Your expenses

These examples are intended to help you understand your ongoing operating expenses of investing in the fund so you can compare these costs with the ongoing costs of investing in other mutual funds.

Understanding your fund expenses

As a shareholder of the fund, you incur two types of costs:

● Transaction costs which include sales charges (loads) on purchases or redemptions (if applicable), minimum account fee charge, etc.

● Ongoing operating expenses including management fees, distribution and service fees (if applicable), and other fund expenses.

We are going to present only your ongoing operating expenses here.

Actual expenses/actual returns

This example is intended to provide information about your fund’s actual ongoing operating expenses, and is based on your fund’s actual return. It assumes an account value of $1,000.00 on January 1, 2014, with the same investment held until June 30, 2014.

	Account value	Ending value	Expenses paid during	Annualized
	on 1-1-14	on 6-30-14	period ended 6-30-141	expense ratio
Shares	$1,000.00	$1,000.70	$0.40	0.08%

Together with the value of your account, you may use this information to estimate the operating expenses that you paid over the period. Simply divide your account value at June 30, 2014, by $1,000.00, then multiply it by the “expenses paid” from the table above. For example, for an account value of $8,600.00, the operating expenses should be calculated as follows:

Example

[ My account value $8,600.00 / $1,000.00 = 8.6 ] x $[ “expenses paid” from table ] = My actual expenses

Hypothetical example for comparison purposes

This table allows you to compare your fund’s ongoing operating expenses with those of any other fund. It provides an example of the fund’s hypothetical account values and hypothetical expenses based on the fund’s actual expense ratio and an assumed 5% annualized return before expenses (which is not your fund’s actual return). It assumes an account value of $1,000.00 on January 1, 2014, with the same investment held until June 30, 2014. Look in any other fund shareholder report to find its hypothetical example and you will be able to compare these expenses. Please remember that these hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

	Account value	Ending value	Expenses paid during	Annualized
	on 1-1-14	on 6-30-14	period ended 6-30-141	expense ratio
Shares	$1,000.00	$1,024.40	$0.40	0.08%

Remember, these examples do not include any transaction costs, therefore, these examples will not help you to determine the relative total costs of owning different funds. If transaction costs were included, your expenses would have been higher. See the prospectus for details regarding transaction costs.

¹ Expenses are equal to the fund's annualized expense ratio of 0.08%, for the fund’s shares, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

² Sector investing is subject to greater risks than the market as a whole. Because the fund may focus on particular sectors of the economy, its performance may depend on the performance of those sectors and investments focused in one sector may fluctuate more widely than investments diversified across sectors.

* Yield represents either the annualized yield at the date of purchase, the stated coupon rate or, for floating rate securities, the rate at period end.

John Hancock Collateral Investment Trust

Notes to financial statements (Unaudited)

Note 1 — Organization

John Hancock Collateral Investment Trust (the fund) is a Massachusetts business trust organized on May 19, 2009. The fund is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act). However, beneficial interests of the fund are not being registered under the Securities Act of 1933, as amended. The current investors in the fund are investment companies advised by affiliates of John Hancock Asset Management, a division of Manulife Asset Management (US) LLC, the fund’s investment advisor (the Advisor). The fund serves primarily as an investment vehicle for cash received as collateral by such affiliated funds for participation in securities lending.

The investment objective of the fund is to seek current income, while maintaining adequate liquidity, safeguarding the return of principal and minimizing risk of default. The fund invests only in U.S. dollar denominated securities rated, at the time of investment, within the two highest short-term credit categories and their unrated equivalents. The fund’s net asset value (NAV) varies daily.

Note 2 - Significant accounting policies

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (US GAAP), which require management to make certain estimates and assumptions as of the date of the financial statements. Actual results could differ from those estimates and those differences could be significant. The fund qualifies as an investment company under Topic 946 of the Accounting Standards Codification of US GAAP, and there have been no changes to this qualification during the periods presented in the financial statements.

Events or transactions occurring after the end of the fiscal period through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the fund:

Security valuation. Investments are stated at value as of the close of regular trading on the New York Stock Exchange (NYSE), normally at 4:00 P.M., Eastern Time. In order to value the securities, the fund uses the following valuation techniques: Debt obligations are valued based on the evaluated prices provided by an independent pricing vendor or from broker-dealers. Independent pricing vendors utilize matrix pricing which takes into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data, as well as broker supplied prices. Securities that trade only in the over-the-counter market are valued using bid prices. Certain short-term securities with maturities of 60 days or less at the time of purchase are valued at amortized cost. Other fund securities and assets, for which reliable market quotations are not readily available, are valued at fair value as determined in good faith by the fund’s Pricing Committee following procedures established by the Board of Trustees. The frequency with which these fair valuation procedures are used cannot be predicted and fair value of securities may differ significantly from the value that would have been used had a ready market for such securities existed.

