Tax-free municipal bonds produced solid gains and outperformed taxable investment-grade bonds in the six-month period ended August 31, 2017. The Bloomberg Barclays Municipal Bond Index returned 3.79% versus 2.74% for the Bloomberg Barclays U.S. Aggregate Bond Index. Muni bonds were supported by steady demand and limited new issuance for most of the period. Longer-term municipals outperformed shorter maturities as the yield curve flattened, and lower-rated bonds outpaced higher-quality securities as investors continued to seek out higher yields. California debt generally performed in line with the broad national muni index. The California Tax-Free Bond Fund outperformed its benchmark but trailed its peer group average in the six-month period, while the California Tax-Free Money Fund performed roughly in line with its peers.

The U.S. economy grew at a strong 3.0% annualized rate in the second quarter of 2017, according to the Commerce Department’s most recent estimate—a pickup from the 1.2% growth rate in the first quarter. The labor market has been healthy, with the national unemployment rate falling to 4.4% in August. Inflation data were very weak in the early months of our reporting period, but pricing pressures more recently have shown signs of normalizing.

While Hurricane Harvey is having a significant impact on the highly populated and energy-dependent region around Houston, Texas, we believe the national economic effects of the storm will be short-lived. With specific regard to the municipal bond market, we believe that while Harvey may add some operating costs to impacted issuers over the short term, between insurance, federal aid, and state support, local governments will receive enough aid that should allow them to recover without any significant long-term effects.

The Federal Reserve raised short-term interest rates in March and in June, lifting the fed funds target rate to the 1.00% to 1.25% range. The Fed has now raised rates four times since late 2015, and central bank officials expect to raise rates once more in 2017. The Fed is also poised to begin unwinding its $4.5 trillion balance sheet, a legacy of its massive purchases of Treasury bonds and mortgage-backed securities in the aftermath of the 2008 financial crisis.

Both the Treasury and municipal yield curves flattened in the first half of our fiscal year, with short-term municipal yields moving incrementally higher, while short-term Treasury rates increased to a greater degree, as they were more sensitive to the Fed’s rate hikes. Intermediate- and long-term yields decreased, with the move lower being more pronounced in the muni market. At the end of August, high-quality 30-year muni yields were slightly lower than the 30-year U.S. government bond yield. Nonetheless, municipals still offer relative value for many fixed income investors on an after-tax basis.

As an illustration of their relative attractiveness, on August 31, 2017, the 2.70% yield offered by a 30-year tax-free general obligation (GO) bond rated AAA was about 99% of the 2.73% pretax yield offered by a 30-year Treasury bond. Including the 3.8% net investment income tax that took effect in 2013 as part of the Affordable Care Act, the top marginal federal tax rate currently stands at 43.4%. An investor in this tax bracket would need to invest in a taxable bond yielding 4.77% to receive the same after-tax income as that generated by the municipal bond. (To calculate a municipal bond’s taxable-equivalent yield, divide the yield by the quantity of 1.00 minus your federal tax bracket expressed as a decimal—in this case, 1.00 – 0.434, or 0.566.)

Total year-to-date municipal bond issuance through the end of August was about $256 billion, according to The Bond Buyer, which was 15% lower than the same period in 2016. A sharp drop in refunding issuance drove the decline in supply. Fund flows have been mostly positive during the last six months, which, combined with lower supply, created a strong technical backdrop for muni bonds. Generally, fundamentals for municipal issuers remain solid, and most issuers in the $3.8 trillion municipal bond market have been fiscally responsible. State and local governments in general have been cautious about adding to indebtedness since the 2008 financial crisis, and a strengthening economy has helped tax revenues rebound. Over 60% of the market, as measured by the Bloomberg Barclays Municipal Bond Index, is AAA or AA rated.

Although the market is overwhelmingly high quality, many states and municipalities are grappling with underfunded pensions and other post-employment benefit (OPEB) obligations. New reporting rules from the Governmental Accounting Standards Board are bringing greater transparency to state and local governments’ pension funding gaps, long-term risks that investors often overlooked in the past. We believe the market will increasingly price in higher pension risks as the magnitude of unfunded liabilities becomes more conspicuous.

In credit news, the deteriorating fiscal situation in Illinois drew increased scrutiny as political dysfunction led to yet another budget impasse. Moody’s Investors Service and S&P Global Ratings downgraded Illinois’ general obligation debt to the lowest investment-grade level after the state’s regular legislative session ended on May 31 without a budget. The Democrat-controlled state legislature returned for a special session at the end of June and finally passed a budget despite the objections of Governor Bruce Rauner, a Republican, who had vetoed the deal because of its significant tax increases and lack of long-term reforms.

