Equity [Abstract] |
Stockholders' Equity | STOCKHOLDERS’ EQUITY Stock Repurchase Program On December 13, 2018, Ciena announced that its Board of Directors authorized a program to repurchase up to $500 million of Ciena’s common stock. The program may be modified, suspended, or discontinued at any time. Due to the continued uncertainty surrounding the duration and severity of potential macroeconomic impacts of COVID-19, Ciena considered it prudent to temporarily suspend purchases of its common stock under its stock repurchase program effective as of March 17, 2020. The reinstatement of the program and the amount and timing of repurchases are subject to a variety of factors including liquidity, cash flow, stock price, and general business and market conditions. The following table summarizes activity of the stock repurchase program, reported based on trade date:
| Shares Repurchased |  | Weighted-Average Price per Share |  | Amount Repurchased (in thousands)
Cumulative balance at November 2, 2019 | 3,838,466 |  |  | $ | 39.10 |  |  | $ | 150,076 |
Repurchase of common stock under the stock repurchase program | 1,872,446 |  |  | 39.81 |  |  | 74,535 |
Cumulative balance at August 1, 2020 | 5,710,912 |  |  | $ | 39.33 |  |  | $ | 224,611 |
The purchase price for the shares of Ciena’s stock repurchased is reflected as a reduction of common stock and additional paid-in capital. Stock Repurchases Related to Stock Unit Award Tax Withholdings Ciena repurchases shares of common stock to satisfy employee tax withholding obligations due on vesting of stock unit awards. The purchase price of $26.3 million for the shares of Ciena’s stock repurchased during the first nine months of fiscal 2020 is reflected as a reduction to stockholders’ equity. Ciena is required to allocate the purchase price of the repurchased shares as a reduction of common stock and additional paid-in capital.
