You are a financial expert. After reading the following paragraph, give me the new amount of the loan and date it was amended in the format "Amount,Date", where "Date" is in the format "YYYY-MM-DD". As an example, "$200|1901-09-01".

"On June 8, 2018, the Company entered into a fourth amendment of an April 7, 2015 term loan agreement by and between the Company and Bank of America, N.A. (the “Term Loan Agreement”) under which Term Loan Agreement the Company borrowed a principal amount of $500 million. This amendment increases the principal amount borrowed by the Company under the Term Loan Agreement to $750 million.  Except as modified by the fourth amendment, the terms of the Term Loan Agreement remain the same. Proceeds from the borrowings were used, in part, to fund an acquisition, and for other general corporate purposes. The foregoing description of the fourth amendment to the Term Loan Agreement is summary in nature and is qualified in its entirety by reference to this amendment, a copy of which is attached hereto as Exhibit 10.1, and incorporated herein by reference."