In May, Puerto Rico’s financial oversight board filed petitions with the U.S. District Court seeking help in restructuring approximately $51 billion in debt issued directly by the island’s central government as well as the commonwealth’s COFINA debt, which is backed by sales tax revenue. In early July, PREPA, the commonwealth’s electric utility, filed for bankruptcy after the oversight board rejected the restructuring agreement that had been reached between the power authority and its creditors. The court filings could lead to the largest restructuring of municipal debt in U.S. history. While credit-challenged muni issuers such as Illinois and Puerto Rico made headlines during our reporting period, the negative news seemed to have little impact on the broader tax-exempt bond market.

Sector performance across the muni market was broadly positive, as revenue bonds narrowly outperformed general obligation debt. We continue to favor bonds backed by a dedicated revenue stream over GOs, as we consider revenue bonds to be largely insulated from the pension funding concerns facing state and local governments. Among investment-grade revenue bonds, all subsectors produced positive returns, with hospital and leasing revenue bonds performing well, while resource recovery bonds lagged. High yield tobacco debt gained more than 7% and was the strongest-performing sector in the muni market.

The California economy continued to exhibit modest growth in the first half of 2017. Nonfarm payrolls increased 1.7% for the 12 months ended July 2017; the state’s unemployment rate was 4.8%, down from 5.4% a year ago but still higher than the national average. In another sign of economic growth, the median price of single-family homes increased to $549,460 in July 2017, 7.4% higher compared with the same period in 2016. Additionally, year-over-year sales increased 0.9%, according to the California Association of Realtors.

California’s fiscal position has improved in recent years, though the rate of growth will likely slow. General fund revenues rose 0.7% in fiscal year 2016 to $117.6 billion, while expenditures jumped 11.2% to $111.8 billion. Early unaudited figures indicate that the state’s general fund received $125.5 billion for fiscal year 2017, which ended June 30, 2017. California released a balanced budget for fiscal year 2018, which is based on estimates of $127.5 billion in general fund resources and $125.1 billion in expenditures, yielding a general fund balance of $2.4 billion.

California had $83.6 billion of general fund-supported debt outstanding as of August 1, 2017. General obligation bonds totaled $74.2 billion while lease revenue bonds represented $9.4 billion. Moody’s Investors Service rates the Golden State’s GO bonds Aa3, while S&P and Fitch rate the bonds AA-. All three ratings agencies have stable outlooks on California. Lease-revenue bonds are typically rated one or two notches below GO bonds.

California Tax-Free Money Fund
Your fund returned 0.13% in the six-month period ended August 31, 2017, while its peer group, represented by the Lipper California Tax-Exempt Money Market Funds Index, returned 0.16%.

After the Fed’s two interest rate hikes this year, the overall level of short-term municipal rates has moved higher. But the impact on the municipal money market from these rate increases has been somewhat muted due in part to the continued uncertainty about the frequency and timing of future rate increases, as well as by the continued interest of nontraditional buyers of short-term municipal paper. As interest rates move higher, variable rate demand notes (VRDNs), in particular, have remained attractive to nontraditional investors, including taxable money funds, due to yields that are comparable to taxable securities and other liquidity attributes, though this effect seemed to be fading as the period ended.

Demand for tax-exempt paper from higher-tax states such as California has pressured rates more than the national average. Since our last report, overnight California yields have averaged about 0.55%, while seven-day California yields have averaged about 0.77%. On the longer end of the money market yield curve, separately managed accounts seeking cash alternatives have been active buyers of bonds with maturities of six to 12 months. While yields on one-year maturities have generally moved higher, yields on longer California paper have actually moved lower to around 0.76%, as the increased demand from these nontraditional buyers has held down yields. This may also be explained in part by tax relationships reasserting themselves after a long period of near-zero rates; investors are again seeing the value of tax-exempt income as short rates move higher.

We have focused on building positions in the front end of the money market yield curve, avoiding what we deem to be overly rich levels in longer maturities. The fund’s commercial paper exposure is higher than it was at the end of February, while bond and note positions are lower. We believe that as the market and its technical influences adjust, a steeper yield curve will offer a better entry point into longer positions.

As always, credit quality plays a significant part in asset selection for the California Tax-Free Money Fund. Currently, we have higher exposures in hospital, utility, and education credits. Some prominent positions in the portfolio include Kaiser Permanente, Los Angeles Department of Water and Power, and the University of California. (Please refer to the fund’s portfolio of investments for a complete list of holdings and the amount each represents in the portfolio.)

Looking ahead, there are reasons to think that further increases in short-term yields may come at a slower pace than previously expected. Early optimism around the possibilities of the administration bringing about fiscal stimulus through infrastructure spending and tax reform at both the corporate and individual levels has faded as the year has progressed. And with it, expectations that the Fed would systematically move short-term rates higher have also faded. Inflation remains subdued, and the recent hurricanes suggest at least some distortions in the upcoming economic data. Although the Fed will soon begin shrinking its balance sheet, the reasons to delay the next short-term rate increase continue to accumulate.

