A message to shareholders

Dear fellow shareholder,

Robust economic growth in the United States set the global standard in 2014. The portfolio teams in our network are generally optimistic about continued relative strength in the United States, supported by rising employment, healthy consumer spending, and falling oil prices. Stocks at all-time highs remain vulnerable to a correction, but the long-term bull market appears intact. We believe a more selective approach continues to make sense in overseas markets, but note that opportunities are growing and could reward investors should recoveries in those markets begin in earnest.

The coming year will likely present greater challenges for bond investors, however. The U.S. Federal Reserve has signaled its intention to raise short-term interest rates in 2015, and that change will have an adverse effect on many fixed-income portfolios, particularly those that invest in less liquid markets. At John Hancock Investments, we are closely monitoring our fixed-income portfolios and communicating regularly with their portfolio managers about these issues. Now may also be a good time for you to discuss your fixed-income strategy with your financial advisor to determine if that portion of your portfolio continues to match your long-term goals.

A new look

I am pleased to introduce you to our redesigned shareholder reports. As part of an effort to elevate the educational substance in our communications, we undertook an initiative to make our reports more engaging and easier to navigate. Included in the changes are a performance snapshot that shows your fund's performance against that of its benchmark, and a Q&A with your fund's lead portfolio manager. We hope these enhancements give you better insight into your fund's activity and performance.

On behalf of everyone at John Hancock Investments, I'd like to take this opportunity to thank you for the continued trust you've placed in us.

Sincerely,

Andrew G. Arnott
President and Chief Executive Officer
John Hancock Investments

INVESTMENT OBJECTIVE

The fund seeks current income while maintaining adequate liquidity, safeguarding the return of principal and minimizing risk of default.

AVERAGE ANNUAL TOTAL RETURNS AS OF 12/31/14(%)

The Bank of America Merrill Lynch 3-Month U.S. Treasury Bill Index is composed of a single issue purchased at the beginning of the month and held for a full month. Each month the index is rebalanced and the issue selected is the outstanding U.S. Treasury Bill that matures closest to, but not beyond, three months from the rebalancing date.

It is not possible to invest directly in an index. Index figures do not reflect expenses, which would have resulted in lower values

The past performance shown here assumes reinvested distributions and the beneficial effect of any expense reductions, and does not guarantee future results. Returns for periods shorter than one year are cumulative. Shares will fluctuate in value and, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance cited, and can be found at jhinvestments.com or by calling 800-225-5291. For further information on the fund's objectives, risks, and strategy, see the fund's registration statement.

PERFORMANCE HIGHLIGHTS OVER THE LAST TWELVE MONTHS

Fed set the stage for rate hikes

While the federal funds rate remained unchanged all year, the Fed wrapped up its asset repurchase program in October.

Fund shortened its maturity profile

The fund's maturity profile was shortened to accommodate liquidity needs and a relatively flat yield curve.

PORTFOLIO COMPOSITION AS OF 12/31/14 (%)

A note about risks

Fixed-income investments are subject to interest-rate and credit risk; their value will normally decline as interest rates rise or if a creditor or grantor is unable or unwilling to make principal or interest payments. Investing in foreign securities may entail the risk of currency fluctuations or heightened economic and political instability. Events in the financial markets have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. In addition, reduced liquidity in credit and fixed-income markets may adversely affect issuers worldwide. Certain market conditions, including reduced trading volume, heightened volatility, or rising interest rates, may impair liquidity, the ability of the fund to sell securities at advantageous prices. A portfolio concentrated in one sector or that holds a limited number of securities may fluctuate more than a diversified portfolio. Investments in a non-diversified fund may magnify the fund's losses from adverse events affecting a particular issuer. A fund that invests in particular sectors is particularly susceptible to the impact of market, economic, regulatory, and other factors affecting those sectors. Please see the fund's registration statement for additional risks.

Discussion of fund performance

An interview with Portfolio Manager Jeffrey N. Given, CFA, John Hancock Asset Management a division of Manulife Asset Management (US) LLC

Jeffrey N. Given, CFA
Portfolio Manager
John Hancock
Asset Management

What factors impacted the market over the past year?

The year started off somewhat sluggish with mixed economic data, blamed in part by adverse winter weather, leading to very low volatility in the second quarter with the U.S. economy showing slow improvements. Geopolitical unrest and conflicts abroad led the headlines in the third quarter, bringing volatility back into the U.S. and global markets. This was amplified in the fourth quarter with weak global growth data, lower inflation expectations, and a dramatic drop in oil prices. Year over year, the U.S. unemployment rate decreased from 6.7% to 5.8%, the lowest level since 2008. However, the labor force participation rate remained rangebound between 62.7%- 63.2%, ending the year at 62.8%, and disappointing hourly and weekly earnings numbers curbed the enthusiasm of the unemployment rate drop.

The U.S. Federal Reserve (Fed) continued to taper its asset purchase program in $10 billion increments, officially ending the program during the October Federal Open Market Committee meeting, raising speculation of the Fed's timing of the first rate hike. The federal funds rate remained unchanged all year at 0.00%-0.25%. The three-month London Interbank Offered Rate began the year at 24.30 basis points and ended slightly up at 25.56 basis points.

