Related Party Transactions [Abstract]
Transactions With Related Parties	17. TRANSACTIONS WITH RELATED PARTIES We are managed by our Manager pursuant to the Management Agreement, the current term of which expires on December 19, 2021, and will be automatically renewed for a one-year term upon such date and each anniversary thereafter unless earlier terminated. As of both March 31, 2021 and December 31, 2020, our consolidated balance sheets included $19.2 million of accrued management and incentive fees payable to our Manager. During the three months ended March 31, 2021, we paid aggregate management and incentive fees of $19.2 million to our Manager, compared to $20.2 million during the same period of 2020. In addition, during the three months ended March 31, 2021, we reimbursed our Manager for expenses incurred on our behalf of $40,000 compared to $218,000 during the same period of 2020. As of March 31, 2021, our Manager held 856,243 shares of unvested restricted class A common stock, which had an aggregate grant date fair value of $27.2 million, and vest in installments over three years from the date of issuance. During the three months ended March 31, 2021 and 2020, we recorded non-cash expenses related to shares held by our Manager of $4.0 million and $4.3 million, respectively. Refer to Note 14 for further details on our restricted class A common stock. An affiliate of our Manager is the special servicer of the CLOs. This affiliate did not earn any special servicing fees related to the CLOs during the three months ended March 31, 2021 or 2020. During the three months ended March 31, 2020, we originated two loans whereby the respective borrowers engaged an affiliate of our Manager to act as title insurance agent in connection with these transactions. We did not incur any expenses or receive any revenues as a result of these transactions. There were no similar transactions during the three months ended March 31, 2021. During the three months ended March 31, 2021 and 2020, we incurred $100,000 and $133,000, respectively, of expenses for various administrative, compliance, and capital market data services to third-party service providers that are affiliates of our Manager. In the first quarter of 2021, we acquired an SEK 5.0 billion interest in a total SEK 10.2 billion senior loan to a borrower that is wholly owned by a Blackstone-advised i nvestment vehicle. We will forgo all non-economic rights under the loan, including voting rights, so long as we are an affiliate of the borrower. The senior loan terms were negotiated by a third party without our involvement and our 49% interest in the senior loan was made on such market terms. In the first quarter of 2021, a Blackstone-advised investment vehicle acquired an aggregate $5.5 million participation, or 3%, of the $200 million increase to our 2019 Term Loan as a part of a broad syndication lead-arranged by JP Morgan. Blackstone Securities Partners L.P., an affiliate of our Manager, was engaged as a book-runner for the transaction and received aggregate fees of $200,000 in such capacity. Both of these transactions were on terms equivalent to those of unaffiliated parties. In the first quarter of 2020, we acquired a $140.0 million interest in a total $421.5 million senior loan to a borrower that is partially owned by a Blackstone-advised investment vehicle. We will forgo all non-economic rights under the loan, including voting rights, so long as we are an affiliate of the borrower. The senior loan terms were negotiated by third parties without our involvement and our 33% interest in the senior loan was made on such market terms.