As always, we remain committed to managing a highly liquid, diversified portfolio focused on liquidity and stability of principal, which we deem of utmost importance to our valued shareholders.

California Tax-Free Bond Fund
The California Tax-Free Bond Fund returned 3.91% for the six-month period ended August 31, 2017, underperforming the Lipper California Municipal Debt Funds Average, which returned 4.09% for the same period. However, the fund outperformed the nationally diversified Bloomberg Barclays Municipal Bond Index, which posted a return of 3.79%.

The fund’s duration was little changed during the six-month period, while the weighted average maturity moved longer. Our average duration was modestly longer than the benchmark’s during the period, which aided relative results as yields moved lower across the yield curve. However, we had a slightly shorter duration than our peer group, which was a headwind versus the Lipper average.

In terms of yield curve positioning, we maintained an overweight to bonds with maturities of 15 years and longer relative to the benchmark and an underweight to bonds maturing in three to 10 years. This positioning aided the portfolio as the yields of longer-maturity bonds fell more than the yields of shorter maturities.

Our preference for revenue bonds over GOs remained intact as a result of our longer-term concern that many municipalities will face fiscal challenges related to unfunded pension and OPEB liabilities. Nevertheless, we remain comfortable with the State of California as the largest guarantor in the fund, reflecting its solid fiscal management and the state’s resilient economy.

Within the revenue sector, we added to health care, which remained our largest allocation and largest overweight relative to the benchmark. Concerns about the negative impact that the potential repeal and replacement of the Affordable Care Act could have on the sector diminished during the period as attempts to repeal the law have thus far been unsuccessful. We maintain a positive view on the sector and believe our research capabilities will continue to help us find attractive investments in the health care area. Our purchases in the sector included bonds from Front Porch Communities, a continuing care retirement community, and Kaiser Permanente. (Please refer to the fund’s portfolio of investments for a complete list of holdings and the amount each represents in the portfolio.)

Transportation continues to represent the fund’s second-largest absolute sector weighting. While we are underweight the sector relative to the national benchmark, we are overweight relative to peers. We purchased San Jose Airport bonds during the period, and we added to our exposure in the special tax sector, buying Irvine CA Community Facility District securities. Our underweight in tobacco bonds detracted from our performance relative to our peers as these securities recorded strong results during the period.

We finished the period with a modest overweight to prerefunded bonds, although our allocation to the sector ticked down over the six-month period as refinancing activity slowed from the elevated levels of 2016. Prerefunded bonds provide the fund with another source of liquidity in addition to cash, which we believe is appropriate within the current rate environment, and leaves us well positioned to take advantage of the possibility of further interest rate increases.

With regard to the fund’s credit quality, we reduced our position in AAA rated bonds and added to A rated securities. We continue to overweight A and BBB rated debt as we believe this is an area where our credit research team can find investment opportunities that offer incremental risk-adjusted yield. We maintained a modest exposure to below investment-grade and unrated bonds.

We believe that the municipal bond market remains a high-quality market that offers good opportunities for long-term investors seeking tax-free income. While the uncertainties surrounding tax reform and the increased chance of rising yields represent near-term headwinds for broad muni market performance, in our view fundamentals are sound overall, and global economic uncertainties could spur demand for the asset class. As the Fed continues on the path to interest rate normalization, muni bond yields are likely to rise along with Treasury yields—although probably not to the same extent. While higher yields pressure bond prices, munis should be less susceptible than Treasuries to slowly rising rates given their attractive tax-equivalent yields and the steady demand for tax-exempt income. We expect any potential Fed rate increases to be gradual and modest and believe we could remain in a relatively low rate environment for some time.

While we believe that many states deserve high credit ratings and will be able to continue servicing their debts, we have longer-term concerns about significant funding shortfalls for pensions and OPEB obligations in some jurisdictions. These funding gaps stem from investment losses during the 2008 financial crisis, insufficient plan contributions over time, and unrealistic return assumptions. Although few large plans are at risk of insolvency in the near term, the magnitude of unfunded liabilities is becoming more conspicuous in a few states.

Ultimately, we believe independent credit research is our greatest strength and will remain an asset for our investors as we navigate the current market environment. As always, we focus on finding attractively valued bonds issued by municipalities with good long-term fundamentals—an investment strategy that we believe will continue to serve our investors well.

You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.

Bonds are subject to interest rate risk (the decline in bond prices that usually accompanies a rise in interest rates) and credit risk (the chance that any fund holding could have its credit rating downgraded or that a bond issuer will default by failing to make timely payments of interest or principal), potentially reducing the fund’s income level and share price. The fund is less diversified than one investing nationally. Some income may be subject to state and local taxes and the federal alternative minimum tax.

