Lloyds Banking Group (NYSE: LYG) has disappointed its investors by reporting a massive first-quarter loss of $3.9 billion. This loss was largely due to a $5.3 billion provision for payment protection insurance (PPI) that the bank had to make to cover payouts.

A court in Britain didn't see merit in the banks' lawsuit challenging mis-selling of insurance policies. Barclays (NYSE: BCS) and Royal Bank of Scotland (NYSE: RBS), the other major players in the PPI business, are expected to go through a similar hammering, and the insurance claims could go beyond $16 billion.

Looking beyond losses
Despite losses, Lloyds saw significant improvements in most of its key areas in the quarter. The bank has been focusing on reducing risky assets; non-core assets were reduced by almost $33 billion. It also strengthened its funding position by a public funding issuance of $21.7 billion. Customer deposits grew by $10.9 billion, while core customer loans and advances increased to $1.36 billion, from $1.35 billion in the preceding quarter, improving its core loan-to-deposit ratio to 116%.

Although its profit before tax declined to $456 million in the quarter, from $1.7 billion in the year-ago quarter, Lloyds would have still remained profitable, had it not been for the PPI provision. Considering that it is a non-recurring expense, investors shouldn't be too nervous about the losses. However, there are several other challenges which should definitely make you fret.

As I mentioned in a prior article, Lloyds is being pressed by the U.K.'s Independent Commission on Banking to sell off further branches to improve competition. This forced divestment may result in the bank's retail segment taking a hit. Besides, fiscal austerity in the U.K. paints a gloomy picture for the banks.

The Foolish bottom line
Lloyds' shares have performed badly in the recent months and fell 8% on the news of its losses. The British bank will have to navigate choppy waters before it can sail smoothly.
