MetWest Intermediate Bond Fund
Summary Prospectus

Shareholder Fees (fees paid directly from your investment):
None

Annual Fund Operating Expenses
(Expenses that you pay each year as a percentage of the value of your investment)

Management Fees	0.35%
Distribution (12b-1) Fees	None
Other Expenses	0.16%
Acquired Fund Fees and Expenses	0.01%
Total Annual Fund Operating Expenses (1)	0.52%
Fee Waiver and/or Expense Reimbursement (2)	0.07%
Total Annual Fund Operating Expenses after Fee Waiver and/or Expense Reimbursement (2)	0.45%

(1) Total Annual Fund Operating Expenses will not correlate to the ratio of Expenses to Average Net Assets found in the “Financial Highlights” section of the Prospectus, which reflects the operating expenses of the Fund, but does not include Acquired Fund Fees and Expenses.

(2) Metropolitan West Asset Management, LLC (the "Adviser") has contractually agreed to waive advisory fees and/or reimburse expenses, including distribution expenses, to limit the Fund's total annual operating expenses (excluding interest, taxes, brokerage commissions, short sale dividend expenses, AFFE, and any expenses incurred in connection with any merger or reorganization or extraordinary expenses such as litigation) to 0.44% of average daily net assets. This contract will remain in place until July 31, 2012. Although it does not expect to do so, the Board of Trustees is permitted to terminate the contract sooner in its discretion with written notice to the Adviser. The Fund incurred AFFE for the year ended March 31, 2011. If AFFE had not been incurred, the ratio of annualized operating expenses to average net assets for the year ended March 31, 2011 would have been 0.44%.

EXAMPLE
This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$46	$160	$284	$646

PORTFOLIO TURNOVER
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 192% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
The Fund pursues its objective by investing, under normal circumstances, at least 90% of its net assets in fixed-income securities rated investment grade or unrated securities that are determined to be of similar quality. Up to 10% of the Fund’s net assets may be invested in securities rated below investment grade. The Fund also invests at least 80% of its net assets plus borrowings for investment purposes in fixed income securities it regards as bonds. Under normal conditions, the portfolio duration is one to six years and the dollar weighted average maturity ranges from three to seven years. The Fund invests in the U.S. and abroad, including emerging markets and may purchase securities of varying maturities issued by domestic and foreign corporations and governments.

Investments include various types of bonds and other securities, typically corporate bonds, notes, collateralized bond obligations, collateralized debt obligations, mortgage-related and asset-backed securities, bank loans, money-market securities, swaps, futures, municipal securities, options, credit default swaps, private placements and restricted securities. These investments may have interest rates that are fixed, variable or floating.

Derivatives will be used in an effort to hedge investments, for risk management, or to increase income or gains for the Fund. The Fund may also seek to obtain market exposure to the securities in which it invests by entering into a series of purchase and sale contracts or by using other investment techniques such as reverse repurchase agreements.

PRINCIPAL RISKS
Because the Fund holds securities with fluctuating market prices, the value of the Fund’s shares will vary as its portfolio securities increase or decrease in value. Therefore, the value of your investment in the Fund could go down as well as up. You can lose money by investing in the Fund.

The principal risks affecting the Fund that can cause a decline in value are:

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. In some cases, returns after taxes on distributions and sale of Fund shares may be higher than returns before taxes because the calculations assume that the investor received a tax deduction for any loss incurred on the sale of the shares.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

Shareholders who purchase or hold shares through an intermediary may inquire about such payments from that intermediary.