Bloomberg Barclays Municipal Bond Index: A broadly diversified index of tax-exempt bonds.

Bloomberg Barclays U.S. Aggregate Bond Index: An unmanaged index that tracks domestic investment-grade bonds, including corporate, government, and mortgage-backed securities.

Duration: A measure of a bond fund’s sensitivity to changes in interest rates. For example, a fund with a duration of five years would fall about 5% in price in response to a one-percentage-point rise in interest rates, and vice versa.

Federal funds rate (or target rate): The interest rate charged on overnight loans of reserves by one financial institution to another in the United States. The Federal Reserve sets a target federal funds rate to affect the direction of interest rates.

General obligation (GO) debt: A government’s strongest pledge that obligates its full faith and credit, including, if necessary, its ability to raise taxes.

Lipper averages: The averages of available mutual fund performance returns for specified time periods in categories defined by Lipper Inc.

Other post-employment benefits (OPEB): Benefits paid to an employee after retirement, such as premiums for life and health insurance.

Prerefunded bond: A bond that originally may have been issued as a general obligation or revenue bond but that is now secured by an escrow fund consisting entirely of direct U.S. government obligations that are sufficient for paying the bondholders.

Revenue (or revenue-backed) bond: A bond issued to fund specific projects, such as airports, bridges, hospitals, or toll roads, where a portion of the revenue generated is used to service the interest payments on the bonds.

SEC yield (30-day): A method of calculating a fund’s yield that assumes all portfolio securities are held until maturity. Yield will vary and is not guaranteed.

Weighted average maturity: A measure of a fund’s interest rate sensitivity. In general, the longer the average maturity, the greater the fund’s sensitivity to interest rate changes. The weighted average maturity may take into account the interest rate readjustment dates for certain securities. Money funds must maintain a weighted average maturity of less than 60 days.

Yield curve: A graph depicting the relationship between yields and maturity dates for a set of similar securities. A security with a longer maturity usually has a higher yield. If a short-term security offers a higher yield, then the curve is said to be “inverted.” If short- and long-term bonds are offering equivalent yields, then the curve is said to be “flat.”

This chart shows the value of a hypothetical $10,000 investment in the fund over the past 10 fiscal year periods or since inception (for funds lacking 10-year records). The result is compared with benchmarks, which may include a broad-based market index and a peer group average or index. Market indexes do not include expenses, which are deducted from fund returns as well as mutual fund averages and indexes.

As a mutual fund shareholder, you may incur two types of costs: (1) transaction costs, such as redemption fees or sales loads, and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other fund expenses. The following example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the most recent six-month period and held for the entire period.

Please note that the fund has two share classes: The original share class (Investor Class) charges no distribution and service (12b-1) fee, and the I Class shares are also available to institutionally oriented clients and impose no 12b-1 or administrative fee payment. Each share class is presented separately in the table.

Actual Expenses
The first line of the following table (Actual) provides information about actual account values and expenses based on the fund’s actual returns. You may use the information on this line, together with your account balance, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number on the first line under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes
The information on the second line of the table (Hypothetical) is based on hypothetical account values and expenses derived from the fund’s actual expense ratio and an assumed 5% per year rate of return before expenses (not the fund’s actual return). You may compare the ongoing costs of investing in the fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Note: T. Rowe Price charges an annual account service fee of $20, generally for accounts with less than $10,000. The fee is waived for any investor whose T. Rowe Price mutual fund accounts total $50,000 or more; accounts electing to receive electronic delivery of account statements, transaction confirmations, prospectuses, and shareholder reports; or accounts of an investor who is a T. Rowe Price Personal Services or Enhanced Personal Services client (enrollment in these programs generally requires T. Rowe Price assets of at least $250,000). This fee is not included in the accompanying table. If you are subject to the fee, keep it in mind when you are estimating the ongoing expenses of investing in the fund and when comparing the expenses of this fund with other funds.

You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs, such as redemption fees or sales loads. Therefore, the second line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. To the extent a fund charges transaction costs, however, the total cost of owning that fund is higher.

T. Rowe Price California Tax-Free Income Trust (the trust) is registered under the Investment Company Act of 1940 (the 1940 Act). The California Tax-Free Bond Fund (the fund) is a diversified, open-end management investment company established by the trust. The fund seeks to provide, consistent with prudent portfolio management, the highest level of income exempt from federal and California state income taxes by investing primarily in investment-grade California municipal bonds. The fund has two classes of shares: the California Tax-Free Bond Fund (Investor Class) and the California Tax-Free Bond Fund–I Class (I Class). I Class shares generally are available only to investors meeting a $1,000,000 minimum investment or certain other criteria. Each class has exclusive voting rights on matters related solely to that class; separate voting rights on matters that relate to both classes; and, in all other respects, the same rights and obligations as the other class.

