Compensation: Compensation is primarily comprised of accrued employee salaries, taxes and benefits.

Severance and restructuring accruals: On December 4, 2018, the Company and Jikun Kim, the Company's former Chief Financial Officer, entered into a Separation and General Release Agreement (the “Separation Agreement”) pursuant to which the Company and Mr. Kim agreed that he would cease service with the Company effective as of December 31, 2018 (the “Separation Date”). The Separation Agreement provided for, among other things, the continuation of his base salary for a period of two months following the Separation Date and a lump sum payment of $22,875 in lieu of any cash bonus payment under the Company’s Fiscal Year 2018 Bonus Plan, in each case subject to his execution and non-revocation of a general release agreement releasing the Company from any liability or obligation to him and compliance with certain confidentiality, non-solicitation and other restrictive covenants as provided in the Separation Agreement. Mr. Kim’s outstanding equity awards that remained unvested as of the Separation Date were cancelled and terminated. The Company recorded a charge of approximately $0.1 million in the three months ended December 31, 2018 related to this Separation Agreement.

Our severance and restructuring-related accruals specifically relate to the separation agreement discussed above and non-cancelable obligations associated with an abandoned leased facility. Expense related to severance and restructuring accruals is included in selling, general, and administrative expense on our statements of operations and comprehensive income.