How did these occurrences impact the fund?

Throughout the year we shortened up the maturity profile of the fund to accommodate increased liquidity needs and a relatively flat yield curve. Year over year, the only material change in sector distribution was a decrease in corporate bond exposure. This decrease was mostly in response to adding liquidity in the 1-month maturity bucket via shorter investments. In the 0-30-day average maturity bucket, we increased the fund's weight from under 50.0% of assets up to 67.4%. Similiarly, we decreased the fund's weight in the over-90-day average maturity bucket from over 25.0% down to 7.2% of net assets. Although the weighted average maturity and weighted average life of the portfolio decreased (to 26 days and 51 days, respectively), the fund's gross yield remained relatively stable throughout the year.

"... with risks of slower global growth, and continued liquidity and balance sheet concerns due to increased regulations, we will continue to invest in the safest assets and maintain a conservative stance for the fund, highlighting liquidity, diversification, and quality."

How did you position the fund at the end of the period?

Strong U.S. economic data hints that the Fed may be preparing for a mid-to-late 2015 rate hike, but continued low inflation, weak global economic data, and stagnant growth in the eurozone may curb any certainty. We expect short-term rates to drift up slightly in 2015 in response to anticipation of a Fed rate hike, but ultimately we do not see spreads widening out significantly due to continued expectations of high demand and low supply. As always, with risks of slower global growth, and continued liquidity and balance sheet concerns due to increased regulations, we will continue to invest in the safest assets and maintain a conservative stance for the fund, highlighting liquidity, diversification, and quality.

A look at performance

TOTAL RETURNS FOR THE PERIOD ENDED DECEMBER 31, 2014


Average annual total returns (%)				Cumulative total returns (%)
	1-year	5-year	Since Inception¹		5-year	Since Inception¹
John Hancock Collateral Investment Trust	0.11	0.24	0.26		1.19	1.48
Index^†	0.03	0.09	0.10		0.45	0.57

Performance figures assume all distributions are reinvested.

The expense ratio of the fund is set forth according to the Financial highlights of the fund's annual report dated December 31, 2013. The net expenses equal the gross expenses of 0.06%.

The returns reflect past results and should not be considered indicative of future performance. The return and principal value of an investment will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Due to market volatility, the fund's current performance may be higher or lower than the performance shown. For current to the most recent month-end performance data, please call 800-225-5291 or visit the fund's website at jhinvestments.com.

The performance table above and the chart below do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. The fund's performance results reflect any applicable fee waivers or expense reductions, without which the expenses would increase and results would have been less favorable.

†	Index is the Bank of America Merrill Lynch 3-Month U.S. Treasury Bill Index.

This chart shows what happened to a hypothetical $10,000 investment in John Hancock Collateral Investment Trust for the periods indicated, assuming all distributions were reinvested. For comparison, we've shown the same investment in the Bank of America Merrill Lynch 3-Month U.S. Treasury Bill Index.

The Bank of America Merrill Lynch 3-Month U.S. Treasury Bill Index is comprised of a single issue purchased at the beginning of the month and held for a full month. Each month the index is rebalanced and the issue selected is the outstanding U.S. Treasury Bill that matures closest to, but not beyond, three months from the rebalancing date.

It is not possible to invest directly in an index. Index figures do not reflect sales charges or direct expenses, which would have resulted in lower values.

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 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 (varies by share class), minimum account fee charge, etc.
•	Ongoing operating expenses, including management fees, distribution and service fees (if applicable), and other fund expenses.

We are presenting only your ongoing operating expenses here.

Actual expenses/actual returns

This example is intended to provide information about the fund's actual ongoing operating expenses, and is based on the fund's actual return. It assumes an account value of $1,000.00 on July 1, 2014, with the same investment held until December 31, 2014.


	Account value on 7-1-2014	Ending value on 12-31-2014	Expenses paid during period ended 12-31-2014¹	Annualized expense ratio
Shares	$1,000.00	$1,000.40	$0.50	0.10%

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 December 31, 2014, by $1,000.00, then multiply it by the "expenses paid" for your share class from the table above. For example, for an account value of $8,600.00, the operating expenses should be calculated as follows:

Hypothetical example for comparison purposes

This table allows you to compare the 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 the fund's actual return). It assumes an account value of $1,000.00 on July 1, 2014, with the same investment held until December 31, 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 on 7-1-2014	Ending value on 12-31-2014	Expenses paid during period ended 12-31-2014¹	Annualized expense ratio
Shares	$1,000.00	$1,024.70	$0.51	0.10%

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, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period).

Notes to financial statements

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 maximize 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.

At the close of business on January 30, 2015, the fund transferred its net assets to the John Hancock Collateral Trust (JHCT). Shareholders of the fund received shares in JHCT equal to their interest in the fund. The investment objective of JHCT and the fund are similar. The Board of Trustees approved liquidation of the fund on February 12, 2015.

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 Accounting Standards Codification of US GAAP.