The fund uses a three-tier hierarchy to prioritize the pricing assumptions, referred to as inputs, used in valuation techniques to measure fair value. Level 1 includes securities valued using quoted prices in active markets for identical securities. Level 2 includes securities valued using other significant observable inputs. Observable inputs may include quoted prices for similar securities, interest rates, prepayment speeds and credit risk. Prices for securities valued using these inputs are received from independent pricing vendors and brokers and are based on an evaluation of the inputs described. Level 3 includes securities valued using significant unobservable inputs when market prices are not readily

available or reliable, including the fund’s own assumptions in determining the fair value of investments. Factors used in determining value may include market or issuer specific events or trends, changes in interest rates and credit quality. The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. Changes in valuation techniques may result in transfers into or out of an assigned level within the disclosure hierarchy. As of June 30, 2014, all investments are categorized as Level 2 under the hierarchy described above.

Repurchase agreements. The fund may enter into repurchase agreements. When the fund enters into a repurchase agreement, it receives collateral that is held in a segregated account by the fund’s custodian, or for tri-party repurchase agreements, collateral is held at a third-party custodian bank in a segregated account for the benefit of the fund. The collateral amount is marked-to-market and monitored on a daily basis to ensure that the collateral held is in an amount not less than the principal amount of the repurchase agreement plus any accrued interest. Collateral received by the fund for repurchase agreements is disclosed in the Portfolio of investments as part of the caption related to the repurchase agreement.

Repurchase agreements are typically governed by the terms and conditions of the Master Repurchase Agreement and/or Global Master Repurchase Agreement (collectively, MRA). Upon an event of default, the non-defaulting party may close out all transactions traded under the MRA and net amounts owed. Absent an event of default, the MRA does not result in an offset of the reported amounts of assets and liabilities in the Statement of assets and liabilities. In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the collateral value may decline or the counterparty may have insufficient assets to pay back claims resulting from close-out of the transactions.

Security transactions and related investment income. Investment security transactions are recorded as of the date of purchase, sale or maturity. Interest income is accrued as earned. Interest income includes coupon interest and amortization/accretion of premiums/discounts on debt securities. Debt obligations may be placed in a non-accrual status and related interest income may be reduced by stopping current accruals and writing off interest receivable when the collection of all or a portion of interest has become doubtful. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds from litigation.

Expenses. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Federal income taxes. The fund intends to continue to qualify as a regulated investment company by complying with the applicable provisions of the Internal Revenue Code and will not be subject to federal income tax on taxable income that is distributed to shareholders. Therefore, no federal income tax provision is required.

Under the Regulated Investment Company Modernization Act of 2010, the fund is permitted to carry forward capital losses for an unlimited period. Capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law.

For federal income tax purposes, as of December 31, 2013, the fund has a short-term capital loss carryforward of $6,997 available to offset future net realized capital gains. These carryforwards do not expire.

As of December 31, 2013, the fund had no uncertain tax positions that would require financial statement recognition, derecognition or disclosure. The fund’s federal tax returns are subject to examination by the Internal Revenue Service for a period of three years.

13 

Distribution of income and gains. Distributions to shareholders from net investment income and net realized gains, if any, are recorded on the ex-date. The fund generally declares dividends daily and pays them monthly. Capital gain distributions, net of fees paid to the fund’s securities lending agent, if any, are distributed annually.

Such distributions, on a tax basis, are determined in conformity with income tax regulations, which may differ from accounting principles generally accepted in the United States of America.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences, if any, will reverse in a subsequent period.

Note 3 - Guarantees and indemnifications

Under the fund’s organizational documents, its Officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into contracts with service providers that contain general indemnification clauses. The fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the fund that have not yet occurred. The risk of material loss from such claims is considered remote.

Note 4 – Fees and transactions with affiliates

The Advisor serves as investment advisor for the fund. John Hancock Funds, LLC (the Placement Agent) performs services related to the offering and sale of shares of the fund. The Advisor and the Placement Agent are indirect wholly owned subsidiaries of Manulife Financial Corporation.

Management fee. The fund has an investment management contract with the Advisor. Under the investment management contract, the fund pays a daily management fee to the Advisor at the annual rate of: (a) 0.05% of the first $1,500,000,000 of the fund’s average daily net assets and (b) 0.03% of the fund’s average daily net assets in excess of $1,500,000,000.

The investment management fees incurred for the six months ended June 30, 2014 were equivalent to an annual effective rate of 0.040% of the fund’s average daily net assets.

