Table of Contents Liquidity and Capital Strategy September 2021, then $1.1 billion through March 2022, $1.0 billion through August 2022 and approximately $500.0 million thereafter until December 2025. Approximate weighted average fixed interest rates for the aforementioned periods are 2.66%, 2.78%, 2.77%, and 2.64%, respectively. We expect that cash flows from operations and current cash balances, together with available borrowings under our Revolving Facility, will be sufficient to meet operating requirements through the next twelve months. Cash available from operations, however, could be affected by any general economic downturn, such as financial impacts related to COVID-19, or any decline or adverse changes in our business such as a loss of clients, competitive pressures, or other significant change in business environment. In July 2020, our Board cancelled all prior repurchase authorizations and established a new share repurchase authorization of up to $1.0 billion. During the years ended December 31, 2020, 2019, and 2018, we repurchased approximately 6.8 million, 2.0 million, and 2.3 million shares of our common stock for $509.3 million, $86.7 million, and $109.1 million, respectively, including commission costs. As of December 31, 2020, we had $500.0 million in value of shares available to be repurchased under the plan. Pursuant to the Merger Agreement, we agreed to refrain from repurchasing our capital stock during the Interim Operating Period, subject to the terms, limitations and exceptions set forth in the Merger Agreement. See  Item 5 - Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities - Purchases of Equity Securities by the Issuer and Affiliated Purchasers  for further discussion. For the year ended December 31, 2020, we paid cash dividends of $85.7 million. In J uly 2020, our Board announced a 50% increase to the quarterly cash dividend, declaring a cash dividend of $0.33 per share of common stock which was paid in September 2020 and December 2020. Pursua nt to the Merger Agreement, we agreed to refrain from declaring or paying any dividends during the Interim Operating Period, subject to the terms, limitations and exceptions set forth in the Merger Agreement. We strive to pursue a balanced approach to capital allocation and initiated a regular dividend in December 2019. Subject to the limitations during the Interim Operating Period on our ability to (i) make acquisitions or capital expenditures above certain thresholds, (ii) repurchase our capital stock, subject to certain exceptions, (iii) declare or pay dividends, and (iv) incur indebtedness in excess of certain thresholds, in each case pursuant to the Merger Agreement and subject to the terms, limitations and exceptions set forth therein, we will also continue to evaluate management of outstanding debt and pursuits of strategic acquisitions and investments on an opportunistic basis. Our access to additional capital fluctuates as market conditions change. There may be times when the private capital markets and the public debt or equity markets lack sufficient liquidity or when our securities cannot be sold at attractive prices, in which case we would not be able to access capital from these sources. Based on current market conditions and our financial condition (including our ability to satisfy the conditions contained in our debt instruments that are required to be satisfied to permit us to incur additional indebtedness), we believe that we have the ability to effectively access these liquidity sources for new borrowings. However, continued general economic instability, such as financial impacts resulting from COVID- 19 which has caused, and may continue to cause, disruptions in the financial markets or a weakening of our financial condition, including a significant decrease in our profitability or cash flows or a material increase in our leverage, could adversely affect our ability to access these markets and/or increase our cost of borrowings. A summary, by due date, of our total contractual obligations at December 31, 2020, is as follows: (1) Estimated interest payments, net of the effect of our Swaps, are calculated assuming interest rates at December 31, 2020 over minimum maturity periods specified in debt agreements.
