Total gross unrealized losses were primarily attributable to rising interest rates relative to when the investment securities were purchased and not due to the credit quality of the investment securities. The contractual cash flows of the investment securities are backed by the full faith and credit guaranty of the United States government or an agency of the government. ASB does not intend to sell the securities before the recovery of its amortized cost basis and there have been no adverse changes in the timing of the contractual cash flows for the securities. ASB did not recognize OTTI for the quarters ended June 30, 2016 and 2015. U.S. Treasury and federal agency obligations have contractual terms to maturity. Mortgage-related securities have contractual terms to maturity, but require periodic payments to reduce principal. In addition, expected maturities will differ from contractual maturities because borrowers have the right to prepay the underlying mortgages. The contractual maturities of available-for-sale investment securities were as follows: June 30, 2016 Amortized cost Fair value (in thousands) Due in one year or less $ 9,991 $ 10,001 Due after one year through five years 81,303 83,162 Due after five years through ten years 81,439 83,406 Due after ten years 21,315 21,590 194,048 198,159 Mortgage-related securities-FNMA,FHLMC and GNMA 686,506 695,862 Total available-for-sale securities $ 880,554 $ 894,021 Allowance for loan losses.

ASB performs an internal loan review and grading on an ongoing basis. The review provides management with periodic information as to the quality of the loan portfolio and effectiveness of its lending policies and procedures. The objectives of the loan review and grading procedures are to identify, in a timely manner, existing or emerging credit trends so that appropriate steps can be initiated to manage risk and avoid or minimize future losses. Loans subject to grading include commercial, commercial real estate and commercial construction loans. Each loan is assigned an Asset Quality Rating (AQR) reflecting the likelihood of repayment or orderly liquidation of that loan transaction pursuant to regulatory credit classifications: Pass, Special Mention, Substandard, Doubtful and Loss. The AQR is a function of the PD Model rating, the loss given default and possible non-model factors which impact the ultimate collectability of the loan such as character of the business owner/guarantor, interim period performance, litigation, tax liens and major changes in business and economic conditions. Pass exposures generally are well protected by the current net worth and paying capacity of the obligor or by the value of the asset or underlying collateral. Special Mention loans have potential weaknesses that, if left uncorrected, could jeopardize the liquidation of the debt. Substandard loans have well-defined weaknesses that jeopardize the liquidation of the debt and are characterized by the distinct possibility that the Bank may sustain some loss. An asset classified Doubtful has the weaknesses of those classified Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The credit risk profile by internally assigned grade for loans was as follows: June 30, 2016 December 31, 2015 (in thousands) Commercial real estate Commercial construction Commercial Commercial real

Troubled debt restructurings. A loan modification is deemed to be a troubled debt restructuring (TDR) when ASB grants a concession it would not otherwise consider were it not for the borrower’s financial difficulty. When a borrower experiencing financial difficulty fails to make a required payment on a loan or is in imminent default, ASB takes a number of steps to improve the collectability of the loan and maximize the likelihood of full repayment. At times, ASB may modify or restructure a loan to help a distressed borrower improve its financial position to eventually be able to fully repay the loan, provided the borrower has demonstrated both the willingness and the ability to fulfill the modified terms. TDR loans are considered an alternative to foreclosure or liquidation with the goal of minimizing losses to ASB and maximizing recovery. ASB may consider various types of concessions in granting a TDR including maturity date extensions, extended amortization of principal, temporary deferral of principal payments and temporary interest rate reductions. ASB rarely grants principal forgiveness in its TDR modifications. Residential loan modifications generally involve interest rate reduction, extending the amortization period, or capitalizing certain delinquent amounts owed not to exceed the original loan balance. Land loans at origination are typically structured as a three -year term, interest-only monthly payment with a balloon payment due at maturity. Land loan TDR modifications typically involve extending the maturity date up to five years and converting the payments from interest-only to principal and interest monthly, at the same or higher interest rate. Commercial loan modifications generally involve extensions of maturity dates, extending the amortization period and temporary deferral or reduction of principal payments. ASB generally does not reduce the interest rate on commercial loan TDR modifications. Occasionally, additional collateral and/or guaranties are obtained. All TDR loans are classified as impaired and are segregated and reviewed separately when assessing the adequacy of the allowance for loan losses based on the appropriate method of measuring