loss potential. As such, the Company utilizes qualitative and environmental factors as adjusting mechanisms to supplement the historical results of the classification migration model. Qualitative considerations include, but are not limited to, prevailing economic or market conditions, relative risk profiles of various loan segments, volume concentrations, growth trends, delinquency and nonaccrual status, problem loan trends and geographic concentrations. Qualitative and environmental factors are reflected as percentage adjustments and are added to the historical loss rates derived from the classified asset migration model to determine the appropriate allowance for each loan pool. When determined uncollectible, it is the Company’s policy to promptly charge-off the difference in the outstanding loan balance and the fair value of the collateral or the discounted value of expected cash flows. Recoveries are recorded when payment is received on loans that were previously charged-off through the allowance for loan losses. Allocation of a portion of the allowance to one segment of the loan portfolio does not preclude its availability to absorb losses in other segments.
