Basis of presentation and Principles of Consolidation | |
The accompanying unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial reporting. However, certain information or footnote disclosures normally included in complete financial statements prepared in accordance with U.S. GAAP have been condensed, or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). In the opinion of the Company's management, the unaudited statements in this Quarterly Report on Form 10-Q include all normal and recurring adjustments necessary for the fair statement of the results for the interim periods presented. The results for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2014. | |
The condensed consolidated financial statements as of and for the three months ended March 31, 2014 and 2013 included in this Quarterly Report on Form 10-Q are unaudited. The balance sheet as of December 31, 2013 is derived from the audited financial statements as of that date. The accompanying statements should be read in conjunction with the audited financial statements and related notes, together with Management's Discussion and Analysis of Financial Condition and Results of Operations, contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2013 filed with the SEC on March 31, 2014 (the "2013 Annual Report"). | |

At December 31, 2013 and March 31, 2014, Heat held a 92.5% controlling interest in Heat I and accounts for its less than 100% interest in the unaudited condensed consolidated financial statements in accordance with U.S. GAAP. Accordingly, the Company presents non-controlling interests as a component of stockholders' equity (deficit) on its condensed consolidated balance sheets, condensed statement of stockholders equity (deficit), and reports non-controlling interest net loss under the heading "net loss - non-controlling interest" in the condensed consolidated statements of operations. In June 2012, the Company sold its entire 92.5% interest in Heat II. The operations of Heat II through June 25, 2012, including fiscal year 2012 and inception to date, are presented in the accompanying condensed consolidated statements of operations as a loss from discontinued operations. |

2. Fair Value of Financial Instruments | ||||||||||||||
The carrying amount of certain of the Company's financial instruments, including cash and cash equivalents, prepaid expenses and other current assets, deposits, accounts payable and accrued expenses and other payables approximate fair value due to their short maturities. | ||||||||||||||
As a basis for determining the fair value of certain of the Company's financial instruments, the Company utilizes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: | ||||||||||||||
Level I - Observable inputs such as quoted prices in active markets for identical assets or liabilities. | ||||||||||||||
Level II - Observable inputs, other than Level I 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 III - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. | ||||||||||||||
This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. The Company's financial instruments that are measured at fair value on a recurring basis consist only of the stock warrants liability at March 31, 2014 and December 31, 2013. Prior to exercise, the stock warrant liability was recorded at fair value based on ASC 480-10 and ASC 815-40-15 and the carrying value was remeasured every quarter with the adjustment recognized in earnings. Upon the cashless exercise of these warrants in January and February 2014, the sum of the fair value of the exercised warrants were credited to additional paid in capital and the liability was eliminated. | ||||||||||||||
The change in the fair value of the Level III stock warrants liability is summarized below: | ||||||||||||||

3. Income Tax | |
Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. | |
In accordance with FASB ASC 740, Accounting for Income Taxes, the Company reflects in the accompanying unaudited condensed consolidated financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered 'more-likely-than-not' that the position taken will be sustained by a taxing authority. As of March 31, 2014 and December 31, 2013, the Company had no unrecognized income tax benefits and correspondingly there is no impact on the Company's effective income tax rate associated with these items. The Company's policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying statements of income. As of March 31, 2014 and December 31, 2013, the Company had no such accruals. |

Investments - Investments in certain securities may be classified into three categories: | |||||||||||||
· | |||||||||||||
Held-to-maturity - Debt securities that the Company has the positive intent and ability to hold to maturity are reported at amortized cost. | |||||||||||||
· | |||||||||||||
Trading securities - Debt and equity securities that are bought and held principally for the purpose of selling in the near term are reported at fair value with unrealized gains and losses included in earnings. | |||||||||||||
· | |||||||||||||
Available-for-sale - Debt and equity securities not classified as either securities held-to-maturity or trading securities are reported at fair value with unrealized gains or losses excluded from earnings and reported as a separate component of stockholders' equity. | |||||||||||||
The Company reassesses the appropriateness of the classification of its investments at the end of each reporting period. The Company has determined that its debt securities should be classified as held-to-maturity as of March 31, 2014 and December 31, 2013. This classification was based upon management's determination that it has the positive intent and ability to hold the securities until their maturity dates, as the underlying cash invested in these securities is not required for current operations. Investments consist of short-term FDIC insured certificates of deposit, commercial paper rated A1/P1 or above and corporate notes and bonds rated A and above carried at amortized cost using the effective interest method. | |||||||||||||
The following table summarizes information about short term investments at March 31, 2014: | |||||||||||||

As of March 31, 2014, the estimated fair value of the investments was less than the amortized cost. Because management has the positive intention and ability to hold the investments until their maturity dates, these unrealized losses were not recorded in the accompanying unaudited condensed consolidated financial statements. | |||||||||||||

Basic and diluted net loss per common share is calculated by dividing net loss applicable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. The Company's potentially dilutive shares, which include convertible preferred stock, outstanding stock options, warrants and unvested restricted stock are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive.

