NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Principles of Consolidation

The consolidated financial statements include the accounts of CMS Bancorp, Inc. (the “Company”) and its wholly-owned subsidiary, CMS Bank (the “Bank”). The Company’s business is conducted principally through the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified in the consolidated financial statements to conform to the current presentation.

2. Description of Business, Nature of Operations and Pending Merger

The Bank was originally chartered in 1887 as Community Savings and Loan, a New York State-chartered savings and loan association. In 1980, it converted to a New York State-chartered savings bank and changed its name to Community Mutual Savings Bank of Southern New York. In 1983, Community Mutual Savings Bank of Southern New York changed its name to Community Mutual Savings Bank. In 2007, the Bank reorganized to a federally-chartered mutual savings bank and simultaneously converted from a federally-chartered mutual savings bank to a federally-chartered stock savings bank, with the concurrent formation of the Company. The Company, a stock holding company for the Bank, conducted a public offering of its common stock in connection with the conversion. After the 2007 conversion and offering, all of the Bank’s stock became owned by the Company. In June 2012, the Bank completed its conversion from a federally-chartered savings bank to a New York state-chartered savings bank after receiving approval from the New York State Department of Financial Services (“NYSDFS”) and non-objection from the Office of the Comptroller of the Currency (“OCC”), and changed its name to CMS Bank. The Company will continue to be regulated as a savings and loan holding company by the Federal Reserve Bank of Philadelphia as long as the Bank continues to meet the requirements to remain a “qualified thrift lender” under the Home Owners’ Loan Act.

The Bank is a community and customer-oriented retail savings bank offering residential mortgage loans and traditional deposit products and commercial real estate, small business and consumer loans in Westchester County, New York, and the surrounding areas. The Bank also invests in various types of assets, including securities of various government-sponsored enterprises, corporations, municipalities and mortgage-backed securities. The Bank’s revenues are derived principally from interest on loans, interest and dividends received from its investment securities and fees for bank services. The Bank’s primary sources of funds are deposits, scheduled amortization and prepayments of loan principal and mortgage-backed securities, maturities and calls of investment securities, funds provided by operations and borrowings from the Federal Home Loan Bank of New York (“FHLB”).

On August 10, 2012, the Company announced that it entered into a definitive merger agreement (“Merger Agreement”) with Customers Bancorp, Inc., headquartered in Wyomissing, Pennsylvania (“Customers”) whereby through a series of transactions, the Company will be merged into Customers, and the Bank will be merged into Customers’ wholly-owned bank subsidiary, Customers Bank, a Pennsylvania state-chartered bank headquartered in Phoenixville, Pennsylvania (the “Merger”). Upon completion of the Merger, Customers will have acquired all outstanding shares of CMS Bancorp’s common stock in exchange for shares of Customers’ common stock. Any fractional shares that result due to this exchange of shares will be paid in cash. The total transaction value, as calculated on the date of the merger announcement, was approximately $20.8 million

Effective as of April 22, 2013, the Company and Customers entered into an Amendment to Agreement and Plan of Merger (“Amendment”) to the Merger Agreement. The Amendment extended from April 30, 2013 to December 31, 2013 the initial date at which, if the merger of the Company with and into Customers has not closed, either the Company or Customers may terminate the Merger Agreement, subject to the termination date being extended until March 31, 2014 under certain specified circumstances. The Amendment also updated the definitions of “CMS Valuation” and “Customers Valuation,” establishing the valuation date for book value as of March 31, 2013. The exchange ratio will remain fixed for the pendency of the transaction, using the multiples of 0.95x for the Company’s common equity, and 1.25x for Customers common equity for purposes of calculating the exchange ratio.

Other key terms agreed to by the Company and Customers under the Amendment include: (a) a right for the Company to terminate the Merger Agreement, as amended, exercisable at any time after May 20, 2013, if either (i) Customers has not made the contemplated investment in the Company of $1.5 million of Company Preferred Stock, or (ii) Customers and the Company have not agreed upon the terms of the $2.0 million senior secured lending facility that Customers shall make available to the Company; and (b) an agreement by Customers to pay the Company a termination fee of $1.0 million in the event the Merger Agreement, as amended, is terminated under certain provisions primarily relating to failure to consummate the Parent Merger due to non-receipt of required government approvals. Also pursuant to the Amendment, Customers reimbursed the Company for $300,000 of merger-related expenses.

