6. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
In accordance with ASC Topic 820, the Company measures cash and cash equivalents and marketable debt and equity securities at fair value on a recurring basis. Other investments are measured at fair value on a nonrecurring basis.
 
The following are the major categories of assets and liabilities measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017, using quoted prices in active markets for identical assets (Level 1) and significant other observable inputs (Level 2). For the periods presented, there were no major assets measured at fair value on a recurring basis where significant unobservable inputs were used (Level 3):
 
Assets and liabilities measured at fair value on a recurring basis are summarized below:
