​ In July 2020, the Company’s board of directors approved a two-for-one stock split in the form of a stock dividend, payable on August 18, 2020, to stockholders of record as of the close of business on August 14, 2020. The Company’s stockholders received one additional share of common stock for each share of common stock held on August 14, 2020. The share and per share information for all periods presented in this Form 10-Q reflects the effect of the stock split. Common Stock Repurchases The Company did not repurchase any common stock during the three months ended March 31, 2021. As of March 31, 2021, the Company had approximately $41.3 million remaining under its current repurchase program, which has no expiration date. In April 2021, the Company’s board of directors authorized the use of an additional $50.0 million for the repurchase of the Company’s common stock, with repurchases to be executed according to pre-defined price/volume guidelines. Authorization of future repurchase programs is at the discretion of the board of directors and will depend on the Company’s financial condition, results of operations, capital requirements, business conditions and other factors. Cash Dividends In October 2019, the Company’s board of directors declared four quarterly cash dividends of $0.095 per share to be paid to stockholders of record at the end of each quarter in 2020. In April 2020, the Company’s board of directors raised the cash dividends with the declaration of three cash dividends of $0.105 per share (in lieu of the $0.095 per share previously announced in October 2019) to be paid to stockholders of record at the end of each of the second, third and fourth quarter in 2020. In July 2020, the Company’s board of directors raised the cash dividends further with the declaration of two cash dividends of $0.11 per share (in lieu of the $0.105 per share announced in April 2020) to be paid to stockholders of record at the end of each of the third and fourth quarter in 2020. In January 2021, the Company’s board of directors raised the quarterly cash dividend by an additional $0.02 per share with the declaration of four cash dividends of $0.13 per share to be paid to stockholders of record at the end of each quarter in 2021. For the three months ended March 31, 2021, and 2020, cash dividends declared and paid were as follows:
