Operating Lease Commitment

In September 2016, the Company amended its commercial lease for office space to expand into an additional 4,088 square feet of office space within the existing building for an aggregate total of 10,414 square feet of leased office space (“September 2016 Amendment”). The Company began occupying this space in early November 2016 and the final lease payment was to be due in January 2021. Additionally, the September 2016 Amendment required an increase in the standby letter of credit to $50,000 (See Note 4). The September 2016 Amendment was terminated upon the commencement date of the August 2017 Lease Agreement discussed below.

On August 21, 2017, the Company entered into a lease agreement (“August 2017 Lease Agreement”) with the same landlord, pursuant to which the Company agreed to lease 32,733 square feet of office space (“Leased Premises”). The initial term of the August 2017 Lease Agreement is for a period of seven years which began with the Company’s occupancy of the Leased Premises in February 2018. The base rent for the Leased Premises ranges from approximately $470,000 for the first year to approximately $908,000 for the seventh year. Per the terms of the August 2017 Lease Agreement, the landlord agreed to reimburse the Company for $1,080,189 of leasehold improvements. The reimbursements have been deferred and will be recognized as a reduction of rent expense over the term of the lease. Additionally, the August 2017 Lease Agreement required a standby irrevocable letter of credit of $400,000, which may be reduced, if the Company is not in default under the August 2017 Lease Agreement, to $300,000 and $200,000 on the third and fourth anniversary of the commencement date, respectively. The Company entered into an unsecured letter of credit for $400,000 in connection with the August 2017 Lease Agreement for which it incurred interest expense of $1,774 and $3,549 for the three and six months ended June 30, 2018, respectively.

The Company records the total rent payable during the lease term on a straight-line basis over the term of the lease and records the difference between the rents paid and the straight-line rent as deferred rent, which is classified in deferred rent, noncurrent in the Company’s balance sheet as of June 30, 2018 and December 31, 2017.

Pursuant to the terms of the Company’s non-cancelable lease agreements in effect at June 30, 2018, the future minimum rent commitments are as follows:

Total rent expense for the three months ended June 30, 2018 and 2017 was $147,752 and $58,508, respectively. Total rent expense for the six months ended June 30, 2018 and 2017 was $294,743 and $117,016, respectively.