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 portfolio 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 December 31, 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 Fund's 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 accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment transactions are reported on trade date. 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, 2014, the fund has a short-term capital loss carryforward of $6,997 available to offset future net realized capital gains. This carryforward does not expire.

As of December 31, 2014, 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.

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 gains distributions, net of fees paid to the fund's securities lending agent, if any, are distributed annually. The tax character of distributions for the years ended December 31, 2014 and 2013 was as follows:


	December 31, 2014	December 31, 2013
Ordinary Income	$3,498,923	$10,146,837

Such distributions and distributable earnings, on a tax basis, are determined in conformity with income tax regulations, which may differ from US GAAP. Distributions in excess of tax basis earnings and profits, if any, are reported in the fund's financial statements as a return of capital.

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. The fund had no material book-tax differences at December 31, 2014.

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 Placement Agent are indirect wholly owned subsidiaries of Manulife Financial Corporation.

Management fee. The fund has an investment management agreement 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 $1.5 billion of the fund's average daily net assets and (b) 0.03% of the fund's average daily net assets in excess of $1.5 billion.

The investment management fees incurred for the year ended December 31, 2014 were equivalent to a net annual effective rate of 0.04% 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 year ended December 31, 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.

Note 5 — Fund share transactions

AUDITOR'S REPORT

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of John Hancock Collateral Investment Trust:

In our opinion, the accompanying statement of assets and liabilities, including the fund's investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of John Hancock Collateral Investment Trust (the "Fund") at December 31, 2014, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2014 by correspondence with the custodian and the application of alternative auditing procedures where securities purchased confirmations had not been received, provide a reasonable basis for the opinion expressed above.

As disclosed in Note 1 of the Notes to financial statements, the Board of Trustees approved a plan of liquidation on February 12, 2015. Our opinion is not modified with respect to this matter.

ITEM 2. CODE OF ETHICS.

As of the end of the year, December 31, 2014, the registrant has adopted a code of ethics, as defined in Item 2 of Form N-CSR, that applies to its Chief Executive Officer, Chief Financial Officer and Treasurer (respectively, the principal executive officer, the principal financial officer and the principal accounting officer, the “Senior Financial Officers”). A copy of the code of ethics is filed as an exhibit to this Form N-CSR.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The Trustees have determined that a member of the audit committee, Mr. John Frabotta, is an audit committee financial expert. Mr. Frabotta is an independent trustee by virtue of being not an "interested" person of the Trust (as defined under the Investment Company Act of 1940, as amended) whose sole compensation from the Trust is his Trustees' fees.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a) Audit Fees

The aggregate fees billed for professional services rendered by the principal accountant(s) for the audit of the registrant’s annual financial statements or services that are normally provided by the accountant(s) in connection with statutory and regulatory filings or engagements amounted to $55,423 for the fiscal year ended December 31, 2014 and $53,817 for the fiscal year ended December 31, 2013 for John Hancock Collateral Investment Trust. These fees were billed to the registrant and were approved by the registrant’s audit committee.

In addition, amounts billed to control affiliates for service provider internal controls reviews were $103,940 and $98,642 for the fiscal years ended December 31, 2014 and 2013, respectively.

The aggregate fees billed for professional services rendered by the principal accountant(s) for the tax compliance, tax advice and tax planning (“tax fees”) amounted to $2,700 for the fiscal year ended December 31, 2014 and $2,785 for the fiscal year ended December 31, 2013 for John Hancock Collateral Investment Trust.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

The trust’s Audit Committee must pre-approve all audit and non-audit services provided by the independent registered public accounting firm (the “Auditor”) relating to the operations or financial reporting of the funds. Prior to the commencement of any audit or non-audit services to a fund, the Audit Committee reviews the services to determine whether they are appropriate and permissible under applicable law.

The trust’s Audit Committee has adopted policies and procedures to, among other purposes, provide a framework for the Committee’s consideration of audit-related and non-audit services by the Auditor. The policies and procedures require that any audit-related and non-audit service provided by the Auditor and any non-audit service provided by the Auditor to a fund service provider that relates directly to the operations and financial reporting of a fund are subject to approval by the Audit Committee before such service is provided. Audit-related services provided by the Auditor that are expected to exceed $10,000 per instance/per fund are subject to specific pre-approval by the Audit Committee. Tax services provided by the Auditor that are expected to exceed $10,000 per instance/per fund are subject to specific pre-approval by the Audit Committee.

All audit services, as well as the audit-related and non-audit services that are expected to exceed the amounts stated above, must be approved in advance of provision of the service by formal resolution of the Audit Committee. At the regularly scheduled Audit Committee meetings, the Committee reviews a report summarizing the services, including fees, provided by the Auditor.

(e)(2) Services approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X:

Audit-Related Fees, Tax Fees and All Other Fees:

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception under Rule 2-01 of Regulation S-X.

(f) According to the registrant’s principal accountant, for the fiscal year ended December 31, 2014, the percentage of hours spent on the audit of the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons who were not full-time, permanent employees of principal accountant was less than 50%.
