Loans comprise the majority of the assets acquired in these transactions, most of which are subject to loss sharing agreements with the FDIC whereby the FDIC has agreed to reimburse the Company for 80% of losses incurred on the purchased loans, other real estate owned ("OREO"), and certain other assets. Additionally, the loss share agreements with the FDIC require the Company to reimburse the FDIC in the event that actual losses on covered assets are lower than the original loss estimates agreed upon with the FDIC with respect of such assets in the loss share agreements. The Company refers to the loans subject to these loss-sharing agreements as "covered loans" and uses the term "covered assets" to refer to covered loans, covered OREO and certain other covered assets. On February 10, 2012, the Company announced that its wholly-owned subsidiary bank, Barrington Bank, acquired certain assets and liabilities and the banking operations of Charter National Bank and Trust ("Charter National") in an FDIC-assisted transaction. At the acquisition date, the Company estimated the fair value of the reimbursable losses to be approximately $13.2 million. In 2011, the Company estimated the fair value of the reimbursable losses to be approximately $273.3 million for the First Chicago Bank & Trust ("First Chicago") acquisition, $48.9 million for The Bank of Commerce ("TBOC") acquisition and $6.7 million for the Community First Bank-Chicago ("CFBC") acquisition, at their respective acquisition dates. For the three acquisitions subject to loss share agreements in 2010, the Company estimated the fair value of the reimbursable losses to be approximately $44.0 million for the Ravenswood Bank ("Ravenswood") acquisition, and $113.8 million for the Lincoln Park Savings Bank ("Lincoln Park") and Wheatland Bank ("Wheatland") acquisitions. The agreements with the FDIC require that the Company follow certain servicing procedures or risk losing the FDIC reimbursement of covered asset losses.

The loans covered by the loss sharing agreements are classified and presented as covered loans and the estimated reimbursable losses are recorded as an FDIC indemnification asset in the Consolidated Statements of Condition. The Company recorded the acquired assets and liabilities at their estimated fair values at the acquisition date. The fair value for loans reflected expected credit losses at the acquisition date. Therefore, the Company will only recognize a provision for credit losses and charge-offs on the acquired loans for any further credit deterioration. See Note 7 — Allowance for Loan Losses, Allowance for Losses on Lending-Related Commitments and Impaired Loans for further discussion of the allowance on covered loans. The Charter National acquisition resulted in bargain purchase gain of approximately $840,000. The 2011 transactions resulted in bargain purchase gains of a total of $38.0 million, including $27.4 million for First Chicago, $8.6 million for TBOC and $2.0 million for CFBC, and are shown as a component of non-

interest income on the Company's Consolidated Statements of Income. In 2010, FDIC-assisted transactions resulted in bargain purchase gains of a total of $33.3 million, including $6.8 million for Ravenswood, $22.3 million for Wheatland, and $4.2 million for Lincoln Park.

As stated above, in conjunction with FDIC-assisted transactions, the Company entered into loss share agreements with the FDIC. These agreements cover realized losses on loans, foreclosed real estate and certain other assets. These loss share assets are measured separately from the loan portfolios because they are not contractually embedded in the loans and are not transferable with the loans should the Company choose to dispose of them. Fair values at the acquisition dates were estimated based on projected cash flows available for loss-share based on the credit adjustments estimated for each loan pool and the loss share percentages. The loss share assets are also separately measured from the related loans and foreclosed real estate and recorded as FDIC indemnification assets on the Consolidated Statements of Condition. Subsequent to the acquisition date, reimbursements received from the FDIC for actual incurred losses will reduce the FDIC indemnification assets. Reductions to expected losses, to the extent such reductions to expected losses are the result of an improvement to the actual or expected cash flows from the covered assets, will also reduce the FDIC indemnification assets. Although these assets are contractual receivables from the FDIC, there are no contractual interest rates. Additions to expected losses will require an increase to the allowance for loan losses and a corresponding increase to the FDIC indemnification assets. The corresponding accretion is recorded as a component of non-interest income on the Consolidated Statements of Income.

The following table summarizes the activity in the Company's FDIC indemnification asset during the periods indicated:

Other Bank Acquisitions – 2011

On September 30, 2011, the Company acquired Elgin State Bancorp, Inc. ("ESBI"). ESBI was the parent company of Elgin State Bank, which operated three banking locations in Elgin, Illinois. As part of this transaction, Elgin State Bank was merged into the Company's wholly-owned subsidiary bank, St. Charles Bank & Trust Company ("St. Charles"). St. Charles acquired assets with a fair value of approximately $263.2 million, including $146.7 million of loans, and assumed liabilities with a fair value of approximately $248.4 million, including $241.1 million of deposits. Additionally, the Company recorded goodwill of $5.0 million on the acquisition.

Wealth Management Acquisitions

On March 30, 2012, the Company's wholly-owned subsidiary, The Chicago Trust Company, N.A. ("CTC"), completed its previously announced acquisition of the trust operations of Suburban Bank & Trust Company ("Suburban"). Through this transaction, CTC acquired trust accounts having assets under administration of approximately $160 million, in addition to land trust accounts. The Company recorded goodwill of $1.8 million on the acquisition. Certain purchase price allocations for the trust operations of Suburban are preliminary. The final allocation is not expected to result in material changes.

On July 1, 2011, the Company acquired Great Lakes Advisors, Inc. ("Great Lakes Advisors"), a Chicago-based investment manager with approximately $2.4 billion in assets under management. The Company acquired assets with a fair value of approximately $26.0 million and assumed liabilities with a fair value of approximately $8.8 million. The Company recorded goodwill of $15.7 million on the acquisition.

Mortgage Banking Acquisitions

On April 13, 2011, the Company acquired certain assets and assumed certain liabilities of the mortgage banking business of River City Mortgage, LLC ("River City") of Bloomington, Minnesota. Licensed to originate loans in five states, and with offices in Minnesota, Nebraska and North Dakota, River City originated nearly $500 million in mortgage loans in 2010.

On February 3, 2011, the Company acquired certain assets and assumed certain liabilities of the mortgage banking business of Woodfield Planning Corporation ("Woodfield") of Rolling Meadows, Illinois. With offices in Rolling Meadows, Illinois and Crystal Lake, Illinois, Woodfield originated approximately $180 million in mortgage loans in 2010.

Purchased loans with evidence of credit quality deterioration since origination

Purchased loans acquired in a business combination are recorded at estimated fair value on their purchase date. Expected future cash flows at the purchase date in excess of the fair value of loans are recorded as interest income over the life of the loans if the timing and amount of the future cash flows is reasonably estimable ("accretable yield"). The difference between contractually required payments and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference and represents probable losses in the portfolio.

In determining the acquisition date fair value of purchased impaired loans, and in subsequent accounting, the Company aggregates these purchased loans into pools of loans by common risk characteristics, such as credit risk rating and loan type. Subsequent to the purchase date, increases in cash flows over those expected at the purchase date are recognized as interest income prospectively. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses.

The Company purchased a portfolio of life insurance premium finance receivables in 2009. These purchased life insurance premium finance receivables are valued on an individual basis with the accretable component being recognized into interest income using the effective yield method over the estimated remaining life of the loans. The non-accretable portion is evaluated each quarter and if the loans' credit related conditions improve, a portion is transferred to the accretable component and accreted over future periods. In the event a specific loan prepays in whole, any remaining accretable and non-accretable discount is recognized in income immediately. If credit related conditions deteriorate, an allowance related to these loans will be established as part of the provision for credit losses.
