NEW YORK (Standard&Poor's) June 9, 2015--Standard&Poor's Ratings Services assigned 18 various ratings to nine different Mesirow Municipal Funding tender-option bond series 2015-XM trust puttable floater receipts and inverse floating-rate residual receipts. (Please see the table below.) These trusts are issued under the common document initiative using net liquidity. For these transactions, Mesirow Financial Inc. is both the trustor and trust administrator. Morgan Stanley Bank N.A. is the liquidity provider. The receipts were formerly issued under individual trusts by Morgan Stanley&Co. LLC Trust. The CUSIPs associated with the former floater and residual certificates will remain the same. Mesirow Financial Inc., however, will transfer the underlying bonds to the new individual trusts and issue new receipts.