Basis of Preparation The fund is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 (ASC 946). The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), including, but not limited to, ASC 946. GAAP requires the use of estimates made by management. Management believes that estimates and valuations are appropriate; however, actual results may differ from those estimates, and the valuations reflected in the accompanying financial statements may differ from the value ultimately realized upon sale or maturity.

Investment Transactions, Investment Income, and Distributions Income and expenses are recorded on the accrual basis. Premiums and discounts on debt securities are amortized for financial reporting purposes. Income tax-related interest and penalties, if incurred, would be recorded as income tax expense. Investment transactions are accounted for on the trade date. Realized gains and losses are reported on the identified cost basis. Income distributions are declared by each class daily and paid monthly. Distributions to shareholders are recorded on the ex-dividend date. A capital gain distribution may also be declared and paid by the fund annually.

Class Accounting Shareholder servicing, prospectus, and shareholder report expenses incurred by each class are charged directly to the class to which they relate. Expenses common to both classes and investment income are allocated to the classes based upon the relative daily net assets of each class’s settled shares; realized and unrealized gains and losses are allocated based upon the relative daily net assets of each class’s outstanding shares.

New Accounting Guidance In March 2017, the FASB issued amended guidance to shorten the amortization period for certain callable debt securities, held at a premium. The guidance is effective for fiscal years and interim periods beginning after December 15, 2018. Adoption will have no effect on the fund’s net assets or results of operations.

On August 1, 2017, the fund implemented amendments to Regulation S-X, issued by the Securities and Exchange Commission, which require standardized, enhanced disclosures, particularly related to derivatives, in investment company financial statements. Adoption had no effect on the fund’s net assets or results of operations.

The fund’s financial instruments are valued and each class’s net asset value (NAV) per share is computed at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day the NYSE is open for business. However, the NAV per share may be calculated at a time other than the normal close of the NYSE if trading on the NYSE is restricted, if the NYSE closes earlier, or as may be permitted by the SEC.

Fair Value The fund’s financial instruments are reported at fair value, which GAAP defines as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The T. Rowe Price Valuation Committee (the Valuation Committee) is an internal committee that has been delegated certain responsibilities by the fund’s Board of Trustees (the Board) to ensure that financial instruments are appropriately priced at fair value in accordance with GAAP and the 1940 Act. Subject to oversight by the Board, the Valuation Committee develops and oversees pricing-related policies and procedures and approves all fair value determinations. Specifically, the Valuation Committee establishes procedures to value securities; determines pricing techniques, sources, and persons eligible to effect fair value pricing actions; oversees the selection, services, and performance of pricing vendors; oversees valuation-related business continuity practices; and provides guidance on internal controls and valuation-related matters. The Valuation Committee reports to the Board and has representation from legal, portfolio management and trading, operations, risk management, and the fund’s treasurer.

Various valuation techniques and inputs are used to determine the fair value of financial instruments. GAAP establishes the following fair value hierarchy that categorizes the inputs used to measure fair value:

Level 1 – quoted prices (unadjusted) in active markets for identical financial instruments that the fund can access at the reporting date

Level 2 – inputs other than Level 1 quoted prices that are observable, either directly or indirectly (including, but not limited to, quoted prices for similar financial instruments in active markets, quoted prices for identical or similar financial instruments in inactive markets, interest rates and yield curves, implied volatilities, and credit spreads)

Observable inputs are developed using market data, such as publicly available information about actual events or transactions, and reflect the assumptions that market participants would use to price the financial instrument. Unobservable inputs are those for which market data are not available and are developed using the best information available about the assumptions that market participants would use to price the financial instrument. GAAP requires valuation techniques to maximize the use of relevant observable inputs and minimize the use of unobservable inputs. When multiple inputs are used to derive fair value, the financial instrument is assigned to the level within the fair value hierarchy based on the lowest-level input that is significant to the fair value of the financial instrument. Input levels are not necessarily an indication of the risk or liquidity associated with financial instruments at that level but rather the degree of judgment used in determining those values.

Valuation Techniques Debt securities generally are traded in the over-the-counter (OTC) market. Securities with remaining maturities of one year or more at the time of acquisition are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service, which considers the yield or price of bonds of comparable quality, coupon, maturity, and type, as well as prices quoted by dealers who make markets in such securities. Securities with remaining maturities of less than one year at the time of acquisition generally use amortized cost in local currency to approximate fair value. However, if amortized cost is deemed not to reflect fair value or the fund holds a significant amount of such securities with remaining maturities of more than 60 days, the securities are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service. Generally, debt securities are categorized in Level 2 of the fair value hierarchy; however, to the extent the valuations include significant unobservable inputs, the securities would be categorized in Level 3.

Assets and liabilities other than financial instruments, including short-term receivables and payables, are carried at cost, or estimated realizable value, if less, which approximates fair value.