impairment: (1) present value of expected future cash flows discounted at the loan’s effective original contractual rate, (2) fair value of collateral less cost to sell or (3) observable market price. The financial impact of the calculated impairment amount is an increase to the allowance associated with the modified loan. When available information confirms that specific loans or portions thereof are uncollectible (confirmed losses), these amounts are charged off against the allowance for loan losses. Loan modifications that occurred and the impact on the allowance for loan losses were as follows: Three months ended June 30, 2016 Six months ended June 30, 2016 Number of contracts Outstanding recorded investment 1 Net increase in allowance Number of contracts Outstanding recorded investment 1 Net increase in allowance (dollars in thousands) Pre-modification Post-modification (as of period end) Pre-modification Post-modification (as of period end) Troubled debt restructurings Real estate: Residential 1-4 family 5 $ 891 $ 885 $ 98 9 $ 1,988 $ 2,100 $ 259 Commercial real estate — — — — — — — — Home equity line of credit 8 768 768 181 18 1,437 1,437 255 Residential land 1 120 121 — 1 120 121 — Commercial construction — — — — — — — — Residential construction — — — — — — — — Commercial 5 457 457 145 8 16,657 16,657 670 Consumer — — — — — — — — 19 $ 2,236 $ 2,231 $ 424 36 $ 20,202 $ 20,315 $ 1,184 Three months ended June 30, 2015 Six months ended June 30, 2015 Number of contracts Outstanding recorded 1 Net increase in allowance Number of contracts Outstanding recorded 1 Net increase in allowance (dollars in thousands) Pre-modification Post-modification (as of period end) Pre-modification Post-modification (as of period end) Troubled debt restructurings Real estate: Residential 1-4 family 2 $ 318 $ 318 $ — 7 $ 1,195 $ 1,213 $ 47 Commercial real estate — — — — — — — — Home equity line of credit 13 690 690 105 22 1,119 1,119 160 Residential land — — — — — — — — Commercial construction — — — — — — — — Residential construction — — — — — — — — Commercial 3 161 161 78 4 253 253 78 Consumer — — — — — — — — 18 $ 1,169 $ 1,169 $ 183 33 $ 2,567 $ 2,585 $ 285 1 The reported balances include loans that became TDR during the period, and were fully paid-off, charged-off, or sold prior to period end. Loans modified in TDRs that experienced a payment default of 90 days or more in the indicated periods, and for which the payment of default occurred within one year of the modification, were as follows: Three months ended June 30, 2016 Six months ended June 30, 2016 (dollars in thousands) Number of contracts Recorded investment Number of contracts Recorded investment Troubled debt restructurings that subsequently defaulted Real estate: Residential 1-4 family — $ — 1 $ 488 Commercial real estate — — — — Home equity line of credit — — — — Residential land — — — — Commercial construction — — — — Residential construction — — — — Commercial 1 26 1 26 Consumer — — — — 1 $ 26 2 $ 514 There were no loans modified in TDRs that experienced a payment default of 90 days or more in the second quarter of 2015 and six months ended June 30, 2015, and for which the payment of default occurred within one year of the modification. If loans modified in a TDR subsequently default, ASB evaluates the loan for further impairment. Based on its evaluation, adjustments may be made in the allocation of the allowance or partial charge-offs may be taken to further write-down the carrying value of the loan. Commitments to lend additional funds to borrowers whose loan terms have been modified in a TDR totaled $2.7 million at June 30, 2016 . Mortgage servicing rights . In its mortgage banking business, ASB sells residential mortgage loans to government-sponsored entities and other parties, who may issue securities backed by pools of such loans. ASB retains no beneficial interests in these loans other than the servicing rights of certain loans sold. ASB received proceeds from the sale of residential mortgages of $58.1 million and $95.0 million for the three months ended June 30, 2016 and 2015 and $98.5 million and $173.3 million for the six months ended June 30, 2016 and 2015, respectively, and recognized gains on such sales of $1.5 million and $2.1 million for the three months ended June 30, 2016 and 2015 and $2.7 million and $3.9 million for the six months ended June 30, 2016 and 2015 respectively. There were no repurchased mortgage loans for the three months ended June 30, 2016 and 2015 and six months ended June 30, 2016 and 2015. The repurchase reserve was $0.1 million and nil for the period ended June 30, 2016 and 2015, respectively. Mortgage servicing fees, a component of other income, net, were $0.7 million and $0.9 million for the three months ended June 30, 2016 and 2015 and $1.4 million and $1.8 million for the six months ended June 30, 2016 and 2015, respectively. Changes in the carrying value of mortgage servicing rights were as follows: (in thousands) Gross 1 Accumulated amortization 1 Valuation allowance Net June 30, 2016 $ 15,652 $ (6,636 ) $ — $ 9,016 December 31, 2015 14,531 (5,647 ) — 8,884 1 Reflects the impact of loans paid in full. Changes related to mortgage servicing rights were as follows: (in thousands) 2016 2015 Mortgage servicing rights Balance, January 1 $ 8,884 $ 11,749 Amount capitalized 1,120 2,001 Amortization (988 ) (1,444 ) Other-than-temporary impairment — (4 ) Carrying amount before valuation allowance, June 30 9,016 12,302 Valuation allowance for mortgage servicing rights