The Company’s matching contribution for the year ended December 31, 2012 was 50% of the first 6% of a participant’s contributions.
For the years ended December 31, 2014, 2013 and 2012, the Company contributed approximately $6.5 million, $6.0 million and $4.4 million to the plan, respectively.
Accounting Standards Updates—In April 2014, the Financial Accounting Standards Board (the “FASB”) issued additional guidance on reporting discontinued operations.
Under this guidance, only disposals representing a strategic shift in operations would be presented as discontinued operations.
This guidance requires expanded disclosure that provides information about the assets, liabilities, income and expenses of discontinued operations.
Additionally, the guidance requires additional disclosure for a disposal of a significant part of an entity that does not qualify for discontinued operations reporting.
This guidance is effective for reporting periods beginning on or after December 15, 2014, with early adoption permitted for disposals or classifications of assets as held-for-sale that have not been reported in financial statements previously issued or available for issuance.
The Company chose to early adopt this guidance during the year ended December 31, 2014 and the adoption did not have a material effect on the Company’s financial statements.
In May 2014, the FASB issued new revenue recognition guidance, which requires an entity to recognize revenue in an amount that reflects the consideration to which the entity expects to be entitled in exchange for the transfer of promised goods or services to customers.
The standard will replace most existing revenue recognition guidance in GAAP and will become effective on January 1, 2017.
The standard permits the use of either the retrospective or cumulative effect transition method, and leases are not included in the scope of this standard.
The Company is evaluating the impact this standard may have on its financial statements.2.

Many of our nonfinancial institution competitors have fewer regulatory constraints, broader geographic service areas, greater capital, and, in some cases, lower cost structures.
In addition, competition for quality customers has intensified as a result of changes in regulation, advances in technology and product delivery systems, consolidation among financial service providers, bank failures, and the conversion of certain former investment banks to bank holding companies.
Financial Technology, or FinTech, startups are emerging in key areas of banking.
In response, we are monitoring activity in marketplace lending along with businesses engaged in money transfer, investment advice, and money management tools.
Our strategy involves assessing the marketplace, determining our near term plan, while developing a longer term approach to effectively service our existing customers and attract new customers.
This includes evaluating which products we develop inhouse, as well as evaluating partnership options where applicable.