The preferred stock warrants converted into warrants to purchase common stock upon the completion of the initial public offering in July 2013. In January and February 2014, all 20,549 warrants were exercised in cashless transactions that resulted in the issuance of 8,065 shares of common stock. | ||||||||
The remaining common stock warrants are held by third parties in connection with prior private placements of our equity securities. In February 2014, 15,218 warrants were exercised in cashless transactions that resulted in the issuance of 14,318 shares of common stock. | ||||||||
In connection with our public offering we issued common stock warrants to the underwriters for 125,000 shares of common stock issuable at $12.50 per share upon exercise. The warrants have a ten-year life and expire on July 29, 2023. | ||||||||
Reverse Stock Split | ||||||||
In May 2013, the Company's board of directors and stockholders approved a 1-for-2.3 reverse stock split of the Company's common stock. The reverse stock split became effective on May 29, 2013. All share and per share amounts in the accompanying condensed consolidated financial statements have been retroactively adjusted for all periods presented to give effect to the reverse stock split, including reclassifying an amount equal to the increase in par value to additional paid-in capital. |

The weighted average grant-date fair value of stock options granted during the three months ended March 31, 2014 was $7.90. The fair value of each stock option is estimated on the date of grant using the Black-Scholes-Merton option pricing model with the following assumptions for stock options granted during the three months ended March 31, 2014: | |||||||||||||||||||||||||
Dividend yield | 0 | % | |||||||||||||||||||||||
Expected volatility | 110 | % | |||||||||||||||||||||||
Risk-free interest rate | 2.21 | % | |||||||||||||||||||||||
Expected lives (years) | 6.5 | ||||||||||||||||||||||||
The risk-free interest rate is based on U.S. Treasury interest rates at the time of the grant whose term is consistent with the expected life of the stock options. The Company used an average historical stock price volatility based on an analysis of reported data for a peer group of comparable companies that have issued stock options with substantially similar terms, as the Company did not have any trading history for its common stock. Expected term represents the period that the Company's stock option grants are expected to be outstanding. The Company elected to utilize the "simplified" method to value stock option grants. Under this approach, the weighted-average expected life is presumed to be the average of the vesting term and the contractual term of the option. | |||||||||||||||||||||||||
Expected dividend yield was considered to be 0% in the option pricing formula since the Company had not paid any dividends and had no plans to do so in the future. The forfeiture rate was considered to be none insofar as the historical experience of the Company is very limited. As required by ASC 718, the Company will adjust the estimated forfeiture rate based upon actual experience. | |||||||||||||||||||||||||
The Company recognized $169,112 and $26,793 in stock-based compensation expense for the three months ended March 31, 2014 and 2013, respectively for the Company's stock option awards. | |||||||||||||||||||||||||

Preferred Stock | |
In March 2013, the Company sold an aggregate of 1,891,419 shares of the Company's Series B-1 Preferred Stock for gross proceeds of approximately $5.0 million in the Series B Preferred Stock private placement. All shares of the Series B Preferred Stock, together with accrued dividends, automatically converted into shares of the Company's common stock upon the consummation of the Company's initial public offering on July 29, 2013. In addition, the investors in the Series B-1 Preferred Stock were issued shares of the Company's common stock having a value based upon the initial public offering price of $361,668 and the Company's obligation to issue, and the investors, obligation to purchase, Series B-2 Preferred Stock and warrants upon fulfillment of certain conditions specified in the Company's stock purchase agreement dated as of March 25, 2013 entered into in connection with such private placement (the "Stock Purchase Agreement") terminated. The issuance of common stock to the Series B-1 Preferred stockholders totaling $361,668 has been accounted for as a preferred stock dividend, and as a result, has been included as an expense attributable to common stockholders in the Company's condensed consolidated statements of operations. | |
Initial Public Offering | |
On July 29, 2013, the Company sold 2,500,000 shares of common stock at a public offering price of $10.00 per share upon the closing of the Company's initial public offering ("IPO") with gross proceeds of $25 million and net proceeds of $22.4 million. On August 15, 2013, the Company sold an additional 100,000 shares of common stock at a public offering price of $10.00 per share pursuant to the partial exercise of the over-allotment option granted to the underwriters resulting in additional gross proceeds to the Company of $1,000,000 and additional net proceeds of $930,000. On September 6, 2013, the Company sold an additional 100,000 shares of common stock at a public offering price of $10.00 per share pursuant to the partial exercise of the over-allotment option granted to the underwriters resulting in additional gross proceeds to the Company of $1,000,000 and additional net proceeds of $930,000. The total gross proceeds raised from the offering and over-allotment option were $27,000,000, before underwriting discounts, commissions and other offering expenses payable by the Company. The total net proceeds from the offering were approximately $24.3 million. Upon the closing of the IPO, all shares of the Company's then-outstanding preferred stock automatically converted into an aggregate of 1,696,683 shares of common stock. In addition, upon the closing of the IPO, the Company issued an additional 36,167 shares of common stock to the Series B Preferred Stockholders as a Preferred Stock dividend. At that time, the Company's obligation to issue, and the Series B Preferred Stockholders' obligation to purchase Series B-2 Preferred Stock under the Stock Purchase Agreement terminated. |
