Aug 9 (Reuters) - InvoCare Ltd on Wednesday backed a lower takeover offer from private-equity firm TPG Global, valuing the Australian funeral service provider at A$1.8 billion ($1.18 billion) following exclusive due diligence.

TPG tabled an all-cash offer of A$12.70 per share, below its previous A$13 bid for the Australian company.

InvoCare's board unanimously recommended its shareholders to vote in favour of the revised proposal.

TPG did not immediately respond to a Reuters' request for comment.

The private-equity firm, which holds about a 19.2% stake in InvoCare and is its largest shareholder, had first approached the New South Wales-based company in March with a A$12.65 per share offer.

In May, InvoCare received the A$13 apiece bid from TPG and had agreed to a five-week due diligence on an exclusive basis to deliver a binding offer.
