Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies There have been no material changes to the significant accounting policies disclosed in the Company’s Annual Report on Form 10-K during the six months ended June 30, 2022, except for the adoption of the new lease accounting standard effective January 1, 2022, as discussed below. Leases In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2016-02, Leases (Topic 842). Topic 842 increases transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements for both lessees and lessors. The Company adopted the new standard effective January 1, 2022, electing to use the package of practical expedients permitted under the transition guidance which allows for the carry forward of historical lease classification for existing leases on the adoption date and does not require the assessment of existing lease contracts to determine whether the contracts contain a lease or initial direct costs. The Company also elected the practical expedient to not separate non-lease components from lease components and instead to account for each separate lease component and the non-lease components associated with that lease component as a single lease component for leases associated with office and laboratory space, manufacturing facilities, and equipment. Prior periods were not retrospectively adjusted. The adoption of this standard resulted in the recognition of operating lease right-of-use (ROU) assets in the amount of $3.3 million and operating lease liabilities in the amount of $5.4 million on the consolidated balance sheet, with a $2.1 million reclassification of deferred rent and tenant improvement allowances. There was no cumulative effect adjustment to the opening balance of accumulated deficit as of January 1, 2022. The adoption of this standard did not have an impact on the consolidated statements of operations or cash flows on the effective date. The Company leases office and laboratory space and equipment. In addition, the Company enters into manufacturing supply agreements with contract manufacturing organizations (CMO) and contract development and manufacturing organizations (CDMO) to manufacture clinical product candidate materials. Such agreements may include an embedded lease due to the exclusive use of identified manufacturing facilities and equipment that are controlled by the Company and for which the Company obtains substantially all the output. The evaluation of leases that are embedded in the Company’s CMO and CDMO agreements is complex and requires judgment. If a lease arrangement is determined to exist with a lease term of more than 12 months at the lease commencement date, an ROU asset and corresponding lease liability are recorded on the consolidated balance sheet at the lease commencement date based on the present value of fixed lease payments over the lease term. The lease commencement date, defined as the date on which the lessor makes the underlying asset available for use by the lessee and the date from which the Company is required to recognize lease expenses, may be different from the inception date of the contract. An ROU asset represents the right to control the use of an identified asset over the lease term and a lease liability represents the obligation to make lease payments arising from the lease. The Company uses the discount rate implicit in the lease, if available, or its incremental borrowing rate on the lease commencement date to determine the present value of lease payments. The lease terms used to calculate the ROU assets and related lease liabilities include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company expenses ROU assets acquired for research and development activities under Accounting Standards Codification (ASC) Topic 730, Research and Development, if they do not have an alternative future use, in research and development projects or otherwise. Leases are classified as either operating or finance leases based on the economic substance of the agreement. For operating leases, the Company recognizes lease expense related to fixed payments on a straight-line basis over the lease term. For finance leases, the Company recognizes the amortization of the ROU asset over the shorter of the lease term or useful life of the underlying asset. Interest accretion on the finance lease liabilities is recorded as interest expense. For both operating and finance leases, lease expense related to variable payments is recognized as incurred based on performance or usage in accordance with the contractual agreements. For short-term lease arrangements with a term of one year or less, the Company has elected to recognize the related lease payments on a straight-line basis over the lease term without recording related ROU assets and lease liabilities. The Company uses significant assumptions and judgment in evaluating its lease contracts and other agreements, including the determination of whether an agreement is or contains a lease, whether a change in the terms and conditions of a lease contract represent a new or modified lease, whether a lease represents an operating or finance lease, the discount rate used to determine the present value of lease obligations, and the term of a lease embedded in its manufacturing supply agreements.
