Thank you, Ralph, and just a few items from me this morning. Beginning with GAAP and some related metrics, for the first quarter of 2021, net revenues, net income and earnings per share on a GAAP basis were $662 million, $144 million and $3.25 respectively. Our GAAP tax rate for the first quarter was 16.1% compared to 25.8% for the prior year period. The appreciation in the firm's share price upon vesting of employee share based awards above the original grant price positively affected our effective tax rate on both the GAAP and adjusted basis. On a GAAP basis, our share count was $44.5 million shares for the first quarter. The share count for adjusted earnings per share was $49.4 million for the quarter. Focusing for a moment on non-compensation costs, as John noted, we continued to generate significant operating leverage, in part due to lower non-compensation costs. Firm wide non-compensation costs per employee were approximately $40,000 for the first quarter, down 9% on a year-over-year basis. The decrease in non-compensation costs per employee versus last year, primarily reflects lower travel and related expenses. As we continue to evolve towards more normal operations, including returning to our offices and engaging in-person with our clients, costs associated with recruiting, travel, entertainment, and other expenses are expected to increase. I'd like to call your attention briefly to a modest change in presentation that we made in our income statement during the quarter. Commissions and Related Fees, has been renamed to Commissions and Related Revenues, and now includes riskless principal profits, which were previously in other revenue, including interest and investments. The reclassified revenue principally represents the spread income earned from riskless principal transactions in convertibles and other fixed income securities. The reclassification of amounts for this change going back eight quarters can be found in our press release. Finally focusing on the balance sheet two points. On March 29, we issued $38 million of aggregate principal amount of unsecured senior notes with a 1.97% coupon through a private placement. We use the proceeds from the notes to refinance senior notes that matured on March 30. And finally, at the end of the quarter, we held $411 million in cash and cash equivalents and $873 million in Investment Securities, down from year end due to compensation related payments, and a strong return of capital. We'd now like to turn the call over for questions. Operator if you could open the line.
