Massachusetts Commonwealth Transportation Fund Ratings Unchanged By Addition Of Series 2016B And Par Increase NEW YORK - S&P Global Ratings today said its ratings on the Commonwealth of Massachusetts commonwealth transportation fund (CTF) revenue bonds (AAA/Stable) are unchanged based on the commonwealth's decision to issue its series 2016 CTF revenue bonds as two separate series  (2016A and 2016B) and increasing the total par amount by approximately $10 million.  On Sept. 16, 2016, we assigned our 'AAA' rating with a stable outlook, to Massachusetts' $325.965 million CTF revenue bonds (rail enhancement and  accelerated bridge program, series 2016A). However, at pricing, the  commonwealth decided to split the bonds into series 2016A, which priced Sept.  29 and had a par amount of $136.565 million; and series 2016B with an  estimated par amount of $200 million, which is expected to price mid-November.  In our view, although the total par amount increased by approximately $10  million, the all-in maximum annual debt service coverage is unchanged from our prior report.   For more information on the series 2016A and 2016B revenue bonds, see our report published Sept. 16, 2016, on RatingsDirect. Only a rating committee may determine a rating action and this report does not constitute a rating action.
