Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements. In 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)", which amends the existing standards for lease accounting, requiring lessees to recognize most leases on their balance sheets. The new standard establishes a right-of-use model that requires a lessee to recognize a right-of-use asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating. The standard is effective for interim and annual reporting periods beginning after December 15, 2018. The provisions of ASU 2016-02 are to be applied using a modified retrospective approach. In July 2018, the FASB issued ASU No. 2018-11, "Targeted Improvements - Leases (Topic 842)." This update provides an additional (and optional) transition method to adopt the new leases standard. Under this method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, the prior comparative period’s financials will remain the same as those previously presented. The Company adopted the new standard as of January 1, 2019 and it has also elected to adopt the package of practical expedients permitted in ASC 842. The amendments in ASU 2018-11 provide lessors with a practical expedient, by class of underlying asset, not to separate non-lease components from the associated lease component and, instead, to account for those components as a single component if the non-lease components otherwise would be accounted for under the new revenue guidance (Topic 606) and both of the following are met: 1. The timing and pattern of transfer of the non-lease component(s) and associated lease component are the same. 2. The lease component, if accounted for separately, would be classified as an operating lease. As the non-lease component(s) associated with the lease component is the predominant component of the combined component, the Company accounts for the combined component in accordance with Topic 606. The consolidated financial statements for the three and six months ended June 30, 2019 are presented under the new standard, while comparative year and other periods presented are not adjusted and continue to be reported in accordance with Topic 840, Leases.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements. In 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)", which amends the existing standards for lease accounting, requiring lessees to recognize most leases on their balance sheets. The new standard establishes a right-of-use model that requires a lessee to recognize a right-of-use asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating. The standard is effective for interim and annual reporting periods beginning after December 15, 2018.

The provisions of ASU 2016-02 are to be applied using a modified retrospective approach. In July 2018, the FASB issued ASU No. 2018-11, "Targeted Improvements - Leases (Topic 842)." This update provides an additional (and optional) transition method to adopt the new leases standard. Under this method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, the prior comparative period’s financials will remain the same as those previously presented. The Company adopted the new standard as of January 1, 2019 and it has also elected to adopt the package of practical expedients permitted in ASC 842.

The amendments in ASU 2018-11 provide lessors with a practical expedient, by class of underlying asset, not to separate non-lease components from the associated lease component and, instead, to account for those components as a single component if the non-lease components otherwise would be accounted for under the new revenue guidance (Topic 606) and both of the following are met:

1. The timing and pattern of transfer of the non-lease component(s) and associated lease component are the same.

2. The lease component, if accounted for separately, would be classified as an operating lease.

As the non-lease component(s) associated with the lease component is the predominant component of the combined component, the Company accounts for the combined component in accordance with Topic 606.

The consolidated financial statements for the three and six months ended June 30, 2019 are presented under the new standard, while comparative year and other periods presented are not adjusted and continue to be reported in accordance with Topic 840, Leases.