Thinly traded financial instruments and those for which the above valuation procedures are inappropriate or are deemed not to reflect fair value are stated at fair value as determined in good faith by the Valuation Committee. The objective of any fair value pricing determination is to arrive at a price that could reasonably be expected from a current sale. Financial instruments fair valued by the Valuation Committee are primarily private placements, restricted securities, warrants, rights, and other securities that are not publicly traded.

Subject to oversight by the Board, the Valuation Committee regularly makes good faith judgments to establish and adjust the fair valuations of certain securities as events occur and circumstances warrant. For instance, in determining the fair value of troubled or thinly traded debt instruments, the Valuation Committee considers a variety of factors, which may include, but are not limited to, the issuer’s business prospects, its financial standing and performance, recent investment transactions in the issuer, strategic events affecting the company, market liquidity for the issuer, and general economic conditions and events. In consultation with the investment and pricing teams, the Valuation Committee will determine an appropriate valuation technique based on available information, which may include both observable and unobservable inputs. The Valuation Committee typically will afford greatest weight to actual prices in arm’s length transactions, to the extent they represent orderly transactions between market participants, transaction information can be reliably obtained, and prices are deemed representative of fair value. However, the Valuation Committee may also consider other valuation methods such as a discount or premium from market value of a similar, freely traded security of the same issuer; discounted cash flows; yield to maturity; or some combination. Fair value determinations are reviewed on a regular basis and updated as information becomes available, including actual purchase and sale transactions of the issue.

Because any fair value determination involves a significant amount of judgment, there is a degree of subjectivity inherent in such pricing decisions, and fair value prices determined by the Valuation Committee could differ from those of other market participants. Depending on the relative significance of unobservable inputs, including the valuation technique(s) used, fair valued securities may be categorized in Level 2 or 3 of the fair value hierarchy.

Valuation Inputs On August 31, 2017, all of the fund’s financial instruments were classified as Level 2, based on the inputs used to determine their fair values. There were no material transfers between Levels 1 and 2 during the six months ended August 31, 2017.

Consistent with its investment objective, the fund engages in the following practices to manage exposure to certain risks and/or to enhance performance. The investment objective, policies, program, and risk factors of the fund are described more fully in the fund’s prospectus and Statement of Additional Information.

Restricted Securities The fund may invest in securities that are subject to legal or contractual restrictions on resale. Prompt sale of such securities at an acceptable price may be difficult and may involve substantial delays and additional costs.

When-Issued Securities The fund may enter into when-issued purchase or sale commitments, pursuant to which it agrees to purchase or sell, respectively, an authorized but not yet issued security for a fixed unit price, with payment and delivery not due until issuance of the security on a scheduled future date. When-issued securities may be new securities or securities issued through a corporate action, such as a reorganization or restructuring. Until settlement, the fund maintains liquid assets sufficient to settle its commitment to purchase a when-issued security or, in the case of a sale commitment, the fund maintains an entitlement to the security to be sold. Amounts realized on when-issued transactions are included in realized gain/loss on securities in the accompanying financial statements.

Other Purchases and sales of portfolio securities other than short-term securities aggregated $40,893,000 and $16,444,000, respectively, for the six months ended August 31, 2017.

No provision for federal income taxes is required since the fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code and distribute to shareholders all of its income and gains. Distributions determined in accordance with federal income tax regulations may differ in amount or character from net investment income and realized gains for financial reporting purposes. Financial reporting records are adjusted for permanent book/tax differences to reflect tax character but are not adjusted for temporary differences. The amount and character of tax-basis distributions and composition of net assets are finalized at fiscal year-end; accordingly, tax-basis balances have not been determined as of the date of this report.

The fund intends to retain realized gains to the extent of available capital loss carryforwards. Because the fund is required to use capital loss carryforwards that do not expire before those with expiration dates, all or a portion of its capital loss carryforwards subject to expiration could ultimately go unused. As of February 28, 2017, the fund had $4,404,000 of available capital loss carryforwards, which expire as follows: $1,679,000 in fiscal 2018, and $43,000 in fiscal 2019; $2,682,000 have no expiration.

At August 31, 2017, the cost of investments for federal income tax purposes was $584,552,000. Net unrealized gain aggregated $36,899,000 at period-end, of which $38,737,000 related to appreciated investments and $1,838,000 related to depreciated investments.

The fund is managed by T. Rowe Price Associates, Inc. (Price Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. (Price Group). The investment management agreement between the fund and Price Associates provides for an annual investment management fee, which is computed daily and paid monthly. The fee consists of an individual fund fee, equal to 0.10% of the fund’s average daily net assets, and a group fee. The group fee rate is calculated based on the combined net assets of certain mutual funds sponsored by Price Associates (the group) applied to a graduated fee schedule, with rates ranging from 0.48% for the first $1 billion of assets to 0.265% for assets in excess of $650 billion. The fund’s group fee is determined by applying the group fee rate to the fund’s average daily net assets. At August 31, 2017, the effective annual group fee rate was 0.29%.