The Merger Agreement, as amended, has been unanimously approved by CMS Bancorp’s Board of Directors and the transactions contemplated by the Merger Agreement are subject to various conditions including, among other things, (i) approval of the Merger by the holders of a majority of the outstanding shares of CMS Bancorp’s common stock; (ii) the receipt of all required regulatory approvals; (iii) the non-occurrence of any event that has a material adverse effect on CMS Bancorp and its subsidiaries; and (iv) as of the closing date (before giving effect to the Merger), CMS Bancorp and its subsidiaries shall have, on a consolidated basis, nonperforming assets (as defined in the Merger Agreement) less than or equal to $12 million, as well as other conditions to closing that are customary in

transactions such as the Merger. The Amendment removed the previous condition to Customers’ obligation to commence the filing of regulatory applications ( i.e. , the closing of the Acacia Federal Savings Bank transaction). Assuming the satisfaction of such conditions, it is currently expected that the Merger will be completed in late 2013 or early 2014. For additional information about the Merger announcement, see the Company’s Forms 8-K filed with the U.S. Securities and Exchange Commission (“SEC”) on August 10, 2012 and April 24, 2013.

3. Basis of Presentation

The accompanying unaudited consolidated financial statements were prepared in accordance with instructions for Form 10-Q and Regulation S-X and do not include information or footnotes necessary for a complete presentation of financial condition, results of operations, and cash flows in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). However, in the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the financial statements have been included. The results of operations for the three and six months ended March 31, 2013 are not necessarily indicative of the results which may be expected for the entire fiscal year. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto which are in the Company’s Annual Report for the fiscal year ended September 30, 2012, filed with the SEC on December 28, 2012.

The Company follows Financial Accounting Standards Board (“FASB”) guidance on subsequent events, which establishes general standards for accounting for and disclosure of events that occur after the balance sheet date but before the financial statements are issued. This guidance sets forth the period after the balance sheet date during which management of the reporting entity should evaluate events or transactions that occur for potential recognition in the financial statements. This guidance identifies the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements, and the disclosure that should be made about events or transactions that occur after the balance sheet date. In preparing these consolidated financial statements, the Company evaluated the events that occurred after March 31, 2013 and through the date these consolidated financial statements were issued.

4. Critical Accounting Policies

The consolidated financial statements included in this report have been prepared in conformity with U.S. GAAP. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the statements of financial condition and revenues and expenses for the periods then ended. Actual results could differ significantly from those estimates.

It is management’s opinion that accounting estimates covering certain aspects of the business have more significance than others due to the relative importance of those areas to overall performance, or the level of subjectivity required in making these estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses and the assessment of whether deferred tax assets are more likely than not to be realized.

Management believes that the allowance for loan losses represents its best estimate of losses known and inherent in the loan portfolio that are both probable and reasonable to estimate. While management uses available information to recognize losses on loans, future additions to the allowance for loan losses may be necessary based on changes in market and economic conditions in the Company’s market area. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses. Such agencies may require the Company to recognize additions to the allowance for loan losses based on their judgments about information available to them at the time of their examination. Management’s assessment as to the amount of deferred tax assets that are more likely than not to be realized is based upon future taxable income, which is subject to revision upon availability of updated information.

5. Net Income (Loss) Per Share

Basic net income (loss) per share was computed by dividing the net income (loss) by the weighted average number of shares of common stock outstanding, adjusted for unearned shares of the Company’s employee stock ownership plan, or “ESOP”. Stock options granted are considered common stock equivalents and are therefore considered in diluted net income per share calculations, if dilutive, using the treasury stock method. All outstanding stock options were anti-dilutive and therefore excluded from the computation of diluted net income (loss) per share for the three month and six month periods ended March 31, 2013 and 2012.

6. Retirement Plan – Components of Net Periodic Pension Cost

The components of periodic pension expense were as follows:

7. Stock Based Compensation

At a special meeting of the stockholders of the Company held on November 9, 2007, the stockholders approved the CMS Bancorp, Inc. 2007 Stock Option Plan and the CMS Bancorp, Inc. 2007 Recognition and Retention Plan (collectively the “Plans”). The Plans authorize the award of up to 205,516 stock options and 82,206 shares of restricted stock. The stock options and restricted stock awarded under the Plans vest over a five year service period based on the anniversary of the grant date.

The Company recorded compensation expense with respect to stock options of $7,000 and $25,000 during the three month periods ended March 31, 2013 and 2012, respectively, and $27,000 and $50,000 during the six month periods ended March 31, 2013 and 2012, respectively. Unrecognized compensation expense associated with stock option grants as of March 31, 2013 was $149,000.

The Company recorded compensation expense with respect to restricted stock of $12,000 and $37,000 during the three month periods ended March 31, 2013 and 2012, respectively, and $43,000 and $73,000 during the six month periods ended March 31, 2013 and 2012, respectively. Unrecognized compensation expense associated with grants of restricted stock as of March 31, 2013 was $109,000.

8. Securities

Securities available for sale as of March 31, 2013 and September 30, 2012 were as follows:

Table of Contents

There were no securities with unrealized losses at September 30, 2012. The unrealized losses reported on securities at March 31, 2013 relate to three securities issued by U.S. Government Agencies and one mortgaged-backed security.