Balance, January 1 — 209 Provision (recovery) — (168 ) Other-than-temporary impairment — (4 ) Balance, June 30 — 37 Net carrying value of mortgage servicing rights $ 9,016 $ 12,265 ASB capitalizes mortgage servicing rights acquired through either the purchase or origination of mortgage loans for sale with servicing rights retained. On a monthly basis, ASB compares the net carrying value of the mortgage servicing rights to its fair value to determine if there are any changes to the valuation allowance and/or other-than-temporary impairment for the mortgage servicing rights. ASB’s MSRs are stratified based on predominant risk characteristics of the underlying loans including loan type such as fixed-rate 15 and 30 year mortgages and note rate in bands of 50 to 100 basis points. For each stratum, fair value is calculated by discounting expected net income streams using discount rates that reflect industry pricing for similar assets. Changes in mortgage interest rates impact the value of ASB’s mortgage servicing rights. Rising interest rates typically result in slower prepayment speeds in the loans being serviced for others, which increases the value of mortgage servicing rights, whereas declining interest rates typically result in faster prepayment speeds which decrease the value of mortgage servicing rights and increase the amortization of the mortgage servicing rights. Expected net income streams are estimated based on industry assumptions regarding prepayment expectations and income and expenses associated with servicing residential mortgage loans for others. ASB uses a present value cash flow model using techniques described above to estimate the fair value of MSRs. Impairment is recognized through a valuation allowance for each stratum when the carrying amount exceeds fair value, with any associated provision recorded as a component of loan servicing fees included in other income, net in the consolidated statements of income. A direct write-down is recorded when the recoverability of the valuation allowance is deemed to be unrecoverable. Key assumptions used in estimating the fair value of ASB’s mortgage servicing rights used in the impairment analysis were as follows: (dollars in thousands) June 30, 2016 December 31, 2015 Unpaid principal balance $ 1,137,226 $ 1,097,314 Weighted average note rate 4.03 % 4.05 % Weighted average discount rate 9.4 % 9.6 % Weighted average prepayment speed 11.4 % 9.3 % The sensitivity analysis of fair value of MSR to hypothetical adverse changes of 25 and 50 basis points in certain key assumptions was as follows: (dollars in thousands) June 30, 2016 December 31, 2015 Prepayment rate: 25 basis points adverse rate change $ (567 ) $ (561 ) 50 basis points adverse rate change (1,037 ) (1,104 ) Discount rate: 25 basis points adverse rate change (97 ) (111 ) 50 basis points adverse rate change (192 ) (220 ) The effect of a variation in certain assumptions on fair value is calculated without changing any other assumptions. This analysis typically cannot be extrapolated because the relationship of a change in one key assumption to the changes in the fair value of MSRs typically is not linear. Other borrowings. Securities sold under agreements to repurchase are accounted for as financing transactions and the obligations to repurchase these securities are recorded as liabilities in the balance sheet. ASB pledges investment securities as collateral for securities sold under agreements to repurchase. All such agreements are subject to master netting arrangements, which provide for conditional right of set-off in case of default by either party; however, ASB presents securities sold under agreements to repurchase on a gross basis in the balance sheet. The following tables present information about the securities sold under agreements to repurchase, including the related collateral received from or pledged to counterparties: (in millions) Gross amount of recognized liabilities Gross amount offset in the Balance Sheet Net amount of liabilities presented in the Balance Sheet Repurchase agreements June 30, 2016 $173 $— $173 December 31, 2015 229 — 229 Gross amount not offset in the Balance Sheet (in millions) Liabilities presented in the Balance Sheet Financial instruments Cash collateral pledged June 30, 2016 Financial institution $ 50 $ 57 $ — Government entities 27 42 — Commercial account holders 96 117 — Total $ 173 $ 216 $ — December 31, 2015 Financial institution $ 50 $ 56 $ — Government entities 56 61 — Commercial account holders 123 144 — Total $ 229 $ 261 $ — The securities underlying the agreements to repurchase are book-entry securities and were delivered by appropriate entry into the counterparties’ accounts or into segregated tri-party custodial accounts at the FHLB. Securities sold under agreements to repurchase are accounted for as financing transactions and the obligations to repurchase these securities are recorded as liabilities in the consolidated balance sheets. The securities underlying the agreements to repurchase continue to be reflected in ASB’s asset accounts. Derivative financial instruments. ASB enters into interest rate lock commitments (IRLCs) with borrowers, and forward commitments to sell loans or to-be-announced mortgage-backed securities to investors to hedge against the inherent interest rate and pricing risk associated with selling loans. ASB enters into IRLCs for residential mortgage loans, which commit ASB to lend funds to a potential borrower at a specific interest rate and within a specified period of |
