	Balance as of December 31, 2018			Net Change			Balance as of June 30, 2019
Foreign currency translation adjustment ("CTA") loss	$	(998,603	)	$	(56,585	)	$	(1,055,188	)

Accumulated other comprehensive loss attributable to Equinix	$	(945,702	)	$	(12,741	)	$	(958,443	)


⁽¹⁾	Refer to Note 6 for a discussion of the amounts reclassified from accumulated other comprehensive loss to net income.

⁽²⁾

The Company has a defined benefit pension plan covering all employees in one country where such plan is mandated by law. The Company does not have any defined benefit plans in any other countries. The unamortized gain (loss) on defined benefit plans includes gains or losses resulting from a change in the value of either the projected benefit obligation or the plan assets resulting from a change in an actuarial assumption, net of amortization.

Changes in foreign currencies can have a significant impact to the Company's consolidated balance sheets (as evidenced above in the Company's foreign currency translation loss), as well as its consolidated results of operations, as amounts in foreign currencies are generally translated into more U.S. Dollars when the U.S. Dollar weakens or less U.S. Dollars when the U.S. Dollar strengthens. As of June 30, 2019, the U.S. Dollar was generally stronger relative to certain of the currencies of the foreign countries in which the Company operates as compared to December 31, 2018. This overall strengthening of the U.S. Dollar had an overall unfavorable impact on the Company's condensed consolidated financial position because the foreign denominations translated into less U.S. Dollars as evidenced by an increase in foreign currency translation loss for the six months ended June 30, 2019 as reflected in the above table. In future periods, the volatility of the U.S. Dollar as compared to the other currencies in which the Company operates could have a significant impact on its condensed consolidated financial position and results of operations including the amount of revenue that the Company reports in future periods.

Common Stock

In March 2019, the Company issued and sold 2,985,575 shares of common stock in a public offering pursuant to a registration statement and a related prospectus and prospectus supplement. The Company received net proceeds of approximately $1,213.4 million, net of underwriting discounts, commissions and offering expenses.

In August 2017, the Company established an "at-the-market" equity offering program (the "2017 ATM Program") under which the Company may, from time to time, issue and sell shares of its common stock to or through sales agents up to an aggregate of $750.0 million. For the six months ended June 30, 2018, the Company sold 19,100 shares under the 2017 ATM Program, for approximately $7.6 million, net of payment of commissions to the sales agents. As of December 31, 2018, no shares remained available for sale under the 2017 ATM Program. In December 2018, the Company launched another ATM program, under which it may offer and sell from time to time up to an aggregate of $750.0 million of its common stock in "at the market" transactions (the "2018 ATM Program"). For the six months ended June 30, 2019, the Company sold 722,361 shares under the 2018 ATM program, for approximately $348.2 million, net of payment of commissions to sales agents.

Stock-Based Compensation

For the six months ended June 30, 2019, the Compensation Committee and/or the Stock Award Committee of the Company's Board of Directors, as the case may be, approved the issuance of an aggregate of 697,174 shares of restricted stock units to certain employees, including executive officers, pursuant to the 2000 Equity Incentive Plan. These equity awards are subject to vesting provisions and have a weighted-average grant date fair value of $434.17 and a weighted-average requisite service period of 3.66 years. The valuation of restricted stock units with only a service condition or a service and performance condition require no significant assumptions as the fair value for these types of equity awards is based solely on the fair value of the Company's stock price on the date of grant. The Company used revenues and adjusted funds from operations ("AFFO") per share as the performance measurements in the restricted stock units with both service and performance conditions that were granted in the six months ended June 30, 2019.

The Company uses a Monte Carlo simulation option-pricing model to determine the fair value of restricted stock units with a service and market condition. The Company used total shareholder return ("TSR") as the performance measurement in the restricted stock units with a service and market condition that were granted in the six months ended June 30, 2019. There were no significant changes in the assumptions used to determine the fair value of restricted stock units with a service and market condition that were granted in 2019 compared to the prior year.