Administrative services. The fund has entered into an Administrative Services Agreement with John Hancock Advisers, LLC (“JHA”) under which JHA provides accounting, valuation, financial reporting and certain other services for an annual fee of 0.02% of the fund's average daily net assets. JHA has voluntarily undertaken to limit its total annual fee to $300,000. The administrative service fees incurred for the six months ended June 30, 2014 were equivalent to an annual effective rate of 0.01% of the fund’s average daily net assets.

Chief Compliance Officer services. The fund has contracted with the Advisor and the fund’s Chief Compliance Officer (CCO) to provide certain services, including ongoing evaluation of the fund’s policies and procedures under the federal securities laws. In addition, the CCO will provide annual reporting to the Board of Trustees detailing the results of this review. The fund pays an annual flat rate of $35,000 to the Advisor, paid monthly in arrears, for these services.

Trustee expenses. The fund compensates each Trustee who is not an employee of the Advisor or its affiliates.

Transfer agent fees. The fund has a transfer agent agreement with John Hancock Signature Services, Inc. (the Transfer Agent), an affiliate of the Advisor. Monthly, the fund pays the Transfer Agent a fee which is based on an annual rate of $100,000. The fund also pays certain out-of-pocket expenses to the Transfer Agent.

Evaluation of the Investment Management Contract by the Board of Trustees

This section describes the evaluation by the Board of Trustees (the “Board”) of John Hancock Collateral Investment Trust (the “Trust”), including the Trustees who are not “interested persons” of the Trust as defined in the Investment Company Act of 1940, as amended (“Independent Trustees”), of the Investment Management Contract (the “Management Contract”) between the Trust and Manulife Asset Management (US), LLC (the “Advisor”) that took place at an in-person meeting of the Board on February 11, 2014 (the “Meeting”). In considering the continuance of the Management Contract, the Board, including the Independent Trustees, considered the following factors:

The Nature, Extent and Quality of Services Provided by the Adviser

The Board considered the value to the Trust of its relationship with the Adviser, in particular noting the Adviser’s reputation in the asset management industry and the skills and competency with which the Adviser has managed the affairs of the Trust and other affiliated funds, together with the Adviser’s investment philosophy, research and investment decision-making process. The Board also particularly noted the experience and performance of the Adviser in managing the Trust, the qualifications of the Adviser’s personnel, the commitment of the Adviser and its personnel to the Trust’s successful operation and management and the Adviser’s ability to attract and retain qualified investment professionals, including research, advisory and supervisory personnel.

Additionally, the Board considered the Adviser’s compliance policies and procedures and the Adviser’s record of compliance with those policies and procedures, noting in particular the Adviser’s dedication to its compliance program, the lack of any material compliance incidents and the Adviser’s culture of compliance. The Board also considered the Adviser’s administrative capabilities and its ability to supervise other service providers for the Trust and to draw upon its organizational resources and affiliated companies to enhance the services it provides to the Trust.

Advisory Fees, Expenses and Investment Performance of the Trust

The Board considered information it had received regarding the advisory fees charged by the Adviser and the other expenses borne by the Trust, including administrative fees, transfer agent fees, custodial fees and other miscellaneous fees and expenses. The Board also considered information it had received regarding the Trust’s investment performance for the year ended December 31, 2013. The Board reviewed and considered the comparative advisory fee and performance information for a selected peer group of five other funds that, like the Trust, are vehicles for the investment of cash collateral from securities lending programs (the “Peer Group”). The Board noted that no members of the Peer Group operated in a manner exactly like the Trust – i.e., as a 1940 Act-registered fund investing in money market instruments and maintaining a floating net asset value – but that the members of the Peer Group were sufficiently comparable to the Trust for a meaningful analysis.

16 

The Board noted that the Adviser charged the Trust an advisory fee of 0.05% of the Trust’s first $1.5 billion of average daily net assets and 0.03% of the Trust’s average daily net assets in excess of $1.5 billion. The Board acknowledged that, for the year ended December 31, 2013, this resulted in an effective advisory fee rate of 0.036% of the Trust’s average daily net assets. The Board compared this effective advisory fee rate to those of the Peer Group, and noted that it was on the low end of the advisory fee rates of the Peer Group. The Board then further noted that the Trust’s average net yield as of December 31, 2013 was 0.16%, as compared to the Peer Group, whose average net yields ranged from 0.12% to 0.19% as of December 31, 2013. There was then a discussion of the fees charged by the Adviser to other non-investment company clients for similar services. It was noted that the fees charged to the Trust compared favorably to the fees charged to such other clients.

