Summary of Significant Accounting Policies
 
Interim financial statements
 
We have prepared the accompanying condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States (US GAAP) for interim financial information and with the instructions to Form
10
-Q and Regulation S-
X
of the Securities and Exchange Commission (SEC). Accordingly, they do
not
include all of the information and footnotes required by US GAAP for complete financial statements. These condensed consolidated financial statements reflect all adjustments consisting of normal recurring accruals which, in the opinion of management, are necessary to present fairly our consolidated financial position, consolidated results of operations, consolidated statement of shareholders' equity and consolidated cash flows for the periods and as of the dates presented. Our fiscal year ends on
December 31.
The condensed consolidated balance sheet as of
December 31, 2019
was derived from our audited consolidated financial statements. These condensed consolidated financial statements should be read in conjunction with our annual consolidated financial statements and the notes thereto. The nature of our business is such that the results of any interim period
may
not
be indicative of the results to be expected for the entire year.
 
Cash and
cash e
quivalents
 
The Company considers all bank deposits, including money market funds, and other investments, purchased with an original maturity to the Company of
three
months or less, to be cash and cash equivalents. The carrying amount of our cash equivalents approximates fair value due to the short maturity of the investments.
 
Concentration of credit risk
 
Financial instruments that potentially expose the Company to concentration of credit risk consist primarily of cash, cash equivalents and marketable securities. The Company maintains its cash balances primarily with
two
financial institutions. These balances generally exceed federally insured limits. The Company has
not
experienced any losses in such accounts and believes it is
not
exposed to any significant credit risk in cash and cash equivalents. The Company believes that the credit risk related to marketable securities is limited due to the adherence to an investment policy focused on the preservation of principal.
 
Marketable securities
 
The Company's marketable securities typically consist of obligations of the United States government and its agencies, investment grade corporate obligations and bank certificates of deposit, which are classified as available-for-sale and included in current assets as they are intended to fund current operations. Securities are valued based on market prices for similar assets using
third
party certified pricing sources. Available-for-sale securities are carried at fair value with unrealized gains and losses reported as a component of shareholders' equity in accumulated other comprehensive income (loss). The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization or accretion is included in interest income. Realized gains and losses, if any, are calculated on the specific identification method and are included in other income in the condensed consolidated statements of operations.
 
Available-for-sale securities are reviewed for possible impairment at least quarterly, or more frequently if circumstances arise that
may
indicate impairment. When the fair value of the securities declines below the amortized cost basis, impairment is indicated and it must be determined whether it is other than temporary. Impairment is considered to be other than temporary if the Company: (i) intends to sell the security, (ii) will more likely than
not
be forced to sell the security before recovering its cost, or (iii) does
not
expect to recover the security's amortized cost basis. If the decline in fair value is considered other than temporary, the cost basis of the security is adjusted to its fair market value and the realized loss is reported in earnings. Subsequent increases or decreases in fair value are reported as a component of shareholders' equity in accumulated other comprehensive income (loss). There were
no
other-than-temporary unrealized losses as of
June 30, 2020.
 
Fair value measurements
 
Under the authoritative guidance for fair value measurements, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
 
The hierarchy is broken down into
three
levels defined as follows:
 
Level
1
Inputs
— quoted prices in active markets for identical assets and liabilities
Level
2
Inputs
— observable inputs other than quoted prices in active markets for identical assets and liabilities
Level
3
Inputs
— unobservable inputs
 
As of
June 30, 2020,
the Company believes that the carrying amounts of its other financial instruments, including amounts receivable, accounts payable and accrued liabilities, approximate their fair value due to the short-term maturities of these instruments. See Note
4,
titled “
Marketable Securities
” for additional information.
