outstanding principal balance of any borrowings under our credit facility, plus (ii) our accounts payable owing to artists selling works on our platforms (Society6 and Saatchi Art). We are required to maintain a Liquidity Ratio of at least 1.50 to 1.00. The First Amendment also provides for incremental borrowing flexibility for six months, with aggregate borrowing still capped at $10.0 million.
As of March 31, 2021, we had $4.0 million of borrowings outstanding under our credit facility at an interest rate of 5.25%. Our total borrowing capacity under the credit facility was $7.5 million as of March 31, 2021. We are in compliance with all restrictions and have met all debt payment obligations as of March 31, 2021.
On May 5, 2021, we repaid all amounts due and owed under the credit facility with Silicon Valley Bank for the principal, interest, and other amounts owed in the amount of $4.0 million. Effective immediately upon such repayment, (i) all obligations under the credit facility were paid and discharged in full; (ii) all unfunded commitments to make credit extensions or financial accommodations to us or any other person thereunder were terminated; (iii) all security interests and other liens granted to or held by the Lender were terminated and released; and (iv) all guaranties supporting the credit facility were released without further action from the Lender; provided that certain letter of credit and bank services obligations previously secured together with the credit facility survive such termination and are now separately cash collateralized.
Paycheck Protection Program Loan. On April 20, 2020, we entered into the Promissory Note with Silicon Valley Bank and Silicon Valley Bank agreed to make available to us the PPP Loan in the amount of $7.1 million under the SBA Paycheck Protection Program enabled by the CARES Act. We used the proceeds to support payroll costs, rent and utilities in accordance with the relevant terms and conditions of the CARES Act. The advance under the PPP Loan bears interest at a rate per annum of 1.0%. The term of the PPP Loan is two years, ending April 20, 2022 (the “Maturity Date”). No payments are due on the PPP Loan until September 20, 2021, although interest will accrue during the deferment period. Beginning September 20, 2021, we will pay equal monthly installments of principal and interest in the amount necessary to fully amortize the PPP Loan through the Maturity Date, less any amount of potential forgiveness. Under the terms of the CARES Act, all or a portion of the principal of the PPP Loan may be forgiven. Such forgiveness will be determined, subject to limitations, based on the use of the PPP Loan proceeds for payroll costs, mortgage interest payments, lease payments or utility payments. On November 30, 2020, we filed an application seeking forgiveness of the PPP Loan. On January 27, 2021, we received notification from Silicon Valley Bank that our loan forgiveness application has been submitted to the SBA. While we believe we used the PPP Loan proceeds in a manner that would permit forgiveness of the PPP Loan, no assurance can be provided that we will obtain forgiveness of the PPP Loan in whole or in part. We may also prepay the principal of the PPP Loan at any time without incurring any prepayment penalty or premium. The Promissory Note also provides for customary events of default, including, among others, events of default relating to failure to make payments, bankruptcy, breaches of representations, and material adverse effects. Additionally, the Promissory Note is subject to the terms and conditions applicable to loans administered by the SBA under the CARES Act. We did not provide any collateral or personal guarantees for the PPP Loan, nor did we pay any facility charge to the government or to Silicon Valley Bank. Additionally, Silicon Valley Bank consented to the PPP Loan as additional permitted indebtedness under our existing revolving credit facility.
Asset Sale to Hearst Newspapers. On April 24, 2020, we entered into an Asset Sale and Services Agreement (the “Agreement”) with Hearst Newspapers, a division of Hearst Communications, Inc. (“Hearst”), pursuant to which we sold a library of content carried on certain websites (the “Hearst Sites”) that had been hosted by us on behalf of Hearst (the “Hearst Content”) to Hearst for $9.5 million, of which $4.0 million was paid at signing. The balance of $5.5 million was paid on August 21, 2020, upon completion of the migration of the Hearst Content to servers controlled by Hearst. In addition, the Agreement contemplates that, for a three-year initial term, we will provide certain content and web services in connection with the management of the Hearst Content, for which we will be paid certain fees for the content and web services provided and a revenue share based on the net revenue from the Hearst Sites.
We anticipate that existing cash and cash equivalents, and forecasted operating cash flows will be sufficient to fund our operations for at least the next 12 months. However, in order to fund our operations, make potential acquisitions, pursue new business opportunities and invest in our existing businesses, platforms and technologies, we may need to raise additional funds by entering into an additional loan or credit facility, selling certain assets or issuing equity, equity-related or debt securities.
Since our inception, we have used cash and stock to make strategic acquisitions to grow our business. We have also generated cash by disposing of certain businesses. We may make further acquisitions and dispositions in the future.
Under our stock repurchase plan announced in August 2011 and amended in February 2012, we are authorized to repurchase up to $50.0 million of our common stock from time to time in open market purchases or negotiated transactions. During the year ended December 31, 2016, we repurchased $4.9 million of our common stock. We have not initiated any repurchases of our common stock since
