Item 14. Principal Accounting Fees and Services.
Audit and Non-Audit Fees
The following table represents aggregate fees billed or to be billed to us for the fiscal years ended December 31, 2016 and December 31, 2015 by KPMG LLP, our principal independent registered public accounting firm.
Year ended December 31,
All other fees
This category includes KPMG LLP’s audit of our annual consolidated financial statements and review of financial statements included in our quarterly reports on Form 10-Q. This category also includes advice on audit and accounting matters that arose during, or as a result of, the audit or review of interim financial statements and reimbursed expenses billed.
All fees described above were approved by our Audit Committee.
PRE-APPROVAL POLICIES AND PROCEDURES
The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services rendered by KPMG LLP, our independent registered public accounting firm. The Audit Committee pre-approves specified services in defined categories of audit services, audit-related services and tax services up to specified amounts, as part of the Audit Committee’s approval of the scope of the engagement of KPMG LLP or on an individual case-by-case basis before KPMG LLP is engaged to provide a service. The Audit Committee has determined that the rendering of the services other than audit services by KPMG LLP is compatible with maintaining the principal accountant’s independence.
