Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recently Issued Accounting Standards	Accounting Standard Adopted in 2017 Effective January 1, 2017, the Company adopted ASU 2016-09, "Improvements to Employee Share-Based Accounting." ASU 2016-09 changed aspects of the accounting for share-based payment award transactions, including: (1) accounting for income taxes; (2) classification of excess tax benefits on the statement of cash flows; (3) forfeitures; (4) minimum statutory tax withholding requirements; and (5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. The recognition of excess tax benefits and tax deficiencies in the income statement was adopted prospectively. An income tax benefit of $1.1 million was recognized during the three months ended March 31, 2017 as a result of the adoption of ASU 2016-09. We expect the requirements of ASU 2016-09 to result in fluctuations in our effective tax rate from period to period based upon the timing of share-based award vestings. In connection with the adoption of ASU 2016-09, we elected to recognize forfeitures on stock-based compensation awards when they occur, instead of estimating forfeitures at the grant date of the awards and throughout the vesting period. The modified retrospective application of this change in accounting principle resulted in a cumulative adjustment charge to retained earnings of $420,000, net of income taxes. We elected to present the classification of excess tax benefits on the statement of cash flows using a prospective transition method and the prior period has not been adjusted. RECENTLY ISSUED ACCOUNTING STANDARDS In May 2014, the FASB issued ASU 2014-09, "Revenue Recognition (Topic 606): Revenue from Contracts with Customers." ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. The standard permits the use of either the retrospective or cumulative effect transition method. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which deferred the effective date of ASU 2014-09 to annual and interim periods beginning after December 15, 2017, while earlier application is permitted only for annual and interim periods beginning after December 31, 2016. The Company has completed the assessment phase of implementing this new standard. In the assessment phase, the Company determined which revenue streams are within the scope and those that are excluded from the scope of the new standard. Substantially all of the Company's revenues are excluded from the scope of the new standard. For the revenue streams determined to be within the scope of the new standard, the Company examined a sample of customer contracts to determine the appropriate accounting for those contracts under the new standard. The Company is currently evaluating the need for any accounting or operational changes related to implementing the requirements of the new standard. The Company will use the modified retrospective transition method and does not expect the provisions of ASU 2014-09 to have a material impact on its consolidated financial position or results of operations. The Company will adopt this standard effective January 1, 2018. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," which will significantly change the income statement impact of equity investments and the recognition of changes in fair value of financial liabilities when the fair value option is elected. For equity investments with readily determinable fair values, entities must measure these investments at fair value and recognize changes in fair value in net income. For equity investments without readily determinable fair values, entities have the option to either measure these investments at fair value or at cost, adjusted for changes in observable prices, minus impairment. Changes in measurement under either alternative must be recognized in net income. ASU 2016-01 will be effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted only for the provisions related to the recognition of changes in fair value of financial liabilities, which does not apply to the Company. The Company does not expect the provisions of ASU 2016-01 to have a material impact on its consolidated financial position or results of operations. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)," which, among other things, requires lessees to recognize most leases on-balance sheet, which will result in an increase in their reported assets and liabilities. Lessor accounting remains substantially similar to current U.S. GAAP. ASU 2016-02 supersedes Topic 840, Leases. ASU 2016-02 is effective for annual and interim periods in fiscal years beginning after December 15, 2018 and mandates a modified retrospective transition method for all entities. The Company is evaluating the effect that ASU 2016-02 will have on its financial statements and related disclosures. In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments," which significantly changes the way entities recognize impairment of many financial assets. Currently, the impairment model is based on incurred losses, and investments are recognized as impaired when there is no longer an assumption that future cash flows will be collected in full under the originally contracted terms. Under the current expected credit loss (CECL) model, the new standard requires immediate recognition of estimated credit losses expected to occur over the remaining life of the asset. The Company is reviewing software options to assist in meeting the requirements of ASU-2016-13. The Company is developing an implementation plan and is planning to engage a third-party vendor and commence early-stage model development in 2017. ASU 2016-13 is effective for interim and annual periods in fiscal years beginning after December 15, 2019. The Company is evaluating the effect that ASU 2016-13 will have on its consolidated financial position or results of operations. In August 2016, the FASB issued ASU 2016-15, "Classification of Certain Cash Receipts and Cash Payments," which addressed eight issues related to the statement of cash flows, including proceeds from the settlement of BOLI policies. ASU 2016-15 is effective for interim and annual periods in fiscal years beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. If an entity early adopts ASU 2016-15 in an interim period, adjustments should be reflected as of the beginning of the fiscal year that includes the interim period. An entity that elects early adoption must adopt all of the amendment in the same period. Entities should apply ASU 2016-15 using a retrospective transition method to each period presented. If it is impracticable for an entity to apply ASU 2016-15 retrospectively for some of the issues, it may apply the amendments for those issues prospectively as of the earliest date practicable. ASU 2016-15 will result in some changes in classification in the consolidated statements of cash flows, which the Company does not expect will be significant, and will not have any impact on its consolidated financial position or results of operations. In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory," which requires entities to recognize at the transaction date the income tax consequences of intercompany asset transfers other than inventory. ASU 2016-16 is effective for interim and annual periods in fiscal years beginning after December 15, 2017. Early adoption is permitted, but only at the beginning of an annual period for which no financial statements (interim or annual) have already been issued or made available for issuance. The Company is evaluating the effect that ASU 2016-16 will have on its financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business," which provides a new framework for determining whether transactions should be accounted for as acquisitions of assets or businesses. ASU 2017-01 is effective for annual periods in fiscal years beginning after December 15, 2018 and interim periods in fiscal years beginning after December 15, 2019. The Company does not expect ASU 2017-01 to have a material impact on its financial condition or results of operations. In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," which intends to simplify goodwill impairment testing by eliminating the second step of the analysis under which the implied fair value of goodwill is determined as if the reporting unit were being acquired in a business combination. ASU 2017-04 instead requires entities to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for any amount by which the carrying amount exceeds the reporting unit's fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit. ASU 2017-04 must be applied prospectively and is effective for the Company on January 1, 2020. Early adoption is permitted. The Company does not expect ASU 2017-04 to have a material impact on its financial condition or results of operations.
Basis of Presentation	Basis of Presentation Our interim condensed consolidated financial statements are prepared in accordance with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, certain disclosures accompanying annual consolidated financial statements are omitted. In the opinion of management, all significant intercompany accounts and transactions have been eliminated and adjustments, consisting solely of normal recurring accruals and considered necessary for the fair presentation of financial statements for the interim periods, have been included. The current period's results of operations are not necessarily indicative of the results that ultimately may be achieved for the year. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K.
Use of Estimates	Use of Estimates We have made a number of estimates and assumptions related to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these condensed consolidated financial statements in conformity with U.S. GAAP. Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowance for credit losses, the carrying value of intangible assets, the realization of deferred tax assets, and the fair value estimates of assets acquired and liabilities assumed in acquisitions. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.
Reclassification, Policy	Reclassifications Certain prior period amounts have been reclassified to conform to the current period’s presentation format. Regarding time deposits disclosures, we previously presented the categories as: (1) under $100,000, and (2) $100,000 or more, but now are using the current FDIC insurance limit of $250,000 and presenting the categories as: (1) $250,000 and under, and (2) over $250,000.
