On January 1, 2019, the Company adopted the new lease guidance using a modified retrospective transition method applied to those leases which were not completed as of January 1, 2019. Results for reporting periods beginning after December 31, 2018 are presented under the new guidance, while prior period comparative amounts are not adjusted and continue to be reported in accordance with historical guidance. The Company applied the new standard using the package of practical expedients permitted under the transition guidance where the Company:

In addition, the Company elected the hindsight practical expedient to determine the lease term for existing leases.

The resulting impact, as of the adoption date, to the consolidated balance sheet of applying the new guidance in 2019 versus the prior guidance was an increase to right-of-use assets of $152.2 million, a decrease to other assets of $0.3 million, an increase to total assets of $151.9 million, an increase to short-term lease liabilities of $14.1 million, a decrease to accrued expenses and other current liabilities of $0.5 million, an increase to total current liabilities of $13.5 million, an increase to long-term lease liabilities of $164.8 million, a decrease to deferred rent, net of current portion, of $26.4 million and an increase to total liabilities of $151.9 million. There was no impact to stockholders’ equity or the consolidated statements of operations as a result of adopting the new guidance. There was no impact to total operating or financing cash flows of applying the new guidance in 2019 versus the prior guidance other than renaming or adding line items to the statements of cash flows to conform to the accounting for, and presentation of, the new standard.

The Company determines if an arrangement contains a lease at inception and does not separate lease and non-lease components of an arrangement determined to contain a lease. Operating and finance leases with a duration of less than 12 months are excluded from right-of-use-assets and lease liabilities and related expense is recorded as incurred.

The Company leases its office facilities under non-cancelable operating leases that expire at various dates through May 2031. Certain leases contain optional termination dates. The table below only considers lease obligations through the optional termination dates, as the Company is not reasonably certain to extend lease agreements beyond those dates.
