The Procter & Gamble Future Shares Plan On October 14, 1997, the Company's Board of Directors approved The Procter & Gamble Future Shares Plan pursuant to which options to purchase shares of the Company's common stock may be granted to employees worldwide.
The purpose of this plan is to advance the interests of the Company by giving substantially all employees a stake in the Company's future growth and success and to strengthen the alignment of interests between employees and the Company's shareholders through increased ownership of shares of the Company's stock.
The plan has not been submitted to shareholders for approval.
Subject to adjustment for changes in the Company's capitalization, the number of shares to be granted under the plan is not to exceed 17 million shares.
Under the plan's regulations, recipients are granted options to acquire 100 shares of the Company's common stock at an exercise price equal to the average price of the Company's common stock on the date of the grant.
These options vest five years after the date of grant and expire ten years following the date of grant.
If a recipient leaves the employ of the Company prior to the vesting date for a reason other than disability, retirement or special separation (as defined in the plan), then the award is forfeited.
At the time of the first grant following Board approval of the plan, each employee of the Company not eligible for an award under the 1992 Stock Plan was granted options for 100 shares.
From the date of this first grant through June 30, 2003, each new employee of the Company has also received options for 100 shares.
Following the grant of options on June 30, 2003, the Company suspended this part of the plan.
The plan terminated on October 13, 2007.
The Gillette Company 2004 Long-Term Incentive Plan Shareholders of The Gillette Company approved The Gillette Company 2004 Long-Term Incentive Plan on May 20, 2004, and the plan was assumed by the Company upon the merger between The Procter & Gamble Company and The Gillette Company.
All options became immediately vested and exercisable on October 1, 2005 as a result of the merger.
After the merger, all outstanding options became options to purchase shares of The Procter & Gamble Company subject to an exchange ratio of .975 shares of P&G stock per share of Gillette stock.
Only employees previously employed by The Gillette
The expected weighted-average life of securities available for sale was 3 years and 6 months at December 31, 2007, 3 years and 8 months at December 31, 2006, and 4 years and 1 month at December 31, 2005.
The following table presents unrealized loss and fair value of securities at December 31, 2007 and December 31, 2006 for which an other-than-temporary impairment has not been recognized.
These securities are segregated between investments that have been in a continuous unrealized loss position for less than twelve months and twelve months or more.
## Table 1 ##
We do not believe any individual unrealized loss as of December 31, 2007 represents an other-than-temporary impairment.
The $313 million unrealized losses reported for mortgage-backed securities relate primarily to securities issued by the Fannie Mae, the Federal Home Loan Mortgage Corporation and private issuers.
For those securities issued by private issuers, substantially all of the securities were rated “AAA” by at least two major ratings agencies.
The $16 million unrealized losses reported for commercial mortgagebacked securities relate primarily to fixed rate securities.
The $112 million unrealized losses associated with asset-backed securities relate primarily to securities collateralized by home equity, automobile and credit card loans.
The majority of the unrealized losses associated with both mortgage and assetbacked securities are attributable to widening market credit spreads, primarily affecting the mortgage-backed and assetbacked security sectors, and not from the deterioration of credit quality.
Of those securities in an unrealized loss position for 12 months or more as of December 31, 2007, 32 (19 mortgagebacked, 6 asset-backed, 5 commercial mortgage-backed, and 2 state and municipal) positions with fair value totaling $640 million had an unrealized loss of more than 5% when compared with their amortized cost.
The unrealized loss on these positions totaled $50 million and the unrealized loss amount on any individual position did not exceed $8 million.
The mortgage-backed securities are primarily collateralized mortgage obligations where amortized cost approximates the par value of the security.
These securities are all rated “AAA.
” The asset-backed securities include six positions with an aggregate unrealized loss of $10 million.
These securities are all rated “AAA” with the exception of one security with amortized cost of $4 million and an unrealized loss of $2 million that was rated below investment grade.
The aggregate unrealized loss on the commercial mortgage-backed and state and municipal securities positions was not significant.
## Table 2 ##
Commitments to extend credit represent arrangements to lend funds subject to specified contractual conditions.
At December 31, 2007, commercial commitments are reported net of $8.9 billion of participations, assignments and syndications, primarily to financial services companies.
The comparable amount at December 31, 2006 was $8.3 billion.
Commitments generally have fixed expiration dates, may require payment of a fee, and contain termination clauses in the event the customer’s credit quality deteriorates.
Based on our historical experience, most commitments expire unfunded, and therefore cash requirements are substantially less than the total commitment.
Consumer home equity lines of credit accounted for 80% of consumer unfunded credit commitments.
Unfunded credit commitments related to Market Street totaled $8.8 billion at December 31, 2007 and $5.6 billion at December 31, 2006 and are included in the preceding table primarily within the “Commercial” and “Consumer” categories.
Note 24 Commitments and Guarantees includes information regarding standby letters of credit and bankers’ acceptances.
At December 31, 2007, the largest industry concentration was for general medical and surgical hospitals, which accounted for approximately 5% of the total letters of credit and bankers’ acceptances.
At December 31, 2007, we pledged $1.6 billion of loans to the Federal Reserve Bank (“FRB”) and $33.5 billion of loans to the Federal Home Loan Bank (“FHLB”) as collateral for the contingent ability to borrow, if necessary.
Certain directors and executive officers of PNC and its subsidiaries, as well as certain affiliated companies of these directors and officers, were customers of and had loans with subsidiary banks in the ordinary course of business.
All such loans were on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other customers and did not involve more than a normal risk of collectibility or present other unfavorable features.
The aggregate principal amounts of these loans were $13 million at December 31, 2007 and $18 million at December 31, 2006.
During 2007, new loans of $48 million were funded and repayments totaled $53 million.
