Exchange-traded fund companies are wearing green as they roll out two new offerings designed to track socially responsible indexes.

Barclay's Global Investors, the leader in ETFs with over $111 billion in ETF assets, formally introduced the iShares KLD Select Social Index Fund ( KLD) Monday. The ETF started trading last Friday under the ticker "KLD" on the New York Stock Exchange.

The expense ratio for the ETF is 50 basis points. Shares of KLD recently traded at $50.36, up 52 cents.

The KLD follows the KLD Select Social Index, which comprises 250 to 350 non-tobacco companies found in the Russell 1000 and ranked according to their social and environmental impact. The rankings are performed by KLD Research & Analytics, a Boston-based investment research and index firm.

In evaluating a company, KLD says it considers the environment, labor relations, community relations, diversity, product safety human rights record and governance.

The Select Social Index was introduced in June 2004 and returned 9.8% in the fourth quarter, matching the Russell 1000, according to KLD. For the month of December 2004, the KLD index gained 3.65%, 3 basis points better than the Russell 1000.

The index's top 10 holdings at Dec. 31 were Wells Fargo ( WFC), Microsoft ( MSFT), Procter & Gamble ( PG), Fannie Mae ( FNM), General Mills ( GIS), Bank of America ( BAC), Johnson & Johnson ( JNJ), General Electric ( GE), St. Paul Travelers ( STA) and Intel ( INTC).

Lee Kranefuss, CEO of BGI's Intermediary Business, says KLD addresses one of the principal barriers facing socially responsible investment: the reluctance of institutional investors to limit diversification across the market.

"This ETF responds to these concerns by investing in domestic companies representing every industry, except tobacco, modifying their weights based on their social characteristics and maintaining risk exposure similar to the Russell 1000," says Kranefuss.

PowerShares Capital Management, BGI's far smaller rival with about $500 million in assets, announced its intentions today to release its own socially responsible ETF.
