In February 2019, a Wilson Sonsini pro bono team represented The Nature Conservancy in its issuance of $40 million aggregate principal amount of 4.496 percent Taxable Bonds, Series 2019A, and $62 million aggregate principal amount of Floating Rate Taxable Bonds, Series 2019B, in an underwritten offering. J.P. Morgan and BofA Merrill Lynch were the underwriters for the offering. The net proceeds of the offering will be used to redeem The Nature Conservancy's outstanding 6.30 percent Bonds due July 1, 2019. The Nature Conservancy was established in 1951, and its mission is to conserve the lands and waters on which all life depends.

Wilson Sonsini's team included partners Michael Occhiolini, Michael Labriola, and Charlotte Kim, and associates Michael Rosati, Stephen Horton, Elisa Sielski, Meghan Thomsen, and Alan Campbell.
