Accounting Policies [Abstract]
Changes in Accounting Principles	Except for the changes below, the Company has consistently applied the accounting principles to all periods presented in these condensed consolidated financial statements. The Company adopted Topic 842, Leases with a date of the initial application of January 1, 2019. We adopted Topic 842 as of January 1, 2019, using the alternative transition method that allowed us to recognize a cumulative-effect adjustment to the opening balance of retained earnings at the beginning of the period of adoption. We used the package of practical expedients permitted under the transition guidance that allowed us to not reassess: (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases and (3) initial direct costs for any expired or existing leases. We elected the practical expedient that allows lessees to treat the lease and non-lease components of leases as a single lease component. Additionally, we elected the hindsight practical expedient to determine the reasonably certain lease terms for existing leases. The adoption of Topic 842 did not have a material adjustment to the opening balance of retained earnings. The adoption of Topic 842 had a material impact on our condensed consolidated balance sheet due to the recognition of right-of-use (“ROU”) assets and lease liabilities. As a result of the adoption of the standard, the Company recognized ROU assets and lease liabilities of $1,088,000 as of January 1, 2019. The adoption of Topic 842 did not have a material impact on our condensed consolidated statement of operations or our condensed consolidated statement cash flows.
