Summary of Significant Accounting Policies [Abstract]

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in Operating Lease Right-of-Use Assets, Operating Lease Liabilities - Current and Operating Lease Liabilities - Non-Current in our Condensed Consolidated Balance Sheets. The Company does not have any leases that meet the finance lease criteria.

Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company's leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The operating lease right-of-use asset also includes any lease payments made in advance and any accrued rent expense balances. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Earnings Per Share, Policy [Policy Text Block]

Earnings per Common Share

Basic earnings per common share is computed by dividing net income by weighted average common shares outstanding for the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted. Common equivalent shares are excluded from the determination of diluted earnings per share in periods in which they have an anti-dilutive effect.

The following table sets forth the computation of basic and diluted earnings per share:



	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Net income	$	14,280	$	11,463	$	26,367	$	21,631
Weighted average shares outstanding:
Basic	19,120		18,934		19,062		18,880
Effect of dilutive securities:
Restricted stock units	202		250		300		355
Performance stock units	109		144		169		153
Diluted	19,431		19,328		19,531		19,389
Basic earnings per share	$	0.75	$	0.61	$	1.38	$	1.15
Diluted earnings per share	$	0.73	$	0.59	$	1.35	$	1.12

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Financial Accounting Standards

On January 1, 2019, the Company adopted Accounting Standards Update ("ASU") No. 2016-02, Leases, ASU No. 2018-10, Codification Improvements to Topic 842 (Leases) and ASU No. 2018-11, Targeted Improvements to Topic 842 (Leases). The guidance is intended to increase transparency and comparability among companies for leasing transactions, including a requirement for companies that lease assets to recognize on their balance sheets the assets and liabilities for the rights and obligations created by those leases. The guidance also provides for disclosures that allow the users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases.

The Company adopted the guidance on January 1, 2019 using the modified retrospective method without restatement of comparative periods. As such, periods prior to the date of adoption are presented in accordance with ASC 840 - Leases. The Company utilized the available practical expedient that allowed for the Company to not reassess whether existing contracts contain a lease under the new definition of a lease, lease classification for existing leases and whether previously capitalized initial direct costs would qualify for capitalization under the new guidance.

The adoption of this guidance had a material impact on the Condensed Consolidated Balance Sheet as of June 30, 2019 due to the recognition of equal right-of-use assets and lease liabilities for the Company's portfolio of operating leases. The right-of-use asset balance was then adjusted by the reclassification of pre-existing prepaid and accrued rent balances from other line items within the Condensed Consolidated Balance Sheet. The adoption had an immaterial impact on the Condensed Consolidated Statement of Comprehensive Income and Condensed Consolidated Statement of Cash Flows for the three and six months ended June 30, 2019. The adoption had no impact on the Condensed Consolidated Statement of Changes in Stockholders' Equity for the three and six months ended June 30, 2019.

Additional information and disclosures required by the new standard are contained in Note 6, Leases.

On January 1, 2019, the Company adopted ASU No. 2018-02, Income Statement - Reporting Comprehensive Income, which is intended to improve the usefulness of information reported as a result of the Tax Cuts and Jobs Act. The new guidance allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The adoption of this guidance did not have an impact on the Company's consolidated financial statements.