The I Class is subject to an operating expense limitation (I Class limit) pursuant to which Price Associates is contractually required to pay all operating expenses of the I Class, excluding management fees, interest, expenses related to borrowings, taxes, brokerage, and other non-recurring expenses permitted by the investment management agreement, to the extent such operating expenses, on an annualized basis, exceed 0.05% of average net assets. This agreement will continue until June 30, 2019, and may be renewed, revised, or revoked only with approval of the fund’s Board. The I Class is required to repay Price Associates for expenses previously paid to the extent the class’s net assets grow or expenses decline sufficiently to allow repayment without causing the class’s operating expense ratio (after the repayment is taken into account) to exceed the lesser of: (1) the expense limitation in place at the time such amounts were paid; and (2) the class’s current expense limitation. However, no repayment will be made more than three years after the date of a payment or waiver.

Pursuant to these agreements, $16,000 of expenses were waived/paid by Price Associates during the six months ended August 31, 2017 and remain subject to repayment by the fund.

In addition, the fund has entered into service agreements with Price Associates and a wholly owned subsidiary of Price Associates (collectively, Price). Price Associates provides certain accounting and administrative services to the fund. T. Rowe Price Services, Inc. provides shareholder and administrative services in its capacity as the fund’s transfer and dividend-disbursing agent. For the six months ended August 31, 2017, expenses incurred pursuant to these service agreements were $41,000 for Price Associates and $64,000 for T. Rowe Price Services, Inc. The total amount payable at period-end pursuant to these service agreements is reflected as Due to Affiliates in the accompanying financial statements.

As of August 31, 2017, T. Rowe Price Group, Inc., or its wholly owned subsidiaries owned 21,777 shares of the I Class, representing 3% of the I Class’s net assets.

The fund may participate in securities purchase and sale transactions with other funds or accounts advised by Price Associates (cross trades), in accordance with procedures adopted by the fund’s Board and Securities and Exchange Commission rules, which require, among other things, that such purchase and sale cross trades be effected at the independent current market price of the security. During the six months ended August 31, 2017, the fund had no purchases or sales cross trades with other funds or accounts advised by Price Associates.

On July 26, 2017 at a special meeting of the shareholders of the fund, the shareholders approved the redomiciliation and reorganization of the fund into the T. Rowe Price State Tax-Free Funds, Inc., effective October 30, 2017. The redomiciliation and reorganization will have no effect on the fund’s investment objective and strategies or on the fund’s net assets.

Each year, the fund’s Board of Trustees (Board) considers the continuation of the investment management agreement (Advisory Contract) between the fund and its investment advisor, T. Rowe Price Associates, Inc. (Advisor). In that regard, at an in-person meeting held on March 6–7, 2017 (Meeting), the Board, including a majority of the fund’s independent trustees, approved the continuation of the fund’s Advisory Contract. At the Meeting, the Board considered the factors and reached the conclusions described below relating to the selection of the Advisor and the approval of the Advisory Contract. The independent trustees were assisted in their evaluation of the Advisory Contract by independent legal counsel from whom they received separate legal advice and with whom they met separately.

In providing information to the Board, the Advisor was guided by a detailed set of requests for information submitted by independent legal counsel on behalf of the independent trustees. In considering and approving the Advisory Contract, the Board considered the information it believed was relevant, including, but not limited to, the information discussed below. The Board considered not only the specific information presented in connection with the Meeting but also the knowledge gained over time through interaction with the Advisor about various topics. The Board meets regularly and, at each of its meetings, covers an extensive agenda of topics and materials and considers factors that are relevant to its annual consideration of the renewal of the T. Rowe Price funds’ advisory contracts, including performance and the services and support provided to the funds and their shareholders.

Services Provided by the Advisor
The Board considered the nature, quality, and extent of the services provided to the fund by the Advisor. These services included, but were not limited to, directing the fund’s investments in accordance with its investment program and the overall management of the fund’s portfolio, as well as a variety of related activities such as financial, investment operations, and administrative services; compliance; maintaining the fund’s records and registrations; and shareholder communications. The Board also reviewed the background and experience of the Advisor’s senior management team and investment personnel involved in the management of the fund, as well as the Advisor’s compliance record. The Board concluded that it was satisfied with the nature, quality, and extent of the services provided by the Advisor.

Investment Performance of the Fund
The Board took into account discussions with the Advisor and reports that it receives throughout the year relating to fund performance. In connection with the Meeting, the Board reviewed the fund’s net annualized total returns for the 1-, 2-, 3-, 4-, 5- and 10-year periods as of September 30, 2016, and compared these returns with the performance of a peer group of funds with similar investment programs and a wide variety of other previously agreed-upon comparable performance measures and market data, including those supplied by Broadridge, which is an independent provider of mutual fund data.

