The debt office said it would sell 25 billion naira each in the 5-, 7- and 10-year paper with term-to-maturity of four years and eight months, six years and 10 months, and nine years and five months respectively.  The bonds are re-openings of previous issues.

"The DMO reserves the right to alter the amount allotted in response to market conditions," the debt office said in a statement sent to Reuters by email.

Nigeria, Africa's second-biggest economy after South Africa, issues sovereign bonds monthly to support the local bond market, create a benchmark for corporate issuance and fund its budget deficit.