The age of unrealized losses and fair value of related securities available for sale at March 31, 2013 were as follows:

When the fair value of security is below its amortized cost, and depending on the length of time the condition exists, additional analysis is performed to determine whether an other-than-temporary impairment condition exists. Securities are analyzed quarterly for possible other-than-temporary impairment. The analysis considers (i) whether the Company has the intent to sell the securities prior to recovery and/or maturity and (ii) whether it is more likely than not that the Company will have to sell the securities prior to recovery and/or maturity. Often, the information available to conduct these assessments is limited and rapidly changing, making estimates of fair value subject to judgment. If actual information or conditions are different than estimated, the extent of the impairment of the security may be different than previously estimated, which could have a material effect on the Company’s consolidated financial statements.

All mortgage-backed securities are U.S. Government Agencies backed and collateralized by residential mortgages.

There were no sales of securities available for sale during the six month period ended March 31, 2013. During the six months ended March 31, 2012, the Company sold available for sale securities with a carrying value of $20.6 million, and recognized a gain of $539,000 on such sales.

9. Loans

Loans receivable are carried at unpaid principal balances and net deferred loan origination costs less the allowance for loan losses.

The Company defers loan origination fees and certain direct loan origination costs and accretes net amounts as an adjustment of yield over the contractual lives of the related loans. Unamortized net fees and costs are written off if the loan is repaid before its stated maturity date.

Recognition of interest income is discontinued and existing accrued interest receivable is reversed on loans that are more than ninety days delinquent and where management, through its loan review process, feels such loan should be classified as non-accrual. Income is subsequently recognized only to the extent that cash payments are received until the obligation has been brought current, has performed in accordance with the contractual terms for a reasonable period of time (generally six months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt, in which case the loan is returned to an accrual status. The past due status of all classes of loans receivable is determined based on the contractual due dates for loan payments.

Loan balances as of March 31, 2013 and September 30, 2012 consist of the following:

Table of Contents

An allowance for loan and lease losses (“ALLL”) is maintained to absorb losses from the loan portfolio. The ALLL is based on management’s continuing evaluation of the risk characteristics and credit quality of the loan portfolio, assessment of current economic conditions, diversification and size of the portfolio, adequacy of collateral, past and anticipated loss experience, and the amount of non-performing loans.

The Bank’s methodology for determining the ALLL is based on the requirements of the FASB’s Accounting Standards Codification (“ASC”) Sub-Topic 450-20 for loans collectively evaluated for impairment, ASC Section 310-10-35 for loans individually evaluated for impairment, as well as the Interagency Policy Statement on the Allowance for Loan and Lease Losses, and other bank regulatory guidance.

Loans that are collectively evaluated for impairment are analyzed with general allowances being made as appropriate. For general allowances, historical loss trends and Federal Deposit Insurance Corporation Uniform Bank Performance Report (“UBPR”) loss experience for the Bank’s Peer Group are used in the estimation of losses in the current portfolio. These historical loss amounts are modified by other qualitative factors.

The classes described below, which are based on the Federal Thrift Financial Report classifications, provide the starting point for the ALLL analysis. Management tracks the historical net charge-off activity at the reporting class level. A historical charge-off factor is calculated utilizing one year to five year averages, depending on the trend of losses and other factors. In addition, the UBPR Peer Group charge-off factor is determined. The Bank uses Bank specific charge-off experience adjusted for recent loss trends and economic conditions as well as Peer Group charge-off experience to establish its historical charge-off factor.

“Pass” rated credits are segregated from “Classified” credits for the application of qualitative factors. Management has identified a number of additional qualitative factors that it uses to supplement the historical charge-off factor because these factors are likely to cause estimated credit losses associated with the existing loan pools to differ from historical loss experience. The additional factors that are evaluated quarterly and updated using information obtained from internal, regulatory, and governmental sources are: national and local economic trends and conditions; levels of and trends in delinquency rates and non-accrual loans; trends in volumes and terms of loans; effects of changes in lending policies; experience, ability, and depth of lending staff; value of underlying collateral; and concentrations of credit from a loan type, industry and/or geographic standpoint.

An allowance for loan losses is maintained at a level that represents management’s best estimate of losses known and inherent in the loan portfolio that are both probable and reasonably estimable. The allowance is decreased by loan charge-offs, increased by subsequent recoveries of loans previously charged off, and then adjusted, via either a charge or credit to operations, to an amount determined by management to be necessary. Loans or portions thereof are charged off when, after collection efforts are exhausted, they are determined to be uncollectible. Management of the Company, in determining the allowance for loan losses, considers the losses inherent in its loan portfolio and changes in the nature and volume inherent in its loan activities, along with the general economic and real estate market conditions. The total of the two components represents the Bank’s ALLL. The Company utilizes a two tier approach: (1) identification of impaired loans and establishment of specific loss allowances on such loans; and (2) establishment of general valuation allowances on the remainder of its loan portfolio. The Company maintains a loan review system which allows for a periodic review of its loan portfolio and the early identification of potential impaired loans.