On the basis of this evaluation and the Board’s ongoing review of investment results, and factoring in the relative market conditions during certain of the performance periods, the Board concluded that the fund’s performance was satisfactory.

Costs, Benefits, Profits, and Economies of Scale
The Board reviewed detailed information regarding the revenues received by the Advisor under the Advisory Contract and other benefits that the Advisor (and its affiliates) may have realized from its relationship with the fund, including any research received under “soft dollar” agreements and commission-sharing arrangements with broker-dealers. The Board considered that the Advisor may receive some benefit from soft-dollar arrangements pursuant to which research is received from broker-dealers that execute the fund’s portfolio transactions. The Board received information on the estimated costs incurred and profits realized by the Advisor from managing the T. Rowe Price funds. The Board also reviewed estimates of the profits realized from managing the fund in particular, and the Board concluded that the Advisor’s profits were reasonable in light of the services provided to the fund.

The Board also considered whether the fund benefits under the fee levels set forth in the Advisory Contract from any economies of scale realized by the Advisor. Under the Advisory Contract, the fund pays a fee to the Advisor for investment management services composed of two components—a group fee rate based on the combined average net assets of most of the T. Rowe Price funds (including the fund) that declines at certain asset levels and an individual fund fee rate based on the fund’s average daily net assets—and the fund pays its own expenses of operations. At the Meeting, the Board approved an additional 0.005% breakpoint to the group fee schedule, effective May 1, 2017. With the new breakpoint, the group fee rate will decline to 0.265% when the combined average net assets of the applicable T. Rowe Price funds exceed $650 billion. The Board concluded that the advisory fee structure for the fund continued to provide for a reasonable sharing of benefits from any economies of scale with the fund’s investors.

Fees and Expenses
The Board was provided with information regarding industry trends in management fees and expenses. Among other things, the Board reviewed data for peer groups that were compiled by Broadridge, which compared: (i) contractual management fees, total expenses, actual management fees, and non-management expenses of the fund with a group of competitor funds selected by Broadridge (Expense Group) and (ii) total expenses, actual management fees, and non-management expenses of the fund with a broader set of funds within the Lipper investment classification (Expense Universe). The Board considered the fund’s contractual management fee rate, actual management fee rate (which reflects the management fees actually received from the fund by the Advisor after any applicable waivers, reductions, or reimbursements), operating expenses, and total expenses (which reflects the net total expense ratio of the fund after any waivers, reductions, or reimbursements) in comparison with the information for the Broadridge peer groups. Broadridge generally constructed the peer groups by seeking the most comparable funds based on similar investment classifications and objectives, expense structure, asset size, and operating components and attributes and ranked funds into quintiles, with the first quintile representing the funds with the lowest relative expenses and the fifth quintile representing the funds with the highest relative expenses. The information provided to the Board indicated that the fund’s contractual management fee ranked in the first quintile (Expense Group), the fund’s actual management fee rate ranked in the second quintile (Expense Group and Expense Universe), and the fund’s total expenses ranked in the second quintile (Expense Group) and first quintile (Expense Universe).

The Board also reviewed the fee schedules for institutional accounts and private accounts with similar mandates that are advised or subadvised by the Advisor and its affiliates. Management provided the Board with information about the Advisor’s responsibilities and services provided to subadvisory and other institutional account clients, including information about how the requirements and economics of the institutional business are fundamentally different from those of the mutual fund business. The Board considered information showing that the Advisor’s mutual fund business is generally more complex from a business and compliance perspective than its institutional account business and considered various relevant factors, such as the broader scope of operations and oversight, more extensive shareholder communication infrastructure, greater asset flows, heightened business risks, and differences in applicable laws and regulations associated with the Advisor’s proprietary mutual fund business. In assessing the reasonableness of the fund’s management fee rate, the Board considered the differences in the nature of the services required for the Advisor to manage its mutual fund business versus managing a discrete pool of assets as a subadvisor to another institution’s mutual fund or for an institutional account and that the Advisor generally performs significant additional services and assumes greater risk in managing the fund and other T. Rowe Price funds than it does for institutional account clients.

On the basis of the information provided and the factors considered, the Board concluded that the fees paid by the fund under the Advisory Contract are reasonable.

Approval of the Advisory Contract
As noted, the Board approved the continuation of the Advisory Contract. No single factor was considered in isolation or to be determinative to the decision. Rather, the Board concluded, in light of a weighting and balancing of all factors considered, that it was in the best interests of the fund and its shareholders for the Board to approve the continuation of the Advisory Contract (including the fees to be charged for services thereunder).
