Revenue from Contracts with Customers

, or ASU

2014

which converges the FASB and the International Accounting Standards Board standards on revenue recognition. Under ASU

2014

09,

a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In addition, ASU

2014

requires certain additional disclosures around the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The FASB has issued several amendments to the standard, including clarification on accounting for licenses of intellectual property, identifying performance obligations and other technical corrections. The Company adopted ASU

2014

January 1, 2018,

using the modified retrospective approach. The adoption of ASU

2014

did

not

have a material impact on the Company’s financial position, results of operations, equity or cash flows as of the adoption date or for the

six

months ended

June 30, 2018.

Recently Issued Accounting Pronouncements

February 2016,

the FASB issued ASU

2016

Leases

, or ASU

2016

02.

ASU

2016

requires lessees to reflect most leases on their balance sheets but recognize expenses on their income statements in a manner similar to current accounting. The guidance also eliminates real estate-specific provisions for all entities. The new guidance will be effective for the Company for annual and interim periods beginning after

December 15, 2018.

In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Early adoption is permitted. The adoption of ASU

2016

will result in an increase to the Company’s consolidated balance sheets for right-of-use assets and lease liabilities, and the Company is currently evaluating the other effects of adoption of ASU

2016

on the Company’s consolidated financial statements. This evaluation process includes reviewing all forms of leases, performing a completeness assessment over the lease population, and analyzing the practical expedients provided for in adopting ASU

2016

02.

the FASB issued ASU

Financial Instruments-Credit Losses

, or ASU

2016

13.

ASU

2016

requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. Under current U.S. GAAP, a company only considered past events and current conditions in measuring an incurred loss. Under ASU

2016

13,

the information that a company must consider is broadened in developing an expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss. The new guidance will be effective for the Company for annual and interim periods beginning after

December 15, 2019.

Early adoption is permitted for annual and interim periods beginning after

December 15, 2018.

The guidance is applied using a modified retrospective, or prospective approach, depending on a specific amendment. The Company is currently evaluating ASU

2016

and has

not

yet determined how it

may

impact its financial position, results of operations or related disclosures.

December 15, 2019.

Improvements to Nonemployee Share-Based Payment Accounting

, or ASU

2018

ASU

2018

2018

will be effective for the Company for fiscal years beginning after

December 15, 2018,

including interim periods within that fiscal year. Early adoption is permitted. The Company is currently evaluating ASU

2018

Under the U.S. Jumpstart our Business Startups Act, or the JOBS Act, emerging growth companies that become public can delay adopting new or revised accounting standards until such time as those standards apply to private companies. The Company irrevocably elected

not

to avail itself of this exemption from new or revised accounting standards and, therefore, it is subject to the same new or revised accounting standards as public companies that are

not

emerging growth companies.