Such system takes into consideration, among other things, delinquency status, size of loans, and type of collateral and financial condition of the borrowers. Specific loan loss allowances are established for identified loans based on a review of such information and/or appraisals of the underlying collateral. General loan losses are determined based upon a combination of factors including, but not limited to, actual loan loss experience, composition of the loan portfolio, current economic conditions and management’s judgment. Although management believes that specific and general loan losses are established in accordance with management’s best estimate, actual losses are dependent upon future events and, as such, further additions to the level of loan loss allowances may be necessary.

The segments of the Bank’s loan portfolio are disaggregated to a level that allows management to monitor risk and performance. Loans secured by real estate consist of one-to-four-family, multi-family, non-residential, construction and home equity and second mortgage loans. Substantially all of the commercial loans are secured and consumer loans are principally secured.

Management uses a six category internal risk rating system to monitor the credit quality of the overall loan portfolio that generally follows bank regulatory definitions. Pass graded loans are considered to have average or better than average risk characteristics. They demonstrate satisfactory debt service capacity and coverage along with a generally stable financial position. These loans are performing in accordance with the terms of their loan agreement. The Watch category, a non bank regulatory category, includes assets that, while performing, demonstrate above average risk through a pattern of declining earnings trends, strained cash flow, increasing leverage, and/or weakening market fundamentals. The Special Mention category includes assets that are currently protected but exhibit potential credit weakness or a downward trend which, if not checked or corrected, will weaken the Bank’s asset or inadequately protect the Bank’s position. Loans in the Substandard category have a well-defined weakness that jeopardizes the orderly liquidation of the debt. For loans in this category, normal repayment from the borrower is in jeopardy and there is a distinct possibility that a partial loss of interest and/or principal will occur if the deficiencies are not corrected. All loans greater than 90 days past due are considered Substandard. Loans in the Doubtful category have weaknesses inherent in those classified Substandard with the added provision that the weakness makes collection of debt in

full, on the basis of current existing facts, conditions, and values, highly questionable and improbable. The portion of any loan that represents a specific allocation of the allowance for loan losses is placed in the special valuation category. Loans that are deemed incapable of repayment where continuance as an active asset of the Bank is not warranted are charged off as a Loss. The classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off the asset even though partial recovery may be achieved in the future.

To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Bank has a structured loan rating process with several layers of internal and external oversight. Generally, consumer and residential mortgage loans are included in the Pass categories unless a specific action, such as delinquency, bankruptcy, repossession, or death occurs to raise awareness of a possible credit event. The Bank’s Senior Lending Officer is responsible for the timely and accurate risk rating of the loans in the portfolios at origination and on an ongoing basis. The Bank has an experienced outsourced Loan Review function that on a quarterly basis, reviews and assesses loans within the portfolio and the adequacy of the Bank’s allowance for loan losses. Detailed reviews, including plans for resolution, are performed on loans classified as Substandard or Doubtful on a quarterly basis. Loans in the Special Mention and Substandard categories that are collectively evaluated for impairment are given separate consideration in the determination of the allowance.

Management evaluates individual loans in all of the segments for possible impairment if the loan is either in nonaccrual status, or is risk rated Substandard or Doubtful. Loans are considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in evaluating impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of any shortfall in relation to the principal and interest owed.

Once the determination has been made that a loan is impaired, the determination of whether a specific allocation of the allowance is necessary is measured by comparing the recorded investment in the loan to the fair value of the loan using one of three methods: (a) the present value of expected future cash flows discounted at the loan’s effective interest rate; (b) the loan’s observable market price; or (c) the fair value of the collateral less selling costs. The method is selected on a loan-by-loan basis, with management primarily utilizing the fair value of collateral method. The evaluation of the need and amount of a specific allocation of the allowance and whether a loan can be removed from impairment status is made on a quarterly basis. The Bank’s policy for recognizing interest income on impaired loans does not differ from its overall policy for interest recognition. A loan evaluated for impairment is deemed to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. All loans identified as impaired are evaluated independently. The Company does not aggregate such loans for evaluation purposes. A reserve for losses related to unfunded lending commitments is also maintained. This reserve represents management’s estimate of losses inherent in unfunded credit commitments.

The following table summarizes the primary segments of the loan portfolio, including net deferred loan origination fees and costs, as of March 31, 2013 and September 30, 2012:

Subsequent to March 31, 2013, $2.7 million of the impaired loans was collected.
