Fair Value Measurements
 
A fair value hierarchy has been established that requires the Company to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value. The fair value hierarchy describes
three
levels of inputs that
may
be used to measure fair value:
 
 
Level
1
Quoted prices in active markets for identical assets or liabilities.
 
 
Level
2
Observable inputs other than Level
1
prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are
not
active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
 
Level
3
Unobservable inputs that are supported by little or
no
market activity and that are significant to the fair value of the assets or liabilities.
 
The following table sets forth the financial assets and liabilities that were measured at fair value on a recurring basis at
December 31, 2017
and
June 30, 2017,
by level within the fair value hierarchy. The assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.
 
The Company
’s short-term investments have been classified as Level
2,
which have been initially valued at the transaction price and subsequently revalued, at the end of each reporting period, utilizing a
third
party pricing service. The pricing service utilizes industry standard valuation models and observable market inputs to determine value that include surveying the bond dealer community, obtaining benchmark quotes, incorporating relevant trade data, and updating spreads daily. There have been
no
transfers of assets or liabilities between the fair value measurement classifications.

Cash equivalents consist primarily of money market funds
, corporate notes and commercial paper with original maturities of
90
or fewer days when purchased. Short-term investments consist of certificates of deposit, corporate securities, U.S. Treasury securities and
U.S. agency securities, classified as available-for-sale and have maturities less than
365
days from the date of acquisition.

As of
December 31, 2017
and
June 30, 2017,
the Company had investments in an unrealized gain (loss) position below material disclosure thresholds in the table above. The Company determined that the unrealized gains and losses on these investments were temporary in nature and expected the security to mature at its stated maturity principal. All available-for-sale securities held at
December 31, 2017,
will mature in less than
one
year.
The fair value of cash, accounts receivable, accounts payable and accrued liabilities approximate their carrying value because of the short-term nature of these financial instruments at
December 31
,
2017
and
June 30, 2017,
respectively
. The fair value of the Company’s short-term note payable, which is measured using Level
2
inputs, approximates book value, at
December 31
,
2017
and
June 30, 2017.
