Accounting Changes and Error Corrections [Abstract]
Recently Adopted Accounting Standard	2. Recently Adopted Accounting Standard In February 2016, the FASB issued new guidance for lease accounting, which requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements. The new guidance establishes a right-of-use model (“ROU”) that requires a lessee to recognize a ROU asset and a lease liability on the balance sheet for all leases with a term longer than twelve months. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. For lessors, the guidance modifies the classification criteria and accounting for sales-type and direct financing leases. The Company adopted the new standard as of January 1, 2019, using the effective date as the date of initial application. As a result, financial information has not been updated and the disclosures required under the new standard have not been provided for dates and periods before January 1, 2019. The Company elected the ‘package of practical expedients’, which permits companies to not reassess under the new standard lease identification, lease classification and initial direct costs. The Company did not elect the use-of-hindsight or the practical expedient pertaining to land easements, the latter not being applicable. The adoption of the standard resulted in the recognition of ROU assets and lease liabilities of approximately $4,329,000 and $4,455,000, respectively, as of January 1, 2019. There was no cumulative effect of adopting this new guidance, and the standard did not have a material impact on the Company’s consolidated statements of operations or cash flows for the three and six months ended June 30, 2019.
Impact of recently issued accounting standards	15. Impact of Recently Issued Accounting Standards In August 2018, the Financial Accounting Standards Board (“FASB”) issued guidance which modifies the disclosure requirements on fair value measurements under Topic 820, Fair Value Measurements, including the consideration of costs and benefits . The new guidance is effective for all entities for annual and interim periods in fiscal years beginning after December 15, 2019, with early adoption permitted. It is required to be applied on a retrospective approach with certain elements being adopted prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. The Company has not yet determined the impact this new guidance will have on its consolidated financial statements and related disclosures. In June 2016, the FASB issued new guidance which will require measurement and recognition of expected credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new guidance is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. It is required to be applied on a modified-retrospective approach with certain elements being adopted prospectively. The Company does not expect the adoption of the new guidance will have a material impact on its consolidated financial statements and related disclosures. Other new pronouncements issued but not effective until after June 30, 2019 are not expected to have a material impact on the Company’s consolidated financial statements.
