Dexus Property Group (rated BBB+) became the third issuer in recent months to take advantage of improved conditions in the corporate bond market and increasing investor appetite for longer-term exposures. Stockland (rated A-) was the first to do this in December 2009, when it bought back A$175 million of outstanding June 2011 bonds and issued A$300 million of February 2015 bonds. The week before last, Adelaide Airport (BBB) bought back 85 per cent of its credit wrapped, December 2010 bonds (A$204 million) and issued A$235 million of September 2015 bonds, in its own right. Dexus last week bought back A$178.9 million of February 2011 bonds at par and issued A$180 million of seven-year bonds. The new bonds were priced at 270 basis points over swap, to yield 8.78 per cent per annum.Westpac also took the opportunity to get some more, longer-term, debt in place, adding another A$110 million to its February 2020 line. Priced at 145 bps over swap, the top-up takes total outstandings to A$350 million.   The World Bank (through its arm, the International Bank for Reconstruction and Development) has become a more frequent issuer since returning to the Australian domestic bond market in October 2009 after an absence of three years.IBRD issued A$1.5 billion of five-year bonds in February and last week it added A$900 million to its October 2019 line and A$500 million to its November 2016 line. The additions were priced at 21 bps and 19 bps over swap and 59 bps and 46 bps over CGS and take outstandings to A$1.5 billion and A$1.0 billion, respectively.European Investment Bank added A$650 million to its January 2017 line, at a spread of 32 bps over swap to yield 6.365 per cent per annum. The increase was reported as taking outstandings to A$1.6 billion but our data show that there was already that amount outstanding and the increase would actually be to A$2.25 billion.Council of Europe Development Bank also topped up its December 2015 line by A$300 million, taking outstandings to A$1.3 billion. The top-up was priced at 70.5 bps over CGS to yield 6.24 per cent per annum.  More investor briefings were held last week, with Airservices Australia and LeasePlan doing the rounds.Offshore, CBA is lining up in the Uridashi market.