Upon reviewing and considering the foregoing information and considering the overall expenses and performance of the Trust over various periods and since its inception, the Board concluded that the Adviser’s performance was exemplary, and in particular noted the fact that the Trust achieved a high net yield relative to the Peer Group while the Adviser maintained a low rate of compensation relative to the Peer Group.

Economies of Scale

The Board also considered general information regarding economies of scale with respect to the management of the Trust, including the Trust’s ability to appropriately benefit from economies of scale under the Trust’s fee structure, which included a breakpoint at $1.5 billion average daily net assets. The Board recognized the inherent limitations of any analysis of economies of scale, stemming largely from the Board’s understanding that most of the Adviser’s costs are not specific to individual funds, but rather are incurred across a variety of products and services and would generally stem from the Adviser’s common corporate ownership or shared services. To the extent the Board and the Adviser were able to identify actual or potential economies of scale, in order to ensure that any such economies continue to be reasonably shared with the Trust as its assets increase, the Adviser and the Board agreed to continue the existing breakpoints to the advisory fee rate.

Financial Condition and Profitability of, and Other Benefits to, the Adviser

The Board also took into consideration information regarding the Adviser’s estimated net profit pre-tax operating income attributable to its management of the Trust, and noted that the Trust’s affiliated service providers (other than the Adviser) were providing their services based upon estimated costs or for a nominal fee and such affiliated service providers, where applicable, reflected economies of scale in such fees. The Board also considered the Adviser’s views as to its projected profitability in connection with its relationship with the Trust in terms of the total amount of annual management fees it is projected to receive with respect to the Trust and whether the Adviser has the financial ability to provide a high level of services to the Trust. Additionally, the Board considered the Adviser’s unaudited balance sheet as of December 31, 2013 and noted the Adviser’s strong capitalization and financial condition and considered favorably the Adviser’s representation that it sought to reinvest profits and retained earnings in its business.

17 

The Board also considered information it had received regarding any additional, indirect or “fall out” benefits to the Adviser as a result of its management of the Trust. The Board noted in particular that the Trust invests in fixed-income money market securities, which are generally traded in an over-the-counter market and are generally purchased from the issuer or a primary market maker acting as principal on a net basis with no stated brokerage commission paid by the Trust. The Board recognized that, in these markets, any commission or net markup (or markdown) was implied by the difference or “spread” between the price the dealer purchases the bond for and the price the dealer sells the bond at. In this regard, the Board considered the quality of the execution achieved for the Trust by the Adviser, noted its satisfaction with the Adviser’s performance and recognized the Adviser's representation that it did not use Trust assets to obtain research or other services from dealers it trades with on a principal basis.

The Board noted, however, that the Adviser does generate soft dollars in the management of other accounts and that the Adviser does receive proprietary broker research as part of the “bundle” of brokerage and research services in which the research is not separately priced. The Board recognized that research and brokerage services provided in connection with one account may be used to benefit all of the Adviser’s and its affiliates’ accounts and noted again its satisfaction with the quality of execution achieved for the Trust by the Adviser.

The Board discussed the Adviser's representations regarding the operation of the securities lending program for other funds managed by the Adviser and its affiliates of which the Trust was an integral part.

The Board also considered the various other service agreements that the Trust has with the Adviser’s affiliates, including the Service Agreement (for administrative services), the Placement Agency Agreement, the Transfer Agency Agreement, the CCO Services Agreement and the IT Support Services Agreement. The Board reviewed and considered the terms of each of these agreements and the services provided thereunder, together with the fees charged under these agreements. After reviewing these service arrangements, and based on the representations of the Adviser, the Board concluded that each such service agreement was in the best interests of the Trust and its shareholders, that the services performed pursuant to each such service agreement are required for the operation of the Trust, that each such service provider provides services the nature and quality of which are at least equal to those provided by other unaffiliated service providers offering the same or similar services, and that the fees charged under each such service agreement are fair and reasonable in light of the usual and customary charges made by other unaffiliated service providers for services of the same nature and quality.

The Board concluded that, in light of the costs of providing investment management and other services to the Trust, the profits and other ancillary benefits reported by the Adviser were not unreasonable.

18 

Other Considerations and Conclusion

The Board also generally took into account the level and quality of services that the Adviser is capable of providing, as well as all of the information presented and other factors considered at the Meeting and at previous Board meetings.

As a result of the above considerations and discussion with management of the Adviser during the Meeting, the Board, though it did not identify any one factor as controlling, concluded that: (i) the Adviser may reasonably be expected to perform its services under the Management Contract; (ii) although economies of scale cannot be measured with precision, the management fee breakpoint currently allows shareholders to benefit from economies of scale; and (iii) the Trust’s management fees are generally within a competitive range of those incurred by other comparable funds.
