ZURICH, Oct 13 (Reuters) - Crisis-ridden Credit Suisse (CSGN.S) is going on the offensive under new Chairman Antonio Horta-Osorio by providing free services for investors in collapsed supply chain finance funds linked to Greensill, a person familiar with the situation told Reuters.

This would cover standard brokerage fees as well as discretionary mandate fees, investment advisory fees and banking services. Fund of funds from other providers, for example, are excluded from the fee waiver. It was not yet clear how long the offer will last or how much it will ultimately cost.The bank"s $10 billion in funds linked to Greensill imploded in March when insurance cover lapsed, pushing the financing group into insolvency. read more Credit Suisse has been working with advisers to help recoup the funds, some $7.0 billion of which had been recovered by the end of September. read more Many clients who were sold the Greensill funds as products with a manageable risk reacted angrily, and some have taken legal action. Analysts have estimated the possible legal costs at $2 billion. "Credit Suisse acknowledges that this has been a difficult period for investors in the Supply Chain Finance funds. We continue to make good progress on recovering cash both from obligors and via insurance claims; however, recovery from the focus areas will take time to achieve," the bank said. "We have therefore also been actively engaging with our clients in recent months to explore possible measures that would improve their situation. We have taken their feedback on board, explored the viability of a number of scenarios and, starting with clients in Switzerland, we are now able to grant special conditions as a gesture of our commitment to these important relationships," it added in a statement. "FREE OPTION" The bank is launching the fee waiver programme on Wednesday for clients whose accounts are booked in Switzerland, the source said. The offer will then be broadened out to other regions. The programme will cover the Switzerland, Asia-Pacific and International Wealth Management divisions for now. Management fees on the Greensill funds themselves have already been waived since March. Clients participating in the programme would not have to forego legal action, but would have to agree that any gain from legal action will be reduced by the amount of the reimbursement received. "Essentially, this is a free option," the source said. Customers who had already initiated legal proceedings were excluded from the programme.
