statistics (such as home sales and new building permits). In addition, since early- to mid-2009, we have seen an improvement in our asset quality metrics. In particular, since early 2012, we have generally experienced a decline in non-performing assets, lower levels of new loan defaults, and reduced levels of loan net charge-offs.
Recent Developments. On December 22, 2017, President Donald Trump signed into law “H.R. 1”, also known as the “Tax Cuts and Jobs Act”, which among other things, reduced the federal corporate income tax rate to 21% effective January 1, 2018. As a result, we concluded that our deferred tax assets, net (“DTA”) had to be remeasured. Our DTA represents expected corporate tax benefits anticipated to be realized in the future. The reduction in the federal corporate income tax rate reduces these anticipated future benefits. The remeasurement of our DTA at December 31, 2017 resulted in a reduction of these net assets and a corresponding increase in income tax expense of $6.0 million that was recorded in the fourth quarter of 2017.
On December 4, 2017, we entered into an Agreement and Plan of Merger with TCSB Bancorp, Inc. (“TCSB”) (the “Merger Agreement”) providing for a business combination of IBCP and TCSB. The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, TCSB will be merged with and into IBCP, with IBCP as the surviving corporation (the “Merger”). In addition, IBCP intends to consolidate Traverse City State Bank, TCSB's wholly-owned subsidiary bank, with and into Independent Bank (with Independent Bank as the surviving institution).
Subject to the terms and conditions of the Merger Agreement, we will pay aggregate Merger consideration of approximately $63.2 million in IBCP common stock or stock options for all of the shares of TCSB common stock and TCSB stock options issued and outstanding immediately before the effective time of the Merger. The Merger consideration is subject to adjustment in certain limited circumstances, as set forth in the Merger Agreement.
Completion of the Merger is subject to certain closing conditions. These include, among others, (i) in the case of both parties, receipt of the requisite approval of TCSB's shareholders, receipt of required regulatory approvals, the absence of any law or order prohibiting completion of the Merger and the absence of a material adverse effect (as defined in the Merger Agreement), and (ii) in the case of IBCP, the consolidated shareholders' equity of TCSB must be at least $33 million (subject to adjustment as provided in the Merger Agreement) as of the final statement date (as defined in the Merger Agreement). The Merger Agreement provides certain termination rights for both IBCP and TCSB and further provides that, upon termination of the Merger Agreement under certain circumstances, TCSB will be obligated to pay IBCP a termination fee of approximately $2.5 million. Currently, we anticipate that the Merger will be effective on or about April 1, 2018. Our 2017 non-interest expenses include $0.3 million of costs incurred through December 31, 2017 related to the Merger.
Effective on January 1, 2017, we adopted the fair value accounting method for capitalized mortgage loan servicing rights. The adoption of this accounting method resulted in the following changes to the January 1, 2017 beginning balances: an increase in capitalized mortgage loan servicing rights of $0.54 million; a decrease in deferred income taxes of $0.19 million and a decrease in our accumulated deficit of $0.35 million. See note #1 to the Consolidated Financial Statements.
On December 30, 2016, the Bank and its wholly-owned subsidiary, Mepco Finance Corporation (“Mepco”), entered into an Asset Purchase Agreement (“APA”) with Seabury Asset Management LLC (“Seabury”). Pursuant to the terms of the APA, we sold our payment plan processing business, payment plan receivables, and certain other assets to Seabury, who also assumed certain liabilities of Mepco. These assets and liabilities were categorized as “held for sale” in the December 31, 2016 Consolidated Statement of Financial Condition. We also recorded a $0.32 million loss related to the sale of these assets in the fourth quarter of 2016. This transaction closed on May 18, 2017, with an effective date of May 1, 2017. As a result of the closing, Mepco sold $33.1 million of net payment plan receivables, $0.5 million of commercial loans, $0.2 million of furniture and equipment and $1.6 million of other assets to Seabury, who also assumed $2.0 million of specified liabilities. Mepco was renamed IB Holding Company in May 2017 and was liquidated on June 30, 2017, with the remaining assets and liabilities transferred to the Bank. We do not believe that the sale of the Mepco business and assets will have a significant impact on our future overall financial condition or results of operations.
In the fourth quarter of 2016, we reached a tentative settlement regarding litigation initiated against the Bank in Wayne County, Michigan Circuit Court. The Court issued a preliminary approval of this settlement in the first quarter of 2017 and a final approval of this settlement in January 2018. This litigation concerned the Bank’s checking account transaction sequencing during a period from February 2009 to June 2011. Under the terms of the settlement, we agreed to pay $2.2 million and we are also responsible for class notification costs and certain other expenses
